ELFH18190 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH18190 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 936 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 voltage rating specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH18190 is determined by the following critical parameters:

• Position Count & Pitch: Substitute parts must maintain 18 positions with 0.197" (5.00mm) pitch spacing to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Header Orientation & Termination: Vertical orientation with solder termination is required for through-hole mounting compatibility.
• Electrical Ratings: Substitute parts must meet or exceed the UL voltage rating of 300 V. Current ratings of 12 A or higher are acceptable for equivalent functionality.
• Shrouding Configuration: The ELFH18190 features 2-side shrouding. Substitute parts with enhanced shrouding (4-side) provide improved mechanical protection and are functionally compatible.
• Compliance & Material Standards: RoHS compliance and UL94 V-0 flammability rating are required for equivalent substitution in regulated applications.

The Phoenix Contact 1755668 qualifies as a functional equivalent based on matching position count, pitch, orientation, termination style, and compliance certifications, with the distinction of 4-side shrouding providing additional mechanical robustness.

Parameter Comparison

Engineering Selection Recommendations

Both the ELFH18190 and 1755668 maintain Active product status and meet required compliance standards for regulated applications. The ELFH18190 offers a UL current rating of 15 A, providing 3 A additional capacity over the 1755668. The 1755668 features 4-side shrouding compared to the 2-side shrouding of the ELFH18190, offering enhanced mechanical protection and strain relief in applications subject to vibration or mechanical stress. Both parts are RoHS compliant and carry UL94 V-0 flammability certification. Contact tail length and insulation height dimensions are equivalent within manufacturing tolerances. Selection between these parts should be based on current capacity requirements and the degree of mechanical protection needed for the specific application environment.

Frequently Asked Questions (FAQ)

Q: Can the 1755668 directly replace the ELFH18190 in existing designs?

A: Yes, the 1755668 is mechanically and electrically compatible for direct substitution. Both parts share identical position count (18), pitch (5.00mm), orientation (vertical), and termination method (solder). Contact tail length and insulation height are equivalent within standard manufacturing tolerances. The primary difference is the 4-side shrouding on the 1755668 versus 2-side shrouding on the ELFH18190.

Q: What is the significance of the shrouding difference between these parts?

A: The ELFH18190 features 2-side shrouding, while the 1755668 provides 4-side shrouding. Four-side shrouding offers improved mechanical protection, better strain relief, and enhanced protection against accidental contact. Both configurations are functionally equivalent for electrical performance and mating compatibility.

Q: Are there current rating differences between these parts?

A: The ELFH18190 is rated for 15 A (UL), while the 1755668 is rated for 12 A (UL). For applications requiring currents above 12 A, the ELFH18190 is the appropriate selection. For applications operating at or below 12 A, both parts are suitable.

Q: Do both parts meet the same compliance standards?

A: Both parts carry UL94 V-0 flammability certification and are RoHS compliant. The ELFH18190 is RoHS Compliant, while the 1755668 is ROHS3 Compliant. Both meet regulatory requirements for industrial and commercial applications.

Q: What packaging differences exist between these parts?

A: The ELFH18190 is supplied in Tray packaging with 936 units in current inventory. The 1755668 is supplied in Bulk packaging with 953 units in current inventory. Packaging selection may depend on assembly process requirements and inventory management preferences.

Q: Are the mechanical dimensions interchangeable?

A: Contact tail length and insulation height are equivalent within standard manufacturing tolerances. The ELFH18190 has a contact tail length of 0.155" (3.94mm) and insulation height of 0.475" (12.07mm), while the 1755668 has a contact tail length of 0.154" (3.90mm) and insulation height of 0.472" (12.00mm). These minor dimensional variations are within acceptable tolerances for PCB mounting and mating connector alignment.
