OSTHM059080 Equivalent & Substitute Parts

Part Overview

The OSTHM059080 is a 5-position wire-to-board terminal block manufactured by On-Shore Technology, designed for vertical PCB mounting with 7.5mm pitch spacing. This component features screwless push-in spring termination and supports wire gauges from 12 to 28 AWG at 8A/250V ratings. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM059080 is determined by strict equivalence across the following critical parameters:

Position count and pitch: 5 positions at 0.295" (7.50mm) spacing
Electrical ratings: 8A current and 250V voltage minimum
Wire termination method: Screwless push-in spring mechanism
Mounting configuration: Through-hole vertical PCB orientation
Wire gauge compatibility: 12-28 AWG acceptance range
Regulatory compliance: ROHS3 and REACH status

The substitute part HM0590800000G (Amphenol Anytek) meets all these criteria with identical mechanical and electrical specifications. The substitute maintains the same pitch, position count, termination technology, and mounting method. Both parts are ROHS3 compliant and REACH unaffected.

Engineering Selection Recommendations

The HM0590800000G from Amphenol Anytek is a direct functional equivalent to the obsolete OSTHM059080. Both components satisfy identical electrical and mechanical requirements for 5-position, 7.5mm pitch wire-to-board terminal block applications.

The substitute part offers the following advantages:

Active product status: HM0590800000G 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
Improved contact plating: Tin-plated brass contacts provide enhanced corrosion resistance compared to unplated brass
Regulatory compliance: Both ROHS3 and REACH certifications are maintained

For applications requiring the OSTHM059080, the HM0590800000G provides equivalent performance with superior long-term availability and enhanced environmental performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can HM0590800000G be used as a direct replacement for OSTHM059080 in existing designs?

A: Yes. Both parts share identical pitch (7.5mm), position count (5), electrical ratings (8A/250V), wire gauge acceptance (12-28 AWG), and termination method (screwless push-in spring). PCB footprints and mounting hole patterns are compatible.

Q: What is the difference in contact material between the two parts?

A: The OSTHM059080 uses unplated brass contacts, while the HM0590800000G uses tin-plated brass contacts. Tin plating provides enhanced corrosion resistance and is suitable for applications with higher environmental exposure requirements.

Q: Does the wider operating temperature range of HM0590800000G affect compatibility?

A: No. The substitute's extended temperature range (-40°C to 115°C versus -30°C to 105°C) is a performance enhancement that does not impact compatibility. Applications operating within the original temperature specification remain fully supported.

Q: Are both parts RoHS3 compliant?

A: Yes. Both OSTHM059080 and HM0590800000G are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing.

Q: What packaging is available for the substitute part?

A: HM0590800000G is supplied in bulk packaging. Verify packaging requirements with your procurement specification before ordering.
