Substitute Part Grouping Explanation

Substitution eligibility for the AX7PBF4-1000.0000C 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: ±25ppm (timing tolerance)
• Operating Temperature Range: -40°C ~ 85°C (environmental specification)
• Package Type: 8-SMD, No Lead (PCB layout compatibility)
• Package Dimensions: 7.00mm x 5.00mm (footprint constraint)
• Compliance: ROHS3, MSL 1 (regulatory and handling requirements)

The AX7PBF1-1000.0000C meets all substitution criteria as a parametric equivalent within the ClearClock™ AX7 series.

Engineering Selection Recommendations

Both the AX7PBF4-1000.0000C and AX7PBF1-1000.0000C are discontinued products at DiGi Electronics. Selection between these parts should be based on:

• Inventory availability: The main part (AX7PBF4) has higher stock (1011 Pcs vs. 829 Pcs)
• Compliance requirements: Both parts meet ROHS3 and REACH requirements
• Handling requirements: Both parts carry MSL 1 rating, requiring no special moisture control during storage and handling
• Long-term sourcing: Given discontinuation status, either part may face future availability constraints

No electrical or mechanical differentiation exists between these components based on provided specifications.

Frequently Asked Questions (FAQ)

Q: Can the AX7PBF1-1000.0000C be used as a direct replacement for the AX7PBF4-1000.0000C?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, frequency output, supply voltage, enable/disable function, and package dimensions. No circuit modifications are required.

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

A: No differences are specified in the provided parameters. Both use the same 8-SMD, No Lead package with identical dimensions (7.00mm x 5.00mm x 1.90mm max height).

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™ AX7 series. Both revisions meet identical electrical and mechanical specifications for this 1 GHz LVPECL oscillator application.

Q: Are both parts suitable for high-reliability applications?

A: Both parts are ROHS3 compliant and carry MSL 1 rating. Compliance certifications are identical. Application suitability depends on specific system requirements beyond the provided parameters.

Q: What is the impact of the discontinued status on these parts?

A: Both parts are discontinued at DiGi Electronics. Current inventory levels are limited (1011 Pcs and 829 Pcs respectively). Long-term availability cannot be guaranteed. Alternative sourcing channels or design migration may be necessary for future production requirements.
