Substitute Part Grouping Explanation

The AX5PAF1-300.0000C has one parametric equivalent substitute: AX5PAF3-300.0000C. This substitution is valid based on the following criteria:

Critical Matching Parameters:

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

The substitute part differs only in internal design variant (PAF3 vs. PAF1), while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the AX5PAF1-300.0000C and AX5PAF3-300.0000C are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The AX5PAF3-300.0000C is currently available with 613 units in stock, while the original AX5PAF1-300.0000C is discontinued at DiGi Electronics with 960 units remaining in inventory. For new designs or replenishment, the AX5PAF3-300.0000C provides equivalent electrical performance and mechanical compatibility with assured supply availability.

Frequently Asked Questions (FAQ)

Q: Can AX5PAF3-300.0000C be used as a direct replacement for AX5PAF1-300.0000C?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including frequency, output type, supply voltage, temperature range, and package dimensions. The substitution is direct with no circuit modifications required.

Q: Are there any differences in pin configuration or signal integrity between these parts?

A: No. Both parts use the same 8-SMD, No Lead package with identical dimensions and pinout. Signal integrity characteristics remain consistent due to matching electrical specifications.

Q: What is the significance of the PAF1 and PAF3 designations?

A: These designations indicate internal design variants within the ClearClock™ AX5 series. Both variants meet the same electrical and mechanical specifications for this 300 MHz LVPECL oscillator application.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -40°C to 85°C with the same frequency stability of ±20ppm.

Q: What is the current consumption difference between normal and disable modes?

A: In normal operation, both parts draw a maximum of 110mA. In disable mode, current consumption is reduced to a maximum of 100mA, providing power management capability in both variants.
