Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSTKH080551 is determined by strict equivalence across the following critical parameters:

• 8 positions per level configuration
• 0.250" (6.35mm) pitch spacing
• Horizontal with board mating orientation
• 30 A current rating and 300 V voltage rating
• 10-24 AWG wire gauge compatibility
• Through-hole mounting footprint
• Screw-pressure clip termination method
• M3 screw thread specification
• 0.49 Nm (4.3 Lb-In) torque requirement

The substitute part KH0805510000G manufactured by Amphenol Anytek meets all these electrical and mechanical parameters, enabling direct functional replacement in applications currently using the OSTKH080551.

Parameter Comparison

Engineering Selection Recommendations

The KH0805510000G from Amphenol Anytek is the direct equivalent substitute for the obsolete OSTKH080551. Both components maintain identical electrical specifications (30 A, 300 V), mechanical configuration (8 positions, 6.35mm pitch, through-hole mounting), and termination method (screw-pressure clip with M3 thread). Both parts are ROHS3 compliant and REACH unaffected, satisfying regulatory requirements for current applications.

The KH0805510000G carries active product status with confirmed inventory availability (1012 pcs), whereas the OSTKH080551 is obsolete. The substitute part offers an extended operating temperature range (-40°C ~ 115°C versus -30°C ~ 105°C), providing additional thermal margin for demanding environments.

Frequently Asked Questions (FAQ)

Q: Can KH0805510000G replace OSTKH080551 in existing designs?

A: Yes. Both parts share identical pitch (6.35mm), position count (8), current/voltage ratings (30 A/300 V), wire gauge compatibility (10-24 AWG), mounting type (through-hole), and termination method (screw-pressure clip with M3 thread). PCB footprints are mechanically and electrically compatible.

Q: What is the primary reason for substitution?

A: The OSTKH080551 is classified as obsolete. The KH0805510000G is an active product with current manufacturing and inventory support, ensuring long-term supply chain reliability.

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution.

Q: Does the extended temperature range of KH0805510000G affect compatibility?

A: No. The KH0805510000G operating range (-40°C ~ 115°C) encompasses the OSTKH080551 range (-30°C ~ 105°C). This represents an enhancement with no compatibility impact.

Q: What packaging format is available for KH0805510000G?

A: KH0805510000G is supplied in bulk packaging with 1012 pcs currently in stock.
