Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSTHM124080 is determined by strict equivalence across the following critical parameters:

• Position count and pitch: 12 positions at 0.300" (7.62mm) spacing ensures mechanical and electrical compatibility with existing PCB layouts
• Mating orientation: Vertical with board configuration maintains identical mounting footprint
• Wire termination method: Screwless push-in spring termination provides functional equivalence for wire connection
• Wire gauge range: 12-28 AWG accommodation ensures compatibility with existing wiring harnesses
• Mounting type: Through-hole configuration preserves PCB assembly compatibility

The substitute part HM1240800000G by Amphenol Anytek meets all these criteria while offering enhanced electrical ratings and active product status.

Parameter Comparison

Engineering Selection Recommendations

The HM1240800000G serves as a direct functional substitute for the OSTHM124080 based on mechanical and electrical parameter equivalence. Both components maintain identical pitch, position count, and wire termination characteristics required for PCB assembly compatibility.

The substitute part offers operational advantages including higher voltage rating (300 V vs. 250 V), extended temperature range (-40°C to 115°C vs. -30°C to 105°C), and tin-plated brass contacts for enhanced corrosion resistance. Both components maintain ROHS3 compliance and identical current capacity (8 A).

The active product status of HM1240800000G ensures ongoing availability and supply chain continuity, addressing the obsolescence of the original OSTHM124080.

Frequently Asked Questions (FAQ)

Q: Can HM1240800000G be used as a direct replacement for OSTHM124080 in existing designs?

A: Yes. Both components share identical pitch (0.300"), position count (12), mating orientation (vertical with board), wire gauge range (12-28 AWG), and wire termination method (screwless push-in spring). PCB footprints and wiring harness connections are mechanically and electrically compatible.

Q: What are the differences between these two terminal blocks?

A: The HM1240800000G provides higher voltage rating (300 V vs. 250 V), extended operating temperature range (-40°C to 115°C vs. -30°C to 105°C), and tin-plated brass contacts versus standard brass. Current rating remains 8 A for both components.

Q: Does the higher voltage rating of HM1240800000G affect circuit design?

A: No. The higher voltage rating of the substitute part provides additional safety margin and does not require circuit modifications. Applications designed for 250 V operation remain fully compatible.

Q: Are both components RoHS compliant?

A: Yes. Both OSTHM124080 and HM1240800000G are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the packaging difference between these parts?

A: OSTHM124080 packaging is not specified in available documentation. HM1240800000G is supplied in bulk packaging. Confirm packaging requirements with procurement specifications.
