Phoenix Contact 1975707 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1975707 is a 3-position terminal block plug with female sockets, 0.300" (7.62mm) pitch, designed for 180° free-hanging in-line applications. This component features screw-type rising cage clamp termination and supports wire gauges from 8-24 AWG (0.2-10mm²). The part is currently classified as obsolete, making identification of suitable substitutes essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1975707 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Identical current rating (41A IEC), voltage rating (1 kV IEC), and wire gauge range (8-24 AWG / 0.2-10mm²)
• Mechanical Compatibility: Matching pitch (0.300" / 7.62mm), position count (3), wire entry angle (180°), and termination method (screw-type rising cage clamp)
• Physical Form Factor: Free-hanging in-line mounting configuration with identical screw size (M3)
• Material & Compliance: Polyamide housing with UL94 V-0 flammability rating and RoHS compliance

The substitute part 1777846 meets all these criteria, with documented differences limited to product status (active vs. obsolete), packaging format, and minor variations in torque specification and insulation height that do not affect functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1777846 is the direct functional equivalent for the obsolete 1975707. Both components are manufactured by Phoenix Contact within the COMBICON PC series and maintain identical electrical and mechanical specifications across all critical parameters: 3-position configuration, 0.300" pitch, 41A/1 kV rating, and screw-type termination.

The 1777846 is currently in active production status with higher inventory availability (1253 pcs vs. 802 pcs), ensuring supply chain continuity. Both parts carry equivalent compliance certifications: UL94 V-0 flammability rating, RoHS compliance (with 1777846 meeting ROHS3 standard), and REACH unaffected status.

For new designs or system replacements, the 1777846 is the appropriate selection. For legacy system maintenance where the original 1975707 is specified, the 1777846 provides direct substitution without design modification or re-qualification requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1777846 directly replace the 1975707 in existing installations?

A: Yes. Both components share identical electrical ratings (41A, 1 kV), mechanical configuration (3-position, 0.300" pitch, 180° wire entry), and termination method (M3 screw-type rising cage clamp). The housing material, flammability rating, and compliance certifications are equivalent.

Q: What are the differences between these two parts?

A: The primary differences are product status (1975707 is obsolete; 1777846 is active production), packaging format (1975707 standard vs. 1777846 bulk), and minor variations in torque specification (1975707: 0.7-0.8 Nm vs. 1777846: 0.5-0.8 Nm) and insulation height (1975707: 22.90mm vs. 1777846: 19.70mm). These variations do not affect functional interchangeability.

Q: Are there any compatibility concerns with wire gauge or termination?

A: No. Both parts support the identical wire gauge range (8-24 AWG / 0.2-10mm²) and use the same screw-type rising cage clamp termination with M3 screws. Wire strip length is identical at 10mm.

Q: What compliance standards apply to both parts?

A: Both components are UL94 V-0 rated, RoHS compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8536.90.4000. The 1777846 meets the updated ROHS3 standard.

Q: Is the 1777846 available in the same packaging as the 1975707?

A: The 1975707 is supplied in standard packaging, while the 1777846 is available in bulk packaging. Both are in active stock with the 1777846 offering higher inventory levels.
