Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM084080 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Positions per level (8), pitch spacing (0.300"/7.62mm), current rating (8A minimum), voltage rating (250V minimum), and wire gauge acceptance (12-28 AWG)
• Mechanical Compatibility: Vertical with board mating orientation, through-hole mounting, push-in spring termination method, and gray color housing
• Environmental Compliance: RoHS3 compliance, REACH unaffected status, and operating temperature range capability

The substitute part HM0840800000G manufactured by Amphenol Anytek meets all critical substitution criteria. This part maintains identical electrical and mechanical specifications while offering enhanced voltage rating (300V vs. 250V) and extended operating temperature range (-40°C ~ 115°C vs. -30°C ~ 105°C). The substitute is classified as active product status, ensuring continued availability and supply chain support.

Parameter Comparison

Engineering Selection Recommendations

The HM0840800000G from Amphenol Anytek is a direct functional equivalent for the obsolete OSTHM084080. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

The substitute part provides enhanced electrical performance through increased voltage rating (300V vs. 250V) and extended operating temperature range (-40°C ~ 115°C vs. -30°C ~ 105°C), making it suitable for applications with more demanding environmental or electrical specifications. The tin-plated brass contact material in the substitute offers improved corrosion resistance compared to the base brass plating of the original part.

Active product status of the substitute ensures long-term availability, supply chain continuity, and manufacturer support, addressing the obsolescence of the original component.

Frequently Asked Questions (FAQ)

Q: Can HM0840800000G be used as a direct replacement for OSTHM084080 in existing designs?

A: Yes. Both parts share identical electrical ratings (8A, 250V minimum), mechanical configuration (8 positions, 0.300" pitch, vertical through-hole mounting), and wire termination method (push-in spring). PCB footprints and mounting hole patterns are compatible. The substitute meets or exceeds all original specifications.

Q: What are the key differences between these parts?

A: The substitute offers enhanced voltage rating (300V vs. 250V), extended operating temperature range (-40°C ~ 115°C vs. -30°C ~ 105°C), and tin-plated brass contacts versus base brass. The original part is obsolete; the substitute is active product.

Q: Are there packaging differences between OSTHM084080 and HM0840800000G?

A: The original part packaging is not specified in available documentation. The substitute is supplied in bulk packaging. Confirm packaging requirements for your procurement process.

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

A: Yes. Both parts accept wire gauges from 12-28 AWG, maintaining identical wire termination compatibility.

Q: Are regulatory certifications equivalent?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements for equivalent component selection.

Q: What is the inventory status of these parts?

A: OSTHM084080 has 648 pieces in stock (obsolete status). HM0840800000G has 826 pieces in stock (active status), providing superior supply chain availability.
