Substitute Part Grouping Explanation

Substitution for the AX7DBF1-148.5000C is determined by strict equivalence across the following critical parameters:

• Frequency: 148.5 MHz (exact match required)
• Output: LVDS (signal type compatibility)
• Supply Voltage: 2.5V (electrical compatibility)
• Function: Enable/Disable (operational feature match)
• Frequency Stability: ±25ppm (timing accuracy)
• Operating Temperature: -40°C ~ 85°C (thermal range)
• Package: 8-SMD, No Lead (physical and electrical footprint)
• Dimensions: 7.00mm x 5.00mm (PCB layout compatibility)

The substitute part AX7DBF3-148.5000C meets all these criteria, establishing it as a parametric equivalent within the ClearClock™ AX7 series.

Parameter Comparison

Engineering Selection Recommendations

The AX7DBF3-148.5000C is a direct parametric equivalent to the AX7DBF1-148.5000C. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. The substitute part maintains identical electrical specifications, thermal performance, and physical footprint characteristics. Selection between these parts is based on availability and inventory status rather than technical differentiation. Both parts are discontinued at DiGi Electronics, requiring sourcing through alternative distribution channels or inventory management strategies.

Frequently Asked Questions (FAQ)

Q: Can AX7DBF3-148.5000C be used as a direct replacement for AX7DBF1-148.5000C?

A: Yes. The AX7DBF3-148.5000C is a parametric equivalent with identical frequency, output type, supply voltage, package dimensions, and all electrical specifications. Direct substitution is supported without circuit modification.

Q: Are there any differences in the pin configuration or footprint?

A: No. Both parts use the same 8-SMD, No Lead package with identical 7.00mm x 5.00mm dimensions and 1.90mm maximum height. PCB layout and assembly processes remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both AX7DBF1-148.5000C and AX7DBF3-148.5000C are ROHS3 compliant, REACH unaffected, and carry the same ECCN classification (EAR99).

Q: What is the difference between these two part numbers?

A: The provided data indicates both parts are parametrically identical across all specified electrical and mechanical parameters. The difference in part number designation reflects internal Abracon LLC product line management but does not indicate functional or performance differentiation.

Q: Are there alternative manufacturers producing equivalent 148.5 MHz LVDS oscillators?

A: The provided data contains only Abracon LLC parts. Equivalent parts from other manufacturers would require separate parametric analysis against the specified criteria.
