Substitute Part Grouping Explanation

Substitution of the AX7PAF2-300.0000C is determined by strict equivalence across the following critical parameters:

Frequency: 300 MHz (exact match required)
Output Type: LVPECL (signal integrity dependent)
Supply Voltage: 3.3V (circuit compatibility)
Function: Enable/Disable (operational requirement)
Package Type: 8-SMD, No Lead (PCB layout compatibility)
Package Dimensions: 7.00mm x 5.00mm (footprint compatibility)
Frequency Stability: ±25ppm (timing accuracy)
Operating Temperature Range: -40°C ~ 85°C (environmental specification)

The AX7PAF3-300.0000C meets all these criteria as a parametric equivalent within the same ClearClock™ AX7 series.

Engineering Selection Recommendations

The AX7PAF3-300.0000C is a direct parametric equivalent to the AX7PAF2-300.0000C. Both parts are discontinued at DiGi Electronics and manufactured by Abracon LLC within the same ClearClock™ AX7 series. Selection between these parts should be based on current inventory availability and procurement lead times, as all electrical, mechanical, and compliance specifications are identical. Both parts maintain ROHS3 compliance and REACH unaffected status, suitable for applications requiring regulatory adherence.

Frequently Asked Questions (FAQ)

Q: Can the AX7PAF3-300.0000C be used as a direct replacement for the AX7PAF2-300.0000C?

A: Yes. Both parts are parametric equivalents with identical frequency, output type, supply voltage, package dimensions, and all electrical specifications. No circuit modifications are required.

Q: Are there any differences in PCB layout or footprint between these parts?

A: No. Both parts use the same 8-SMD, No Lead package with identical dimensions of 7.00mm x 5.00mm x 1.90mm maximum height. PCB layouts are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the AX7PAF2-300.0000C and AX7PAF3-300.0000C are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of the part number suffix difference (AX7PAF2 vs. AX7PAF3)?

A: The suffix indicates a variant within the ClearClock™ AX7 series. For the 300 MHz LVPECL configuration specified, both variants maintain identical electrical and mechanical parameters.

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

A: No. Both parts have identical maximum supply current of 94mA and maximum disable current of 86mA.
