Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1975697 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 (2), termination style (Screw - Rising Cage Clamp), and mounting type (Free Hanging In-Line)
• Physical Dimensions: Consistent screw size (M3) and wire entry orientation (180°)
• Material & Compliance: Polyamide housing with UL94 V-0 flammability rating and RoHS compliance

The substitute part 1777833 meets all these criteria while offering active product status and enhanced features.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1777833 is a direct functional equivalent to the 1975697 across all critical electrical and mechanical parameters. Both components share identical pitch, position count, current/voltage ratings, wire gauge compatibility, and termination methodology within the COMBICON PC series.

The 1777833 offers the advantage of active product status, ensuring continued availability and supply chain reliability. The component maintains full RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The addition of retention latches (non-wire side) on the 1777833 provides enhanced mechanical stability during mating operations.

Minor dimensional variation exists in insulation height (1975697: 0.902" vs. 1777833: 0.776"), which does not affect functional compatibility in standard mounting configurations. Torque specification ranges differ slightly (1975697: 0.7-0.8 Nm vs. 1777833: 0.5-0.8 Nm), with the substitute accommodating the original specification within its lower tolerance band.

Frequently Asked Questions (FAQ)

Q: Can the 1777833 directly replace the 1975697 in existing assemblies?

A: Yes. Both components are electrically and mechanically equivalent across all critical parameters: 2-position configuration, 0.300" pitch, 41A/1 kV rating, 8-24 AWG wire compatibility, and screw-type rising cage clamp termination. Physical mounting and electrical performance remain unchanged.

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

A: The insulation height difference (0.902" vs. 0.776") reflects dimensional refinement in the active design. This does not impact functional compatibility in standard free-hanging in-line applications where the component is not constrained by height-critical mounting geometry.

Q: Does the 1777833 include any functional enhancements?

A: The 1777833 incorporates retention latches on the non-wire side, providing improved mechanical stability during connector mating. This is an enhancement that does not alter electrical performance or compatibility with existing mating connectors.

Q: Are there packaging differences between these parts?

A: The 1975697 was supplied with unspecified packaging, while the 1777833 is available in bulk packaging. This distinction affects procurement and handling but does not influence component performance or substitution eligibility.

Q: What compliance certifications apply to both parts?

A: Both components meet UL94 V-0 flammability requirements, RoHS standards (1975697: RoHS Compliant; 1777833: ROHS3 Compliant), and REACH unaffected status. Both carry identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.

Q: Is the torque specification difference a concern for installation?

A: No. The 1777833 torque range (0.5-0.8 Nm) encompasses the original specification (0.7-0.8 Nm). Installation procedures using the original torque value remain valid and fall within the substitute's acceptable range.
