ELFH14250 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The ELFH14250 is a 14-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 5.08mm pitch spacing. This shrouded (4-side) header features male pins and solder termination, rated for 15A at 300V UL specifications. The component is actively produced and RoHS compliant, making it suitable for industrial control, power distribution, and signal routing applications requiring reliable multi-position connectivity.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the 14-position, vertical orientation, and solder termination requirements, despite minor variations in pitch tolerance and shroud configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Position Count: Must equal 14 positions
• Pitch Tolerance: 5.08mm (0.200") primary; 5.00mm (0.197") acceptable within 0.08mm tolerance
• Orientation: Vertical through-hole mounting required
• Termination: Solder termination mandatory
• Shroud Configuration: 4-side shroud preferred; 2-side shroud acceptable with mechanical verification
• Electrical Ratings: Minimum 12A current and 300V voltage at UL specifications
• Compliance: RoHS and UL94 V-0 flammability rating required

The identified substitutes (1755626 and 1753673) meet these criteria with minor pitch variation (5.00mm vs. 5.08mm) and shroud configuration differences that remain functionally compatible for standard PCB mounting applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 1755626 (Phoenix Contact COMBICON MSTBVA)

Part 1755626 provides the closest functional equivalence to ELFH14250. Both components feature 4-side shroud configuration, identical 14-position count, vertical through-hole mounting, and solder termination. The 0.08mm pitch variation (5.00mm vs. 5.08mm) falls within standard PCB layout tolerance for connector footprints. Both parts maintain UL94 V-0 flammability compliance and unlimited moisture sensitivity rating. The 12A UL current rating of 1755626 is lower than the 15A rating of ELFH14250; applications requiring the full 15A capacity must retain the original ELFH14250.

Secondary Substitute: 1753673 (Phoenix Contact COMBICON MSTBV)

Part 1753673 offers functional substitution with the same 14-position, vertical, solder-terminated configuration. The 2-side shroud differs from the 4-side shroud of ELFH14250, reducing EMI shielding effectiveness. This configuration is suitable for applications where full shroud protection is not critical. Like 1755626, the 12A UL current rating applies. Both Phoenix Contact parts carry ROHS3 compliance, exceeding the RoHS compliance of the original part.

Frequently Asked Questions (FAQ)

Q: Can 1755626 be used as a direct replacement for ELFH14250 in all applications?

A: 1755626 is functionally compatible for most applications. The primary limitation is current capacity: 1755626 is rated for 12A versus ELFH14250's 15A. Applications operating at currents between 12A and 15A require the original ELFH14250. The 0.08mm pitch difference is accommodated by standard PCB connector footprint tolerances.

Q: What is the difference between the 4-side and 2-side shroud configurations?

A: The 4-side shroud (ELFH14250 and 1755626) provides complete perimeter shielding, reducing crosstalk and EMI. The 2-side shroud (1753673) provides partial shielding on two opposing sides. For applications requiring maximum EMI protection, the 4-side shroud configuration is preferred.

Q: Are the pitch differences between 5.08mm and 5.00mm significant for PCB layout?

A: The 0.08mm difference represents approximately 1.6% variation. Standard PCB connector footprints accommodate this tolerance range. However, PCB layout files should be verified to confirm the footprint accepts both pitch specifications before component substitution.

Q: Do all three parts meet the same compliance standards?

A: All three parts are UL94 V-0 flammable rated and carry unlimited moisture sensitivity (MSL 1). ELFH14250 is RoHS compliant; 1755626 and 1753673 are ROHS3 compliant, which represents a more stringent standard. All parts are suitable for applications requiring RoHS compliance.

Q: What housing material differences exist between the parts?

A: ELFH14250 uses Polybutylene Terephthalate (PBT); 1755626 and 1753673 use Polyamide (PA) Nylon. Both materials meet UL94 V-0 requirements. PBT offers slightly higher temperature stability; Polyamide offers improved mechanical flexibility. Material selection should be verified against specific application thermal and mechanical requirements.
