Substitute Part Grouping Explanation

Substitution for the AX7DAF1-106.2500C is determined by strict equivalence across the following critical parameters:

• Frequency: 106.25 MHz (exact match required)
• Output: LVDS (differential signaling standard)
• Supply Voltage: 3.3V
• Function: Enable/Disable capability
• Frequency Stability: ±25ppm
• Operating Temperature: -40°C ~ 85°C
• Package: 8-SMD, No Lead with 7.00mm x 5.00mm footprint
• Compliance: ROHS3 and MSL 1 rating

The ODEMDLVTNF-106.250000 from Taitien meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The ODEMDLVTNF-106.250000 is a qualified substitute for the AX7DAF1-106.2500C based on electrical and mechanical parameter equivalence. Both parts meet ROHS3 compliance and MSL 1 moisture sensitivity requirements. The substitute part maintains active product status, ensuring continued availability for procurement and support.

The Taitien oscillator exhibits higher maximum supply current specifications (90mA vs. 70mA) and higher disable current (110mA vs. 65mA). These differences do not preclude substitution but should be evaluated within the context of the application's power budget and thermal management design.

The substitute part's maximum seated height of 1.85mm is 0.05mm lower than the original, presenting no clearance concerns for standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the ODEMDLVTNF-106.250000 be used as a direct replacement for the AX7DAF1-106.2500C?

A: Yes. Both oscillators share identical frequency (106.25 MHz), output type (LVDS), supply voltage (3.3V), function (Enable/Disable), frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), and package footprint (7.00mm x 5.00mm, 8-SMD, No Lead). Electrical and mechanical compatibility is established.

Q: What are the differences in current consumption between these parts?

A: The Taitien substitute draws a maximum of 90mA during operation compared to 70mA for the Abracon original. In disable mode, the Taitien part draws 110mA versus 65mA for the original. These differences should be factored into power supply and thermal design calculations.

Q: Are both parts compliant with environmental and regulatory standards?

A: Yes. Both the AX7DAF1-106.2500C and ODEMDLVTNF-106.250000 are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. Both are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Q: Does the height difference between the two parts affect PCB assembly?

A: No. The substitute part's maximum seated height of 1.85mm is 0.05mm lower than the original 1.90mm. This minor difference does not impact standard surface mount assembly processes or PCB clearance requirements.

Q: Why is the original part discontinued?

A: The AX7DAF1-106.2500C is discontinued at DiGi Electronics. The ODEMDLVTNF-106.250000 maintains active product status and is available for new designs and ongoing production support.
