I need to order a 32 pin LQFP chip and replace it with another 32 pin TQFP chip so is it ok to replace it or it won't be compatible?
The chip is an STM8S003K3 MCU

\$\begingroup\$ What're the package dimensions? Does the datasheet recommended footprint line up well enough? \$\endgroup\$– HearthCommented Aug 12, 2023 at 15:17

If you refer to the datasheet, it does not appear to be offered by ST in a TQFP package, only 0.8mm pitch LQFP32 in 32-pins.
So whatever it is that you are potentially ordering is either not ST or there is an error of some kind. I suggest you get to the bottom of it before placing an order.

\$\begingroup\$ I guess so, but in general is it ok to use the LQFP instead of TQFP package? (I edited the question so we can speak in gerneral) \$\endgroup\$ Commented Aug 12, 2023 at 15:12

2\$\begingroup\$ You need to look at the drawing of the package in the datasheet and see if it is compatible. If only the height is different it could well be compatible. If the pitch or body size is different.. \$\endgroup\$ Commented Aug 12, 2023 at 15:25

\$\begingroup\$ Thanks mate, I had checked it and yes it is compatible. \$\endgroup\$ Commented Aug 12, 2023 at 15:33
