Functional alternative with same frequency and package, but requires changing external load capacitors.
Finding a replacement for the SJK 7U08000E10UCG 8MHz crystal requires matching frequency, package, and load capacitance. Alternatives may require circuit adjustments for the different load capacitance.
Mismatched load capacitance requires redesign of external capacitor network.
Package is a standard SMD3225, ensuring physical compatibility.
No direct pin-for-pin replacement was found. Available alternatives with matching frequency and package differ in critical electrical parameters like load capacitance, which requires circuit changes.
A functional alternative like HY8MSMD3225OB1R30 exists but requires redesigning the external capacitor network to match its 20pF load capacitance.
The primary risk is a frequency shift or failure to oscillate if the load capacitance is not matched by changing external components.

| Feature / factor | 7U08000E10UCG | HY8MSMD3225OB1R30 | Alt 2 | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Frequency | 8.000MHz | 8MHz | 8MHz — Nominal frequency matches. | ||
| Package | SMD3225 | SMD3225 | SMD3225 — Package size is compatible. | ||
| Load Capacitance | 10pF | 20pF | 20pF — Requires changing external capacitors. | ||
| Frequency Stability | Not specified, assumed better | ±30ppm | ±30ppm — Candidate has wider stability tolerance. | ||
| Esr | 250Ω Max | ≤180Ω | ≤180Ω — Lower ESR is generally favorable. |
HY8MSMD3225OB1R30 is a potential functional alternative, but it requires changing the external load capacitors to match its 20pF requirement, as the original part uses 10pF.
