Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX7DAF2-1500.0000C 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 (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Base Resonator: Crystal (exact match required)
• Type: XO (Standard) (exact match required)
• Function: Enable/Disable (exact match required)

The AX7DBF1-1500.0000C qualifies as a substitute part because it maintains identical specifications across all critical parameters except supply voltage, which differs at 2.5V versus 3.3V. This voltage difference represents a design trade-off that may be acceptable depending on circuit requirements and power supply architecture.

Parameter Comparison

Engineering Selection Recommendations

The AX7DBF1-1500.0000C serves as a direct substitute for the discontinued AX7DAF2-1500.0000C when supply voltage compatibility permits. Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring equivalent environmental and regulatory standing. The primary consideration for substitution is the 2.5V versus 3.3V supply voltage differential. Selection of the substitute part requires confirmation that the circuit design accommodates 2.5V operation or that power supply modification is feasible. Both parts share identical mechanical footprints, thermal characteristics, and frequency performance specifications, enabling straightforward PCB-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can the AX7DBF1-1500.0000C replace the AX7DAF2-1500.0000C in existing designs?

A: Direct substitution is possible only if the circuit design supports 2.5V supply voltage operation. The substitute part maintains identical frequency, output type, package, and thermal specifications. If the original design requires 3.3V operation, circuit modification or alternative sourcing is necessary.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 8-SMD, No Lead package with 7.00mm x 5.00mm footprint and 1.90mm maximum seated height. PCB layout and assembly processes require no modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the AX7DAF2-1500.0000C and AX7DBF1-1500.0000C are ROHS3 compliant with MSL 1 (Unlimited) rating, ensuring equivalent environmental and regulatory compliance.

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.

Q: Are there differences in current consumption between these parts?

A: No. Both parts specify 70mA maximum supply current and 65mA maximum disable current, providing identical power consumption characteristics.
