Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSTHM227080 is determined by strict equivalence across the following critical parameters:

• Position Count & Pitch: 22 positions at 0.197" (5.00mm) spacing
• Electrical Ratings: 8A current, 250V voltage
• Wire Gauge Compatibility: 12-28 AWG acceptance
• Termination Method: Screwless push-in spring mechanism
• Mounting Configuration: Through-hole vertical orientation
• Housing & Contact Materials: Thermoplastic housing with brass contacts

The substitute part HM2270800000G manufactured by Amphenol Anytek meets all these criteria and is classified as active product status, providing supply continuity for the obsolete OSTHM227080.
