Substitute Part Grouping Explanation

Substitution for the AX5DAF4-400.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 400 MHz (exact match required)
• Output Configuration: 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)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±20ppm (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 parts are discontinued at DiGi Electronics and carry identical compliance certifications (ROHS3, REACH Unaffected). Selection between AX5DAF4-400.0000C and AX5DAF1-400.0000C should be based on current inventory availability. The AX5DAF1-400.0000C currently maintains 766 units in stock compared to 799 units for the primary part, making either option viable for procurement. Both components meet the same regulatory and environmental requirements for deployment in applications requiring 400 MHz LVDS oscillation at 3.3V with Enable/Disable control.

Frequently Asked Questions (FAQ)

Q: Can the AX5DAF1-400.0000C directly replace the AX5DAF4-400.0000C?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output characteristics, package dimensions, and compliance ratings. No circuit modifications are required for substitution.

Q: Are there any differences in the 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 (5.00mm x 3.20mm x 1.50mm max height).

Q: What is the significance of the part number suffix difference (DAF4 vs. DAF1)?

A: The suffix variation indicates different internal configurations within the ClearClock™ AX5 series. However, all critical electrical and mechanical parameters remain identical, supporting full substitution.

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

A: Yes. Both parts operate across -40°C to 85°C, meeting identical thermal requirements.

Q: Do both parts have the same moisture sensitivity classification?

A: Yes. Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Which part should be selected if both are available?

A: Selection should be based on current inventory availability and lead time requirements. Both parts are functionally and mechanically equivalent for all applications requiring 400 MHz LVDS oscillation at 3.3V.
