Substitute Part Grouping Explanation

Substitution for the AX5DAF2-300.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 300 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±20ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Package Type: 8-SMD, No Lead (exact match required)
• Package Dimensions: 5.00mm x 3.20mm x 1.50mm (exact match required)
• Supply Current Specifications: 80mA max, 70mA disable (exact match required)
• Compliance: ROHS3, MSL 1 (exact match required)

The AX5DAF1-300.0000C meets all substitution criteria as a parametric equivalent within the ClearClock™ AX5 series.

Parameter Comparison

Engineering Selection Recommendations

The AX5DAF1-300.0000C is a direct parametric equivalent to the AX5DAF2-300.0000C. Both parts are discontinued at DiGi Electronics and maintain identical electrical and mechanical specifications. Selection between these parts should be based on current inventory availability and procurement lead times. Both parts carry ROHS3 compliance and MSL 1 rating, ensuring equivalent environmental and regulatory standing. No functional or performance differences exist between these oscillators when applied to circuits designed for the AX5DAF2-300.0000C.

Frequently Asked Questions (FAQ)

Q: Can the AX5DAF1-300.0000C be used as a direct replacement for the AX5DAF2-300.0000C?

A: Yes. The AX5DAF1-300.0000C is a parametric equivalent with identical frequency, output type, supply voltage, function, frequency stability, operating temperature range, current specifications, package type, and dimensions. No circuit modifications are required.

Q: Are there any differences in compliance or environmental ratings between these parts?

A: No. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. They are equivalent in regulatory and environmental standing.

Q: What determines whether a part can substitute for the AX5DAF2-300.0000C?

A: Substitution requires exact matching across all critical parameters: 300 MHz frequency, LVDS output, 3.3V supply, Enable/Disable function, ±20ppm stability, -40°C to 85°C operating range, 80mA/70mA current specifications, 8-SMD No Lead package, and 5.00mm x 3.20mm x 1.50mm dimensions.

Q: Are there other oscillators in the ClearClock™ AX5 series that could serve as alternatives?

A: Only parts matching all specified parameters can serve as direct substitutes. Oscillators with different frequencies, output types, supply voltages, or package specifications are not equivalent and would require circuit redesign.

Q: What should be considered when selecting between available substitute parts?

A: Procurement decisions should be based on current inventory levels and lead times. Both parts are functionally and electrically identical, so availability and delivery schedule are the primary selection criteria.
