ELFH03180 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The ELFH03180 is a 3-position vertical terminal block header manufactured by Amphenol PCD. This component features male pins with 4-side shrouding, 0.197" (5.00mm) pitch spacing, and solder termination for through-hole mounting. The part is Active status and RoHS Compliant, designed for applications requiring 300V UL voltage rating and 15A UL current capacity. Substitute parts are identified when equivalent electrical specifications, mechanical compatibility, and mounting characteristics align with the original component's functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped based on the following critical parameters that determine functional equivalence:

Primary Compatibility Criteria:

• Number of Positions: 3-position configuration
• Header Orientation: Vertical mounting
• Termination Style: Solder
• Mounting Type: Through Hole
• Voltage Rating: 300V UL minimum
• Material Flammability: UL94 V-0
• Contact Finish: Tin plating

Secondary Consideration:

• Pitch spacing tolerance: 0.197" (5.00mm) nominal or 0.200" (5.08mm) nominal represent standard terminal block pitch increments

Part 1753453 (Phoenix Contact) qualifies as a direct substitute for 3-position applications with matching voltage and flammability ratings, though shrouding configuration differs (2-side vs. 4-side).

Parts 1758018, 1758021, and 1758063 represent alternative position configurations within the same COMBICON MSTBV series, suitable for applications where position count flexibility exists.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (1753453): Part 1753453 maintains 3-position configuration, 0.197" (5.00mm) pitch, vertical orientation, solder termination, and 300V UL voltage rating. Both components are Active status with UL94 V-0 flammability compliance. The primary difference is shrouding configuration (2-side vs. 4-side), which affects EMI shielding characteristics but does not prevent functional substitution in applications where 4-side shrouding is not explicitly required.

Alternative Position Configurations (1758018, 1758021, 1758063): These parts are suitable only when application requirements permit position count variation. Part 1758021 provides 3-position equivalence with 0.200" (5.08mm) pitch spacing. Part 1758018 offers 2-position configuration. Part 1758063 provides 7-position configuration. All maintain vertical orientation, solder termination, 300V UL voltage rating, and UL94 V-0 compliance. Current rating is 12A UL across all Phoenix Contact alternatives versus 15A UL for the ELFH03180.

Compliance Considerations: All substitute parts maintain Active product status and RoHS compliance (ROHS3 for Phoenix Contact parts). Moisture Sensitivity Level remains 1 (Unlimited) across all options.

Frequently Asked Questions (FAQ)

Q: Can 1753453 directly replace ELFH03180 in all applications? A: Part 1753453 is electrically and mechanically compatible for 3-position, 5.00mm pitch applications requiring 300V UL and UL94 V-0 compliance. The 2-side shrouding differs from the 4-side shrouding of ELFH03180. Applications requiring specific EMI shielding or mechanical fit constraints must verify shrouding compatibility.

Q: What is the difference between 0.197" (5.00mm) and 0.200" (5.08mm) pitch? A: These represent standard terminal block pitch increments. The 0.03mm difference reflects manufacturing tolerances in the terminal block industry. Parts with different pitch specifications are not mechanically interchangeable on the same PCB footprint.

Q: Why do Phoenix Contact parts have 12A UL current rating versus 15A for ELFH03180? A: Current rating is determined by contact material, contact geometry, and housing design. The 12A UL rating for Phoenix Contact COMBICON MSTBV series reflects the electrical specifications of that product line. Applications requiring 15A capacity must use ELFH03180 or equivalent Amphenol parts.

Q: Are the Phoenix Contact parts suitable for applications requiring 4-side shrouding? A: No. The Phoenix Contact COMBICON MSTBV series features 2-side shrouding. Applications with specific EMI shielding or mechanical protection requirements necessitating 4-side shrouding must use ELFH03180 or equivalent Amphenol shrouded designs.

Q: Can I use 1758021 (3-position, 5.08mm pitch) instead of ELFH03180 (3-position, 5.00mm pitch)? A: No. Pitch spacing determines PCB footprint compatibility. These parts are not interchangeable on the same circuit board layout. Use only when PCB design accommodates 5.08mm pitch spacing.

Q: What is the inventory status for substitute parts? A: 1753453 has 2613 pcs in stock, 1758018 has 14517 pcs, 1758021 has 3718 pcs, and 1758063 has 779 pcs available as new original stock.
