Parts Availability

Other Parts Discussed in Thread: MSP430FG477, MSP430F4152

I'm interested in a couple parts, the MSP430F4152 and the MSP430FG477, but for these parts and a lot of similar parts are listed as "non-stocked" parts - there's inventory available, but they won't be restocked.  For the MSP430FG477, there's no distributor stock.

I'm new to the MSP430 lineup, so I'm wondering how these parts are purchased?  Should I try to steer clear of non-stocked parts?  Do I need to order 6 or 20 weeks in advance, depending on the chip?  Does TI usually sell these direct?  Thanks!

    Hi,

    I recommend getting some free samples to develop with (before you need more than a few), which can be ordered on the MSP's respective product folder: http://focus.ti.com/docs/prod/folders/print/msp430fg477.html#samples 

    Lead times vary. Also the distributor stock changes often, so I recommend contacting our Product Information Center at support.ti.com

    That's what I'm doing, but my concern is that most of the chips I'm looking at have low or no distributor stock, and the lead times are generally 6 weeks, 20 weeks, or Call to find out.  I can't work with 20 weeks, but I can work with 6 weeks.  I could choose a chip based on its lead time/distributor stock - is that how do most people people deal with this? 

    Are chips with long lead times or zero distributor stock in danger of becoming obsolete?

    As a senior design engineer, I'm increasing very concern with free sample phase with low price, small volume then bang zero stock with lead time 10-30 weeks later with double price tactic, not limited to Microcontroller and DSP device but also affects low power ICs including ADC.

    I getting increasing concern with this kind of tactic which make me think twice recommending any TI product including Burr Brown products. It so serious I have adopted assessment for other non-TI parts unless I have no choice to use TI with risk of delayed production and delivery (with additional cost). During design review they tend to ask why I choose TI parts because they know about TI zero stock issue and they very reluctance to accepts any TI parts. I have been asked to try again with non-TI parts, so it appears a bad reputation is forming around the TI.    

    This mean once the part is selected it stay with our stock system which apply to other project and design with clear policy to re-use approved parts within our BOM because of MOQ volume purchase where all invested components must be used. This mean for long term, it difficult to switch to TI or Burr Brown stuff unless significant proof that TI disposed of this practice.

    Granted they make nice product with state of the art ICs and stuff but zero stock and long lead time became a serious issue for me.

    Richard,

    Thanks for your comments, I really appreciate your participation in E2E and your feedback.

    Though it has been great to see customer demand for TI products surge over the past several months, this unprecedented, unforecasted increase has caused demand to exceed our supply of products in some areas. 

    We are responding as quickly as possible by adding manufacturing personnel and more production capacity, especially in assembly & test for the package types that are in highest demand.  Even so, we have had to adjust product lead times and delivery dates.  With the capacity increases, our goal is to rebalance our supply with demand and reduce lead times as soon as possible. 

    Of course, the exact timing to achieve this balance also depends on future demand trends. If lead times for certain products do not match your production requirements, we can definately work with you to identify alternatives that might work for you in the interim.

    Also, I was a little concerned about your comment regarding pricing, because what you have described is not the way TI does business.   Would it be possible to have someone follow up with you directly to clarify and resolve the issue.

    How temporary is this situation, though?  When will lead times start to decrease?  The lead time for the MCU I'm using in jumped from 7 weeks to 21 weeks, so we purchased all remaining inventory, but it'll be tough to wait almost half a year to restock.
