ELFH20150 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH20150 is a 20-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 708 units in stock.

Terminal block headers of this type are essential in industrial control systems, power distribution modules, and signal routing applications where reliable electrical connections and mechanical stability are required. Equivalent and substitute parts may be necessary due to supply chain constraints, design revisions, or specific application requirements that demand alternative electrical or mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH20150 is determined by the following critical parameters:

• Position Count: Must be 20 positions to maintain PCB layout compatibility
• Pitch Tolerance: Nominal pitch of 5.00mm (0.197") allows for minor pitch variations (5.08mm / 0.200") within standard manufacturing tolerances, provided the connector footprint remains compatible with the receiving PCB
• Mounting Configuration: Must be vertical through-hole to match assembly process and mechanical orientation
• Electrical Ratings: Substitute parts must meet or exceed 300V voltage rating and 12A minimum current rating for safe operation in equivalent applications
• Termination Method: Solder termination is required for PCB assembly compatibility
• Shrouding: Both 4-side and 2-side shrouded configurations are acceptable, as shrouding serves primarily to prevent accidental contact and does not affect electrical performance
• Housing Material: PBT and Polyamide (PA/Nylon) are both acceptable thermoplastic materials meeting UL94 V-0 flammability requirements
• Compliance: RoHS compliance is required for applications subject to EU regulations

The Phoenix Contact 1758199 qualifies as a substitute based on these parameters.

Engineering Selection Recommendations

Primary Selection (ELFH20150)

The ELFH20150 remains the preferred choice for new designs and direct replacement applications. It is actively manufactured, RoHS compliant, and carries a higher UL current rating of 15A, providing additional margin in high-current applications. The 4-side shrouding offers enhanced protection against accidental contact.

Substitute Selection (1758199)

The Phoenix Contact 1758199 is suitable as an equivalent substitute when the ELFH20150 is unavailable. Both parts meet the same UL voltage requirement of 300V and maintain electrical compatibility at 12A operation. The 1758199 carries ROHS3 compliance, confirming adherence to current RoHS regulations. The 2-side shrouding is functionally equivalent for electrical isolation purposes. The 5.08mm pitch represents a minor deviation from the 5.00mm nominal pitch; PCB layout compatibility must be confirmed before substitution.

Both parts are active products with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 1758199 be used as a direct drop-in replacement for the ELFH20150?

A: The 1758199 is electrically and mechanically compatible for most applications. However, the pitch difference (5.08mm vs. 5.00mm) requires verification that the receiving PCB footprint accommodates this tolerance. The reduced UL current rating (12A vs. 15A) is acceptable for applications operating below 12A.

Q: What is the significance of the pitch difference between 5.00mm and 5.08mm?

A: The 0.08mm difference falls within standard manufacturing tolerances for terminal block connectors. Both pitches are industry-standard spacing. PCB footprint compatibility must be confirmed; most modern PCB designs accommodate both pitches within their tolerance stack-up.

Q: Are there differences in shrouding between these parts?

A: The ELFH20150 features 4-side shrouding, while the 1758199 has 2-side shrouding. Both configurations provide electrical isolation and prevent accidental contact. The 4-side design offers slightly enhanced mechanical protection; the 2-side design is functionally equivalent for electrical performance.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant (ELFH20150 is RoHS Compliant; 1758199 is ROHS3 Compliant). Both achieve UL94 V-0 flammability rating. The 1758199 carries additional REACH Unaffected status. Both are suitable for regulated applications.

Q: What is the current rating difference, and does it affect substitution?

A: The ELFH20150 is rated for 15A (UL), while the 1758199 is rated for 12A (UL). For applications operating at or below 12A, the 1758199 is fully suitable. For applications requiring the full 15A capacity, the ELFH20150 is required.

Q: Are the housing materials interchangeable?

A: The ELFH20150 uses PBT (Polybutylene Terephthalate), while the 1758199 uses PA/Nylon (Polyamide). Both materials meet UL94 V-0 flammability requirements and are suitable for the same operating temperature range. Material selection depends on specific environmental exposure; both are acceptable for standard industrial applications.
