OSTEH232160 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTEH232160 is a 23-position terminal block plug manufactured by On Shore Technology Inc., designed for unshrouded headers with 0.138" (3.50mm) pitch spacing. This component features screw-leaf spring termination with wire guard protection and is rated for 150V UL operation across a temperature range of -40°C to 115°C. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSTEH232160 is determined by strict equivalence across the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 23 positions at 0.138" (3.50mm) pitch to ensure mechanical compatibility with existing header connectors
• Connector Type: Both must be plugs designed for unshrouded headers with identical mounting orientation (free hanging, in-line)
• Termination Method: Screw-leaf spring termination with wire guard protection is required for functional equivalence
• Wire Gauge Compatibility: 16-28 AWG wire acceptance range must be maintained
• Operating Temperature Range: -40°C to 115°C minimum specification required
• Regulatory Compliance: ROHS3 compliance and UL94 V-0 flammability rating are mandatory

The substitute part TH2321500000G by Amphenol Anytek meets all critical substitution criteria while offering enhanced electrical specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

The OSTEH232160 is classified as obsolete, necessitating transition to active alternatives for new procurement and long-term system support. The TH2321500000G substitute part maintains full mechanical and electrical compatibility across all critical parameters while providing enhanced voltage rating (300V versus 150V) and active product status from Amphenol Anytek.

Both parts satisfy ROHS3 compliance and UL94 V-0 flammability requirements. The substitute part's higher voltage specification provides additional design margin without compromising any functional requirements of the original component. Active product status ensures continued availability, technical support, and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can TH2321500000G directly replace OSTEH232160 in existing applications?

A: Yes. Both parts maintain identical position count (23), pitch spacing (0.138"/3.50mm), termination method (screw-leaf spring with wire guard), wire gauge range (16-28 AWG), and operating temperature range (-40°C to 115°C). Mechanical and electrical compatibility is confirmed.

Q: What is the significance of the voltage rating difference (150V vs 300V)?

A: The substitute part's 300V rating exceeds the original 150V specification. This provides additional design margin and does not create incompatibility. Applications designed for 150V operation remain fully compatible with the 300V-rated substitute.

Q: Does the plug wire entry orientation affect substitution?

A: The OSTEH232160 does not specify plug wire entry orientation. The TH2321500000G specifies 90° wire entry. This represents an enhancement in design specification and does not prevent substitution in applications where the original part was used.

Q: Are there packaging or inventory considerations?

A: The OSTEH232160 is available in limited inventory (882 pcs). The TH2321500000G is actively manufactured with current inventory (637 pcs). For new designs and long-term applications, the active substitute part is recommended to ensure supply continuity.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both parts are ROHS3 compliant and carry UL94 V-0 flammability ratings. Regulatory compliance is equivalent across both components.
