A11CSP24VDC1.5R

Relay Automotive Overview

The A11CSP24VDC1.5R is a sealed automotive relay manufactured by CIT Relay and Switch, designed for high-current switching applications in vehicle electrical systems. It features a single pole double throw (SPDT) contact arrangement with one changeover set (Form C). The device operates on a 24VDC coil voltage and supports a maximum switching current of 30A. Constructed with PC pin termination, it utilizes through-hole mounting for secure PCB integration. The relay is rated for operation within a temperature range of -40°C to +85°C, ensuring reliability in harsh automotive environments. It complies with RoHS directives and carries cURus certification.

Relay Automotive Procurement Notes

Verify the specific ordering suffix matches the required contact arrangement and coil voltage. Confirm that the PC pin pitch aligns with the target PCB footprint. Ensure the sealed design meets the environmental protection requirements of the intended application. Cross-reference the cURus certification marks if regulatory compliance is mandatory for the final assembly.

Relay Automotive Selection Notes

Select this component when a 24VDC coil drive is available and a 30A SPDT switching capability is required. Consider the sealed housing for protection against moisture and contaminants typical in automotive under-hood or exterior locations. Evaluate the through-hole mounting constraints against available board space. Compare thermal performance within the specified -40°C to +85°C operating range against local ambient conditions.

Relay Automotive Part Context

This part belongs to the A1 Series from CIT Relay and Switch, which focuses on automotive and lamp accessory solutions. The series emphasizes compact form factors combined with high current ratings. The A11CSP24VDC1.5R specifically addresses the need for reliable switching in 24-volt vehicle architectures, offering a balance between physical size and electrical throughput for auxiliary loads.

Relay Automotive Replacement Considerations

Direct substitutes must match the 24VDC coil, 30A SPDT rating, and PC pin terminal style. Verify mechanical dimensions and sealing standards to ensure interchangeability without redesigning the PCB layout.
