• Function: Enable/Disable capability
• Package Type: 8-SMD, No Lead
• Package Dimensions: 5.00mm x 3.20mm
• Frequency Stability: ±20ppm
• Operating Temperature Range: -40°C ~ 85°C
• Maximum Supply Current: 80mA
• Compliance: ROHS3 Compliant, Moisture Sensitivity Level 1

The AX5DAF1-300.0000C meets all specified parameters and is classified as a parametric equivalent within the ClearClock™ AX5 series.

Parameter Comparison

Engineering Selection Recommendations

Both the AX5DAF4-300.0000C and AX5DAF1-300.0000C are discontinued at DiGi Electronics. Selection between these parts should be based on current inventory availability and procurement lead times. Both parts carry identical electrical specifications, mechanical dimensions, and compliance certifications (ROHS3, REACH Unaffected, EAR99). The AX5DAF1-300.0000C currently maintains higher inventory levels (931 Pcs) compared to the AX5DAF4-300.0000C (1106 Pcs), though both are available as new original stock. PCB layout and thermal management considerations remain unchanged between these equivalent parts due to identical package geometry and thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can the AX5DAF1-300.0000C be used as a direct replacement for the AX5DAF4-300.0000C?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output characteristics, supply voltage, frequency stability, operating temperature range, and package dimensions. No circuit modifications or PCB redesign are required.

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

A: No. Both parts use the same 8-SMD, No Lead package with identical pin assignments and functionality.

Q: What is the significance of the part number suffix difference (AX5DAF4 vs. AX5DAF1)?

A: The suffix variation indicates different internal design revisions within the ClearClock™ AX5 series. Both revisions meet the same parametric specifications and are functionally interchangeable.

Q: Are both parts suitable for the same PCB assembly process?

A: Yes. Identical package dimensions (5.00mm x 3.20mm), maximum seated height (1.50mm), and Moisture Sensitivity Level (1) ensure compatibility with standard surface mount assembly processes.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99.
