Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTHM077080 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Current rating (8A), voltage rating (250V), and wire gauge compatibility (12-28 AWG) must remain unchanged
• Physical Configuration: 7 positions per level, 5.00mm pitch, vertical with board orientation, and through-hole mounting type are non-negotiable
• Termination Method: Screwless push-in spring termination must be maintained
• Environmental Compliance: RoHS3 compliance and REACH unaffected status required

The substitute part HM0770800000G manufactured by Amphenol Anytek meets all these criteria while offering active product status and improved operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The HM0770800000G from Amphenol Anytek is a direct functional equivalent to the obsolete OSTHM077080. 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 regulatory requirements. The HM0770800000G provides an extended operating temperature range (-40°C to 115°C versus -30°C to 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 unplated brass.

Frequently Asked Questions (FAQ)

Q: Can HM0770800000G be used as a direct replacement for OSTHM077080 in existing designs?

A: Yes. Both components share identical electrical ratings (8A, 250V), physical configuration (7 positions, 5.00mm pitch), mounting type (through-hole), and termination method (screwless push-in spring). No design modifications are required.

Q: What is the primary advantage of switching to HM0770800000G?

A: The HM0770800000G maintains active product status, ensuring long-term supply availability. The OSTHM077080 is obsolete and subject to inventory depletion.

Q: Are there differences in wire gauge compatibility?

A: No. Both parts accommodate 12-28 AWG wire gauges identically.

Q: Does the extended temperature range of HM0770800000G affect compatibility?

A: No. The extended range (-40°C to 115°C) is a superset of the original specification (-30°C to 105°C), providing additional operational margin without affecting existing applications.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the OSTHM077080 and HM0770800000G are ROHS3 compliant and REACH unaffected.

Q: What is the difference between brass and tin-plated brass contacts?

A: Tin plating provides enhanced corrosion resistance and improved contact reliability in humid or corrosive environments. Both materials are functionally compatible for standard applications.
