Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity Potter & Brumfield Relays 1-1422025-0 is the designated manufacturer-recommended substitute for the obsolete C93435. Both components are manufactured by TE Connectivity Potter & Brumfield Relays and share identical electrical specifications for coil voltage, contact form, contact rating, switching voltage, coil type, and termination style.

The substitute part 1-1422025-0 provides the following advantages:

Product Status: The substitute maintains active manufacturing status, ensuring long-term component availability and supply chain continuity compared to the obsolete C93435.

Regulatory Compliance: The main part C93435 carries ROHS3 Compliant and REACH Unaffected certifications. Selection of the manufacturer-recommended substitute ensures compliance alignment with original design specifications.

Electrical Performance: The substitute exhibits lower coil current (5.8 mA versus 12.5 mA), which reduces power consumption in the control circuit. Higher coil resistance (4.114 kOhms versus 2.06 kOhms) in the substitute reflects this improved efficiency characteristic.

Operating Temperature: 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 require evaluation against specific environmental requirements.

Mechanical Compatibility: Both components feature identical through-hole mounting and PC pin termination, enabling direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the 1-1422025-0 directly replace the C93435 in existing circuit designs?

A: Yes. Both components share identical coil voltage (24VDC), contact form (DPDT), contact rating (2A), switching voltage (250VAC/220VDC), and termination style (PC Pin). Through-hole mounting is identical, permitting direct substitution without circuit board redesign.

Q: What is the significance of the different coil current specifications?

A: The substitute part 1-1422025-0 draws 5.8 mA compared to the main part's 12.5 mA. This lower coil current reflects improved design efficiency and reduces power consumption in the control circuit. Existing drive circuits rated for 12.5 mA operation will function correctly with the lower current requirement.

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

A: The substitute 1-1422025-0 operates from -40°C to 85°C, while the main part C93435 operates from -55°C to 85°C. Applications requiring operation below -40°C must retain the original C93435 specification or identify alternative components rated for extended low-temperature operation.

Q: What is the difference in coil resistance between these parts?

A: The substitute 1-1422025-0 has a coil resistance of 4.114 kOhms compared to the main part's 2.06 kOhms. This higher resistance, combined with lower coil current, indicates improved efficiency. The resistance difference does not affect functional compatibility in standard 24VDC relay drive circuits.

Q: Is the substitute part available in the same packaging format?

A: The main part C93435 is specified with dash packaging, while the substitute 1-1422025-0 is supplied in tube packaging. Both employ identical PC pin termination and through-hole mounting, ensuring mechanical compatibility regardless of packaging format.

Q: Why is the C93435 classified as obsolete?

A: The C93435 is an obsolete product from the MT2 AXICOM series. The manufacturer-recommended substitute 1-1422025-0 from the V23079 AXICOM series provides equivalent functionality with active manufacturing status and improved design characteristics.

Q: Are regulatory certifications maintained with the substitute part?

A: The main part C93435 carries ROHS3 Compliant and REACH Unaffected certifications. The manufacturer-recommended substitute 1-1422025-0 is designated as the equivalent replacement, ensuring regulatory compliance alignment with original design specifications.

Q: What are the operate and release time differences?

A: The main part C93435 has operate time of 5 ms and release time of 3 ms. The substitute 1-1422025-0 has operate time of 4 ms and release time of 4 ms. Both timing specifications fall within typical telecom relay performance ranges and do not affect functional compatibility in standard applications.
