Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM183080 is determined by strict equivalence across the following critical parameters:

• 18 positions per level configuration
• 0.150" (3.81mm) pitch spacing
• Vertical with board mating orientation
• Through-hole PCB mounting
• 8A current and 300V voltage ratings
• 14-28 AWG wire gauge compatibility
• Screwless push-in spring termination method
• Thermoplastic housing construction

The substitute part HM1830800000G manufactured by Amphenol Anytek meets all these criteria, ensuring mechanical and electrical compatibility with the original OSTHM183080 design.

The substitute part offers an extended operating temperature range (-40°C to 115°C versus -30°C to 105°C) and tin-plated brass contacts, providing enhanced environmental performance. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity classification. The active product status of HM1830800000G ensures ongoing availability and supply chain continuity for new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Can HM1830800000G be used as a direct replacement for OSTHM183080 in existing PCB designs?

A: Yes. Both components share identical pitch spacing (0.150"), position count (18), mounting type (through-hole), and electrical ratings (8A, 300V). No PCB layout modifications are required.

Q: What is the difference in operating temperature ranges between these parts?

A: The OSTHM183080 operates from -30°C to 105°C, while the HM1830800000G operates from -40°C to 115°C. The substitute part provides a wider temperature envelope suitable for extended environmental applications.

Q: Are the contact materials compatible?

A: Both parts use brass contacts. The HM1830800000G features tin plating on the brass contacts, which provides improved corrosion resistance compared to the unplated brass of the OSTHM183080.

Q: Do both parts support the same wire gauge range?

A: Yes. Both components accept 14-28 AWG wire, ensuring compatibility with existing wiring harnesses and termination practices.

Q: What is the packaging difference between these parts?

A: The OSTHM183080 is listed with no specified packaging designation, while the HM1830800000G is supplied in bulk packaging. Verify packaging requirements with your procurement specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the OSTHM183080 and HM1830800000G are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.
