ELFH18180 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH18180 is an 18-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 5.00mm pitch spacing. This component is classified as a shrouded male pin header suitable for industrial control and signal distribution applications. The part is currently active in production with 928 units in stock. Alternative equivalent parts may be required due to supply chain considerations, packaging preferences, or specific application requirements where substitute components meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH18180 is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: 18 positions at 0.197" (5.00mm) spacing
• Header Configuration: Male pins with 4-side shrouding
• Mounting Method: Vertical through-hole solder termination
• Electrical Ratings: Minimum 300 V UL voltage rating and 12 A minimum current capacity
• Flammability Compliance: UL94 V-0 material rating
• Environmental Compliance: RoHS compliance status

The substitute part 1755668 (Phoenix Contact COMBICON MSTBVA series) meets all critical substitution criteria. Both components share identical position count, pitch spacing, header type, orientation, and termination method. Both maintain UL94 V-0 flammability compliance and RoHS compliance status. Electrical ratings remain within acceptable operating parameters for equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the ELFH18180 and 1755668 are active production components with current inventory availability. Selection between these parts is based on application-specific requirements and supply chain factors:

ELFH18180 (Amphenol PCD) is suitable for applications requiring the full 15 A UL current rating and black housing color specification. RoHS compliance is confirmed.

1755668 (Phoenix Contact) is suitable for applications where the 12 A UL current rating is sufficient and green housing color is acceptable or preferred. ROHS3 compliance provides extended regulatory coverage. Bulk packaging may be advantageous for high-volume procurement.

Both components satisfy identical electrical, mechanical, and environmental specifications for standard terminal block header applications operating within the specified voltage and current parameters. Component selection should be based on current availability, packaging requirements, and specific application current demands.

Frequently Asked Questions (FAQ)

Q: Can 1755668 replace ELFH18180 in all applications?

A: The 1755668 is electrically and mechanically compatible with the ELFH18180 for applications requiring 12 A or less at 300 V UL rating. Applications requiring the full 15 A capacity must use the ELFH18180.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both designations indicate RoHS compliance. ROHS3 represents compliance with the most current RoHS directive revision. Both parts meet hazardous substance restrictions for electronic components.

Q: Does the color difference (black vs. green) affect functionality?

A: No. Color is a cosmetic specification only and does not affect electrical performance, mechanical fit, or thermal characteristics. Selection should be based on application aesthetics or internal documentation requirements.

Q: What is the significance of packaging differences (Tray vs. Bulk)?

A: Packaging affects component handling, storage, and procurement logistics but not electrical or mechanical performance. Tray packaging provides individual component protection; bulk packaging is typically used for high-volume orders.

Q: Are both parts suitable for the same PCB footprint?

A: Yes. Both components share identical pitch spacing (5.00mm), position count (18), and through-hole mounting configuration, making them mechanically interchangeable on standard PCB layouts.

Q: What is MSL 1 (Unlimited) significance?

A: MSL 1 indicates the component has unlimited shelf life under normal storage conditions and requires no special moisture control during handling or storage.
