Substitute Part Grouping Explanation

Substitute parts for the AX7DBF2-2100.0000C are identified based on the following critical parameters that determine functional compatibility:

Mandatory Matching Parameters:

• Frequency: 2.1 GHz
• Output Type: LVDS
• Function: Enable/Disable
• Package / Case: 8-SMD, No Lead
• Physical Dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm)
• Height - Seated (Max): 0.075" (1.90mm)
• Operating Temperature Range: -40°C ~ 85°C
• Frequency Stability: ±25ppm

Allowable Variation Parameters:

• Voltage - Supply: Alternative voltage ratings within the same series
• Current - Supply (Max): Equivalent or lower current consumption
• Current - Supply (Disable) (Max): Equivalent or lower current consumption

Substitute parts maintain identical mechanical compatibility, electrical output characteristics, and thermal performance while allowing for supply voltage variations within the ClearClock™ AX7 series design envelope.

Engineering Selection Recommendations

AX7DCF1-2100.0000C (MFR Recommended Substitute)

This part is designated as the manufacturer-recommended substitute. It maintains all critical electrical and mechanical parameters identical to the AX7DBF2-2100.0000C with the exception of supply voltage, which operates at 1.8V instead of 2.5V. Selection of this part requires circuit-level verification that the 1.8V supply voltage is compatible with the application's power distribution architecture. Current consumption specifications remain equivalent. ROHS3 compliance and MSL rating are maintained.

AX7DBF1-2100.0000C (Parametric Equivalent)

This part provides parametric equivalence with identical supply voltage (2.5V) to the main part. All electrical performance characteristics, mechanical dimensions, and compliance certifications are matched. This part presents the lowest integration risk for direct substitution in existing designs.

Both substitute parts are discontinued at DiGi Electronics, consistent with the main part status. Selection between these options depends on circuit power supply architecture and voltage rail availability.

Frequently Asked Questions (FAQ)

Q: Can AX7DCF1-2100.0000C be used as a direct replacement for AX7DBF2-2100.0000C?

A: AX7DCF1-2100.0000C is the manufacturer-recommended substitute but operates at 1.8V supply voltage versus the main part's 2.5V. Direct substitution requires verification that the application circuit can supply 1.8V to the oscillator and that downstream components accept LVDS signals from a 1.8V-supplied source.

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

A: AX7DCF1-2100.0000C (MFR Recommended) differs in supply voltage (1.8V). AX7DBF1-2100.0000C (Parametric Equivalent) maintains identical supply voltage (2.5V) to the main part. The parametric equivalent presents lower integration complexity for existing designs.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts share identical package type (8-SMD, No Lead), physical dimensions (7.00mm x 5.00mm), and height (1.90mm maximum seated height), enabling direct PCB footprint compatibility.

Q: Do supply voltage differences affect frequency stability?

A: No. All three parts maintain ±25ppm frequency stability across the -40°C ~ 85°C operating temperature range regardless of supply voltage rating.

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

A: No. All three parts are ROHS3 compliant, carry MSL rating of 1 (Unlimited), and share identical REACH and ECCN classifications.

Q: What current consumption should be expected during normal operation?

A: Maximum supply current is 70mA during enabled operation and 65mA during disabled operation for all three parts.
