Phoenix Contact 5437761 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5437761 is a 3-position terminal block plug with female sockets, 0.150" (3.81mm) pitch, designed for 90° free-hanging in-line applications. This component operates at 8A (IEC/UL) and 320V (IEC) / 300V (UL), accommodating wire gauges from 14-30 AWG (0.2-1.5mm²). The part is currently obsolete, making identification of compatible substitutes essential for ongoing system maintenance and new designs requiring equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 5437761 is determined by strict equivalence in the following electrical and mechanical parameters:

• Electrical compatibility: Current rating (8A IEC/UL), voltage rating (320V IEC / 300V UL)
• Physical compatibility: 3-position configuration, 0.150" (3.81mm) pitch, 90° wire entry, free-hanging in-line mounting
• Termination interface: Screw-based connection system
• Material and safety: Polyamide housing, UL94 V-0 flammability rating
• Wire accommodation: Support for 14-30 AWG wire gauge range

The Phoenix Contact 1827130 meets all these criteria, with the primary distinction being its active product status and updated termination technology (rising cage clamp vs. standard screw).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1827130 is a direct functional equivalent to the 5437761 for applications requiring 3-position, 3.81mm pitch terminal block plugs with 8A/320V (IEC) electrical ratings and 90° free-hanging in-line mounting.

Primary advantages of the 1827130 substitute:

• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance provides enhanced regulatory alignment compared to RoHS compliance
• Rising cage clamp termination technology offers improved wire retention and connection reliability
• Expanded wire gauge accommodation (0.14-1.5mm²) provides greater flexibility for smaller gauge applications
• Identical electrical ratings, pitch, mounting configuration, and safety certifications ensure drop-in compatibility

Compliance considerations:

Both parts maintain UL94 V-0 flammability ratings, tin contact mating finish, M2 screw terminals, and MSL 1 moisture sensitivity levels. The 1827130 includes REACH unaffected status, providing additional environmental compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1827130 directly replace the 5437761 in existing applications?

A: Yes. Both parts share identical electrical ratings (8A/320V IEC), physical dimensions (3-position, 3.81mm pitch), mounting configuration (90° free-hanging in-line), and safety certifications (UL94 V-0). The primary difference is the termination mechanism (rising cage clamp vs. standard screw), which maintains functional compatibility.

Q: What is the significance of the rising cage clamp termination in the 1827130?

A: The rising cage clamp termination provides enhanced wire retention and connection security compared to standard screw terminals. This technology is part of Phoenix Contact's COMBICON MCVR series and represents an evolution in terminal block design while maintaining backward compatibility with the same electrical and mechanical specifications.

Q: Are there wire gauge differences between these parts?

A: The 1827130 accommodates wire gauges from 0.14-1.5mm², while the 5437761 specifies 0.2-1.5mm². The 1827130 supports smaller gauge wires (0.14-0.2mm²), providing greater application flexibility without compromising compatibility for standard 14-30 AWG applications.

Q: What is the difference between RoHS and ROHS3 compliance?

A: ROHS3 represents the current iteration of the Restriction of Hazardous Substances directive with updated substance restrictions and compliance requirements. Both ratings indicate compliance with hazardous substance limitations; ROHS3 reflects the most current regulatory standard.

Q: Is the 1827130 suitable for new designs?

A: Yes. The 1827130 is an active product with full availability. For new designs requiring 3-position, 3.81mm pitch terminal block plugs with 8A/320V ratings and 90° in-line mounting, the 1827130 is the recommended selection, offering current product support and enhanced termination technology.
