Is there a pin-compatible replacement for Q13FC13500005?

Yes, several crystals in a 3215 package are pin-compatible. However, you must verify critical electrical parameters like load capacitance (12.5pF) and frequency tolerance to ensure functional compatibility.

What risks should I check before replacing Q13FC13500005?

Before replacing, check three main risks: 1) Frequency Tolerance: most alternatives are ±20ppm, a downgrade from ±10ppm. 2) Load Capacitance: ensure it matches 12.5pF to avoid frequency shift. 3) Operating Temperature: confirm the replacement supports the required -40°C to 85°C range.

Q13FC13500005 Alternatives, Datasheet & Cross Reference | EPSON

The EPSON Q13FC13500005 is a high-precision (±10ppm) 32.768kHz crystal. While many alternatives share its 3215 package and 12.5pF load capacitance, most offer a standard ±20ppm tolerance, which requires careful consideration for timing-critical applications.

AI replacement insight

Electrical riskmedium

Weaker frequency tolerance can impact performance in precision RTC or communication applications.

Package risklow

The 3215 package is standard, ensuring physical compatibility with most candidates.

Can it be replaced directly?

There are no direct replacements with identical ±10ppm tolerance among the candidates. The closest alternatives, like NDK's NX3215SA-32.768KHZ-EXS00A-MU00466, are a parametric downgrade to ±20ppm tolerance.

Best replacement path

Select a substitute with a matching 12.5pF load capacitance and -40°C to 85°C temperature range, but verify if the application can tolerate a downgrade from ±10ppm to ±20ppm frequency tolerance.

Main risk

The primary risk is reduced timing accuracy due to the wider frequency tolerance (±20ppm) of most available alternatives compared to the target's ±10ppm.

Recommended alternatives

Matches package and load capacitance, but has a weaker frequency tolerance. Review for precision timing circuits.
