Substitute Part Grouping Explanation

Substitution eligibility for the AX7MCF4-50.0000C is determined by the following critical parameters:

• Frequency: 50 MHz (exact match required)
• Output Type: CML (exact match required)
• Supply Voltage: 1.8V (exact match required)
• Function: Enable/Disable (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Base Resonator: Crystal (exact match required)
• Type: XO (Standard) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Package Dimensions: 7.00mm x 5.00mm (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The 590WB50M0000DG from Skyworks Solutions Inc. meets all substitution criteria. Variations in package configuration (6-SMD vs. 8-SMD), maximum supply current (110mA vs. 68mA), maximum disable current (75mA vs. 67mA), and maximum height (1.80mm vs. 1.90mm) are within acceptable tolerance ranges for this oscillator category and do not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

The 590WB50M0000DG is the qualified substitute for the AX7MCF4-50.0000C. The substitute part maintains active product status with Skyworks Solutions Inc., ensuring ongoing availability and supply chain continuity. Both parts are ROHS3 compliant and carry unlimited moisture sensitivity rating (MSL 1), meeting regulatory and environmental requirements.

The substitute part exhibits higher maximum supply current (110mA vs. 68mA) and maximum disable current (75mA vs. 67mA), which represents increased power consumption margins. These differences do not impact functional compatibility in applications designed for the original part's specifications. The substitute's reduced maximum height (1.80mm vs. 1.90mm) provides additional clearance margin in space-constrained designs.

Both parts are classified under ECCN EAR99 and HTSUS 8542.39.0001, maintaining consistent export and tariff classification.

Frequently Asked Questions (FAQ)

Q: Can the 590WB50M0000DG replace the AX7MCF4-50.0000C in existing designs?

A: Yes. Both parts share identical frequency (50 MHz), output type (CML), supply voltage (1.8V), function (Enable/Disable), frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), and package footprint (7.00mm x 5.00mm). The substitute meets all electrical and mechanical requirements for direct substitution.

Q: What are the differences in package configuration?

A: The original part uses an 8-SMD, No Lead package, while the substitute uses a 6-SMD, No Lead package. Both maintain identical external dimensions (7.00mm x 5.00mm) and are compatible with the same PCB footprint. The substitute's reduced lead count does not affect electrical performance or signal integrity.

Q: Why does the substitute have higher maximum supply current?

A: The 590WB50M0000DG specifies 110mA maximum supply current compared to 68mA for the AX7MCF4-50.0000C. This represents the manufacturer's maximum rated specification and does not indicate higher typical consumption. Actual operating current depends on circuit design and load conditions. Applications designed for the original part's specifications will operate within acceptable current margins with the substitute.

Q: Are there any compliance or certification differences?

A: Both parts carry MSL 1 (Unlimited) moisture sensitivity rating and are ROHS3 compliant. Both are classified as EAR99 for export control purposes. The substitute maintains equivalent regulatory and environmental compliance status.

Q: Is the substitute part currently available?

A: Yes. The 590WB50M0000DG is listed as Active product status with Skyworks Solutions Inc., ensuring ongoing procurement availability. The original AX7MCF4-50.0000C is discontinued at DiGi Electronics, making the substitute the recommended source for new orders and system support.
