UCC2895Q Equivalent & Substitute Parts

Part Overview

The UCC2895Q is a Phase-Shifted Full-Bridge Regulator Positive Output DC-DC Controller IC manufactured by Texas Instruments in a 20-PLCC (9x9) package. This component functions as an offline switching full-bridge controller with PWM output configuration, designed for power management applications requiring phase-shifted full-bridge topology.

The UCC2895Q is classified as obsolete. Identifying suitable substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this controller is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UCC2895Q is determined by strict equivalence across the following critical parameters:

• Base product number (UCC2895 series)
• Topology (Phase-Shifted Full-Bridge)
• Output type and configuration (PWM, Positive output)
• Supply voltage range (10V ~ 16.5V)
• Switching frequency (1MHz)
• Control features (Frequency Control, Soft Start, Sync)
• Operating temperature range (-40°C ~ 85°C)
• Compliance certifications (ROHS3, REACH Unaffected)

The UCC2895DWTR qualifies as a direct substitute based on identical functional specifications and electrical parameters. The primary difference is packaging format: the original uses 20-PLCC (J-Lead), while the substitute uses 20-SOIC. Both are surface-mount packages with equivalent pin counts and electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The UCC2895DWTR is the qualified substitute for the obsolete UCC2895Q. Both components share identical electrical specifications, control features, and compliance certifications (ROHS3 Compliant, REACH Unaffected).

The UCC2895DWTR offers the additional advantage of active product status, ensuring continued manufacturer support, documentation availability, and long-term supply chain reliability. The packaging transition from 20-PLCC to 20-SOIC requires PCB layout modification but does not affect electrical performance or functional compatibility.

Selection of the UCC2895DWTR is appropriate for new designs, production continuity, and component replacement applications where the UCC2895Q is specified.

Frequently Asked Questions (FAQ)

Q: Can the UCC2895DWTR directly replace the UCC2895Q without circuit modifications?

A: The UCC2895DWTR is electrically equivalent to the UCC2895Q. However, the package change from 20-PLCC to 20-SOIC requires PCB footprint redesign. Pin assignments remain identical, but physical dimensions and land patterns differ. Circuit schematic modifications are not required.

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

A: The UCC2895Q uses a 20-PLCC (J-Lead) package, while the UCC2895DWTR uses a 20-SOIC package. All electrical parameters, control features, and performance specifications are identical.

Q: Why is the UCC2895Q classified as obsolete?

A: The UCC2895Q has reached end-of-life status. The UCC2895DWTR represents the active continuation of this product line with identical functionality in an alternative package format.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and carry identical MSL ratings (2, 1 Year). Compliance certifications are equivalent.

Q: What packaging options are available for the UCC2895 base product?

A: The UCC2895 base product is available in multiple package formats. The UCC2895DWTR in 20-SOIC is the active substitute for the obsolete UCC2895Q in 20-PLCC.

Q: Is the UCC2895DWTR suitable for new product designs?

A: Yes. The UCC2895DWTR is classified as active product status and is appropriate for new designs requiring phase-shifted full-bridge DC-DC controller functionality.
