Regulatory Compliance: Maintains ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements
Contact Plating Enhancement: Tin-plated brass contacts provide improved corrosion resistance compared to unplated brass

Both components are ROHS3 compliant and REACH unaffected, confirming suitability for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can HM0730800000G be used as a direct replacement for OSTHM073080 in existing designs?

A: Yes. The HM0730800000G meets all electrical and mechanical specifications of the OSTHM073080, including current rating (8A), voltage rating (300V), pitch (0.150"), position count (7), and wire termination method (screwless push-in spring). PCB footprint and mounting hole patterns are compatible.

Q: What is the primary reason for substitution?

A: The OSTHM073080 is classified as Obsolete. The HM0730800000G is an Active product from Amphenol Anytek, ensuring reliable supply availability and eliminating long-term sourcing constraints.

Q: Are there differences in operating temperature specifications?

A: The HM0730800000G operates across -40°C ~ 115°C, which exceeds the OSTHM073080 range of -30°C ~ 105°C. This extended range provides additional environmental flexibility without compromising compatibility within the original specification window.

Q: Does the tin plating on HM0730800000G contacts affect compatibility?

A: No. Tin plating on brass contacts is a material enhancement that improves corrosion resistance and contact reliability. It does not affect electrical or mechanical compatibility with the OSTHM073080 footprint or mating interfaces.

Q: Are both parts ROHS3 compliant?

A: Yes. Both OSTHM073080 and HM0730800000G are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What wire gauges are supported?

A: Both components accept wire gauges from 14-28 AWG, supporting identical conductor sizing requirements.

Q: Is the packaging format a consideration for substitution?

A: The OSTHM073080 packaging format is not specified in the original documentation. The HM0730800000G is supplied in Bulk packaging. Verify packaging requirements for your procurement and assembly processes.
