    I am trying to swap a relay but I can't seem to match the pinout. Both relays have 6 pins but they are not aligned the same way. I am not even sure if I can swap one with the other. I am trying to boost the amp that is why I am swapping them.

    Initial relay is: sla-12vdc-sl-c
    New relay is: 507h-1ah-f-s

    The initial relay has CHANGE-OVER contacts but the new one has only NORMALLY-OPEN contacts.

    If you need a change-over function then the new relay won't work.

    It was on a LINEAR LINFS20Z1, Z-Wave 20-Ampere.

    Not sure if that feature was needed. Guess I need to find something that matches the original...

    Digi-Key has part PB115-ND , however it is only rated at 20 Amps and I believe your original part is 30A.

    Might be worth a look though,

    I made a mistake, the original is 20a and new is 30a I believe.

    New relay is: sla-12vdc-sl-c
    Initial relay is: 507h-1ah-f-s

    But the original relay is only 17a so I was looking for something higher since I'm using this with a garburator which seemed to have killed the relay...

    Maybe you could use something like PB1323-ND and just wire it in to the circuit.

    with the schematic give you have 2 pins connected. Without having something to drop into the board this maybe an option.
