Engineering Selection Recommendations

The BAV99W/MIX is classified as an obsolete product. Both substitute parts, BAV99W,115 and BAV99W,135, are active products with identical electrical specifications and package configurations.

For new designs and production continuity:

BAV99W,115 and BAV99W,135 are direct functional equivalents suitable for replacing the BAV99W/MIX. Both parts maintain full compliance with automotive-grade requirements and AEC-Q101 qualification. The substitutes are available in Cut Tape (CT) and Digi-Reel® packaging formats, supporting both prototype and high-volume production requirements.

Selection between BAV99W,115 and BAV99W,135 is determined by packaging and supply chain requirements, as both parts are electrically and mechanically identical. Inventory availability for both substitutes is substantially higher than the obsolete BAV99W/MIX, ensuring long-term supply security.
