Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSTHM085080 terminal block is determined by strict equivalence across the following critical parameters:

• Position Count & Pitch: 8 positions at 0.200" (5.08mm) spacing
• Electrical Ratings: 8 A current capacity and 250 V voltage rating
• Wire Gauge Compatibility: 12-28 AWG acceptance range
• Mounting Configuration: Through-hole vertical PCB orientation
• Termination Method: Screwless push-in spring technology
• Environmental Compliance: ROHS3 compliance and MSL 1 rating

The substitute part HM0850800000G manufactured by Amphenol Anytek meets all these critical parameters, providing functional and mechanical equivalence for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The HM0850800000G from Amphenol Anytek is a direct functional equivalent for the obsolete OSTHM085080. Both components maintain identical electrical specifications, mechanical dimensions, and termination characteristics. The substitute part offers the advantage of active production status, ensuring long-term availability and supply chain continuity.

The HM0850800000G provides an extended operating temperature range (-40°C ~ 115°C versus -30°C ~ 105°C), which represents an improvement over the original specification. Both parts maintain ROHS3 compliance and MSL 1 moisture sensitivity ratings, supporting equivalent environmental and regulatory requirements.

The tin-plated brass contact material on the substitute part provides enhanced corrosion resistance compared to the unplated brass of the original component, supporting improved reliability in demanding environments.

Frequently Asked Questions (FAQ)

Q: Can HM0850800000G be used as a direct replacement for OSTHM085080 in existing PCB designs?

A: Yes. Both components share identical pitch spacing (0.200"), position count (8), mounting type (through-hole), and wire termination method (screwless push-in spring). PCB footprints and assembly processes require no modification.

Q: Are there differences in wire gauge acceptance between these parts?

A: No. Both components accept wire gauges from 12-28 AWG without variation.

Q: What is the significance of the extended temperature range on the substitute part?

A: The HM0850800000G operates across -40°C ~ 115°C, compared to the original -30°C ~ 105°C range. This extended specification provides additional margin for applications subject to extreme thermal conditions, though both parts meet standard industrial operating requirements.

Q: Does the tin plating on the substitute part affect compatibility?

A: No. Tin plating on the brass contacts enhances corrosion resistance and contact reliability. This represents a material improvement with no negative impact on electrical or mechanical compatibility.

Q: What is the inventory status for these parts?

A: OSTHM085080 is obsolete with 700 units in stock. HM0850800000G is in active production with 839 units currently available, providing superior long-term supply assurance.

Q: Are both parts compliant with the same regulatory standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity level). Regulatory and environmental certifications are equivalent.
