Phoenix Contact 5451653 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5451653 is a 6-position terminal block plug with female sockets, 0.200" (5.08mm) pitch, and 270° free-hanging in-line mounting. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance. The part features screw termination, tin-plated contacts, and polyamide housing rated UL94 V-0. Substitution is necessary to ensure continued availability and access to components with equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 5451653 is based on strict equivalence of the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 6 positions at 0.200" (5.08mm) pitch for mechanical compatibility with mating connectors
• Socket Type & Orientation: Female socket configuration with 270° free-hanging in-line mounting ensures identical installation geometry
• Electrical Ratings: IEC current rating of 12A and voltage rating of 630V establish the baseline electrical performance envelope
• Wire Compatibility: 12-30 AWG (0.2-2.5mm²) wire gauge range must be maintained for termination compatibility
• Housing & Contact Materials: Polyamide housing with tin-plated contacts and UL94 V-0 flammability rating ensure equivalent environmental and safety performance
• Termination Method: Screw-based termination allows functional substitution

The Phoenix Contact 1834945 qualifies as a direct substitute based on these parameters. While the 1834945 features an enhanced termination style (Rising Cage Clamp) and higher UL current rating (15A vs. 12A), it maintains all critical mechanical and electrical compatibility parameters with the 5451653.

Engineering Selection Recommendations

The Phoenix Contact 1834945 is the qualified substitute for the obsolete 5451653 based on the following engineering criteria:

Product Status & Availability: The 5451653 is classified as obsolete, while the 1834945 maintains active product status with confirmed inventory availability (1129 pcs in stock). This transition ensures long-term procurement viability.

Compliance & Certification: Both parts maintain UL94 V-0 flammability rating and equivalent electrical safety certifications. The 1834945 carries ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. Both parts are classified as EAR99 for export control purposes.

Electrical Performance: The 1834945 meets or exceeds the electrical specifications of the 5451653. While maintaining identical IEC ratings (12A/630V), the 1834945 provides enhanced UL current rating (15A vs. 12A), offering improved performance margin in UL-regulated applications.

Mechanical Compatibility: Identical pitch (5.08mm), position count (6), socket configuration, and mounting geometry ensure direct mechanical substitution without redesign or adapter requirements.

Termination Enhancement: The Rising Cage Clamp termination in the 1834945 provides improved wire retention and contact reliability compared to standard screw termination, with specified torque parameters (0.5-0.6 Nm) and wire strip length (7mm).

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1834945 directly replace the 5451653 in existing applications?

A: Yes. Both parts share identical mechanical dimensions, pitch, position count, socket configuration, and mounting type. The 1834945 maintains equivalent IEC electrical ratings and exceeds UL performance specifications. No circuit redesign or mechanical modification is required.
