ELFH20290 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH20290 is a 20-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 15 A at 300 V (UL). The part is currently active in production with 802 units in stock. Alternative equivalent parts are available from Phoenix Contact to support supply chain flexibility and design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH20290 is determined by the following critical parameters:

Core Compatibility Requirements:

• 20-position configuration with 0.200" (5.08mm) pitch spacing
• Vertical through-hole mounting orientation
• Male pin header type with shrouded design
• Solder termination style
• Minimum voltage rating of 300 V (UL)
• UL94 V-0 flammability rating
• Tin contact mating finish

Acceptable Variations:

• Shrouding configuration (2-side or 4-side) may differ while maintaining electrical and mechanical compatibility
• Housing color variations are permitted
• Current ratings may exceed the minimum 15 A requirement
• Voltage ratings may exceed 300 V
• RoHS compliance status may differ (RoHS Compliant or ROHS3 Compliant)

The two Phoenix Contact parts (1755914 and 1758199) meet these substitution criteria. Part 1758199 provides the closest match with identical 2-side shrouding, while part 1755914 offers 4-side shrouding as an alternative configuration.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Phoenix Contact 1758199 (COMBICON MSTBV)

Part 1758199 is the direct functional equivalent with identical 2-side shrouding configuration. Both parts maintain UL94 V-0 flammability compliance and tin contact finish. The contact tail length and insulation height are within 0.001" tolerance. This part is suitable for direct replacement in applications where the ELFH20290 is specified.

Alternative Substitute: Phoenix Contact 1755914 (COMBICON MSTBVA)

Part 1755914 provides 4-side shrouding instead of 2-side, offering enhanced mechanical protection. This configuration is acceptable where board layout and connector mating requirements permit the additional shrouding. Both parts maintain equivalent electrical ratings and compliance certifications.

Compliance Considerations:

All three parts carry UL94 V-0 flammability ratings and tin contact finishes. The ELFH20290 is RoHS Compliant, while both Phoenix Contact substitutes are ROHS3 Compliant. Both substitute parts include REACH Unaffected status. These compliance differences do not restrict substitution in applications requiring either standard.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1758199 be used as a direct replacement for ELFH20290?

A: Yes. Both parts share identical position count (20), pitch (5.08mm), vertical orientation, 2-side shrouding, solder termination, and UL94 V-0 rating. Contact tail length and insulation height are within 0.001" tolerance. The parts are mechanically and electrically compatible.

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

A: The ELFH20290 and Phoenix Contact 1758199 feature 2-side shrouding, protecting the top and bottom of the header. Phoenix Contact 1755914 provides 4-side shrouding, extending protection to all four sides. The 4-side configuration offers additional mechanical protection but requires verification of board layout compatibility.

Q: Are there current rating differences between these parts?

A: The ELFH20290 is rated for 15 A (UL), while both Phoenix Contact substitutes are rated for 12 A (UL). For applications requiring the full 15 A capacity, the ELFH20290 must be used. For applications operating at or below 12 A, both substitutes are acceptable.

Q: Do RoHS compliance differences affect substitution?

A: No. The ELFH20290 is RoHS Compliant, while the Phoenix Contact parts are ROHS3 Compliant. Both standards restrict hazardous substances and are compatible with modern supply chain requirements. Substitution is not restricted by these differences.

Q: What are the dimensional tolerances between these parts?

A: Contact tail length differs by 0.001" (3.94mm vs. 3.90mm), and insulation height differs by 0.003" (12.07mm vs. 12.00mm). These variations are within typical manufacturing tolerances for terminal block headers and do not affect PCB mounting or connector mating.

Q: Can these parts be used interchangeably in the same circuit board design?

A: Yes, provided the application current requirement does not exceed 12 A. Verify that board layout accommodates the shrouding configuration (2-side or 4-side) and that connector mating requirements are met. Contact tail length and insulation height variations are within acceptable tolerances for standard through-hole PCB designs.
