Relay Automotive Procurement Notes

Verify the specific suffix 'R' indicates the inclusion of a built-in resistor or suppressor component as per manufacturer documentation. Confirm that the package type matches tray requirements if applicable. Ensure the coil voltage rating aligns strictly with 12VDC system designs. Cross-reference the contact material AgSnO2 for compatibility with intended load types. Validate RoHS compliance status against current regulatory standards before finalizing procurement orders.

Relay Automotive Selection Notes

Select this model when a sealed, high-current relay is required for 12VDC automotive applications. The 40A rating suits most standard vehicle loads. Consider the SPST-NO configuration for simple on/off control. The quick connect terminals facilitate rapid assembly. Verify thermal management needs given the operating range extends to 125°C. Ensure the physical dimensions fit the designated chassis or panel space constraints.

Relay Automotive Part Context

This component belongs to the CIT A2 series of automotive relays, characterized by robust switching capabilities and compact sizing. The A2M variant specifically denotes a medium-sized relay within the lineup, balancing performance and footprint. It is engineered for reliability in vibration-prone automotive settings. The series typically includes various coil voltages and contact arrangements to support diverse circuit requirements.

Relay Automotive Replacement Considerations

Direct substitutes may include other CIT A2 series models with identical pinouts and ratings, such as A2M1ASQ12VDC1.6 without the R suffix if the resistor is not critical. Verify mechanical dimensions and terminal spacing match exactly. Check if alternative manufacturers offer equivalent SPST-NO 40A 12VDC sealed relays with compatible mounting styles.
