Substitute Part Grouping Explanation

The AX7PAF1-300.0000C has one parametric equivalent substitute: AX7PAF3-300.0000C. This substitution is valid based on the following critical parameters that determine functional interchangeability:

• Frequency: 300 MHz (identical)
• Output Type: LVPECL (identical)
• Supply Voltage: 3.3V (identical)
• Function: Enable/Disable (identical)
• Frequency Stability: ±25ppm (identical)
• Operating Temperature Range: -40°C ~ 85°C (identical)
• Package Type: 8-SMD, No Lead (identical)
• Package Dimensions: 7.00mm x 5.00mm x 1.90mm (identical)
• Max Supply Current: 94mA (identical)
• RoHS Compliance: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

Both parts are from the same manufacturer (Abracon LLC) and ClearClock™ AX7 series, with all electrical and mechanical specifications matching exactly.

Parameter Comparison

Engineering Selection Recommendations

Both the AX7PAF1-300.0000C and AX7PAF3-300.0000C are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement. The AX7PAF3-300.0000C is currently available with 1127 pieces in stock, compared to the discontinued AX7PAF1-300.0000C. For applications requiring the 300 MHz LVPECL oscillator with 3.3V supply and enable/disable functionality, the AX7PAF3-300.0000C provides direct functional replacement with identical electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can the AX7PAF3-300.0000C directly replace the AX7PAF1-300.0000C in existing designs?

A: Yes. Both parts share identical frequency (300 MHz), output type (LVPECL), supply voltage (3.3V), function (enable/disable), frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), package type (8-SMD, No Lead), and package dimensions (7.00mm x 5.00mm x 1.90mm). No circuit modifications are required.

Q: Are there any differences in compliance or certifications between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: What is the significance of the different part number suffixes (AX7PAF1 vs. AX7PAF3)?

A: The suffix variation indicates different internal configurations within the ClearClock™ AX7 series. However, all specified electrical and mechanical parameters are identical, making them functionally equivalent for this 300 MHz LVPECL application.

Q: Are the current consumption specifications identical?

A: Yes. Both parts have maximum supply current of 94mA and maximum supply current in disable mode of 86mA.

Q: What is the package footprint compatibility?

A: Both parts use the same 8-SMD, No Lead package with identical dimensions of 7.00mm length x 5.00mm width x 1.90mm maximum seated height, ensuring PCB layout compatibility.
