Phoenix Contact 5439950 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5439950 is a 20-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 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. The obsolete status necessitates evaluation of active alternative models that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the Phoenix Contact 5439950 is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: 20 positions at 0.200" (5.08mm) spacing
• Connector Type & Gender: Plug with female sockets
• Wire Entry Orientation: 270° free-hanging in-line configuration
• Electrical Ratings: IEC 12A at 630V minimum
• Termination Interface: Screw-based wire connection
• Wire Gauge Compatibility: 12-30 AWG (0.2-2.5mm²)
• Mechanical Mounting: Free-hanging in-line mounting
• Material & Safety Compliance: Polyamide housing, UL94 V-0 flammability rating

The substitute part Phoenix Contact 1792935 maintains all critical parameters within acceptable engineering tolerances. Variations in termination mechanism (rising cage clamp vs. standard screw), housing color, and product status do not affect functional interchangeability when electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1792935 is a direct functional equivalent to the obsolete 5439950 model. Selection of the substitute part is supported by the following engineering criteria:

Electrical Compatibility: Both parts maintain identical IEC electrical ratings (12A at 630V) and UL ratings (300V). The substitute's higher UL current rating (15A vs. 12A) provides additional margin without introducing incompatibility.

Mechanical Compatibility: Pitch, position count, wire entry angle, mounting configuration, and screw specifications are identical. The rising cage clamp termination mechanism in the substitute represents an enhancement to the standard screw termination while maintaining the same M3 screw interface and torque specification.

Compliance Status: The substitute part carries active ROHS3 compliance, exceeding the RoHS compliance of the obsolete part. Both maintain UL94 V-0 flammability certification, ensuring equivalent safety performance in applications requiring flame-retardant materials.

Availability: The substitute part (1792935) is in active production with 1311 units in stock, compared to the obsolete status of the original part with limited remaining inventory (751 units).

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1792935 directly replace the 5439950 in existing installations?

A: Yes. Both parts share identical position count (20), pitch (5.08mm), wire entry orientation (270°), mounting type (free-hanging in-line), and electrical ratings (IEC 12A at 630V). The M3 screw interface and torque specification (0.5-0.6 Nm) are identical, enabling direct mechanical and electrical substitution.

Q: What is the difference between the screw termination and rising cage clamp termination?

A: The 5439950 uses standard screw termination. The 1792935 uses screw-based rising cage clamp termination, which provides enhanced wire retention through a mechanical locking mechanism. Both accept identical wire gauge ranges (12-30 AWG) and use the same M3 screw size with matching torque specifications.

Q: Are there any compliance differences between the two parts?

A: The 5439950 is RoHS Compliant. The 1792935 is ROHS3 Compliant, representing a more current regulatory standard. Both maintain UL94 V-0 flammability certification. The substitute part meets or exceeds all compliance requirements of the original part.

Q: Does the substitute part support the same wire gauge range?

A: Yes. Both parts accommodate 12-30 AWG wire (0.2-2.5mm²) with identical screw torque specifications (0.5-0.6 Nm).

Q: What is the packaging difference between these parts?

A: The 5439950 is supplied in standard packaging. The 1792935 is supplied in bulk packaging. This difference does not affect electrical or mechanical performance.

Q: Why is the original part obsolete?

A: The 5439950 is classified as obsolete by Phoenix Contact. The 1792935 represents the active production equivalent within the COMBICON MVSTBW series, offering enhanced features (retention latches) while maintaining full backward compatibility with the original specification.
