Substitute Part Grouping Explanation

Substitute parts for the AX7PBF2-2000.0000C are identified based on parametric equivalence within the ClearClock™ AX7 series. All substitute parts maintain identical electrical and mechanical specifications:

• Frequency: 2.0000 GHz
• Output: LVPECL
• Supply Voltage: 2.5V
• Frequency Stability: ±25ppm
• Operating Temperature: -40°C to 85°C
• Current Specifications: 94mA (max), 86mA (disable)
• Package: 8-SMD, No Lead (7.00mm x 5.00mm x 1.90mm)
• Enable/Disable Function: Present
• Compliance: ROHS3, MSL 1

The substitutes differ only in internal design revision (indicated by the PBF1 and PBF3 designations) while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AX7PBF2-2000.0000C, AX7PBF1-2000.0000C, and AX7PBF3-2000.0000C—are parametrically equivalent and interchangeable for applications requiring a 2 GHz LVPECL oscillator with 2.5V supply and enable/disable control. Selection among these parts should be based on inventory availability and procurement lead times, as all maintain identical electrical performance, thermal characteristics, and regulatory compliance (ROHS3, MSL 1).

Current inventory levels are: AX7PBF2 (903 pcs), AX7PBF1 (829 pcs), and AX7PBF3 (1144 pcs). The AX7PBF3 variant offers the highest stock availability.

Frequently Asked Questions (FAQ)

Q: Are AX7PBF1, AX7PBF2, and AX7PBF3 pin-compatible?

A: Yes. All three parts use the identical 8-SMD, No Lead package with matching pinout, dimensions (7.00mm x 5.00mm x 1.90mm), and electrical specifications. Direct substitution on PCBs is supported without layout modifications.

Q: What does the PBF1, PBF2, and PBF3 designation indicate?

A: These designations represent internal design revisions within the ClearClock™ AX7 series. All revisions maintain full parametric equivalence for the 2 GHz LVPECL oscillator specification.

Q: Can these parts be used interchangeably in production?

A: Yes. All three parts meet identical electrical, mechanical, and compliance requirements. They are suitable for direct substitution in designs currently using any variant of this part number family.

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

A: No. All three parts carry identical certifications: ROHS3 compliance, MSL 1 rating, REACH Unaffected status, and EAR99 ECCN classification.

Q: Which part should be selected for new designs?

A: Selection should be based on current inventory availability and supplier lead times. AX7PBF3-2000.0000C currently has the highest stock level (1144 pcs). All variants are electrically and mechanically identical for design purposes.
