ELFH03260 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH03260 is a 3-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 5.08mm 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 performance, mechanical compatibility, and regulatory compliance can be maintained across alternative manufacturers and product lines.

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH03260 is determined by strict equivalence across the following parameters:

Electrical Compatibility: Current rating (15 A UL), voltage rating (300 V UL), and contact material properties must support identical circuit requirements
Mechanical Compatibility: 3-position configuration, 5.08mm pitch, vertical orientation, male pin shrouded design, and through-hole mounting must be maintained
Termination Method: Solder termination is required; no alternative attachment methods are acceptable
Regulatory Compliance: UL94 V-0 flammability rating and RoHS compliance status must be met or exceeded
Environmental Performance: Operating temperature range and moisture sensitivity level must support the application environment

The substitute part 282825-3 (TE Connectivity AMP Connectors, Buchanan series) meets all mandatory electrical and mechanical parameters while maintaining regulatory compliance.

Engineering Selection Recommendations

The ELFH03260 and 282825-3 are electrically and mechanically interchangeable for applications requiring 3-position, 5.08mm pitch vertical terminal block headers with solder termination. Both components maintain UL94 V-0 flammability compliance and RoHS certification status, satisfying regulatory requirements for industrial and commercial applications.

The 282825-3 substitute provides an extended operating temperature range (-40°C to 110°C versus -40°C to 105°C), offering additional thermal margin in high-temperature environments. Housing material differs between the two parts (Polybutylene Terephthalate in the ELFH03260 versus Polyamide PA66 in the 282825-3), and contact material composition varies (Brass versus Copper Alloy), though both maintain equivalent electrical performance at the specified current and voltage ratings.

Selection between these parts should be based on availability, lead time, packaging requirements (Tray for ELFH03260 versus Bulk for 282825-3), and application-specific environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the 282825-3 be used as a direct replacement for the ELFH03260 in existing PCB designs?

A: Yes. Both components share identical electrical ratings (15 A, 300 V), mechanical configuration (3-position, 5.08mm pitch, vertical orientation), and termination method (solder). PCB footprints and mounting hole patterns are compatible.

Q: What are the differences in housing material between these parts?

A: The ELFH03260 uses Polybutylene Terephthalate (PBT), while the 282825-3 uses Polyamide (PA66). Both materials meet UL94 V-0 flammability requirements and provide equivalent electrical insulation properties for this application.

Q: Are there differences in contact tail length or insulation height?

A: Minor dimensional variations exist. The ELFH03260 has a contact tail length of 0.155" (3.94mm) and insulation height of 0.475" (12.07mm), while the 282825-3 has a contact tail length of 0.138" (4.60mm) and insulation height of 0.472" (12.00mm). These variations are within acceptable tolerances for standard PCB through-hole mounting.

Q: What is the difference in packaging between these parts?

A: The ELFH03260 is supplied in Tray packaging, while the 282825-3 is supplied in Bulk packaging. Packaging selection depends on assembly process requirements and inventory management practices.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both components are RoHS compliant and carry UL94 V-0 flammability ratings. The 282825-3 carries ROHS3 certification, which represents an updated compliance standard. Both are suitable for applications requiring RoHS compliance.

Q: What is the operating temperature difference between these parts?

A: The ELFH03260 operates from -40°C to 105°C, while the 282825-3 operates from -40°C to 110°C. The 282825-3 provides a 5°C higher upper temperature limit, offering additional thermal margin for high-temperature applications.
