Documenting parts

At AISLER you can easily document your parts. This can go in two ways:

  • Smart Match for Resistors and Capacitors
  • Specifying by MPN

Not only will we be able to provide you with a great quote for providing parts, but also you will get all available datasheets directly along with it. That means the moment you have documented your part, you’ll have one place to look for all datasheets.

Using Smart Match

Smart Match is our simple tool to easily specify SMD capacitors and resistors, if you do not need a very specific component. On checkout, we choose a fitting component for you. Using Smart Match is similar to assigning a specific componenent. Navigate to the project’s Parts tab and click Assign after selecting one or multiple component in the list. Then enter your specification, e.g., 10µF 10V for a 10µF capacitor with a 10V voltage rating. We then ask you confirm the requirement we extracted from your stated specifications. Note that we default to a 0603 SMD package. If you require a different package just add it as an additional parameter, e.g. 10µF 10V 0805 for a capacitor with a 0805 SMD package.

Important: Since specifications can be ambiguous, it is currently only available for components with designators starting with a R or C. Furthermore, Smart Match is not available for manually documented parts. So use the native upload of your PCB design tool.

Hint: We import the list of parts from your uploaded design file. If you want to save time, state the specifications using the design tool so we can pick them up. As soon as you hit assign on the project’s Parts tab, we run a quick search and you can quickly confirm the Smart Match. Check our documentation for your PCB design tool on how to benefit from it.

Smart Match

Parameters for Resistors

Parameter Example
Resistance 10k
Tolerance 1%
Power 0.1W
Package 0402

In practice, you could hence specify:

  • 10k
  • 10k 1%
  • 10k 0402 5% 0.1W

Please note: The less parameters you specify, the easier it will be for us to provide you with a suitable resistor.

Parameters for Capacitors

Parameter Example
Capacitance 22uF
Dielectric X7R
Voltage rating 16V
Package 1206

In practice, you could hence specify:

  • 22uF
  • 22uF X7R
  • 22uF 16V N0P
  • 22uF 10% 50V 1206

Please note: The less parameters you specify, the easier it will be for us to provide you with a suitable resistor.

Specifying by MPN

If you want to document parts other than Capacitors or Resistors (ICs, Diodes, LEDs, etc) or you cannot find a suitable Smart Match then you can also specify the direct part.

This works multiple ways:

  • The manufacturer’s MPN
  • AISLER’s part id
  • Digikey’s SKUs
  • Mouser SKUs
  • Farnell SKUs


Unfortunately, I can’t manually add parts to my project. I don’t see where or how. How do I do this? I use sprint layout as a designer.

Thanks very much

same problem here…I dont get how to add components manually.

My board is exported from Fusion360 and after import in your webinterface there are no components detected automatically.

I am afraid @mmarkus we currently do not support Sprint Layout for assembly at all.

@p-jauer-mecon-de Please contact us via our support form and we will handle this for you.

Thanks for your feedback @fcordes. Indeed, you should be able to assign parts by Mouser SKU. We are aware of an issue with the part search so that it takes longer than usual. We are actively working on making it faster than every. I am sorry for the inconvenience. I will let you know when everything is back working as expected.

Do you have any tips for SMD electrolytic capacitors and how to specify them? I’ve had trouble matching anything just based on requirements and adding dimensions don’t seem to help much. Is the best way to find a part number or similar type of ID?

If I understood you correctly you tried our Smart Match feature for electrolytic capacitors?
We currently dont support them for smart match, but you can assign a MPN e.g part number.

When looking for a specific capacitor I highly recommend to select one from Würth, Pansonic, Vishay, Taiyo Yuden or Kemet as those offer great quality components.

Okay, I’ll try using a MPN.
Even when manually searching and specifying, for example 5x5.4, the dimensions are not always in the part description so it’s difficult to know if it’s an appropriate part. There’s not always datasheet available either. But using MPN sounds like a good solution.
