Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C93412 is determined by strict alignment with the following core electrical and mechanical parameters:

Critical Matching Parameters:

• Coil voltage: 12VDC
• Contact form: DPDT (2 Form C)
• Contact rating: 2 A minimum
• 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 compliance: ROHS3 Compliant

The V23079A2003B301 satisfies all critical matching parameters. While this substitute is classified as a general-purpose relay rather than a telecom-specific relay, it maintains electrical equivalence across all specified switching and coil characteristics. The substitute part is currently active in production, ensuring availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The V23079A2003B301 is a direct electrical substitute for the obsolete C93412. Both components are manufactured by TE Connectivity Potter & Brumfield Relays and maintain identical coil voltage, contact form, current rating, and switching voltage specifications.

Compliance and Certification Alignment: Both parts are ROHS3 compliant, REACH unaffected, and classified under the same ECCN (EAR99) and HTSUS codes. This ensures regulatory equivalence for procurement and deployment.

Operational Differences: The V23079A2003B301 exhibits lower coil current (11.7 mA versus 25 mA), resulting in reduced power consumption. The substitute part operates at a slightly higher must-operate voltage (9 VDC versus 8.25 VDC) and has a narrower temperature range (-40°C to 85°C versus -55°C to 85°C). Switching times are comparable, with the substitute offering marginally faster operation (4 ms versus 5 ms operate time).

Availability: The V23079A2003B301 is currently active in production with confirmed inventory availability, whereas the C93412 is obsolete. Selection of the substitute part ensures long-term supply chain continuity and eliminates obsolescence risk.

Frequently Asked Questions (FAQ)

Q: Can the V23079A2003B301 directly replace the C93412 in existing designs?

A: Yes. Both relays share identical coil voltage (12VDC), contact form (DPDT), current rating (2A), switching voltage (250VAC/220VDC max), mounting type (through-hole), and termination style (PC pin). Electrical and mechanical compatibility is established.

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

A: The C93412 is classified as a telecom relay, while the V23079A2003B301 is a general-purpose relay. Both are manufactured by TE Connectivity and meet the same electrical specifications. The substitute part features lower coil current consumption (11.7 mA versus 25 mA) and faster operate time (4 ms versus 5 ms).

Q: Are there temperature range limitations with the substitute part?

A: The V23079A2003B301 operates across -40°C to 85°C, compared to the C93412's -55°C to 85°C range. If your application requires operation below -40°C, the substitute part is not suitable. For standard industrial and commercial temperature ranges, the substitute is appropriate.

Q: Does the substitute part meet the same regulatory requirements?

A: Yes. Both the C93412 and V23079A2003B301 are ROHS3 compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8536.41.0020) codes. Regulatory equivalence is confirmed.

Q: What is the packaging difference?

A: The C93412 is supplied with standard packaging, while the V23079A2003B301 is packaged in tubes. This difference does not affect electrical or mechanical performance and is relevant only for handling and storage procedures.

Q: Is the higher must-operate voltage of the substitute part a concern?

A: The V23079A2003B301 requires 9 VDC to operate, compared to 8.25 VDC for the C93412. If your circuit supplies exactly 12VDC nominal coil voltage with typical tolerance margins, this difference is not problematic. Verify your actual supply voltage against the 9 VDC requirement before deployment.

Q: Why is the C93412 obsolete?

A: The C93412 is classified as obsolete by TE Connectivity. The V23079A2003B301 is the active production equivalent, ensuring continued availability and support.
