Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX7MAF1-100.0000C is determined by strict alignment of the following electrical and mechanical parameters:

• Frequency: 100 MHz (exact match required)
• Output Configuration: CML (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)
• Mounting Type: Surface Mount (exact match required)
• Package Classification: SMD, No Lead (compatible footprint required)
• Compliance: ROHS3 Compliant, MSL 1 (Unlimited)

The substitute part 590DB100M000DG from Skyworks Solutions Inc. meets all critical electrical parameters and operates within the same environmental specifications. Package differences (6-SMD vs. 8-SMD) require PCB layout verification but maintain compatible footprint dimensions (7.00mm x 5.00mm).

Parameter Comparison

Engineering Selection Recommendations

The 590DB100M000DG from Skyworks Solutions Inc. is a direct functional substitute for the discontinued AX7MAF1-100.0000C. Both components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental handling and regulatory compliance.

Key considerations for selection:

• Electrical Compatibility: All critical electrical parameters (frequency, output type, supply voltage, function, stability, and temperature range) are identical.
• Package Footprint: Both components occupy the same 7.00mm x 5.00mm footprint. The 6-SMD package of the Skyworks part versus the 8-SMD of the Abracon part requires verification of PCB pad layout compatibility.
• Current Draw: The Skyworks substitute draws a maximum of 110mA compared to 68mA for the original part. Power supply design must accommodate this higher current requirement.
• Product Availability: The Skyworks part is currently active in production, ensuring long-term procurement availability.

Frequently Asked Questions (FAQ)

Q: Can the 590DB100M000DG directly replace the AX7MAF1-100.0000C without PCB modifications?

A: Electrical compatibility is confirmed across all functional parameters. However, the difference in SMD pad count (6-SMD vs. 8-SMD) requires verification of PCB pad layout. If the original design uses all 8 pads, pad configuration must be reviewed. Consult component datasheets for exact pinout and pad assignments.

Q: What is the impact of the higher current draw (110mA vs. 68mA) on system design?

A: The Skyworks substitute requires 42mA additional current during normal operation. Power supply capacity and current delivery paths must be evaluated to ensure adequate headroom. Thermal management and voltage regulation stability should be verified under worst-case conditions.

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

A: Both components are ROHS3 compliant and carry identical MSL 1 (Unlimited) ratings. No compliance gaps exist for standard industrial and commercial applications.

Q: What should be verified before implementing this substitution?

A: Confirm PCB pad layout compatibility with the 6-SMD package configuration, verify power supply capacity for the increased current requirement, and validate signal integrity with the substitute oscillator in the target application circuit.
