FAQ
Where to buy BC817-40?
You can request BC817-40 from SJ Chip via the RFQ form on this page or the site-wide RFQ. We confirm manufacturer (NXP Semiconductors), package, quantity, and lead time on the quotation.
Is BC817-40 available?
Listed inventory shows 200,000 pcs. Lot, date code, and shippable quantity are confirmed on RFQ — treat the listing as availability to quote, not a guaranteed cart ship.
What is the package of BC817-40?
The sourcing listing shows package SOT-23. Always verify body size, pitch, and land pattern against the NXP Semiconductors datasheet before PCB layout.
What are alternatives to BC817-40?
Potential alternatives include BC817-40,215, BC817-40W,135, BC817 215 and other same-series or same-package listings — all require datasheet and pinout checks. These are similar stock for evaluation, not automatic drop-in replacements.
