ELFH18160 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH18160 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 with solder termination, suitable for applications requiring secure electrical connections in industrial and commercial equipment. The part maintains Active product status with 849 units in current inventory. Alternative equivalent parts may be required due to supply chain considerations, packaging preferences, or specific application requirements for shrouding configuration or housing material compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH18160 is determined by the following critical parameters:

• Position Count: 18 positions (exact match required)
• Pitch Spacing: 0.197" (5.00mm) (exact match required)
• Header Orientation: Vertical (exact match required)
• Termination Style: Solder (exact match required)
• Mounting Type: Through Hole (exact match required)
• Voltage Rating: Minimum 300 V UL (equal or higher acceptable)
• Current Rating: Minimum 12 A IEC or 12 A UL (equal or higher acceptable)
• Flammability Rating: UL94 V-0 (equal or higher acceptable)
• RoHS Compliance: RoHS or ROHS3 Compliant (both acceptable)

The Phoenix Contact 1755668 qualifies as a functional equivalent based on matching all critical dimensional and electrical parameters. Differences in shrouding configuration (4-side versus 2-side) and housing material (Polyamide versus Polybutylene Terephthalate) represent design variations that do not affect core substitution eligibility when application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

ELFH18160 (Amphenol PCD) remains the primary specification when:

• Original equipment design specifies PBT housing material
• 2-side shrouding configuration is required for mechanical fit
• 15 A current capacity is required for the application
• Amphenol PCD supply chain is preferred or contractually specified

1755668 (Phoenix Contact) is acceptable as a substitute when:

• Application permits Polyamide housing material
• 4-side shrouding configuration is compatible with mechanical design
• 12 A current capacity satisfies application requirements
• Phoenix Contact supply chain availability is advantageous
• ROHS3 compliance meets regulatory requirements

Both parts maintain UL94 V-0 flammability rating and 300 V UL voltage rating, ensuring equivalent safety performance in compliant applications. Selection between these parts should be based on mechanical fit verification, material compatibility with operating environment, and current capacity requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1755668 be used as a direct replacement for the ELFH18160?

A: The 1755668 is functionally equivalent for applications where the 4-side shrouding configuration and Polyamide housing material are compatible with mechanical and environmental requirements. Verify that the application does not specifically require 2-side shrouding or PBT material properties before substitution.

Q: What is the difference between 2-side and 4-side shrouding?

A: 2-side shrouding provides protective barriers on two opposing sides of the header, while 4-side shrouding provides barriers on all four sides. This affects mechanical fit within the PCB assembly and may impact insertion force or connector alignment depending on mating connector design.

Q: Are the current ratings interchangeable?

A: The ELFH18160 is rated for 15 A UL, while the 1755668 is rated for 12 A UL. Substitution is acceptable only when the application current requirement does not exceed 12 A. For applications requiring 15 A capacity, the ELFH18160 must be used.

Q: Do both parts meet RoHS requirements?

A: Yes. The ELFH18160 is RoHS Compliant, and the 1755668 is ROHS3 Compliant. Both designations indicate compliance with lead-free and restricted substance requirements.

Q: What are the packaging differences?

A: The ELFH18160 is supplied in Tray packaging, while the 1755668 is supplied in Bulk packaging. Packaging format may affect inventory management, handling procedures, and cost per unit but does not affect electrical or mechanical performance.

Q: Are the contact tail lengths identical?

A: Contact tail lengths are equivalent but not identical. The ELFH18160 has a 0.155" (3.94mm) tail length, while the 1755668 has a 0.154" (3.90mm) tail length. This 0.01mm difference is within typical manufacturing tolerance and does not affect PCB hole compatibility or solder joint formation.
