Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1910555 qualifies as a direct substitute for the 1974957 based on the following critical parameters:

• Electrical Compatibility: Identical current and voltage ratings (12A at 630V IEC; 10A at 300V UL)
• Mechanical Compatibility: Matching pitch (5.00mm), position count (5), wire entry angle (180°), and mounting configuration (free-hanging in-line)
• Termination Compatibility: Identical screwless push-in spring termination style
• Wire Gauge Compatibility: Identical wire gauge range (12-26 AWG / 0.2-2.5mm²)
• Material & Safety Compliance: Matching housing material (Polyamide/Nylon), flammability rating (UL94 V-0), and RoHS compliance

The primary distinction is product status: 1974957 is obsolete while 1910555 is active, with both parts belonging to the Phoenix Contact COMBICON terminal block family.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1910555 is the direct active equivalent for the obsolete 1974957. Both parts maintain identical electrical specifications, mechanical dimensions, and termination characteristics. The 1910555 is recommended for new designs and replacement applications due to its active product status and continuous availability. Both parts carry RoHS compliance and UL94 V-0 flammability certification, meeting current regulatory requirements. The transition from the COMBICON FKCS series (1974957) to the COMBICON FKC series (1910555) represents a product line consolidation within Phoenix Contact's terminal block portfolio, with no functional or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the 1910555 directly replace the 1974957 in existing installations?

A: Yes. The 1910555 is mechanically and electrically identical to the 1974957. Both parts feature the same 5-position configuration, 5.00mm pitch, 180° wire entry, push-in spring termination, and electrical ratings (12A at 630V IEC). Physical dimensions and mounting characteristics are equivalent.

Q: What is the primary reason for substitution?

A: The 1974957 is classified as obsolete. The 1910555 is the active Phoenix Contact equivalent, ensuring ongoing availability and supply chain continuity.

Q: Are there any differences in packaging between these parts?

A: The 1974957 is listed with unspecified packaging, while the 1910555 is supplied in bulk packaging. This distinction does not affect functional compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1974957 and 1910555 are RoHS compliant, carry UL94 V-0 flammability ratings, and share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.

Q: What wire gauges are compatible with these terminal blocks?

A: Both parts accept wire gauges from 12-26 AWG (0.2-2.5mm²), supporting a range of conductor sizes for flexible circuit design.

Q: Are there any thermal or environmental limitations?

A: Operating temperature specifications are not provided in the technical data. Both parts carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.
