Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM029080 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: 2-position count, 7.5mm pitch spacing, and vertical-with-board mating orientation are non-negotiable
• Termination Technology: Screwless push-in spring termination method must be maintained
• Mounting Interface: Through-hole PCB mounting requirement must be preserved
• Environmental Compliance: RoHS3 compliance and MSL rating (1 - Unlimited) must be maintained

The substitute part HM0290800000G by Amphenol Anytek meets all these criteria, providing functional equivalence while offering improved product status (Active vs. Obsolete) and enhanced operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The HM0290800000G from Amphenol Anytek is the direct functional equivalent for OSTHM029080 applications. Both components maintain identical electrical and mechanical specifications across all critical parameters. The substitute offers two distinct advantages: active product status ensuring long-term availability and supply chain support, and an extended operating temperature range (-40°C to 115°C versus -30°C to 105°C). Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level rating. The tin-plated brass contact material in the substitute provides enhanced corrosion resistance compared to the base brass specification of the original part.

Frequently Asked Questions (FAQ)

Q: Can HM0290800000G be used as a direct replacement for OSTHM029080 in existing designs?

A: Yes. Both components share identical electrical ratings (8A, 250V), wire gauge compatibility (12-28 AWG), pitch spacing (7.5mm), and termination technology (screwless push-in spring). PCB footprints and mounting interfaces are equivalent.

Q: What is the significance of the extended temperature range in HM0290800000G?

A: The substitute operates from -40°C to 115°C compared to the original -30°C to 105°C range. This provides additional thermal margin for applications exposed to extreme environmental conditions, though both ratings satisfy standard industrial operating requirements.

Q: Does the tin plating on HM0290800000G contacts affect compatibility?

A: No. Tin plating on brass contacts is a standard enhancement that improves corrosion resistance and contact reliability. It does not affect electrical performance or mechanical compatibility with existing PCB designs.

Q: Are both parts RoHS3 compliant?

A: Yes. Both OSTHM029080 and HM0290800000G are ROHS3 compliant with MSL rating of 1 (Unlimited), meeting current regulatory requirements for electronic component manufacturing.

Q: What packaging considerations apply to HM0290800000G?

A: The substitute is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes, as the original OSTHM029080 packaging specification was not provided.
