Phoenix Contact 5439840 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5439840 is a 9-position terminal block plug with female sockets, 0.200" (5.08mm) pitch, designed for 270° 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 currently obsolete, making equivalent substitutes necessary for ongoing system maintenance and new designs requiring compatible connectivity solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5439840 is determined by the following critical parameters:

• Connector Type & Configuration: Must be a 9-position terminal block plug with female sockets
• Pitch Specification: Must maintain 0.200" (5.08mm) pitch for mechanical compatibility
• Wire Entry Orientation: Must support 270° free-hanging in-line configuration
• Electrical Ratings: Must meet or exceed 12A current and 300V minimum voltage (UL standard)
• Wire Gauge Compatibility: Must accommodate 12-30 AWG (0.2-2.5mm²) wire sizes
• Termination Method: Screw-based termination systems are acceptable
• Compliance: RoHS compliance required for modern applications

The Phoenix Contact 1829604 qualifies as a direct substitute based on these parameters. Both components share identical mechanical form factors, pitch specifications, wire entry orientation, and wire gauge ranges. Electrical ratings remain compatible within UL standards, and both maintain RoHS compliance.

Engineering Selection Recommendations

The Phoenix Contact 1829604 is the qualified substitute for the obsolete 5439840. Selection is based on the following engineering criteria:

Product Status: The 1829604 maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete 5439840.

Compliance & Certification: Both components are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications, meeting regulatory requirements for equivalent component substitution.

Electrical Performance: The 1829604 provides equal or superior electrical ratings. While the IEC voltage rating decreases from 630V to 250V, the UL voltage rating remains at 300V with improved current capacity (15A vs. 12A at UL), making it suitable for equivalent or less demanding applications.

Mechanical Compatibility: Identical pitch (5.08mm), wire entry orientation (270°), mounting configuration (free-hanging in-line), and wire gauge range (12-30 AWG) ensure direct mechanical interchangeability.

Termination Enhancement: The 1829604 incorporates screw-clamping yoke (tension sleeve) termination with retention latches, providing improved wire retention compared to standard screw termination.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1829604 directly replace the 5439840 in existing installations?

A: Yes. Both components share identical mechanical specifications (9 positions, 5.08mm pitch, 270° wire entry, free-hanging mounting) and compatible electrical ratings within UL standards. The 1829604 is mechanically and electrically interchangeable.

Q: What is the difference in termination between these two parts?

A: The 5439840 uses standard screw termination. The 1829604 uses screw-clamping yoke (tension sleeve) termination with retention latches, providing enhanced wire retention and reduced risk of wire displacement.

Q: Are there voltage rating differences I should consider?

A: The IEC voltage rating differs (630V vs. 250V), but both maintain 300V UL rating. For applications operating within 300V UL specifications, the 1829604 is fully compatible. Applications requiring 630V IEC rating should verify system voltage requirements before substitution.

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

A: Yes. Both the 5439840 and 1829604 accommodate 12-30 AWG (0.2-2.5mm²) wire sizes without modification.

Q: Is the 1829604 available in the same packaging as the 5439840?

A: The 1829604 is supplied in bulk packaging, whereas the 5439840 packaging specification is not defined. Verify packaging requirements for your procurement process.

Q: Are both parts RoHS compliant?

A: Yes. Both the 5439840 and 1829604 are RoHS compliant with MSL rating of 1 (unlimited moisture sensitivity level).
