ELFH04190 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH04190 is a 4-position vertical terminal block header manufactured by Amphenol PCD. This component features male pins with 2-side shrouding, a 0.197" (5.00mm) pitch, and solder termination for through-hole mounting. The part is actively produced and stocked with 1,080 units available. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when alternative specifications meet application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following critical parameters:

• Number of Positions: Must be 4
• Header Type: Must be Header with Male Pins, Shrouded (2 Side)
• Termination Style: Must be Solder
• Mounting Type: Must be Through Hole
• Pitch Tolerance: 0.197" (5.00mm) primary; 0.200" (5.08mm) acceptable as minor pitch variant
• Voltage Rating (UL): Minimum 300 V
• Current Rating (UL): Minimum 12 A (ELFH04190 rated 15 A)
• Material Flammability: UL94 V-0 required
• RoHS Compliance: RoHS or ROHS3 compliant

Substitute parts are grouped into two categories:

Group 1 - Exact Pitch Match (5.00mm): Parts 1753479 and 1755260 maintain the original 5.00mm pitch specification.

Group 2 - Minor Pitch Variant (5.08mm): Parts 1758034 and 1955400 feature a 5.08mm pitch, representing a 0.08mm tolerance deviation suitable for applications where minor pitch variation is acceptable within mechanical design constraints.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Exact Pitch Match - 5.00mm)

Parts 1753479 and 1755260 are direct functional equivalents with identical 5.00mm pitch specification. Both are manufactured by Phoenix Contact and maintain UL94 V-0 flammability compliance. Part 1753479 carries ROHS3 compliance and features green housing. Part 1755260 offers black housing with standard RoHS compliance and PBT housing material. Current ratings are reduced to 12 A compared to the ELFH04190's 15 A rating; applications must confirm this reduction is acceptable. Both parts are actively produced and maintain substantial inventory levels.

Secondary Substitutes (Minor Pitch Variant - 5.08mm)

Parts 1758034 and 1955400 feature a 5.08mm pitch, representing a 0.08mm deviation from the original specification. These parts are suitable only for applications where mechanical design tolerances accommodate minor pitch variation. Part 1758034 maintains 12 A current rating with ROHS3 compliance and polyamide housing. Part 1955400 features liquid crystal polymer housing with reduced 10 A current rating and standard RoHS compliance. The 1955400 exhibits a significantly shorter contact tail length (0.102" versus 0.155"), which may affect PCB clearance and solder joint geometry. Selection of 5.08mm pitch variants requires design verification.

Compliance Considerations

All substitute parts maintain UL94 V-0 flammability rating and 300 V UL voltage specification. RoHS and ROHS3 compliance statuses are equivalent for regulatory purposes. Operating temperature data is not provided for substitute parts; applications requiring -40°C to 105°C operation must confirm compatibility through manufacturer documentation.

Frequently Asked Questions (FAQ)

Q: Can I use a 5.08mm pitch part (1758034 or 1955400) as a direct replacement for the ELFH04190?

A: No, not without design verification. The 0.08mm pitch difference may exceed PCB layout tolerances. Mechanical compatibility must be confirmed before substitution. If your design accommodates 5.08mm pitch, these parts are functionally equivalent.

Q: What is the impact of the reduced current rating on substitute parts?

A: Parts 1753479 and 1755260 are rated 12 A versus the ELFH04190's 15 A. Part 1955400 is rated 10 A. If your application requires 15 A per position, these substitutes are not suitable. Verify actual current requirements before selection.

Q: Why does part 1955400 have a shorter contact tail length?

A: The 1955400 contact tail is 0.102" (2.60mm) compared to 0.155" (3.94mm) on the ELFH04190. This shorter tail affects solder joint formation and PCB clearance. Verify PCB hole depth and solder pad design compatibility before use.

Q: Are all substitute parts RoHS compliant?

A: Yes. The ELFH04190 is RoHS Compliant. Substitutes 1753479 and 1758034 are ROHS3 Compliant. Substitute 1755260 and 1955400 are RoHS Compliant. All statuses meet current regulatory requirements.

Q: What is the difference between the housing materials used in substitute parts?

A: ELFH04190 uses Polyamide (PA46) Nylon 4/6. Substitutes use Polyamide (PA) Nylon, Polybutylene Terephthalate (PBT), or Liquid Crystal Polymer (LCP). Material differences affect thermal performance and mechanical properties. Confirm material compatibility with your application environment.

Q: Can I mix ELFH04190 and substitute parts in the same assembly?

A: Mixing parts with different pitches (5.00mm and 5.08mm) in the same assembly is not recommended. If using multiple parts within a single design, maintain consistent pitch specification. Parts with identical pitch (1753479, 1755260 with ELFH04190) may be mixed if current and voltage ratings are acceptable.

Q: What packaging formats are available?

A: ELFH04190 is supplied in Tray packaging. All Phoenix Contact substitutes are supplied in Bulk packaging. Confirm packaging compatibility with your procurement and assembly processes.
