RV-8523-C3
Epson alternative: RX8130CE
You want to replace the RV-8523-C3 from Micro Crystal — as a second source, because of availability, or because a new design is coming up. Here the type is set against the closest Epson type feature by feature, with the points that speak for and against the change.
Features of the RV-8523-C3: no longer listed in Micro Crystal's current product overview.

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.
The difference
- The RV-8523-C3 no longer appears in Micro Crystal's current product overview — for a new design it is not a sound choice.
- The RX8130CE is the closest current type: I²C, crystal integrated and factory-trimmed, 300 nA typical standby current, 1.25 to 5.5 V — the same class, likewise without temperature compensation.
- Package and pinout differ (C3 3.7 × 2.5 × 0.9 mm against CE 3.2 × 2.5 × 1.0 mm). Plan for a layout change, not a drop-in.
- Because the RV-8523-C3 datasheet figures are no longer published, we compare against your actual requirement instead of a catalogue number. Tell us supply range, accuracy and quantity.
Frequently asked questions
What is the Epson alternative to the RV-8523-C3?
The closest current type is the RX8130CE: I²C, crystal integrated and factory-trimmed, 300 nA typical standby current, 1.25 to 5.5 V supply, no temperature compensation — the same class as the RV-8523-C3. Package and pinout differ, so plan for a layout change rather than a drop-in. Tell us supply range and required accuracy and we will confirm the type for your application.
Is the RV-8523-C3 still available?
The type no longer appears in the manufacturer's current product overview (as of November 2025). For new designs it is therefore no longer a sound choice.
Who supplies an alternative to the RV-8523-C3 in Europe?
Timing Devices Europe in Ladenburg near Heidelberg, Germany stocks the complete Epson RTC programme in its own warehouse — physically on site, not at the manufacturer. Samples, comparison and series demand in one go, answered the same working day.
