TPS22993PRLWT Equivalent & Substitute Parts

Part Overview

The TPS22993PRLWT is a Power Management IC (PMIC) functioning as a power switch with N-channel output configuration. This device operates as a 1:1 ratio switch with four outputs, designed for high-side switching applications in low-voltage systems. The part is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS22993PRLWT is determined by the following critical parameters:

• Electrical Compatibility: Output type (N-Channel), output configuration (High Side), number of outputs (4), interface (I2C), load voltage range (1V ~ 3.6V), and operating temperature range (-40°C ~ 85°C)
• Mechanical Compatibility: Package type (20-WFQFN 3x3), surface mount mounting type
• Performance Specifications: Current output capability and on-resistance characteristics

The identified substitutes maintain these core parameters while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

TPS22993RLWR is the direct functional equivalent. This part maintains identical electrical specifications (1.2A output current, 15mOhm on-resistance, Load Discharge feature) and mechanical compatibility (20-WFQFN package). The primary advantages are active product status and ROHS3 compliance. Moisture sensitivity level remains at MSL 1 (Unlimited), matching the original part.

TPS22994RUKR is the manufacturer-recommended alternative. This part shares the same core architecture (4-output N-channel high-side switch, I2C interface, 1V ~ 3.6V load voltage) and package footprint. The output current specification is reduced to 1A (versus 1.2A), and the Load Discharge feature is not listed. Both parts carry ROHS3 compliance and are actively produced. The TPS22994RUKR features an exposed pad variant of the 20-WFQFN package and carries MSL 2 rating (1 Year).

Selection between these substitutes depends on current output requirements and moisture handling protocols in manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can TPS22993RLWR be used as a direct replacement for TPS22993PRLWT?

A: Yes. The TPS22993RLWR maintains identical electrical and mechanical specifications. Both parts feature 1.2A maximum output current, 15mOhm on-resistance, four outputs, I2C interface, and 20-WFQFN (3x3) package. The primary difference is product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the difference between TPS22993RLWR and TPS22994RUKR?

A: Both are active alternatives with identical package footprints and core functionality. The TPS22994RUKR has a reduced maximum output current specification (1A versus 1.2A) and does not list the Load Discharge feature. The TPS22994RUKR offers higher inventory availability and features an exposed pad package variant.

Q: Are the package footprints identical between all three parts?

A: The TPS22993PRLWT and TPS22993RLWR use standard 20-WFQFN (3x3) packages. The TPS22994RUKR uses a 20-WFQFN Exposed Pad variant. Both footprints are mechanically compatible for surface mount assembly, though the exposed pad design may provide improved thermal performance.

Q: What is the impact of the reduced current rating on TPS22994RUKR?

A: The TPS22994RUKR is rated for 1A maximum output current compared to 1.2A for the original part. This specification difference must be evaluated against actual circuit load requirements. Applications requiring sustained output currents above 1A should use TPS22993RLWR.

Q: How do the RoHS compliance statuses affect part selection?

A: The TPS22993PRLWT is RoHS non-compliant. Both substitute parts (TPS22993RLWR and TPS22994RUKR) are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, either substitute part is acceptable.

Q: What are the moisture sensitivity considerations?

A: The TPS22993PRLWT and TPS22993RLWR carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions. The TPS22994RUKR carries MSL 2 (1 Year) rating, requiring storage in controlled humidity environments and limiting shelf life to one year from manufacturing date.
