ELFH20160 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH20160 is a 20-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 2-side shrouding and is rated for 15A at 300V UL. The part is currently active in production with 1071 units in stock.

Alternative models become necessary when specific sourcing constraints exist, such as inventory limitations, regional availability, or when design requirements permit substitution within defined electrical and mechanical tolerances.

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH20160 is determined by the following critical parameters:

Position Count: Must equal 20 positions
Pitch Tolerance: 0.197" (5.00mm) nominal, with 0.200" (5.08mm) acceptable within standard manufacturing tolerances for terminal block headers
Orientation: Vertical mounting only
Shrouding Configuration: 2-side shrouding preferred; 4-side shrouding acceptable as a more protective alternative
Voltage Rating: Minimum 300V UL compliance required
Current Rating: Minimum 12A required; 15A preferred
Flammability: UL94 V-0 compliance mandatory
Termination: Solder termination required
Mounting: Through-hole only

The substitute parts listed below meet these criteria within acceptable engineering tolerances for terminal block header applications.

Engineering Selection Recommendations

Both Phoenix Contact substitutes (1755914 and 1758199) are active products with current manufacturing support and full RoHS3 compliance. Selection between alternatives depends on specific application requirements:

1758199 (Phoenix Contact COMBICON MSTBV) maintains the 2-side shrouding configuration identical to the ELFH20160, making it the primary substitute for direct form-fit-function replacement. This part carries 993 units in current inventory.

1755914 (Phoenix Contact COMBICON MSTBVA) provides 4-side shrouding, offering enhanced mechanical protection and isolation. This configuration is suitable for applications where increased shrouding is beneficial. This part carries 1142 units in current inventory.

Both substitutes operate within the specified voltage and current parameters. The pitch variance of 0.003" (0.08mm) between the ELFH20160 and Phoenix Contact parts falls within standard manufacturing tolerances for terminal block headers and does not affect PCB layout compatibility for typical applications.

Frequently Asked Questions (FAQ)

Q: Can 1758199 or 1755914 be used as direct replacements for ELFH20160?

A: Yes, both parts are functionally equivalent within the electrical and mechanical parameters specified for this product category. The 0.003" pitch difference is within standard terminal block manufacturing tolerances and does not affect PCB footprint compatibility.

Q: What is the difference between 1755914 and 1758199?

A: Both are Phoenix Contact 20-position vertical terminal block headers with 5.08mm pitch. The primary difference is shrouding configuration: 1755914 features 4-side shrouding, while 1758199 features 2-side shrouding matching the ELFH20160 design.

Q: Are there any compliance differences between the main part and substitutes?

A: The ELFH20160 is RoHS Compliant. Both substitutes (1755914 and 1758199) are ROHS3 Compliant, which represents a more current compliance standard. All three parts meet UL94 V-0 flammability requirements and operate within 300V UL voltage ratings.

Q: Does the current rating difference (15A vs 12A) affect substitution?

A: The ELFH20160 is rated for 15A UL, while both Phoenix Contact substitutes are rated for 12A UL. For applications requiring the full 15A capacity, the ELFH20160 is the appropriate selection. For applications operating at or below 12A, either substitute is acceptable.

Q: What are the packaging differences?

A: The ELFH20160 is supplied in Tray packaging. Both Phoenix Contact substitutes (1755914 and 1758199) are supplied in Bulk packaging. Packaging format does not affect component functionality or electrical performance.
