Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSTHM075080 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Current rating (8 A), voltage rating (250 V), and wire gauge acceptance (12-28 AWG) must remain identical
• Physical Configuration: 7 positions per level, 0.200" (5.08mm) pitch, and vertical-with-board mating orientation are non-negotiable
• Termination Technology: Screwless push-in spring termination must be maintained
• Mounting Interface: Through-hole PCB mounting is required
• Material Compatibility: Thermoplastic housing with brass contacts ensures functional equivalence

The substitute part HM0750800000G by Amphenol Anytek meets all these criteria while offering active product status and improved temperature operating range.

Parameter Comparison

Engineering Selection Recommendations

The HM0750800000G from Amphenol Anytek is a direct functional equivalent to the OSTHM075080. Both components maintain identical electrical ratings, physical dimensions, and termination characteristics. The substitute part offers the advantage of active product status, ensuring continued availability and supply chain reliability. Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The HM0750800000G provides an extended operating temperature range (-40°C ~ 115°C versus -30°C ~ 105°C), which may provide additional thermal margin in demanding applications. The tin-plated brass contact material in the substitute part offers enhanced corrosion resistance compared to standard brass plating.

Frequently Asked Questions (FAQ)

Q: Can HM0750800000G be used as a direct replacement for OSTHM075080 in existing designs?

A: Yes. Both components share identical electrical specifications (8 A, 250 V), physical configuration (7 positions, 5.08mm pitch), mounting interface (through-hole), and termination technology (screwless push-in spring). PCB footprints and electrical performance are equivalent.

Q: What is the primary advantage of switching to HM0750800000G?

A: The HM0750800000G maintains active product status, ensuring long-term supply availability. The OSTHM075080 is obsolete and subject to inventory depletion. Additionally, the substitute offers an extended operating temperature range and tin-plated contacts for improved corrosion resistance.

Q: Are there any compatibility concerns with wire gauge or current capacity?

A: No. Both parts accept 12-28 AWG wire and are rated for 8 A continuous current. Electrical performance and wire termination characteristics are identical.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the OSTHM075080 and HM0750800000G are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the difference in contact plating between the two parts?

A: The OSTHM075080 uses standard brass contacts, while the HM0750800000G uses tin-plated brass. Tin plating provides enhanced corrosion resistance and is suitable for applications requiring extended shelf life or exposure to corrosive environments.

Q: Are there packaging differences between these parts?

A: The OSTHM075080 is supplied in standard packaging, while the HM0750800000G is supplied in bulk packaging. Both are suitable for PCB assembly; bulk packaging may offer cost advantages for high-volume production.
