ELFH12140 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH12140 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 classified as an active product and serves as a connector interface for PCB-to-wire termination applications requiring solder attachment. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and functional specifications align with the original component's design parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH12140 is determined by strict alignment of the following parameters:

Electrical Compatibility: Current rating (15 A UL), voltage rating (300 V UL), and contact material conductivity
Mechanical Compatibility: 12 positions, 5mm pitch, 90° right-angle orientation, through-hole mounting, male pin configuration with 2-side shrouding
Termination Method: Solder attachment capability
Environmental Compliance: UL94 V-0 flammability rating, RoHS compliance status, and operating temperature range capability

The substitute part 1-282812-2 (TE Connectivity AMP Connectors, Buchanan series) meets all mandatory electrical and mechanical parameters for direct substitution.

Engineering Selection Recommendations

Both the ELFH12140 and 1-282812-2 are active products with equivalent electrical and mechanical specifications. Selection between these components should be based on:

Product Availability: The ELFH12140 is available in tray packaging (791 pcs in stock), while 1-282812-2 is supplied in bulk packaging (846 pcs in stock). Packaging format may influence procurement and handling procedures.

Compliance Status: The ELFH12140 carries RoHS Compliant certification. The 1-282812-2 carries ROHS3 Compliant certification, representing a more recent compliance standard. Both meet UL94 V-0 flammability requirements and EAR99 export classification.

Operating Temperature: The ELFH12140 operates within -40°C to 105°C, while 1-282812-2 extends to -40°C to 110°C. For applications requiring operation above 105°C, the TE Connectivity part provides additional thermal margin.

Housing Material Composition: ELFH12140 uses Polyamide (PA46), Nylon 4/6, while 1-282812-2 uses Polyamide (PA66), Nylon 6/6. Both materials meet UL94 V-0 requirements.

Frequently Asked Questions (FAQ)

Q: Can 1-282812-2 be used as a direct replacement for ELFH12140 in existing designs?

A: Yes. Both components share identical electrical ratings (15 A, 300 V), mechanical configuration (12 positions, 5mm pitch, 90° right-angle), and termination method (solder). PCB footprints and wire termination procedures remain compatible.

Q: What are the differences in contact tail length between these parts?

A: The ELFH12140 has a contact tail length of 0.155" (3.94mm), while 1-282812-2 has 0.138" (4.60mm). This difference may affect solder joint depth and PCB trace routing in designs with tight spacing constraints.

Q: Are there differences in insulation height that affect PCB layout?

A: Yes. The ELFH12140 has an insulation height of 0.319" (8.10mm), while 1-282812-2 measures 0.329" (8.36mm). This 0.01" difference is minimal but should be verified in designs with height-constrained applications.

Q: Does the operating temperature difference impact component selection?

A: The ELFH12140 operates to 105°C, while 1-282812-2 operates to 110°C. For applications operating below 105°C, both parts are equivalent. For applications requiring operation between 105°C and 110°C, only 1-282812-2 is suitable.

Q: What is the significance of the "Side Stacking" feature listed for 1-282812-2?

A: Side stacking capability indicates that 1-282812-2 can be mounted adjacent to other connectors in a side-by-side configuration. This feature does not affect direct substitution compatibility but may provide design flexibility for multi-connector applications.

Q: Are both parts RoHS compliant?

A: Yes. The ELFH12140 is RoHS Compliant, and 1-282812-2 is ROHS3 Compliant. Both meet regulatory requirements for hazardous substance restrictions.
