The DSC8001AI5-PROGRAMMABLE: No pin-compatible second-source is listed in the Microchip documentation, so the BOM position is single-sourced to this order code.
The DSC8001AI5-PROGRAMMABLE is available to order through independent distribution.
The DSC8001 series shares the same 4-SMD footprint and supply voltage range, but each order code is factory-programmed to a specific frequency range — a different code means a different frequency band.
