Substitute Part Grouping Explanation

Substitution of the OSTHM094081 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility: Positions per level (9), pitch spacing (0.300"/7.62mm), current rating (8 A minimum), voltage rating (250 V minimum), and wire gauge acceptance (12-28 AWG)
Mechanical Compatibility: Mating orientation (vertical with board), wire termination method (screwless push-in spring), and housing material (thermoplastic)
Environmental & Regulatory: Operating temperature range, RoHS3 compliance, and REACH status

The substitute part HM0940810000G meets all critical electrical and mechanical parameters while offering enhanced specifications in voltage rating (300 V vs. 250 V) and operating temperature range (-40°C ~ 115°C vs. -30°C ~ 105°C). The substitute maintains identical pitch, position count, wire gauge compatibility, and termination methodology.

Engineering Selection Recommendations

The HM0940810000G from Amphenol Anytek is a direct functional substitute for the obsolete OSTHM094081. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The substitute part is currently in active production status, providing supply chain continuity for new designs and ongoing production requirements.

The HM0940810000G offers enhanced electrical performance with a 300 V voltage rating compared to the 250 V rating of the original part, and an extended operating temperature range of -40°C ~ 115°C versus -30°C ~ 105°C. The addition of through-hole mounting capability alongside press-fit termination provides design flexibility without compromising the original press-fit functionality. Tin plating on the brass contacts in the substitute part enhances corrosion resistance compared to unplated brass.

Frequently Asked Questions (FAQ)

Q: Can HM0940810000G be used as a direct replacement for OSTHM094081 in existing designs?

A: Yes. Both components share identical pitch spacing (0.300"/7.62mm), position count (9), current rating (8 A), wire gauge compatibility (12-28 AWG), and wire termination method (screwless push-in spring). The substitute meets or exceeds all electrical and mechanical requirements of the original part.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (On Shore Technology vs. Amphenol Anytek), product status (obsolete vs. active), voltage rating (250 V vs. 300 V), operating temperature range (-30°C ~ 105°C vs. -40°C ~ 115°C), contact plating (brass vs. brass tin-plated), and mounting options (press-fit only vs. through-hole and press-fit).

Q: Does the substitute part require PCB layout modifications?

A: The substitute part maintains identical pitch and position spacing, so no PCB footprint modifications are required. However, the HM0940810000G offers both through-hole and press-fit mounting options, allowing design flexibility if through-hole mounting is preferred.

Q: Are both parts RoHS compliant?

A: Yes. Both OSTHM094081 and HM0940810000G are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the inventory status of these parts?

A: OSTHM094081 has 982 pieces in stock as new original inventory. HM0940810000G has 757 pieces in stock as new original inventory in bulk packaging.
