Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The small footprint suits space-constrained PCBs in portable or multi-layer designs. No-lead packages require careful solder-paste stencil design and X-ray inspection for voiding under the terminations.
Yes, the product status is Obsolete. No official successor is listed.
No official replacement is listed by Microchip Technology. A functionally equivalent MEMS oscillator in the same 4-SMD no-lead package and 40 MHz frequency may be sourced from other manufacturers; cross-reference confirmation against the original PCB footprint and supply voltage is required before substitution.
Yes, the specified supply voltage is 3.3 V. The oscillator operates from that rail and delivers CMOS-level output. Ensure the supply decoupling follows the datasheet recommendation to maintain ±25 ppm stability.
