TPS3840PL29DBVR Equivalent & Substitute Parts

Part Overview

The TPS3840PL29DBVR is an active Power Management Integrated Circuit (PMIC) functioning as a supervisor with single-channel voltage monitoring and push-pull output configuration. This device is designed for reset and power-on reset applications in systems requiring precise voltage threshold detection. The part is in active product status and RoHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical characteristics are required for design flexibility, inventory management, or supply chain optimization while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the TPS3840PL29DBVR is determined by strict equivalence of the following critical parameters:

• Voltage Threshold: 2.9V (exact match required)
• Number of Voltages Monitored: 1 channel
• Output Configuration: Push-Pull, Totem Pole
• Reset Logic: Active Low
• Reset Timeout: 619ms Typical
• Package / Case: SC-74A, SOT-753 (SOT-23-5)
• Operating Temperature Range: -40°C to 125°C (TJ)
• Mounting Type: Surface Mount

The substitute part TPS3840PL29DBVRQ1 meets all these critical electrical and mechanical parameters. The primary difference is the automotive qualification (AEC-Q100 grade), which represents an additional level of qualification beyond the standard industrial specification and does not preclude substitution for non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS3840PL29DBVR and TPS3840PL29DBVRQ1 are active products from Texas Instruments and are RoHS3 compliant with REACH unaffected status. The TPS3840PL29DBVR is suitable for standard industrial applications, while the TPS3840PL29DBVRQ1 carries automotive qualification (AEC-Q100) and is appropriate for automotive-grade system requirements. Selection between these parts should be based on application requirements and regulatory compliance needs. Both parts maintain identical electrical performance and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Are TPS3840PL29DBVR and TPS3840PL29DBVRQ1 electrically equivalent?

A: Yes. Both parts are electrically identical with matching voltage threshold (2.9V), output configuration (push-pull, totem pole), reset logic (active low), and reset timeout (619ms typical). All electrical specifications are equivalent.

Q: What is the difference between these two parts?

A: The TPS3840PL29DBVRQ1 includes automotive-grade qualification (AEC-Q100), while the TPS3840PL29DBVR is specified for standard industrial applications. Both are manufactured by Texas Instruments and use identical SOT-23-5 packaging.

Q: Can I substitute TPS3840PL29DBVRQ1 for TPS3840PL29DBVR in an industrial application?

A: Yes. The automotive-qualified version contains no restrictions that would prevent its use in industrial applications. The additional automotive qualification does not reduce functionality or performance for non-automotive use cases.

Q: Can I substitute TPS3840PL29DBVR for TPS3840PL29DBVRQ1 in an automotive application?

A: No. Automotive applications requiring AEC-Q100 qualification must use TPS3840PL29DBVRQ1. The standard industrial version does not carry automotive qualification.

Q: Are the packages identical?

A: Yes. Both parts use SC-74A / SOT-753 package format with SOT-23-5 supplier device packaging. Surface mounting and land pattern requirements are identical, allowing direct PCB substitution.

Q: What is the Moisture Sensitivity Level (MSL) for both parts?

A: Both parts are classified as MSL 1 (Unlimited), requiring no special moisture control during storage or handling.

Q: Are both parts RoHS3 compliant?

A: Yes. Both TPS3840PL29DBVR and TPS3840PL29DBVRQ1 are RoHS3 compliant with REACH unaffected status.
