TPS3823-30DBVT Equivalent & Substitute Parts

Part Overview

The TPS3823-30DBVT is a single-channel power management supervisor IC manufactured by Texas Instruments, designed for push-pull, totem pole reset output applications. This device monitors a 2.63V threshold voltage and provides active-low reset control with a 120ms minimum 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 and long-term support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS3823-30DBVT is determined by the following critical parameters:

• Single-channel voltage monitoring capability
• 2.63V threshold voltage
• Push-pull, totem pole output configuration
• Active-low reset polarity
• Reset timeout of 120ms minimum or greater
• Operating temperature range of -40°C to 85°C minimum
• Surface mount packaging in SOT-23-5 or compatible footprint (SC-74A, SOT-753)
• ROHS3 compliance and REACH unaffected status

Parts are grouped into three categories: parametric equivalents (identical specifications from the same manufacturer), manufacturer-recommended alternatives (functionally equivalent from different manufacturers with minor parameter variations), and obsolete variants (same specifications but end-of-life status).

Parameter Comparison

Engineering Selection Recommendations

For new production designs, TPS3823-30DBVR is the primary parametric equivalent from Texas Instruments, offering identical electrical specifications with active product status and unlimited moisture sensitivity rating. This part maintains full compatibility with existing designs while ensuring long-term availability.

For designs requiring extended operating temperature range (-40°C to 125°C), MAX6316LUK26CY+T and MAX6823RUK+T from Analog Devices Inc./Maxim Integrated provide equivalent functionality with enhanced thermal performance. Both parts maintain the required 2.63V threshold, active-low reset, and push-pull output configuration.

APX823-26W5G-7 from Diodes Incorporated is functionally equivalent with active product status but features a longer reset timeout (140ms minimum versus 120ms) and higher moisture sensitivity level (MSL 3). This part is suitable for applications where the extended timeout and MSL rating do not present constraints.

TPS3823-30DBVRG4 shares identical electrical specifications with the main part but carries obsolete product status, limiting its suitability for new designs despite current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can TPS3823-30DBVR be used as a direct replacement for TPS3823-30DBVT?

A: Yes. TPS3823-30DBVR is a parametric equivalent with identical voltage threshold (2.63V), reset timeout (120ms minimum), output configuration (push-pull, totem pole), and operating temperature range (-40°C to 85°C). The primary difference is product status: TPS3823-30DBVR is active, while TPS3823-30DBVT is Last Time Buy. Both use SOT-23-5 packaging.

Q: What is the difference between the Texas Instruments and Maxim Integrated options?

A: Texas Instruments parts (TPS3823 series) and Maxim Integrated parts (MAX6316, MAX6823) are functionally equivalent at the 2.63V threshold with identical output topology. Maxim parts offer extended operating temperature to 125°C versus 85°C for Texas Instruments. Reset timeout is 120ms minimum for TPS3823 variants and 140ms minimum for Maxim variants. Both manufacturers' parts meet ROHS3 and REACH requirements.

Q: Is APX823-26W5G-7 compatible with designs using TPS3823-30DBVT?

A: APX823-26W5G-7 is functionally compatible with matching voltage threshold (2.63V), output type (push-pull, totem pole), and reset polarity (active low). The reset timeout is 140ms minimum, which is longer than the 120ms minimum of TPS3823-30DBVT. The part uses SOT-25 packaging instead of SOT-23-5, requiring PCB footprint verification. Moisture sensitivity is MSL 3 (168 hours) versus MSL 1 (unlimited) for the original part.

Q: Why is TPS3823-30DBVRG4 listed if it is obsolete?

A: TPS3823-30DBVRG4 is included for reference as a parametric equivalent with identical specifications to TPS3823-30DBVT. However, its obsolete status makes it unsuitable for new production designs. Existing inventory may be available for legacy system support only.

Q: What packaging considerations apply when selecting a substitute?

A: All listed substitutes use surface mount packaging in the SC-74A, SOT-753 case outline. TPS3823-30DBVT, TPS3823-30DBVR, TPS3823-30DBVRG4, MAX6316LUK26CY+T, and MAX6823RUK+T use SOT-23-5 supplier device package. APX823-26W5G-7 uses SOT-25 supplier device package. Verify PCB footprint compatibility before design implementation.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed parts—TPS3823-30DBVR, TPS3823-30DBVRG4, APX823-26W5G-7, MAX6316LUK26CY+T, and MAX6823RUK+T—are ROHS3 compliant and REACH unaffected, matching the compliance status of TPS3823-30DBVT.
