UCC2912PWPR Equivalent & Substitute Parts

Part Overview

The UCC2912PWPR is a hot swap controller IC manufactured by Texas Instruments, designed for general-purpose power management applications. This single-channel device integrates an internal switch and provides programmable current limiting and fault timeout capabilities. The UCC2912PWPR is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design support and procurement continuity. The substitute part maintains identical electrical and mechanical specifications while offering active product status and improved availability.

Substitute Part Grouping Explanation

The UCC2912PWP qualifies as a direct substitute for the UCC2912PWPR based on the following substitution criteria:

Electrical Equivalence: Both parts share identical voltage supply range (3V ~ 8V), maximum output current (4A), supply current (1 mA), and operating temperature range (-40°C ~ 85°C).

Functional Equivalence: Both devices are single-channel hot swap controllers with internal switches, latched fault protection, thermal limiting, and programmable current limit and fault timeout features.

Mechanical Compatibility: Both parts use the 24-PowerTSSOP package (0.173", 4.40mm Width) with identical pinout and footprint requirements.

Regulatory Compliance: Both parts maintain ROHS3 compliance, identical moisture sensitivity level (MSL 2, 1 Year), and REACH unaffected status.

Base Product Number: Both parts share the same base product number (UCC2912), confirming they are variants of the same design platform.

The primary distinction is product status: UCC2912PWPR is obsolete, while UCC2912PWP maintains active status with superior availability.

Parameter Comparison

Engineering Selection Recommendations

The UCC2912PWP is the appropriate selection for new designs and procurement activities. As an active product with identical electrical, functional, and mechanical specifications, it provides equivalent performance while ensuring long-term supply chain continuity and manufacturer support.

The UCC2912PWPR, classified as obsolete, should be reserved for legacy system maintenance only where existing inventory is available. For all new applications, the UCC2912PWP offers superior lifecycle support and compliance assurance.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The 24-PowerTSSOP package is suitable for surface-mount assembly processes without modification to existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can UCC2912PWP be used as a direct replacement for UCC2912PWPR in existing designs?

A: Yes. The UCC2912PWP is electrically and mechanically identical to the UCC2912PWPR. No circuit modifications, PCB layout changes, or firmware updates are required. The 24-PowerTSSOP package footprint is identical, and all electrical parameters match exactly.

Q: What is the primary reason for substitution?

A: The UCC2912PWPR is classified as obsolete. The UCC2912PWP is the active equivalent part, ensuring continued availability and manufacturer support for procurement and technical documentation.

Q: Are there any packaging differences between these parts?

A: The UCC2912PWPR is supplied in standard packaging, while the UCC2912PWP is supplied in tube packaging. Both use the identical 24-PowerTSSOP case. Tube packaging does not affect electrical performance or PCB assembly compatibility.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the UCC2912PWPR and UCC2912PWP are ROHS3 compliant, REACH unaffected, and maintain identical moisture sensitivity levels (MSL 2, 1 Year).

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on matching voltage supply range (3V ~ 8V), output current rating (4A), operating temperature range (-40°C ~ 85°C), package type (24-PowerTSSOP), channel count (1), and functional features (latched fault, thermal limit, programmable current limit and fault timeout).

Q: Is the UCC2912PWP suitable for high-reliability applications?

A: Both parts share identical electrical specifications and compliance certifications. Selection should be based on application requirements and supply chain considerations. The active status of UCC2912PWP provides superior long-term support for high-reliability programs.
