Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM055080 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Positions per level (5), pitch (0.200"/5.08mm), current rating (8 A minimum), and voltage rating (250 V minimum)
• Mechanical Compatibility: Mating orientation (vertical with board), mounting type (through hole), wire termination method (screwless push-in spring), and wire gauge acceptance (12-28 AWG)
• Environmental & Regulatory: Operating temperature range support, RoHS3 compliance, and REACH status
• Physical Form: Housing material (thermoplastic), contact plating (brass-based), and interlocking side features

The substitute part HM0550800000G meets all critical parameters for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

HM0550800000G is a direct substitute for OSTHM055080 based on electrical, mechanical, and regulatory equivalence. The substitute part is manufactured by Amphenol Anytek and maintains Active product status, ensuring ongoing availability and supply chain stability.

Both parts maintain ROHS3 compliance and REACH unaffected status. The HM0550800000G provides an extended operating temperature range (-40°C ~ 115°C versus -30°C ~ 105°C), offering improved thermal performance margins. The tin-plated brass contact material in the substitute part provides enhanced corrosion resistance compared to the base brass plating of the original part.

Selection of HM0550800000G eliminates obsolescence risk while maintaining full functional and mechanical compatibility with existing PCB designs utilizing the OSTHM055080.

Frequently Asked Questions (FAQ)

Q: Can HM0550800000G be used as a direct replacement for OSTHM055080 on existing PCBs?

A: Yes. Both parts share identical pitch (0.200"/5.08mm), position count (5), mounting type (through hole), and wire termination method (screwless push-in spring). PCB footprints and wire gauge acceptance (12-28 AWG) are equivalent.

Q: What are the key differences between these parts?

A: The primary differences are manufacturer (On Shore Technology Inc. versus Amphenol Anytek), product status (Obsolete versus Active), and operating temperature range (HM0550800000G extends to -40°C and 115°C). Contact plating differs slightly (tin-plated brass versus base brass), which improves corrosion resistance.

Q: Are there packaging differences?

A: OSTHM055080 packaging is listed as unspecified. HM0550800000G is supplied in Bulk packaging. Verify packaging requirements for your procurement process.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: What is the current inventory status?

A: OSTHM055080 has 1058 pcs in stock (obsolete status). HM0550800000G has 974 pcs in stock (active status). For long-term supply assurance, HM0550800000G is the recommended selection.
