ELFH12120 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH12120 is a 12-position terminal block header manufactured by Amphenol PCD, designed for right-angle through-hole mounting with 5mm pitch spacing. This component is actively produced and stocked, serving as a connector interface for PCB-to-wire applications requiring 15A current capacity at 300V. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and mounting characteristics align with the original design requirements, enabling component interchangeability in production and field applications.

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH12120 is determined by strict alignment of the following critical parameters:

Position Count & Pitch: 12 positions at 0.197" (5.00mm) spacing
Connector Type & Orientation: Header with male pins, shrouded on 2 sides, 90° right-angle configuration
Electrical Ratings: Minimum 15A current capacity and 300V voltage rating
Mounting Method: Through-hole solder termination on PCB
Environmental Compliance: UL94 V-0 flammability rating and RoHS compliance

The substitute part 1-282812-2 (TE Connectivity AMP Connectors, Buchanan series) meets all substitution criteria. Both components share identical position count, pitch, orientation, termination style, and electrical ratings. Mechanical variations exist in contact tail length and insulation height, which do not affect functional interchangeability in standard PCB mounting applications.

Engineering Selection Recommendations

Both the ELFH12120 and 1-282812-2 are active products with current manufacturing status and full regulatory compliance. Selection between these components should be based on:

ELFH12120 (Amphenol PCD): Select when PBT housing material is specified, when black color coding is required for circuit identification, or when the narrower operating temperature range (-40°C to 105°C) is acceptable for the application.

1-282812-2 (TE Connectivity): Select when PA66/Nylon 6/6 housing material is preferred, when green color coding aligns with assembly standards, when the extended operating temperature range (-40°C to 110°C) provides margin for thermal environments, or when side stacking capability is required. ROHS3 compliance provides alignment with current regulatory frameworks.

Both components meet UL94 V-0 flammability requirements and carry RoHS compliance certifications. Mechanical differences in contact tail length and insulation height are within standard PCB footprint tolerances for 5mm pitch terminal block applications.

Frequently Asked Questions (FAQ)

Q: Can 1-282812-2 be used as a direct replacement for ELFH12120 in existing PCB designs?

A: Yes, for standard through-hole solder mounting applications. Both components share identical position count (12), pitch spacing (5.00mm), orientation (90° right angle), and electrical ratings (15A, 300V). Verify that PCB footprint tolerances accommodate the minor differences in contact tail length (0.155" vs 0.138") and insulation height (0.319" vs 0.329"). Color difference (black vs green) is cosmetic and does not affect electrical function.

Q: What are the key differences between these two parts?

A: Primary differences are housing material (PBT vs PA66/Nylon 6/6), contact material (Brass vs Copper Alloy), operating temperature range (105°C vs 110°C maximum), and color (black vs green). Electrical and mechanical compatibility remains unchanged. The 1-282812-2 includes side stacking capability, which may be advantageous in modular connector applications.

Q: Are both parts currently available?

A: Yes. ELFH12120 inventory: 1,109 pieces. 1-282812-2 inventory: 846 pieces. Both are listed as active products with new original stock.

Q: Which part should be selected for high-temperature applications?

A: The 1-282812-2 supports operation to 110°C, compared to 105°C for the ELFH12120. For applications approaching or exceeding 105°C, the TE Connectivity part provides additional thermal margin.

Q: Do packaging differences affect component selection?

A: ELFH12120 is supplied in trays; 1-282812-2 is supplied in bulk. Packaging selection depends on production volume and handling requirements. Electrical and mechanical specifications remain independent of packaging format.
