Phoenix Contact 5452757 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5452757 is an 8-position terminal block plug with female sockets, 0.200" (5.08mm) pitch, designed for 90° free-hanging in-line applications. This component operates at 12A (IEC) / 12A (UL) and 320V (IEC) / 300V (UL), accommodating wire gauges from 12-30 AWG (0.2-2.5mm²). The part belongs to the BCVP series and carries an obsolete product status. Due to its obsolescence, identifying functionally equivalent active alternatives is essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5452757 is determined by strict alignment across the following critical parameters:

• Connector Configuration: 8 positions, 0.200" (5.08mm) pitch, female socket plug type
• Electrical Performance: 12A current rating (IEC), 250V minimum voltage rating (IEC), compatible with 12-30 AWG wire gauges
• Mechanical Interface: 90° wire entry, free-hanging in-line mounting, M3 screw termination with 0.5-0.6 Nm torque specification
• Physical Dimensions: 1.024" (26.01mm) insulation height, 7mm wire strip length
• Compliance: RoHS compliant, MSL 1 rating

The substitute part Phoenix Contact 1777701 meets all these criteria. While it features a rising cage clamp termination variant and operates at 250V (IEC) rather than 320V (IEC), these differences represent functional equivalence within the allowed parameter range for this product category. The 250V rating remains suitable for applications rated at or below this voltage threshold.

Engineering Selection Recommendations

The Phoenix Contact 1777701 is the designated substitute for the obsolete 5452757. Selection is based on the following engineering criteria:

Product Status: The 5452757 carries obsolete status, making the active 1777701 the appropriate choice for system continuity and future procurement.

Compliance Alignment: Both parts maintain RoHS compliance and MSL 1 ratings, ensuring compatibility with modern manufacturing and storage requirements.

Electrical Compatibility: The 1777701 operates at 250V (IEC), which is lower than the 5452757's 320V rating. This difference is acceptable for applications designed to operate at or below 250V. For applications requiring the full 320V rating, the 1777701 is not suitable.

Mechanical Compatibility: Identical pitch (5.08mm), position count (8), wire entry angle (90°), mounting configuration (free-hanging in-line), and screw specifications (M3, 0.5-0.6 Nm) ensure direct mechanical interchangeability.

Termination Variant: The 1777701 employs a rising cage clamp termination mechanism rather than standard screw termination. This represents a functional enhancement in wire retention and does not compromise compatibility with existing connector housings or mating interfaces.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1777701 directly replace the 5452757 in all applications?

A: Direct replacement is possible only in applications operating at 250V (IEC) or below. The 5452757 supports 320V (IEC), while the 1777701 is rated for 250V (IEC). Verify your system voltage requirements before substitution.

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

A: Both termination methods secure wires using M3 screws with identical torque specifications (0.5-0.6 Nm). The rising cage clamp variant in the 1777701 provides enhanced wire retention through a mechanical cage mechanism that rises as the screw tightens, offering improved contact pressure consistency.

Q: Are the physical dimensions identical between the two parts?

A: Yes. Both parts share identical pitch (5.08mm), insulation height (1.024"), wire strip length (7mm), and overall form factor, ensuring mechanical interchangeability in connector housings and mounting applications.

Q: What is the significance of the different series designations (BCVP vs. COMBICON MVSTBR)?

A: Series designations reflect product line evolution within Phoenix Contact's terminal block portfolio. The BCVP series (5452757) is obsolete, while COMBICON MVSTBR (1777701) represents the current active product line. The designation change does not affect electrical or mechanical compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the 5452757 and 1777701 are RoHS compliant with MSL 1 ratings, meeting current environmental and moisture sensitivity requirements.

Q: What wire gauges are supported by the 1777701?

A: The 1777701 accommodates 12-30 AWG wire gauges (0.2-2.5mm²), identical to the 5452757, ensuring compatibility with existing wiring specifications.
