Find IC Package Specs: Dimensions, Pitch & More

In summary, the person is looking for a place to easily compare physical specifications for various IC packages, particularly for SMT varieties. They are frustrated with the lack of information provided by online shopping sites and suggest checking the datasheet or using Wikipedia as a resource.

Is there some place online where I can find physical specs (dimensions, pitch, etc) for various IC packages, especially all the jillions of SMT varieties, so I can easily compare them?

I'm doing some shopping on Mouser/Digikey, and I don't have any easy way of knowing what the differences are between things like SOT-108, SOT-337, and SOT-402 (which all look the same in the pictures), or if there even are any significant differences.

That's quite annoying, no? You should be able to flip through to the end of the datasheet for package dimensions (CAD drawing of the IC along with the dimensions). Sometimes, you can even see suggested footprints (those these are really quite rare).

The following page (and some of the ones linked to on the left-hand column) may be of benefit. Keep in mind, different manufacturers often have a nasty habit of not always following each-others specs, so always verify footprints against specific datasheets.

The obligatory Wikipedia / Wikia pages that may be of some benefit:

FAQ: Find IC Package Specs: Dimensions, Pitch & More

What is an IC package?

An IC package is a small, protective casing for an integrated circuit (IC) that contains electrical connections and protects the IC from environmental damage.

What are the dimensions of an IC package?

The dimensions of an IC package can vary depending on the type of package and the specific IC it is designed for. Common dimensions range from a few millimeters to a few centimeters in length, width, and height.

What is pitch in relation to IC packages?

Pitch refers to the distance between the center of one pin on an IC package to the center of the adjacent pin. It is an important measurement for determining the spacing and layout of the pins on an IC package.

How do I find the specs for an IC package?

There are several ways to find the specs for an IC package. You can search the manufacturer's website or datasheet for the specific IC you are interested in, or you can use online databases or tools that provide information on a wide range of IC packages.

Why are IC package specs important?

IC package specs are important because they provide crucial information for designing and using integrated circuits. They can help determine the size and layout of the IC, as well as its electrical and thermal properties, which can affect performance and reliability.
