Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSTKH100550 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Current rating (30A), voltage rating (300V), and wire gauge acceptance (10-24 AWG) must match exactly
• Mechanical Compatibility: Position count (10), pitch spacing (0.250"/6.35mm), mating orientation (vertical with board), and mounting method (through hole) must be identical
• Termination Method: Screw-pressure clip termination with M3 thread and 0.49 Nm torque specification must be maintained
• Physical Interface: Interlocking side features and green color designation ensure proper PCB integration

The substitute part KH1005500000G by Amphenol Anytek meets all these criteria while offering active product status and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The KH1005500000G serves as a direct functional equivalent to the OSTKH100550 across all critical electrical and mechanical parameters. Both components maintain identical current, voltage, and wire gauge specifications, ensuring seamless integration into existing circuit designs. The substitute part carries active product status with confirmed inventory availability, eliminating supply chain risk associated with the obsolete OSTKH100550.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The KH1005500000G provides an extended operating temperature range (-40°C to 115°C versus -30°C to 105°C), offering improved thermal performance in demanding environments without compromising compatibility.

Selection of the KH1005500000G is appropriate for direct replacement in new designs, repair applications, and system upgrades where the OSTKH100550 is no longer available.

Frequently Asked Questions (FAQ)

Q: Can KH1005500000G be used as a direct replacement for OSTKH100550 in existing PCB designs?

A: Yes. Both components share identical pitch spacing (0.250"/6.35mm), position count (10), mounting method (through hole), and termination specifications (M3 screw with 0.49 Nm torque). PCB footprints are mechanically and electrically compatible without modification.

Q: What are the key differences between these two parts?

A: The primary differences are product status and operating temperature range. The OSTKH100550 is obsolete with a -30°C to 105°C operating range, while the KH1005500000G is active with an extended -40°C to 115°C range. All electrical and mechanical specifications remain identical.

Q: Are there any compliance or certification differences?

A: Both parts maintain ROHS3 compliance and REACH unaffected status. No compliance gaps exist between the two components.

Q: What wire gauges are supported by the KH1005500000G?

A: The substitute part accepts wire gauges from 10-24 AWG, matching the original OSTKH100550 specification.

Q: Is the packaging format different between these parts?

A: The OSTKH100550 is supplied in standard packaging, while the KH1005500000G is supplied in bulk packaging. Both formats contain the same component with identical electrical and mechanical properties.
