What speaks for and against the change

We sell Epson — and we still say where the competitor is better. You would notice it at the first datasheet comparison anyway.

Where the RV-8263-C7 is ahead

Honestly

  • Starts from 0.9 V
  • The C8 package is considerably smaller than the Epson CE
Where Epson wins

The difference

  • ±20 ppm at +25 °C — the RX8130CE is on par at +5 ±23 ppm but adds a reset output with delay, a V_IO pin and charge control with full-charge detection
  • No self-monitoring
Not a drop-in: package, pinout and register map differ between manufacturers. Budget for a layout change and a driver adaptation — we will supply the documents for both sides.
