Power Relays, Over 2 Amps Procurement Notes

Verify that the specific part number matches the required coil voltage and contact configuration. Confirm that the supplier provides original manufacturer documentation. Ensure the product complies with RoHS directives if applicable to your region. Check for any specific handling instructions regarding moisture sensitivity during storage and assembly processes.

Power Relays, Over 2 Amps Selection Notes

Select this component when space constraints require a miniature relay with a 3.5 mm pin pitch. It is appropriate for applications needing a single changeover contact rated at 10A. Consider the 120VAC coil requirement against available control voltages. Evaluate the need for socketability versus direct PCB mounting based on maintenance requirements.

Power Relays, Over 2 Amps Part Context

This relay belongs to Finder's 40 Series, a line of miniature PCB relays known for their compact size and high switching capacity. The series includes variants with different pin pitches and pole configurations. The 40.31 variant specifically offers a 3.5 mm pitch, distinguishing it from the wider 5 mm pitch models in the same family.

Power Relays, Over 2 Amps Replacement Considerations

Direct substitutes may include other 40 Series models with identical coil voltage and contact ratings but different pin pitches. Verify compatibility with existing PCB footprints or sockets before replacing. Cross-reference with other manufacturers' miniature relays ensuring matching electrical ratings and physical dimensions.
