TPS3514DR Equivalent & Substitute Parts

Part Overview

The TPS3514DR is a multi-voltage supervisor IC from Texas Instruments designed for power management applications. This 3-channel supervisor monitors multiple voltage rails (3.3V, 5V, 12V) and provides active-low reset output with open-drain or open-collector configuration. The device is currently in Last Time Buy status, making identification of equivalent and substitute parts essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TPS3514DR is determined by the following critical parameters:

Parametric Equivalents require matching specifications across all monitored voltage channels, threshold values, output type, reset logic, reset timeout duration, and package form factor. The TPS3513DR meets these criteria as a direct parametric equivalent.

Functional Alternatives may differ in channel count, voltage thresholds, or package type while maintaining the same output behavior and reset characteristics. The TPS3808G01DBVR operates as a functional alternative with reduced channel count (1 channel) and different package configuration (SOT-23-6), suitable for applications requiring single-voltage supervision.

Parameter Comparison

Engineering Selection Recommendations

TPS3513DR is the recommended parametric equivalent for direct replacement in existing designs. It maintains identical voltage monitoring channels (3.3V, 5V, 12V), package form factor (14-SOIC), reset characteristics (200ms minimum timeout, active-low logic), and operating temperature range. Both devices share Last Time Buy status, indicating similar lifecycle positioning. This part is suitable for applications requiring no design modification.

TPS3808G01DBVR is classified as a functional alternative for applications where single-voltage supervision is sufficient. This part operates in Active product status, providing extended availability compared to Last Time Buy devices. The SOT-23-6 package requires PCB layout modification. The adjustable/selectable voltage threshold and reset timeout provide design flexibility for applications not requiring fixed multi-voltage monitoring. Operating temperature range extends to 125°C (TJ), supporting higher thermal environments.

All substitute parts maintain ROHS3 compliance, open-drain/open-collector output configuration, and active-low reset logic consistent with the TPS3514DR.

Frequently Asked Questions (FAQ)

Q: Can TPS3513DR replace TPS3514DR without design changes? A: Yes. The TPS3513DR is a parametric equivalent with identical voltage thresholds (3.3V, 5V, 12V), package (14-SOIC), reset timeout (200ms minimum), and operating temperature range (-40°C to 85°C). No PCB or schematic modifications are required.

Q: When should TPS3808G01DBVR be considered as a substitute? A: The TPS3808G01DBVR is suitable for applications requiring single-voltage supervision only. It requires PCB redesign due to different package (SOT-23-6 versus 14-SOIC) and offers adjustable voltage thresholds and reset timeout. This part is recommended for new designs or redesigns where single-channel monitoring meets system requirements.

Q: What is the impact of Last Time Buy status on these parts? A: Last Time Buy status indicates limited future availability. Both TPS3514DR and TPS3513DR are in this status. For long-term supply assurance, TPS3808G01DBVR (Active status) provides extended procurement windows, though it requires design modification for single-channel applications.

Q: Are all substitute parts RoHS compliant? A: Yes. TPS3514DR, TPS3513DR, and TPS3808G01DBVR are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting environmental and reliability standards.

Q: How do package differences affect substitution? A: TPS3514DR and TPS3513DR use identical 14-SOIC packages and are pin-compatible. TPS3808G01DBVR uses SOT-23-6 package, requiring PCB layout and footprint changes. Package selection depends on available board space and design constraints.

Q: What are the voltage monitoring differences between these parts? A: TPS3514DR and TPS3513DR monitor three fixed voltage rails (3.3V, 5V, 12V). TPS3808G01DBVR monitors one voltage rail with adjustable/selectable threshold, providing flexibility for custom voltage monitoring but reduced multi-rail capability.
