Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX5PBF4-1000.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 1 GHz (exact match required)
• Output Type: LVPECL (signal integrity dependent)
• Supply Voltage: 2.5V (circuit compatibility)
• Function: Enable/Disable (operational requirement)
• Frequency Stability: ±20ppm (timing accuracy)
• Operating Temperature Range: -40°C ~ 85°C (environmental specification)
• Maximum Supply Current: 110mA (power budget)
• Package Type: 8-SMD, No Lead (PCB layout compatibility)
• Package Dimensions: 5.00mm x 3.20mm (footprint requirement)
• RoHS Status: ROHS3 Compliant (regulatory requirement)

The AX5PBF1-1000.0000C meets all these criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the AX5PBF4-1000.0000C and AX5PBF1-1000.0000C are discontinued at DiGi Electronics. Selection between these parts should be based on current inventory availability and supply chain status. Both components carry identical electrical specifications, mechanical dimensions, and regulatory compliance certifications (ROHS3, REACH Unaffected). The AX5PBF1-1000.0000C currently maintains higher inventory levels (894 Pcs vs. 973 Pcs for the main part), making it a viable alternative for production continuity. No functional differences exist between these components; substitution is direct and does not require circuit redesign or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can the AX5PBF1-1000.0000C be used as a direct replacement for the AX5PBF4-1000.0000C?

A: Yes. Both components are parametric equivalents with identical electrical characteristics, frequency output, supply voltage, enable/disable functionality, and package specifications. Direct substitution is supported without circuit modification.

Q: Are there any differences in the 8-SMD, No Lead package between these parts?

A: No. Both components use the same package type with identical dimensions (5.00mm x 3.20mm x 1.50mm max height) and pin configuration. PCB footprints are interchangeable.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the AX5PBF4-1000.0000C and AX5PBF1-1000.0000C are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is MSL 1 (unlimited) for both components.

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

A: The suffix variation indicates different internal design revisions within the ClearClock™ AX5 series. Both revisions maintain identical electrical and mechanical specifications for the 1 GHz LVPECL oscillator at 2.5V with enable/disable functionality.

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

A: No. Maximum supply current is 110mA for both components. Disable mode current is 100mA for both parts.
