ELFH14290 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH14290 is a 14-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 5.08mm pitch spacing. This component features male pins with 2-side shrouding and is rated for 15A at 300V UL. The part is currently active in production with 763 units in stock. Equivalent and substitute parts are identified based on matching electrical ratings, mechanical dimensions, and mounting compatibility within the terminal block header category.

Substitute Part Grouping Explanation

Substitute parts for the ELFH14290 are identified based on the following critical parameters that determine functional compatibility:

Number of Positions: Must equal 14 positions
Pitch Spacing: Nominal 5.0mm to 5.08mm (mechanical tolerance allows minor variation)
Header Orientation: Vertical through-hole mounting
Connector Type: Male pins with shrouding
Voltage Rating: Minimum 300V UL
Current Rating: Minimum 12A (substitute parts rated at 12A UL are acceptable for applications within this amperage)
Termination Style: Solder
Flammability Rating: UL94 V-0
RoHS Compliance: RoHS or ROHS3 compliant

The identified substitutes are Phoenix Contact parts 1753673 and 1755626, both meeting these core electrical and mechanical criteria. The primary difference between substitutes is shrouding configuration (2-side vs. 4-side), which does not affect electrical performance but may impact mechanical fit in specific PCB layouts.

Engineering Selection Recommendations

Both Phoenix Contact substitutes (1753673 and 1755626) are suitable alternatives to the ELFH14290 based on electrical and mechanical compatibility. Selection between them depends on PCB layout requirements:

1753673 (2-Side Shrouded): Matches the shrouding configuration of the main part, providing identical mechanical envelope for direct replacement in existing designs. Recommended for applications where PCB layout has been optimized for 2-side shrouding.

1755626 (4-Side Shrouded): Provides enhanced mechanical protection with full shrouding on all sides. Suitable for applications requiring additional EMI shielding or mechanical robustness. Verify PCB footprint compatibility before selection, as the 4-side shrouding may require additional clearance.

Both substitutes are ROHS3 compliant and carry UL94 V-0 flammability ratings. The 0.08mm pitch difference (5.08mm vs. 5.00mm) falls within standard mechanical tolerances for terminal block headers and does not affect electrical performance. Current rating reduction from 15A to 12A must be evaluated against application requirements; substitutes are suitable for applications rated at 12A or below.

Frequently Asked Questions (FAQ)

Q: Can 1753673 or 1755626 be used as direct replacements for ELFH14290?

A: Yes, both parts are electrically and mechanically compatible. The 0.08mm pitch difference is within acceptable tolerance for terminal block headers. Verify that your application current requirement does not exceed 12A, as substitute parts are rated at 12A UL versus 15A UL for the main part.

Q: What is the difference between 1753673 and 1755626?

A: Both parts are identical except for shrouding configuration. Part 1753673 features 2-side shrouding (matching ELFH14290), while 1755626 features 4-side shrouding. Select based on your PCB layout and mechanical clearance requirements.

Q: Are there any compliance differences between the main part and substitutes?

A: The main part is RoHS Compliant, while substitutes are ROHS3 Compliant. Both meet UL94 V-0 flammability requirements and carry MSL 1 (Unlimited) ratings. All parts are suitable for applications requiring RoHS compliance.

Q: Does the pitch difference of 0.08mm affect compatibility?

A: No. The pitch difference between 5.08mm (ELFH14290) and 5.00mm (substitutes) is within standard mechanical tolerances for terminal block headers and does not affect electrical performance or mating compatibility.

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

A: The main part is rated at 15A UL, while substitutes are rated at 12A UL. If your application operates at 12A or below, substitutes are fully suitable. For applications requiring 15A operation, the main part ELFH14290 is required.

Q: Can I use the 4-side shrouded version (1755626) in place of the 2-side shrouded version (1753673)?

A: Electrically yes, but verify PCB footprint compatibility. The 4-side shrouding increases the mechanical envelope and may require additional clearance on the PCB. Consult your PCB layout documentation before substitution.
