ELFH03160 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The ELFH03160 is a 3-position vertical terminal block header manufactured by Amphenol PCD. This component features male pins with 2-side shrouding, a 5.00mm pitch, and solder termination for through-hole mounting. The part is actively produced and RoHS compliant, designed for applications requiring reliable electrical connections in industrial and commercial equipment. Substitute parts may be required due to inventory constraints, manufacturing discontinuation, or specific application requirements for alternative pitch spacing or position configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH03160 is determined by the following critical parameters: header type (male pins with 2-side shrouding), termination style (solder), mounting type (through hole), and material flammability rating (UL94 V-0). The substitute parts are grouped into two categories based on pitch compatibility:

Category A - Direct Pitch Match (5.00mm): Part 1753453 maintains the identical 5.00mm pitch and 3-position configuration, making it the closest functional equivalent.

Category B - Alternate Pitch (5.08mm): Parts 1758018, 1758021, and 1758063 operate at 5.08mm pitch spacing. These parts are suitable for applications where pitch tolerance permits minor spacing variations. Part 1758018 provides a 2-position alternative, part 1758021 offers 3-position matching, and part 1758063 provides a 7-position option for expanded connectivity requirements.

All substitute parts maintain solder termination, through-hole mounting, vertical orientation, and UL94 V-0 flammability compliance. Voltage ratings across all substitutes meet or exceed the 300V UL specification of the main part.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - Part 1753453: This Phoenix Contact terminal block header maintains identical electrical and mechanical specifications to the ELFH03160, including 3-position configuration and 5.00mm pitch. Both parts are actively produced, RoHS compliant, and rated for 300V UL operation. The contact tail length and insulation height are within 0.001" tolerance. This part is the recommended direct replacement when ELFH03160 availability is constrained.

Secondary Substitutes - Parts 1758018, 1758021, 1758063: These Phoenix Contact components operate at 5.08mm pitch, representing a 0.08mm spacing increase from the original specification. All three maintain UL94 V-0 flammability compliance and 300V UL voltage rating. Part 1758021 provides 3-position functionality matching the ELFH03160 position count. Parts 1758018 and 1758063 offer alternative position configurations (2 and 7 positions respectively) for applications requiring different connectivity requirements. These substitutes are suitable only when PCB layout and connector mating tolerances accommodate the pitch variation.

All substitute parts are actively produced by Phoenix Contact and carry ROHS3 compliance certification, exceeding the RoHS requirements of the original part.

Frequently Asked Questions (FAQ)

Q: Can part 1753453 be used as a direct replacement for ELFH03160? A: Yes. Part 1753453 maintains identical pitch (5.00mm), position count (3), header type (male pins, shrouded), termination style (solder), and mounting configuration (through hole vertical). Both parts meet 300V UL voltage and UL94 V-0 flammability requirements.

Q: What is the difference between the 5.00mm and 5.08mm pitch variants? A: The ELFH03160 and 1753453 operate at 5.00mm (0.197") pitch spacing. Parts 1758018, 1758021, and 1758063 operate at 5.08mm (0.200") pitch spacing. This 0.08mm difference affects PCB hole spacing and connector mating compatibility. Substitution with 5.08mm pitch parts requires verification that PCB layout and mating connectors accommodate the spacing variation.

Q: Are the Phoenix Contact substitutes compatible with existing connectors designed for ELFH03160? A: Part 1753453 is fully compatible due to identical pitch and configuration. Parts 1758018, 1758021, and 1758063 with 5.08mm pitch may not be compatible with connectors designed for the 5.00mm pitch ELFH03160. Connector compatibility must be verified before substitution.

Q: What is the current rating difference between ELFH03160 and the Phoenix Contact substitutes? A: The ELFH03160 is rated for 15A UL current. All Phoenix Contact substitutes (1753453, 1758018, 1758021, 1758063) are rated for 12A UL current. Applications requiring the full 15A capacity should retain the original ELFH03160 specification.

Q: Do all substitute parts meet RoHS compliance? A: Yes. The ELFH03160 is RoHS Compliant. All substitute parts (1753453, 1758018, 1758021, 1758063) are ROHS3 Compliant, which exceeds the original RoHS requirement.

Q: What position configurations are available among the substitutes? A: Part 1753453 provides 3-position matching the ELFH03160. Part 1758018 offers 2-position configuration. Part 1758021 provides 3-position. Part 1758063 provides 7-position. Selection depends on the specific connectivity requirements of the application.
