Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM104080 is determined by strict equivalence across the following critical parameters:

• Mechanical Compatibility: 10 positions, 0.300" (7.62mm) pitch, vertical with board orientation, through-hole mounting
• Electrical Performance: Wire gauge acceptance (12-28 AWG), current capacity (minimum 8A), voltage rating (minimum 250V)
• Termination Method: Screwless push-in spring configuration
• Environmental Compliance: ROHS3 compliance, MSL rating of 1 (Unlimited)

The substitute part HM1040800000G manufactured by Amphenol Anytek meets all critical substitution criteria while offering enhanced electrical ratings and an active product status.

Parameter Comparison

Engineering Selection Recommendations

The HM1040800000G qualifies as a direct substitute for the OSTHM104080 based on mechanical and electrical parameter equivalence. The substitute part provides the following advantages:

• Active Product Status: HM1040800000G maintains active manufacturing status, ensuring long-term supply chain availability compared to the obsolete OSTHM104080
• Enhanced Electrical Ratings: Voltage rating increased from 250V to 300V provides additional design margin
• Extended Operating Range: Temperature range expanded from -30°C ~ 105°C to -40°C ~ 115°C accommodates broader environmental applications
• Regulatory Compliance: Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring equivalent environmental and regulatory standing

Frequently Asked Questions (FAQ)

Q: Can HM1040800000G be used as a direct replacement for OSTHM104080 in existing designs?

A: Yes. Both parts share identical mechanical pitch (0.300"), position count (10), mounting orientation (vertical with board), and wire termination method (screwless push-in spring). Electrical specifications of HM1040800000G meet or exceed OSTHM104080 requirements.

Q: What are the key differences between these parts?

A: HM1040800000G offers higher voltage rating (300V vs 250V), extended operating temperature range (-40°C to 115°C vs -30°C to 105°C), and active product status. Current rating and wire gauge acceptance remain identical.

Q: Are there any packaging considerations when switching to HM1040800000G?

A: HM1040800000G is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both OSTHM104080 and HM1040800000G are ROHS3 compliant with MSL 1 (Unlimited) rating and REACH unaffected status.

Q: What wire gauges are supported by HM1040800000G?

A: HM1040800000G accepts wire gauges from 12-28 AWG, identical to the OSTHM104080.
