OSTHM026080 Equivalent & Substitute Parts

Part Overview

The OSTHM026080 is a 2-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for vertical PCB mounting with 0.400" (10.16mm) pitch spacing. This component features screwless push-in spring termination and supports wire gauges from 12-28 AWG at 8A/250V ratings. The part is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs.

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM026080 is determined by strict equivalence across the following critical parameters:

Electrical Performance: Current (8A), voltage (250V), and wire gauge acceptance (12-28 AWG) must match or exceed the original specification
Physical Compatibility: Pitch spacing (10.16mm), position count (2), and through-hole mounting configuration must be identical
Termination Method: Screwless push-in spring termination is required for direct substitution
Environmental Compliance: RoHS3 compliance and MSL rating (1 - Unlimited) must be maintained
Mechanical Interface: Vertical board orientation and thermoplastic housing material ensure PCB layout compatibility

The substitute part HM0260800000G by Amphenol Anytek meets all these criteria while offering improved product status (Active vs. Obsolete) and enhanced operating temperature range.

Engineering Selection Recommendations

The HM0260800000G from Amphenol Anytek is a direct functional equivalent to the obsolete OSTHM026080. Both components maintain identical electrical ratings, mechanical dimensions, and termination characteristics. The substitute part offers the following advantages:

Active Product Status: HM0260800000G is currently in active production, ensuring long-term availability and supply chain stability
Enhanced Temperature Range: Operating range of -40°C to 115°C exceeds the original -30°C to 105°C specification, providing broader application flexibility
Improved Contact Plating: Tin-plated brass contacts provide enhanced corrosion resistance compared to unplated brass
Regulatory Compliance: Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1)

For new designs or production transitions, the HM0260800000G is the recommended selection. For legacy system repairs requiring exact form-fit-function compatibility, the HM0260800000G provides seamless substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can HM0260800000G be used as a direct replacement for OSTHM026080 in existing PCB designs?

A: Yes. Both components share identical pitch spacing (10.16mm), position count (2), through-hole mounting configuration, and electrical ratings (8A/250V). No PCB layout modifications are required.

Q: What is the significance of the tin plating on the HM0260800000G contacts?

A: Tin plating provides enhanced corrosion resistance and improved contact reliability in humid or corrosive environments compared to bare brass. This is a material enhancement that does not affect electrical performance or mechanical compatibility.

Q: Are there any temperature-related limitations when substituting the HM0260800000G?

A: No. The HM0260800000G operates across a wider temperature range (-40°C to 115°C) than the original part (-30°C to 105°C). Applications within the original temperature specification are fully supported.

Q: Do both parts accept the same wire gauge range?

A: Yes. Both OSTHM026080 and HM0260800000G accept 12-28 AWG wire gauges with identical push-in spring termination.

Q: What is the packaging difference between these parts?

A: OSTHM026080 packaging is not specified in the original documentation. HM0260800000G is supplied in bulk packaging. Confirm packaging requirements with your procurement specification.

Q: Are both parts RoHS compliant?

A: Yes. Both OSTHM026080 and HM0260800000G are ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity level).
