OSTHM167080 Equivalent & Substitute Parts

Part Overview

The OSTHM167080 is a 16-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for vertical PCB mounting with 5.00mm pitch spacing. This component provides electrical connection between external wiring and printed circuit boards with a rated current capacity of 8A at 250V, supporting wire gauges from 12 to 28 AWG. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance, repair, and production continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM167080 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility: Identical current rating (8A), voltage rating (250V), and wire gauge acceptance (12-28 AWG)
Mechanical Compatibility: Matching position count (16), pitch spacing (5.00mm), mating orientation (vertical with board), and through-hole mounting configuration
Termination Method: Identical screwless push-in spring wire termination system
Material Specifications: Thermoplastic housing with brass contact plating and stainless steel clamp material
Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The substitute part HM1670800000G manufactured by Amphenol Anytek meets all these criteria, providing direct functional equivalence for the obsolete OSTHM167080.

Engineering Selection Recommendations

The HM1670800000G from Amphenol Anytek is the direct functional equivalent for the obsolete OSTHM167080. Both components maintain identical electrical and mechanical specifications across all critical parameters. The substitute part offers the advantage of active product status with current manufacturing support and availability (724 pcs in stock versus 867 pcs for the obsolete original).

The HM1670800000G provides an extended operating temperature range (-40°C to 115°C compared to -30°C to 105°C), offering improved thermal performance margins. The tin-plated brass contact material in the substitute part provides enhanced corrosion resistance compared to the unplated brass of the original component, while maintaining full electrical compatibility.

Both components carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future applications. The through-hole mounting footprint and push-in spring termination method are identical, allowing direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can HM1670800000G be used as a direct replacement for OSTHM167080 on existing PCBs?

A: Yes. The HM1670800000G provides identical through-hole mounting footprint, pitch spacing (5.00mm), and position count (16). No PCB layout modifications are required for substitution.

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

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

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

A: The OSTHM167080 uses unplated brass contacts, while the HM1670800000G uses tin-plated brass contacts. Tin plating provides enhanced corrosion resistance and is compatible with the same electrical specifications.

Q: Does the extended temperature range of HM1670800000G affect compatibility?

A: No. The extended operating range (-40°C to 115°C versus -30°C to 105°C) represents an improvement that maintains full backward compatibility. Applications within the original temperature range operate identically.

Q: Are both parts RoHS compliant?

A: Yes. Both OSTHM167080 and HM1670800000G are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the packaging format for the substitute part?

A: The HM1670800000G is supplied in bulk packaging, consistent with standard terminal block distribution methods.
