Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX7DBF1-320.0000C is determined by the following critical parameters:

• Frequency: 320 MHz (exact match required)
• Output: LVDS (electrical interface requirement)
• Supply Voltage: 2.5V (power compatibility)
• Function: Enable/Disable (operational feature)
• Frequency Stability: ±25ppm (timing accuracy)
• Operating Temperature: -40°C ~ 85°C (environmental range)
• Mounting: Surface Mount, SMD No Lead (PCB integration)
• Physical Footprint: 7.00mm x 5.00mm (board layout compatibility)

The substitute part 591FB320M000DG from Skyworks Solutions Inc. meets all critical electrical and mechanical parameters. Package variations (8-SMD vs. 6-SMD) are acceptable provided the physical footprint and mounting type remain compatible.

Parameter Comparison

Engineering Selection Recommendations

The 591FB320M000DG from Skyworks Solutions Inc. is a direct substitute for the discontinued AX7DBF1-320.0000C. Both components share identical electrical specifications, frequency accuracy, and operating parameters. The Skyworks part carries Active product status, ensuring continued availability and supply chain support.

Current consumption ratings for the Skyworks substitute are higher than the original part (100mA vs. 70mA maximum supply current), which is acceptable in applications where the original design margin accommodates this difference. The physical footprint remains identical at 7.00mm x 5.00mm, and the lower seated height (1.80mm vs. 1.90mm) presents no compatibility issues.

Both parts maintain ROHS3 compliance and identical export classifications (EAR99, HTSUS 8542.39.0001), supporting regulatory and procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the 591FB320M000DG replace the AX7DBF1-320.0000C directly on the PCB?

A: Yes. Both parts share the same 7.00mm x 5.00mm footprint and SMD, No Lead package type. The 6-SMD configuration of the Skyworks part is compatible with the 8-SMD pad layout of the original design.

Q: What are the key differences between these parts?

A: The primary differences are manufacturer (Abracon vs. Skyworks), product status (discontinued vs. active), and maximum current ratings. The Skyworks part draws up to 100mA compared to 70mA for the original. All electrical specifications, frequency, output type, and operating parameters are identical.

Q: Are there any compliance or certification concerns with substitution?

A: No. Both parts are ROHS3 compliant, carry identical ECCN and HTSUS classifications, and maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Does the lower seated height of the substitute part affect board assembly?

A: No. The 1.80mm seated height of the Skyworks part is lower than the original 1.90mm, which presents no clearance or assembly issues.

Q: Is the higher current consumption of the substitute part a concern?

A: The higher maximum current ratings (100mA supply, 75mA disable) of the Skyworks part are compatible with designs that accommodated the original 70mA and 65mA specifications. Verify that power supply and circuit design margins support this difference.
