Phoenix Contact 5451035 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5451035 is a 9-position terminal block plug with female sockets, 0.200" (5.08mm) pitch, designed for 90° free-hanging in-line applications. This component features screw termination, rated for 12A at 630V (IEC) and 12A at 300V (UL), and accommodates wire gauges from 12-30 AWG (0.2-2.5mm²). The part is classified as obsolete, making equivalent substitutes necessary for ongoing procurement and system maintenance.

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5451035 is determined by strict alignment with the following critical parameters:

Position count and pitch: Must be 9 positions at 0.200" (5.08mm) spacing
Connector type and orientation: Female socket plug with 90° wire entry, free-hanging in-line configuration
Electrical ratings: Minimum 12A at 630V (IEC) and 12A at 300V (UL)
Wire compatibility: Support for 12-30 AWG (0.2-2.5mm²) conductors
Termination interface: Screw-based connection with M3 screw specification
Housing and safety standards: Polyamide construction with UL94 V-0 flammability rating
Mechanical compatibility: Matching screw torque specification (0.5-0.6 Nm)

The Phoenix Contact 1792317 qualifies as a direct substitute based on these parameters. Variations in termination mechanism (rising cage clamp vs. standard screw) and product status (active vs. obsolete) do not affect functional interchangeability when electrical and mechanical specifications align.

Engineering Selection Recommendations

The Phoenix Contact 1792317 is a qualified substitute for the obsolete 5451035 based on complete alignment of electrical, mechanical, and dimensional specifications. The substitute part is currently in active production status with higher inventory availability (1337 pcs vs. 820 pcs), ensuring supply chain continuity.

The 1792317 features an enhanced termination mechanism (rising cage clamp) that maintains full compatibility with the original screw-based interface while providing improved wire retention characteristics. The UL current rating of 15A on the substitute exceeds the original 12A specification, presenting no derating concerns for applications designed around the original part.

Both parts maintain identical RoHS and REACH compliance profiles, with the substitute offering ROHS3 certification. Mechanical compatibility is confirmed through matching M3 screw specifications, torque requirements, and dimensional parameters including insulation height and wire strip length.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1792317 be used as a direct replacement for the 5451035 in existing assemblies?

A: Yes. The 1792317 maintains identical pitch (5.08mm), position count (9), wire entry angle (90°), mounting configuration (free-hanging in-line), and electrical ratings (12A/630V IEC, 12A/300V UL). Mechanical interfaces, including M3 screw specifications and torque requirements, are identical.

Q: What is the difference between the screw termination styles?

A: The 5451035 uses standard screw termination, while the 1792317 incorporates a rising cage clamp mechanism. Both accept M3 screws with identical torque specifications (0.5-0.6 Nm). The rising cage clamp design provides enhanced wire retention without affecting electrical or mechanical compatibility.

Q: Are there packaging differences between these parts?

A: The 5451035 is supplied with unspecified packaging, while the 1792317 is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact functional performance or interchangeability.

Q: Do both parts support the same wire gauge range?

A: Yes. Both the 5451035 and 1792317 accommodate 12-30 AWG (0.2-2.5mm²) conductors with identical 7mm wire strip length specifications.

Q: What is the significance of the higher UL current rating on the 1792317?

A: The 1792317 is rated for 15A at 300V (UL), compared to 12A on the original part. This higher rating does not create compatibility issues; applications designed for the 5451035 operate within the 1792317's electrical envelope.

Q: Are RoHS and REACH compliance requirements met by the substitute?

A: Yes. The 1792317 is ROHS3 compliant and REACH unaffected, meeting or exceeding the RoHS compliance status of the original 5451035. Both parts are suitable for applications requiring environmental compliance certification.
