Engineering Selection Recommendations

The C93424 is classified as an obsolete product. The substitute part identified (C93424) is parametrically identical across all electrical, mechanical, and compliance specifications. This substitute maintains full compatibility with existing circuit designs and system requirements.

Compliance Considerations:

• Both the main part and substitute are ROHS3 compliant, satisfying environmental regulatory requirements for electronic components in restricted substance applications.
• REACH unaffected status confirms compliance with chemical substance regulations.
• Moisture Sensitivity Level 1 (Unlimited) indicates no special moisture control requirements during storage, handling, or assembly.

Functional Continuity:

• Identical coil voltage (12VDC), contact form (DPDT), and current rating (2A) ensure direct functional replacement.
• Matching switching voltage limits (250VAC, 220VDC maximum) and timing characteristics (5ms operate, 3ms release) preserve system performance.
• Through-hole mounting with PC pin termination maintains mechanical compatibility with existing PCB layouts.

Inventory & Availability:

• 1078 pieces of the substitute part are available as new original stock, supporting immediate procurement for replacement and new production requirements.

Frequently Asked Questions (FAQ)

Q: Is the C93424 substitute part a direct replacement for the obsolete C93424 main part?

A: Yes. The substitute part is parametrically identical to the main part across all electrical, mechanical, and compliance specifications. It functions as a direct replacement without circuit modification or design alteration.

Q: What parameters must match for a telecom relay to be considered an equivalent substitute?

A: Critical matching parameters include coil voltage (12VDC), contact form (DPDT), contact rating (2A), switching voltage limits (250VAC, 220VDC maximum), coil current (33.3mA), coil resistance (360 Ohms), operating voltage thresholds (7.8VDC must operate, 1.2VDC must release), timing characteristics (5ms operate, 3ms release), operating temperature range (-55°C to 85°C), mounting type (through hole), and termination style (PC pin).

Q: Does the substitute part maintain the same contact material composition?
