Substitute Part Grouping Explanation

Substitute parts for the TPS3513DR are classified based on functional equivalence and parametric compatibility. The primary substitution criteria are:

Parametric Equivalent Classification: Parts that maintain identical or functionally equivalent specifications across all critical parameters including number of voltage channels monitored, voltage threshold values, output type, reset logic, reset timeout duration, operating temperature range, and package form factor.

Manufacturer Recommended Classification: Parts that provide functional supervision capability but may differ in channel count, voltage threshold configuration, or package type, suitable for applications where design flexibility permits component substitution.

The TPS3514DR qualifies as a parametric equivalent, sharing the same 3-channel architecture, identical voltage thresholds (3.3V, 5V, 12V), matching output and reset characteristics, and identical package specifications. The TPS3808G01DBVR is classified as a manufacturer-recommended alternative, offering single-channel supervision with adjustable voltage thresholds and a different package form factor (SOT-23-6), requiring design-level evaluation for compatibility.

Parameter Comparison

Engineering Selection Recommendations

TPS3514DR (Parametric Equivalent): This part is the direct parametric equivalent for the TPS3513DR. Both devices share identical electrical specifications, voltage monitoring architecture, and package form factor. The TPS3514DR maintains ROHS3 compliance and unlimited MSL rating. Selection of the TPS3514DR requires no design modifications and provides pin-for-pin compatibility. Both parts carry Last Time Buy status, indicating limited future availability.

TPS3808G01DBVR (Manufacturer-Recommended Alternative): This part is recommended by Texas Instruments as a functional alternative. The TPS3808G01DBVR operates across an extended temperature range (-40°C to 125°C) compared to the TPS3513DR (-40°C to 85°C), providing enhanced thermal performance. However, this device monitors only a single voltage channel with adjustable thresholds, contrasting with the fixed 3-channel, fixed-threshold architecture of the TPS3513DR. The TPS3808G01DBVR uses a smaller SOT-23-6 package, requiring PCB layout modifications. This part maintains Active product status, ensuring long-term availability. Selection of the TPS3808G01DBVR is appropriate for applications where single-channel supervision is sufficient or where design flexibility permits threshold reconfiguration.

Frequently Asked Questions (FAQ)

Q: Can the TPS3514DR be used as a direct replacement for the TPS3513DR?

A: Yes. The TPS3514DR is a parametric equivalent with identical electrical specifications, voltage thresholds, output configuration, reset characteristics, and 14-SOIC package form factor. No design modifications are required for pin-for-pin substitution.

Q: What are the key differences between the TPS3513DR and TPS3808G01DBVR?

A: The primary differences are: (1) Channel count—TPS3513DR monitors three fixed voltage rails (3.3V, 5V, 12V); TPS3808G01DBVR monitors one adjustable voltage rail; (2) Package form factor—TPS3513DR uses 14-SOIC; TPS3808G01DBVR uses SOT-23-6; (3) Operating temperature—TPS3513DR operates -40°C to 85°C; TPS3808G01DBVR operates -40°C to 125°C; (4) Product status—TPS3513DR is Last Time Buy; TPS3808G01DBVR is Active.

Q: Is the TPS3808G01DBVR suitable for applications requiring three-channel voltage monitoring?

A: No. The TPS3808G01DBVR provides single-channel supervision only. Applications requiring simultaneous monitoring of three independent voltage rails must use a multi-channel supervisor such as the TPS3513DR or TPS3514DR.

Q: What is the impact of the different package types on PCB design?

A: The TPS3513DR and TPS3514DR both use 14-SOIC packages with identical footprints. The TPS3808G01DBVR uses a smaller SOT-23-6 package, requiring different PCB land patterns, trace routing, and component placement. Switching to the TPS3808G01DBVR necessitates PCB redesign.

Q: Are all three parts RoHS compliant?

A: Yes. The TPS3513DR, TPS3514DR, and TPS3808G01DBVR are all ROHS3 compliant with unlimited MSL ratings (Level 1).

Q: What should be considered regarding product lifecycle status?

A: Both the TPS3513DR and TPS3514DR carry Last Time Buy status, indicating limited future availability. The TPS3808G01DBVR maintains Active status, ensuring continued supply and long-term design support. For new designs or long-term production requirements, the TPS3808G01DBVR is the preferred choice if application requirements permit single-channel operation.
