Substitute Part Grouping Explanation

Substitute parts for the AX5DAF2-400.0000C are identified based on strict parametric equivalence across the following critical criteria:

Frequency matching at 400 MHz ensures direct functional replacement in clock distribution and timing applications. Output type equivalence (LVDS) maintains signal integrity and compatibility with receiving circuitry. Supply voltage equivalence at 3.3V ensures proper biasing and power delivery without circuit modification. Enable/Disable function equivalence preserves power management capabilities. Frequency stability at ±20ppm maintains timing accuracy requirements. Operating temperature range coverage from -40°C to 85°C ensures environmental compatibility. Package type equivalence (8-SMD, No Lead) and physical dimensions ensure mechanical fit on printed circuit boards. RoHS3 compliance and MSL 1 rating confirm regulatory and handling compatibility.

Parameter Comparison

Engineering Selection Recommendations

The AX5DAF1-400.0000C serves as a parametric equivalent substitute for the AX5DAF2-400.0000C. Both parts are discontinued at DiGi Electronics and share identical electrical and mechanical specifications across all critical parameters. Selection between these parts should be based on current inventory availability and procurement lead times, as both meet the same regulatory compliance requirements (ROHS3 Compliant, REACH Unaffected) and handling specifications (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can the AX5DAF1-400.0000C directly replace the AX5DAF2-400.0000C in existing designs?

A: Yes. Both parts are parametrically equivalent across frequency, output type, supply voltage, function, frequency stability, operating temperature range, current specifications, package type, and physical dimensions. No circuit modifications are required.

Q: Are there differences in the part numbers that affect compatibility?

A: The part numbers differ only in the suffix designation (DAF2 versus DAF1). All other specifications, including the 400 MHz frequency and LVDS output, are identical. The suffix does not indicate functional or electrical differences relevant to substitution.

Q: What are the critical parameters for substitution compatibility?

A: Frequency (400 MHz), output type (LVDS), supply voltage (3.3V), enable/disable function, frequency stability (±20ppm), operating temperature range (-40°C to 85°C), and package type (8-SMD, No Lead) must all match for direct substitution.

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

A: Yes. Both parts use identical 8-SMD, No Lead packaging with matching dimensions (5.00mm x 3.20mm x 1.50mm maximum height). MSL 1 rating indicates unlimited shelf life under standard storage conditions, ensuring consistent handling requirements.

Q: What compliance certifications apply to substitute parts?

A: Both the AX5DAF2-400.0000C and AX5DAF1-400.0000C are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component procurement and use.
