ELFH20190 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH20190 is a 20-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 5.00mm 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 786 units in stock. Equivalent and substitute parts are identified for applications requiring alternative sourcing, inventory management, or specific compliance certifications.

Substitute Part Grouping Explanation

Substitute parts for the ELFH20190 are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Number of positions: 20 (exact match required)
• Termination style: Solder (exact match required)
• Mounting type: Through hole vertical (exact match required)
• Pitch tolerance: 5.00mm to 5.08mm (minor pitch variation acceptable within mechanical tolerance)
• Shrouding configuration: 2-side or 4-side (both provide equivalent electrical isolation)
• Voltage rating: Minimum 300V UL (equal or higher acceptable)
• Current rating: Minimum 12A (equal or higher acceptable)
• Flammability rating: UL94 V-0 (equivalent or superior)
• RoHS compliance: Compliant or ROHS3 Compliant (both acceptable)

The two identified substitutes (Phoenix Contact 1755914 and 1758199) meet these criteria with minor pitch variations (5.08mm vs 5.00mm) that remain within standard PCB design tolerances for terminal block headers.

Parameter Comparison

Engineering Selection Recommendations

ELFH20190 (Amphenol PCD) remains the primary specification for applications requiring the exact 5.00mm pitch and 15A UL current rating. This part is active in production with adequate inventory (786 units).

1758199 (Phoenix Contact COMBICON MSTBV) is the preferred substitute when Phoenix Contact sourcing is required or when inventory constraints affect ELFH20190 availability. This part matches the 2-side shrouding configuration of the main part and meets all UL voltage and current requirements. The 5.08mm pitch represents a 0.08mm variation that remains within standard PCB design tolerances for terminal block applications. RoHS3 compliance provides equivalent environmental compliance to RoHS Compliant status.

1755914 (Phoenix Contact COMBICON MSTBVA) is an alternative substitute with 4-side shrouding, providing enhanced electrical isolation compared to the 2-side configuration. The 5.08mm pitch and electrical ratings remain equivalent to the main part. This option is suitable for applications where increased shrouding is beneficial.

Both Phoenix Contact substitutes carry ROHS3 Compliant certification and meet the UL94 V-0 flammability requirement. Selection between substitutes should be based on shrouding preference (2-side vs 4-side) and specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1758199 be used as a direct replacement for ELFH20190?

A: Yes, within standard PCB design tolerances. The 5.08mm pitch of the 1758199 differs from the ELFH20190 by 0.08mm. For most applications, this variation is accommodated by standard PCB hole tolerances and terminal block mounting practices. Verify PCB layout compatibility before implementation.

Q: What is the difference between the 1755914 and 1758199 substitutes?

A: Both parts share identical electrical ratings and pitch specifications. The primary difference is shrouding configuration: the 1755914 features 4-side shrouding, while the 1758199 features 2-side shrouding matching the ELFH20190. Select based on application requirements for electrical isolation and mechanical fit.

Q: Are there current rating differences between the main part and substitutes?

A: The ELFH20190 is rated for 15A at UL, while both Phoenix Contact substitutes are rated for 12A at UL. For applications requiring the full 15A capacity, the ELFH20190 is the appropriate selection. For applications operating at or below 12A, the substitutes are functionally equivalent.

Q: Do the substitutes meet the same compliance standards?

A: Both Phoenix Contact substitutes are ROHS3 Compliant and UL94 V-0 rated, meeting or exceeding the compliance profile of the ELFH20190. Both carry EAR99 ECCN classification and 8536.69.4040 HTSUS code, matching the main part.

Q: What packaging differences exist between these parts?

A: The ELFH20190 is supplied in Tray packaging, while both Phoenix Contact substitutes are supplied in Bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Is the operating temperature range specified for the substitutes?

A: Operating temperature data is not provided for the Phoenix Contact substitutes in the available specifications. The ELFH20190 specifies -40°C to 105°C operation. Consult Phoenix Contact technical documentation for complete thermal specifications if operating temperature range is a critical design parameter.
