AZ9731T5-1C-12DC2ED2

Relay Automotive Overview

The AZ9731T5-1C-12DC2ED2 is a Mini-ISO automotive relay manufactured by American Zettler. It features a Single Pole Double Throw (SPDT) contact configuration with a 50 Amp continuous current rating. The unit operates on a 12V DC coil voltage and utilizes chassis mounting for installation. This component is designed to handle high momentary carry currents, ensuring reliable performance in demanding automotive electrical systems.

Relay Automotive Feature Summary

• SPDT contact configuration for versatile switching applications
• High 50 Amp contact rating for heavy load management
• Mini-ISO form factor compatible with standard automotive fuse boxes
• Chassis mount design for secure physical installation

Relay Automotive Applications

• Automotive lighting circuits
• Heater and blower motor control
• Fuel pump power distribution
• General automotive accessory switching

Relay Automotive Procurement Notes

Verify the specific suffix ED2 against official American Zettler documentation to confirm terminal configuration and pinout compatibility. Ensure the 12V DC coil voltage matches the vehicle's electrical system requirements. Cross-reference the SPDT contact arrangement with circuit diagrams to validate functional suitability before procurement.

Relay Automotive Selection Notes

Select this model when a 50 Amp capacity is required within a Mini-ISO footprint. Confirm that the 12V DC coil specification aligns with available control signals. Evaluate the SPDT configuration against simpler SPST alternatives if only single-pole switching is necessary. Verify thermal ratings for high-temperature environments typical under-hood installations.

Relay Automotive Part Context

This relay belongs to the AZ9731T5 series of Mini-ISO automotive relays from American Zettler. The series provides robust switching solutions for modern vehicles. The T5 designation indicates specific terminal and housing characteristics distinct from other AZ9731 variants. It serves as a critical interface between low-power control signals and high-current loads.

Relay Automotive Replacement Considerations

Direct substitutes include other AZ9731T5 series parts with matching coil voltages and contact configurations. Verify pinout compatibility when considering cross-brand equivalents. Ensure replacement units maintain the 50 Amp rating and Mini-ISO physical dimensions.
