Substitute Part Grouping Explanation

The 569DABA001908BBG qualifies as a parametric equivalent to the 569DCBA001908BBG based on the following matching criteria:

Frequency matching: Both parts operate at 1.28127409 GHz with identical CML output configuration. Output type and frequency stability (±20ppm) are identical across both parts.

Supply voltage compatibility: Both support 1.8V, 2.5V, and 3.3V operation with enable/disable functionality, ensuring direct functional replacement in existing designs.

Electrical performance: Maximum supply current (167mA), operating temperature range (-40°C to 85°C), and frequency stability specifications are identical.

Package and mechanical compatibility: Both use 8-SMD, No Lead packaging with identical dimensions (5.00mm x 3.20mm x 1.33mm max height), allowing direct PCB footprint compatibility.

Compliance and certification: Both parts maintain ROHS3 compliance and MSL 1 rating, meeting identical environmental and regulatory requirements.

The substitution is based strictly on these electrical and mechanical parameters. Both parts belong to the Skyworks Solutions Ultra™ Si569 series and share the same base product architecture with different internal revision designations (569DCB vs. 569DAB).

Parameter Comparison

Engineering Selection Recommendations

Both the 569DCBA001908BBG and 569DABA001908BBG are classified as "Not For New Designs" by Skyworks Solutions Inc., indicating both parts have reached end-of-life status. For new design initiatives, consultation with Skyworks Solutions regarding current-generation VCXO alternatives is recommended.

For existing designs currently using either part number, direct substitution between 569DCBA001908BBG and 569DABA001908BBG is supported based on identical electrical specifications, package compatibility, and regulatory compliance. Both parts maintain ROHS3 compliance and MSL 1 rating, satisfying equivalent environmental and manufacturing requirements.

Component selection between these two part numbers should be based on current inventory availability and supply chain considerations, as electrical and mechanical performance are identical.

Frequently Asked Questions (FAQ)

Q: Can 569DABA001908BBG replace 569DCBA001908BBG in existing designs?

A: Yes. Both parts are parametrically equivalent with identical frequency (1.28127409 GHz), output type (CML), supply voltage support (1.8V, 2.5V, 3.3V), frequency stability (±20ppm), operating temperature range (-40°C to 85°C), and package configuration (8-SMD, No Lead). Direct substitution is supported without design modification.

Q: Are there package compatibility concerns between these part numbers?

A: No. Both parts use identical 8-SMD, No Lead packaging with matching dimensions (5.00mm x 3.20mm x 1.33mm max height). PCB footprints and mounting requirements are identical.

Q: What is the difference between the 569DCB and 569DAB base product numbers?

A: The base product numbers (569DCB vs. 569DAB) represent different internal revision designations within the Skyworks Solutions Ultra™ Si569 series. All specified electrical and mechanical parameters remain identical between these revisions.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both 569DCBA001908BBG and 569DABA001908BBG maintain ROHS3 compliance and MSL 1 (Unlimited) rating, meeting identical regulatory and environmental standards.

Q: Why are both parts marked "Not For New Designs"?

A: Both parts have reached end-of-life status within Skyworks Solutions' product portfolio. This designation indicates the manufacturer is no longer actively promoting these parts for new design implementations. Existing designs may continue to use available inventory, but new applications should evaluate current-generation alternatives.

Q: What supply current should be expected during operation?

A: Maximum supply current for both parts is 167mA under normal operating conditions across all supported supply voltages (1.8V, 2.5V, 3.3V).
