Parameter Comparison

Engineering Selection Recommendations

The 561AAA001077ACGR is the direct substitute for the 561AAA001077ABG based on the following engineering criteria:

Product Status Alignment: The substitute part carries an "Active" product status, ensuring ongoing manufacturing availability, technical support, and supply chain continuity. The original part's "Not For New Designs" status makes the active substitute the appropriate choice for sustained production.

Electrical Equivalence: Both parts operate identically across all specified electrical parameters, including LVPECL output, 500MHz to 3GHz frequency range, ±20ppm stability, and 160mA maximum supply current. The substitute's voltage specification (2.5V to 3.3V) encompasses the original part's discrete voltage options (2.5V, 3.3V).

Mechanical Compatibility: Identical package type, physical dimensions, and form factor ensure direct PCB layout compatibility without redesign requirements.

Compliance Certification: Both parts maintain ROHS3 compliance and MSL 1 rating, satisfying regulatory and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can the 561AAA001077ACGR be used as a direct replacement for the 561AAA001077ABG in existing designs?

A: Yes. The substitute part meets all electrical, mechanical, and compliance specifications of the original part. No circuit modifications or PCB layout changes are required for substitution.

Q: What is the difference between the supply voltage specifications "2.5V, 3.3V" and "2.5V to 3.3V"?

A: Both specifications indicate the oscillator operates at 2.5V and 3.3V supply voltages. The substitute's range notation (2.5V to 3.3V) encompasses the original part's discrete voltage options. Functional performance is equivalent across the specified voltage range.

Q: Are there any differences in current consumption between these parts?

A: The maximum supply current is 160mA for both parts. The substitute part specifies an additional parameter: maximum supply current in disable mode is 73mA. This additional specification does not affect substitution compatibility.

Q: Is the 6-SMD, No Lead package identical between both parts?

A: Yes. Both parts use the same 6-SMD, No Lead package with identical physical dimensions of 7.00mm x 5.00mm x 1.43mm, ensuring mechanical and electrical compatibility on the PCB.

Q: What is the significance of the "Active" product status for the substitute part?

A: Active product status indicates the substitute part is in current production, supported by the manufacturer, and available for new orders. This ensures long-term supply chain reliability and technical support availability.
