Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX7MBF3-50.0000C is determined by the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 50 MHz
• Output Type: CML
• Function: Enable/Disable
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• Base Resonator: Crystal
• Type: XO (Standard)
• Mounting Type: Surface Mount
• Package Dimensions: 7.00mm x 5.00mm

Allowable Variations:

• Supply Voltage: The AX7MBF3-50.0000C operates at 2.5V. Substitute parts may operate at different voltage levels if the system design permits voltage adjustment or if the substitute is compatible with the existing power distribution network.
• Package Configuration: While the main part uses 8-SMD, No Lead, substitute parts may use 6-SMD, No Lead if pin assignments and functionality remain compatible.
• Current Consumption: Variations in supply current and disable current are acceptable within system power budget constraints.
• Physical Height: Minor variations in seated height are acceptable if the substitute fits within the PCB assembly constraints.

The 590WB50M0000DG from Skyworks Solutions Inc. qualifies as a substitute based on matching all mandatory parameters while operating at 1.8V and using a 6-SMD package configuration.

Parameter Comparison

Engineering Selection Recommendations

The 590WB50M0000DG is the manufacturer-recommended substitute for the AX7MBF3-50.0000C. Both components maintain identical frequency, output type, stability, and operating temperature specifications. The substitute is currently in active production status, ensuring long-term availability and supply chain continuity.

Key considerations for selection:

Voltage Compatibility: The substitute operates at 1.8V versus the original 2.5V. System designs must accommodate this lower voltage requirement through appropriate power supply configuration or voltage regulation adjustments.

Package Configuration: The substitute uses a 6-SMD package versus the original 8-SMD configuration. PCB layout modifications may be required to accommodate the different pin arrangement, though both packages share identical footprint dimensions of 7.00mm x 5.00mm.

Current Consumption: The substitute draws up to 110mA maximum supply current compared to 68mA for the original part. System power budget analysis is required to confirm compatibility.

Compliance: Both components meet ROHS3 compliance and carry identical Moisture Sensitivity Level ratings, ensuring equivalent environmental and regulatory compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 590WB50M0000DG directly replace the AX7MBF3-50.0000C without PCB modifications?

A: Direct replacement requires verification of three factors: (1) voltage supply compatibility at 1.8V instead of 2.5V, (2) pin assignment compatibility between 6-SMD and 8-SMD packages, and (3) power budget accommodation for increased current consumption. PCB layout review is necessary before implementation.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is determined by matching frequency (50 MHz), output type (CML), function (Enable/Disable), frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), and base resonator type (Crystal XO Standard). All substitute parts must meet these specifications.

Q: Are there differences in package footprint between the main part and substitute?

A: Both components share identical footprint dimensions of 7.00mm x 5.00mm. However, the main part uses 8-SMD configuration while the substitute uses 6-SMD configuration. Pin mapping must be verified to ensure correct signal routing on the PCB.

Q: How does the voltage difference affect system design?

A: The substitute operates at 1.8V compared to the original 2.5V. This requires either a dedicated 1.8V power supply or voltage regulation from the existing 2.5V supply. System power distribution and signal integrity analysis is necessary.

Q: What is the impact of increased current consumption in the substitute?

A: The substitute draws up to 110mA maximum supply current versus 68mA for the original part. System power budget must accommodate this 42mA increase. Thermal analysis and power supply capacity verification are required.

Q: Are both components RoHS compliant?

A: Yes, both the AX7MBF3-50.0000C and 590WB50M0000DG are ROHS3 compliant with identical Moisture Sensitivity Level ratings of 1 (Unlimited), ensuring equivalent environmental compliance.
