Phoenix Contact 1975600 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1975600 is a 4-position terminal block plug with female sockets, 0.300" (7.62mm) pitch, designed for 180° free-hanging in-line applications. This component features screw-type rising cage clamp termination and supports wire gauges from 8-24 AWG (0.2-10mm²). The part is classified as obsolete, making identification of active equivalent models essential for procurement and system continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1975600 is determined by strict equivalence across the following critical parameters:

• Manufacturer and series consistency (Phoenix Contact COMBICON PC)
• Identical position count (4 positions)
• Matching pitch specification (0.300" / 7.62mm)
• Identical connector type (Plug with female sockets)
• Matching mounting configuration (Free hanging, in-line orientation)
• Identical wire entry angle (180°)
• Equivalent termination method (Screw-type rising cage clamp)
• Electrical ratings meeting or exceeding original specifications (41A IEC, 1 kV IEC)
• Compatible wire gauge acceptance (8-24 AWG minimum)
• Housing material and flammability compliance (UL94 V-0)

The Phoenix Contact 1777749 meets all substitution criteria as an active product variant within the same COMBICON PC series.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1777749 is the direct active equivalent for the obsolete 1975600 model. Both components maintain identical electrical specifications, mechanical configuration, and termination characteristics within the COMBICON PC series.

The 1777749 offers the advantage of active product status, ensuring ongoing availability and supply chain continuity. The component carries ROHS3 compliance, representing current regulatory alignment compared to the RoHS compliance designation of the 1975600.

The insulation height differential (0.902" versus 0.776") reflects a design refinement in the active variant. This dimensional change does not affect functional compatibility in standard mounting applications where the connector is positioned as a free-hanging in-line element.

Torque specification for the 1777749 screw termination ranges from 0.5-0.8 Nm, compared to 0.7-0.8 Nm for the 1975600. The lower minimum torque value in the active variant provides equivalent clamping performance across the specified range.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1777749 directly replace the 1975600 in existing assemblies?

A: Yes. Both components share identical electrical ratings (41A IEC, 1 kV IEC), mechanical pitch (0.300" / 7.62mm), position count (4), wire gauge acceptance (8-24 AWG), and termination method (screw-type rising cage clamp). The 1777749 is functionally equivalent for all standard applications.

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

A: The 1975600 has an insulation height of 0.902" (22.90mm), while the 1777749 measures 0.776" (19.70mm). This dimensional refinement in the active variant does not affect electrical performance or standard mounting configurations. Physical clearance should be verified in space-constrained applications.

Q: Are there packaging differences between these components?

A: The 1975600 is supplied with unspecified packaging, while the 1777749 is available in bulk packaging. Both maintain identical electrical and mechanical specifications. Packaging selection should be based on procurement volume and handling requirements.

Q: What regulatory compliance differences exist between the two parts?

A: The 1975600 carries RoHS compliance certification, while the 1777749 is ROHS3 compliant, representing alignment with current regulatory standards. Both components maintain REACH Unaffected status and EAR99 export classification. The 1777749 reflects current compliance requirements for new designs.

Q: Is the torque specification change between parts significant?

A: The 1975600 specifies 0.7-0.8 Nm screw torque, while the 1777749 allows 0.5-0.8 Nm. The lower minimum torque in the active variant provides equivalent clamping force across the specified range. Standard termination procedures remain unchanged.

Q: Why is the 1975600 classified as obsolete?

A: The 1975600 has been superseded by the 1777749 within the COMBICON PC series. The active variant incorporates design refinements and current regulatory compliance. Procurement should transition to the 1777749 for new applications and ongoing supply assurance.
