Product details

The DSC1033BI1-050.0000 is a 50 MHz MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a CMOS output at 3.3V with ±50ppm frequency stability. The 4-SMD no-lead package (5.00mm x 3.20mm footprint) is a common oscillator form factor — the board layout matches many standard 5x3.2 mm XOs, so a drop-in swap from a quartz part is straightforward as long as the supply and output type align.

Expect date-code mixing across lots; each tube should be visually inspected for marking consistency and the package checked for signs of rework or re-balling.

Package and temperature grade – board-fit checklist

The 4-SMD no-lead package measures 5.00mm x 3.20mm with a seated height of 0.90mm max. The pad layout is the same as many standard 5x3.2 mm oscillators — confirm the pin-1 orientation and the disable/standby function on pin 1 match your existing footprint.
