Parameter Comparison

Engineering Selection Recommendations

Both FD3680002 and FD3680003 are Active status products from Diodes Incorporated with identical ROHS3 compliance and REACH unaffected status. Selection between these parts depends on application-specific requirements:

Select FD3680002 when:

• Tighter frequency stability of ±25ppm is required
• Operating environment is limited to -20°C ~ 70°C range
• Standard packaging is preferred

Select FD3680003 when:

• Extended operating temperature range of -40°C ~ 85°C is required
• Frequency stability of ±50ppm is acceptable
• Bulk packaging is suitable for production volumes

Both parts maintain identical electrical performance in core parameters: frequency, output type, supply voltage, function, current consumption, and package footprint. The choice between them is determined by environmental operating conditions and frequency stability requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can FD3680003 be used as a direct replacement for FD3680002 in all applications?

A: FD3680003 is electrically and mechanically compatible with FD3680002 for applications operating within the -20°C ~ 70°C range. However, FD3680003 has a wider frequency stability tolerance (±50ppm vs. ±25ppm). Applications requiring the tighter ±25ppm stability of FD3680002 should not substitute with FD3680003.

Q: What is the difference in frequency stability between these parts?

A: FD3680002 provides ±25ppm frequency stability, while FD3680003 provides ±50ppm. The FD3680002 is suitable for applications requiring higher frequency precision. The FD3680003 is suitable for applications where the wider tolerance is acceptable.

Q: Can FD3680003 operate at lower temperatures than FD3680002?

A: Yes. FD3680003 operates from -40°C ~ 85°C, extending the lower temperature limit to -40°C compared to FD3680002's -20°C ~ 70°C range. This makes FD3680003 suitable for applications requiring operation in colder environments.

Q: Are the package dimensions identical between FD3680002 and FD3680003?

A: Yes. Both parts use the same 4-SMD, No Lead package with dimensions of 5.00mm x 3.20mm x 1.30mm (Max Height). They are footprint-compatible for PCB assembly.

Q: What is the difference in packaging between FD3680002 and FD3680003?

A: FD3680002 is supplied in standard packaging, while FD3680003 is supplied in Bulk packaging. This distinction affects order quantities and handling but does not impact electrical or mechanical performance.

Q: Are both parts RoHS compliant?

A: Yes. Both FD3680002 and FD3680003 are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements.
