Substitute Part Grouping Explanation

Substitution eligibility for the AX7DAF4-600.0000C is determined by the following critical parameters:

• Frequency: 600 MHz (exact match required)
• Output Type: LVDS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable capability (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Package Dimensions: 7.00mm x 5.00mm (exact match required)
• Mounting Type: Surface Mount (exact match required)

The substitute part 590BB600M000DG from Skyworks Solutions Inc. meets all critical electrical and mechanical parameters. Variations in package configuration (6-SMD vs. 8-SMD), maximum supply current (100mA vs. 70mA), and maximum height (1.80mm vs. 1.90mm) are within acceptable engineering tolerances for this oscillator category and do not affect functional compatibility in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The 590BB600M000DG from Skyworks Solutions Inc. is an active product with current manufacturing status, providing supply continuity for applications currently using the discontinued AX7DAF4-600.0000C. Both components share identical electrical specifications for frequency, output type, supply voltage, function, frequency stability, and operating temperature range.

The Skyworks substitute exhibits lower maximum supply current (100mA vs. 70mA) and lower maximum disable current (75mA vs. 65mA), indicating improved power efficiency. The reduced maximum height (1.80mm vs. 1.90mm) provides additional PCB layout flexibility. The 6-SMD package configuration differs from the original 8-SMD design; however, both maintain the same footprint dimensions (7.00mm x 5.00mm) and surface mount compatibility.

Both components carry MSL 1 (Unlimited) moisture sensitivity classification and comply with ECCN EAR99 and HTSUS 8542.39.0001 export classifications. Component selection should be based on PCB layout constraints, power budget requirements, and package availability in your supply chain.

Frequently Asked Questions (FAQ)

Q: Can the 590BB600M000DG directly replace the AX7DAF4-600.0000C on existing PCBs?

A: The 590BB600M000DG maintains identical footprint dimensions (7.00mm x 5.00mm) and surface mount compatibility. The difference in SMD pad count (6 vs. 8) requires PCB layout verification to confirm pad alignment and signal routing compatibility. Consult your PCB design files and the respective datasheets for pad configuration details.

Q: What is the significance of the different maximum supply currents?

A: The AX7DAF4-600.0000C specifies 70mA maximum supply current, while the 590BB600M000DG specifies 100mA. This difference reflects component design variations and does not indicate functional incompatibility. The substitute's higher current specification provides additional design margin and does not require circuit modifications if the original design accommodated the lower current rating.

Q: Are there any compliance or certification differences between these parts?

A: Both components are classified as MSL 1 (Unlimited) for moisture sensitivity and carry identical ECCN and HTSUS classifications. The AX7DAF4-600.0000C explicitly states ROHS3 compliance; the 590BB600M000DG compliance status is not specified in the provided data. Verify RoHS compliance requirements with the Skyworks datasheet before final component selection.

Q: Does the reduced maximum height of the 590BB600M000DG affect compatibility?

A: The 590BB600M000DG maximum seated height is 1.80mm compared to 1.90mm for the AX7DAF4-600.0000C. This 0.10mm reduction is within typical PCB assembly tolerances and does not create compatibility issues. The lower profile may provide additional clearance in space-constrained applications.

Q: What should I verify before implementing the substitute part?

A: Confirm PCB pad configuration compatibility with the 6-SMD package layout, verify power supply capability for the 100mA maximum current specification, and validate that your application does not depend on specific electrical characteristics beyond those listed in the parameter comparison table.
