Substitute Part Grouping Explanation

Substitute parts for the AX7DBF2-125.0000C are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Parameters for Substitution:

• Frequency: 125 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Supply Voltage: 2.5V (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)
• Physical Dimensions: 7.00mm x 5.00mm (exact match required)

Substitute Categories:

Direct Manufacturer Substitute: ODJMDLVTNF-125.000000 (Taitien) — Functionally equivalent across all critical electrical parameters with identical package and dimensional specifications.

Parametric Equivalent: AX7DBF1-125.0000C (Abracon LLC) — Same manufacturer series with identical electrical and mechanical specifications, differing only in internal design variant designation.

Parameter Comparison

Engineering Selection Recommendations

AX7DBF1-125.0000C (Abracon LLC): This parametric equivalent maintains identical electrical specifications and is from the same manufacturer series. Both the main part and this equivalent are discontinued at DiGi Electronics. Selection of this part preserves design consistency within the Abracon ClearClock™ AX7 product line.

ODJMDLVTNF-125.000000 (Taitien): This direct manufacturer substitute from Taitien meets all critical electrical and mechanical requirements. The part is currently active in production, providing supply continuity. Maximum supply current specifications are higher (80mA vs. 70mA), and maximum height is slightly reduced (1.85mm vs. 1.90mm), both favorable for thermal and spatial considerations. ROHS3 compliance and MSL 1 rating match the original specification.

Frequently Asked Questions (FAQ)

Q: Can ODJMDLVTNF-125.000000 be used as a direct replacement for AX7DBF2-125.0000C?

A: Yes. Both parts share identical frequency (125 MHz), output type (LVDS), supply voltage (2.5V), 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 Taitien part has higher current specifications and slightly reduced height, both compatible with the original design envelope.

Q: What is the difference between AX7DBF2-125.0000C and AX7DBF1-125.0000C?

A: Both are Abracon ClearClock™ AX7 series oscillators with identical electrical and mechanical specifications. The designation difference (DBF2 vs. DBF1) indicates internal design variants. Both parts are discontinued at DiGi Electronics.

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

A: No. All three parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: What should be considered when selecting between the two substitute options?

A: Selection depends on supply availability and design priorities. AX7DBF1-125.0000C maintains manufacturer consistency within the Abracon series. ODJMDLVTNF-125.000000 offers active production status and higher current headroom, with a marginally reduced package height.

Q: Are the physical dimensions identical across all three parts?

A: The footprint dimensions are identical (7.00mm x 5.00mm). Maximum seated height differs slightly: AX7DBF2-125.0000C and AX7DBF1-125.0000C are 1.90mm, while ODJMDLVTNF-125.000000 is 1.85mm. This difference is within typical PCB assembly tolerances and does not affect board-level compatibility.
