Substitute Part Grouping Explanation

Substitution eligibility for the AX5PBF4-1800.0000C is determined by strict equivalence across the following critical parameters:

Frequency specification (1.8 GHz), output signal type (LVPECL), supply voltage (2.5V), enable/disable control function, frequency stability (±20ppm), operating temperature range (-40°C ~ 85°C), package configuration (8-SMD, No Lead), and physical dimensions (5.00mm x 3.20mm x 1.50mm maximum height).

The substitute part AX5PBF1-1800.0000C meets all these criteria, maintaining identical electrical and mechanical specifications within the same ClearClock™ AX5 series.

Parameter Comparison

Engineering Selection Recommendations

The AX5PBF1-1800.0000C is a direct parametric equivalent to the AX5PBF4-1800.0000C. Both parts are manufactured by Abracon LLC within the same ClearClock™ AX5 series and maintain identical electrical performance, frequency stability, and physical package specifications. Both parts carry ROHS3 compliance and MSL 1 rating, ensuring equivalent environmental and regulatory compliance.

Selection between these parts should be based on component availability and procurement lead times, as all functional and mechanical parameters are identical.

Frequently Asked Questions (FAQ)

Q: Can AX5PBF1-1800.0000C be used as a direct replacement for AX5PBF4-1800.0000C?

A: Yes. Both parts are parametric equivalents with identical frequency (1.8 GHz), output type (LVPECL), supply voltage (2.5V), frequency stability (±20ppm), operating temperature range (-40°C ~ 85°C), and package configuration (8-SMD, No Lead, 5.00mm x 3.20mm x 1.50mm). No circuit modifications are required.

Q: Are there any differences in current consumption between these parts?

A: No. Both parts specify maximum supply current of 110mA and disable mode current of 100mA.

Q: Do both parts meet the same compliance standards?

A: Yes. Both AX5PBF4-1800.0000C and AX5PBF1-1800.0000C are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of the different part number suffixes (PBF4 vs. PBF1)?

A: The suffix variation indicates different internal design revisions or manufacturing batches within the same functional specification. Both parts maintain identical electrical and mechanical parameters for the 1.8 GHz LVPECL oscillator application.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Identical package dimensions (5.00mm x 3.20mm) and 8-SMD, No Lead configuration ensure direct PCB footprint compatibility without layout modifications.
