Substitute Part Grouping Explanation

Substitution eligibility for the AX7DAF1-1500.0000C is determined by the following critical parameters:

• Frequency: 1.5 GHz (exact match required)
• Output Type: LVDS (exact match required)
• Package / Case: 8-SMD, No Lead (exact match required)
• Physical Dimensions: 7.00mm x 5.00mm (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Function: Enable/Disable (exact match required)
• Series: ClearClock™ AX7 (exact match required)

The AX7DBF1-1500.0000C qualifies as a substitute part because it maintains identical specifications across all critical parameters except for supply voltage, which differs at 2.5V versus the original 3.3V specification.

Parameter Comparison

Engineering Selection Recommendations

The AX7DBF1-1500.0000C serves as a manufacturer-recommended substitute for the AX7DAF1-1500.0000C. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring equivalent environmental and regulatory performance.

The primary design consideration is the supply voltage differential: the substitute operates at 2.5V while the original operates at 3.3V. This difference requires verification that the receiving circuit can accommodate the lower supply voltage specification. Both parts are discontinued at DiGi Electronics, indicating limited ongoing availability through standard distribution channels.

Current consumption specifications remain identical across both parts (70mA maximum supply current, 65mA maximum disable current), and frequency stability, operating temperature range, and physical package dimensions are fully matched.

Frequently Asked Questions (FAQ)

Q: Can the AX7DBF1-1500.0000C directly replace the AX7DAF1-1500.0000C in existing designs?

A: Direct replacement requires circuit-level verification. The substitute operates at 2.5V supply voltage versus the original 3.3V specification. If the receiving circuit is designed exclusively for 3.3V operation, the lower supply voltage of the substitute may not be compatible. Confirm that the circuit design supports 2.5V oscillator operation before substitution.

Q: Are the physical packages identical between these parts?

A: Yes. Both parts use the 8-SMD, No Lead package with identical dimensions of 7.00mm x 5.00mm and maximum seated height of 1.90mm. PCB footprints and assembly processes are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the AX7DAF1-1500.0000C and AX7DBF1-1500.0000C are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance is equivalent.

Q: What is the frequency stability specification for both parts?

A: Both parts maintain ±25ppm frequency stability across the -40°C ~ 85°C operating temperature range, ensuring equivalent timing precision for applications requiring 1.5 GHz LVDS output.

Q: Are there inventory differences between these parts?

A: The AX7DAF1-1500.0000C has 1029 pieces in stock, while the AX7DBF1-1500.0000C has 718 pieces in stock. Both are listed as discontinued at DiGi Electronics, indicating that current inventory represents remaining stock with no ongoing production.
