Substitute Part Grouping Explanation

Substitute parts for the AX7DCF3-1000.0000C are identified based on strict parametric equivalence across the following critical criteria:

• Frequency: 1 GHz
• Output Type: LVDS
• Supply Voltage: 1.8V
• Function: Enable/Disable
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• 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)
• Current - Supply (Max): 70mA
• Current - Supply (Disable) (Max): 65mA
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The AX7DCF1-1000.0000C is a direct parametric equivalent to the AX7DCF3-1000.0000C. Both parts are manufactured by Abracon LLC within the ClearClock™ AX7 series and share identical electrical, mechanical, and environmental specifications. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for current applications.

Given that both parts are discontinued at DiGi Electronics, component selection should be based on current inventory availability. The AX7DCF3-1000.0000C currently has 1101 pieces in stock, while the AX7DCF1-1000.0000C has 778 pieces available. Either part is suitable for direct substitution in applications requiring a 1 GHz LVDS oscillator with 1.8V supply and enable/disable functionality.

Frequently Asked Questions (FAQ)

Q: Can the AX7DCF1-1000.0000C replace the AX7DCF3-1000.0000C in existing designs?

A: Yes. Both parts are parametric equivalents with identical frequency, output type, supply voltage, function, frequency stability, operating temperature range, package type, physical dimensions, and current specifications. Direct substitution is supported without design modification.

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

A: No. Both parts carry identical RoHS3 compliance and REACH unaffected status. Moisture sensitivity level is 1 (Unlimited) for both parts, indicating no special handling requirements.

Q: What is the significance of the different part numbers (AX7DCF3 vs. AX7DCF1)?

A: The part number variation reflects internal Abracon LLC product line differentiation. From an engineering standpoint, both parts meet identical parametric specifications and are functionally interchangeable.

Q: Which part should be selected if both are available?

A: Selection should be based on procurement availability and lead time requirements. The AX7DCF3-1000.0000C currently has higher inventory (1101 pcs vs. 778 pcs). Both parts are discontinued at DiGi Electronics, so availability through alternative distributors should be verified for long-term supply planning.

Q: Are these parts suitable for high-reliability applications?

A: Both parts meet ROHS3 compliance and carry MSL 1 rating, indicating compatibility with standard manufacturing processes. Specific high-reliability requirements should be evaluated against application-specific standards and certifications.
