ELFH02180 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH02180 is a 2-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 5.00mm pitch spacing. This component is classified as a shrouded male pin header with solder termination, rated for 15A at 300V (UL). The part is currently active in production with 1086 units in stock.

Terminal block headers require substitute evaluation when original stock is unavailable, when alternative sourcing reduces lead times, or when design flexibility permits equivalent components from qualified manufacturers. Substitutes must maintain electrical performance, mechanical compatibility, and regulatory compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH02180 is determined by the following critical parameters:

• Position Count & Pitch: Substitute must have 2 positions with 0.197" (5.00mm) pitch to ensure PCB footprint compatibility
• Orientation & Mounting: Vertical through-hole mounting is required for mechanical fit
• Electrical Ratings: Substitute must meet or exceed 15A current and 300V voltage ratings under UL classification
• Termination: Solder termination is mandatory for assembly process compatibility
• Regulatory Compliance: UL94 V-0 flammability rating and RoHS compliance are required

The Phoenix Contact 1753437 qualifies as a substitute based on these parameters. Both components share identical position count, pitch, orientation, mounting type, and termination method. Both meet UL94 V-0 flammability requirements and maintain RoHS compliance. Electrical ratings are compatible within the application envelope.

Engineering Selection Recommendations

Primary Selection: ELFH02180 (Amphenol PCD)

The ELFH02180 remains the preferred component when available. It provides 15A current capacity under UL rating, full 4-side shrouding for enhanced EMI shielding and mechanical protection, and active production status with established supply chain.

Substitute Selection: 1753437 (Phoenix Contact)

The Phoenix Contact 1753437 is electrically and mechanically compatible for applications where the 12A UL current rating is sufficient. This substitute is appropriate when:

• Circuit design operates below 12A continuous current
• 2-side shrouding provides adequate mechanical protection for the application
• Lead time or cost considerations justify the substitution
• ROHS3 compliance meets or exceeds project requirements

Both components maintain identical pitch, position count, voltage rating, and flammability classification. The primary design consideration is current capacity and shrouding configuration.

Frequently Asked Questions (FAQ)

Q: Can the 1753437 be used in place of ELFH02180 in all applications?

A: The 1753437 is suitable for applications where the circuit current does not exceed 12A. If your design requires the full 15A capacity of the ELFH02180, the substitute is not appropriate. Verify your actual current requirements before substitution.

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

A: 4-side shrouding (ELFH02180) provides complete enclosure around the header pins, offering superior EMI shielding and mechanical protection. 2-side shrouding (1753437) covers only two sides. For applications with EMI sensitivity or harsh mechanical environments, 4-side shrouding is preferred.

Q: Are the PCB footprints identical?

A: Yes. Both components have 2 positions with 0.197" (5.00mm) pitch and vertical through-hole mounting. PCB footprints are interchangeable.

Q: Do both parts meet the same regulatory standards?

A: Both components are UL94 V-0 rated and RoHS compliant. The ELFH02180 is RoHS Compliant; the 1753437 is ROHS3 Compliant. Both meet current regulatory requirements.

Q: What is the voltage rating difference?

A: The ELFH02180 is rated 300V (UL). The 1753437 is rated 300V (UL) and 400V (IEC). Both meet the 300V requirement for standard applications.

Q: Can I mix these components on the same PCB?

A: Yes. Both components are mechanically and electrically compatible for mixed-use designs, provided individual circuit branches respect the 12A limit for branches using the 1753437.
