Substitute Part Grouping Explanation

Substitute parts for the AX7DBF3-491.5200C are identified based on strict parametric equivalence across the following critical criteria:

• Frequency: 491.52 MHz (exact match required)
• Output Configuration: LVDS
• Supply Voltage: 2.5V
• Enable/Disable Function: Present
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 8-SMD, No Lead
• Package Dimensions: 7.00mm x 5.00mm
• Maximum Height: 1.90mm

Parts meeting all these parameters are classified as direct parametric equivalents and may be substituted without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The AX7DBF1-491.5200C is a direct parametric equivalent to the AX7DBF3-491.5200C. Both parts are manufactured by Abracon LLC within the ClearClock™ AX7 series and share identical electrical specifications, frequency output, package configuration, and compliance certifications. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications requiring these certifications.

Selection between these parts should be based on availability and procurement lead times, as no functional or performance differentiation exists between them.

Frequently Asked Questions (FAQ)

Q: Can the AX7DBF1-491.5200C be used as a direct replacement for the AX7DBF3-491.5200C?
