Key Parameters

Substitute Part Grouping Explanation

Substitute components for the TPS22993PRLWR are identified based on strict electrical and mechanical compatibility criteria. The following parameters define acceptable substitution:

• Functional equivalence: General Purpose Switch type with N-Channel output configuration
• Interface compatibility: I2C control interface
• Electrical specifications: Load voltage range 1V ~ 3.6V, 4 outputs in high-side configuration
• Thermal range: Operating temperature -40°C ~ 85°C
• Package compatibility: 20-WFQFN surface mount package
• Regulatory compliance: ROHS3 Compliant

Two substitute parts meet these criteria with the following distinctions:

TPS22993RLWR — Direct equivalent with identical electrical specifications and active product status.

TPS22994RUKR — Manufacturer-recommended alternative with reduced maximum output current (1A vs 1.2A) and different packaging format.

Parameter Comparison

Engineering Selection Recommendations

TPS22993RLWR is the primary substitute for the obsolete TPS22993PRLWR. This part maintains identical electrical specifications, including maximum output current of 1.2A and on-resistance of 15mOhm. The component holds Active product status, ensuring long-term availability and supply chain stability. Both Load Discharge and Slew Rate Controlled features are retained. Moisture sensitivity level remains at MSL 1 (Unlimited). This substitute provides direct functional replacement with no design modifications required.

TPS22994RUKR serves as an alternative when supply constraints affect TPS22993RLWR availability. This part is manufacturer-recommended and maintains all core functional parameters including I2C interface, 4-output high-side N-channel configuration, and identical thermal operating range. The maximum output current specification is reduced to 1A, representing a 16.7% decrease from the original 1.2A rating. The Rds On value is not specified for this part. Load Discharge feature is not listed. Moisture sensitivity level increases to MSL 2 (1 Year), requiring controlled storage conditions. Selection of TPS22994RUKR requires verification that application load current does not exceed 1A.

Both substitute parts maintain ROHS3 compliance and identical operating temperature range (-40°C ~ 85°C). Both are manufactured by Texas Instruments and packaged in 20-WFQFN surface mount configuration.

Frequently Asked Questions (FAQ)

Q: Can TPS22993RLWR be used as a direct replacement for TPS22993PRLWR?

A: Yes. TPS22993RLWR is electrically and mechanically identical to TPS22993PRLWR. All electrical parameters, including maximum output current (1.2A), on-resistance (15mOhm), and feature set (Load Discharge, Slew Rate Controlled) are equivalent. The primary difference is product status: TPS22993RLWR is Active, while TPS22993PRLWR is Obsolete. No design modifications are required.

Q: What are the limitations of TPS22994RUKR as a substitute?

A: TPS22994RUKR has two material differences from TPS22993PRLWR. First, maximum output current is reduced to 1A, compared to 1.2A in the original part. Second, the Load Discharge feature is not specified for this part. Applications requiring output current above 1A or dependent on load discharge functionality must use TPS22993RLWR instead.

Q: Are there packaging differences between the substitute parts?

A: Yes. TPS22993PRLWR is supplied in Tube packaging. TPS22993RLWR is supplied in Tape & Reel (TR) format. TPS22994RUKR is supplied in Cut Tape (CT) and Digi-Reel® format. All three parts use the same 20-WFQFN surface mount package footprint. Packaging format affects handling, storage, and assembly processes but does not impact electrical performance.

Q: What is the difference in moisture sensitivity between these parts?

A: TPS22993PRLWR and TPS22993RLWR both have MSL 1 (Unlimited) rating, allowing unlimited shelf life under normal storage conditions. TPS22994RUKR has MSL 2 (1 Year) rating, requiring that the component be used within one year of the manufacturing date if stored at standard conditions (23°C, 50% relative humidity). MSL 2 components require controlled storage or baking before reflow if shelf life is exceeded.

Q: Are all three parts ROHS3 compliant?

A: Yes. TPS22993PRLWR, TPS22993RLWR, and TPS22994RUKR are all ROHS3 Compliant. All three parts meet the same regulatory requirements for hazardous substance restrictions.

Q: Which substitute should be selected for new designs?

A: For new designs, TPS22993RLWR is the recommended choice. It provides complete functional equivalence to the obsolete TPS22993PRLWR with Active product status, ensuring long-term availability. TPS22994RUKR should be considered only when TPS22993RLWR is unavailable and application requirements allow for reduced maximum output current (1A maximum) and absence of Load Discharge functionality.
