Substitute Part Grouping Explanation

Substitution of the AX7DBF2-400.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 400 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Supply Voltage: 2.5V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Package / Case: 8-SMD, No Lead (exact match required)
• Dimensions: 7.00mm x 5.00mm (exact match required)
• Maximum Seated Height: 1.90mm (exact match required)

The AX7DBF1-400.0000C meets all substitution criteria as a parametric equivalent within the ClearClock™ AX7 series.

Frequently Asked Questions (FAQ)

Q: Can the AX7DBF1-400.0000C be used as a direct replacement for the AX7DBF2-400.0000C?

A: Yes. The AX7DBF1-400.0000C is a parametric equivalent with identical frequency, output type, supply voltage, function, frequency stability, operating temperature range, package dimensions, and electrical characteristics.

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 dimensions of 7.00mm x 5.00mm and a maximum seated height of 1.90mm.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the AX7DBF2-400.0000C and AX7DBF1-400.0000C are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the difference between the part numbers if they are equivalent?

A: The part numbers differ only in the suffix designation (DBF2 versus DBF1). Both parts are from the same ClearClock™ AX7 series and share identical electrical and mechanical specifications.

Q: Are there any supply current differences between these parts?

A: No. Both parts have a maximum supply current of 70mA during operation and 65mA during disable mode.
