TPS3124J18DBVT Equivalent & Substitute Parts

Part Overview

The TPS3124J18DBVT is a single-channel power management supervisor IC manufactured by Texas Instruments, designed for reset and power-on reset applications. This Surface Mount device operates across the industrial temperature range of -40°C to 85°C and features push-pull, totem pole output configuration with active high/active low reset capability. The part is classified as Last Time Buy, indicating limited future availability. Equivalent and substitute parts are necessary to ensure design continuity and procurement flexibility when the primary part reaches end-of-life status.

Substitute Part Grouping Explanation

Substitution of the TPS3124J18DBVT is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

  • Single-channel voltage monitoring capability
  • 1.62V voltage threshold
  • Push-pull, totem pole output configuration
  • Active high/active low reset capability
  • 100ms minimum reset timeout
  • Operating temperature range: -40°C to 85°C
  • Surface mount technology with SOT-23-5 package
  • ROHS3 compliance and REACH unaffected status

Packaging Flexibility: Substitution is permitted between Cut Tape (CT) and Tape & Reel (TR) packaging formats, as these represent distribution methods for the same electrical component. The SC-74A, SOT-753 physical package remains constant across all equivalent parts.

Base Product Number Variations: The TPS3124 and TPS3125 base product numbers represent distinct part families within the Texas Instruments supervisor IC portfolio. Parts sharing identical electrical specifications and package configurations are classified as parametric equivalents regardless of base product designation.

Engineering Selection Recommendations

All substitute parts maintain full electrical and mechanical compatibility with the TPS3124J18DBVT. Selection among equivalent parts should be based on the following factors:

Product Status Consideration: The TPS3125J18DBVR carries Active product status, indicating ongoing manufacturer support and extended availability compared to Last Time Buy designations. For new designs or long-term production requirements, TPS3125J18DBVR is the preferred selection.

Packaging Format: Choose Tape & Reel (TR) format for high-volume automated assembly operations. Select Cut Tape (CT) or Digi-Reel® formats for lower-volume applications or manual assembly processes.

Compliance Verification: All listed parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can TPS3124J18DBVR be used as a direct replacement for TPS3124J18DBVT? A: Yes. Both parts are electrically identical with 1.62V threshold, push-pull totem pole output, and 100ms reset timeout. The difference is packaging format: Cut Tape versus Tape & Reel. Physical package remains SC-74A, SOT-23-5.

Q: What is the difference between TPS3124 and TPS3125 base product numbers? A: Both base product families meet the specified electrical parameters for this application. They are distinct part families within the Texas Instruments supervisor IC portfolio but are parametrically equivalent for single-channel, 1.62V threshold reset applications.

Q: Is TPS3125J18DBVR recommended over other substitutes? A: TPS3125J18DBVR carries Active product status, providing extended manufacturer support and availability compared to Last Time Buy parts. For procurement planning, this part offers superior long-term supply assurance.

Q: Are there any temperature or compliance differences between substitute parts? A: No. All parts operate across -40°C to 85°C, maintain ROHS3 compliance, and carry REACH unaffected status. Environmental and regulatory specifications are identical.

Q: Can packaging formats be mixed in the same design? A: Yes. Cut Tape, Tape & Reel, and Digi-Reel® formats contain identical electrical components in the same physical package. Format selection depends on assembly process requirements, not electrical compatibility.
