A171AS24VDC.96

Relay Automotive Overview

The A171AS24VDC.96 is an automotive relay from the CIT Relay and Switch A17 series, designed for through-hole mounting on printed circuit boards. It features a non-latching coil type with a 24 VDC coil voltage and 40 mA coil current. The contact configuration is SPST-NO (1 Form A), rated for 30 A switching current and up to 75 VDC switching voltage. Key electrical parameters include a 600 Ohm coil resistance, 960 mW coil power, 10 ms operate time, and 5 ms release time. It operates within a temperature range of -40°C to 85°C.

Relay Automotive Feature Summary

• SPST-NO contact configuration for single-pole single-throw normally open switching applications
• Non-latching coil design providing single-side stable operation without mechanical retention
• Sealed construction ensuring protection against environmental factors in automotive environments
• PC pin terminal style facilitating direct through-hole integration onto circuit boards

Relay Automotive Applications

• Lawn care and maintenance equipment control circuits
• Marine application electrical systems
• Agriculture machinery component actuation

Relay Automotive Procurement Notes

Verify the specific suffix designation when ordering, as variations such as .96R may indicate reel packaging or minor manufacturing updates that do not alter functional specifications. Confirm RoHS compliance status and MSL level requirements for your assembly process. Ensure the 24 VDC coil voltage matches your control circuit capabilities before procurement to prevent operational failure.

Relay Automotive Selection Notes

Select this component when a 24 VDC control signal is available and a single normally open contact path is required. The 30 A rating supports high-current loads, while the sealed design suits harsh environments. Consider the 600 Ohm coil resistance for driver current calculations. Verify that the through-hole footprint matches your PCB layout constraints and that the operating temperature range covers your application's extremes.

Relay Automotive Part Context

This part belongs to the CIT Relay and Switch A17 series, which includes various coil voltages and contact configurations. The A171AHS variant shares similar physical characteristics but may differ in specific electrical ratings or packaging options. The series is standardized for automotive and industrial use, offering consistent performance across different voltage and form factor combinations within the same product line.

Relay Automotive Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the SPST-NO form, 24 VDC coil, 30 A contact rating, and through-hole package dimensions. Verify compatibility with existing PCB footprints and thermal management requirements before substituting.
