Substitute Part Grouping Explanation

Substitute parts for the AX7DAF1-100.0000C are qualified based on the following critical parameters that must match or remain compatible:

• Frequency: 100 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)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Substitutes are grouped into two categories: Direct Manufacturer Substitutes (alternative manufacturers) and Parametric Equivalents (same manufacturer, alternative part numbers).

Parameter Comparison

Engineering Selection Recommendations

AX7DAF3-100.0000C (Abracon LLC - Parametric Equivalent)

This part is a parametric equivalent within the same ClearClock™ AX7 series from Abracon LLC. It matches all critical electrical and mechanical parameters with the main part. Both parts share discontinued status at DiGi Electronics, indicating similar market availability constraints. Selection of this part maintains consistency within the Abracon product line and supply chain.

ODEMDLVTNF-100.000000 (Taitien - Direct Manufacturer Substitute)

This part qualifies as a direct substitute based on matching all critical parameters: frequency, output type, supply voltage, function, frequency stability, operating temperature range, package type, and package dimensions. The Taitien OD-M series part has active product status, providing better long-term availability. Current consumption specifications differ (90mA vs. 70mA maximum supply current, and 110mA vs. 65mA in disable mode), which must be evaluated against circuit power budget requirements. The maximum height is 1.85mm compared to 1.90mm, representing a 0.05mm reduction that is compatible with standard PCB assembly tolerances. RoHS3 compliance and MSL 1 rating match the original part.

Frequently Asked Questions (FAQ)

Q: Can ODEMDLVTNF-100.000000 be used as a direct replacement for AX7DAF1-100.0000C?

A: Yes, ODEMDLVTNF-100.000000 qualifies as a direct substitute. All critical electrical parameters (frequency, output type, supply voltage, function, frequency stability, and operating temperature range) and mechanical parameters (package type and dimensions) are identical. The higher current consumption specifications must be verified against circuit design limits.

Q: What is the difference in current consumption between the main part and the Taitien substitute?

A: The AX7DAF1-100.0000C specifies 70mA maximum supply current and 65mA in disable mode. The ODEMDLVTNF-100.000000 specifies 90mA maximum supply current and 110mA in disable mode. Circuit power budget analysis is required to determine if the higher current draw is acceptable for your application.

Q: Are there package dimension differences between these parts?

A: The lateral dimensions (7.00mm x 5.00mm) are identical across all three parts. The maximum seated height differs slightly: AX7DAF1-100.0000C and AX7DAF3-100.0000C are 1.90mm, while ODEMDLVTNF-100.000000 is 1.85mm. This 0.05mm difference is within standard PCB assembly tolerances and does not affect PCB layout or reflow profile requirements.

Q: What is the product status difference, and why does it matter?

A: Both Abracon parts (AX7DAF1-100.0000C and AX7DAF3-100.0000C) are discontinued at DiGi Electronics. The Taitien ODEMDLVTNF-100.000000 has active product status, indicating ongoing manufacturing and better availability for future procurement. For new designs or long-term production, the active Taitien part provides supply chain continuity.

Q: Are all three parts RoHS3 compliant?

A: Yes, all three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, meeting current environmental and regulatory requirements.
