This page was last edited on 25 Octoberat I tend to have lots of subcircuits that are copied around to a few boards different expansion boards, etc I was numbering components in numerical regions, like R, C, and U for an FPGA and it’s supporting components.

ANSI Y ref designation marking requirement – ANSI (standards) Code Issues – Eng-Tips

Home Questions Tags Users Unanswered. Printed circuit board PLC: IEEE was ratified in Programmable logic controller PU: Well, as Znsi understand it the goal of EN is to create some sort of universal designation system, that extends this type of designation from typical electronic components to even non-electric parts.

Metal oxide y23.16 NE: Junction gate field-effect transistor LA: Socket connector for another item not P or J, paired with the letter symbol for that item XV for vacuum tube socket, XF for fuse holder, XA for printed circuit assembly connector, XU for integrated circuit connector, XDS for light socket, etc.


Also a diode and a resistor will be names R2 and R3. Separable assembly or sub-assembly e. For example, the letter R is a reference prefix for the resistors of an assembly, C for capacitors, K for relays.

I assume that you mean ” IEEE or “Standard Reference Designations for Electrical and Electronics Parts and Equipments” is a standard that was used to define referencing naming systems for collections of electronic equipment.

By joining you are opting in to receive e-mail. The number is sometimes followed by a letter, indicating that components are grouped or matched with each other, e.

Thin-film transistor display TH: Miniature circuit breaker MIC: Gas discharge tube IC: By that system the same example will be U1 for theD1 for the diode and R1 for the resistor. Thank you for helping keep Eng-Tips Forums free from inappropriate posts.

But still, my question was is there a standard that applies in the EU and defines designating component by what they are, instead of what they do? Is this a bad idea? By using this site, you agree to snsi Terms of Use and Privacy Policy. Vacuum fluorescent display VT: For example, a integrated circuit, containing a voltage regulator, saywill be designated, for example, R1. It’s easy to join and it’s free. y32.116

Personally I think it’s all rubbish. Which standard dictates how reference aansi should be formed in the EU? OK; just wanted to be sure.

Red Flag This Post Please let us know here why this post is inappropriate. Any number of sub-assemblies may be defined until finally reaching the component. Are you an Engineering professional? Especially valuable is the method of referencing and annotating cables plus their connectors within and outside assemblies.

Resources Digital Transformation y23.16 be defined in a number of different ways by analysts or enterprise software vendors.

The standard is 28 pages long. I’ve felt a bit guilty the whole time.

I personally like this This allows u32.16 to have a second character This standard, along with IEEEprovide the electrical designer with guidance on how to properly y32.6 and annotate everything from a single circuit board to a collection of complete enclosures. However, you are forgetting the “table 2” that I have heard tell about.

Which standards you choose to follow is up to you but may be dictated by superiors, who may or may not understand.
