Do you want the oblong pad version? I'll build it for you.

Simple 5-minute task in FP Designer.

As i understand, constrict + stretch the pads is undesirable.

For example, footprint on page 15:

Then you make the "D" and "D1" dimensions different.

You must bend the leads.

You decide the dimension value that you want to bend 2 leads.

I am sorry, the right datasheet is here:

http://ww1.microchip.com/downloads/en/DeviceDoc/21374D.pdf

see page 11.

The Pin Pitch is 2.54 mm (100 mil).

The pads should not overlap.

I try to create the footprint for

https://www.onsemi.com/pub/Collateral/TIP50-D.pdf

The datasheet doesn't content any recommendation.

If i create it in calculator than the pads cover each other

partially. I want to redraw the pad dimension manually.

Is there any general recommendations to create the elongate pad?
