AZ9731T5-1C-24DC2ED2

Relay Automotive Overview

The AZ9731T5-1C-24DC2ED2 is a 50 Amp Mini-ISO automotive relay from the American Zettler AZ9731T5 series. It features a 24VDC coil with 360 Ohm resistance and SPDT (1 Form C) contacts. The switchable current rating is 50A for normally open and 40A for normally closed configurations, supporting up to 75VDC. Operating temperature ranges from -40°C to 125°C. Mechanical life expectancy is 1x10^7 operations, while electrical life is 1x10^5 at rated load. Actuation time is 10ms maximum.

Relay Automotive Feature Summary

• High current capacity of 50 Amps for demanding automotive loads
• Extended operating temperature range suitable for harsh environments
• SPDT contact configuration providing flexible circuit control

Relay Automotive Applications

• Automotive high-current switching applications
• Industrial power distribution systems
• Heavy-duty equipment control circuits

Relay Automotive Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm coil voltage, contact form, and terminal style match the design requirements. Ensure the Mini-ISO footprint compatibility with the target PCB or chassis mount bracket. Cross-reference the 50A rating with actual load profiles to prevent derating issues under continuous operation conditions.

Relay Automotive Selection Notes

Select this component when a 50A switching capacity is required in a Mini-ISO form factor. The 24VDC coil specification suits standard vehicle electrical architectures. Consider the SPDT arrangement if both normally open and normally closed functions are needed within a single package. Validate thermal management capabilities given the 125°C upper limit.

Relay Automotive Part Context

This part belongs to the AZ9731T5 series, an evolution of the AZ9731 family designed for higher current handling. It utilizes the Mini-ISO standard interface, ensuring interchangeability with other components in the same connector ecosystem. The T5 designation typically indicates enhanced performance characteristics compared to base models.

Relay Automotive Replacement Considerations

Direct substitutes include the AZ9731-1C-24DC2ED2, though it offers a lower 40A rating. For identical 50A specifications, verify availability of other AZ9731T5 variants with matching coil and contact parameters.
