ELFH05280 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH05280 is a 5-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 5.08mm pitch spacing. This shrouded header features male pins and is rated for 15A at 300V (UL). The component is actively produced and stocked with 874 units available. Terminal block headers of this specification are essential in applications requiring reliable electrical interconnection with standardized pitch and current-carrying capacity. Substitute parts may be required due to supply constraints, packaging preferences, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH05280 is determined by the following critical parameters:

• Position Count & Pitch: Substitute parts must have 5 positions with 0.200" (5.08mm) pitch spacing to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Header Type & Orientation: Vertical orientation with male pins is required for direct functional replacement.
• Mounting & Termination: Through-hole solder termination must be maintained.
• Electrical Ratings: Substitute parts must meet or exceed the UL voltage rating of 300V. Current rating of 15A (UL) establishes the minimum acceptable performance threshold.
• Shrouding Configuration: The ELFH05280 features 4-side shrouding. Substitute parts with reduced shrouding (2-side) may be considered acceptable if electrical and mechanical parameters align, though shrouding differences should be evaluated for specific application requirements.
• Compliance & Material: RoHS compliance and UL94 V-0 flammability rating are baseline requirements.

The substitute part 1758047 (Phoenix Contact COMBICON MSTBV series) meets these criteria with equivalent position count, pitch, orientation, and termination style, though with 2-side shrouding and slightly different electrical ratings under IEC standards.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (ELFH05280): Recommended for applications requiring 4-side shrouding and 15A current capacity. Active production status and RoHS compliance ensure long-term availability and regulatory compliance.

Substitute Part (1758047): Acceptable as an alternative when supply of the primary part is constrained. The Phoenix Contact COMBICON MSTBV series maintains electrical compatibility at 300V UL rating and meets UL94 V-0 flammability requirements. The 12A UL current rating is lower than the primary part; applications requiring the full 15A capacity should not use this substitute. The 2-side shrouding configuration differs from the 4-side design of the ELFH05280 and should be evaluated for mechanical fit and EMI considerations in the target application. ROHS3 compliance exceeds the RoHS requirement of the primary part.

Selection between these parts should be based on current capacity requirements, shrouding specifications, and packaging preferences (tray vs. bulk).

Frequently Asked Questions (FAQ)

Q: Can the 1758047 directly replace the ELFH05280 in all applications?

A: Direct replacement is possible for applications operating at or below 12A. The 2-side shrouding of the 1758047 differs from the 4-side shrouding of the ELFH05280; mechanical fit and EMI performance should be evaluated for the specific application.

Q: What is the significance of the shrouding difference (4-side vs. 2-side)?

A: Shrouding provides mechanical protection and EMI shielding. The ELFH05280 offers full 4-side shrouding, while the 1758047 provides 2-side shrouding. The choice depends on application requirements for mechanical robustness and electromagnetic compatibility.

Q: Are both parts RoHS compliant?

A: Yes. The ELFH05280 is RoHS Compliant, and the 1758047 is ROHS3 Compliant. Both meet RoHS requirements.

Q: What is the difference in current ratings between these parts?

A: The ELFH05280 is rated for 15A (UL), while the 1758047 is rated for 12A (UL). Applications requiring currents above 12A must use the ELFH05280.

Q: Does packaging type affect electrical performance?

A: No. Packaging (tray vs. bulk) affects handling, storage, and ordering logistics but does not affect electrical or mechanical performance of the terminal block header itself.

Q: Are the contact tail lengths compatible?

A: Contact tail lengths are nearly identical: ELFH05280 at 0.155" (3.94mm) and 1758047 at 0.154" (3.90mm). This minimal difference does not affect PCB soldering or mechanical compatibility.
