Key Parameters

Substitute Part Grouping Explanation

The FD0810004 qualifies as a direct substitute for the FD0810003 based on the following critical parameters:

• Identical frequency: 8.192 MHz
• Identical output type: CMOS
• Identical supply voltage: 3.3V
• Identical function: Enable/Disable
• Identical package type and dimensions: 4-SMD, No Lead (5.00mm x 3.20mm x 1.30mm Max Height)
• Identical operating temperature range: -20°C ~ 70°C
• Identical supply current maximum: 15mA
• Identical disable current maximum: 10µA
• Identical RoHS and MSL compliance

The primary difference is frequency stability specification, where FD0810004 provides ±25ppm versus FD0810003 at ±50ppm. This represents an upgrade in frequency accuracy.

Parameter Comparison

Engineering Selection Recommendations

Both FD0810003 and FD0810004 are Active status products from Diodes Incorporated with full ROHS3 compliance and REACH unaffected status. Selection between these parts depends on frequency stability requirements:

• FD0810003 (±50ppm stability) is suitable for applications where standard frequency tolerance is acceptable.
• FD0810004 (±25ppm stability) provides improved frequency accuracy for applications requiring tighter tolerance control.

Both parts are pin-compatible, mechanically identical, and electrically interchangeable within their specified operating parameters. No circuit modifications are required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can FD0810004 replace FD0810003 in existing designs?

A: Yes. FD0810004 is a direct substitute with identical electrical and mechanical specifications. The improved frequency stability of ±25ppm versus ±50ppm represents an upgrade path with no design changes required.

Q: Are the package dimensions identical?

A: Yes. Both parts use the same 4-SMD, No Lead package with dimensions of 5.00mm x 3.20mm and maximum seated height of 1.30mm. PCB footprints are identical.

Q: What is the difference between these two parts?

A: The primary difference is frequency stability specification. FD0810004 provides ±25ppm stability compared to FD0810003 at ±50ppm. All other electrical and mechanical parameters are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both FD0810003 and FD0810004 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can FD0810003 replace FD0810004?

A: FD0810003 can replace FD0810004 only in applications where the wider ±50ppm frequency tolerance is acceptable. If the design requires ±25ppm stability, FD0810003 does not meet the specification.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -20°C to 70°C. Supply current remains at 15mA maximum during operation and 10µA maximum in disable mode across this entire temperature range.
