| J1 connector (Plus analog board) | |
| Posted by: tanaquil on 2018-08-20 18:59:57 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? | |

| Posted by: Crutch on 2019-01-19 16:43:03 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? | |
| Posted by: LaPorta on 2019-01-19 17:14:03 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. | |
| Posted by: chu-oh on 2019-01-19 20:42:50 I wonder if you could dremel/cut the shielding off a male molex connector and use that?  | |
| Posted by: superjer2000 on 2019-01-19 20:47:02 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. | |
| Posted by: tanaquil on 2019-02-27 08:02:22 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! | |
| Posted by: Jinnai on 2019-02-27 14:19:45 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. | |
| Posted by: Johnnya101 on 2019-02-27 14:23:07 Do you just need the plastic part itself? Could always design and 3d print some. | |
| Posted by: pbertolo on 2019-08-20 12:56:08 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. | |
