ELFH07280 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH07280 is a 7-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 0.200" (5.08mm) pitch spacing. This component features male pins with 4-side shrouding and is rated for 15A at 300V (UL). The part is currently active in production with 723 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 different manufacturers. Substitutes must maintain electrical performance, mechanical compatibility, and compliance certifications to ensure reliable system operation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH07280 is determined by the following critical parameters:

• Position Count: Must be 7 positions to maintain PCB layout compatibility
• Pitch Tolerance: Nominal pitch of 5.00mm to 5.08mm is acceptable; both values represent the same mechanical spacing within standard manufacturing tolerances
• Orientation: Must be vertical through-hole configuration
• Shrouding: Both 2-side and 4-side shrouding designs are mechanically compatible; shrouding type does not affect electrical performance or mating capability
• Electrical Ratings: Substitute must meet or exceed 300V voltage rating; current rating of 12A minimum is acceptable for most applications where 15A is specified, provided system design accounts for the lower rating
• Termination: Solder termination is required for PCB assembly compatibility
• Compliance: RoHS compliance is mandatory; UL94 V-0 flammability rating ensures safety equivalence

The Phoenix Contact 1753534 meets all substitution criteria within these parameters.

Engineering Selection Recommendations

Primary Part (ELFH07280): Select when original design specification requires 15A current capacity, 4-side shrouding, or tray packaging. RoHS compliance and UL94 V-0 rating are confirmed. Active production status ensures long-term availability.

Substitute Part (1753534): Select when design permits 12A current rating and 2-side shrouding configuration. ROHS3 compliance exceeds RoHS requirements. Higher inventory availability (2750 units) supports shorter lead times. Pitch tolerance of 5.00mm versus 5.08mm is within standard PCB design margins for 7-position headers. Bulk packaging may require internal repackaging for production workflows.

Both parts carry identical voltage ratings (300V UL) and flammability certification (UL94 V-0), ensuring equivalent safety performance in end applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1753534 replace the ELFH07280 in existing PCB designs?

A: Yes, provided the design does not require the full 15A current capacity. The 12A rating of the 1753534 is suitable for applications drawing 12A or less. Pitch tolerance (5.00mm vs 5.08mm) is within standard PCB manufacturing tolerances for terminal block headers. Mechanical dimensions (contact tail length and insulation height) are equivalent within tolerance.

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

A: Shrouding refers to the plastic housing that surrounds the pin contacts. 4-side shrouding provides coverage on all four sides; 2-side shrouding covers two opposing sides. Both designs prevent accidental contact and are mechanically compatible with standard mating connectors. Shrouding type does not affect electrical performance or current-carrying capacity.

Q: Are there compliance differences between the two parts?

A: Both parts meet UL94 V-0 flammability requirements and carry RoHS compliance. The ELFH07280 is RoHS Compliant; the 1753534 is ROHS3 Compliant. ROHS3 represents an updated compliance standard and is fully backward compatible with RoHS requirements.

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

A: No. Both pitches represent the same nominal 0.200" spacing within standard manufacturing tolerances. PCB footprints designed for 5.08mm pitch will accommodate 5.00mm pitch components without functional issues.

Q: What packaging considerations apply to the substitute part?

A: The ELFH07280 ships in tray packaging; the 1753534 ships in bulk packaging. Bulk packaging may require internal sorting and repackaging for production assembly lines that expect tray format. Verify packaging compatibility with receiving and assembly procedures before ordering.

Q: Can the 1753534 handle the same voltage as the ELFH07280?

A: Yes. Both parts are rated for 300V (UL), ensuring equivalent voltage performance in applications up to 300V.
