TPS3106K33MDBVREP Equivalent & Substitute Parts

Part Overview

The TPS3106K33MDBVREP is a single-channel power management supervisor integrated circuit manufactured by Texas Instruments, classified as a Power Management PMIC. This device functions as a simple reset/power-on reset supervisor with open drain or open collector output, designed for monitoring single voltage rails in embedded systems and industrial applications. The part is currently in active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are necessary when the original Tape & Reel packaging is unavailable or when alternative packaging formats better suit procurement and assembly requirements.

Substitute Part Grouping Explanation

Substitution of the TPS3106K33MDBVREP is determined by strict equivalence across the following critical parameters: single voltage monitoring channel, 2.941V threshold voltage, active low reset output, 65ms minimum reset timeout, SOT-23-6 package geometry, surface mount configuration, and operating temperature range of -40°C to 85°C. All substitute parts maintain identical electrical specifications and mechanical compatibility. Substitution is valid across different packaging formats (Tape & Reel to Cut Tape & Digi-Reel®) and between TPS3106 and TPS3103 base product numbers, as both series share identical functional parameters within this voltage threshold classification. Compliance certifications (RoHS3, REACH, MSL 1) remain consistent across all equivalent parts.

Engineering Selection Recommendations

All listed substitute parts maintain active product status with Texas Instruments and carry identical RoHS3 compliance and REACH unaffected certifications. Selection between TPS3106K33DBVT, TPS3106K33DBVR, TPS3103K33DBVT, and TPS3103K33DBVR should be based on packaging format requirements and inventory availability. The TPS3106K33DBVT variant offers the highest inventory level (169,210 units) in Cut Tape & Digi-Reel® format, suitable for high-volume production environments. The TPS3103 series variants provide equivalent electrical performance with alternative base product numbering. Packaging format selection (Tape & Reel versus Cut Tape & Digi-Reel®) depends on assembly line automation capabilities and component handling procedures.

Frequently Asked Questions (FAQ)

Q: Can TPS3103K33DBVR replace TPS3106K33MDBVREP in production? A: Yes. Both parts share identical voltage threshold (2.941V), reset timeout (65ms minimum), output configuration (open drain or open collector), and operating temperature range (-40°C to 85°C). The difference in base product number (TPS3103 versus TPS3106) does not affect functional equivalence for this voltage classification.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging? A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® packaging provides the same components on shorter tape segments or alternative reel formats, suitable for lower-volume production or manual assembly processes. Electrical and mechanical specifications remain identical.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 Compliant certification with REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity rating, matching the original TPS3106K33MDBVREP specifications.

Q: Which substitute part has the best availability? A: TPS3106K33DBVT offers the highest inventory level at 169,210 units in Cut Tape & Digi-Reel® format, providing optimal availability for immediate procurement.

Q: Is the SOT-23-6 package identical across all parts? A: Yes. All substitute parts use the SOT-23-6 package with surface mount configuration, ensuring mechanical and thermal compatibility without PCB redesign.
