Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1975765 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of positions: 9
• Pitch: 0.300" (7.62mm)
• Type: Plug, Female Sockets
• Plug wire entry orientation: 180°
• Termination style: Screw - Rising Cage Clamp
• Mounting type: Free Hanging (In-Line)
• Current rating (IEC): 41A
• Voltage rating (IEC): 1 kV
• Wire gauge range: 8-24 AWG (0.2-10mm²)
• Housing material: Polyamide (PA), Nylon
• Flammability rating: UL94 V-0
• Screw size: M3
• Series: COMBICON PC

The substitute part 1777901 meets all mandatory matching parameters and is classified as active product status, making it a direct functional equivalent for the obsolete 1975765.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1777901 is the direct substitute for the obsolete 1975765. Both components are manufactured by Phoenix Contact within the COMBICON PC series and maintain identical electrical and mechanical specifications across all critical parameters.

Product Status Consideration: The 1975765 is classified as obsolete, while the 1777901 is active. For new designs, ongoing production, or system maintenance requiring component replacement, the 1777901 should be specified.

Compliance Status: The 1777901 carries ROHS3 compliance certification, representing current regulatory alignment. The 1975765 carries RoHS compliance. Both components maintain UL94 V-0 flammability rating and EAR99 export classification.

Physical Differences: The 1777901 includes retention latches on the non-wire side and features a torque range of 0.5-0.8 Nm compared to the 1975765 torque range of 0.7-0.8 Nm. The insulation height differs: 1777901 measures 0.776" (19.70mm) versus 1975765 at 0.902" (22.90mm). These dimensional variations do not affect functional compatibility in standard mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1777901 directly replace the 1975765 in existing installations?

A: Yes. Both components share identical electrical ratings (41A at 1 kV IEC), mechanical pitch (0.300"/7.62mm), termination method (screw-rising cage clamp), and wire gauge compatibility (8-24 AWG). The 1777901 is functionally equivalent for all standard applications.

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

A: The 1777901 has a reduced insulation height of 0.776" (19.70mm) compared to the 1975765 at 0.902" (22.90mm). This dimensional change does not affect electrical performance or standard mounting compatibility. Verify clearance in space-constrained applications.

Q: Why does the 1777901 include retention latches while the 1975765 does not?

A: The retention latches on the 1777901 (non-wire side) represent a design enhancement in the active product line. This feature improves mechanical stability during mating operations and does not affect compatibility with standard connector housings.

Q: Are there packaging differences between these parts?

A: The 1975765 is listed with unspecified packaging, while the 1777901 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What compliance certifications apply to both parts?

A: Both components are UL94 V-0 rated, EAR99 classified, and carry MSL 1 (unlimited moisture sensitivity level). The 1777901 carries ROHS3 compliance; the 1975765 carries RoHS compliance. Both meet current regulatory requirements for their respective product statuses.

Q: Is the torque specification difference between 0.7-0.8 Nm and 0.5-0.8 Nm significant?

A: The 1777901 torque range of 0.5-0.8 Nm provides greater flexibility in screw tightening procedures. The overlapping upper limit (0.8 Nm) ensures compatibility with existing assembly specifications. Standard termination practices remain unchanged.
