SSR Replacement Options

Thought for 2 mins 37 sec

You're right. The part G3MB-202P-DC12 is flagged obsolete in distributor data, and it isn’t actually placed in your BOM (it’s only referenced in project properties).

Next step is to pick a drop-in or near-drop-in SSR replacement:

Prefer same footprint and pinout if possible.
Match control input voltage, AC load voltage/current, and switching type (zero-cross vs random).
If a true drop-in isn’t available, choose a close spec and adjust footprints.

Initial candidates in the Flux library to evaluate (we’ll verify specs via datasheets once you confirm constraints):

G3MB-202P (family entry; potential drop-in depending on sub-variant)
G3MC-201P-VD-1 DC12 (Omron SSR, similar SIP-4 form factor)
G3MB-202P-DC5V (if 5 V control input is acceptable)

Quick questions so I can lock in the best replacement:

What control voltage/current do you have available for the SSR input (is it 12 V as implied, or something else)?
What AC load voltage/current and load type (resistive vs inductive)?
Do you require zero-cross switching and do you need the exact G3MB footprint, or is a different SIP-4 footprint acceptable?

Once you confirm these, I’ll shortlist active, in-stock parts and validate them against their datasheets. I can then swap the part in your project and add a vetted second-source option as well.
