Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELFH14280 are qualified based on the following criteria:

Electrical Compatibility: Voltage and current ratings must meet or exceed the original specification. The ELFH14280 operates at 300V UL and 15A UL. Substitute parts must support these electrical parameters.

Mechanical Compatibility: Number of positions (14), pitch spacing (5.08mm nominal), and vertical through-hole mounting orientation must be maintained. Minor pitch variations (5.00mm vs 5.08mm) are acceptable within standard PCB layout tolerances for terminal block applications.

Shrouding Configuration: The ELFH14280 features 4-side shrouding. Substitutes with equivalent or greater shrouding (4-side) are directly interchangeable. Parts with reduced shrouding (2-side) may be used in applications where the reduced shrouding does not compromise electrical isolation requirements.

Termination and Contact: Solder termination and tin contact mating finish are standard across all qualified substitutes.

Compliance: RoHS compliance and UL94 V-0 flammability rating are required for all substitutes.

Parameter Comparison

Engineering Selection Recommendations

1755626 (Phoenix Contact COMBICON MSTBVA): This part is the primary substitute for the ELFH14280. It maintains identical 4-side shrouding configuration, vertical through-hole mounting, and 14-position layout. The pitch difference (5.00mm vs 5.08mm) is within standard PCB layout tolerances. The UL current rating is 12A compared to 15A on the original part; applications requiring the full 15A rating must verify that 12A is sufficient. Both parts meet UL 300V voltage requirements and UL94 V-0 flammability standards. ROHS3 compliance exceeds the RoHS requirement. This part is active in production with 688 units in stock.

1753673 (Phoenix Contact COMBICON MSTBV): This part is a secondary substitute suitable for applications where 2-side shrouding is acceptable. It shares the same 14-position count, vertical orientation, and through-hole mounting as the ELFH14280. The pitch (5.00mm) and electrical ratings (12A UL, 300V UL) are equivalent to part 1755626. The reduced shrouding (2-side vs 4-side) may impact electrical isolation in high-density or high-noise environments. This part is active in production with 1081 units in stock, offering the highest inventory availability.

Compliance Considerations: All three parts are active products with current manufacturing status. The ELFH14280 is RoHS Compliant; both Phoenix Contact substitutes are ROHS3 Compliant, which represents an enhanced compliance standard. All parts carry UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating, indicating no special storage requirements.

Frequently Asked Questions (FAQ)

Q: Can I use part 1755626 as a direct replacement for ELFH14280 in my PCB design?

A: Part 1755626 is mechanically and electrically compatible for most applications. The pitch difference (5.00mm vs 5.08mm) is approximately 0.08mm per position and falls within standard PCB layout tolerances. However, verify that your PCB footprint can accommodate this minor variation. The 4-side shrouding matches the original design. The UL current rating is 12A versus 15A; confirm that your application does not require the full 15A capacity.

Q: What is the difference between 1755626 and 1753673?

A: Both parts are Phoenix Contact COMBICON series with identical electrical ratings (12A UL, 300V UL) and pitch (5.00mm). The primary difference is shrouding: 1755626 has 4-side shrouding (matching ELFH14280), while 1753673 has 2-side shrouding. Select 1755626 for direct mechanical compatibility. Select 1753673 only if 2-side shrouding is acceptable for your application.

Q: Does the pitch difference (5.08mm vs 5.00mm) affect PCB compatibility?

A: The pitch difference is 0.08mm per position, or approximately 1.12mm across all 14 positions. This is within standard PCB manufacturing tolerances for terminal block footprints. However, verify your specific PCB design and manufacturing capabilities. If your PCB is already manufactured with 5.08mm spacing, the 5.00mm parts may not fit without modification.

Q: Are all three parts RoHS compliant?

A: Yes. The ELFH14280 is RoHS Compliant. Parts 1755626 and 1753673 are ROHS3 Compliant, which represents an enhanced compliance standard that exceeds the base RoHS requirement. All three parts are suitable for RoHS-regulated applications.

Q: What is the current rating difference, and does it matter?

A: The ELFH14280 is rated for 15A (UL), while both Phoenix Contact substitutes are rated for 12A (UL). If your application draws 12A or less, both substitutes are suitable. If your application requires 13–15A, the ELFH14280 is the only option among these three parts. Verify your actual current draw before selecting a substitute.

Q: Can I mix ELFH14280 and 1755626 in the same assembly?

A: Both parts are mechanically and electrically compatible and can be used in the same assembly if PCB footprints are designed to accommodate the pitch variation. However, for consistency and to avoid assembly confusion, it is preferable to standardize on a single part number per design.

Q: What is the inventory status for each part?

A: ELFH14280 has 866 units in stock. Part 1755626 has 688 units. Part 1753673 has 1081 units, offering the highest availability. Inventory levels may change; verify current stock with your supplier.
