Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM028080 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 positions per level, 10mm pitch spacing, and vertical-with-board mating orientation are non-negotiable
• Termination Method: Screwless push-in spring termination must be maintained
• Mounting: Through-hole PCB mounting is required
• Material Compatibility: Thermoplastic housing with brass contacts ensures functional equivalence

The substitute part HM0280800000G manufactured by Amphenol Anytek meets all these criteria, providing a direct functional replacement for the obsolete OSTHM028080.

Parameter Comparison

Engineering Selection Recommendations

The HM0280800000G from Amphenol Anytek is the direct equivalent for the obsolete OSTHM028080. Selection of this substitute is supported by:

• Functional Equivalence: All critical electrical and mechanical parameters match or exceed the original specification
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status
• Product Availability: The substitute is active in production with confirmed inventory, ensuring supply chain continuity
• Enhanced Performance: The Amphenol part provides extended operating temperature range (-40°C to 115°C versus -30°C to 105°C) and tin-plated brass contacts, offering improved corrosion resistance

Frequently Asked Questions (FAQ)

Q: Can HM0280800000G be used as a direct replacement for OSTHM028080 in existing PCB designs?

A: Yes. The HM0280800000G maintains identical pitch spacing (10mm), through-hole mounting footprint, and electrical ratings (8A, 250V). No PCB layout modifications are required.

Q: Are there differences in wire termination between these parts?

A: Both parts utilize identical screwless push-in spring termination. Wire gauge acceptance (12-28 AWG) and insertion/extraction methods are equivalent.

Q: What is the significance of tin plating on the Amphenol substitute?

A: Tin plating on the brass contacts provides enhanced corrosion resistance compared to unplated brass, extending component life in humid or corrosive environments while maintaining electrical performance.

Q: Does the extended temperature range of HM0280800000G affect compatibility?

A: No. The extended operating range (-40°C to 115°C) of the Amphenol part is a superset of the original specification (-30°C to 105°C), ensuring compatibility across all original application conditions.

Q: Are both parts RoHS compliant?

A: Yes. Both OSTHM028080 and HM0280800000G are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.
