Substitute Part Grouping Explanation

Substitute parts for the AX7DAF2-125.0000C are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitutability:

Critical Parameters for Substitution:

• Frequency: 125 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Package Type: 8-SMD, No Lead (exact match required)
• Package Dimensions: 7.00mm x 5.00mm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±25ppm (exact match required)

Allowable Variations:

• Current Supply (Max): Substitute may have higher current consumption if system design accommodates
• Maximum Height: Substitute may have different seated height within PCB assembly constraints
• Current Supply (Disable): Substitute may have different disable current if within system power budget

Parameter Comparison

Engineering Selection Recommendations

AX7DAF1-125.0000C (Abracon LLC): This part is a parametric equivalent within the same ClearClock™ AX7 series. It matches all critical electrical and mechanical parameters with the main part. Both parts share identical current specifications (70mA max supply, 65mA max disable). This substitute maintains design continuity within the Abracon product line. Product status is discontinued at DiGi Electronics, consistent with the main part.

ODEMDLVTNF-125.000000 (Taitien): This part meets all critical substitution criteria with identical frequency, output type, supply voltage, function, package type, and dimensions. The maximum height is 0.05mm lower (1.85mm vs 1.90mm), which is within typical PCB assembly tolerances. Current consumption is higher (90mA max supply, 110mA max disable) compared to the main part. This substitute is currently active in production. System power budget must accommodate the increased current draw. ROHS3 compliance and MSL 1 rating match the main part.

Frequently Asked Questions (FAQ)

Q: Can ODEMDLVTNF-125.000000 be used as a direct replacement for AX7DAF2-125.0000C?

A: Yes, from an electrical and mechanical standpoint. The Taitien part meets all critical parameters: 125 MHz frequency, LVDS output, 3.3V supply, Enable/Disable function, and identical package dimensions. The higher current consumption (90mA vs 70mA) must be evaluated against your system's power delivery capability. The 0.05mm height difference is within standard PCB assembly tolerances.

Q: What is the difference between AX7DAF2-125.0000C and AX7DAF1-125.0000C?

A: Both parts are from Abracon's ClearClock™ AX7 series with identical electrical specifications and current ratings. The primary difference is the part number designation within the same product line. Both are discontinued at DiGi Electronics.

Q: Are there any compliance or certification differences between the substitutes?

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

Q: What should I consider when selecting between the two substitutes?

A: If the Abracon AX7DAF1-125.0000C is available, it provides identical current specifications and maintains design continuity within the same series. If only the Taitien ODEMDLVTNF-125.000000 is available, confirm that your power supply can deliver the additional 20mA during normal operation and 45mA during disable mode.

Q: Is the 0.05mm height difference between parts significant?

A: The Taitien part is 0.05mm shorter (1.85mm vs 1.90mm). This difference is negligible for standard PCB assembly and does not affect component placement or clearance in typical designs.
