TPS3824-30DBVT Equivalent & Substitute Parts

Part Overview

The TPS3824-30DBVT is a single-channel power management supervisor IC manufactured by Texas Instruments, designed for reset and power-on reset applications. This device operates as a push-pull, totem pole output supervisor with a 2.63V voltage threshold and 120ms minimum reset timeout. The part is currently in Last Time Buy status, indicating end-of-life production. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain supply chain reliability for new production runs or design revisions.

Substitute Part Grouping Explanation

Substitute parts for the TPS3824-30DBVT are identified based on strict parametric equivalence across the following critical criteria:

Mandatory Matching Parameters:

• Package / Case: SC-74A, SOT-753
• Supplier Device Package: SOT-23-5
• Type: Simple Reset/Power-On Reset
• Number of Voltages Monitored: 1
• Voltage - Threshold: 2.63V
• Output: Push-Pull, Totem Pole
• Reset: Active High/Active Low
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowed Variation Parameters:

• Reset Timeout: Minimum 120ms (equal or greater values acceptable)
• Operating Temperature: Minimum range -40°C ~ 85°C (extended ranges acceptable)
• Packaging Format: Tape & Reel (TR), Cut Tape (CT), or Digi-Reel® formats
• Product Status: Active or Last Time Buy
• Manufacturer: Different manufacturers permitted if all electrical and mechanical parameters match

Parameter Comparison

Engineering Selection Recommendations

TPS3824-30DBVR (Parametric Equivalent): This part is the direct parametric equivalent from Texas Instruments, matching all critical electrical and mechanical specifications. The primary distinction is packaging format (Cut Tape and Digi-Reel® versus Tape & Reel) and product status (Active versus Last Time Buy). This part is recommended as the primary substitute for the TPS3824-30DBVT due to identical functional parameters and active production status.

MAX824REUK+T (Manufacturer-Recommended Equivalent): This part meets all mandatory parametric requirements with two allowable variations: reset timeout of 140ms (exceeds the 120ms minimum requirement) and extended operating temperature range of -40°C ~ 125°C (exceeds the -40°C ~ 85°C requirement). Both variations represent enhanced specifications suitable for applications requiring extended thermal performance. This part is manufactured by Analog Devices Inc./Maxim Integrated and carries active product status. Selection of this part is appropriate when extended temperature range operation is beneficial to system design.

Both substitute parts carry ROHS3 compliance and REACH Unaffected status, matching the original part's regulatory certifications.

Frequently Asked Questions (FAQ)

Q: Can TPS3824-30DBVR be used as a direct replacement for TPS3824-30DBVT?

A: Yes. The TPS3824-30DBVR is a parametric equivalent with identical electrical and mechanical specifications. The difference in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) does not affect circuit-level functionality. Verify packaging compatibility with your assembly process requirements.

Q: What are the differences between TPS3824-30DBVR and MAX824REUK+T?

A: Both parts are functionally equivalent at the 2.63V threshold with identical package and output characteristics. The MAX824REUK+T offers a longer reset timeout (140ms versus 120ms) and extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C). These represent enhanced specifications rather than limitations. Select MAX824REUK+T if your application requires operation at temperatures above 85°C or if the longer reset timeout is compatible with system timing requirements.

Q: Why is the TPS3824-30DBVT in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer has discontinued production. Both substitute parts (TPS3824-30DBVR and MAX824REUK+T) are in Active production status, ensuring long-term supply chain availability.

Q: Are there any compatibility concerns when switching from TPS3824-30DBVT to either substitute?

A: No compatibility concerns exist at the circuit level. All three parts share identical package (SOT-23-5), pinout, voltage threshold (2.63V), output type (push-pull, totem pole), and reset logic (active high/active low). Verify PCB footprint compatibility with SC-74A, SOT-753 package specifications.

Q: Which substitute should I select for new designs?

A: For new designs, TPS3824-30DBVR is recommended as the primary choice due to identical specifications and Texas Instruments manufacturing continuity. MAX824REUK+T is appropriate if extended temperature range (-40°C ~ 125°C) provides system-level benefits or if longer reset timeout (140ms) aligns with application timing requirements.
