Problems using PTH components instead of SMD?

I am making a stm32f411ce board and I want make sure everything works because it's very expensive to order a pcb in my country. I want to use components like Hc-49 8mhz crystal(and dt-38 32.768khz) oscillators with ceramic PTH capacitors, the only smd parts will be the MCU and micro usb and maybe an ams1117 regulator, will I have some issue? is there anything different I have to do?

    Hello,

    I don't see why it wouldn't work, STM32F401 discovery board was made with HC-49 for the 8MHz.

    For the pth ceramic capacitors, as long as you put the right value, it should be fine too.

    Hello,

    Sorry the question is not clear. Do you need to use SMD crystals or not?

    Do you have datasheets of these crystals?
