Engineering Selection Recommendations

The Phoenix Contact 1748943 serves as a direct functional equivalent to the obsolete 1749285. Both components are manufactured by Phoenix Contact within the COMBICON ISPC series and maintain identical electrical ratings, mechanical dimensions, and termination characteristics.

The 1748943 offers the advantage of active product status, ensuring continued availability and support. It carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for new designs and system upgrades. The component is available in bulk packaging with 1022 units in stock.

For applications currently using the 1749285, transition to the 1748943 requires no design modifications. Pin configuration, pitch spacing, wire gauge compatibility, and electrical performance remain unchanged. The only notable design difference is the inclusion of a locking ramp feature on the 1748943, which provides enhanced mechanical retention without affecting electrical or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1748943 directly replace the 1749285 in existing assemblies?

A: Yes. Both components share identical electrical ratings (41A IEC / 35A UL), mechanical pitch (7.62mm), wire gauge compatibility (8-24 AWG), and termination method (screwless push-in spring). No circuit modifications or mechanical redesign is required.

Q: What is the difference between the mating flange on 1749285 and the locking ramp on 1748943?

A: Both features provide mechanical retention during mating. The locking ramp on the 1748943 is a design enhancement that does not affect electrical performance or physical compatibility with corresponding socket components.

Q: Are there packaging differences between these parts?

A: The 1749285 is listed with unspecified packaging, while the 1748943 is supplied in bulk packaging. Both are available in new original condition with full stock availability.

Q: Does the ROHS3 compliance of 1748943 affect compatibility with systems designed for the RoHS-compliant 1749285?

A: No. ROHS3 compliance is a superset of RoHS compliance, indicating enhanced regulatory adherence. The 1748943 is fully compatible with all applications designed for the 1749285.

Q: What is the wire strip length for both components?

A: Both the 1749285 and 1748943 feature a 15mm wire strip length, maintaining consistent preparation requirements for wire termination.

Q: Are both parts suitable for IEC and UL applications?

A: Yes. Both components meet IEC standards (41A, 1kV) and UL standards (35A, 600V), with UL94 V-0 flammability rating for polyamide housing material.
