TPS2220APWPR Equivalent & Substitute Parts

Part Overview

The TPS2220APWPR is a Power Management Integrated Circuit (PMIC) functioning as a power switch/driver with 1:1 configuration and 1A maximum output current. Manufactured by Texas Instruments, this component operates across multiple voltage levels (3.3V, 5V, 12V) and is housed in a 24-HTSSOP package. The device is classified as obsolete, necessitating identification of functionally equivalent alternatives for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution of the TPS2220APWPR is determined by strict equivalence across the following critical parameters:

• Switch Type: PCMCIA Switch
• Number of Outputs: 3
• Ratio - Input:Output: 1:1
• Output Configuration: High Side
• Interface: Serial
• Voltage - Load: 3.3V, 5V, 12V
• Current - Output (Max): 1A
• Rds On (Typ): 95mOhm
• Features: Status Flag
• Fault Protection: Current Limiting (Fixed), Over Temperature
• Operating Temperature: -40°C ~ 85°C (TA)
• Base Product Number: TPS2220

The TPS2220ADBR qualifies as a direct substitute based on identical electrical specifications and functional characteristics. The primary distinction lies in packaging format and product lifecycle status.

Engineering Selection Recommendations

The TPS2220ADBR is the manufacturer-recommended substitute for the obsolete TPS2220APWPR. Both components maintain identical electrical and functional specifications, ensuring direct functional compatibility.

Key selection factors:

• The TPS2220ADBR carries Active product status, ensuring long-term availability and manufacturer support, whereas the TPS2220APWPR is classified as Obsolete.
• Both components achieve ROHS3 compliance and maintain equivalent regulatory certifications (REACH Unaffected, EAR99 classification).
• The TPS2220ADBR features improved moisture sensitivity characteristics (MSL 1 with Unlimited shelf life) compared to the TPS2220APWPR (MSL 2 with 1-year shelf life).
• Package geometry differs between the two variants: the TPS2220APWPR uses 24-PowerTSSOP (0.173" width), while the TPS2220ADBR uses 24-SSOP (0.209" width). PCB layout modifications may be required to accommodate the dimensional difference.
• The TPS2220ADBR is supplied in Tape & Reel format, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the TPS2220ADBR directly replace the TPS2220APWPR without circuit modifications?

A: Electrical and functional specifications are identical. However, the package footprint differs in width (4.40mm versus 5.30mm). PCB layout review is necessary to confirm mechanical compatibility with existing designs.

Q: What is the primary reason for substitution?

A: The TPS2220APWPR is classified as Obsolete. The TPS2220ADBR is the active equivalent from Texas Instruments, ensuring continued availability and manufacturer support.

Q: Are there compliance differences between the two parts?

A: Both components are ROHS3 compliant and carry identical regulatory classifications (REACH Unaffected, EAR99). The TPS2220ADBR offers superior moisture sensitivity characteristics (MSL 1 versus MSL 2).

Q: What packaging formats are available?

A: The TPS2220APWPR was supplied in bulk packaging. The TPS2220ADBR is available in Tape & Reel format, optimized for high-volume automated assembly.

Q: Are the electrical performance characteristics identical?

A: Yes. Both components operate at 1A maximum output current, 95mOhm typical on-resistance, support 3.3V/5V/12V load voltages, and include identical fault protection mechanisms (current limiting and over-temperature protection).
