Substitute Part Grouping Explanation

The Phoenix Contact 1777752 qualifies as a direct substitute for the 1975613 based on the following critical parameters:

Identical number of positions (5) and pitch spacing (0.300"/7.62mm)
Matching connector type (plug with female sockets)
Same mounting configuration (free hanging, in-line, 180° wire entry)
Identical termination method (screw-type rising cage clamp)
Equivalent electrical ratings (41A IEC, 1 kV IEC; 41A UL, 600V UL)
Compatible wire gauge range (8-24 AWG / 0.2-10mm²)
Same housing material (Polyamide/Nylon) and flammability rating (UL94 V-0)
Identical screw size (M3) and wire strip length (10mm)

The primary distinction is product status: 1975613 is obsolete while 1777752 is active, making 1777752 the recommended procurement choice for new designs and replacements.

Engineering Selection Recommendations

The Phoenix Contact 1777752 is the direct active equivalent for the obsolete 1975613. Both components share identical electrical specifications, mechanical dimensions (pitch, position count, screw size), and termination characteristics. The 1777752 maintains full compatibility with existing connector housings and mating interfaces designed for the 1975613.

The 1777752 carries ROHS3 compliance, representing current regulatory alignment compared to the 1975613's RoHS Compliant status. Both components maintain REACH Unaffected status and identical MSL ratings. The screw torque specification for 1777752 (0.5-0.8 Nm) encompasses the 1975613 range (0.7-0.8 Nm), ensuring installation compatibility.

The minor difference in insulation height (0.902" versus 0.776") reflects design refinement in the active product line but does not affect electrical or mechanical substitution capability for standard applications.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1777752 directly replace 1975613 in existing assemblies?

A: Yes. Both components are identical in pitch (7.62mm), position count (5), connector type (plug with female sockets), termination method (screw-type rising cage clamp), and electrical ratings (41A IEC, 1 kV IEC). The 1777752 is mechanically and electrically interchangeable with the 1975613.

Q: What is the significance of the product status difference?

A: The 1975613 is classified as obsolete, indicating Phoenix Contact no longer manufactures or supports this part number. The 1777752 is active, meaning it is currently produced and supported. For new designs and long-term procurement, the 1777752 is the appropriate selection.

Q: Are there differences in wire gauge compatibility?

A: No. Both the 1975613 and 1777752 accept wire gauges from 8-24 AWG (0.2-10mm²) with identical screw termination specifications.

Q: How do the screw torque specifications compare?

A: The 1975613 specifies 0.7-0.8 Nm (6.2-7.1 Lb-In), while the 1777752 specifies 0.5-0.8 Nm (4.4-7.1 Lb-In). The 1777752 range is broader and encompasses the 1975613 specification, ensuring compatibility with existing installation procedures.

Q: What is the difference in insulation height?

A: The 1975613 has an insulation height of 0.902" (22.90mm), while the 1777752 measures 0.776" (19.70mm). This dimensional refinement does not affect electrical performance or mechanical substitution in standard terminal block applications.

Q: Are both parts RoHS compliant?

A: Yes. The 1975613 is RoHS Compliant, and the 1777752 is ROHS3 Compliant. Both meet current environmental regulations. The 1777752 reflects the current regulatory standard.

Q: What packaging is available for each part?

A: The 1975613 is supplied in standard packaging. The 1777752 is available in bulk packaging, which may affect procurement quantities and logistics considerations.
