J1 connector (Plus analog board)

[tanaquil]

Does anyone know where I can buy a replacement J1 connector (one of the white plug in connectors, with four pins)? Mine has the classic burned out pin 4 that Larry Pina describes as the result of a C1 failure. He says it has to be replaced once burned,  but I haven’t seen one in anyone’s DigiKey or similar parts list. Is robbing a donor board the only option? Or can it be replaced with something common like a molex connector?

The J1 connector is the one right next to the "missing" HOT in this picture. I think it is the yoke connector that plugs into it.

Bump. Same problem. I have a fried J1 connector. Anyone know if it’s possible to source one anywhere? @tanaquil did you ever find one?

I'm pretty sure you can work anything that has equal male and female ends to replace it. Just depends if you care about originality.

I wonder if you could dremel/cut the shielding off a male molex connector and use that?

Is there not a part number somewhere on the connector (either end)?  I found the molex part number for the analog to logic board connector by reading the ultra tiny type on that molex connector.

Sorry been away from the forums - no, the only solution I ever found was to cannibalize another board. I'll have to try looking at the connectors under a magnifying glass to see if I can find a part number. If anyone ever finds a solution that works for them, please post it here!

Well, I know a guy with a custom cable manufacturing company, he specializes in making these kinds of connectors, but developing a die might be expensive - the last quote I got from him was $700. So there'd have to be enough demand, but the result would likely be both the molded connectors and pins if needed.

Do you just need the plastic part itself? Could always design and 3d print some.

Hi Guys,

same problem on (most of) my classic Macs.

After some search, 1:1 replacements exist and are available.

Molex > PART NUMBER:19091049 

Digi-Key Part Nr WM1606-ND

Molex > PART NUMBER:15311046

Digi-Key Part Nr WM1042-ND

Both parts seem to be active and available.
