UCC2801PW Equivalent & Substitute Parts

Part Overview

The UCC2801PW is an active PWM controller IC manufactured by Texas Instruments, designed for power supply applications requiring multi-output regulation. This Surface Mount device operates within a supply voltage range of 7.4V to 11V and is housed in an 8-TSSOP package. The part is currently in active production status with ROHS3 compliance and is suitable for applications requiring PWM control functionality.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter ranges, allowing for design flexibility and supply chain alternatives.

Key Parameters

Substitute Part Grouping Explanation

The UCC2813PW-1 qualifies as a parametric equivalent based on the following criteria:

Matching Parameters:

• Identical package type: 8-TSSOP (0.173", 4.40mm Width)
• Identical mounting type: Surface Mount
• Overlapping supply voltage range: 7.4V ~ 12V (encompasses the main part's 7.4V ~ 11V range)
• Identical manufacturer: Texas Instruments
• Identical RoHS compliance: ROHS3 Compliant
• Identical MSL rating: 2 (1 Year)

Functional Compatibility: Both devices operate as PWM controllers within the Power Management (PMIC) category and share the same physical footprint, enabling direct substitution in applications where the electrical characteristics align with design requirements.

Engineering Selection Recommendations

UCC2813PW-1 Substitution Criteria:

The UCC2813PW-1 is suitable as a substitute for the UCC2801PW in applications where the operating temperature requirement does not exceed 85°C. Both parts maintain identical physical packaging, mounting characteristics, and regulatory compliance status (ROHS3, REACH Unaffected, EAR99 classification).

The supply voltage range of the UCC2813PW-1 (7.4V ~ 12V) encompasses the operational range of the UCC2801PW (7.4V ~ 11V), ensuring compatibility within the main part's specified voltage window.

Selection should be based on application-specific temperature requirements and functional topology compatibility as defined in the device datasheets.

Frequently Asked Questions (FAQ)

Q: Can the UCC2813PW-1 be used as a direct replacement for the UCC2801PW?

A: Direct substitution is possible when the application operating temperature remains within the UCC2813PW-1 specification of -40°C to 85°C. Both parts share identical 8-TSSOP packaging and mounting characteristics, allowing PCB-level compatibility without layout modifications.

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

A: The primary difference is the maximum operating temperature specification. The UCC2801PW operates to 125°C, while the UCC2813PW-1 operates to 85°C. Both parts maintain identical supply voltage ranges within their respective specifications and share the same physical package.

Q: Are there any compliance or regulatory differences?

A: No. Both parts carry identical RoHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification, ensuring equivalent regulatory standing for procurement and deployment.

Q: Does package compatibility guarantee functional equivalence?

A: Package and mounting compatibility confirm physical interchangeability at the PCB level. Functional equivalence requires alignment of electrical specifications and application topology requirements as defined in respective device datasheets.

Q: What supply voltage range applies when substituting these parts?

A: The safe operating range for substitution is 7.4V to 11V, which represents the intersection of both parts' supply voltage specifications. The UCC2813PW-1 supports operation to 12V, but the main part specification of 11V maximum should be observed for system-level design.
