Epson MC-406 and MA-406 crystals will be obsolete by the end of 2020 [3]. The EOL status of Epson’s MC-406 and MA-406 crystals will leave current users searching for substitutes. Fortunately, Suntsu is offering a drop-in replacement with our newest crystals: SWS144 and SXT144.
Below is a comparison of SWS144 and SXT144 vs MC-406 and MA-406 crystals.
• The SWS144 has identical dimensions and electrical parameters as the MC-406.
• The SXT144 is a bit larger than the MA-406, but the pad size and layout remain the same.
Some of their key features are listed below.
SUNTSU SWS144
• Frequency of 32.768kHz
• Package size of 10.41×4.06mm
• Frequency tolerance of ±10ppm or ±20ppm
• Equivalent series resistance of 50kΩ
• Operating temperature range from -40°C to 85°C
