Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1975752 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Current rating (41A IEC), voltage rating (1 kV IEC), and wire gauge range (8-24 AWG / 0.2-10mm²) must match exactly
• Mechanical Compatibility: 8-position configuration, 0.300" (7.62mm) pitch, 180° wire entry, and free-hanging in-line mounting must be identical
• Termination Method: Screw-type rising cage clamp termination is required
• Material & Safety: Polyamide housing with UL94 V-0 flammability rating and M3 screw specification must be maintained
• Regulatory Compliance: RoHS and REACH status must be equivalent or superior

The substitute part 1777891 meets all these criteria while offering active product status and enhanced features.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1777891 is a direct functional equivalent to the 1975752 and is suitable for substitution in all applications where the original part was specified. Key advantages of selecting 1777891 include:

• Active Product Status: 1777891 is actively manufactured and supported, ensuring long-term availability and supply chain continuity
• Enhanced Compliance: ROHS3 certification provides superior regulatory alignment compared to the obsolete part's RoHS Compliant status
• Additional Features: Retention latches on the non-wire side provide improved mechanical stability during mating operations
• Identical Electrical Performance: All current, voltage, and wire gauge specifications are maintained
• Mechanical Interchangeability: Pitch, position count, termination method, and mounting configuration are identical

The torque specification range for 1777891 (0.5-0.8 Nm) encompasses the original part's range (0.7-0.8 Nm), ensuring compatibility with existing assembly procedures. The insulation height difference (0.776" vs. 0.902") reflects design optimization in the active product line and does not affect functional compatibility in standard applications.

Frequently Asked Questions (FAQ)

Q: Can 1777891 be used as a direct replacement for 1975752 in existing designs?

A: Yes. Both parts share identical electrical ratings (41A at 1 kV IEC), mechanical configuration (8 positions at 7.62mm pitch), termination method (screw rising cage clamp), and wire gauge compatibility (8-24 AWG). The 1777891 is fully interchangeable from an electrical and mechanical standpoint.

Q: What is the significance of the insulation height difference between these parts?

A: The insulation height difference (0.902" for 1975752 vs. 0.776" for 1777891) reflects design refinement in the active product. This dimensional change does not affect electrical performance or standard mounting applications. Verify clearance in space-constrained installations.

Q: Why does 1777891 have retention latches while 1975752 does not?

A: Retention latches on the non-wire side of 1777891 provide enhanced mechanical stability during connector mating and unmating cycles. This is a design improvement in the active product line and does not affect electrical compatibility.

Q: Are the torque specifications compatible between these parts?

A: The torque range for 1777891 (0.5-0.8 Nm) overlaps with 1975752 (0.7-0.8 Nm). Existing assembly procedures using torque values within 0.7-0.8 Nm are directly applicable to 1777891 without modification.

Q: What is the packaging difference, and does it affect component selection?

A: 1975752 is supplied with unspecified packaging, while 1777891 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical performance. Select based on procurement and inventory requirements.

Q: Is 1777891 compliant with current regulatory standards?

A: Yes. 1777891 carries ROHS3 certification and REACH Unaffected status, meeting current regulatory requirements. The obsolete 1975752 carries RoHS Compliant status, which is superseded by ROHS3 in 1777891.
