Frequently Asked Questions

Q: Are these SIP-1A05 reed relays compatible with PAN CHANG relay sockets?

A: Yes. The SIP-1A05 is designed as a direct replacement for PAN CHANG relay applications. The 4-pin SIP footprint matches standard PAN CHANG-compatible PCB sockets, making swapping or repairing boards straightforward.

Q: What does "disassembled part" mean for these relays?

A: These reed relays have been removed from previously assembled boards or equipment — they are pulled/salvaged components rather than factory-sealed new stock. They are tested-functional but may show minor cosmetic marks. Please confirm this is acceptable for your project before ordering.

Q: Can I use these relays with a 5V microcontroller such as an Arduino?

A: Absolutely. With a 5V DC operating coil and a normally open contact rated at 1A, these relays are well-suited for direct interfacing with 5V microcontroller platforms like Arduino when used with an appropriate transistor driver or relay module.
