Some HMC products are/will be obsolete due to foundry/process discontinuation. Many of these have/will have replacement products designed in a similar process from a different foundry targeting functional drop-in replacement. "A" suffix on the part number is used to identify replacement products.
The HMC349A/HMC472A are the FFF (form, fit, functional) replacements of the HMC349/HMC472 and existing applications of original parts can switch to replacement parts without any change in design/performance.
