Baomain PCB Power Relay JQC-3F (T73) 3VDC SPST 7A 240VAC 10A 125VAC/28VDC 5 Pins Pack of 10

The pin spacing on this doesn't fit the .01" spacing on prototype boards. Be prepared to drill. Other than that, it works great. I needed a 3 VDC coil and knew ahead of time about the spacing problem.

These are terrible relays. I bought two packs through the purchasing office at my university, and, so far, 8 out of 10 have failed. Either they failed right away, or they failed within a few minutes.They start spontaneously opening and closing their internal switch, and that renders them useless. The ones we got from another source are much better quality - out of 50 received, only one failed.I cannot recommend these for any purpose.
