Substitute Part Grouping Explanation

Substitution of the OSTV7197151 is determined by strict equivalence across the following critical parameters:

Position Count & Pitch: 19 positions at 0.197" (5.00mm) spacing
Connector Type & Orientation: Female socket header in 90° right-angle configuration
Electrical Ratings: 10 A (UL) and 300 V (UL) minimum
Termination & Mounting: Solder termination with through-hole mounting
Material & Compliance: Phosphor bronze contacts, thermoplastic housing, UL94 V-0 flammability, RoHS3 compliance

The substitute part V71971510000G (Amphenol Anytek) meets all these criteria with identical mechanical and electrical specifications, differing only in product status (active vs. obsolete) and extended operating temperature range.

Engineering Selection Recommendations

The V71971510000G substitute part is electrically and mechanically equivalent to the OSTV7197151 across all critical parameters. Both components maintain identical pitch, position count, electrical ratings, and flammability compliance. The substitute offers the advantage of active product status with extended operating temperature range (-40°C ~ 115°C vs. -30°C ~ 105°C), providing greater thermal margin for demanding applications. Both parts carry full RoHS3 and REACH compliance certifications with identical export classifications (EAR99, HTSUS 8536.69.4040). Selection between these parts should be based on procurement availability and thermal operating requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can V71971510000G be used as a direct replacement for OSTV7197151?

A: Yes. Both parts share identical mechanical dimensions, pitch spacing (5.00mm), position count (19), electrical ratings (10 A / 300 V UL), and termination method (solder through-hole). The parts are mechanically and electrically interchangeable.

Q: What is the primary difference between these two parts?

A: The OSTV7197151 is obsolete, while V71971510000G is an active product. Additionally, V71971510000G offers an extended operating temperature range (-40°C ~ 115°C) compared to the original part (-30°C ~ 105°C).

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical compliance status: RoHS3 compliant, REACH unaffected, UL94 V-0 flammability rating, and EAR99 export classification.

Q: Does the extended temperature range of V71971510000G affect PCB layout or design considerations?

A: No. The extended temperature capability does not alter mechanical footprint, pitch, or mounting requirements. PCB layout remains identical.

Q: What is the contact material composition for both parts?

A: Both parts use phosphor bronze contacts with tin mating finish (where specified), housed in thermoplastic material with retention latches.

Q: Are moisture sensitivity levels the same?

A: Yes. Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
