Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the Phoenix Contact 5439455 is determined by the following critical parameters:

• Electrical Compatibility: Current rating (8A IEC/UL), voltage rating (320V IEC / 300V UL), and wire gauge support (14-30 AWG / 0.2-1.5mm²)
• Mechanical Compatibility: 12-position configuration, 0.150" (3.81mm) pitch, 270° wire entry orientation, and free-hanging in-line mounting
• Interface Compatibility: Female socket type, screw termination method, M2 screw size, and matching insulation height (0.752" / 19.10mm)
• Material & Certification: Polyamide housing, tin contact finish, UL94 V-0 flammability rating, and RoHS compliance

The substitute part Phoenix Contact 1827075 meets all critical electrical and mechanical parameters while offering active product status and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1827075 is a direct functional substitute for the obsolete 5439455. Both parts maintain identical electrical ratings (8A / 320V IEC), mechanical configuration (12-position, 3.81mm pitch, 270° entry), and core material specifications (polyamide housing, tin finish, UL94 V-0).

Key differentiators supporting the 1827075 selection:

• Product Status: The 1827075 carries active product status, ensuring long-term availability and continued manufacturer support, whereas the 5439455 is obsolete.
• Compliance Enhancement: The 1827075 meets ROHS3 Compliant and REACH Unaffected certifications, providing superior regulatory alignment compared to the base RoHS Compliant status of the 5439455.
• Termination Advancement: The 1827075 features rising cage clamp termination, a modern screw terminal design that improves wire retention reliability.
• Wire Gauge Flexibility: The 1827075 supports wire gauges down to 0.14mm² (versus 0.2mm² minimum for the 5439455), offering expanded compatibility with finer gauge conductors.
• Documented Torque Specification: The 1827075 provides explicit torque specification (0.22-0.25 Nm / 1.9-2.2 Lb-In) and wire strip length (7mm), enabling precise installation procedures.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1827075 directly replace 5439455 in existing installations?

A: Yes. Both parts share identical electrical ratings (8A / 320V IEC), 12-position configuration, 3.81mm pitch, 270° wire entry, and free-hanging mounting. Mechanical and electrical compatibility is confirmed across all critical parameters.

Q: What is the significance of the rising cage clamp termination in the 1827075?

A: Rising cage clamp is a screw terminal design that provides enhanced wire retention and contact pressure consistency compared to standard screw termination. This represents a design improvement in the substitute part.

Q: Does the wire gauge range difference (0.2-1.5mm² vs. 0.14-1.5mm²) affect substitution?

A: No. The 1827075 supports a broader minimum wire gauge range (0.14mm²), making it compatible with all wire sizes supported by the 5439455 (0.2-1.5mm²). This represents expanded capability without compatibility loss.

Q: Are there packaging differences between these parts?

A: The 5439455 packaging is unspecified in available documentation. The 1827075 is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: What compliance advantage does ROHS3 provide over RoHS Compliant?

A: ROHS3 represents the current iteration of the Restriction of Hazardous Substances directive with updated substance restrictions. The 1827075 meets this current standard, whereas the 5439455 meets the base RoHS Compliant specification. For new designs and long-term compliance, ROHS3 is the preferred standard.

Q: Is torque specification critical for installation?

A: The 1827075 provides explicit torque specification (0.22-0.25 Nm). While the 5439455 does not document torque values, M2 screw sizing is identical. Use the documented 1827075 torque specification for installation to ensure proper contact pressure and reliability.
