Substitute Part Grouping Explanation

Substitution eligibility for the OSTV7097250 is determined by strict equivalence across the following critical parameters:

Position Count & Pitch: 9 positions at 0.197" (5.00mm) spacing
Electrical Ratings: 10 A (UL) and 300 V (UL) minimum
Physical Configuration: Vertical orientation, through-hole mounting, solder termination
Mechanical Dimensions: Contact tail length 0.138" (3.50mm) and insulation height 0.748" (19.00mm)
Material Specifications: Phosphor bronze contacts, thermoplastic housing, UL94 V-0 flammability rating
Functional Features: Mating flange and retention latches

The substitute part V70972500000G, manufactured by Amphenol Anytek, meets all these critical parameters. This part maintains identical electrical and mechanical specifications while offering improved product status (active vs. obsolete) and extended operating temperature range (-40°C to 115°C vs. -30°C to 105°C).

Engineering Selection Recommendations

V70972500000G is a direct functional equivalent to OSTV7097250 for applications requiring a 9-position, 5.00mm pitch terminal block header with vertical through-hole solder termination. Both parts maintain identical electrical performance (10 A UL, 300 V UL) and mechanical compatibility. The substitute part offers the advantage of active product status, ensuring long-term availability and supply chain continuity. Both components satisfy ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The extended operating temperature range of V70972500000G (-40°C to 115°C) provides additional thermal margin compared to the original part specification (-30°C to 105°C).

Frequently Asked Questions (FAQ)

Q: Can V70972500000G be used as a direct replacement for OSTV7097250 in existing designs?

A: Yes. Both parts share identical electrical ratings (10 A UL, 300 V UL), mechanical dimensions (9 positions, 5.00mm pitch, 0.138" contact tail length, 0.748" insulation height), termination method (solder), and mounting configuration (vertical through-hole). Physical and electrical compatibility is confirmed.

Q: What is the primary reason for substitution?

A: OSTV7097250 is classified as obsolete. V70972500000G, manufactured by Amphenol Anytek, is an active product with confirmed inventory availability and ongoing manufacturer support.

Q: Are there differences in contact finish between these parts?

A: OSTV7097250 does not specify contact mating finish. V70972500000G specifies tin contact mating finish, which is standard for phosphor bronze terminal block contacts and does not affect electrical or mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both OSTV7097250 and V70972500000G are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the operating temperature difference between these parts?

A: OSTV7097250 operates from -30°C to 105°C. V70972500000G operates from -40°C to 115°C, providing a wider thermal operating window. For applications within the original part's temperature range, both parts perform identically.

Q: Are the packaging formats compatible?

A: OSTV7097250 packaging is not specified. V70972500000G is supplied in bulk packaging. Confirm packaging requirements with your procurement process.
