OSTV718A151 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The OSTV718A151 is an 18-position terminal block header manufactured by On Shore Technology Inc., featuring female sockets with 0.295" (7.50mm) pitch spacing and 90° right-angle orientation for through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning. The part operates at 10 A (UL) and 300 V (UL) with UL94 V-0 flammability rating and ROHS3 compliance.

Substitute Part Grouping Explanation

Substitution eligibility for the OSTV718A151 is determined by the following critical parameters:

Position Count & Configuration: 18 positions, single level
Connector Type: Header with female sockets
Orientation: 90° right-angle through-hole mounting
Electrical Performance: 10 A (UL) and 300 V (UL) minimum requirements
Compliance: UL94 V-0 flammability, ROHS3, and REACH unaffected status
Contact & Housing Materials: Phosphor bronze contacts with thermoplastic housing
Termination: Solder-based connection

The substitute part V71871510000G from Amphenol Anytek meets these core functional requirements. The primary difference is pitch spacing (0.197" / 5.00mm versus 0.295" / 7.50mm), which represents a mechanical redesign consideration rather than an electrical incompatibility. Both parts maintain identical position count, electrical ratings, compliance certifications, and material specifications.

Engineering Selection Recommendations

The V71871510000G substitute part is qualified for replacement based on the following engineering criteria:

Compliance & Certification Alignment: Both parts maintain identical UL94 V-0 flammability ratings, ROHS3 compliance, and REACH unaffected status, ensuring regulatory continuity in applications subject to these standards.

Electrical Performance: Identical current (10 A UL) and voltage (300 V UL) ratings confirm electrical compatibility for the intended application domain.

Product Status Advantage: The substitute part carries active product status, ensuring long-term availability and supply chain stability compared to the obsolete OSTV718A151.

Operating Temperature Range: The V71871510000G provides an extended operating temperature range (-40°C ~ 115°C) compared to the main part (-30°C ~ 105°C), offering improved thermal margin in demanding environments.

Mechanical Redesign Consideration: The pitch reduction from 7.50mm to 5.00mm requires PCB layout modification. This is a design-level change, not an electrical incompatibility, and must be evaluated against board space constraints and connector footprint requirements.

Frequently Asked Questions (FAQ)

Q: Can V71871510000G directly replace OSTV718A151 without PCB modification?

A: No. The pitch spacing differs (5.00mm versus 7.50mm), requiring PCB footprint redesign. The connector mounting holes and trace routing must be recalculated for the substitute part.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both parts operate at 10 A (UL) and 300 V (UL) with identical contact material (phosphor bronze) and housing material (thermoplastic), ensuring electrical performance equivalence.

Q: Does the substitute part meet the same compliance requirements?

A: Yes. V71871510000G maintains UL94 V-0 flammability rating, ROHS3 compliance, and REACH unaffected status, matching the regulatory profile of OSTV718A151.

Q: What is the significance of the extended operating temperature range in the substitute?

A: The V71871510000G operates from -40°C to 115°C compared to -30°C to 105°C for the main part. This provides additional thermal margin but does not affect compatibility if the original application operated within the narrower range.

Q: Is the substitute part currently available?

A: Yes. V71871510000G carries active product status with 800 pcs in stock, providing supply continuity for the obsolete OSTV718A151.

Q: What packaging format is the substitute supplied in?

A: V71871510000G is supplied in bulk packaging, compared to the main part's unspecified packaging format.
