Engineering Selection Recommendations

The HM1150800000G from Amphenol Anytek is a direct functional substitute for the obsolete OSTHM115080. Both components maintain identical electrical and mechanical specifications across all critical parameters including position count, pitch, current/voltage ratings, wire gauge compatibility, and termination methodology.

The substitute part offers additional advantages: active product status ensures ongoing availability and manufacturing support, extended operating temperature range (-40°C to 115°C versus -30°C to 105°C), and enhanced contact plating (tin-plated brass versus standard brass). Both parts maintain ROHS3 compliance and MSL 1 ratings, satisfying equivalent environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can HM1150800000G be used as a direct replacement for OSTHM115080 in existing designs?

A: Yes. Both components share identical position count (11), pitch spacing (5.08mm), electrical ratings (8A/250V), wire gauge support (12-28 AWG), and termination method (screwless push-in spring). PCB footprints and mounting hole patterns are compatible.

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

A: OSTHM115080 uses standard brass contacts. HM1150800000G uses tin-plated brass contacts, which provide enhanced corrosion resistance and improved contact reliability over extended service life.

Q: Does the extended temperature range of HM1150800000G affect compatibility?

A: No. The substitute's operating range (-40°C to 115°C) encompasses the original part's range (-30°C to 105°C). This represents an enhancement with no compatibility impact.

Q: Are there packaging differences between these parts?

A: OSTHM115080 packaging is not specified in available data. HM1150800000G is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Do both parts meet the same compliance standards?

A: Yes. Both OSTHM115080 and HM1150800000G are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings.

Q: Why is OSTHM115080 classified as obsolete?

A: On Shore Technology Inc. has discontinued this part number. HM1150800000G from Amphenol Anytek provides equivalent functionality with active manufacturing status.
