ELFH18150 Equivalent & Substitute Parts

Part Overview

The ELFH18150 is an 18-position terminal block header manufactured by Amphenol PCD. This component features male pins with 4-side shrouding, a 0.197" (5.00mm) pitch, and vertical through-hole mounting. The part is rated for 15 A (UL) at 300 V (UL) and operates across -40°C to 105°C. It is currently in active production status with RoHS compliance and MSL 1 rating.

Finding equivalent and substitute parts is necessary to ensure supply chain flexibility, manage inventory across multiple suppliers, and maintain design continuity when the primary part becomes unavailable or when alternative sourcing offers cost or logistics advantages.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH18150 is determined by the following critical parameters:

• 18-position configuration with single level
• 0.197" (5.00mm) pitch spacing
• Vertical orientation with through-hole solder termination
• Male pin header with 4-side shrouding
• Voltage rating of 300 V (UL) minimum
• Current rating of 12 A (IEC) or 12 A (UL) minimum
• UL94 V-0 flammability rating
• RoHS compliance status

The substitute part 1755668 (Phoenix Contact COMBICON MSTBVA series) meets these core electrical and mechanical requirements, enabling direct functional substitution in applications where the ELFH18150 is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the ELFH18150 and 1755668 are active production parts with full RoHS compliance and MSL 1 ratings, ensuring long-term availability and environmental regulatory compliance. The ELFH18150 offers a 15 A UL current rating compared to the 1755668's 12 A UL rating; applications requiring the full 15 A capacity should retain the primary part. The 1755668 provides IEC certification at 400 V, offering additional international standards coverage. Housing material differs (PBT versus PA/Nylon), which may affect mechanical properties in specific thermal or chemical environments. Both parts maintain identical pitch, position count, shrouding configuration, and solder termination, ensuring mechanical and electrical compatibility at the PCB interface.

Frequently Asked Questions (FAQ)

Q: Can the 1755668 be used as a direct replacement for the ELFH18150?

A: Yes, for applications operating at or below 12 A (UL) and 300 V (UL). The 1755668 meets all core mechanical and electrical requirements: 18 positions, 5.00mm pitch, vertical through-hole solder termination, 4-side shrouding, and UL94 V-0 flammability rating. Applications requiring the full 15 A capacity of the ELFH18150 should not substitute.

Q: What are the differences in housing material between these parts?

A: The ELFH18150 uses Polybutylene Terephthalate (PBT), while the 1755668 uses Polyamide (PA) and Nylon. Both materials meet UL94 V-0 flammability requirements. Material selection may affect performance in extreme temperature, chemical exposure, or mechanical stress scenarios specific to the application environment.

Q: Are both parts RoHS compliant?

A: Yes. The ELFH18150 is RoHS Compliant, and the 1755668 is ROHS3 Compliant. Both meet current environmental regulations for restricted substances.

Q: What is the packaging difference?

A: The ELFH18150 is supplied in Tray packaging, while the 1755668 is supplied in Bulk packaging. Packaging format may affect inventory management, handling, and cost per unit but does not impact electrical or mechanical performance.

Q: Does the color difference (Black vs. Green) affect functionality?

A: No. Color is a cosmetic distinction and does not affect electrical performance, mechanical compatibility, or thermal characteristics. Selection should be based on application requirements and visual identification needs.

Q: What is the contact tail length difference?

A: The ELFH18150 does not specify contact tail length, while the 1755668 specifies 0.154" (3.90mm). This parameter affects solder joint geometry and PCB pad design. Verify PCB layout compatibility if switching between parts.
