Substitute Part Grouping Explanation

Substitution eligibility for the AX7DCF3-2100.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 2.1 GHz (exact match required)
• Output Configuration: LVDS (exact match required)
• Supply Voltage: 1.8V (exact match required)
• Enable/Disable Function: Present (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Package Type: 8-SMD, No Lead (exact match required)
• Physical Dimensions: 7.00mm x 5.00mm (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The AX7DCF1-2100.0000C qualifies as a parametric equivalent based on identical specifications across all critical electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The AX7DCF1-2100.0000C serves as a direct parametric equivalent to the AX7DCF3-2100.0000C. Both parts are discontinued at DiGi Electronics and share identical electrical specifications, mechanical dimensions, and regulatory compliance certifications. Selection between these parts depends on availability and inventory status rather than technical differentiation. Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Current inventory availability should be the primary factor in component selection for procurement purposes.

Frequently Asked Questions (FAQ)

Q: Can the AX7DCF1-2100.0000C be used as a direct replacement for the AX7DCF3-2100.0000C?

A: Yes. The AX7DCF1-2100.0000C is a parametric equivalent with identical frequency, output type, supply voltage, enable/disable function, frequency stability, operating temperature range, supply current specifications, package type, and physical dimensions. No circuit modifications are required.

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

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Regulatory status is identical.

Q: What is the significance of the different part number designations (DCF3 vs. DCF1)?

A: The part number variation reflects internal Abracon manufacturing or revision designations. From an engineering standpoint, both parts meet identical parametric specifications and are functionally interchangeable.

Q: Are the physical dimensions and package footprints identical?

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

Q: What is the moisture sensitivity level for these oscillators?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.
