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 0.098" x 0.079" footprint is common across many MEMS oscillators — a standard land pattern works, but confirm the pin 1 orientation on the actual part marking before stenciling.
Engineers need to know if the part is still in production or must find a replacement for long-term design support.
Buyers and designers require a drop-in alternative to avoid redesign when the original is no longer available.
Design engineers validating fit need pin configuration to ensure compatibility with existing circuit layouts.
Sourcing buyers need current stock levels and distributor availability to fulfill BOM requirements.
Engineers confirm voltage, frequency, stability, and package dimensions to match design requirements.
Brokers and procurement teams check lifecycle status and find interchangeable parts to ensure supply chain continuity.
