So although Aliexpress etc have MC3446D's quite cheap, they do show a picture of a Surface-Mount one - So not suitable. And these are TI's package details that are not in their datasheet, but found from: https://www.ti.com/packaging/docs/se...tipackages.tsp D (R-PDSO-G16) Plastic Small Outline Package: https://www.ti.com/lit/ml/mpds178g/mpds178g.pdf J (R-GDIP-T**) Ceramic Dual In-Line Package: https://www.ti.com/lit/ml/mgdi003/mgdi003.pdf N (R-PDIP-T**) Plastic Dual In-Line Package: https://www.ti.com/lit/ml/mpdi002c/mpdi002c.pdf So shows that MC3446N or MC3446J would also be OK for original MC3446P |

I agree that 'D' almost always means surface-mount, where 'N' almost always means DIP, although confusingly DIP ICs may not always end in 'N'.

I presume we are still agreed that MC3446AP is an acceptable substitute for MC3446N? Otherwise we may be causing Colin some anxiety here in our desire to be meticulous.
