The DSC6121HA3B-01QJ: Housed in a 4-VFLGA (1.60 mm × 1.20 mm, 0.89 mm seated height), the footprint matches standard 4-pin oscillator land patterns — no special via-in-pad or thermal-relief rules beyond the usual for a 0.50 mm pitch LGA.
Listed as Active — Microchip continues to manufacture this part with no announced end-of-life.
