Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5439374 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Current rating (8A IEC/UL), voltage rating (320V IEC / 300V UL), and wire gauge range (14-30 AWG / 0.2-1.5mm²)
• Mechanical Compatibility: 4-position configuration, 0.150" (3.81mm) pitch, 270° wire entry orientation, free-hanging in-line mounting
• Termination Interface: Screw-based termination with M2 screw size
• Physical Dimensions: Insulation height of 0.752" (19.10mm)
• Material & Safety: Polyamide housing, UL94 V-0 flammability rating, tin contact mating finish

The Phoenix Contact 1826995 qualifies as a direct substitute based on full alignment with these parameters. While the 1826995 features an upgraded termination mechanism (Rising Cage Clamp) and active product status, it maintains electrical and mechanical compatibility with the 5439374 across all critical substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1826995 is the qualified substitute for the obsolete 5439374 based on the following engineering criteria:

Electrical Equivalence: Both parts maintain identical current (8A) and voltage (320V IEC / 300V UL) ratings, ensuring direct functional replacement in existing circuits without derating or circuit modification.

Mechanical Compatibility: Identical 4-position, 3.81mm pitch configuration with 270° wire entry and free-hanging in-line mounting ensures direct mechanical fit in existing connector housings and cable assemblies.

Termination Compatibility: Both parts utilize M2 screw termination. The 1826995 incorporates a Rising Cage Clamp mechanism, which is a design enhancement that maintains screw-based termination compatibility while improving wire retention characteristics.

Compliance Status: The 1826995 carries active product status with ROHS3 compliance, providing superior long-term availability and regulatory alignment compared to the obsolete 5439374. Both parts maintain UL94 V-0 flammability certification and tin contact mating finish.

Wire Gauge Compatibility: The 1826995 supports the full 14-30 AWG range of the 5439374, with extended lower-gauge capability (0.14mm² vs. 0.2mm²), ensuring compatibility with all wire sizes specified for the original part.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1826995 directly replace the 5439374 in existing assemblies?

A: Yes. The 1826995 maintains electrical equivalence (8A, 320V IEC), identical mechanical configuration (4-position, 3.81mm pitch, 270° entry), and compatible M2 screw termination. Direct substitution is supported without circuit or mechanical redesign.

Q: What is the difference between the screw termination styles?

A: The 5439374 uses standard screw termination. The 1826995 uses Screw - Rising Cage Clamp termination, which provides enhanced wire retention and strain relief while maintaining the same M2 screw interface and torque specifications (0.22-0.25 Nm).

Q: Are there wire gauge compatibility concerns?

A: No. Both parts accept 14-30 AWG wire. The 1826995 extends compatibility to 0.14mm² (versus 0.2mm² minimum for the 5439374), providing broader gauge support while maintaining full compatibility with the original specification range.

Q: Why is the 5439374 listed as obsolete?

A: The 5439374 belongs to the legacy BCVP series. Phoenix Contact has transitioned to the active COMBICON MCVW series, represented by the 1826995, which incorporates design improvements while maintaining backward compatibility.

Q: What packaging differences exist between these parts?

A: The 5439374 packaging is unspecified in available documentation. The 1826995 is supplied in bulk packaging, which is standard for active production components. Packaging does not affect electrical or mechanical compatibility.

Q: Are both parts RoHS compliant?

A: Yes. The 5439374 is RoHS Compliant. The 1826995 is ROHS3 Compliant, representing compliance with the current regulatory standard. Both parts meet RoHS requirements for hazardous substance restrictions.

Q: What is the wire strip length specification?

A: The 5439374 wire strip length is not specified. The 1826995 specifies 7mm wire strip length, which is standard for this connector class and does not affect substitution compatibility.
