Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1701757 with part number 1701595 is based on strict equivalence across all critical electrical and mechanical parameters. Both components share identical specifications for:

Position count and pitch (8 positions at 0.400" spacing)
Physical dimensions and panel mounting configuration
Connector type and pin orientation (male pins, right-angle PCB mounting)
Electrical ratings (600 V UL voltage)
Color and feature set (green with threaded mating lock and shield connection)
Compliance certifications (RoHS compliant)

The primary distinction is product status: 1701757 is obsolete while 1701595 is active. The substitute maintains full functional and mechanical interchangeability for direct replacement applications.

Engineering Selection Recommendations

Phoenix Contact 1701595 is the direct substitute for 1701757. Selection is based on the following engineering criteria:

Product Status & Availability: Part 1701757 is obsolete, while 1701595 is active and maintains current manufacturing support. For new designs and ongoing maintenance applications, 1701595 ensures long-term component availability and supply chain continuity.

Electrical & Mechanical Equivalence: Both parts are identical across all specified electrical parameters (600 V UL voltage rating) and mechanical dimensions (8 positions, 0.400" pitch, 4.592" width, right-angle PCB mounting). The snap lock front flange design and threaded mating lock features are preserved.

Compliance & Certification: Both components maintain RoHS compliance and identical ECCN and HTSUS classifications, ensuring regulatory equivalence for applications requiring compliance documentation.

Current Rating Consideration: Part 1701595 features a higher UL current rating (66 A versus 5 A). This represents an enhancement that does not compromise compatibility; applications designed for the original 5 A rating remain fully supported by the substitute.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1701595 be used as a direct replacement for 1701757 in existing assemblies?

A: Yes. Both parts are mechanically and electrically equivalent across all specified parameters. The 1701595 maintains identical pitch, position count, mounting configuration, and connector type. Direct substitution is supported without design modification.

Q: What is the primary reason for substituting 1701757 with 1701595?

A: Part 1701757 is obsolete. Phoenix Contact 1701595 is the active equivalent that provides continued availability, manufacturing support, and supply chain reliability for both new designs and replacement applications.

Q: Are there any electrical rating differences between these parts?

A: The UL voltage rating (600 V) is identical. The UL current rating differs: 1701757 is rated at 5 A while 1701595 is rated at 66 A. The higher current rating of the substitute does not affect compatibility with applications designed for the original part.

Q: Do both parts have the same physical dimensions and mounting requirements?

A: Yes. Width (4.592"), pitch (0.400"), panel thickness range (0.039 ~ 0.118"), and panel mount type (2 piece snap lock front flange) are identical. Both accommodate the same PCB hole spacing and panel cutout dimensions.

Q: Are packaging differences significant for component selection?

A: The main part 1701757 is listed with unspecified packaging, while 1701595 is supplied in bulk packaging. For procurement purposes, confirm packaging requirements with your supplier, but this does not affect functional or mechanical compatibility.

Q: Do both parts support the same mating connector features?

A: Yes. Both components feature threaded mating lock and shield connection on the front side, ensuring identical connector interface compatibility and shielding performance.
