TE Connectivity Potter & Brumfield Relays C93403 Equivalent & Substitute Parts

Part Overview

The TE Connectivity Potter & Brumfield Relays C93403 is a telecom relay with DPDT (2 Form C) contact configuration rated for 2A at 24VDC. This component features through-hole mounting with PC pin termination and operates across a temperature range of -55°C to 85°C. The C93403 is classified as obsolete, necessitating identification of equivalent substitute components for ongoing system support and new designs. The substitute part 1-1422025-0 provides functional equivalence with updated product status and maintained electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the C93403 with part number 1-1422025-0 is based on electrical and mechanical parameter equivalence. Both components share identical specifications for coil voltage (24VDC), contact form (DPDT), contact rating (2A), switching voltage (250VAC/220VDC maximum), mounting type (through hole), termination style (PC pin), coil type (non-latching), and contact material composition (Silver Nickel and Gold).

The substitute part maintains compatibility through these critical parameters:

• Identical coil voltage and contact configuration
• Equivalent current and voltage switching ratings
• Matching mechanical form factor and termination interface
• Identical contact material specifications
• Non-latching coil operation

The primary distinction between these components is product status: the C93403 is obsolete while 1-1422025-0 is active, and the substitute operates across a narrower temperature range (-40°C to 85°C versus -55°C to 85°C).

Parameter Comparison

Engineering Selection Recommendations

The C93403 is an obsolete telecom relay. The substitute part 1-1422025-0 is the manufacturer-recommended equivalent and maintains active product status with TE Connectivity Potter & Brumfield Relays.

Both components are manufactured by the same supplier and share identical electrical and mechanical specifications for coil voltage, contact configuration, current rating, switching voltage, mounting interface, and termination style. The substitute part operates with marginally lower coil current (5.8 mA versus 6.3 mA) and slightly faster operate time (4 ms versus 5 ms), representing improved performance characteristics.

The substitute part operates across a reduced temperature range (-40°C to 85°C) compared to the original component (-55°C to 85°C). Applications requiring operation below -40°C must evaluate this temperature specification difference.

The C93403 carries ROHS3 compliance certification. Compliance status for the substitute part 1-1422025-0 is not specified in available documentation.

Frequently Asked Questions (FAQ)

Q: Can part 1-1422025-0 directly replace C93403 in existing designs?

A: Yes. Both components share identical coil voltage (24VDC), contact form (DPDT), current rating (2A), switching voltage (250VAC/220VDC maximum), mounting type (through hole), and PC pin termination. Electrical and mechanical compatibility is established through these matching parameters.

Q: What is the primary difference between these two relays?

A: The C93403 is classified as obsolete while 1-1422025-0 is an active product. The substitute operates across a narrower temperature range (-40°C to 85°C versus -55°C to 85°C). The substitute also exhibits lower coil current consumption (5.8 mA versus 6.3 mA) and faster operate time (4 ms versus 5 ms).

Q: Are there temperature limitations when substituting the C93403?

A: The substitute part 1-1422025-0 operates from -40°C to 85°C. Applications requiring operation below -40°C cannot use this substitute. The original C93403 operates from -55°C to 85°C.

Q: Do both relays have identical contact material specifications?

A: Yes. Both the C93403 and 1-1422025-0 use Silver Nickel (AgNi) and Gold (Au) contact materials.

Q: What is the packaging difference between these parts?

A: The C93403 packaging is not specified. The substitute part 1-1422025-0 is supplied in tube packaging.

Q: Are the coil resistance values identical?

A: No. The C93403 has a coil resistance of 3.87 kOhms while 1-1422025-0 has 4.114 kOhms. This difference correlates with the lower coil current of the substitute part (5.8 mA versus 6.3 mA at 24VDC).

Q: What is the difference in switching speed between these relays?

A: The C93403 operates in 5 ms and releases in 3 ms. The substitute part 1-1422025-0 operates in 4 ms and releases in 4 ms. The substitute exhibits faster operate time and slightly slower release time.

Q: Are both relays RoHS compliant?

A: The C93403 is ROHS3 compliant. RoHS compliance status for substitute part 1-1422025-0 is not specified in available documentation.
