Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM123080 is determined by strict alignment across the following critical parameters:

• 12 positions per level configuration
• 0.150" (3.81mm) pitch spacing
• Vertical with board mating orientation
• Through-hole PCB mounting
• 8A current and 300V voltage ratings
• 14-28 AWG wire gauge compatibility
• Screwless push-in spring termination method
• Thermoplastic housing construction
• Brass contact material with appropriate plating
• ROHS3 compliance and MSL 1 rating

The substitute part HM1230800000G manufactured by Amphenol Anytek meets all critical electrical and mechanical parameters required for direct substitution. This part maintains identical position count, pitch, mounting orientation, current/voltage ratings, wire gauge range, and termination method. Both parts are ROHS3 compliant with MSL 1 rating, ensuring regulatory and environmental compatibility.

Parameter Comparison

Engineering Selection Recommendations

The HM1230800000G qualifies as a direct substitute for the OSTHM123080 based on matching electrical specifications, mechanical configuration, and regulatory compliance. The OSTHM123080 is classified as Obsolete, while the HM1230800000G maintains Active product status, ensuring continued availability and manufacturing support.

Both parts carry ROHS3 compliance and MSL 1 rating, confirming equivalent environmental and moisture sensitivity classifications. The HM1230800000G features an extended operating temperature range (-40°C ~ 115°C versus -30°C ~ 105°C), providing additional thermal margin in applications requiring broader temperature performance.

Selection of the HM1230800000G eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing PCB designs utilizing the OSTHM123080.

Frequently Asked Questions (FAQ)

Q: Can HM1230800000G be used as a direct replacement for OSTHM123080 in existing designs?

A: Yes. Both parts share identical position count (12), pitch spacing (0.150"), mating orientation (vertical with board), current/voltage ratings (8A/300V), wire gauge range (14-28 AWG), and termination method (screwless push-in spring). PCB footprints and electrical performance are fully compatible.

Q: What is the primary difference between these two parts?

A: The OSTHM123080 is Obsolete, while HM1230800000G is Active. The HM1230800000G also features tin-plated brass contacts and an extended operating temperature range (-40°C ~ 115°C versus -30°C ~ 105°C).

Q: Are both parts RoHS compliant?

A: Yes. Both OSTHM123080 and HM1230800000G are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Does the tin plating on HM1230800000G contacts affect compatibility?

A: No. Tin plating on brass contacts is a standard enhancement that improves corrosion resistance and contact reliability. This does not affect mechanical or electrical compatibility with the OSTHM123080 footprint.

Q: What packaging is available for the substitute part?

A: HM1230800000G is supplied in Bulk packaging, with 836 pieces available in new original stock condition.
