ELFH19260 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH19260 is a 19-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 701 units in stock.

Terminal block headers of this type are essential in industrial control systems, power distribution panels, and modular electronic assemblies where reliable wire-to-board connections are required. Equivalent and substitute parts may be necessary due to supply chain constraints, design revisions, or specific application requirements that allow for minor parameter variations within acceptable engineering tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for terminal block headers is determined by the following critical parameters:

• Position Count: Must match exactly (19 positions required)
• Pitch Spacing: Must be within 0.003" (0.076mm) tolerance of 0.200" (5.08mm) to ensure PCB footprint compatibility
• Header Orientation: Must be vertical through-hole
• Termination Style: Must be solder-compatible
• Voltage and Current Ratings: Must meet or exceed UL ratings (300V, 15A minimum)
• Shrouding Configuration: 2-side or 4-side shrouding acceptable for mechanical compatibility
• Flammability Rating: Must maintain UL94 V-0 or equivalent
• RoHS Compliance: Must be RoHS3 or RoHS Compliant

The substitute part 1755671 (Phoenix Contact COMBICON MSTBVA series) meets these criteria with a pitch of 0.197" (5.00mm), which falls within acceptable tolerance for PCB mounting, and maintains equivalent electrical ratings and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (ELFH19260): Recommended for applications requiring the full 15A UL current rating. Active production status ensures long-term availability. RoHS compliance and UL94 V-0 flammability rating meet standard industrial requirements.

Substitute Part (1755671): Acceptable for applications where the 12A UL current rating is sufficient. The Phoenix Contact COMBICON MSTBVA series offers ROHS3 compliance, representing the current RoHS standard. The 4-side shrouding provides enhanced mechanical protection compared to the 2-side shrouding of the primary part. Pitch tolerance of 0.197" (5.00mm) is within acceptable PCB footprint variance. Contact tail and insulation height dimensions are functionally equivalent.

Selection Criteria:

• If application current requirement exceeds 12A, use ELFH19260
• If application current requirement is 12A or less, either part is acceptable
• If enhanced mechanical shrouding is beneficial, 1755671 is preferred
• Both parts meet identical voltage, temperature, and compliance requirements

Frequently Asked Questions (FAQ)

Q: Can the 1755671 substitute for ELFH19260 in all applications?

A: The 1755671 is suitable for applications where the UL current rating of 12A meets or exceeds the circuit requirement. If your application requires more than 12A at 300V, the ELFH19260 must be used. Both parts are electrically and mechanically compatible for 19-position vertical through-hole mounting.

Q: What is the significance of the pitch difference (5.08mm vs. 5.00mm)?

A: The 0.08mm difference represents a 1.6% variance and falls within standard PCB manufacturing tolerances. Both parts will mount correctly on PCBs designed for 0.200" (5.08mm) pitch terminal block headers. The substitute part's slightly tighter pitch does not create compatibility issues.

Q: Why does the substitute have 4-side shrouding instead of 2-side?

A: The 4-side shrouding on the 1755671 provides additional mechanical protection and insulation coverage. This is a design enhancement that does not affect electrical performance or PCB compatibility. The 2-side shrouding of the ELFH19260 is functionally adequate for standard applications.

Q: Are both parts RoHS compliant?

A: Yes. The ELFH19260 is RoHS Compliant, and the 1755671 is ROHS3 Compliant. ROHS3 represents the current RoHS standard and includes additional restricted substances. Both parts meet RoHS requirements for industrial applications.

Q: What is the difference in packaging between these parts?

A: The ELFH19260 is supplied in Tray packaging (701 units in stock), while the 1755671 is supplied in Bulk packaging (1150 units in stock). Packaging format does not affect component performance or compatibility.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes, provided your application current requirement does not exceed 12A. The mechanical dimensions, pitch spacing, and electrical ratings are compatible. Both parts use identical solder termination and through-hole mounting.

Q: What are the operating temperature ranges?

A: The ELFH19260 operates from -40°C to 105°C. The operating temperature range for the 1755671 is not specified in the provided data. For applications requiring confirmed temperature specifications, verify with the Phoenix Contact datasheet.
