ELFH09250E Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH09250E is a 9-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 active in production and RoHS compliant, making it suitable for modern electronic assemblies requiring reliable interconnection solutions.

Alternative models may be required due to inventory constraints, regional supplier availability, or specific application requirements for enhanced voltage or current ratings.

Substitute Part Grouping Explanation

The Phoenix Contact 1777141 qualifies as a direct substitute based on the following critical parameters:

Electrical Compatibility: Both components maintain 300V UL voltage rating and support 9-position configuration at 0.200" (5.08mm) pitch
Mechanical Compatibility: Identical vertical through-hole mounting orientation with shrouded 4-side male pin design
Material & Safety: Both utilize PBT housing with UL94 V-0 flammability rating
Termination Method: Both employ solder termination for PCB integration
Compliance: Both are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity rating

The Phoenix Contact substitute operates at 12A UL current (versus 15A for the ELFH09250E) and features enhanced mechanical design with both mating and mounting flanges. The substitute is suitable for applications where the 12A current rating is acceptable within the circuit design parameters.

Engineering Selection Recommendations

Both components are active production items with current compliance certifications. The ELFH09250E provides 15A UL current capacity, while the Phoenix Contact 1777141 operates at 12A UL. Selection between these components depends on circuit current requirements:

ELFH09250E: Select when circuit design requires the full 15A UL current rating
1777141: Select when circuit current does not exceed 12A UL and enhanced mechanical features (mating and mounting flanges) provide design advantages

Both components meet UL94 V-0 flammability requirements and maintain identical electrical isolation at 300V UL. The Phoenix Contact substitute includes additional mechanical flanges for improved mounting stability. Voltage and pitch specifications are identical, ensuring direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1777141 be used as a direct replacement for ELFH09250E?

A: Yes, provided the circuit current requirement does not exceed 12A UL. Both components share identical pitch (5.08mm), position count (9), voltage rating (300V UL), mounting orientation (vertical through-hole), and housing material (PBT UL94 V-0). The primary difference is the current rating: ELFH09250E supports 15A UL while 1777141 supports 12A UL.

Q: What are the key compatibility criteria for these terminal block headers?

A: Compatibility is determined by: number of positions (9), pitch spacing (0.200"/5.08mm), header type (male pins, shrouded 4-side), mounting method (vertical through-hole solder), voltage rating (300V UL minimum), and housing material (PBT). Both components meet these criteria.

Q: Are there differences in mechanical mounting between these components?

A: The Phoenix Contact 1777141 features both mating and mounting flanges, while the ELFH09250E includes a mating flange. Both are designed for through-hole PCB mounting with solder termination. The additional mounting flange on the substitute may provide enhanced mechanical stability in vibration-prone applications.

Q: Do both components have the same moisture sensitivity rating?

A: Yes. Both the ELFH09250E and 1777141 carry MSL 1 (Unlimited) moisture sensitivity level, indicating no special moisture control requirements during storage or handling.

Q: What compliance certifications apply to both components?

A: Both components are RoHS compliant (ELFH09250E: RoHS Compliant; 1777141: ROHS3 Compliant) and carry UL94 V-0 flammability ratings. Both are active production items suitable for current industrial applications.
