The DSC1033DE1-013.5600: No direct pin-compatible replacement has been announced by Microchip.
13.56 MHz fixed-frequency MEMS oscillator
This is a 13.56 MHz XO (Standard) based on a MEMS resonator, not a quartz crystal. Output is CMOS, making it a direct drop-in for digital clock inputs on MCUs, FPGAs, or Ethernet PHYs that expect a square-wave reference.
Active current is 3 mA typ at 13.56 MHz – useful for battery-operated equipment where the clock can be gated off between activity bursts.
Compact 2.5 mm x 2.0 mm SMD package
Housed in a 4-SMD, No Lead package measuring 0.098" x 0.079" (2.50 mm x 2.00 mm) with a seated height of 0.035" (0.90 mm). The small footprint suits space-constrained PCB layouts in portable or handheld designs.
