OSTVE103151 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The OSTVE103151 is a 10-position terminal block header manufactured by On Shore Technology Inc., designed for through-hole solder mounting applications. This component features male pins with 4-side shrouding, a 0.150" (3.81mm) pitch, and right-angle orientation. The part is currently active in production and widely used in industrial control, automation, and power distribution applications where reliable electrical connections are required.

Substitute parts are identified when equivalent electrical and mechanical specifications are met, enabling procurement flexibility, inventory optimization, and supply chain continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the OSTVE103151 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility: Voltage rating (300 V UL minimum), current capacity (8 A UL minimum), and contact material properties
Mechanical Compatibility: 10-position count, 0.150" (3.81mm) pitch, right-angle orientation, male pin configuration, and 4-side shrouding
Mounting and Termination: Through-hole solder termination only
Environmental and Compliance: UL94 V-0 flammability rating, ROHS3 compliance, and MSL 1 rating

The substitute part 1-284513-0 (TE Connectivity AMP Connectors, Buchanan series) meets all these criteria and is classified as a manufacturer-recommended equivalent.

Engineering Selection Recommendations

The 1-284513-0 terminal block header from TE Connectivity is a valid substitute for the OSTVE103151 based on electrical and mechanical equivalence. Both components are active products with ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial applications.

The substitute part demonstrates enhanced performance specifications in current capacity (11 A versus 8 A) and operating temperature range (-40°C ~ 110°C versus -30°C ~ 105°C), providing additional design margin without compromising compatibility. Contact material differences (phosphor bronze versus brass) and housing material variations (polyamide versus thermoplastic) do not affect functional interchangeability within the specified electrical and environmental parameters.

Selection between these parts should be based on availability, lead time, cost considerations, and established supplier relationships, as both meet the technical requirements for equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can the 1-284513-0 be used as a direct replacement for the OSTVE103151 in existing designs?

A: Yes. Both components share identical electrical ratings (300 V, 8 A minimum), mechanical configuration (10 positions, 0.150" pitch, right-angle, male pins, 4-side shrouding), and termination method (through-hole solder). PCB footprints and mounting hole patterns are compatible.

Q: What are the key differences between these two parts?

A: The primary differences are contact material (brass versus phosphor bronze), housing material (thermoplastic versus polyamide), and enhanced performance specifications in the substitute part. The 1-284513-0 supports higher current (11 A) and wider operating temperature range (-40°C ~ 110°C). These differences do not affect interchangeability for applications within the OSTVE103151 specifications.

Q: Are both parts compliant with industry standards?

A: Yes. Both the OSTVE103151 and 1-284513-0 are ROHS3 compliant, carry UL94 V-0 flammability ratings, and have MSL 1 moisture sensitivity levels. Both are suitable for regulated industrial and commercial applications.

Q: Does pitch compatibility guarantee mechanical fit?

A: Pitch equivalence (0.150" / 3.81mm) combined with identical position count, shrouding configuration, and right-angle orientation ensures mechanical compatibility. Both parts are designed for standard 0.150" pitch PCB layouts and will mount without modification.

Q: Can these parts be mixed in the same assembly?

A: Yes. Since both parts meet identical electrical and mechanical specifications, they can be used interchangeably within the same assembly or design revision without functional impact.
