Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1974944 is based on strict electrical and mechanical parameter matching within the COMBICON terminal block family. The substitute part must satisfy the following criteria:

• 4-position configuration with female sockets
• 0.197" (5.00mm) pitch spacing
• 180° free-hanging in-line orientation
• Screwless push-in spring termination
• Minimum 12A current rating (IEC) and 630V voltage rating (IEC)
• Wire gauge compatibility: 12-26 AWG (0.2-2.5mm²)
• UL94 V-0 flammability rating
• RoHS compliance

The Phoenix Contact 1910542 meets all specified parameters and represents the active equivalent within the COMBICON FKC series, providing direct functional and mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations
