Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity Potter & Brumfield Relays 1-1422025-0 is the manufacturer-recommended substitute for the obsolete C93431. Both components are manufactured by TE Connectivity Potter & Brumfield Relays and share identical electrical contact specifications and mechanical mounting characteristics.

The substitute part 1-1422025-0 carries active product status, ensuring ongoing availability and manufacturing support. The C93431 is classified as obsolete, making the 1-1422025-0 the appropriate selection for new designs and component replenishment.

Key differences between the parts include coil current (23 mA versus 5.8 mA), must operate voltage (15.6 VDC versus 18 VDC), operating temperature lower limit (-55°C versus -40°C), and coil resistance (1.05 kOhms versus 4.114 kOhms). These differences reflect design improvements in the substitute part, including reduced power consumption. Circuit designs must accommodate the higher must operate voltage requirement of the substitute component.

Frequently Asked Questions (FAQ)

Q: Can the 1-1422025-0 directly replace the C93431 in existing circuit designs?

A: The 1-1422025-0 maintains identical contact form, current rating, switching voltage, and mounting configuration as the C93431. However, the substitute part requires a minimum operating voltage of 18 VDC compared to 15.6 VDC for the original part. Circuit designs must verify that the coil drive voltage meets or exceeds 18 VDC to ensure proper relay operation.

Q: What are the key electrical differences between these two relay models?

A: The primary electrical differences are coil current (C93431: 23 mA; 1-1422025-0: 5.8 mA), must operate voltage (C93431: 15.6 VDC; 1-1422025-0: 18 VDC), and coil resistance (C93431: 1.05 kOhms; 1-1422025-0: 4.114 kOhms). The substitute part exhibits lower power consumption and faster operate time (4 ms versus 5 ms).

Q: Are the mechanical dimensions and pin configurations identical?

A: Both components feature through-hole mounting with PC pin termination. No dimensional or pinout information is provided in the available specifications. Physical verification is necessary to confirm mechanical compatibility in existing PCB layouts.

Q: What is the operating temperature range difference?

A: The C93431 operates from -55°C to 85°C, while the 1-1422025-0 operates from -40°C to 85°C. Applications requiring operation below -40°C must retain the original C93431 or identify alternative components with extended low-temperature ratings.

Q: Is the substitute part RoHS compliant?

A: The C93431 is ROHS3 compliant. RoHS compliance status for the 1-1422025-0 is not specified in the available documentation.
