Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5439552 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 3
• Pitch: 0.197" (5.00mm)
• Type: Plug, Female Sockets
• Plug Wire Entry: 270°
• Mounting Type: Free Hanging (In-Line)
• Wire Gauge Range: 12-30 AWG / 0.2-2.5mm²

Electrical Compatibility Parameters:

• Current Rating: Minimum 12A (IEC standard)
• Voltage Rating: Minimum 300V (UL standard) or 630V (IEC standard)
• Contact Mating Finish: Tin

Compliance Parameters:

• RoHS Compliance: Required
• Material Flammability: UL94 V-0 or equivalent

The substitute part Phoenix Contact 1839908 meets all mandatory matching parameters and electrical compatibility requirements, with the exception of IEC voltage rating (250V vs. 630V). The 1839908 features an enhanced termination method (Screw - Clamping Yoke with Tension Sleeve) and includes retention latches for improved mechanical stability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Phoenix Contact 1839908

The 1839908 is the designated equivalent for the obsolete 5439552. Both components are manufactured by Phoenix Contact and maintain identical mechanical and electrical specifications across all critical parameters: 3-position configuration, 5.00mm pitch, 270° wire entry, and free-hanging in-line mounting.

Compliance Status: Both parts are RoHS compliant and carry EAR99 ECCN classification. The 1839908 is currently in active production status, ensuring long-term availability and supply chain continuity.

Electrical Considerations: The 1839908 provides UL voltage rating of 300V, matching the original part's UL specification. The IEC voltage rating differs (250V vs. 630V); applications requiring 630V IEC compliance must evaluate system voltage requirements against the substitute's 250V IEC rating.

The 1839908 offers enhanced current capacity under UL standards (15A vs. 12A), providing additional margin for applications operating at the original part's 12A specification.

Termination Enhancement: The 1839908 employs a Screw - Clamping Yoke (Tension Sleeve) termination method with retention latches, providing improved mechanical stability and wire retention compared to the standard screw termination of the 5439552.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1839908 directly replace the 5439552 in all applications?

A: The 1839908 is mechanically and electrically compatible for applications operating within its electrical ratings. The primary consideration is IEC voltage compliance: the 1839908 is rated 250V IEC versus the 5439552's 630V IEC. Applications requiring 630V IEC certification must evaluate whether 250V IEC operation is acceptable for the specific system design.

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

A: The 5439552 uses standard screw termination. The 1839908 uses Screw - Clamping Yoke (Tension Sleeve) termination with retention latches. The clamping yoke design provides enhanced wire retention and reduced connection resistance, representing a technical improvement over the original design.

Q: Are both parts RoHS compliant?

A: Yes, both the 5439552 and 1839908 are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.

Q: What is the current availability status of these parts?

A: The 5439552 is obsolete but currently has 933 pieces in stock. The 1839908 is in active production status with 769 pieces in stock, ensuring continued availability for new designs and replacements.

Q: Are the wire gauge specifications identical?

A: Yes, both parts support 12-30 AWG wire gauge range (0.2-2.5mm²), ensuring compatibility with existing wiring infrastructure.

Q: Does the 1839908 offer any performance advantages?

A: The 1839908 provides higher UL current rating (15A vs. 12A) and improved mechanical retention through clamping yoke design with latches. These enhancements represent design improvements while maintaining backward compatibility with the original 5439552 specifications.
