Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX7DBF4-1500.0000C is determined by the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 1.5 GHz
• Output Type: LVDS
• Function: Enable/Disable
• Package Type: 8-SMD, No Lead
• Package Dimensions: 7.00mm x 5.00mm
• Operating Temperature Range: -40°C ~ 85°C
• Frequency Stability: ±25ppm

Allowable Variation Parameters:

• Supply Voltage: 2.5V (primary) or 1.8V (alternative supply voltage acceptable with circuit design consideration)
• Maximum Supply Current: 70mA (substitute must not exceed this specification)
• Maximum Disable Current: 65mA (substitute must not exceed this specification)

The substitute parts identified below maintain all mandatory parameters while offering alternative supply voltage options within the ClearClock™ AX7 series, ensuring mechanical and electrical compatibility with the original design footprint and functional requirements.

Engineering Selection Recommendations

AX7DCF1-1500.0000C (MFR Recommended Substitute): This part is designated as the manufacturer-recommended substitute. It maintains identical mechanical compatibility and all critical electrical parameters with the exception of supply voltage, which operates at 1.8V instead of 2.5V. Selection of this part requires circuit design modification to accommodate the lower supply voltage. This substitute is appropriate for new designs or redesigns where supply voltage adjustment is feasible. ROHS3 compliance and MSL 1 rating ensure regulatory and environmental compatibility.

AX7DBF1-1500.0000C (Parametric Equivalent): This part provides direct parametric equivalence to the original AX7DBF4-1500.0000C, maintaining identical supply voltage (2.5V), frequency, output type, and all electrical specifications. This substitute is appropriate for direct replacement in existing designs without circuit modification. ROHS3 compliance and MSL 1 rating ensure regulatory and environmental compatibility. This option minimizes design risk by eliminating the need for supply voltage circuit adjustments.

Both substitute parts are discontinued at DiGi Electronics, consistent with the original part status. Component selection should prioritize current inventory availability and design requirements regarding supply voltage compatibility.

Frequently Asked Questions (FAQ)

Q: Can AX7DCF1-1500.0000C be used as a direct replacement for AX7DBF4-1500.0000C?

A: AX7DCF1-1500.0000C is mechanically and functionally compatible but operates at 1.8V supply voltage instead of 2.5V. Direct substitution requires circuit design modification to provide the lower supply voltage. If the design circuit cannot accommodate 1.8V operation, this part is not suitable for direct replacement.

Q: What is the difference between the MFR Recommended and Parametric Equivalent substitutes?

A: AX7DCF1-1500.0000C (MFR Recommended) operates at 1.8V supply voltage and represents the manufacturer's alternative recommendation. AX7DBF1-1500.0000C (Parametric Equivalent) maintains the original 2.5V supply voltage and provides direct electrical equivalence without requiring circuit modification.

Q: Are all three parts mechanically identical?

A: Yes. All three parts share identical package type (8-SMD, No Lead), dimensions (7.00mm x 5.00mm), and maximum seated height (1.90mm). They are mechanically interchangeable on the PCB.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's compliance profile.

Q: What is the primary consideration when selecting between the two substitutes?

A: Supply voltage compatibility is the primary selection criterion. If the circuit design operates at 2.5V, select AX7DBF1-1500.0000C. If the circuit can accommodate 1.8V operation or is being redesigned, AX7DCF1-1500.0000C is available as the manufacturer-recommended alternative.

Q: Are frequency stability and operating temperature range identical across all three parts?

A: Yes. All three parts maintain ±25ppm frequency stability and -40°C ~ 85°C operating temperature range, ensuring consistent performance across the product family.
