Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5449759 is determined by strict alignment of the following critical parameters:

• 10-position configuration with 0.150" (3.81mm) pitch spacing
• Female socket plug type with 90° wire entry orientation
• Free-hanging in-line mounting configuration
• Minimum current rating of 8A (IEC) and voltage rating of 320V (IEC)
• Wire gauge compatibility within 14-30 AWG range
• Screw-based termination mechanism
• UL94 V-0 flammability rating
• Polyamide (PA) nylon housing material

The substitute part Phoenix Contact 1828427 meets all critical substitution criteria. Both components share identical position count, pitch, connector type, mounting style, and electrical ratings. The substitute employs a rising cage clamp termination variant, which is functionally compatible with the original screw termination design while offering enhanced wire retention characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1828427 is the direct substitute for the obsolete 5449759. Both components are manufactured by Phoenix Contact and maintain identical electrical specifications, mechanical dimensions, and safety certifications. The 1828427 is currently in active production status with higher inventory availability (1114 pcs vs. 708 pcs), ensuring supply chain continuity.

The substitute part carries ROHS3 compliance, representing current regulatory alignment, while the original part meets RoHS compliance. Both components achieve UL94 V-0 flammability rating and share identical ECCN and HTSUS classifications. The rising cage clamp termination in the 1828427 provides equivalent functionality to the original screw termination, with documented torque specifications (0.22-0.25 Nm) and standardized wire strip length (7mm).

For applications currently using the 5449759, direct substitution with the 1828427 is supported by matching electrical ratings, mechanical compatibility, and regulatory compliance across both IEC and UL standards.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1828427 directly replace the 5449759 in existing installations?

A: Yes. Both components share identical position count (10), pitch spacing (0.150"/3.81mm), electrical ratings (8A/320V IEC, 8A/300V UL), wire gauge compatibility (14-30 AWG), and mechanical mounting configuration (free-hanging in-line). The rising cage clamp termination in the 1828427 is functionally equivalent to the screw termination in the 5449759.

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

A: Both termination methods secure wire connections using M2 fasteners. The rising cage clamp variant in the 1828427 incorporates a spring-loaded mechanism that automatically adjusts wire positioning during insertion, while the original screw termination requires manual adjustment. Both achieve equivalent electrical and mechanical performance within the specified current and voltage ratings.

Q: Are there any wire gauge compatibility differences between these parts?

A: The 5449759 accepts 0.2-1.5mm² wire, while the 1828427 accepts 0.14-1.5mm². The 1828427 supports a slightly lower minimum wire gauge. Both parts accommodate the full 14-30 AWG range, ensuring compatibility with standard industrial wiring practices.

Q: What packaging differences exist between these components?

A: The 5449759 was supplied with unspecified packaging, while the 1828427 is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact component functionality or electrical performance.

Q: Do both parts meet current regulatory compliance standards?

A: The 1828427 carries ROHS3 compliance and REACH unaffected status, representing current regulatory alignment. The 5449759 meets RoHS compliance. Both components achieve UL94 V-0 flammability rating and share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications, confirming regulatory equivalence for industrial applications.
