TPS3824-25DBVT Equivalent & Substitute Parts

Part Overview

The TPS3824-25DBVT 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 2.25V 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 applications requiring this supervisor functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS3824-25DBVT is determined by the following critical parameters:

• Single-channel voltage monitoring capability
• 2.25V voltage threshold setting
• Push-pull, totem pole output configuration
• Active High/Active Low reset capability
• Operating temperature range of -40°C to 85°C
• Surface mount packaging in SC-74A / SOT-753 form factor
• ROHS3 compliance and REACH unaffected status

Parts meeting these criteria are classified as parametric equivalents. Variations in reset timeout duration (120ms minimum vs. 140ms minimum) and packaging format (Tape & Reel vs. Cut Tape) do not disqualify substitution when the core electrical and thermal specifications align.

Parameter Comparison

Engineering Selection Recommendations

TPS3824-25DBVR is the primary parametric equivalent to TPS3824-25DBVT. Both parts are manufactured by Texas Instruments with identical electrical specifications, threshold voltage, output configuration, and operating temperature range. The TPS3824-25DBVR maintains Active product status, ensuring continued availability and supply chain support. The difference in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) does not affect electrical performance or PCB-level compatibility.

APX824-23W5G-7, manufactured by Diodes Incorporated, is a cross-manufacturer substitute meeting all core electrical and thermal requirements. This part maintains the same voltage threshold, output configuration, reset capability, and operating temperature range. The reset timeout specification of 140ms minimum (versus 120ms minimum for the TPS3824 series) represents a longer timeout duration and does not compromise functionality in applications designed for the original 120ms specification. APX824-23W5G-7 is in Active product status with established supply availability.

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

Frequently Asked Questions (FAQ)

Q: Can TPS3824-25DBVR directly replace TPS3824-25DBVT in production?

A: Yes. Both parts share identical electrical specifications, voltage threshold, output configuration, and operating temperature range. The packaging format difference (Cut Tape & Digi-Reel® versus Tape & Reel) does not affect PCB assembly or electrical performance. TPS3824-25DBVR is recommended as the primary replacement due to its Active product status.

Q: What is the impact of the 140ms reset timeout in APX824-23W5G-7 compared to the 120ms minimum in TPS3824-25DBVT?

A: The APX824-23W5G-7 specifies a 140ms minimum reset timeout, which is longer than the 120ms minimum of the original part. This extended timeout does not create incompatibility; applications designed for 120ms operation will function correctly with the longer timeout. Verify that your circuit design does not depend on the reset timeout being exactly 120ms or shorter.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the SC-74A / SOT-753 package form factor with identical pin configurations for single-channel supervisor operation.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is supplied on continuous tape for automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® packaging is pre-cut into smaller quantities for manual or lower-volume assembly. Both formats contain identical components; the difference is in supply format and handling. Verify your assembly process requirements before selecting a packaging format.

Q: Are regulatory certifications identical across all three parts?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, matching the original TPS3824-25DBVT regulatory status.

Q: Why is TPS3824-25DBVT listed as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this specific part number. TPS3824-25DBVR (Active status) and APX824-23W5G-7 (Active status) are recommended for new designs and ongoing production to ensure supply continuity.
