Parameter Comparison

Engineering Selection Recommendations

The AX5DAF1-300.0000C is a direct parametric equivalent to the AX5DAF3-300.0000C. Both parts are ROHS3 compliant and carry identical electrical and mechanical specifications. Selection between these parts should be based on availability and inventory status. The AX5DAF1-300.0000C currently maintains higher inventory levels (931 Pcs) compared to the AX5DAF3-300.0000C (982 Pcs), though both are listed as discontinued at DiGi Electronics. For applications requiring this specific oscillator configuration, either part satisfies all parametric requirements without design modification.

Frequently Asked Questions (FAQ)

Q: Can the AX5DAF1-300.0000C be used as a direct replacement for the AX5DAF3-300.0000C?

A: Yes. Both parts are parametric equivalents with identical frequency, output type, supply voltage, current specifications, package type, and operating temperature range. No circuit modifications are required.

Q: Are there any differences in the physical package between these parts?

A: No. Both parts use the same 8-SMD, No Lead package with identical dimensions of 5.00mm L x 3.20mm W x 1.50mm H (maximum seated height).

Q: Do both parts meet the same compliance standards?

A: Yes. Both the AX5DAF3-300.0000C and AX5DAF1-300.0000C are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of the different part number suffixes?

A: The suffix differences (DAF3 versus DAF1) indicate internal design variations within the ClearClock™ AX5 series. However, all parametric specifications remain identical, making them functionally interchangeable for this application.

Q: Are there any current or supply considerations when substituting these parts?

A: No. Both parts have identical maximum supply current (80mA) and disable current (70mA) specifications, ensuring compatibility with existing power supply designs.
