Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1975736 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 (6), wire entry angle (180°), and termination method (screw-rising cage clamp)
• Physical Form Factor: Free-hanging in-line mounting configuration with identical screw size (M3)
• Material & Safety Compliance: Polyamide housing with UL94 V-0 flammability rating

The substitute part 1777875 meets all these criteria, maintaining full electrical and mechanical interchangeability with the original component.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1777875 is the direct active equivalent for the obsolete 1975736 terminal block plug. Both components are manufactured by Phoenix Contact within the COMBICON PC series and maintain identical electrical ratings, mechanical dimensions, and termination specifications.

Status Transition: The 1975736 is classified as obsolete, while 1777875 holds active product status. For new designs and ongoing procurement, 1777875 is the recommended selection.

Compliance Alignment: Both parts maintain RoHS compliance (1975736: RoHS Compliant; 1777875: ROHS3 Compliant) and REACH unaffected status. The UL94 V-0 flammability rating is preserved across both variants.

Physical Differences: The substitute part features a reduced insulation height (0.776" versus 0.902") and includes retention latches on the non-wire side, which enhance mechanical stability without affecting electrical performance. The torque specification range for 1777875 (0.5-0.8 Nm) encompasses the original specification (0.7-0.8 Nm), ensuring compatibility with existing assembly procedures.

Frequently Asked Questions (FAQ)

Q: Can 1777875 be used as a direct replacement for 1975736 in existing assemblies?

A: Yes. Both components share identical electrical ratings (41A at 1 kV IEC), mechanical pitch (0.300" / 7.62mm), wire gauge compatibility (8-24 AWG), and termination method (screw-rising cage clamp). The reduced insulation height and additional retention latches in 1777875 do not compromise interchangeability.

Q: What is the significance of the insulation height difference?

A: The insulation height difference (0.902" for 1975736 versus 0.776" for 1777875) reflects a design refinement in the active product. This dimensional change does not affect electrical performance or wire gauge capacity and is compatible with standard mounting configurations for free-hanging in-line terminal blocks.

Q: Are the torque specifications compatible?

A: Yes. The 1777875 torque range (0.5-0.8 Nm) overlaps with the 1975736 specification (0.7-0.8 Nm). Assembly procedures using the original 0.7-0.8 Nm range remain valid for the substitute part.

Q: What do the retention latches on 1777875 provide?

A: The retention latches (non-wire side) on 1777875 enhance mechanical stability during mating and unmating cycles. This feature does not alter electrical performance or compatibility with mating connectors.

Q: Is packaging a consideration for substitution?

A: The 1975736 is supplied in standard packaging, while 1777875 is supplied in bulk packaging. Both formats contain identical components; packaging selection depends on procurement volume and inventory management requirements.

Q: Are both parts RoHS compliant?

A: Yes. The 1975736 is RoHS Compliant, and 1777875 is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restrictions.
