AZ9871-1A-12DET

Relay Automotive Overview

The AZ9871-1A-12DET is a micro automotive relay manufactured by American Zettler, designed for through-hole mounting with PC pin termination. It features a single-pole single-throw normally open (SPST-NO) contact configuration rated for 30 A at a maximum switching voltage of 24 VDC. The coil operates on 12 VDC with a current draw of 47.2 mA and resistance of 254 Ohms. Key electrical parameters include an operate time of 3 ms and a release time of 1.5 ms. The unit utilizes silver tin oxide contact material and offers epoxy sealing for environmental protection, functioning within a temperature range of -40°C to 105°C.

Relay Automotive Feature Summary

• Epoxy sealed construction provides environmental protection against moisture and contaminants
• Silver tin oxide contact material ensures reliable switching performance under load
• Through-hole PC pin termination facilitates direct printed circuit board integration

Relay Automotive Applications

• Automotive electrical systems
• Vehicle lighting circuits
• General purpose switching applications requiring high current capacity

Relay Automotive Procurement Notes

Verify the specific part number suffix to confirm the sealed variant designation. Ensure compatibility with the target PCB footprint for PC pin termination. Confirm that the 12VDC coil voltage aligns with the system power supply requirements. Check RoHS compliance status if restricted substances are mandated by the end product specifications.

Relay Automotive Selection Notes

Select this component when a robust SPST-NO relay is required for automotive or industrial environments. The 30A rating supports high-current loads such as lamps or motors. Consider the 12VDC coil requirement and the operating temperature range up to 105°C for thermal management. Verify that the through-hole mounting style fits the mechanical constraints of the assembly.

Relay Automotive Part Context

This device belongs to the AZ9871 series of micro automotive relays from American Zettler. The series includes variants with different contact forms and coil voltages, such as the AZ9871-1C-12DET which offers a changeover contact configuration. The AZ9871-1A-12DET specifically denotes the single-pole single-throw normally open version with a 12VDC coil.

Relay Automotive Replacement Considerations

Direct substitutes within the same family include AZ9871-1A-24DET for 24VDC coil operation. For changeover functionality, consider AZ9871-1C-12DET. Cross-manufacturer replacements require matching SPST-NO form, 30A current rating, 12VDC coil, and PC pin termination.
