Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1975710 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 (4), plug wire entry angle (180°), and termination style (screw-type rising cage clamp)
• Physical Form Factor: Free-hanging in-line mounting type with M3 screw size
• Material & Safety: Polyamide housing with UL94 V-0 flammability rating

The substitute part Phoenix Contact 1975710 meets all these criteria while offering active product status and enhanced features.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1777859 is a direct functional equivalent to the obsolete 1975710 terminal block plug. Both components share identical electrical ratings, mechanical specifications, and core design parameters within the COMBICON PC series.

Product Status Advantage: The 1777859 maintains active product status, ensuring long-term availability and continued manufacturer support, whereas the 1975710 is classified as obsolete.

Compliance & Certifications: Both parts meet RoHS and REACH requirements. The 1777859 carries ROHS3 compliance, representing current regulatory alignment. Both maintain UL94 V-0 flammability ratings and identical IEC/UL electrical certifications.

Physical Considerations: The 1777859 features a reduced insulation height (0.776" vs. 0.902") and includes retention latches on the non-wire side as an enhancement. These differences do not affect electrical or mechanical compatibility in standard applications. The torque specification range for the 1777859 (0.5-0.8 Nm) overlaps with the main part (0.7-0.8 Nm), maintaining screw termination compatibility.

Procurement Strategy: For new designs or component replacement, the 1777859 is the recommended selection due to active status and enhanced feature set. Existing inventory of the 1975710 remains functionally equivalent for current applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1777859 directly replace the 1975710 in existing applications?

A: Yes. Both components are electrically and mechanically equivalent across all critical parameters: 4-position configuration, 0.300" (7.62mm) pitch, 41A current rating, 1 kV voltage rating, 8-24 AWG wire gauge support, and screw-type rising cage clamp termination. The 1777859 is suitable for direct substitution.

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

A: The 1777859 has a reduced insulation height (0.776" vs. 0.902"). This dimensional difference does not affect electrical performance or standard mechanical compatibility. Verify clearance in space-constrained applications before implementation.

Q: Does the 1777859 include any additional features compared to the 1975710?

A: The 1777859 includes retention latches on the non-wire side as an enhancement feature. The 1975710 features only the mating flange. This addition improves mechanical retention without affecting electrical specifications or wire termination compatibility.

Q: Are the torque specifications compatible between these parts?

A: The torque ranges overlap. The 1975710 specifies 0.7-0.8 Nm, while the 1777859 specifies 0.5-0.8 Nm. For applications using the 1975710, maintain torque within the 0.7-0.8 Nm range, which is fully supported by the 1777859.

Q: What is the packaging difference between these parts?

A: The 1975710 is listed with no specified packaging designation, while the 1777859 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both components are REACH Unaffected. The 1975710 is RoHS Compliant, and the 1777859 is ROHS3 Compliant, representing current regulatory standards.

Q: Why is the 1975710 classified as obsolete?

A: The 1975710 has reached end-of-life status in the Phoenix Contact product portfolio. The 1777859 represents the active equivalent within the COMBICON PC series, ensuring continued availability and manufacturer support for new procurement.
