OSTHM078080 Equivalent & Substitute Parts

Part Overview

The OSTHM078080 is a 7-position wire-to-board terminal block manufactured by On-Shore Technology, designed for vertical PCB mounting with 10mm pitch spacing. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The terminal block accommodates wire gauges from 12 to 28 AWG with a rated current capacity of 8A at 250V, utilizing screwless push-in spring termination for reliable wire connections.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM078080 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Current rating (8A), voltage rating (250V), and wire gauge compatibility (12-28 AWG) must be identical
• Physical Configuration: 7 positions per level, 10mm pitch spacing, and vertical-with-board mating orientation must match exactly
• Termination Method: Screwless push-in spring termination is required
• Mounting: Through-hole PCB mounting only
• Material Compliance: ROHS3 compliance and thermoplastic housing construction

The substitute part HM0780800000G, manufactured by Amphenol Anytek, meets all these criteria while offering active product status and improved operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The HM0780800000G from Amphenol Anytek is a direct functional equivalent to the obsolete OSTHM078080. Both components maintain identical electrical ratings, physical dimensions, and termination characteristics. The substitute part offers the advantage of active product status, ensuring continued availability and supply chain reliability. Both parts satisfy ROHS3 compliance and REACH regulatory requirements. The HM0780800000G provides an extended operating temperature range (-40°C to 115°C versus -30°C to 105°C), which may provide additional thermal margin in demanding applications. Contact material plating differences (tin-plated brass versus unplated brass) do not affect functional compatibility for standard wire-to-board connections.

Frequently Asked Questions (FAQ)

Q: Can HM0780800000G be used as a direct replacement for OSTHM078080?

A: Yes. Both components share identical electrical ratings (8A, 250V), physical configuration (7 positions, 10mm pitch), mounting method (through-hole), and termination technology (screwless push-in spring). PCB footprints are compatible.

Q: What is the primary advantage of switching to HM0780800000G?

A: The HM0780800000G maintains active product status, ensuring long-term availability and supply continuity. The OSTHM078080 is obsolete and subject to inventory depletion.

Q: Are there differences in wire gauge compatibility?

A: No. Both parts accept 12-28 AWG wire gauges identically.

Q: Does the tin plating on HM0780800000G contacts affect performance?

A: No. Tin plating on brass contacts improves corrosion resistance and does not alter electrical or mechanical compatibility with the push-in spring termination system.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both OSTHM078080 and HM0780800000G are ROHS3 compliant and REACH unaffected.

Q: What is the temperature operating range difference?

A: OSTHM078080 operates from -30°C to 105°C. HM0780800000G operates from -40°C to 115°C, providing extended thermal capability.
