ELFH18260 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH18260 is an 18-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 0.200" (5.08mm) pitch spacing. This component features male pins with 2-side shrouding and is rated for 15A at 300V (UL). The part is currently active in production with 1043 units in stock. Alternative models may be required due to inventory constraints, packaging preferences, or specific application requirements for different shrouding configurations or pitch tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELFH18260 is evaluated based on the following critical parameters that must align for functional equivalence:

• Position Count: 18 positions (fixed requirement)
• Pitch Tolerance: 0.200" (5.08mm) nominal, with 0.197" (5.00mm) acceptable within mechanical tolerance
• Orientation: Vertical through-hole mounting
• Pin Configuration: Male pins with shrouding
• Termination: Solder connection
• Electrical Ratings: Minimum 300V voltage rating; current rating of 12A or higher
• Compliance: RoHS compliant; UL94 V-0 flammability rating

The Phoenix Contact 1755668 qualifies as a substitute based on these parameters. While it features 4-side shrouding (versus 2-side on the ELFH18260) and operates at 12A (versus 15A), both are within acceptable substitution criteria for applications not requiring the full 15A capacity. The pitch variance of 0.003" (0.08mm) is within standard mechanical tolerance for terminal block headers.

Parameter Comparison

Engineering Selection Recommendations

Both the ELFH18260 and 1755668 are active production components with full RoHS compliance and UL94 V-0 flammability certification, meeting standard industrial safety requirements.

The ELFH18260 is the primary selection for applications requiring the full 15A current capacity. The 2-side shrouding provides standard EMI protection suitable for general industrial terminal block applications.

The Phoenix Contact 1755668 serves as a functional substitute for applications with current requirements of 12A or less. The 4-side shrouding offers enhanced EMI shielding compared to the 2-side design. The pitch difference of 0.003" (0.08mm) is within standard mechanical tolerance and does not affect PCB footprint compatibility for standard terminal block spacing. Both parts maintain identical 300V voltage ratings and operating temperature ranges.

Selection between these parts should be based on current capacity requirements, shrouding preference, and packaging availability rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1755668 be used in place of the ELFH18260 in all applications?

A: The 1755668 is suitable for applications where the current requirement does not exceed 12A. If your circuit requires the full 15A capacity of the ELFH18260, the substitute is not appropriate. Both parts share identical voltage ratings (300V UL) and temperature operating ranges (-40°C to 105°C).

Q: What is the significance of the pitch difference between 0.200" and 0.197"?

A: The 0.003" (0.08mm) difference falls within standard mechanical tolerance for terminal block headers and does not affect PCB footprint compatibility. Both parts are designed for standard 5mm-class terminal block spacing and will function identically on equivalent PCB layouts.

Q: How do the shrouding configurations differ?

A: The ELFH18260 features 2-side shrouding, while the 1755668 provides 4-side shrouding. Both configurations meet UL94 V-0 flammability requirements. The 4-side design offers additional EMI shielding but does not affect electrical performance or current/voltage ratings.

Q: Are both parts RoHS compliant?

A: Yes. The ELFH18260 is RoHS Compliant, and the 1755668 is ROHS3 Compliant. Both meet current RoHS requirements for industrial applications.

Q: What is the difference in contact tail length between these parts?

A: The ELFH18260 has a contact tail length of 0.155" (3.94mm), while the 1755668 measures 0.154" (3.90mm). This 0.001" (0.04mm) difference is negligible for solder joint formation and does not affect assembly or performance.

Q: Can I mix these parts in the same assembly?

A: Yes, both parts can be used in the same assembly provided that each position meets the current requirements of its connected circuit. The mechanical and electrical compatibility allows for mixed deployment without performance degradation.
