Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1939581 is determined by strict equivalence across the following critical parameters:

• 8-position configuration with 7.5mm pitch spacing
• Female socket plug type with 180° wire entry orientation
• Screwless push-in spring termination mechanism
• Free-hanging in-line mounting configuration
• Electrical ratings: 12A (IEC), 1 kV (IEC), 10A (UL), 300V (UL)
• Wire gauge compatibility: 12-26 AWG (0.2-2.5mm²)
• Housing material: Polyamide (PA), Nylon with UL94 V-0 flammability rating
• RoHS compliance and MSL 1 moisture sensitivity level

The Phoenix Contact 1939471 meets all these criteria and is classified as an active product, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1939471 is the direct substitute for the obsolete 1939581. Both components are manufactured by Phoenix Contact within the COMBICON GFKC series and maintain identical electrical, mechanical, and environmental specifications. The 1939471 holds active product status with 1118 units in stock, compared to the 1939581's obsolete classification with 706 units available.

Selection of the 1939471 is supported by:

• Identical electrical performance across IEC and UL rating systems
• Matching mechanical dimensions and termination methodology
• Equivalent material composition and flammability certification (UL94 V-0)
• Full RoHS compliance and MSL 1 moisture sensitivity rating
• Consistent export classification (EAR99) and tariff coding

The primary distinction is packaging format: the 1939471 is supplied in bulk packaging, whereas the 1939581 packaging specification is not provided. This difference does not affect functional compatibility or electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the 1939471 directly replace the 1939581 in existing applications?

A: Yes. Both components are identical in electrical ratings (12A IEC, 1 kV IEC, 10A UL, 300V UL), mechanical configuration (8-position, 7.5mm pitch, 180° wire entry), and termination method (screwless push-in spring). They are mechanically and electrically interchangeable.

Q: What is the significance of the 1939581 being classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 1939471 remains in active production, ensuring long-term availability and supply chain continuity for new designs and maintenance applications.

Q: Are there any differences in wire gauge compatibility?

A: No. Both the 1939581 and 1939471 accept wire gauges from 12-26 AWG (0.2-2.5mm²) with identical 10mm wire strip length specifications.

Q: Does packaging format affect electrical or mechanical performance?

A: No. The 1939471 bulk packaging does not alter component specifications, performance characteristics, or compatibility. Packaging is a logistics consideration only.

Q: Are both components RoHS compliant?

A: Yes. Both the 1939581 and 1939471 are RoHS compliant with MSL 1 (unlimited) moisture sensitivity ratings, suitable for standard storage and handling conditions.

Q: What is the contact mating finish for both components?

A: Both components feature tin contact mating finish, providing consistent electrical contact resistance and corrosion resistance across equivalent applications.
