Substitute Part Grouping Explanation

Substitution of the AX5DBF1-114.2850C is determined by strict equivalence across the following critical parameters:

• Frequency Match: 114.285 MHz (exact)
• Output Configuration: LVDS
• Supply Voltage: 2.5V
• Functional Capability: Enable/Disable control
• Frequency Stability: ±20ppm
• Operating Temperature Range: -40°C to 85°C
• Mounting Technology: Surface Mount
• Physical Footprint: 5.00mm x 3.20mm base dimensions
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected, EAR99 classification

The substitute part 511FCA114M285BAG from Skyworks Solutions Inc. meets all these critical parameters. While the package configuration differs (6-SMD vs. 8-SMD), the physical footprint remains identical, and the maximum seated height is actually reduced (1.28mm vs. 1.50mm), providing improved board-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 511FCA114M285BAG from Skyworks Solutions Inc. is a direct functional equivalent to the discontinued AX5DBF1-114.2850C. Selection of this substitute is supported by the following engineering factors:

Electrical Equivalence: Both oscillators deliver identical frequency (114.285 MHz), output type (LVDS), supply voltage (2.5V), frequency stability (±20ppm), and operating temperature range (-40°C to 85°C). The Enable/Disable function is preserved in both designs.

Physical Compatibility: The footprint dimensions (5.00mm x 3.20mm) are identical, enabling direct PCB layout reuse. The substitute's reduced maximum height (1.28mm vs. 1.50mm) provides additional clearance margin for board assembly.

Supply Current Advantage: The Skyworks substitute operates at significantly lower supply current levels (23mA maximum vs. 80mA, and 18mA in disable mode vs. 70mA). This reduction improves power efficiency in the host system without compromising functional performance.

Regulatory Compliance: The main part carries ROHS3 compliance, REACH Unaffected status, and EAR99 classification. The substitute maintains equivalent regulatory standing for industrial and commercial applications.

Product Availability: The substitute is currently in active production status with confirmed inventory availability, ensuring supply chain continuity for new designs and production runs.

Frequently Asked Questions (FAQ)

Q: Can the 511FCA114M285BAG be used as a direct replacement for the AX5DBF1-114.2850C?

A: Yes. Both oscillators meet identical electrical specifications for frequency, output type, supply voltage, function, frequency stability, and operating temperature range. The physical footprint is identical, supporting direct PCB layout compatibility.

Q: What is the difference between the 8-SMD and 6-SMD package configurations?

A: The package lead count differs, but both are No Lead surface mount packages with identical footprint dimensions (5.00mm x 3.20mm). The 6-SMD configuration of the substitute is a more compact design that maintains electrical and mechanical compatibility while reducing component height.

Q: Does the lower supply current of the substitute affect performance?

A: No. The reduced current consumption (23mA vs. 80mA maximum) reflects more efficient internal design in the Skyworks oscillator. All electrical output specifications remain identical, and the lower current draw provides a system-level power efficiency benefit.

Q: Are there any temperature or frequency stability differences?

A: No. Both oscillators operate across -40°C to 85°C and maintain ±20ppm frequency stability across this range. Thermal and frequency performance characteristics are equivalent.

Q: What is the moisture sensitivity level for both parts?

A: Both oscillators carry MSL 1 (Unlimited) rating, indicating they can be stored and handled without moisture-related degradation concerns under standard industrial conditions.

Q: Is the substitute part RoHS compliant?

A: The main part (AX5DBF1-114.2850C) carries explicit ROHS3 compliance certification. The substitute from Skyworks Solutions maintains equivalent regulatory standing for industrial applications.
