Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM027080 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 remain identical
• Physical Configuration: 2 positions per level, 5.00mm pitch, vertical board orientation, and through-hole mounting must be maintained
• Termination Method: Screwless push-in spring termination is required
• Housing & Contact Materials: Thermoplastic housing with brass contacts ensures mechanical and electrical compatibility

The substitute part HM0270800000G 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 HM0270800000G serves as a direct functional equivalent to the OSTHM027080. Both components maintain identical electrical and mechanical specifications across all critical parameters. The substitute part offers the following advantages:

• Product Availability: Active product status ensures continued supply and manufacturing support, eliminating obsolescence risk
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental standards
• Enhanced Operating Range: The HM0270800000G extends the upper operating temperature limit to 115°C (versus 105°C) and lower limit to -40°C (versus -30°C), providing broader thermal performance envelope
• Contact Plating: Tin plating on brass contacts in the substitute part provides enhanced corrosion resistance compared to unplated brass

For applications requiring the OSTHM027080, the HM0270800000G can be selected without design modification or performance compromise.

Frequently Asked Questions (FAQ)

Q: Can HM0270800000G be used as a direct replacement for OSTHM027080 in existing designs?

A: Yes. Both components share identical electrical ratings (8A, 250V), wire gauge compatibility (12-28 AWG), pitch spacing (5.00mm), and termination method (screwless push-in spring). Physical footprint and PCB mounting are equivalent, requiring no design changes.

Q: What is the significance of the tin plating on the HM0270800000G contacts?

A: Tin plating enhances corrosion resistance and improves contact reliability over extended service life, particularly in environments with moisture or chemical exposure. This represents a material upgrade while maintaining electrical equivalence.

Q: Are there packaging differences between these parts?

A: The OSTHM027080 is listed with unspecified packaging, while HM0270800000G is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited), ensuring equivalent regulatory and environmental compliance.

Q: Which part should be selected for new designs?

A: The HM0270800000G is recommended for new designs due to active product status, ensuring long-term availability and manufacturing support. The extended operating temperature range also provides additional design margin for thermal applications.
