Substitute Part Grouping Explanation

Substitution eligibility for the OSTV7087251 is determined by strict equivalence across the following critical parameters:

8-position configuration with single level
5.00mm pitch spacing
90° right-angle header orientation
Female socket type
Solder termination for through-hole PCB mounting
10A current capacity at 300V voltage rating
Phosphor bronze contact material

Engineering Selection Recommendations

The V70872510000G from Amphenol Anytek is a direct functional equivalent to the obsolete OSTV7087251. Both components maintain identical electrical ratings (10A at 300V), mechanical configuration (8-position, 5.00mm pitch, 90° right-angle), and material specifications (phosphor bronze contacts, thermoplastic UL94 V-0 housing).

The V70872510000G offers an extended operating temperature range (-40°C to 115°C versus -30°C to 105°C) and active product status, ensuring ongoing availability and supply chain support. Both parts carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

For applications currently using the OSTV7087251, direct substitution with V70872510000G requires no circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can V70872510000G replace OSTV7087251 in existing designs?

A: Yes. Both components share identical electrical ratings, pitch spacing, mounting type, and contact configuration. PCB footprints and connector mating interfaces are compatible.

Q: What is the difference in insulation height between these parts?

A: The OSTV7087251 has an insulation height of 0.339" (8.61mm), while the V70872510000G measures 0.425" (10.80mm). This difference does not affect electrical function but may impact board-to-board spacing in constrained layouts. Verify clearance in your specific application.

Q: Are there temperature rating differences?

A: The V70872510000G operates across -40°C to 115°C, providing a wider range than the OSTV7087251 (-30°C to 105°C). This extended range supports applications in more extreme thermal environments without performance degradation.

Q: Does the contact mating finish differ?

A: The OSTV7087251 does not specify a contact mating finish, while the V70872510000G uses tin plating. Tin finish provides standard corrosion resistance and is compatible with standard solder reflow processes.

Q: What packaging is available for the substitute part?

A: The V70872510000G is supplied in bulk packaging, suitable for production assembly environments.
