All manufacturers building products, regardless of their industry, get started by creating a bill of materials (BOM).Because the bill of materials pulls together all sorts of product information, it is common that several disciplines (design and engineering, document control, operations, manufacturing, purchasing, contract manufacturers and more) will consume data contained within the BOM record to get the job done right.
For example, blindly substituting the filter capacitors on a switching regulator, even if the substitute has the same rated capacitance and voltage, can lead to unstable operation and even boards catching fire.Of course, there are times when one is truly insensitive to the manufacturer, in which case I would mark on the BOM “any/open” for the AVL (particularly true for things like pull-up resistors).

A manufacturer is not a distributor (i.e., Digikey, Mouser, Avnet); a manufacturer is the actual company that makes the part. The extra characters are very important, because small variations can lead to big problems, such as quoting and ordering the wrong packaged device (and subsequently being stuck with a reel of unusable parts), or subtle reliability problems. For power inductors, core composition, DCR, saturation, temperature rise current, are the basic parameters, but there is also no standard for casing like there is for resistors and capacitors.
Furthermore, important parameters such as shielding and potting, which can have material impacts on the performance of a circuit, are often implicit in a part number; hence, it’s best to simply fully specify the inductor and not leave it any/open. It’s a fundamental set of data, used throughout the process. In fact, I encountered a problem once due to a mistaken substitution of a “VHC” for the “VHCT” logic family part.

This lecture provides the framework for how to develop a technology roadmap that fits your needs.
