Engineering Selection Recommendations

The Phoenix Contact 1939413 is the direct functional equivalent to the obsolete 1939523. Both components are manufactured by Phoenix Contact within the COMBICON GFKC series and maintain identical electrical, mechanical, and material specifications.

Product Status Consideration: The 1939523 is classified as obsolete, while the 1939413 maintains active product status. This distinction is significant for long-term supply chain planning and component availability.

Compliance Status: Both parts meet RoHS requirements. The 1939413 carries ROHS3 compliance designation, representing current regulatory alignment. The 1939523 is RoHS compliant. Both components are rated UL94 V-0 for material flammability and carry MSL 1 (Unlimited) moisture sensitivity classification.

Regulatory Certifications: Both parts are classified under ECCN EAR99 and HTSUS 8536.90.4000, indicating equivalent export and tariff treatment.

Feature Differentiation: The 1939523 includes mating flange and retention latches (non-wire side) features. The 1939413 specifies retention latches (non-wire side) only. This represents a minor design refinement rather than a functional limitation.

For new designs and procurement requiring active component status, the 1939413 is the appropriate selection. For legacy system maintenance where the 1939523 is currently deployed, the 1939413 provides direct functional replacement.

Frequently Asked Questions (FAQ)

Q: Can the 1939413 directly replace the 1939523 in existing applications?

A: Yes. Both components share identical electrical ratings (12A IEC / 10A UL, 1 kV IEC / 300V UL), mechanical configuration (2-position, 7.5mm pitch, 180° wire entry), termination method (screwless push-in spring), and material specifications (polyamide housing, tin contact finish, UL94 V-0 flammability rating). The 1939413 is functionally equivalent for all specified parameters.

Q: What is the significance of the product status difference?

A: The 1939523 is obsolete, indicating Phoenix Contact no longer manufactures or supports this part number. The 1939413 maintains active status, ensuring ongoing availability, technical support, and compliance with current regulatory standards. For new procurement, the 1939413 is the recommended selection.

Q: Are there packaging differences between these parts?

A: The 1939523 is listed with unspecified packaging, while the 1939413 is supplied in bulk packaging. Packaging configuration does not affect electrical or mechanical compatibility.

Q: Do both parts meet current RoHS requirements?

A: Yes. The 1939523 is RoHS compliant. The 1939413 carries ROHS3 compliance, representing alignment with the current regulatory framework. Both parts satisfy RoHS requirements for new applications.

Q: What wire gauges are supported by these terminal blocks?

A: Both the 1939523 and 1939413 accept wire gauges from 12-26 AWG, equivalent to 0.2-2.5mm². Wire strip length is 10mm for both components.

Q: Are there any feature differences that affect functionality?

A: The 1939523 includes both mating flange and retention latches (non-wire side). The 1939413 specifies retention latches (non-wire side). This represents a design refinement. Both configurations maintain the same electrical and mechanical performance for the specified application parameters.

Q: What is the moisture sensitivity level for these components?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage, handling, or use.
