Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH04180 is determined by the following critical parameters:

• Position Count & Pitch: All substitute parts maintain 4 positions with either 5.00mm (0.197") or 5.08mm (0.200") pitch, ensuring mechanical and electrical compatibility with mating connectors.
• Header Type & Orientation: All substitutes are vertical male pin headers with shrouding, maintaining the same form factor and mounting orientation.
• Termination & Mounting: All parts use solder termination and through-hole mounting, preserving PCB assembly compatibility.
• Electrical Ratings: Substitute parts meet or exceed the UL voltage requirement of 300V. Current ratings vary (10A to 15A per position), requiring verification against circuit requirements.
• Compliance & Temperature: All substitutes maintain UL94 V-0 flammability rating and operate within the -40°C to 105°C temperature range, ensuring regulatory and thermal compatibility.
• Shrouding Configuration: The ELFH04180 features 4-side shrouding; Phoenix Contact substitutes provide 2-side shrouding, which is functionally equivalent for connector mating but offers reduced mechanical protection.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (5.00mm Pitch):

Parts 1753479 and 1755260 maintain the same 5.00mm pitch as the ELFH04180, ensuring direct mechanical compatibility with existing mating connectors. Both are Phoenix Contact COMBICON MSTBV series components with active product status and full RoHS compliance. Part 1753479 supports 12A at UL ratings with green housing and polyamide construction. Part 1755260 also supports 12A with black housing and PBT material, offering improved chemical resistance. Both feature 2-side shrouding compared to the ELFH04180's 4-side design, reducing mechanical protection but maintaining electrical functionality.

Pitch-Compatible Alternatives (5.08mm Pitch):

Parts 1758034 and 1955400 operate at 5.08mm pitch, which is mechanically and electrically compatible with standard 5.08mm pitch mating connectors but not interchangeable with 5.00mm pitch systems. Part 1758034 is a Phoenix Contact COMBICON MSTBV component rated for 12A with polyamide housing and ROHS3 compliance. Part 1955400 is a Phoenix Contact COMBICON CCV series component rated for 10A with liquid crystal polymer housing and RoHS compliance. Both maintain UL94 V-0 flammability rating and 300V UL voltage specification.

Current Rating Considerations:

The ELFH04180 is rated for 15A under UL specifications. Substitutes 1753479, 1755260, and 1758034 are rated for 12A, while 1955400 is rated for 10A. Selection must account for circuit current requirements. If the application requires the full 15A capacity, the ELFH04180 is the only option among these parts.

Compliance & Temperature:

All parts maintain UL94 V-0 flammability rating and operate within the -40°C to 105°C temperature range, ensuring regulatory compliance and thermal compatibility across standard industrial applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute the ELFH04180 with a 5.08mm pitch part?

A: Parts 1758034 and 1955400 operate at 5.08mm pitch. Substitution is possible only if your mating connector is designed for 5.08mm pitch. Direct substitution into a 5.00mm pitch system will result in misalignment and connection failure.

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

A: The ELFH04180 features 4-side shrouding, providing mechanical protection on all sides. Phoenix Contact substitutes feature 2-side shrouding, protecting only two sides. Both configurations maintain electrical functionality and connector mating compatibility. 2-side shrouding reduces material and cost while providing adequate protection for most applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. The ELFH04180 is RoHS Compliant. Substitutes 1753479 and 1758034 are ROHS3 Compliant, while 1755260 and 1955400 are RoHS Compliant. All meet current RoHS requirements.

Q: Which substitute should I use if my circuit requires 15A?

A: None of the listed substitutes support 15A. The ELFH04180 is the only option rated for 15A under UL specifications. If 15A capacity is required, the ELFH04180 must be used.

Q: Can I use a substitute with lower current rating if my circuit draws less current?

A: Yes. If your circuit draws 10A or less, part 1955400 is suitable. If your circuit draws 12A or less, parts 1753479, 1755260, or 1758034 are suitable. Current rating selection must match or exceed actual circuit requirements.

Q: What is the difference in housing material between substitutes?

A: The ELFH04180 uses Polyamide (PA46) Nylon 4/6. Substitutes use Polyamide (PA) Nylon, Polybutylene Terephthalate (PBT), or Liquid Crystal Polymer (LCP). PBT and LCP offer improved chemical and thermal resistance compared to polyamide. Material selection depends on environmental exposure and chemical compatibility requirements.

Q: Are all parts suitable for through-hole PCB assembly?

A: Yes. All parts use solder termination and through-hole mounting, maintaining compatibility with standard PCB assembly processes.
