Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 569BAAC002035ABG is determined by strict alignment across the following critical parameters:

Frequency and Output Characteristics: The substitute part must operate at 299.808 MHz with LVDS output to maintain signal integrity and timing specifications in the target application.

Supply Voltage Compatibility: The substitute must support the same voltage supply range or a compatible subset. The original part accepts 1.8V, 2.5V, and 3.3V discrete levels.

Frequency Stability: A ±20ppm frequency stability specification is required to ensure timing accuracy within application tolerances.

Package and Mounting: The 8-SMD, No Lead surface mount package with identical physical dimensions (7.00mm x 5.00mm, 1.33mm max height) is mandatory for PCB layout compatibility.

Operating Temperature Range: The -40°C ~ 85°C operating range must be maintained or exceeded.

Function and Control: Enable/Disable functionality must be preserved.

The 569BAAC002035ACG meets all substitution criteria and is classified as the manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The 569BAAC002035ACG is the qualified substitute for the 569BAAC002035ABG based on the following engineering criteria:

Product Status Alignment: The substitute carries an Active product status, ensuring ongoing manufacturer support, availability, and compliance with current industry standards. The original part's "Not For New Designs" designation indicates end-of-life status.

Compliance and Certification: Both parts maintain ROHS3 compliance and identical Moisture Sensitivity Level (MSL) ratings, confirming equivalent environmental and regulatory standing.

Electrical Performance: The substitute delivers identical frequency (299.808 MHz), frequency stability (±20ppm), output type (LVDS), operating temperature range (-40°C ~ 85°C), and functional capability (Enable/Disable). The supply voltage specification in the substitute (1.8V ~ 3.3V) covers the discrete voltage levels supported by the original part.

Physical and Mechanical Compatibility: Identical package type, dimensions, and mounting characteristics ensure direct PCB layout compatibility without redesign.

Current Consumption: The substitute exhibits lower maximum supply current (140mA versus 167mA), representing an improvement in power efficiency while maintaining all functional specifications.

Frequently Asked Questions (FAQ)

Q: Can the 569BAAC002035ACG be used as a direct replacement for the 569BAAC002035ABG?

A: Yes. Both parts share identical frequency, output type (LVDS), operating temperature range, package configuration, and physical dimensions. The substitute is electrically and mechanically compatible for direct substitution.

Q: What is the difference in supply voltage specification between the two parts?

A: The original part specifies discrete voltage levels (1.8V, 2.5V, 3.3V), while the substitute specifies a continuous range (1.8V ~ 3.3V). This range encompasses all discrete levels supported by the original part, ensuring full compatibility.

Q: Does the lower maximum supply current in the substitute affect performance?

A: No. The 140mA maximum current specification in the substitute (versus 167mA in the original) represents improved power efficiency. Both parts meet the frequency stability and output specifications required for LVDS oscillator applications.

Q: Are there any PCB layout modifications required when switching to the substitute?

A: No. Both parts use identical 8-SMD, No Lead packages with matching physical dimensions (7.00mm x 5.00mm) and seated height (1.33mm max). No PCB redesign is necessary.

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

A: Active status indicates the substitute is in current production with ongoing manufacturer support, quality assurance, and long-term availability. This contrasts with the original part's "Not For New Designs" status, which signals end-of-life and potential supply constraints.

Q: Are both parts RoHS compliant?

A: Yes. Both the 569BAAC002035ABG and 569BAAC002035ACG are ROHS3 compliant with identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), confirming equivalent environmental and regulatory compliance.
