Key Parameters

Substitute Part Grouping Explanation

Substitution for the TPS3825-33DBVT is determined by the following critical parameters:

Primary Compatibility Criteria:

• Single-channel voltage monitoring architecture
• Push-pull, totem pole output configuration
• SOT-23-5 surface mount package (SC-74A, SOT-753)
• Active high reset output capability
• ROHS3 compliance and MSL 1 rating

Substitution Categories:

Parametric Equivalent: TPS3825-33DBVR maintains identical electrical specifications and is manufactured by the same supplier (Texas Instruments). This part shares the same base product number (TPS3825), voltage threshold (2.93V), reset timeout (120ms minimum), and operating temperature range (-40°C ~ 85°C). The primary distinction is product status (Active vs. Last Time Buy) and packaging format (Digi-Reel vs. Cut Tape).

Cross-Manufacturer Alternatives: MAX825REUK+T and MAX825TEUK+T are manufactured by Analog Devices Inc./Maxim Integrated. Both maintain the same package type (SOT-23-5), single-channel architecture, and push-pull output configuration. These parts differ in voltage threshold specifications (2.63V and 3.08V respectively), reset timeout (140ms minimum), operating temperature range (-40°C ~ 125°C), and reset polarity options (Active High/Active Low).

Parameter Comparison

Engineering Selection Recommendations

TPS3825-33DBVR (Recommended Primary Substitute): This part is the direct parametric equivalent with identical electrical specifications and is currently in Active product status. It maintains the same voltage threshold (2.93V), reset timeout (120ms minimum), and operating temperature range as the original TPS3825-33DBVT. Both parts are ROHS3 compliant with MSL 1 rating. Selection of this part eliminates design modification requirements and ensures functional compatibility.

MAX825REUK+T (Cross-Manufacturer Alternative): This Analog Devices part maintains SOT-23-5 packaging and push-pull output configuration with Active product status. The voltage threshold is 2.63V (lower than the original 2.93V), and reset timeout is 140ms minimum (longer than the original 120ms minimum). Operating temperature range extends to 125°C. This part is suitable for applications where the lower voltage threshold and extended temperature range are compatible with system requirements.

MAX825TEUK+T (Cross-Manufacturer Alternative): This Analog Devices part maintains SOT-23-5 packaging and push-pull output configuration with Active product status. The voltage threshold is 3.08V (higher than the original 2.93V), and reset timeout is 140ms minimum (longer than the original 120ms minimum). Operating temperature range extends to 125°C. This part is suitable for applications where the higher voltage threshold and extended temperature range are compatible with system requirements.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can TPS3825-33DBVR be used as a direct replacement for TPS3825-33DBVT?

A: Yes. TPS3825-33DBVR is a parametric equivalent with identical voltage threshold (2.93V), reset timeout (120ms minimum), operating temperature range (-40°C ~ 85°C), and output configuration (push-pull, totem pole). The primary difference is product status (Active vs. Last Time Buy) and packaging format. No design modifications are required.

Q: What are the key differences between TPS3825-33DBVT and the MAX825 series substitutes?

A: The MAX825REUK+T and MAX825TEUK+T differ in three primary parameters: voltage threshold (2.63V and 3.08V respectively, compared to 2.93V), reset timeout (140ms minimum vs. 120ms minimum), and operating temperature range (-40°C ~ 125°C vs. -40°C ~ 85°C). Both maintain the same SOT-23-5 package and push-pull output configuration. Selection depends on whether these parameter variations are compatible with the application circuit design.

Q: Are all substitute parts available in the same packaging format?

A: All parts are available in SOT-23-5 surface mount package (SC-74A, SOT-753). However, packaging format differs: TPS3825-33DBVT and MAX825TEUK+T are supplied in Cut Tape (CT) & Digi-Reel format, while TPS3825-33DBVR is supplied in Cut Tape (CT) & Digi-Reel format, and MAX825REUK+T is supplied in Tape & Reel (TR) format. Verify packaging requirements for your procurement and assembly process.

Q: Do the MAX825 parts support the same reset polarity as the TPS3825-33DBVT?

A: The TPS3825-33DBVT supports Active High reset only. The MAX825REUK+T and MAX825TEUK+T support both Active High and Active Low reset polarity. If your circuit requires Active High reset only, both MAX825 parts are compatible. If your circuit requires Active Low reset, only the MAX825 series provides this capability.

Q: Are all parts ROHS3 compliant?

A: Yes. All listed parts (TPS3825-33DBVT, TPS3825-33DBVR, MAX825REUK+T, and MAX825TEUK+T) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level rating.
