Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX7DAF4-360.0000C is determined by strict equivalence across the following critical parameters:

• Frequency: 360 MHz (exact match required)
• Output: LVDS (electrical interface compatibility)
• Supply Voltage: 3.3V (power supply compatibility)
• Function: Enable/Disable (control interface compatibility)
• Frequency Stability: ±25ppm (timing accuracy specification)
• Operating Temperature: -40°C ~ 85°C (environmental operating range)
• Mounting: Surface Mount (assembly process compatibility)
• Footprint: 7.00mm x 5.00mm (PCB layout compatibility)

The substitute part 591BB360M000DG from Skyworks Solutions Inc. meets all critical electrical and mechanical parameters. Package differences (6-SMD vs. 8-SMD) and minor variations in supply current and seated height do not affect functional substitution when footprint compatibility is maintained.

Engineering Selection Recommendations

The 591BB360M000DG from Skyworks Solutions Inc. is the qualified substitute for the discontinued AX7DAF4-360.0000C. Selection is based on:

• Active product status: The substitute remains in active production, ensuring long-term availability and supply chain continuity.
• Electrical equivalence: All critical parameters including frequency, output type, supply voltage, function, and frequency stability are identical.
• Mechanical compatibility: Identical footprint dimensions (7.00mm x 5.00mm) and compatible seated heights enable direct PCB layout reuse.
• Environmental compliance: Both parts meet MSL 1 (Unlimited) moisture sensitivity and operate across the same temperature range.
• Supply current differences: The substitute exhibits higher maximum supply current (100mA vs. 70mA) and disable current (75mA vs. 65mA). These differences are compatible with standard 3.3V power distribution designs.
• Package configuration: The substitute uses a 6-SMD package versus the original 8-SMD package. PCB layout and assembly process compatibility must be confirmed for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the 591BB360M000DG be used as a direct replacement for the AX7DAF4-360.0000C?

A: Yes, the 591BB360M000DG is electrically and mechanically compatible. Both devices operate at 360 MHz with LVDS output, 3.3V supply, enable/disable function, and identical frequency stability. The footprint dimensions are identical. PCB layout reuse is possible; however, the package configuration differs (6-SMD vs. 8-SMD), requiring assembly process verification.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Abracon vs. Skyworks), package configuration (8-SMD vs. 6-SMD), and supply current specifications. The substitute exhibits higher maximum supply current (100mA vs. 70mA) and disable current (75mA vs. 65mA). Seated height is slightly lower (1.80mm vs. 1.90mm). All electrical performance parameters are identical.

Q: Does the higher supply current of the substitute affect circuit design?

A: No. The substitute's higher maximum supply current (100mA) is compatible with standard 3.3V power distribution designs. The actual operating current depends on the specific application and frequency output load. Higher maximum ratings do not require circuit redesign.

Q: Are there any compliance or certification differences?

A: Both parts are MSL 1 (Unlimited) and operate across -40°C to 85°C. The original part is specified as ROHS3 Compliant. Compliance documentation for the substitute should be obtained from Skyworks Solutions Inc. for regulatory requirements specific to your application.

Q: What impact does the package change (8-SMD to 6-SMD) have?

A: The package configuration change affects assembly process compatibility and PCB footprint implementation. While the overall dimensions (7.00mm x 5.00mm) are identical, the internal lead configuration differs. Assembly equipment and solder reflow profiles must be compatible with the 6-SMD package. Consult assembly documentation and Skyworks datasheets for specific requirements.
