Key Parameters

Substitute Part Grouping Explanation

Substitution of the C93432 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Coil Voltage: 12VDC
• Contact Form: DPDT (2 Form C)
• Contact Rating (Current): 2 A
• Switching Voltage: 250VAC, 220VDC - Max
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Coil Type: Non Latching
• Contact Material: Silver Nickel (AgNi), Gold (Au)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The V23079A2003B301 satisfies all mandatory matching parameters, establishing it as a direct functional equivalent. Both components operate within the same electrical specifications and physical constraints, enabling direct substitution in applications requiring DPDT relay functionality at 12VDC with 2A contact capacity.

Parameter Comparison

Engineering Selection Recommendations

The V23079A2003B301 is the direct substitute for the obsolete C93432. Selection of this substitute is based on the following engineering criteria:

Product Status: The C93432 is obsolete with no continued manufacturing. The V23079A2003B301 maintains active product status with confirmed inventory availability (1900 pcs), ensuring long-term supply chain continuity.

Functional Equivalence: Both components share identical electrical specifications across all critical parameters: 12VDC coil voltage, DPDT contact configuration, 2A contact rating, and 250VAC/220VDC maximum switching voltage. Through-hole mounting and PC pin termination are identical, enabling direct board-level replacement without layout modifications.

Compliance Certifications: Both components are ROHS3 compliant and carry EAR99 ECCN classification. The V23079A2003B301 provides defined REACH status (REACH Unaffected), whereas the C93432 lists vendor-undefined REACH status. This represents an improvement in regulatory documentation clarity.

Operating Characteristics: The V23079A2003B301 exhibits lower coil current (11.7 mA versus 45.8 mA) and higher coil resistance (1.03 kOhms versus 280 Ohms), resulting in reduced power consumption. Operating and release times are comparable (4 ms operate, 4 ms release versus 5 ms operate, 3 ms release). The substitute operates across -40°C to 85°C, which covers the upper portion of the main part's -55°C to 85°C range. Applications requiring operation below -40°C require evaluation of the reduced lower temperature limit.

Frequently Asked Questions (FAQ)

Q: Can the V23079A2003B301 directly replace the C93432 in existing designs?

A: Yes. Both components share identical coil voltage (12VDC), contact configuration (DPDT), contact rating (2A), switching voltage (250VAC/220VDC), mounting type (through-hole), and termination style (PC pin). Direct substitution is supported without circuit modifications.

Q: What are the differences in coil characteristics between these relays?

A: The V23079A2003B301 operates at 11.7 mA coil current with 1.03 kOhms resistance, compared to the C93432 at 45.8 mA and 280 Ohms. The substitute requires lower drive current, reducing power dissipation in the coil circuit. The must-operate voltage differs slightly (9 VDC versus 7.8 VDC), requiring verification that the application supply voltage accommodates this specification.

Q: Are there temperature range limitations with the substitute?

A: The V23079A2003B301 operates from -40°C to 85°C, whereas the C93432 operates from -55°C to 85°C. Applications requiring operation below -40°C must evaluate whether the reduced lower temperature limit is acceptable for the intended environment.

Q: Do both relays use identical contact materials?

A: Yes. Both components feature Silver Nickel (AgNi) and Gold (Au) contact materials, ensuring equivalent contact performance and switching characteristics across the specified voltage and current ranges.

Q: What is the packaging format for both components?

A: Both the C93432 and V23079A2003B301 are supplied in tube packaging, maintaining consistency in handling, storage, and automated assembly processes.

Q: Are there regulatory compliance differences between these parts?

A: Both components are ROHS3 compliant and carry EAR99 ECCN classification. The V23079A2003B301 provides explicit REACH Unaffected status, whereas the C93432 lists vendor-undefined REACH status. For applications requiring documented REACH compliance, the V23079A2003B301 offers clearer regulatory documentation.

Q: What is the inventory status for the substitute part?

A: The V23079A2003B301 is actively manufactured with 1900 pcs confirmed in stock, providing reliable supply availability for new designs and production requirements.
