Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1910571 qualifies as a direct substitute for the 1974973 based on the following critical parameters:

• Electrical Ratings: Identical current (12A IEC, 10A UL) and voltage (630V IEC, 300V UL) specifications
• Physical Configuration: Matching 7-position count, 0.197" (5.00mm) pitch, and 180° free-hanging in-line orientation
• Termination Method: Identical screwless push-in spring termination style
• Wire Compatibility: Same wire gauge range (12-26 AWG / 0.2-2.5mm²)
• Material & Safety: Identical UL94 V-0 flammability rating, polyamide housing, and tin contact finish
• Compliance: Both parts are RoHS compliant with MSL 1 rating

The primary distinction is product status: the 1974973 is obsolete while the 1910571 is active, and series designation differs (COMBICON FKCS versus COMBICON FKC).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1910571 is the direct functional equivalent for the obsolete 1974973. All electrical, mechanical, and material specifications are identical. The 1910571 carries active product status and maintains full RoHS compliance with UL94 V-0 flammability certification, making it suitable for direct substitution in applications currently using the 1974973.

Selection of the 1910571 eliminates obsolescence risk while preserving all performance characteristics and safety certifications of the original design.
