Substitute Part Grouping Explanation

Substitution of the AX7PBF4-1800.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 1.8 GHz (exact match required)
• Output Type: LVPECL (signal standard compatibility)
• Supply Voltage: 2.5V (power supply compatibility)
• Function: Enable/Disable (operational feature match)
• Frequency Stability: ±25ppm (timing accuracy specification)
• Operating Temperature Range: -40°C ~ 85°C (environmental specification)
• Package Type: 8-SMD, No Lead (physical and electrical footprint compatibility)
• Package Dimensions: 7.00mm x 5.00mm (board layout compatibility)
• Compliance: ROHS3 Compliant, Moisture Sensitivity Level 1

The AX7PBF1-1800.0000C meets all these criteria and is classified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The AX7PBF1-1800.0000C is a direct parametric equivalent to the AX7PBF4-1800.0000C. Both parts are manufactured by Abracon LLC within the ClearClock™ AX7 series and share identical electrical and mechanical specifications. The substitute part maintains full compliance with ROHS3 and REACH requirements, with equivalent moisture sensitivity classification.

Selection between these parts should be based on inventory availability and supply chain considerations. The AX7PBF1-1800.0000C currently has higher inventory availability (1047 Pcs vs. 799 Pcs), making it the preferred choice for new procurement when the primary part number is unavailable.

Frequently Asked Questions (FAQ)

Q: Can the AX7PBF1-1800.0000C be used as a direct replacement for the AX7PBF4-1800.0000C?

A: Yes. Both parts are parametric equivalents with identical frequency, output type, supply voltage, temperature range, package type, and all electrical specifications. Direct substitution is supported without circuit modification.

Q: Are there any differences in pin configuration or footprint between these parts?

A: No. Both parts use the same 8-SMD, No Lead package with identical dimensions (7.00mm x 5.00mm x 1.90mm max height). PCB layout and assembly processes remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the AX7PBF4-1800.0000C and AX7PBF1-1800.0000C are ROHS3 compliant, REACH unaffected, and classified as Moisture Sensitivity Level 1 (unlimited shelf life).

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

A: The suffix variation indicates different manufacturing batches or revisions within the Abracon ClearClock™ AX7 series. Both maintain identical electrical and mechanical specifications for the 1.8 GHz LVPECL oscillator configuration.

Q: Are there any supply current differences between the two parts?

A: No. Both parts have identical maximum supply current specifications: 94mA during normal operation and 86mA in disable mode.
