Parts availability is a bear at the moment. It appears that the MLCC makers got tired of racing to see who could make the least money, and they are discontinuing tons of low profitable parts. I have equivalents for most of my parts designated already, but we are having to reach into alternates for equivalents to get the parts we need.
Hopefully there's nothing too critical about that transistor and you can find a suitable sub. -----Original Message----- From: time-nuts <time-nuts-boun...@lists.febo.com> On Behalf Of John Ackermann N8UR Sent: Monday, June 25, 2018 10:59 AM To: Discussion of precise time and frequency measurement <time-n...@febo.com> Cc: TAPR Office <taproff...@tapr.org> Subject: [time-nuts] TNS-BUF order update To those who pre-ordered TNS-BUF boards: We've had a delay due to parts availability -- a common transistor (PZT3904) is apparently on worldwide back order with lead times quoted of up to a year. Our contract manufacturer has finally found a source, but they will not be delivered until mid-August. That means that TAPR won't receive the boards until the second half of September. If the delay causes you a problem and you'd like to cancel your order, please contact the TAPR office (taproff...@tapr.org) and John will take care of that (though he will be out of town until July 6). Sorry for the inconvenience, but we did not want to risk using a substitute component that might change the performance of the unit.
