OSTV7201151 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The OSTV7201151 is a 20-position terminal block header manufactured by On Shore Technology Inc., featuring female sockets with 0.138" (4.60mm) pitch 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 continuity. The part operates at 300V UL with 8A current capacity and maintains UL94 V-0 flammability compliance across its operating range of -30°C to 105°C.

Substitute Part Grouping Explanation

Substitution eligibility for the OSTV7201151 is determined by strict equivalence across the following critical parameters:

20-position configuration with single-level layout
0.138" (4.60mm) pitch spacing
90° right-angle header orientation
Female socket type with solder termination
Through-hole mounting compatibility
300V UL voltage rating
UL94 V-0 flammability compliance
Phosphor bronze contact material
Thermoplastic housing construction

The substitute part V72011510000G from Amphenol Anytek meets these core mechanical and electrical requirements. Variations in current rating, operating temperature range, and contact finish do not preclude substitution when the application requirements fall within the substitute's specifications.

Engineering Selection Recommendations

The V72011510000G from Amphenol Anytek is an active-status substitute for the obsolete OSTV7201151. Both components maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for equivalent applications.

Selection between these parts depends on application-specific current requirements. The original OSTV7201151 supports 8A per UL specification, while the V72011510000G is rated for 4A. Applications requiring current capacity above 4A must retain the original part number or identify alternative sources. For applications operating at or below 4A, the substitute provides equivalent electrical and mechanical performance with the added benefit of extended operating temperature range (-40°C to 115°C versus -30°C to 105°C).

Both components feature identical mechanical dimensions, pitch spacing, mounting configuration, and contact materials, ensuring direct PCB-level compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can V72011510000G replace OSTV7201151 in all applications?

A: Substitution is valid only when application current requirements do not exceed 4A. The original part supports 8A; the substitute supports 4A. Verify your circuit current draw before substitution.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components share identical pitch (0.138" / 4.60mm), contact tail length (0.134" / 3.40mm), insulation height (0.260" / 6.60mm), and 90° right-angle orientation. No PCB layout modification is required.

Q: Do both parts meet the same compliance standards?

A: Yes. Both OSTV7201151 and V72011510000G are ROHS3 compliant and carry UL94 V-0 flammability ratings. Both operate at 300V UL.

Q: What is the difference in operating temperature range?

A: OSTV7201151 operates from -30°C to 105°C. V72011510000G operates from -40°C to 115°C. The substitute provides a wider operating window, beneficial for extended environmental applications.

Q: Why is the original part listed as obsolete?

A: OSTV7201151 is classified as obsolete by On Shore Technology Inc. The V72011510000G substitute from Amphenol Anytek maintains active product status, ensuring ongoing availability and supply chain continuity.

Q: Are there differences in contact finish?

A: OSTV7201151 does not specify contact mating finish. V72011510000G specifies tin finish. This difference does not affect mechanical or electrical compatibility for standard solder termination applications.
