Enpirion Depreciation Impact

Summary

The Enpirion product line has been the "go to" for our DC/DC converter needs for many years. It was first used in the RCE generation 3 development 10+ years ago because of its low PCB footprint area.  After the RCE development, we have been using it for other TID-ID related designs (LCLS-II, LCLS DAQ, LDMX, LSST, etc).

Original Enpirion was originally owned by Altera.  Later Altera was bought by Intel.  In September 2021, Intel announced that it will depreciate their entire "Enpirion" product line with no replacement OPN.  The last time to buy was March 18, 2022.

In September 2021, we did a survey of all TID-ID PCB BOMs to identify which ones were using Enpirion product line.  After identifying the PCB designs using this DC/DC converter, we contacted all the PCB designers to inform them about the depreciation.  We also asked the PCB designers the following questions:

• Is this an "active" design that they plan to make more of?
• If not, is this an "active" design that they do NOT plan to make more of?
• If not, is this a non-active design?

From that questionnaire we have create tables for those 3 category types below.

Active projects that we WILL build more boards of

• These are active projects that we need to get the PCB design updated to not use Enpirion
• Requires new schematics and respin of layout

Active Project that we are MAY build more boards of (NEED Enpirion spares)

• These are active projects that we do NOT plan on making more of.  Need to buy enough Enpirion spares before March 18, 2022 for "just in case".

Inactive Projects that we are NOT planning to build more boards of

Recommended Part Replacements (not drop-in replacements)
