Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UCD9240RGCT is determined by the following critical parameters:

• Package Compatibility: Both main and substitute parts must use the 64-VFQFN Exposed Pad (9x9) surface mount package to ensure PCB layout and thermal management compatibility.
• Voltage Supply Range: The substitute part must operate within the specified 3V ~ 3.6V supply voltage window.
• Manufacturer Series: Parts within the Fusion Digital Power™ series maintain consistent design architecture and interface protocols.
• Compliance Standards: RoHS3 compliance and MSL rating (3, 168 Hours) must be maintained for manufacturing and storage requirements.
• Product Status: Active production status ensures ongoing availability and support.

The UCD9246RGCT meets all substitution criteria as a manufacturer-recommended equivalent within the same product family.

Parameter Comparison

Engineering Selection Recommendations

The UCD9246RGCT is a direct substitute for the UCD9240RGCT based on the following engineering criteria:

• Electrical Compatibility: Both parts operate within identical voltage supply ranges (3V ~ 3.6V) and share the same Fusion Digital Power™ architecture, ensuring functional equivalence in power management applications.
• Mechanical Compatibility: Identical 64-VFQFN (9x9) package specifications with exposed pad enable direct PCB footprint compatibility without layout modifications.
• Thermal Performance: The UCD9246RGCT supports an extended operating temperature range (-40°C ~ 125°C) compared to the UCD9240RGCT (-40°C ~ 110°C), providing additional thermal margin for demanding environments.
• Regulatory Compliance: Both parts maintain ROHS3 compliance, identical MSL ratings, and active production status, ensuring consistent supply chain support and manufacturing standards.
• Application Scope: While the UCD9240RGCT targets special purpose applications and the UCD9246RGCT targets telecommunications applications, the underlying controller architecture remains compatible for both use cases within the specified electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can the UCD9246RGCT be used as a direct replacement for the UCD9240RGCT in existing designs?

A: Yes. Both parts share identical package specifications (64-VFQFN 9x9), voltage supply ranges (3V ~ 3.6V), and Fusion Digital Power™ series architecture. No PCB modifications or design changes are required for substitution.

Q: What is the primary difference between these two parts?

A: The UCD9246RGCT supports an extended operating temperature range (-40°C ~ 125°C) compared to the UCD9240RGCT (-40°C ~ 110°C). The UCD9240RGCT is designated for special purpose applications, while the UCD9246RGCT is designated for telecommunications applications.

Q: Are both parts currently available?

A: Yes. The UCD9240RGCT has 1346 units in stock, and the UCD9246RGCT has 1228 units in stock, both as new original inventory in Tape & Reel packaging.

Q: Do these parts have the same moisture sensitivity requirements?

A: Yes. Both parts carry an MSL rating of 3 (168 Hours), requiring identical storage and handling protocols during manufacturing and assembly.

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

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: Which part should be selected for high-temperature applications?

A: The UCD9246RGCT is suitable for applications requiring operation up to 125°C. The UCD9240RGCT is rated to 110°C and should be selected only when the application temperature range does not exceed this limit.
