Substitute Part Grouping Explanation

Substitution of the AX7PBF4-2100.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 2.1 GHz (exact match required)
• Output Signaling: LVPECL (no alternative output types acceptable)
• Supply Voltage: 2.5V (exact match required)
• Enable/Disable Function: Required for system control compatibility
• Frequency Stability: ±25ppm (tolerance specification must be met or exceeded)
• Operating Temperature Range: -40°C ~ 85°C (minimum required range)
• Package Type: 8-SMD, No Lead (physical and electrical interface compatibility)
• Package Dimensions: 7.00mm x 5.00mm footprint (PCB layout compatibility)
• Compliance: ROHS3 Compliant, MSL 1 rating

The AX7PBF1-2100.0000C qualifies as a parametric equivalent substitute based on identical specifications across all critical electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the AX7PBF1-2100.0000C be used as a direct replacement for the AX7PBF4-2100.0000C?

A: Yes. Both parts are parametric equivalents with identical frequency (2.1 GHz), output type (LVPECL), supply voltage (2.5V), enable/disable function, frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), and 8-SMD package dimensions. No circuit modifications are required.

Q: Are there any differences in the physical package between these two part numbers?

A: No. Both components use the same 8-SMD, No Lead package with identical dimensions of 7.00mm x 5.00mm x 1.90mm maximum height. PCB footprints and mounting procedures are identical.

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

A: Yes. Both the AX7PBF4-2100.0000C and AX7PBF1-2100.0000C are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. They are equivalent in terms of regulatory compliance and environmental handling requirements.

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

A: The suffix variation indicates different manufacturing batches or internal Abracon LLC product line designations within the same ClearClock™ AX7 series. The electrical and mechanical specifications remain identical, making them functionally interchangeable.

Q: Can I mix these two part numbers in the same production run?

A: Yes. Since both parts are parametric equivalents with identical specifications, they can be used interchangeably in the same design and production environment without affecting circuit performance or reliability.
