Substitute Part Grouping Explanation

Substitution for the AX7PBF2-2100.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 2.1 GHz (exact match required)
• Output Standard: LVPECL (no alternative output types acceptable)
• Supply Voltage: 2.5V (no voltage derating permitted)
• Function: Enable/Disable capability (required for system control)
• Package Type: 8-SMD, No Lead (physical and electrical compatibility)
• Package Dimensions: 7.00mm x 5.00mm footprint (PCB layout constraint)
• Operating Temperature Range: -40°C ~ 85°C (system thermal specification)
• Frequency Stability: ±25ppm (timing accuracy requirement)

The identified substitute part maintains identical electrical specifications, mechanical compatibility, and environmental ratings. Substitution is valid only when all parameters match exactly as specified.

Parameter Comparison

Engineering Selection Recommendations

Both the main part (AX7PBF2-2100.0000C) and substitute part (AX7PBF1-2100.0000C) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Both parts maintain identical electrical performance specifications and physical package compatibility. Selection between these parts should be based on current inventory availability and supply chain lead times, as both are functionally equivalent for system integration. The substitute part currently shows higher inventory availability (1097 Pcs vs. 791 Pcs), which may influence procurement decisions for new production runs or design revisions.

Frequently Asked Questions (FAQ)

Q: Can AX7PBF1-2100.0000C be used as a direct replacement for AX7PBF2-2100.0000C?

A: Yes. Both parts are parametrically equivalent across all critical specifications including frequency, output type, supply voltage, package type, and operating temperature range. Direct PCB substitution is valid without design modifications.

Q: Are there any differences in the package footprint between these parts?

A: No. Both parts use identical 8-SMD, No Lead packaging with 7.00mm x 5.00mm dimensions and 1.90mm maximum seated height. PCB layout and assembly processes remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1 - Unlimited). Environmental and regulatory requirements are met by both parts.

Q: What is the significance of the part number suffix difference (PBF2 vs. PBF1)?

A: The suffix indicates internal manufacturing or revision variations within the Abracon AX7 series. Both variants maintain identical electrical and mechanical specifications for the 2.1 GHz LVPECL oscillator configuration.

Q: Are the supply current specifications identical?

A: Yes. Both parts specify 94mA maximum supply current during normal operation and 86mA maximum during disable mode, ensuring equivalent power consumption profiles in system designs.
