ELFH15250E Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH15250E is a 15-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 0.200" (5.08mm) pitch spacing. This shrouded male pin header operates at 300V UL and 15A UL current rating, suitable for industrial control and signal distribution applications. The component is actively produced and RoHS compliant, making it a standard choice for PCB-to-wire interconnection in control systems.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and mounting characteristics are maintained across the critical parameters that define functional interchangeability.

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH15250E is determined by strict equivalence in the following parameters:

Position Count & Pitch: 15 positions at 0.200" (5.08mm) spacing (mechanical compatibility with mating connectors)
Header Type & Orientation: Male pins, shrouded (4-side), vertical mounting (form factor and PCB footprint match)
Termination & Mounting: Solder termination, through-hole mounting (assembly process compatibility)
Electrical Ratings: Voltage and current ratings must meet or exceed UL 300V / 15A specification
Flammability & Compliance: UL94 V-0 material rating and RoHS compliance (regulatory and safety requirements)

The Phoenix Contact 1777206 meets these core substitution criteria with identical mechanical configuration and equivalent electrical performance within the specified operating envelope.

Engineering Selection Recommendations

Both the ELFH15250E and 1777206 are active production components with equivalent mechanical compatibility and UL voltage rating (300V). Selection between these parts should be based on the following factors:

ELFH15250E (Amphenol PCD): Specified for 15A UL current rating. Use when maximum current capacity at UL specification is required. Lower insulation height (8.10mm) may be advantageous in space-constrained PCB layouts.

1777206 (Phoenix Contact): Specified for 12A UL current rating with additional IEC rating of 12A at 630V. Use when IEC compliance is required or when the 12A current rating is sufficient for the application. Higher insulation height (12.00mm) provides additional creepage distance. ROHS3 compliance indicates compliance with the latest RoHS directive iteration.

Both components maintain UL94 V-0 flammability rating and tin-plated contacts. Footprint compatibility is assured by identical pitch and position count, though the difference in insulation height should be verified against PCB clearance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1777206 directly replace the ELFH15250E on existing PCBs?

A: Mechanical footprint compatibility is assured by identical 15-position, 0.200" (5.08mm) pitch configuration and vertical through-hole mounting. However, the 1777206 has a higher insulation height (12.00mm vs. 8.10mm), which may affect clearance to adjacent components or PCB features. Verify clearance before substitution.

Q: What is the current rating difference between these parts?

A: The ELFH15250E is rated for 15A UL, while the 1777206 is rated for 12A UL. If the application requires current above 12A, the ELFH15250E must be used. For applications at or below 12A, both parts are suitable.

Q: Are both parts RoHS compliant?

A: Yes. The ELFH15250E is RoHS Compliant. The 1777206 is ROHS3 Compliant, indicating compliance with the most recent RoHS directive requirements.

Q: What is the significance of the different insulation heights?

A: Insulation height affects creepage distance and PCB layout clearance. The ELFH15250E (8.10mm) is more compact, while the 1777206 (12.00mm) provides greater creepage distance, which may be required in high-voltage or high-reliability applications. Verify PCB design requirements before selection.

Q: Do both parts have the same contact material?

A: Both use tin-plated contacts. The ELFH15250E specifies brass contact material; the 1777206 contact material is not specified in the provided data.

Q: What is the operating temperature range?

A: The ELFH15250E operates from -40°C to 105°C. Operating temperature for the 1777206 is not specified in the provided data.
