Vishay CNY17
CNY17 variants from Vishay
CNY17 Overview
What changes between part numbers, and what to check before you lock the BOM — BJTs.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 7 distinct suffix patternsExamples: 1X007T, 3X007, 3X007T, 3X009T, 3X017T (+2 more). Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- BJTs — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained

How to Choose the Right CNY17 BJTs
Match the footprint first
Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.
Electrical headroom
Compare voltage and current columns in the variant table. For CNY17, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "CNY17" — include the full suffix (e.g. 1X007T, 3X007, 3X007T). RFQ with reel/tube preference and required date code.
