AZ977-1C-24DE

Relay Automotive Overview

The AZ977-1C-24DE is a miniature power relay from the American Zettler AZ977 series, designed for automotive applications. It features a single pole double throw (SPDT) contact arrangement, designated as 1 Form C. The coil operates at a nominal voltage of 24 VDC. The relay supports a maximum switched current of 20 A and a maximum switched voltage of 150 VDC. It offers a mechanical life expectancy of 1 x 10^6 operations and an electrical life of 1 x 10^5 operations at 20 A. Key timing parameters include a maximum operate time of 10 ms and a release time of 7 ms at nominal coil voltage. The unit provides dielectric strength of 1000 VDC between coil and contacts.

Relay Automotive Feature Summary

• Compact footprint with up to 20 Amp switching capability suitable for space-constrained designs
• Vibration and shock resistant construction engineered for high in-rush applications
• Socketable design facilitating easy installation and replacement in automotive systems

Relay Automotive Applications

• Automotive power distribution circuits
• High in-rush load switching applications
• General purpose automotive control modules

Relay Automotive Procurement Notes

Verify that the specific suffix DE corresponds to the required lead-free and RoHS compliance status as documented by the manufacturer. Confirm socket compatibility and pinout alignment with the target PCB or harness design. Ensure the 24 VDC coil voltage matches the system supply to prevent improper actuation. Cross-reference the SPDT configuration against circuit requirements to avoid functional mismatches during integration.

Relay Automotive Selection Notes

Select this component when a compact relay with 20 A capacity is required for automotive environments. The 24 VDC coil rating must align with vehicle electrical systems. Consider the 1 Form C contact arrangement for switching loads requiring common terminal isolation. Evaluate thermal management needs given the resistive load ratings. Verify insulation resistance and dielectric strength requirements against safety standards applicable to the final assembly environment.

Relay Automotive Part Context

This part belongs to the AZ977 series of miniature power relays manufactured by American Zettler. The series includes variants with different coil voltages and contact arrangements, such as Form A configurations. The AZ977 line is characterized by low cost and robust performance in automotive sectors. Other models in the family share similar physical dimensions and switching capabilities but differ in electrical specifications.

Relay Automotive Replacement Considerations

Direct substitutes within the same series include AZ977-1C-12D for 12 VDC coil applications. Variants like AZ977-1C-24D may serve as alternatives if suffix differences do not impact compliance or packaging requirements. Ensure any replacement maintains the SPDT contact form and 20 A current rating.
