OSTEH032160 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTEH032160 is a 3-position terminal block plug manufactured by On Shore Technology Inc., designed for unshrouded headers with 0.138" (4.60mm) pitch spacing. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning. The part features screw-leaf spring termination with wire guard protection, suitable for applications requiring secure wire connections in the -40°C to 115°C operating range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTEH032160 is determined by strict alignment of the following critical parameters:

• Mechanical Compatibility: Number of positions (3), pitch spacing (0.138" / 4.60mm), and mounting type (free hanging in-line) must be identical
• Electrical Specifications: Wire gauge range (16-28 AWG) and operating temperature range (-40°C ~ 115°C) must be maintained or exceeded
• Termination Method: Screw-leaf spring with wire guard termination style must be preserved
• Regulatory Compliance: RoHS3 compliance and UL94 V-0 flammability rating required

The substitute part TH0321500000G (Amphenol Anytek) meets all critical mechanical and electrical parameters while maintaining regulatory compliance. This part is classified as active status, providing long-term availability for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The TH0321500000G from Amphenol Anytek is the qualified substitute for the obsolete OSTEH032160. Selection is based on:

• Mechanical Equivalence: Identical pitch, position count, and mounting configuration ensure direct mechanical compatibility with existing unshrouded header connectors
• Electrical Sufficiency: The substitute part exceeds the original voltage specification (300 V vs. 150 V) while maintaining identical wire gauge and temperature operating ranges
• Regulatory Alignment: Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, satisfying compliance requirements
• Availability: The substitute part holds active product status with documented inventory, ensuring procurement viability for new designs and legacy system support

Frequently Asked Questions (FAQ)

Q: Can TH0321500000G be used as a direct replacement for OSTEH032160?

A: Yes. Both parts share identical mechanical specifications (3 positions, 4.60mm pitch, free-hanging in-line mounting) and termination method (screw-leaf spring with wire guard). Wire gauge range and operating temperature are identical. The substitute part exceeds the original voltage rating, providing additional margin.

Q: What are the key differences between these parts?

A: The primary differences are manufacturer (On Shore Technology vs. Amphenol Anytek), product status (obsolete vs. active), and voltage rating (150 V vs. 300 V). Contact material differs (brass vs. phosphor bronze) and housing material differs (brass vs. thermoplastic), but these do not affect functional compatibility for the specified application parameters.

Q: Are there any packaging considerations?

A: The OSTEH032160 packaging specification is not provided in the available data. The TH0321500000G is supplied in bulk packaging. Confirm packaging requirements with your procurement specification before ordering.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability certification. Both are classified under ECCN EAR99 and HTSUS 8536.90.4000.

Q: What wire gauges are supported?

A: Both parts support 16-28 AWG wire gauge range with 5-6mm wire strip length. Screw torque specifications differ slightly (0.12 Nm for OSTEH032160 vs. 0.2 Nm for TH0321500000G), reflecting design differences in the substitute part.
