Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX7DAF4-200.0000C are identified based on strict electrical and mechanical parameter matching. The critical parameters that determine substitutability are:

• Frequency: 200 MHz (exact match required)
• Output: 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: -40°C ~ 85°C (exact match required)
• Package: 8-SMD, No Lead (exact match required)
• Package Dimensions: 0.276" L x 0.197" W / 7.00mm x 5.00mm (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• MSL Rating: 1 (Unlimited) (exact match required)

Parts meeting all these criteria are classified as direct substitutes. Parametric equivalents within the same manufacturer series that share identical electrical specifications but differ only in internal design variants are also listed.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the AX7DAF4-200.0000C, the ODEMDLVTNF-200.000000 from Taitien is the primary direct substitute. This part maintains all critical electrical and mechanical parameters while offering active product status and current availability. Both parts are ROHS3 compliant and carry MSL 1 ratings, ensuring compatibility with standard manufacturing and storage protocols.

The AX7DAF1-200.0000C and AX7DAF3-200.0000C are parametric equivalents within the Abracon ClearClock™ AX7 series. These parts share identical electrical specifications and package dimensions with the main part, differing only in internal design variants. However, both are also discontinued at DiGi Electronics, limiting their utility for new procurement.

Current supply considerations favor the ODEMDLVTNF-200.000000, which shows 1034 pieces in stock compared to the main part's 964 pieces. The Taitien substitute exhibits slightly higher maximum supply current values (90mA active, 110mA disabled) compared to the Abracon parts (70mA active, 65mA disabled), which should be evaluated within the context of specific circuit design margins.

Frequently Asked Questions (FAQ)

Q: Can the ODEMDLVTNF-200.000000 be used as a direct replacement for the AX7DAF4-200.0000C?

A: Yes. The ODEMDLVTNF-200.000000 meets all critical electrical and mechanical specifications: 200 MHz frequency, LVDS output, 3.3V supply, Enable/Disable function, ±25ppm stability, -40°C to 85°C operating range, and 8-SMD No Lead package with identical footprint dimensions. Both parts are ROHS3 compliant with MSL 1 ratings.

Q: What is the difference between the direct substitute and parametric equivalents?

A: The ODEMDLVTNF-200.000000 is a direct substitute from a different manufacturer (Taitien) with active product status and current availability. The AX7DAF1-200.0000C and AX7DAF3-200.0000C are parametric equivalents from the same manufacturer (Abracon) with identical electrical specifications but different internal design variants. Both parametric equivalents are discontinued at DiGi Electronics.

Q: Are there any differences in current consumption between these parts?

A: The ODEMDLVTNF-200.000000 has higher maximum supply current specifications (90mA active, 110mA disabled) compared to the AX7DAF4-200.0000C (70mA active, 65mA disabled). Circuit designs must account for this difference in power supply capacity and thermal management.

Q: Do all substitute parts have the same package height?

A: The ODEMDLVTNF-200.000000 has a maximum seated height of 0.073" (1.85mm), while the AX7DAF4-200.0000C and its parametric equivalents have 0.075" (1.90mm). This 0.002" difference is within typical PCB assembly tolerances but should be verified for applications with strict height constraints.

Q: Are compliance certifications identical across all parts?

A: Yes. All parts listed are ROHS3 compliant, carry REACH Unaffected status, and have MSL 1 (Unlimited) moisture sensitivity ratings. All parts are classified under ECCN EAR99 for export control purposes.
