  • 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)

Acceptable Variation Parameters:

  • Operating temperature range: Substitute must cover the application's required temperature window
  • Coil current: Variation acceptable if power supply capability is maintained
  • Operate/Release time: Variation acceptable if system timing requirements are met
  • Must Operate/Release voltage: Variation acceptable within system supply tolerance

The V23079A2003B301 meets all critical matching parameters and is classified as an active product with current manufacturing status.

Engineering Selection Recommendations

The V23079A2003B301 is the manufacturer-recommended substitute for the obsolete C93418. Both components are manufactured by TE Connectivity Potter & Brumfield Relays and share identical electrical specifications for coil voltage, contact form, contact rating, and switching voltage.

Compliance Status: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing and deployment.

Product Availability: The C93418 is classified as obsolete with limited inventory (2231 pcs). The V23079A2003B301 is an active product with current manufacturing support and adequate inventory (1900 pcs), providing long-term supply chain continuity.

Electrical Compatibility: The substitute part operates at a higher must-operate voltage (9 VDC versus 7.8 VDC) and exhibits lower coil current (11.7 mA versus 16.7 mA). These variations are within acceptable engineering tolerances for 12VDC supply systems. The substitute's faster operate time (4 ms versus 5 ms) and equivalent release time (4 ms versus 3 ms) are compatible with standard telecom and general-purpose relay applications.

Temperature Consideration: The substitute operates across -40°C to 85°C, compared to the main part's -55°C to 85°C range. Applications requiring operation below -40°C must retain the original C93418 or identify alternative solutions.

Frequently Asked Questions (FAQ)

Q: Can the V23079A2003B301 directly replace the C93418 in existing designs?

A: Yes, for applications operating within the -40°C to 85°C temperature range. Both parts share identical coil voltage (12VDC), contact form (DPDT), contact rating (2A), switching voltage (250VAC/220VDC), mounting type (Through Hole), and termination style (PC Pin). The substitute's higher must-operate voltage (9 VDC) is compatible with standard 12VDC supply systems.

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

A: The C93418 is a telecom-grade relay with extended low-temperature operation (-55°C minimum), while the V23079A2003B301 is a general-purpose relay with a -40°C minimum operating temperature. The substitute exhibits lower coil current consumption (11.7 mA versus 16.7 mA) and higher coil resistance (1.03 kOhms versus 720 Ohms).

Q: Are both parts available for procurement?

A: The C93418 is obsolete with limited remaining inventory. The V23079A2003B301 is an active product with current manufacturing support, making it the recommended choice for new designs and ongoing production.

Q: Do both relays meet current regulatory requirements?

A: Yes. Both the C93418 and V23079A2003B301 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What packaging format is used for both parts?

A: Both relays are supplied in tube packaging with Through Hole mounting and PC Pin termination, maintaining identical mechanical compatibility.

Q: Is the substitute suitable for applications requiring -55°C operation?

A: No. The V23079A2003B301 operates to -40°C minimum. Applications requiring -55°C operation must use the original C93418 or identify alternative relay solutions rated for extended low-temperature performance.

Q: How do the switching characteristics compare?

A: The substitute operates faster (4 ms versus 5 ms) and releases at the same speed (4 ms versus 3 ms). Both relays are non-latching with identical must-release voltage (1.2 VDC), ensuring compatible switching behavior in standard relay circuits.
