Greetings, everyone -

I've seen searching Mouser all afternoon trying to identify a footprint equivalent for an existing relay (specifically, subminiature, for the SY-12-K.) The contacts for this particular relay can only carry 1A, and I need something that is of the same form factor that can carry 2.5A that is also 12V. This is my own circuit, it can handle the additional current (1A was fine in the 90s, but 2.5A is needed nowadays for what I'm controlling), and I'd rather not make a bunch of PC boards and retrofit field solutions if I can simply just solder a new relay in place across several field deployments.

I have the datasheet, and have been clicking and refining my searches for about the past two hours, trying to find something with the same pin configuration, motherboard footprint, etc., with no avail.

So, I figured I'd come here in desperation after all this searching (including past threads in here) with two educated questions:

1) Is there a standard set of form factors for relays? If so, what is it, and what is this relay considered? I can't find anything in search other than very general information.

2) If there isn't an "official" standard, is there a better way to find what I'm looking for other than randomly refining searches and trying to find something on Mouser? It's not easy to search by dimension.

Thank you all!
