1、Parts Lookup and ordering guide This material is intended for use by anyone who comes in contact with ONKYO electronic parts. Service parts order, parts administration, warranty administration, inventory control, data base development, and technical departments may use this information for all appro

2、priate purpose. RadioFans.CN 收音机爱 好者资料库 ONKYO PARTS LOOKUP and TERMINOLOGY The beginning of service manual often will indicate which part number within the list to pick when ever a replacement part order is needed. This is specially important whenever ordering PCBs and power supply components and Tu

Page 1 Example: RadioFans.CN 收音机爱 好者资料库 ONKYO PARTS LOOKUP and TERMINOLOGY Onkyo uses few method to present part numbers of a verity components used in its production. Please use these as a guide line to help you look up parts and or identify parts quickly. 3. M

4、echanical parts are of those which help mount, hold, fasten and cover the above parts listed in boxes 1 and 2 and give the product a given operational, structural and cosmetics look. Example: 15, 13, 5, 16 etc . 2. Fuses, Transformers, Lead Connectors, Jacks, Tape, Insulators, and Large semiconducto

5、rs may be given location ID within mechanical layout section. If you do not find these components within the schematic location, they may be found here. Example: F933, F911, Q624, Q526, E811, P101, E801 T901 etc. 1. PCBs locations and part numbers are often times found along side structural hardware

6、 components referred to as Exploded View of Mechanical. They may be labeled as U# while other structural assembly components may be given a numbers only. Example: U18, U9, U2, U1, etc. TX-DS575X Page 2 RadioFans.CN 收音机爱 好者资料库 ONKYO PARTS LOOKUP and TERMINOLOGY Mechanical parts list for items shown o

7、n page 1 may be found listed here. As you notice some semi conductors are also listed here which are often associated to being output transistors and ICs, Rectifier Bridge Diodes, Regulators, and fuses.

8、. Notice T902 how it is drawn. It indicates a transformer. Wherever you see this type of drawing, it may be a transformer but with different applications. This shape indicates that this is an AC plug. A four diode configuration such as this is considered bridge configuration. In this case four same

9、type diodes are being used having different location. If this was a single package it would have one location since the part is only one. A component of this layout with arrow pointing outward is considered NPN transistor. If the Arrow is pointing inward, it is a PNP. These symbols are indicators of

10、 critical part. Must replace parts with original parts only. Fuse symbol Relay symbol AC outlet symbol Ceramic Capacitor symbol Electrolytic Capacitor symbol Resistor symbol for all types. Resistor symbol with critical component marking next. ONKYO PARTS LOOKUP and TERMINOLOGY Here we see component

11、listed with an OR statement attached to the description of the parts. We refer to these parts as complementary Pairs as indicated by the colored lines only. The parts can be substituted but must maintain the complementary of the substituted part. Example-1: If Q6053 originally was found to be 2SC520

12、0-O with its complementary of Q6063, 2SA1943-O the sub to be matched with will be 2SC5200-R and 2SA1943-R. Example-2: For the above scenario another sub will be MN150S-Y with its complimentary pair MP150S-Y NPN Transistors PNP Transistors Majority of the times, parts list looks like this. All these

13、parts are considered interchangeable for these given application. * Please note the suffix for each transistor description. The suffix color code always must match the suffix on the pair.

14、transistor manufacturers use a unique but simple method to keep order to the device naming order. Most transistor start with: 2SA# = 2= Means it is bipolar device, S= means Silicon, A= means it is PNP High frequency device. 2SB# = 2= Means it is bipolar device, S= means Silicon, A= means it is PNP L

15、ow frequency device. 2SC# = 2= Means it is bipolar device, S= means Silicon, A= means it is NPN High frequency device. 2SD# = 2= Means it is bipolar device, S= means Silicon, A= means it is NPN Low frequency device. DTA# = D= means it is digital, T= means Transistor, A= means it is a PNP low frequen

16、cy device. DTC# = D= means it is digital, T= means Transistor, C= Means it is a NPN high frequency device. Not all transistors have matched pairs: If they did, the match pairs are found within their perspective operating frequency group. For a transistors labeled 2SA its matched pair can only be fou

17、nd within the transistor group of 2SC. For a transistors labeled 2SB its matched pair can only be found within the transistor group of 2SD. When forming a matched pair, one MUST maintain the group order. Example of a critical application: 2SC5200-O NPN Transistor has a matched pair (complementary) o

18、f 2SA1943-O. The sub for 2SC5200-O Transistor may be 2SC5200-R which has a pair (complimentary) 2SA1943-R. The Pair 2SA1943-R can not be paired with 2SC5200-O in a proper service environment as it will jeopardize the specific performance of the item. Assuming one is forced to substitute 2SC5200-O wi

19、th 2SC5200-R, it would mean also replacing its matched pair (complementary) from 2SA1943-O to 2SA1943-R as well.

20、le Match Pair. Not acceptable substitute Not acceptable substitute Suffix to a device is to show its differing specification form same classification and ID part. ONKYO PARTS LOOKUP and TERMINOLOGY Even though both are PNP, the two belong to two different classification. Subbing B to A or A to B is

21、not recommended without all the engineering facts addressed. Both may be NPN but belong to different classification . Sub between C and D is not often recommend ed. Not acceptable substitute Page 7 If one of the Pair parts must be substituted, one also must replace the Pair following the given guide

22、line. The Sub for A may be found in A, for B in B, for C in C and for D in D unless specifically recommended by ONKYO. See page 5 The pair for A is C and the pair for B is D. true only if the Suffixes of the transistors are the same. Two are considered only when the pairs suffixes correspond. A comp

23、onent having a Suffix (O) is only a match to a pair having same suffix (O). (See pages 5, 6, and 8). If two components are made to operate as matched pairs such as in power amplifier drivers and output stages, consider maintaining the safety and integrity rules as provided. It is also important to k

24、now some of these devises may be applied in critical safety noted circuitry such as switching power supply and regulators. Therefore, one must do all that is possible to keep the part replacement order as indicated in the manual. Should you find a part is not in a stock or back ordered, please make

25、the appropriate parts lookup to obtain a substitute but matched pair. ONKYO PARTS LOOKUP and TERMINOLOGY Important Note: Page 8 ONKYO PARTS LOOKUP and TERMINOLOGY 2SC# - O 2SA# - O 2SC# - R Correct Match pair Not acceptable match pair Not acceptable Match Pair. 2SC# - 8F 2SA# - 8F 2SC# - 7G Correct

The pair for A is C and the pair for B is D. If two components are made to operate as matched pairs such as in power ampli

Page 11 ONKYO PARTS LOOKUP

32、 and TERMINOLOGY ZOOM ONKYO PARTS LOOKUP and TERMINOLOGY Most Onkyos PCB parts have PCB ID which can be seen printed on the PCB towards a corner edge. These IDs are NOT part numbers, rather a Production Descriptive Name ID. The PCB below is a TX-DS989DSP (digital) Signal Processor) assembly. The PCB

33、 ID on this PCB is seen top left (See zoomed image). NCDG-6830 is a descriptive ID prior to PCB being populated with components. Service manual refers to these as NADG-6830 indicating it is a populated PCB. The number below it 25136830B is not a part number. Its Suffix at the end of the digits indic

34、ates production series. Second character in NADG-6830 (NCDG-6830) indicates it is a populated PCB. The last character in 25136830B indicates revision made or production series. In this case this PCB is a second revision or production series. The suffix is significant ID at times referenced when ever service bulletin is being introduced. Example: A bulletin may say a given modification may apply to A and B PCB production but not later versions such as C,D,E or F. Page 12
