Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1939549 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Current rating (12A IEC / 10A UL), voltage rating (1 kV IEC / 300V UL), and wire gauge acceptance (12-26 AWG / 0.2-2.5mm²) must match exactly
• Mechanical Compatibility: 4-position configuration, 7.5mm pitch, 180° wire entry orientation, and free-hanging in-line mounting must be identical
• Termination Method: Screwless push-in spring termination is required
• Material & Compliance: Polyamide housing with UL94 V-0 flammability rating and RoHS compliance must be maintained

The Phoenix Contact 1939439 meets all substitution criteria as an active product within the same COMBICON GFKC series, offering direct functional and electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1939439 is the direct equivalent substitute for the obsolete 1939549. Both components are manufactured by Phoenix Contact within the COMBICON GFKC series and maintain identical electrical, mechanical, and material specifications across all critical parameters.

The 1939439 is classified as an active product with higher inventory availability (1050 pcs vs. 652 pcs), ensuring reliable procurement for new designs and replacement applications. Both parts carry RoHS compliance and UL94 V-0 flammability certification, meeting current regulatory requirements.

The only documented difference is packaging format (bulk for 1939439 vs. unspecified for 1939549) and the absence of a mating flange feature on the 1939439. This feature difference does not affect electrical or mechanical compatibility in standard terminal block applications.

Frequently Asked Questions (FAQ)

Q: Can the 1939439 directly replace the 1939549 in existing applications?

A: Yes. Both components share identical electrical ratings (12A at 1 kV IEC), mechanical configuration (4-position, 7.5mm pitch, 180° wire entry), termination method (screwless push-in spring), and material specifications (polyamide housing, UL94 V-0). Direct substitution is supported without circuit or mechanical redesign.

Q: What is the significance of the mating flange feature difference?

A: The 1939549 includes a mating flange with retention latches on the non-wire side, while the 1939439 includes retention latches only. This difference affects mechanical mounting interface but does not impact electrical performance or wire termination capability. Evaluate your specific mounting requirements to confirm compatibility.

Q: Are there any compliance or certification differences between these parts?

A: No. Both components are RoHS compliant, carry UL94 V-0 flammability ratings, and share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications. Regulatory and environmental compliance requirements are equivalent.

Q: What wire gauges are supported by the 1939439?

A: The 1939439 accepts wire gauges from 12-26 AWG (0.2-2.5mm²), identical to the 1939549. Termination is via screwless push-in spring mechanism with 10mm wire strip length.

Q: Is the 1939439 available in higher quantities?

A: Yes. The 1939439 is an active product with 1050 pcs in stock compared to 652 pcs for the obsolete 1939549. For ongoing procurement, the 1939439 offers superior supply chain reliability.
