Relay Automotive Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure compatibility with required coil voltage and contact configuration. Confirm RoHS compliance status and manufacturing certifications such as QS-9000 or ISO-9002 if required for your supply chain standards. Cross-reference the part number with the latest datasheet to confirm availability and any potential updates to specifications or lead times before finalizing procurement orders.

Relay Automotive Selection Notes

Select this component when a Mini ISO form factor is required for automotive or industrial applications needing 40A switching capacity. Ensure the system operates within the 75VDC maximum switching voltage limit. Verify that the 24VDC coil voltage matches the control circuitry and that the 1.9W power consumption is acceptable for the driving source. Confirm that the SPDT contact arrangement meets the logical requirements of the controlled load compared to alternative SPST configurations.

Relay Automotive Part Context

This model belongs to the CIT Mini ISO relay series, characterized by its standardized footprint and robust construction. It is engineered for durability in harsh environments, adhering to automotive industry standards. The series offers various coil voltages and contact arrangements to accommodate diverse switching needs while maintaining a consistent physical profile for easy integration into existing harnesses and sockets.

Relay Automotive Replacement Considerations

Direct substitutes may include other Mini ISO relays with identical 24VDC coil ratings and 40A SPDT contact configurations. Verify mechanical dimensions and terminal alignment to ensure fitment in existing sockets. Check that replacement units meet the same electrical ratings for voltage, current, and power dissipation to maintain system reliability.
