Once more Sansui transistor substitutions

Sansui transistor substitution collection

Hi, I've been busy figuring out transistor substitutions for my AU20K. While at it I also went through BA-2000 and AU-717 service manuals to find other transistors used originally in these things and searched the forum. The info is scattered in many many threads, maybe there already is a collection of these somewhere but I didn't find it. Meanwhile I have found many more references for other Sansui model's transistors and suitable substitutions in the forum. They are also listed below. If there was any doubt in the discussion about suitability I didn't add them to the list.

Here is the list I gathered from AK Exclusively Sansui -section. So, its not an AU20K list but rather a general Sansui list. If you spot an error please point it out, I'll update the list. Also if you know better or more suitable substitutions or transistors which are missing from this list please let us know. All additional info like if the pin order differs from original, case type, ideal usage etc. is welcome.

If there is more than one Substitution it means there is more than one option. Ie. somebody on this forum has suggested or even used these types.

Note: the suffixes might be suspect on some of these so double check from the specsheet what they mean. These transistors are all something that has been suggested by reputable forum users but frankly I don't know what most of the suffixes mean or if they are the optimal for the use. Please recheck before using and use at your own risk.

Note 2: complementary pairs have not been marked. If you need them in pairs google for the datasheet or search Mouser etc. vendor sites for the the substitute and you will find the datasheet. It usually says what the correct complementary pair is.

------------------------

Here is some diode and zener subs I've seen mentioned while collecting transistors:

Diodes/rectifiers:
10D1 --- 1N5392, 1N5393
10D2 --- 1N5392, 1N5393
30D2 --- 1N5402G
1S1588 --- 1S2473, 1N4148
1S2473 ---- 1N4148, 1N4149
VD1212 --- 2pcs of 1N4148 connected in series
1S1850 --- MUR1620CTG (TO220) - or use 1N5393G (200V 1.5A) or 2A03 (200V/2A) to make your own Common Cathode -diode pack
1S1850R --- MUR1620CTRG (TO220) - or use 1N5393G (200V 1.5A) or 2A03 (200V/2A) to make your own Common Anode -diode pack

Zeners
EQB01-22 --- BZV85-C22 or 1N4748A
RD-13A --- TZX13A-TR
RD-15E --- ??? Maybe 1N5245BTR, comments?
RD-22E --- ??? Maybe 1N5251BTR, Comments?


I've noticed I myself have difficulty sometimes finding this thread so here are some search terms: substitution, substitutions, subs, substitute.

 

Nice idea - well done Toni.

2SA818 --- KSA1381,
2SC1628 --- KSC3503,

They should both be noted as "pin order"

 

really nice to bring that info together!!!!
Thanks I appreciate it
from john rather recently regarding an au666

2sc871 --- 2sc2240, KSC1845, or even BC549C or BC550C (pin out differences!)

 

I'm surely impressed....you have probably minimized many future posts about Sansui replacements by tying all together in one thread....thanks again

 

Hope it helps.

Post #1 updated with more transistors + some diodes and zeners.

Keep the additions, corrections and extra info coming! :thmbsp:

 

+1 on finding a replacement for RD-15E zener diode

 

Sansui transistors sub

Hello ToniCH

You said :

2SA958 --- 2SC2168

I think that if you replace a 2SA958 by 2SC2168 you will get some problem !

I did not control all your list but these ref attract my eyes !

:thmbsp:

 

Nice !!!!

 

2SA899 --- KSA1142, KSA1220AYS
Also KSA1381

 

Good work Toni!

Here are some substitutions I used on my G-6700 and G-4700:

2SA939 - KSA1381
2SA968 - MJE15033

2SB527 - KSA1220

2SC2071 - KSC3503
2SC2238 - MJE15032

2SD357 - KSC2073
.

Updates: (12/28/14)

2SB507(E,F) - KSA1010Y

2SC1983 - TIP112F or KSD1273Q

2SD313(E,F) - KSC2334Y

 

just looking for substitution for my G-4700 transistors.
great post and thanks a lot.

 

Toni this is from AUD-101 ( condense as needed ) The MUR's work great!
Hey Mike,
Mouser has TO220 types that maybe could be used as replacements(?) - will need to check pin spacing etc ---> MUR1620CT & MUR1620CTR - (Yes these are bit over-kill on the spec's!)...or you could fudge together two single diodes to form either a common cathode and common anode rectifier - Some online spec/datasheets either list the 1S1850 / 1S1850R as 200V/1.5A or 2A - Therefore these are possible candidates ---> 1N5393G (200V 1.5A) or 2A03 (200V/2A)

Tommy without you saying what devices are in your unit... kinda hard to sub...

 

Thx for the list.

 

This is awesome!! Thanks

 

These should considered a sticky for transistors:yes:

Salute for your effort:thmbsp:

 

Fantastic list

Great work. This should be a sticky. Saves a load of searching.

 

Having taken on an attempt to do this kind of thing for the SX-1250 I know how much work it can become. The biggest problem I ran into was the fluidity of any list, due to discontinued items and items that were out of stock and out of stock for long periods of time. Your work is appreciated by me and many others. I do know just how hard this is.

 

Good post

Many thanks!

 

Thanks again this should be a STICKY... Saved me a TON of time on hunting replacements for my BA-2000 resto.

 

KSC1845EBU = Obsolete

Superceded by = KSC1845FTA (PIN ORDER!!)
Must install them backwards of original 2SC1313 which is BCE the KSC1845FTA is ECB.

Thanks again this list is AWESOME!
