Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1755671 qualifies as a direct substitute for the ELFH19150 based on the following critical parameters:

• Position Count & Pitch: Both components feature 19 positions with identical 0.197" (5.00mm) pitch spacing, ensuring mechanical and electrical compatibility in PCB layouts and mating connector designs.
• Header Configuration: Both are vertical-mount, through-hole, male-pin headers with 4-side shrouding, maintaining identical form factor and mounting footprint.
• Termination Method: Both use solder termination, compatible with standard PCB assembly processes.
• Electrical Ratings: The substitute meets or exceeds the main part's UL voltage rating (300 V) and current capacity (12 A UL vs. 15 A UL for main part), satisfying electrical performance requirements.
• Compliance Standards: Both components carry UL94 V-0 flammability certification and RoHS compliance, meeting regulatory requirements for industrial applications.
• Moisture Sensitivity: Both are classified as MSL 1 (Unlimited), indicating no moisture-related handling restrictions.

Parameter Comparison

Engineering Selection Recommendations

Both the ELFH19150 and 1755671 are active products with current manufacturing status, ensuring long-term availability and supply chain stability. Selection between these components should be based on:

• Inventory Availability: The ELFH19150 has 757 units in stock, while the 1755671 has 1150 units available, providing flexibility in procurement timing.
• Compliance Requirements: Both components meet UL94 V-0 flammability standards and RoHS compliance requirements. The 1755671 carries ROHS3 certification, indicating compliance with the latest RoHS directive revision.
• Electrical Performance: The ELFH19150 supports 15 A at UL ratings, while the 1755671 supports 12 A. Applications requiring current levels between 12 A and 15 A should use the ELFH19150. Applications operating at or below 12 A are compatible with either component.
• Regulatory Certifications: Both components carry ECCN EAR99 classification and identical HTSUS codes (8536.69.4040), confirming equivalent regulatory treatment for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1755671 be used as a direct replacement for the ELFH19150 in existing designs?

A: Yes, the 1755671 is mechanically and electrically compatible for applications operating at 12 A or below. The identical pitch (5.00mm), position count (19), orientation (vertical), and mounting type (through-hole solder) ensure PCB footprint compatibility. Applications requiring the full 15 A UL rating of the ELFH19150 should retain the original component.

Q: What are the key differences between these two components?

A: The primary differences are manufacturer (Amphenol PCD vs. Phoenix Contact), housing material (PBT vs. Polyamide/Nylon), color (Black vs. Green), and UL current rating (15 A vs. 12 A). All other critical electrical and mechanical parameters are identical.

Q: Are there any packaging or handling differences?

A: The ELFH19150 is supplied in Tray packaging, while the 1755671 is supplied in Bulk packaging. Both components have MSL 1 (Unlimited) moisture sensitivity classification, requiring no special moisture-control handling during storage or assembly.

Q: Do both components meet the same compliance standards?

A: Both components are UL94 V-0 rated and RoHS compliant. The 1755671 carries ROHS3 certification, representing the current RoHS directive revision. Both are classified as EAR99 for export control purposes and share identical HTSUS tariff codes.

Q: Which component should be selected for new designs?

A: Selection should be based on current availability, lead times, and application current requirements. For applications requiring 12 A or less, either component is suitable. For applications requiring 15 A, the ELFH19150 is the appropriate choice. Both are active products with stable supply chains.
