Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 3003732 is determined by the following critical parameters:

Connector Type: Feed-through terminal block with 2 positions and 1 level
Termination Method: Push-in spring mechanism
Terminal Geometry: 5.2 mm terminal width
Electrical Performance: Current and voltage ratings must meet or exceed IEC and UL specifications
Wire Gauge Compatibility: Acceptable wire gauge range must encompass or extend the 14-26 AWG (0.14-2.5 mm²) specification
Material & Compliance: Polyamide insulation with UL94 V-0 flammability rating and RoHS compliance

The substitute part Phoenix Contact 3244119 meets these criteria through equivalent feed-through architecture, identical 2-position configuration, matching 5.2 mm terminal width, and compatible push-in spring termination. The substitute provides enhanced current capacity (24 A IEC / 20 A UL) and extended wire gauge range (12-28 AWG / 0.08-4 mm²), maintaining full electrical and mechanical compatibility while offering improved performance margins.

Engineering Selection Recommendations

The Phoenix Contact 3244119 serves as a direct functional substitute for the obsolete 3003732. Both components maintain identical mechanical interfaces (2-position, 5.2 mm terminal width, push-in spring termination) and equivalent electrical safety standards (UL94 V-0 flammability, 800V IEC / 600V UL voltage ratings).

The 3244119 provides superior performance characteristics with increased current capacity (24 A IEC vs. 17.5 A IEC; 20 A UL vs. 15 A UL) and expanded wire gauge accommodation (12-28 AWG vs. 14-26 AWG). These enhancements ensure compatibility with a broader range of conductor sizes while maintaining safety margins in existing applications.

Compliance status differs: the 3003732 carries RoHS Compliant certification, while the 3244119 meets ROHS3 Compliant standards, reflecting updated regulatory requirements. Both components are classified as polyamide nylon insulation with identical flammability ratings.

The 3244119 is designated Last Time Buy status, indicating limited future availability. For applications requiring the 3003732, transition to the 3244119 is supported by mechanical and electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 3244119 directly replace the 3003732 in existing designs?

A: Yes. Both components share identical feed-through architecture, 2-position configuration, 5.2 mm terminal width, and push-in spring termination. Mechanical mounting and electrical interface compatibility are maintained.

Q: What are the key differences between these parts?

A: The 3244119 provides higher current ratings (24 A IEC / 20 A UL vs. 17.5 A IEC / 15 A UL) and extended wire gauge range (12-28 AWG vs. 14-26 AWG). Both maintain identical voltage ratings (800V IEC / 600V UL) and insulation material specifications.

Q: Are there wire gauge compatibility concerns?

A: No. The 3244119 wire gauge range (12-28 AWG / 0.08-4 mm²) fully encompasses the 3003732 specification (14-26 AWG / 0.14-2.5 mm²). Applications using the original part fall within the substitute's rated range.

Q: How do the RoHS certifications differ?

A: The 3003732 carries RoHS Compliant status, while the 3244119 meets ROHS3 Compliant standards. ROHS3 represents updated regulatory compliance. Both components satisfy RoHS requirements for their respective certification levels.

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

A: The 3003732 is obsolete, indicating discontinued production. The 3244119 is Last Time Buy status, meaning limited inventory remains available. For new designs or long-term applications, the 3244119 should be selected before availability expires.

Q: Are voltage and current ratings sufficient for my application?

A: The 3244119 exceeds the 3003732 ratings in current capacity while maintaining identical voltage specifications. Applications operating within the original part's electrical limits will operate safely with the substitute.
