The Bulk tube quantity is the unit count per tube; no reel or tape carrier, so pick-and-place lines need a tube feeder or manual insertion. It is RoHS non-compliant, meaning the lead finish is tin-lead (SnPb) rather than pure tin — a legacy BOM requirement for assemblies that still specify a leaded solder process or where tin-whisker risk is unacceptable. ## Sourcing and quoting — what to expect No stock-holding claim; the supply posture is per-request sourcing.","metaTitle":"Texas Instruments 4027BDC J-K Flip-Flop, Bulk, Active","metaDescription":"Texas Instruments 4027BDC J-K flip-flop in Bulk package.

The pinout and function are the same, but supply voltage range, switching speed, and input thresholds differ — confirm the BOM's logic levels and timing budget before substituting."},{"question":"Why is 4027BDC RoHS non-compliant?","answer":"The 4027BDC uses a tin-lead (SnPb) lead finish, which is not RoHS-compliant. This is typical of legacy through-hole logic ICs that were designed before the RoHS directive. The part is suitable for assemblies that still specify a leaded solder process or where tin-whisker mitigation is required."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/4027BDC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/4027BDC when reusing this data.
