Key Parameters

Substitute Part Grouping Explanation

Substitution of the 561BAA001076ABG is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Output type: LVDS
• Frequency outputs: 1.65GHz and 2.247GHz
• Frequency stability: ±20ppm
• Function: Enable/Disable capability
• Operating temperature range: -40°C ~ 85°C

Mechanical Compatibility Requirements:

• Package type: 6-SMD, No Lead
• Physical dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm)
• Height: 0.056" (1.43mm)

Supply Voltage Consideration: The original part operates at a fixed 2.5V supply. Substitute parts must either match this specification or provide a wider supply voltage range that includes 2.5V as an operational point, ensuring compatibility with existing power delivery infrastructure.

Compliance Requirements:

• RoHS3 compliance
• MSL rating of 1 (Unlimited)

The Skyworks Solutions 561BAA001076ACG meets all electrical, mechanical, and compliance criteria for substitution.

Parameter Comparison

Engineering Selection Recommendations

The 561BAA001076ACG is the manufacturer-recommended substitute for the 561BAA001076ABG. Key selection factors:

Product Status Advantage: The substitute part carries Active product status, ensuring continued availability and manufacturer support, whereas the original part is designated "Not For New Designs."

Supply Voltage Range: The substitute operates across 1.8V to 3.3V, providing broader supply voltage compatibility while maintaining full operation at the original 2.5V specification point. This expanded range offers design flexibility for future applications.

Power Consumption Improvement: The substitute part demonstrates reduced maximum supply current (130mA versus 157mA), resulting in lower power dissipation and improved thermal performance in the same package footprint.

Compliance and Certification: Both parts maintain identical RoHS3 compliance and MSL rating of 1 (Unlimited), ensuring equivalent environmental and reliability standards.

Electrical and Mechanical Equivalence: Identical LVDS output type, frequency outputs (1.65GHz and 2.247GHz), frequency stability (±20ppm), operating temperature range (-40°C to 85°C), and physical package dimensions (6-SMD, No Lead; 7.00mm x 5.00mm x 1.43mm) ensure direct functional substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the 561BAA001076ACG directly replace the 561BAA001076ABG in existing designs?

A: Yes. Both parts share identical LVDS output characteristics, frequency outputs, frequency stability, operating temperature range, and physical package dimensions. The substitute operates at the same 2.5V point within its 1.8V to 3.3V supply range, ensuring functional equivalence without circuit modification.

Q: What is the primary advantage of switching to the 561BAA001076ACG?

A: The substitute part is Active in product status, ensuring long-term availability and manufacturer support. It also provides improved power efficiency with 27mA lower maximum supply current and offers broader supply voltage flexibility (1.8V to 3.3V) compared to the fixed 2.5V of the original part.

Q: Are the physical packages identical?

A: Yes. Both parts use 6-SMD, No Lead packaging with identical dimensions of 0.276" L x 0.197" W (7.00mm x 5.00mm) and height of 0.056" (1.43mm). PCB layout and assembly processes require no modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant with MSL rating of 1 (Unlimited), meeting identical environmental and reliability requirements.

Q: What is the frequency stability specification for both parts?

A: Both the original and substitute parts maintain ±20ppm frequency stability across their operating temperature range of -40°C to 85°C.

Q: Are there any electrical parameter differences that affect circuit design?

A: The primary difference is supply voltage specification. The original part requires exactly 2.5V, while the substitute accepts 1.8V to 3.3V. The substitute's lower maximum supply current (130mA versus 157mA) may reduce power supply sizing requirements but does not affect circuit functionality.
