Substitute Part Grouping Explanation

Substitute parts for the AX7DAF3-200.0000C are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitutability:

Critical Parameters for Substitution:

• Frequency: 200 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (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)
• Package Dimensions: 7.00mm x 5.00mm (exact match required)

Parts meeting all critical parameters are classified as direct substitutes. Variations in supply current, maximum height, or packaging format (Strip vs. standard) do not disqualify substitution eligibility when all electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

ODEMDLVTNF-200.000000 (Taitien): This part is the primary substitute for the AX7DAF3-200.0000C. It meets all critical electrical and mechanical parameters with identical frequency, output type, supply voltage, function, frequency stability, operating temperature range, and package specifications. The part is currently active in production, ensuring long-term availability. Supply current specifications are higher (90mA max vs. 70mA max), which must be evaluated against circuit power budget constraints. ROHS3 compliance and MSL 1 rating match the original part.

AX7DAF1-200.0000C (Abracon LLC): This parametric equivalent maintains identical electrical specifications and package dimensions as the main part. As an Abracon LLC product within the same ClearClock™ AX7 series, it provides continuity with the original manufacturer. However, this part is also discontinued at DiGi Electronics, limiting its utility as a long-term procurement solution. Supply current characteristics are identical to the main part.

Frequently Asked Questions (FAQ)

Q: Can ODEMDLVTNF-200.000000 be used as a direct replacement for AX7DAF3-200.0000C?

A: Yes. Both parts share identical frequency (200 MHz), output type (LVDS), supply voltage (3.3V), function (Enable/Disable), frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), and package specifications (8-SMD, No Lead, 7.00mm x 5.00mm). The higher supply current rating of ODEMDLVTNF-200.000000 must be accommodated in the power supply design.

Q: What is the difference in supply current between the main part and ODEMDLVTNF-200.000000?

A: AX7DAF3-200.0000C draws a maximum of 70mA during operation and 65mA when disabled. ODEMDLVTNF-200.000000 draws a maximum of 90mA during operation and 110mA when disabled. Circuit power budgets must account for this 20mA increase during normal operation.

Q: Are there package compatibility concerns between these parts?

A: No. All three parts use identical 8-SMD, No Lead packages with 7.00mm x 5.00mm footprints. ODEMDLVTNF-200.000000 has a maximum seated height of 1.85mm compared to 1.90mm for the main part, which is within typical PCB assembly tolerances.

Q: What is the availability status of substitute parts?

A: ODEMDLVTNF-200.000000 is active in production. AX7DAF1-200.0000C is discontinued at DiGi Electronics. For ongoing procurement, ODEMDLVTNF-200.000000 is the recommended choice.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. ECCN and HTSUS classifications are consistent across all parts.
