Substitute Part Grouping Explanation

Substitute parts for the AX5PAF2-300.0000C are determined by strict equivalence across the following critical parameters:

• Frequency: 300 MHz
• Output Type: LVPECL
• Supply Voltage: 3.3V
• Function: Enable/Disable capability
• Frequency Stability: ±20ppm
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 8-SMD, No Lead
• Package Dimensions: 5.00mm x 3.20mm
• Maximum Height: 1.50mm
• Supply Current Ratings: 110mA (active), 100mA (disable)
• Compliance: ROHS3 Compliant, Moisture Sensitivity Level 1

The AX5PAF3-300.0000C meets all these criteria and is classified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The AX5PAF3-300.0000C currently has 613 units in stock, while the AX5PAF2-300.0000C has 790 units available. Both parts are discontinued at DiGi Electronics, making inventory verification essential before design implementation.

Frequently Asked Questions (FAQ)

Q: Can the AX5PAF3-300.0000C be used as a direct replacement for the AX5PAF2-300.0000C?

A: Yes. The AX5PAF3-300.0000C is a parametric equivalent substitute. All electrical specifications, frequency output, supply voltage, enable/disable function, frequency stability, operating temperature range, and package dimensions are identical. No circuit modifications are required.

Q: Are there any differences in the pin configuration or package footprint?

A: No. Both parts use the same 8-SMD, No Lead package with identical dimensions of 5.00mm x 3.20mm and maximum height of 1.50mm. PCB footprints are interchangeable.

Q: What is the significance of the part number suffix difference between AX5PAF2 and AX5PAF3?

A: The suffix difference indicates internal design variations within the ClearClock™ AX5 series. However, both variants meet identical parametric specifications for this 300 MHz LVPECL oscillator application, making them functionally equivalent for design purposes.

Q: Are both parts RoHS compliant?

A: Yes. Both the AX5PAF2-300.0000C and AX5PAF3-300.0000C are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting environmental and regulatory requirements.

Q: What should be verified before selecting a substitute part?

A: Verify current inventory availability, as both parts are discontinued at DiGi Electronics. Confirm that the 300 MHz frequency, LVPECL output, 3.3V supply voltage, and Enable/Disable function match your circuit requirements. Validate that the 8-SMD, No Lead package and 5.00mm x 3.20mm footprint are compatible with your PCB layout.
