Substitute Part Grouping Explanation

Substitution eligibility for the AX5DAF3-400.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 400 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable capability (exact match required)
• Package Type: 8-SMD, No Lead (exact match required)
• Package Dimensions: 5.00mm x 3.20mm footprint (exact match required)
• Frequency Stability: ±20ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)

The AX5DAF1-400.0000C meets all substitution criteria as a parametric equivalent within the ClearClock™ AX5 series.

Parameter Comparison

Engineering Selection Recommendations

Both the AX5DAF3-400.0000C and AX5DAF1-400.0000C are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The AX5DAF1-400.0000C is available with 766 pieces in stock, providing supply continuity for the discontinued AX5DAF3-400.0000C. Selection between these parts should be based on procurement availability and project timeline requirements, as all electrical and mechanical specifications are identical.

Frequently Asked Questions (FAQ)

Q: Can the AX5DAF1-400.0000C directly replace the AX5DAF3-400.0000C in existing designs?

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

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

A: No. Both parts use the same 8-SMD, No Lead package with identical footprint dimensions of 5.00mm x 3.20mm.

Q: What is the significance of the different part number designations (DAF3 vs. DAF1)?

A: The designation difference reflects internal Abracon LLC product line variations within the ClearClock™ AX5 series. Both maintain identical performance specifications for 400 MHz LVDS oscillator applications.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -40°C to 85°C.

Q: Do both parts have the same compliance certifications?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical MSL 1 (Unlimited) moisture sensitivity ratings.
