ELFH09280 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH09280 is a 9-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 0.200" (5.08mm) pitch spacing. This shrouded male pin header operates at 300V UL and 15A UL current rating, suitable for industrial control and power distribution applications. The component is active in production with full RoHS compliance and MSL Level 1 rating. Substitute parts are identified to address inventory availability, regional sourcing requirements, or specific application constraints while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH09280 is determined by the following critical parameters:

Mandatory Match Criteria:

• Number of positions: 9 (exact match required)
• Header orientation: Vertical (exact match required)
• Termination style: Solder (exact match required)
• Mounting type: Through hole (exact match required)

Compatible Variance Criteria:

• Pitch tolerance: 0.197" (5.00mm) to 0.200" (5.08mm) represents a 0.03mm variance, acceptable within standard PCB manufacturing tolerances for terminal block applications
• Voltage rating: Substitute must meet or exceed 300V UL minimum
• Current rating: Substitute must meet or exceed 15A UL minimum
• Shrouding configuration: Both 2-side and 4-side shrouded designs provide equivalent electrical isolation and mechanical protection for vertical through-hole applications
• Contact tail length: 0.154" (3.90mm) to 0.155" (3.94mm) variance is within acceptable solder joint formation parameters
• Insulation height: 0.472" (12.00mm) to 0.475" (12.07mm) variance does not affect functional performance

The substitute part 1753576 (Phoenix Contact COMBICON MSTBV series) meets all mandatory criteria and operates within acceptable variance parameters for direct substitution.

Engineering Selection Recommendations

ELFH09280 (Primary Selection): Use when 15A UL current rating is required and 4-side shrouding is specified for the application. This component is active in production with 682 units in stock, ensuring supply continuity. RoHS compliance and UL94 V-0 flammability rating meet standard industrial control requirements.

1753576 (Substitute Selection): Use when Phoenix Contact COMBICON MSTBV series integration is preferred or when regional sourcing from Phoenix Contact is advantageous. This substitute meets the 300V UL voltage requirement and provides 12A UL current capacity, suitable for applications not requiring the full 15A rating of the primary part. The 2-side shrouding provides equivalent electrical isolation for vertical through-hole mounting. Both components carry active product status, RoHS compliance, and UL94 V-0 certification. The 0.03mm pitch variance and dimensional tolerances on contact tail length and insulation height fall within acceptable PCB assembly parameters.

Selection Constraint: The substitute part 1753576 is rated at 12A UL current, which is lower than the primary part's 15A UL rating. Applications requiring sustained 15A operation must use ELFH09280.

Frequently Asked Questions (FAQ)

Q: Can 1753576 be used as a direct replacement for ELFH09280 in all applications?

A: The 1753576 is functionally compatible for applications operating at 12A UL or below. Applications requiring the full 15A UL capacity of the ELFH09280 must use the primary part. Both components meet the 300V UL voltage requirement and share identical 9-position vertical through-hole configuration.

Q: What is the significance of the pitch difference between 5.08mm and 5.00mm?

A: The 0.03mm variance is within standard PCB manufacturing tolerances for terminal block footprints. Both parts are compatible with standard 5.08mm pitch PCB hole patterns used in industrial control applications. This tolerance is established in IEC 61076 connector standards.

Q: Does the shrouding difference (4-side vs. 2-side) affect substitution compatibility?

A: Both 4-side and 2-side shrouding configurations provide equivalent electrical isolation and mechanical protection for vertical through-hole terminal block applications. The shrouding difference does not affect electrical performance or PCB mounting compatibility. Selection between configurations is based on application-specific mechanical or aesthetic requirements.

Q: Are there any compliance differences between the two parts?

A: Both components are RoHS compliant (ELFH09280 is RoHS Compliant; 1753576 is ROHS3 Compliant), carry UL94 V-0 flammability ratings, and maintain MSL Level 1 moisture sensitivity. Both are active products suitable for current production designs.

Q: What is the impact of the color difference (black vs. green)?

A: Color is a visual identifier only and does not affect electrical or mechanical function. Selection is based on application requirements or internal documentation standards.

Q: Can the contact tail length and insulation height tolerances affect PCB assembly?

A: The 0.01mm variance in contact tail length (0.155" vs. 0.154") and 0.03mm variance in insulation height (0.475" vs. 0.472") are within standard solder joint formation parameters and PCB assembly tolerances. These dimensions do not affect functional compatibility.
