AZ989-1C-12DSE

Relay Automotive Overview

The AZ989-1C-12DSE is a sub-micro automotive relay manufactured by American Zettler. It features a single-pole double-throw (SPDT) contact configuration with one Form C switch. The coil operates at 12 VDC with a resistance of 180 Ohms and draws approximately 66.7 mA. The contacts are rated for 25 A at up to 32 VDC or 14 VAC, supporting resistive loads. Designed for through-hole PCB mounting, the unit measures 14.3 x 7.5 x 13.8 mm. It complies with UL standards and includes epoxy sealing for environmental protection.

Relay Automotive Procurement Notes

Verify that the specific suffix 'DSE' matches the required packaging or tape-and-reel specifications if applicable, as standard variants may differ. Confirm that the 12 VDC coil voltage aligns with the target system's supply rails. Ensure the PCB footprint accommodates the 14.3 x 7.5 mm dimensions and six-pin through-hole layout. Check for any specific UL certification requirements relevant to the end-use application before finalizing component selection.

Relay Automotive Selection Notes

Select this component when a compact SPDT relay is required for 12 VDC automotive environments. The 25 A rating suits moderate current loads such as motors and solenoids. Consider the physical dimensions against available board space. Verify that the operating temperature range meets environmental conditions. Ensure the coil drive circuit can supply the necessary current without exceeding voltage limits.

Relay Automotive Part Context

This part belongs to the AZ989 series of sub-micro automotive relays from American Zettler. The series is characterized by high current density in small packages. Variants within the series differ by contact configuration (Form A, B, or C) and coil voltage. The AZ989-1C-12DSE specifically denotes the 12 VDC coil version with SPDT contacts and epoxy sealing.

Relay Automotive Replacement Considerations

Direct substitutes include other 12 VDC SPDT automotive relays with similar current ratings and pinout configurations. Verify mechanical compatibility and electrical parameters before swapping. Generic replacements must match the 25 A contact rating and 12 VDC coil specification.
