Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSTHM023081 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Current rating (8 A), voltage rating (300 V), and wire gauge range (14-28 AWG) must be identical
• Physical Compatibility: Pitch (0.150" / 3.81mm), number of positions (2), and mating orientation (vertical with board) must match exactly
• Termination Method: Wire termination type (screwless leg spring, push-in spring) must be equivalent
• Mechanical Mounting: Mounting method must support press-fit installation
• Material and Environmental: Housing material (thermoplastic), contact material (brass-based), and operating temperature range must be compatible

The substitute part HM0230810000G from Amphenol Anytek meets all these criteria while offering enhanced temperature range (-40°C ~ 115°C) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The HM0230810000G from Amphenol Anytek is a direct functional equivalent to the OSTHM023081. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The substitute part offers the advantage of active product status, ensuring continued availability and supply chain stability. The extended operating temperature range (-40°C ~ 115°C versus -30°C ~ 105°C) provides additional thermal margin for demanding applications. The tin-plated brass contact material in the substitute part enhances corrosion resistance compared to the base brass contacts of the original part. Both components support identical electrical specifications and mechanical mounting configurations, enabling direct substitution in PCB designs.

Frequently Asked Questions (FAQ)

Q: Can HM0230810000G replace OSTHM023081 in existing designs? A: Yes. Both parts share identical pitch (3.81mm), position count (2), current rating (8 A), voltage rating (300 V), wire gauge range (14-28 AWG), and termination method. The substitute part is electrically and mechanically compatible.

Q: What is the difference in mounting between the two parts? A: The OSTHM023081 uses press-fit mounting only. The HM0230810000G supports both through-hole and press-fit mounting, providing additional installation flexibility while maintaining press-fit capability.

Q: Does the extended temperature range of HM0230810000G affect compatibility? A: No. The extended range (-40°C ~ 115°C) is a superset of the original specification (-30°C ~ 105°C). Applications operating within the original temperature range will function identically in both parts.

Q: Are there packaging differences between these parts? A: The OSTHM023081 packaging is not specified in the original documentation. The HM0230810000G is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Why is the original part obsolete? A: The OSTHM023081 is listed as obsolete by On Shore Technology Inc. The HM0230810000G maintains active product status, ensuring long-term availability and support.

Q: Is the tin plating on HM0230810000G contacts significant? A: Tin plating provides enhanced corrosion resistance and improved solderability compared to bare brass. This is a material enhancement that does not affect electrical performance in standard applications.
