OSTKO112151 Equivalent & Substitute Parts

Part Overview

The OSTKO112151 is an 11-position wire-to-board terminal block manufactured by On Shore Technology Inc., designed for horizontal PCB mounting with 0.375" (9.53mm) pitch spacing. This component features a screw-type rising cage clamp termination suitable for wire gauges 10-24 AWG and rated for 30 A at 300 V operation.

The OSTKO112151 carries an Obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this terminal block specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTKO112151 is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: Substitute parts must provide exactly 11 positions at 0.375" (9.53mm) pitch to ensure PCB footprint compatibility
• Mating Orientation & Mounting: Horizontal with Board orientation and Through Hole mounting are mandatory for mechanical fit
• Wire Termination Method: Screw-type rising cage clamp termination ensures compatibility with existing wire preparation and assembly procedures
• Wire Gauge Acceptance: 10-24 AWG range must be maintained for conductor compatibility
• Operating Temperature: -40°C ~ 115°C range must be supported
• Electrical Ratings: Current and voltage ratings must meet or exceed the original specification (30 A minimum, 300 V minimum)
• Compliance: RoHS3 compliance is required for regulatory alignment

The substitute part KO1121510000G by Amphenol Anytek satisfies all critical substitution criteria and is classified as an Active product with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The KO1121510000G is a direct functional equivalent to the OSTKO112151 and is the recommended substitute for new designs and production applications. Selection rationale is based on the following factors:

• Product Status: The substitute part maintains Active manufacturing status, ensuring long-term component availability and supply chain stability
• Regulatory Compliance: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and safety standards
• Electrical Performance: The substitute part exceeds the original voltage specification (600 V vs. 300 V), providing enhanced margin for circuit protection and reliability
• Mechanical Compatibility: Identical pitch, position count, mounting type, and termination method ensure direct PCB footprint compatibility without design modification
• Thermal Performance: Identical operating temperature range (-40°C ~ 115°C) maintains thermal design margins

The KO1121510000G is suitable for direct replacement in applications where the OSTKO112151 was originally specified.

Frequently Asked Questions (FAQ)

Q: Can the KO1121510000G be used as a direct replacement for the OSTKO112151 without PCB redesign?

A: Yes. Both parts share identical pitch (0.375" / 9.53mm), position count (11), mounting type (Through Hole), and mating orientation (Horizontal with Board). No PCB footprint modification is required.

Q: What is the difference in voltage rating between the two parts?

A: The OSTKO112151 is rated for 300 V, while the KO1121510000G is rated for 600 V. The higher voltage rating of the substitute part provides additional safety margin and does not affect compatibility in applications operating at or below 300 V.

Q: Are the screw torque specifications compatible?

A: The OSTKO112151 specifies 1.0 Nm (8.9 Lb-In) screw torque, while the KO1121510000G specifies 0.62 Nm (5.5 Lb-In). Assembly procedures should follow the torque specification of the substitute part to ensure proper clamp force without over-tightening.

Q: Do both parts accept the same wire gauge range?

A: Yes. Both parts accept wire gauges 10-24 AWG, ensuring compatibility with existing wire preparation and termination procedures.

Q: What is the inventory status of the substitute part?

A: The KO1121510000G has 781 pieces in stock as new original inventory, providing immediate availability for production requirements.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry identical environmental and regulatory classifications. No compliance gaps exist between the original and substitute part.
