ELFH12180 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH12180 is a 12-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 5.00mm pitch spacing. This component features male pins with 4-side shrouding, rated for 15A at 300V UL, and operates across -40°C to 105°C. The part is active in production and RoHS compliant. Equivalent and substitute parts are identified based on matching electrical ratings, mechanical dimensions, and functional compatibility within the terminal block header category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters: 12-position count, vertical orientation, through-hole mounting, solder termination, and UL94 V-0 flammability rating. Pitch tolerance is the primary differentiator among candidates. The ELFH12180 operates at 5.00mm pitch (0.197"), which is the IEC standard. Substitute parts at 5.08mm pitch (0.200") represent a minor dimensional variance within acceptable mechanical tolerance for many applications but require verification of PCB layout compatibility. Shrouding configuration (2-side vs. 4-side) and housing material composition are secondary considerations that do not prevent functional substitution when electrical and positional requirements align.

Parameter Comparison

Engineering Selection Recommendations

0395316012 (Molex Eurostyle ESE 39531): This part matches the ELFH12180 in current rating (15A), voltage (300V), operating temperature range (-40°C to 105°C), and flammability classification (UL94 V-0). The primary difference is pitch spacing at 5.08mm versus 5.00mm. Both parts are active products with ROHS3 compliance. Selection of this substitute requires PCB layout verification to accommodate the 0.08mm pitch difference across 12 positions (approximately 0.96mm total span variance).

1753631 (Phoenix Contact COMBICON MSTBV): This part shares the 5.00mm pitch and vertical orientation with the ELFH12180 but features 2-side shrouding instead of 4-side. Current rating is reduced to 12A. Voltage rating remains 300V UL. Material flammability is UL94 V-0. This part is suitable for applications where the lower current rating is acceptable and mechanical space constraints favor reduced shrouding. ROHS3 compliance is confirmed.

1755833 (Phoenix Contact COMBICON MSTBVA): This part provides 4-side shrouding matching the ELFH12180 configuration but operates at 5.08mm pitch with reduced current rating (12A). Voltage rating is 300V UL, and flammability classification is UL94 V-0. ROHS3 compliance is confirmed. Selection requires PCB layout compatibility verification for the pitch variance and current derating assessment.

All substitute parts maintain UL94 V-0 flammability rating, solder termination, and through-hole mounting compatibility. Product status is active for all candidates, ensuring continued availability.

Frequently Asked Questions (FAQ)

Q: Can I use a 5.08mm pitch part as a direct replacement for the 5.00mm pitch ELFH12180?

A: Mechanical substitution is possible only if PCB layout accommodates the pitch variance. Across 12 positions, the cumulative spacing difference is approximately 0.96mm. Verify that connector footprints and adjacent component placement allow this tolerance before selection.

Q: What is the impact of using a 12A-rated substitute instead of the 15A ELFH12180?

A: The 12A rating of Phoenix Contact parts (1753631, 1755833) represents a 20% current derating. Application circuits must operate within 12A maximum to maintain safety margins and component reliability. Verify actual circuit current draw before substitution.

Q: Does shrouding configuration affect electrical performance?

A: Shrouding (2-side vs. 4-side) is a mechanical feature that provides EMI shielding and mechanical protection. Both configurations maintain equivalent electrical performance at the specified voltage and current ratings. Selection depends on application requirements for mechanical robustness and EMI considerations.

Q: Are all substitute parts RoHS compliant?

A: Yes. The ELFH12180 is RoHS Compliant, and all substitute parts carry ROHS3 Compliant certification, confirming compliance with current restricted substance directives.

Q: What is the moisture sensitivity level for these parts?

A: All parts, including the ELFH12180 and all substitutes, are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can I mix ELFH12180 and substitute parts in the same assembly?

A: Yes, provided the application circuit accommodates any current or pitch differences. Mixing parts with different pitch specifications requires careful PCB layout planning to avoid mechanical misalignment or electrical discontinuity.
