TPS72216DBVR Equivalent & Substitute Parts

Part Overview

The TPS72216DBVR is a linear voltage regulator IC manufactured by Texas Instruments, designed for positive fixed 1.6V output at 50mA in SOT-23-5 surface mount packaging. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The device provides Enable control features with protection against overcurrent, overtemperature, and reverse polarity conditions, operating across the industrial temperature range of -40°C to 125°C.

Substitute Part Grouping Explanation

Substitution for the TPS72216DBVR is determined by the following critical parameters: output voltage (1.6V fixed), package type (SOT-23-5), surface mount mounting, positive output configuration, and Enable control feature. Substitute parts are grouped into two categories based on output current capability:

Category 1: Direct Parametric Equivalent

TPS72216DBVT (Texas Instruments) — identical electrical specifications with Tape & Reel packaging instead of bulk

Category 2: Higher Current Capacity Substitutes

S-1315 series (ABLIC Inc.) — 200mA output current, maintains 1.6V fixed output, SOT-23-5 package, Enable control
S-1333 series (ABLIC Inc.) — 300mA output current, maintains 1.6V fixed output, SOT-23-5 package, Enable control, enhanced PSRR

All substitute parts maintain the same output voltage, package form factor, and control interface. Higher current capacity parts provide design margin for applications requiring increased load current while preserving pin compatibility and thermal characteristics.

Engineering Selection Recommendations

For Direct Replacement (Obsolete to Active): TPS72216DBVT is the primary recommendation as the active equivalent from Texas Instruments. It maintains identical electrical specifications and operating temperature range (-40°C to 125°C), ensuring seamless substitution in existing designs. Both parts are ROHS3 compliant with MSL 1 rating.

For Designs with Current Margin Requirements: The S-1315 series (200mA) and S-1333 series (300mA) from ABLIC Inc. provide higher output current capacity while maintaining the 1.6V fixed output and SOT-23-5 package. These parts are active products with ROHS3 compliance. Note that operating temperature is reduced to -40°C to 85°C, which may impact applications requiring the full industrial temperature range of the original TPS72216DBVR.

Compliance Considerations: All substitute parts maintain ROHS3 compliance, MSL 1 rating, and EAR99 export classification. REACH status is unaffected for all listed alternatives.

Frequently Asked Questions (FAQ)

Q: Can TPS72216DBVT directly replace TPS72216DBVR? A: Yes. TPS72216DBVT is the parametric equivalent with identical electrical specifications. The only difference is packaging format (Tape & Reel versus bulk). Both maintain the same output voltage, current rating, dropout voltage, and operating temperature range.

Q: What is the key difference between S-1315 and S-1333 series substitutes? A: Output current capacity and PSRR performance. S-1315 series provides 200mA output current with 60dB PSRR at 1kHz. S-1333 series provides 300mA output current with 75dB PSRR at 1kHz. Both maintain 1.6V fixed output and SOT-23-5 packaging.

Q: Are ABLIC substitutes pin-compatible with the TPS72216DBVR? A: Yes. All substitute parts use SOT-23-5 (SC-74A) packaging with identical pinout. Surface mount placement and PCB layout remain unchanged.

Q: What is the impact of reduced operating temperature on ABLIC substitutes? A: ABLIC parts operate from -40°C to 85°C versus the original TPS72216DBVR range of -40°C to 125°C. Applications requiring operation above 85°C must use TPS72216DBVT or verify thermal performance in the specific application environment.

Q: Do all substitutes include Enable control functionality? A: Yes. All listed substitutes maintain the Enable control feature present in the original TPS72216DBVR.

Q: What protection features are provided by each substitute? A: TPS72216DBVT provides overcurrent, overtemperature, and reverse polarity protection identical to the original. S-1315 series provides overcurrent protection. S-1333 series provides overcurrent and thermal shutdown protection.
