GK-3 Internal 8-Pin header connector sources
« on: July 29, 2013, 09:02:17 AM »
Does anyone know of a source for the white plastic 8-Pin header connectors used by Roland, Fishman, etc. to connect the divided pickup cable to the preamp boards?  I need a few of them, so used/broken GK's is not a good option.  Thanks for any help.

Review the Parts List, where all part numbers are listed.

For example here is the GK-3 Internal Pickup 8 pin connector for the internal GK-3 Preamp PC board.

You will locate :
"F3417191  B8B-ZR JST  P=1.5 8P CONNECTOR CN2 on Main Board"

this breaks down to

"F3417191"  =  Roland Part Number F3417191

"B8B-ZR JST" = J.S.T. Part Number "B8B-ZR"(LF)(SN)

"P=1.5 8P CONNECTOR CN2 on Main Board" = Description of part type and where used. This is a 8 pin White connector with 1.5mm pitch single Inline Connector sourced from J.S.T.

Google Search on "B8B-ZR JST"

Gets you to  Digikey:

Digikey Part Number # 455-1663-ND
J.S.T. # B8B-ZR"(LF)(SN)


The ONLY connector on GK-KIT-GT-3 Internal preamp board with a 1.5mm pitch is the HEX PUP connector ...All others are 2mm


Here are all the connector Part numbers from DigiKey (thanks to member "oscope")

The price varies
http://www.amazon.com/Engineer-PA-09-Micro-Connector-Crimpers/dp/B002AVVO7K

I bought mine here 3 years ago  - $59

The price might seem high, but remember the "official" crimping tool for these connectors typically runs several hundred dollars.

Another option is locate a local advanced Radio Control Car/Truck/Plane Club or Robotic Control Hobbyist, as many of those guys seem to own a pair of Engineer PA-09 Crimpers in their tool crib, because all the servo motors use these same type connectors.

Also - Many third party Molex,TTI,Amp,Hirose,JST,JAL, Oupiin, etc, "2mm pitch single row connectors" are all cross compatible

Elantric, thank you so very much!  That is exactly what I was looking for.  I have lots of the 2mm parts on various scrap boards, I just figured this high density connector was some specialty item.  Glad to see Digikey has them.  It's funny, I'd already found & been through the threads w/ the schematics, since I'd needed that info as well, but I missed the parts list somehow... duh

If you do the math - its often cheaper to buy 8 pin 1.5mm JST connectors from an Asian vendor on Ebay


Micro JST 1.5 ZH 8-Pin Connector Plug w/.Wire x 10 sets $7.29 - free shipping - should arrive in 10 days to USA.
