Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1975732 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Current rating (41A IEC), voltage rating (1 kV IEC), and wire gauge support (8-24 AWG / 0.2-10mm²) must match or exceed the original specification
• Mechanical Compatibility: 5-position configuration, 0.300" (7.62mm) pitch, 180° wire entry orientation, and screw-type rising cage clamp termination must be identical
• Physical Form Factor: Free-hanging in-line mounting type and M3 screw size must be maintained
• Material and Safety Standards: Polyamide housing with UL94 V-0 flammability rating and equivalent certifications (RoHS, REACH) must be present

The substitute part Phoenix Contact 1777862 meets all these criteria while offering active product status and enhanced features.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1777862 is a direct functional equivalent to the 1975732 and is the appropriate selection for applications requiring this terminal block configuration. Key considerations:

Product Status: The 1975732 is obsolete, while the 1777862 maintains active product status with ongoing manufacturer support and availability. This ensures long-term supply chain reliability and access to technical documentation.

Compliance and Certifications: Both parts maintain equivalent electrical safety certifications (UL94 V-0 flammability rating, 1 kV IEC voltage rating, 41A current rating). The 1777862 carries ROHS3 compliance, representing current regulatory alignment.

Physical and Electrical Equivalence: All critical parameters—pitch, wire entry angle, termination method, wire gauge support, and screw specifications—are identical between the two parts, ensuring direct mechanical and electrical interchangeability.

Additional Features: The 1777862 includes retention latches on the non-wire side, providing enhanced mechanical security during mating operations. This represents a functional improvement without introducing incompatibility.

Dimensional Variation: The insulation height differs between parts (1975732: 0.902" / 22.90mm; 1777862: 0.776" / 19.70mm). This dimensional change must be evaluated within the specific application context to ensure clearance compatibility.

Torque Specification: The 1777862 specifies a torque range of 0.5-0.8 Nm, compared to the 1975732 range of 0.7-0.8 Nm. The lower minimum torque value in the substitute part does not compromise connection integrity and provides operational flexibility.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1777862 be used as a direct replacement for the 1975732?

A: Yes. Both parts are 5-position terminal blocks with 0.300" (7.62mm) pitch, identical electrical ratings (41A IEC, 1 kV IEC), matching wire gauge support (8-24 AWG), and equivalent screw-type rising cage clamp termination. Electrical and mechanical compatibility is confirmed across all critical parameters.

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

A: The 1975732 has an insulation height of 0.902" (22.90mm), while the 1777862 measures 0.776" (19.70mm). This 0.126" (3.20mm) reduction must be evaluated within your specific application layout to confirm adequate clearance and mounting compatibility. No functional electrical impact results from this dimensional change.

Q: Are there any differences in wire termination capability?

A: Both parts support identical wire gauge ranges (8-24 AWG / 0.2-10mm²) and use the same M3 screw-type rising cage clamp termination method. The torque specification for the 1777862 (0.5-0.8 Nm) encompasses the original specification range (0.7-0.8 Nm), ensuring equivalent connection reliability.

Q: What does the retention latch feature on the 1777862 provide?

A: The 1777862 includes retention latches on the non-wire side, which enhance mechanical security during mating and unmating operations. This feature does not affect electrical performance or compatibility with existing connector housings.

Q: How do the compliance certifications compare?

A: Both parts meet UL94 V-0 flammability requirements and maintain REACH unaffected status. The 1777862 carries ROHS3 compliance, representing alignment with current regulatory standards, while the 1975732 carries RoHS compliant status. Both are suitable for applications requiring these certifications.

Q: Is the 1777862 available in the same packaging as the 1975732?

A: The 1975732 was supplied in standard packaging, while the 1777862 is available in bulk packaging. Confirm bulk packaging compatibility with your procurement and assembly processes.

Q: Why is the 1975732 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this part number. The 1777862 represents the active equivalent, ensuring access to current inventory, technical support, and long-term supply chain continuity.
