We know
what is inside.

Security of supply is the first question here, not the last: our own warehouse in Ladenburg, a named contact, and a successor part ready before a component is discontinued.

Real-time clocks — our focus

Every Epson RTC.
One address.

Modules with the crystal already trimmed inside the package: one component instead of an IC plus a crystal plus two capacitors. We carry the complete Epson programme — the I²C line, the SPI line, the low-power types and the automotive grades on request.

Compensated across the whole rangeDTCXO types hold their accuracy from −40 °C to +125 °C, not only at +25 °C. In most designs that is the point where the decision is made.
A successor for every discontinued typeThe JE and NB packages ship for the last time in October 2026. For each of the six we show the same-series route and the CE successor side by side.

End of life

A part going end of life?

Six Epson package variants and three NXP classics are being discontinued right now. For each of them we show the successor with a side-by-side comparison — not just an “obsolete” note.

Focus 2 — cross-reference & security of supply

Competitor part in.
Alternative out.

Type in the part number you want to replace and you get a qualified alternative from our programme — with the reasoning behind it, not just a table row. And behind the alternative stands the part that matters most: one that is actually available.

Security of supply

Our own warehouse in LadenburgPhysically on site near Heidelberg, in the Rhine-Neckar region — not at the manufacturer and not on a drop-ship route. What is in stock leaves the same day.
A named contact, not a ticket queueOne person who knows your parts and your project. Enquiries are answered on the same business day.
The successor before the last order dateWe follow the discontinuation notices of our manufacturers and come to you with the successor and a comparison while there is still time to change the design.
