Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTKH110550 is determined by strict equivalence across the following critical parameters:

• 11 positions per level configuration
• 0.250" (6.35mm) pitch spacing
• Vertical with board mating orientation
• 30 A current rating
• 300 V voltage rating
• 10-24 AWG wire gauge acceptance
• Through-hole mounting type
• Screw-pressure clip termination method
• M3 screw thread specification
• ROHS3 compliance certification

The substitute part KH1105500000G by Amphenol Anytek meets all these critical parameters, establishing direct functional and mechanical compatibility with the OSTKH110550.

Parameter Comparison

Engineering Selection Recommendations

The KH1105500000G terminal block by Amphenol Anytek is a direct functional equivalent to the OSTKH110550. Both components satisfy identical electrical specifications (30 A, 300 V), mechanical configuration (11 positions, 6.35mm pitch, through-hole mounting), and regulatory requirements (ROHS3 compliance, REACH unaffected status).

The KH1105500000G carries Active product status with current inventory availability, whereas the OSTKH110550 is Obsolete. The substitute part operates across an extended temperature range (-40°C ~ 115°C versus -30°C ~ 105°C), providing additional thermal margin for demanding applications.

Selection of KH1105500000G ensures regulatory compliance, supply chain continuity, and long-term component availability for new designs or production support.

Frequently Asked Questions (FAQ)
