Phoenix Contact 1975794 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1975794 is a 12-position terminal block plug with female sockets, 0.300" (7.62mm) pitch, designed for 180° free-hanging in-line applications. This component features screw-rising cage clamp termination and supports wire gauges from 8-24 AWG (0.2-10mm²). The part is classified as obsolete, making identification of active equivalent components essential for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1975930 qualifies as a direct substitute for the 1975794 based on the following critical parameters:

• Identical electrical specifications: 41A IEC/UL current rating, 1 kV IEC/600V UL voltage rating
• Identical mechanical configuration: 12 positions, 0.300" (7.62mm) pitch, female sockets, 180° free-hanging in-line mounting
• Identical termination method: Screw-rising cage clamp with M3 screw
• Compatible wire gauge range: 8-24 AWG (0.2-10mm²)
• Same series and manufacturer: COMBICON PC series, Phoenix Contact
• Equivalent material and compliance: Polyamide housing, UL94 V-0 flammability rating, RoHS compliant

The primary distinction is product status: 1975794 is obsolete, while 1777930 is active production. The 1777930 includes additional features (retention latches on non-wire side) and minor dimensional variations that do not affect functional compatibility in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1777930 is the direct active production equivalent for the obsolete 1975794. Selection of the 1777930 is based on:

• Product lifecycle alignment: The 1777930 maintains active status with current manufacturing support, ensuring long-term availability and supply chain continuity
• Electrical and mechanical equivalence: All critical performance parameters—current, voltage, pitch, position count, and termination method—are identical
• Compliance maintenance: Both components meet UL94 V-0 flammability requirements and REACH/RoHS standards, with the 1777930 meeting the updated ROHS3 specification
• Functional compatibility: The 1777930 operates within the same electrical and mechanical envelope as the 1975794, supporting identical wire gauge ranges and torque specifications within the specified tolerance band

The 1777930 includes retention latches on the non-wire side and exhibits a reduced insulation height (0.776" versus 0.902"), which do not impact functional substitution in standard terminal block applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1777930 directly replace the 1975794 in existing designs?

A: Yes. The 1777930 maintains identical electrical ratings (41A IEC, 1 kV IEC, 41A UL, 600V UL), mechanical configuration (12 positions, 0.300" pitch), and termination method (screw-rising cage clamp). Both components support 8-24 AWG wire gauges and operate within equivalent performance parameters.

Q: What is the primary reason for substitution?

A: The 1975794 is classified as obsolete. The 1777930 is the active production equivalent from Phoenix Contact's COMBICON PC series, ensuring ongoing availability and manufacturing support.

Q: Are there dimensional differences between these parts?

A: The 1777930 has a reduced insulation height (0.776" versus 0.902") and includes retention latches on the non-wire side. These differences do not affect electrical performance or standard mounting applications.

Q: Do the torque specifications differ?

A: The 1975794 specifies 0.7-0.8 Nm torque, while the 1777930 specifies 0.5-0.8 Nm. The 1777930 range is broader and encompasses the original specification, maintaining compatibility with existing assembly procedures.

Q: Are compliance certifications equivalent?

A: Both components meet UL94 V-0 flammability requirements and REACH standards. The 1777930 carries ROHS3 compliance, representing the current regulatory standard, while the 1975794 carries RoHS compliance. Both are suitable for applications requiring these certifications.

Q: What is the packaging difference?

A: The 1975794 is listed with unspecified packaging, while the 1777930 is supplied in bulk packaging. Confirm packaging requirements with your procurement specification.
