OSTHM098081 Equivalent & Substitute Parts

Part Overview

The OSTHM098081 is a 9-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for vertical mounting with press-fit installation on PCBs. This component features a 10mm (0.394") pitch and supports wire gauges from 12-28 AWG with a rated current of 8A at 250V. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSTHM098081 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Current rating (8A), voltage rating (250V), and wire gauge acceptance (12-28 AWG) must be identical or exceed the original specification
• Physical Compatibility: Position count (9), pitch (10mm), and mating orientation (vertical with board) must match exactly
• Termination Method: Wire termination type (screwless push-in spring) must be functionally equivalent
• Environmental Compliance: RoHS3 compliance and operating temperature range must meet or exceed original specifications
• Mounting Interface: Mounting type must support press-fit installation on PCBs

The substitute part HM0980810000G by Amphenol Anytek meets all these criteria while offering improved product status (active vs. obsolete) and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The HM0980810000G from Amphenol Anytek is a direct functional equivalent to the obsolete OSTHM098081. Both components maintain identical electrical ratings, physical dimensions, and termination characteristics. The substitute part offers the advantage of active product status, ensuring long-term availability and supply chain continuity.

The HM0980810000G supports both through-hole and press-fit mounting options, providing installation flexibility beyond the original press-fit-only design. The extended operating temperature range (-40°C to 115°C versus -30°C to 105°C) provides additional thermal margin for demanding applications. Both parts maintain ROHS3 compliance and equivalent environmental ratings.

For applications currently using OSTHM098081, direct substitution with HM0980810000G requires no circuit redesign or PCB layout modification, as all critical parameters remain equivalent.

Frequently Asked Questions (FAQ)

Q: Can HM0980810000G be used as a direct replacement for OSTHM098081 without PCB redesign?

A: Yes. Both components share identical pitch (10mm), position count (9), mating orientation (vertical with board), and electrical ratings (8A, 250V). No PCB layout changes are required.

Q: What is the difference in mounting type between the two parts?

A: OSTHM098081 supports press-fit mounting only. HM0980810000G supports both through-hole and press-fit mounting, providing installation flexibility while maintaining compatibility with existing press-fit PCB designs.

Q: Are there any compliance differences between the substitute and original part?

A: Both parts are ROHS3 compliant and REACH unaffected. The substitute part offers an extended operating temperature range (-40°C to 115°C) compared to the original (-30°C to 105°C).

Q: Does the tin plating on the substitute part affect compatibility?

A: No. Tin plating on brass contacts is a standard enhancement that improves corrosion resistance and solderability while maintaining electrical equivalence with unplated brass contacts.

Q: What wire gauges are supported by the substitute part?

A: The HM0980810000G accepts wire gauges from 12-28 AWG, identical to the original OSTHM098081.

Q: Is the substitute part currently available?

A: Yes. HM0980810000G has active product status with 1134 units in stock, compared to the obsolete OSTHM098081.
