Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM185080 is determined by strict equivalence across the following critical parameters:

• 18 positions per level configuration
• 0.200" (5.08mm) pitch spacing
• Vertical with board mating orientation
• Through-hole PCB mounting
• 8A current and 250V voltage minimum ratings
• 12-28 AWG wire gauge compatibility
• Screwless push-in spring termination method
• Thermoplastic housing construction
• Brass contact material
• Gray color specification
• ROHS3 compliance

The substitute part HM1850800000G by Amphenol Anytek meets all these criteria, with enhanced operating temperature range and tin-plated brass contacts.

Parameter Comparison

Engineering Selection Recommendations

The HM1850800000G is a direct functional equivalent to the OSTHM185080 across all critical electrical and mechanical parameters. The substitute part maintains identical pitch, position count, current/voltage ratings, and termination methodology. Both components satisfy ROHS3 and REACH compliance requirements.

The HM1850800000G offers extended operating temperature range (-40°C to 115°C versus -30°C to 105°C) and tin-plated brass contacts, which provide enhanced corrosion resistance compared to unplated brass. The substitute part carries active product status with confirmed inventory availability, addressing the obsolescence of the original OSTHM185080.

Frequently Asked Questions (FAQ)

Q: Can HM1850800000G be used as a direct replacement for OSTHM185080 in existing designs?

A: Yes. Both parts share identical pitch (5.08mm), position count (18), electrical ratings (8A/250V), wire gauge compatibility (12-28 AWG), mounting type (through-hole), and termination method (screwless push-in spring). PCB footprints and connector interfaces are compatible.

Q: What is the difference between the contact materials?

A: OSTHM185080 uses unplated brass contacts. HM1850800000G uses tin-plated brass contacts, which provide improved corrosion resistance and oxidation protection in high-humidity or corrosive environments.

Q: Are there packaging differences between these parts?

A: OSTHM185080 packaging is not specified in available documentation. HM1850800000G is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Do both parts meet the same compliance standards?

A: Yes. Both OSTHM185080 and HM1850800000G are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements.

Q: What is the temperature operating range difference?

A: OSTHM185080 operates from -30°C to 105°C. HM1850800000G operates from -40°C to 115°C, providing a wider temperature envelope suitable for extended environmental applications.
