Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTKH080550 is determined by strict equivalence across the following critical parameters:

• 8-position configuration with 0.250" (6.35mm) pitch
• Vertical with board mating orientation
• Through-hole PCB mounting
• Screw-pressure clip wire termination method
• M3 screw thread with 0.49 Nm torque specification
• 30 A current and 300 V voltage ratings
• 10-24 AWG wire gauge compatibility

The substitute part KH0805500000G meets all these criteria, ensuring mechanical and electrical interchangeability within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The KH0805500000G from Amphenol Anytek is a direct functional equivalent to the OSTKH080550. Both components maintain identical electrical and mechanical specifications across all critical parameters, including current capacity, voltage rating, pitch, wire gauge compatibility, and screw termination specifications.

The KH0805500000G offers the advantage of active product status with current manufacturing support, ensuring long-term availability and supply chain stability. Both parts carry ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial applications.

The KH0805500000G provides an extended operating temperature range (-40°C ~ 115°C versus -30°C ~ 105°C), offering improved thermal performance in demanding environments. This enhanced specification does not introduce incompatibility and represents a performance advantage for temperature-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can KH0805500000G be used as a direct replacement for OSTKH080550 in existing designs?

A: Yes. Both components share identical pitch (0.250"), position count (8), mating orientation (vertical with board), current rating (30 A), voltage rating (300 V), wire gauge range (10-24 AWG), and screw termination specifications (M3 thread, 0.49 Nm torque). PCB footprints and assembly procedures remain unchanged.

Q: What is the primary reason to substitute the OSTKH080550?

A: The OSTKH080550 carries obsolete product status. The KH0805500000G maintains active manufacturing status, ensuring reliable supply availability and continued technical support.

Q: Are there differences in material composition between these parts?

A: Both components use thermoplastic housing with identical contact and clamp materials. The OSTKH080550 specifies brass-tin plated contacts, while the KH0805500000G uses steel-zinc plated contacts. Both configurations meet the electrical and mechanical requirements for the specified application parameters.

Q: Does the extended operating temperature range of KH0805500000G affect compatibility?

A: No. The extended range (-40°C ~ 115°C versus -30°C ~ 105°C) represents an enhanced specification that does not introduce incompatibility. Designs operating within the original temperature range remain fully compatible.

Q: What packaging format is available for KH0805500000G?

A: KH0805500000G is supplied in bulk packaging, suitable for high-volume production environments and automated assembly processes.
