Obsolete — last-time-buy sourcing
The DSC6111MI2A-025.0000: No official successor is listed, so any replacement means a board-level change — same footprint, different part number, possibly a different MEMS vendor. We source this through independent surplus channels, lot-specific and confirmed at RFQ. No stock-holding claim; availability and pricing are per the BOM quantity.
4-pin SMD — orientation on the board
Pin 1 is the standby control; pin 2 is ground; pin 3 is output; pin 4 is supply. The package is symmetric but the pin-1 chamfer is visible under magnification — no lab bench needed to orient it, just a good pair of tweezers and a steady hand.
