A2F1CSP24VDC1.6

Relay Automotive Overview

The A2F1CSP24VDC1.6 is an automotive relay manufactured by CIT Relay and Switch, designed for high-current switching applications. It features a coil voltage of 24 VDC with a maximum rating of 31.2 VDC and consumes 1.6 watts of power. The contact configuration is SPDT (1 Form C), supporting a maximum switching current of 40A at 14VDC and a maximum switching voltage of 75VDC. With a contact resistance of less than 30 milliohms and AgSnO2 contact material, it offers large switching capacity up to 40A in a compact form factor.

Relay Automotive Feature Summary

• Large switching capacity up to 40A
• Small size and light weight design
• PCB pin and quick connect mounting available

Relay Automotive Applications

• Automotive electrical systems
• Lamp accessories control
• High-current circuit switching

Relay Automotive Procurement Notes

Verify the specific datasheet version against the manufacturer's official documentation to confirm exact mechanical dimensions and thermal characteristics. Ensure that the 24VDC coil voltage aligns with the target system's power supply capabilities. Confirm that the SPDT contact arrangement meets the required circuit logic. Check RoHS compliance status if environmental regulations apply to the end product assembly process.

Relay Automotive Selection Notes

Select this component when a robust SPDT relay capable of handling 40A loads is required within automotive or industrial environments. The 24VDC coil specification suits standard heavy-duty vehicle electrical architectures. Consider the physical mounting options, including PCB pins and quick connects, to match the assembly constraints. Verify that the 75VDC maximum switching voltage is sufficient for the intended load protection requirements.

Relay Automotive Part Context

This model belongs to the CIT A2 series of automotive relays, characterized by high current ratings and compact packaging. The series is certified under QS-9000 and ISO-9002 standards, indicating adherence to strict manufacturing quality controls. The A2F1CSP24VDC1.6 variant specifically integrates a 24VDC coil with SPDT contacts, distinguishing it from other variants with different coil voltages or contact configurations.

Relay Automotive Replacement Considerations

Direct substitutes include models with identical 24VDC coil ratings and SPDT contact arrangements, such as the A2H1CSP24VDC1.6. Verify mechanical footprint compatibility before substitution. Ensure that any alternative part maintains the 40A switching capacity and 75VDC voltage rating to prevent circuit failure.
