Difference between TLA 6T213HF and TLA 6T213LF

The TLA 6T213HF chip on my Logicboard broke and it needs to be replaced. It says TDk 6T213HF on the chip and TLA 6T213HF in the schematics. I googled it and found the HF version but the datasheets say LF and the LF is easier to find and I think the supply is more. I need to know what the difference between the HF and LF version.

Kind regards
