Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM064080 is determined by strict equivalence across the following critical parameters:

• Position count and pitch spacing (6 positions at 0.300" / 7.62mm)
• Mating orientation (vertical with board configuration)
• Wire termination method (screwless push-in spring technology)
• Mounting interface (through-hole PCB mounting)
• Wire gauge compatibility (12-28 AWG acceptance range)

The substitute part HM0640800000G manufactured by Amphenol Anytek meets all these core requirements. While the substitute exhibits enhanced electrical ratings (300 V vs. 250 V) and extended operating temperature range (-40°C ~ 115°C vs. -30°C ~ 105°C), these represent improvements that maintain backward compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

The HM0640800000G from Amphenol Anytek is a direct functional equivalent to the obsolete OSTHM064080. Both components maintain identical mechanical and electrical core specifications, ensuring pin-for-pin compatibility in existing PCB designs. The substitute part carries active product status with current manufacturing support, addressing the obsolescence constraint of the original component.

Both parts satisfy ROHS3 compliance and REACH unaffected status, maintaining regulatory alignment for applications requiring these certifications. The substitute's enhanced voltage rating (300 V) and extended temperature operating range (-40°C ~ 115°C) provide additional design margin without introducing incompatibility. The tin-plated brass contact material in the substitute offers improved corrosion resistance compared to the unplated brass of the original.

Frequently Asked Questions (FAQ)

Q: Can HM0640800000G be used as a direct replacement for OSTHM064080 in existing designs?

A: Yes. Both components share identical position count, pitch spacing, mating orientation, wire termination method, and mounting interface. The substitute meets or exceeds all electrical and thermal specifications of the original part.

Q: What is the primary reason for substitution?

A: The OSTHM064080 is classified as obsolete. The HM0640800000G maintains active product status with current manufacturing availability, ensuring long-term procurement continuity.

Q: Are there differences in contact material between these parts?

A: The OSTHM064080 uses unplated brass contacts, while the HM0640800000G features tin-plated brass contacts. Tin plating provides enhanced corrosion resistance and is compatible with the same wire gauge range and termination method.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status for applications requiring these certifications.

Q: What is the voltage and temperature margin provided by the substitute?

A: The HM0640800000G provides a 50 V higher voltage rating (300 V vs. 250 V) and an extended operating temperature range of -40°C to 115°C compared to the original -30°C to 105°C specification.

Q: Are the packaging formats compatible?

A: The OSTHM064080 is supplied in standard packaging, while the HM0640800000G is supplied in bulk packaging. Both formats contain the same component and are suitable for PCB assembly processes.
