TPS76327DBVR Equivalent & Substitute Parts

Part Overview

The TPS76327DBVR is a linear voltage regulator IC manufactured by Texas Instruments, delivering a fixed positive output of 2.7V at 150mA in a SOT-23-5 surface mount package. This device is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. The part provides integrated protection features including over-current, over-temperature, and reverse polarity protection, with an enable control feature for power management applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS76327DBVR are classified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Fixed positive output voltage of 2.7V
• Output current capability of 150mA minimum
• Maximum input voltage of 10V or greater
• Surface mount package in SOT-23-5 or compatible footprint (SC-74A, SOT-753)
• Enable control feature
• Operating temperature range of -40°C to 125°C or compatible subset
• ROHS3 compliance

Substitute parts are grouped into two categories: parametric equivalents (identical electrical specifications and packaging) and manufacturer-recommended alternatives (functionally equivalent with minor specification variations).

Parameter Comparison

Engineering Selection Recommendations

For applications requiring direct replacement of the obsolete TPS76327DBVR in cut tape packaging, the TPS76327DBVT provides identical electrical specifications with tape and reel packaging. For new designs or production requiring active product status, the TPS76427DBVR and TPS76427DBVT from Texas Instruments maintain full electrical and thermal compatibility while offering current product lifecycle support.

ABLIC Inc. parts S-1200B27-M5T1U and S-L2980A27MC-TF-U are active alternatives with superior quiescent current performance (1 µA versus 100 µA). These parts are suitable for low-power applications but operate within a reduced temperature range (-40°C to 85°C). Both are ROHS3 compliant.

Microchip Technology TC1185-2.7VCT713 is an active alternative with full temperature range support (-40°C to 125°C) and ROHS3 compliance. This part operates with a maximum input voltage of 6V, restricting its use to applications with lower input voltage requirements compared to the original 10V specification.

Torex Semiconductor Ltd parts XC6204B272MR-G and XC6209B272MR-G are active alternatives with SOT-25 packaging variants. These parts maintain 10V input voltage capability and ROHS3 compliance but operate within a reduced temperature range (-40°C to 85°C). Package footprint differences require PCB layout verification before substitution.

All substitute parts listed carry ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original part.

Frequently Asked Questions (FAQ)

Q: Can TPS76327DBVT be used as a direct replacement for TPS76327DBVR?

A: Yes. Both parts are electrically identical with matching output voltage (2.7V), output current (150mA), input voltage rating (10V), quiescent current (100 µA), PSRR (60dB at 1kHz), and operating temperature range (-40°C to 125°C). The difference is packaging format: DBVR is cut tape while DBVT is tape and reel. PCB footprint and soldering processes remain unchanged.

Q: What are the advantages of TPS76427DBVR over the obsolete TPS76327DBVR?

A: The TPS76427DBVR provides identical electrical specifications and maintains active product status with ongoing manufacturer support. All other parameters including output voltage, current rating, input voltage, quiescent current, PSRR, temperature range, and package remain equivalent.

Q: Are ABLIC parts suitable for high-temperature applications?

A: No. ABLIC S-1200B27-M5T1U and S-L2980A27MC-TF-U operate within -40°C to 85°C, which is narrower than the original TPS76327DBVR specification of -40°C to 125°C. These parts are suitable only for applications not exceeding 85°C ambient or junction temperature.

Q: What is the impact of using TC1185-2.7VCT713 with input voltages above 6V?

A: The TC1185-2.7VCT713 has a maximum input voltage rating of 6V, compared to 10V for the TPS76327DBVR. Using this part with input voltages between 6V and 10V violates the device specification and may result in device damage or failure. This part is suitable only for applications with input voltages not exceeding 6V.

Q: Can Torex XC6204B272MR-G or XC6209B272MR-G be used without PCB modification?

A: Both Torex parts use SOT-25 packaging instead of SOT-23-5. While the pin count and functional pinout are compatible, the physical footprint differs. PCB layout verification is required to confirm pad spacing and component placement compatibility before substitution.

Q: Do all substitute parts meet the same compliance standards as TPS76327DBVR?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original TPS76327DBVR. All parts carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.
