Phoenix Contact 5439002 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 5439002 is a 5-position terminal block plug with female sockets, 0.200" (5.08mm) pitch, designed for 90° free-hanging in-line applications. This component features screw termination, rated for 12A at 630V (IEC) and 300V (UL), and accommodates wire gauges from 12-30 AWG (0.2-2.5mm²). The part is currently obsolete, making identification of compatible substitute components essential for ongoing system maintenance and new designs requiring equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 5439002 is determined by strict equivalence in the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 5 positions at 0.200" (5.08mm) pitch to ensure mechanical and electrical compatibility with mating connectors
• Plug Configuration: Female socket configuration with 90° wire entry orientation must be preserved
• Mounting Style: Free-hanging in-line mounting type is mandatory for form-factor compatibility
• Wire Gauge Compatibility: Acceptable wire range of 12-30 AWG (0.2-2.5mm²) ensures proper conductor accommodation
• Electrical Ratings: Current and voltage ratings must meet or exceed the original specification to maintain system safety margins
• Insulation Height: Physical dimension of 1.024" (26.01mm) ensures proper spacing and clearance in existing assemblies

The Phoenix Contact 1825241 qualifies as a substitute based on matching all critical mechanical parameters and meeting electrical requirements within acceptable operating ranges.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1825241 serves as a direct functional substitute for the obsolete 5439002. Both components are RoHS compliant and manufactured by Phoenix Contact, ensuring regulatory alignment and supply chain continuity.

The 1825241 maintains mechanical compatibility through identical position count, pitch, wire entry angle, and insulation height. Electrical performance is equivalent or superior: while the IEC voltage rating decreases from 630V to 250V, the UL voltage rating remains at 300V and the UL current rating increases from 12A to 15A. For applications operating within 250V IEC or 300V UL specifications, the 1825241 provides full functional equivalence.

The 1825241 incorporates an enhanced termination design (Screw - Clamping Yoke with Tension Sleeve) and includes retention latches on the wire side, offering improved mechanical stability compared to the original screw termination. These enhancements do not compromise compatibility but provide additional assembly robustness.

Selection of the 1825241 is appropriate for new designs and replacement applications where the component is currently in use, provided system voltage specifications do not exceed 250V (IEC) or 300V (UL).

Frequently Asked Questions (FAQ)

Q: Can the 1825241 directly replace the 5439002 in existing assemblies?

A: Yes, the 1825241 provides direct mechanical and electrical replacement. Both components share identical position count (5), pitch (0.200"/5.08mm), wire entry angle (90°), mounting configuration (free-hanging in-line), and insulation height (1.024"/26.01mm). Wire gauge compatibility is identical (12-30 AWG / 0.2-2.5mm²). Verify that your application voltage does not exceed 250V (IEC) or 300V (UL) specifications.

Q: What is the difference in termination style between these parts?

A: The 5439002 uses standard screw termination. The 1825241 employs screw termination with a clamping yoke (tension sleeve) mechanism and includes wire-side retention latches. This enhanced design provides improved conductor retention and assembly stability without affecting electrical or mechanical compatibility.

Q: Are there voltage rating differences I should consider?

A: The IEC voltage rating differs: 5439002 is rated 630V while 1825241 is rated 250V (IEC). Both are rated 300V (UL). For applications operating at IEC voltages above 250V, the 5439002 specification must be maintained. For standard industrial applications at 250V (IEC) or below, the 1825241 is fully suitable.

Q: Do both parts support the same wire gauge range?

A: Yes, both components accommodate 12-30 AWG (0.2-2.5mm²) wire gauges, ensuring identical conductor compatibility and assembly procedures.

Q: What is the product status difference, and why does it matter?

A: The 5439002 is obsolete, meaning Phoenix Contact no longer manufactures or supports this component. The 1825241 is active production, ensuring long-term availability, technical support, and supply chain reliability for current and future applications.
