OSTHM235080 Equivalent & Substitute Parts

Part Overview

The OSTHM235080 is a 23-position wire-to-board terminal block manufactured by On-Shore Technology, designed for vertical PCB mounting with 0.200" (5.08mm) 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 active equivalent components to maintain design continuity and ensure supply chain availability for new production and field replacements.

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM235080 is determined by strict equivalence across the following critical parameters:

Position Count & Pitch: 23 positions at 0.200" (5.08mm) spacing (mechanical interchangeability)
Electrical Ratings: 8A current and 250V voltage (functional equivalence)
Wire Gauge Compatibility: 12-28 AWG acceptance (termination compatibility)
Mounting Configuration: Through-hole vertical orientation (PCB assembly compatibility)
Termination Method: Screwless push-in spring mechanism (assembly process compatibility)
Compliance: ROHS3 compliance and REACH unaffected status (regulatory equivalence)

The substitute part HM2350800000G by Amphenol Anytek meets all these criteria and is classified as a direct equivalent.

Engineering Selection Recommendations

The HM2350800000G is the direct equivalent for OSTHM235080 applications. Selection is based on the following engineering factors:

Product Status: The substitute part maintains active production status, ensuring long-term supply availability and manufacturing consistency compared to the obsolete original part.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and hazardous substance regulations.

Electrical & Mechanical Equivalence: Identical ratings across current, voltage, wire gauge, pitch, and position count ensure drop-in compatibility without circuit redesign or PCB layout modification.

Enhanced Operating Range: The substitute part extends the operating temperature range to -40°C ~ 115°C, providing broader environmental tolerance than the original specification of -30°C ~ 105°C.

Contact Plating Enhancement: Tin plating on the brass contacts in the substitute part provides improved corrosion resistance and contact reliability compared to unplated brass.

Frequently Asked Questions (FAQ)

Q: Can HM2350800000G be used as a direct replacement for OSTHM235080 without PCB modification?

A: Yes. Both components share identical pitch (0.200"), position count (23), mounting type (through-hole vertical), and footprint geometry. No PCB layout changes are required.

Q: Are the electrical ratings identical between the two parts?

A: Yes. Both components are rated for 8A at 250V and accept wire gauges from 12-28 AWG. Electrical performance is equivalent.

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

A: The original OSTHM235080 uses unplated brass contacts. The substitute HM2350800000G uses tin-plated brass contacts, which provide enhanced corrosion resistance and improved contact reliability in field applications.

Q: Does the extended operating temperature range of HM2350800000G affect compatibility?

A: No. The substitute part's extended range (-40°C ~ 115°C versus -30°C ~ 105°C) is a performance enhancement that maintains full compatibility with the original specification envelope.

Q: Are both parts RoHS3 compliant?

A: Yes. Both OSTHM235080 and HM2350800000G are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the packaging difference between these parts?

A: OSTHM235080 was supplied in standard packaging. HM2350800000G is supplied in bulk packaging. Verify bulk quantity requirements with your procurement specifications.
