402F2001XILR

Crystals Overview

The CTS-Frequency Controls 402F2001XILR is a surface-mount fundamental mode crystal oscillator designed for precision timing applications. It operates at a nominal frequency of 20 MHz with a frequency tolerance of ±10 ppm and stability of ±15 ppm. The component features an equivalent series resistance (ESR) of 100 Ohms and a load capacitance of 12 pF. Housed in a compact 4-SMD, No Lead package measuring 2.00mm x 1.60mm with a maximum seated height of 0.55mm, it supports an operating temperature range of -40°C to +85°C. The device is RoHS3 compliant and classified under MSL Level 1.

Crystals Procurement Notes

Verify the specific suffix 'XILR' against the manufacturer's current datasheet to confirm active status and exact electrical parameters. Check for potential obsolescence or lifecycle changes as distribution channels may list discontinued variants. Ensure compatibility with the target circuit's load capacitance requirements before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 20 MHz fundamental crystal with ±10 ppm tolerance is required. Compare ESR and load capacitance values against the host oscillator circuit specifications. Consider the 4-SMD footprint constraints and thermal performance within the -40°C to +85°C range relative to other available packages in the 402 series.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. Variants within this series share similar physical dimensions but differ in frequency, tolerance, and load capacitance. The 402F2001XILR specifically denotes the 20 MHz variant with 12pF load capacitance and hermetic sealing, distinguishing it from non-hermetic or different tolerance options like the 402F200XXCKT.

Crystals Replacement Considerations

Direct substitutes include the 402F2001XIAR and 402F2001XILT from CTS-Frequency Controls, which share the same 20 MHz frequency and 4-SMD package form factor. Verify that alternative manufacturers offer components matching the 12pF load capacitance and 100 Ohm ESR specifications to ensure circuit compatibility.
