Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1974931 is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Current rating (12A IEC / 10A UL) and voltage rating (630V IEC / 300V UL) must be maintained
• Physical Configuration: 3-position count, 0.197" (5.00mm) pitch, and 180° free-hanging in-line orientation are non-negotiable
• Termination Method: Screwless push-in spring termination with leg spring contact design
• Wire Compatibility: Support for 12-26 AWG (0.2-2.5mm²) wire gauge range
• Compliance Standards: RoHS compliance and UL94 V-0 flammability rating

The substitute part 1910539 maintains full equivalence across all these parameters while offering active product status and improved compliance documentation.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1910539 is the direct active equivalent for the obsolete 1974931 model. Both components are manufactured by Phoenix Contact and maintain identical electrical ratings, physical dimensions, and termination characteristics across all specified parameters.

The 1910539 offers the advantage of active product status, ensuring continued availability and support. The upgrade from RoHS Compliant to ROHS3 Compliant status on the substitute part reflects current regulatory alignment without affecting functional compatibility.

For applications currently using the 1974931, direct substitution with the 1910539 is supported without design modification or re-qualification, provided the application requirements remain within the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the 1910539 directly replace the 1974931 in existing designs?

A: Yes. Both parts maintain identical electrical ratings (12A at 630V IEC), physical configuration (3-position, 5.00mm pitch, 180° orientation), termination method (screwless push-in spring), and wire gauge compatibility (12-26 AWG). No design changes are required.

Q: What is the difference between the COMBICON FKCS and COMBICON FKC series designations?

A: The series designation change reflects Phoenix Contact's product line evolution. The FKC series represents the current active generation, while FKCS is the obsolete predecessor. Functional and electrical specifications remain equivalent.

Q: Are there packaging differences between these parts?

A: The 1974931 is listed with unspecified packaging, while the 1910539 is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Does the ROHS3 compliance on the 1910539 affect compatibility?

A: No. ROHS3 compliance is a regulatory status upgrade that does not alter the component's electrical or mechanical characteristics. It reflects alignment with current environmental standards.

Q: What wire gauges are supported by both parts?

A: Both the 1974931 and 1910539 support 12-26 AWG wire gauge range, equivalent to 0.2-2.5mm² cross-sectional area.

Q: Are both parts suitable for the same voltage and current applications?

A: Yes. Both parts are rated for 12A at 630V (IEC) and 10A at 300V (UL), making them suitable for identical electrical applications within these specifications.
