UCC2803PW Equivalent & Substitute Parts

Part Overview

The UCC2803PW is an active PWM controller integrated circuit manufactured by Texas Instruments, designed for power supply applications requiring multiple output regulation. This Surface Mount device operates within a supply voltage range of 3.6V to 11V and is qualified to automotive standards (AEC-Q100). The part maintains active product status with 700 units currently in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this power management category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UCC2803PW is determined by the following critical parameters:

• Package compatibility: 8-TSSOP form factor with identical 0.173" (4.40mm) width
• Supply voltage overlap: Minimum 3.6V and maximum voltage ≥ 11V
• Surface Mount mounting type
• Active product status
• RoHS3 compliance
• Identical MSL rating (2, 1 Year)

The UCC2813PW-3 qualifies as a parametric equivalent based on these criteria. Both devices share the same package footprint, supply voltage minimum threshold, mounting technology, and compliance certifications. Functional differences in topology and output configuration do not preclude substitution when electrical interface requirements are met.

Parameter Comparison

Engineering Selection Recommendations

Selection between UCC2803PW and UCC2813PW-3 shall be based on the following criteria:

UCC2803PW is the primary selection when operating temperature requirements extend to 125°C (TA). This device maintains automotive-grade qualification (AEC-Q100) across the full specified temperature range.

UCC2813PW-3 is suitable for applications where maximum operating temperature does not exceed 85°C (TA). This substitute provides equivalent package compatibility, supply voltage performance, and compliance certifications. The higher maximum supply voltage rating (12V vs. 11V) presents no constraint for applications designed within the UCC2803PW specification envelope.

Both devices maintain identical RoHS3 compliance and MSL ratings, ensuring equivalent handling and storage requirements. Selection shall prioritize thermal operating range requirements as the primary differentiator.

Frequently Asked Questions (FAQ)

Q: Can UCC2813PW-3 be used as a direct replacement for UCC2803PW in all applications?

A: UCC2813PW-3 is compatible when the application operating temperature does not exceed 85°C (TA). If your design operates within this thermal envelope, the substitute provides equivalent electrical interface and mechanical compatibility. If sustained operation above 85°C is required, UCC2803PW is the appropriate selection.

Q: Are the package footprints identical between these two parts?

A: Yes. Both UCC2803PW and UCC2813PW-3 use the 8-TSSOP package with 0.173" (4.40mm) width. PCB layout and reflow profiles remain unchanged during substitution.

Q: What is the significance of the supply voltage difference (11V vs. 12V maximum)?

A: UCC2813PW-3 supports a higher maximum supply voltage (12V) compared to UCC2803PW (11V). This extended rating does not affect substitution for designs operating within the UCC2803PW specification. The substitute remains fully functional and compliant at all voltages up to 11V.

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

A: Yes. Both devices carry MSL rating 2 (1 Year), requiring identical storage, handling, and reflow procedures. No additional precautions are necessary when substituting between these parts.

Q: What compliance certifications apply to both parts?

A: Both UCC2803PW and UCC2813PW-3 are ROHS3 compliant and REACH unaffected. Automotive qualification (AEC-Q100) applies to UCC2803PW. Verify application-specific compliance requirements before final selection.
