Phoenix Contact 1796157 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1796157 is a 7-position terminal block plug with female sockets, 0.200" (5.08mm) pitch, designed for 180° free-hanging in-line applications. This component features screwless spring cage termination, rated for 12A at 630V, and accommodates wire gauges from 12-24 AWG (0.2-2.5mm²). The part is currently obsolete, making substitute identification critical for ongoing system maintenance and component procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1796157 is determined by strict equivalence across the following critical parameters:

Series compatibility: COMBICON FKC
Position count: 7 positions
Pitch specification: 0.200" (5.08mm)
Connector type: Plug with female sockets
Mounting configuration: Free hanging (in-line)
Wire entry angle: 180°
Termination method: Screwless spring cage
Electrical ratings: 12A at 630V minimum
Wire gauge accommodation: 12-24 AWG (0.2-2.5mm²)
Material compliance: UL94 V-0, RoHS compliant

The Phoenix Contact 1796047 meets all substitution criteria as an active product within the same COMBICON FKC series, maintaining identical electrical, mechanical, and compliance specifications.

Engineering Selection Recommendations

The Phoenix Contact 1796047 is the direct substitute for the obsolete 1796157. Both components are manufactured by Phoenix Contact within the COMBICON FKC series and maintain identical electrical specifications, mechanical dimensions, and compliance certifications. The 1796047 is currently in active production status, ensuring long-term availability and supply chain continuity.

The primary distinction between the two parts is product lifecycle status: the 1796157 is obsolete while the 1796047 remains active. Both components carry UL94 V-0 flammability certification and RoHS compliance, meeting equivalent regulatory requirements. The 1796047 includes a mating flange feature not present in the 1796157, which provides additional mechanical stability in applications requiring enhanced connector retention.

For new designs or system replacements, the 1796047 is the appropriate selection. For legacy system maintenance where the 1796157 was originally specified, the 1796047 provides direct functional equivalence without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 1796047 directly replace the 1796157 in existing installations?

A: Yes. Both components share identical electrical ratings (12A, 630V), mechanical pitch (5.08mm), position count (7), wire gauge accommodation (12-24 AWG), and termination method (screwless spring cage). The 1796047 is mechanically and electrically interchangeable with the 1796157.

Q: What is the significance of the mating flange feature on the 1796047?

A: The mating flange on the 1796047 provides mechanical alignment and retention enhancement during connector mating. This feature does not affect electrical performance or compatibility but improves mechanical stability in applications with frequent connection cycles.

Q: Are there packaging differences between these parts?

A: The 1796157 is listed with unspecified packaging, while the 1796047 is supplied in bulk packaging. Both components are identical in form, fit, and function. Packaging differences do not affect component performance or substitution eligibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1796157 and 1796047 are UL94 V-0 rated, RoHS compliant, and carry identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.

Q: Why is the 1796157 obsolete if the 1796047 is functionally identical?

A: Product obsolescence reflects manufacturing lifecycle decisions by Phoenix Contact. The 1796047 represents the current production variant within the COMBICON FKC series. Obsolescence does not indicate technical deficiency but rather a transition to the active product line.
