Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX7DAF3-1500.0000C 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 footprint and 1.90mm max height (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±25ppm (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 3.3V. This voltage difference represents a design-level consideration rather than a direct pin-compatible substitution.

Parameter Comparison

Engineering Selection Recommendations

The AX7DBF1-1500.0000C serves as a functional equivalent to the AX7DAF3-1500.0000C for applications where supply voltage can be adjusted to 2.5V. Both parts maintain ROHS3 compliance and carry identical MSL ratings, ensuring equivalent environmental and regulatory standing. The substitution is valid at the component level when power supply architecture permits operation at the lower voltage specification. Both parts are discontinued at DiGi Electronics, indicating limited availability through standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Can the AX7DBF1-1500.0000C be used as a direct replacement for the AX7DAF3-1500.0000C?

A: The AX7DBF1-1500.0000C is functionally equivalent in all parameters except supply voltage. Direct substitution requires that your circuit design supports 2.5V operation instead of 3.3V. Pin configuration and package footprint are identical.

Q: What is the primary difference between these two parts?

A: The supply voltage differs: AX7DAF3-1500.0000C operates at 3.3V, while AX7DBF1-1500.0000C operates at 2.5V. All other electrical and mechanical specifications are identical.

Q: Are both parts available in the same package?

A: Yes. Both parts use the 8-SMD, No Lead package with identical physical dimensions of 7.00mm x 5.00mm and a maximum seated height of 1.90mm.

Q: Do both parts have the same frequency stability?

A: Yes. Both parts maintain ±25ppm frequency stability across the -40°C ~ 85°C operating temperature range.

Q: What is the current consumption for both parts?

A: Both parts draw a maximum of 70mA during normal operation and 65mA in disable mode.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant, carry MSL 1 (Unlimited) ratings, and are REACH unaffected.
