Phoenix Contact 5439264 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5439264 is a 12-position terminal block plug with female sockets, 0.138" (4.60mm) pitch, and 270° free-hanging in-line mounting. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations. The part operates at 8A (IEC/UL) and 320V (IEC) / 300V (UL), supporting wire gauges from 14-30 AWG (0.2-1.5mm²).

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5439264 is determined by strict alignment of the following critical parameters:

• Connector Type & Configuration: 12-position plug with female sockets
• Pitch Specification: 0.138" (4.60mm) center-to-center spacing
• Electrical Ratings: Minimum 8A (IEC) and 320V (IEC) capability
• Wire Gauge Compatibility: Support for 14-30 AWG range
• Mounting Orientation: 270° free-hanging in-line configuration
• Termination Method: Screw-based wire connection
• Housing Material: Polyamide (PA) / Nylon construction
• Compliance Standards: UL94 V-0 flammability rating

The substitute part Phoenix Contact 1862959 meets all critical substitution criteria. Both components share identical pitch, position count, electrical ratings, wire gauge support, mounting type, and housing material specifications. Differences in termination style (rising cage clamp vs. standard screw) and wire strip length represent design enhancements rather than compatibility barriers.

Engineering Selection Recommendations

The Phoenix Contact 1862959 is a direct functional substitute for the obsolete 5439264. Selection should be based on the following engineering factors:

Product Status Consideration: The 5439264 is obsolete with limited inventory availability (768 pcs). The 1862959 is active production status, ensuring long-term supply chain continuity and availability for future procurement cycles.

Compliance & Certification: Both parts maintain UL94 V-0 flammability ratings and equivalent electrical performance (8A/320V IEC). The 1862959 carries ROHS3 compliance versus RoHS compliance on the 5439264, representing enhanced regulatory alignment with current environmental standards.

Termination Technology: The 1862959 incorporates rising cage clamp termination versus standard screw termination on the 5439264. This represents a design enhancement that improves wire retention and reduces installation variability without affecting electrical or mechanical compatibility.

Wire Gauge Capability: The 1862959 supports wire gauges down to 0.14mm² compared to 0.2mm² minimum on the 5439264, providing expanded compatibility with finer gauge conductors within the 14-30 AWG range.

Physical Compatibility: Identical pitch (4.60mm), position count (12), mounting type (270° free-hanging in-line), housing material (Polyamide/Nylon), and insulation height (19.10mm) ensure direct mechanical and electrical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1862959 directly replace the 5439264 in existing installations?

A: Yes. Both components share identical pitch (4.60mm), position count (12), electrical ratings (8A/320V IEC), wire gauge support (14-30 AWG), mounting configuration (270° free-hanging in-line), and housing material (Polyamide/Nylon). Physical and electrical interchangeability is confirmed.

Q: What is the significance of the different termination styles (screw vs. rising cage clamp)?

A: The 1862959 uses rising cage clamp termination, which is a design enhancement that improves wire retention and reduces installation variability. Both termination methods are screw-based and electrically equivalent. The rising cage clamp does not affect compatibility or performance.

Q: Are there any compliance or certification differences between these parts?

A: Both parts maintain UL94 V-0 flammability ratings and equivalent electrical certifications. The 1862959 carries ROHS3 compliance, representing current environmental regulatory alignment, while the 5439264 carries standard RoHS compliance. Both are EAR99 classified and share identical HTSUS codes.

Q: Why does the 1862959 support a lower minimum wire gauge (0.14mm² vs. 0.2mm²)?

A: The 1862959 design accommodates finer gauge conductors within the same 14-30 AWG range. This represents expanded capability and does not affect compatibility with standard wire gauges used with the 5439264.

Q: What is the packaging difference between these parts?

A: The 5439264 is listed with no specified packaging designation, while the 1862959 is supplied in bulk packaging. Both are available as new original stock from Phoenix Contact.

Q: Is the color difference (gray vs. green) significant for substitution?

A: No. Color is a visual identifier only and does not affect electrical, mechanical, or functional compatibility. Both parts are functionally equivalent regardless of housing color.
