Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX7DBF3-1000.0000C are identified based on the following critical parameters that determine functional compatibility:

Mandatory Matching Parameters:

• Frequency: 1 GHz
• Output Type: LVDS
• Function: Enable/Disable
• Package / Case: 8-SMD, No Lead
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C ~ 85°C
• Frequency Stability: ±25ppm

Allowable Variation Parameters:

• Voltage - Supply: Substitutes may operate at different supply voltages (1.8V or 2.5V) provided the design accommodates the voltage requirement
• Current - Supply (Max): Substitutes with equivalent or lower maximum supply current are acceptable

The substitute parts identified maintain identical mechanical dimensions, package specifications, and electrical performance characteristics while allowing for supply voltage flexibility based on system design requirements.

Parameter Comparison

Engineering Selection Recommendations

AX7DCF1-1000.0000C (MFR Recommended Substitute): This part is the manufacturer-recommended alternative, maintaining all critical electrical and mechanical specifications. The primary difference is the reduced supply voltage requirement of 1.8V versus 2.5V. This substitute is suitable for designs where lower supply voltage operation is compatible with system architecture. ROHS3 compliance and MSL 1 rating ensure equivalent environmental and regulatory compliance.

AX7DBF1-1000.0000C (Parametric Equivalent): This part provides parametric equivalence with identical supply voltage (2.5V) to the main part, differing only in the specific part number designation within the ClearClock™ AX7 series. All electrical performance, mechanical dimensions, and compliance certifications remain unchanged. This substitute is appropriate for direct replacement in existing designs without voltage supply modifications.

Both substitutes maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can AX7DCF1-1000.0000C be used as a direct replacement for AX7DBF3-1000.0000C?

A: AX7DCF1-1000.0000C is functionally equivalent with one critical difference: it operates at 1.8V supply voltage instead of 2.5V. Direct replacement is possible only if the system power supply can accommodate 1.8V operation. All other electrical and mechanical parameters are identical.

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

A: AX7DCF1-1000.0000C (MFR Recommended) operates at 1.8V supply voltage. AX7DBF1-1000.0000C (Parametric Equivalent) operates at 2.5V supply voltage, matching the original part. Both maintain identical frequency, output type, package, and performance specifications.

Q: Are the package dimensions identical across all three parts?

A: Yes. All three parts use the 8-SMD, No Lead package with dimensions of 0.276" L x 0.197" W (7.00mm x 5.00mm) and maximum seated height of 0.075" (1.90mm). PCB layout and footprint compatibility are maintained across all substitutes.

Q: Do the substitute parts have the same frequency stability?

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

Q: Are there any compliance or regulatory differences between the main part and substitutes?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance is equivalent.
