OSTV7151250 Terminal Block Header - Equivalent & Substitute Parts
Part Overview
The OSTV7151250 is a 15-position terminal block header manufactured by On Shore Technology Inc., designed for vertical through-hole mounting with 4.6mm pitch female sockets. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing production and maintenance applications. The part operates at 300V UL with 8A current capacity and maintains UL94 V-0 flammability compliance across an operating temperature range of -30°C to 105°C.

Substitute Part Grouping Explanation
Substitution eligibility for the OSTV7151250 is determined by strict alignment of the following critical parameters:
- 15-position configuration with single level
- 0.138" (4.60mm) pitch spacing
- Vertical through-hole mounting orientation
- Female socket type with solder termination
- 300V UL voltage rating
- UL94 V-0 flammability compliance
- Phosphor bronze contact material
- Thermoplastic housing construction
The substitute part V71512500000G, manufactured by Amphenol Anytek, satisfies these core electrical and mechanical requirements. However, variations exist in current rating (4A versus 8A), operating temperature range (-40°C to 115°C versus -30°C to 105°C), and product status (active versus obsolete).

Engineering Selection Recommendations
The V71512500000G substitute part maintains mechanical and electrical compatibility with the OSTV7151250 across all critical interface dimensions and voltage specifications. Both parts carry ROHS3 compliance and UL94 V-0 flammability certification, satisfying regulatory requirements for equivalent component selection.
The primary consideration for substitution is the current rating differential: the substitute part is rated at 4A UL versus the original 8A UL specification. Applications operating at or below 4A current levels are suitable for direct substitution. Applications requiring the full 8A capacity of the original part require current-limited circuit design or alternative component selection.
The substitute part's extended operating temperature range (-40°C to 115°C) provides broader environmental coverage compared to the original specification (-30°C to 105°C), presenting no thermal compatibility constraints for standard industrial applications.
Frequently Asked Questions (FAQ)
Q: Can V71512500000G be used as a direct replacement for OSTV7151250?
A: Mechanical and electrical interface compatibility is confirmed. The substitute part accommodates the same 15-position, 4.6mm pitch configuration with identical through-hole mounting and solder termination. Current rating differences must be evaluated against circuit requirements.
Q: What is the significance of the 4A versus 8A current rating difference?
A: The substitute part V71512500000G carries a maximum UL current rating of 4A, compared to 8A for the original OSTV7151250. Circuit designs operating within 4A limits are fully compatible. Designs requiring 8A capacity require alternative solutions or current management modifications.
Q: Are there compliance or certification differences between the parts?
A: Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification. No regulatory compliance gaps exist between the original and substitute components.
Q: How do the operating temperature ranges compare?
A: The substitute part operates across -40°C to 115°C, extending below and above the original -30°C to 105°C range. This broader specification presents no compatibility issues for standard industrial temperature environments.
Q: What packaging format is available for the substitute part?
A: The V71512500000G is supplied in bulk packaging, differing from the original part's packaging specification.
