Mike, don't take this as an insult, but have you ever worked in an industrial setting? When we sent manufacturers specs they were supposed to follow those specs to the letter, not deviate from the specs when they felt the need.
Again, I bring up something as simple as a Bud bottle (I worked in the glass industry for a few years before settling into the chemical manufacturing world). Deviate just a touch with a bottle of Bud and you lose the contract, at worst, or are put into the lower echelon of suppliers. Specs are specs. Defined by engineers and should produce identical devices or items.
Go buy a part from your local NAPA store. You'll notice it is identical to the original part that is on your car. Is it made by GM? No, but it's made to GM's specs.
No problem Rich. No offense taken.
As a matter of fact, I work in such an industry right now. Most of what we design and implement are based on using specific components and meeting certain performance criteria (in my case fluid mechanical systems). As to the physical layout of those components, that we determine to meet the criteria specified by the customer. In certain cases from one ship to another (we build ships for the Navy) components unrelated to my piping system require changing the geometry of my system while maintaining the specified criteria.
IOW, we use the components specified, using the materials specified, and meet the performance criteria specified and still have a different physical arrangement from ship to ship. This same premise applies at scale ranging from large piping systems to electronic components. Using the requested parts and meeting the specified performance in a different arrangement. It's done all the time in engineering design.
In the case of a Bud bottle, a deviation from specs is a deviation from brand recognition.
I can’t tell you the number of times I’ve gotten a replacement part that the dealer such as Chevy and from a store such as NAPA and in each case the part was different from the original, but
was considered equivalent to OEM...I’m just sayin’
