Phoenix Contact 5439772 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5439772 is a 2-position terminal block plug with female sockets, 0.200" (5.08mm) pitch, and 270° free-hanging in-line configuration. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new designs requiring equivalent functionality.

The BCVP series plug accommodates wire gauges from 12-30 AWG (0.2-2.5mm²) with screw termination and supports IEC ratings of 12A at 630V. Given its obsolete status, sourcing alternatives that maintain electrical and mechanical compatibility is critical for system continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5439772 is determined by strict alignment with the following critical parameters:

• Connector Type & Configuration: 2-position plug with female sockets, 270° free-hanging in-line orientation
• Pitch Specification: 0.200" (5.08mm) center-to-center spacing
• Electrical Ratings: Minimum 12A current capacity and voltage compatibility
• Termination Method: Screw-based wire termination with M3 fastener
• Wire Accommodation: Support for 12-30 AWG (0.2-2.5mm²) wire gauges
• Mechanical Compatibility: Identical mounting type and physical form factor

The substitute part Phoenix Contact 1783889 meets all critical substitution criteria. It maintains identical position count, pitch, wire entry angle, mounting configuration, and wire gauge range. Both components use M3 screw termination with matching torque specifications and wire strip length. The substitute operates at 250V IEC (lower than the original 630V) but retains 12A current capacity, making it suitable for applications within its voltage envelope.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1783889 is the qualified substitute for the obsolete 5439772 based on the following engineering criteria:

Mechanical Compatibility: Both components share identical pitch (5.08mm), position count (2), wire entry orientation (270°), and mounting configuration (free hanging in-line). Physical interchangeability is confirmed.

Electrical Compatibility: The substitute maintains the 12A current rating and supports the same wire gauge range (12-30 AWG / 0.2-2.5mm²). The voltage rating difference (250V vs. 630V) requires application-level verification; the substitute is suitable for systems operating at or below 250V IEC.

Termination Compatibility: Both use M3 screw fasteners with identical torque specifications (0.5-0.6 Nm). The substitute incorporates rising cage clamp technology within the screw termination, which does not affect mechanical or electrical compatibility.

Compliance Status: Both components are RoHS compliant with MSL rating of 1 (unlimited moisture sensitivity). The substitute is active in production, ensuring long-term availability and supply chain stability compared to the obsolete original.

Series Transition: The substitute belongs to the COMBICON MVSTBW series, representing Phoenix Contact's current-generation equivalent to the legacy BCVP series.

Frequently Asked Questions (FAQ)

Q: Can the 1783889 directly replace the 5439772 in existing installations?

A: Direct mechanical and electrical replacement is possible for applications operating at 250V IEC or below. The identical pitch, position count, wire entry angle, and screw termination ensure physical interchangeability. Verify your system voltage rating before substitution.

Q: What is the significance of the voltage rating difference (630V vs. 250V)?

A: The original 5439772 is rated for 630V IEC, while the substitute 1783889 is rated for 250V IEC. The substitute is suitable only for systems with maximum operating voltages at or below 250V. Higher-voltage applications require alternative solutions.

Q: Are the wire gauge specifications identical between the two parts?

A: Yes. Both the 5439772 and 1783889 accommodate 12-30 AWG (0.2-2.5mm²) wire gauges with identical 7mm wire strip length and M3 screw termination torque (0.5-0.6 Nm).

Q: What does "rising cage clamp" termination mean in the substitute?

A: Rising cage clamp is an enhanced screw termination mechanism that improves wire retention and contact pressure consistency. It does not affect mechanical compatibility or electrical performance relative to standard screw termination.

Q: Is the substitute available in the same packaging as the original?

A: The original 5439772 packaging is not specified in available data. The substitute 1783889 is supplied in bulk packaging. Confirm packaging requirements for your procurement process.

Q: Are both components RoHS compliant?

A: Yes. Both the 5439772 and 1783889 are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity level).

Q: Why is the original part obsolete?

A: The 5439772 belongs to the legacy BCVP series. Phoenix Contact has transitioned to the COMBICON MVSTBW series (represented by the 1783889), which offers equivalent functionality with enhanced features and active production support.
