Substitute Part Grouping Explanation

Substitution of the TPS3824-50DBVT is determined by strict equivalence across the following critical parameters:

• Voltage Threshold: 4.55V (determines reset trigger point)
• Output Configuration: Push-Pull, Totem Pole (determines circuit interface compatibility)
• Reset Logic: Active High/Active Low (determines system reset behavior)
• Reset Timeout: 120ms Minimum (determines power-up sequencing timing)
• Package Type: SOT-23-5 (SC-74A, SOT-753) (determines PCB footprint compatibility)
• Operating Temperature Range: -40°C ~ 85°C (determines environmental suitability)
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected (determines market and application eligibility)

The TPS3824-50DBVR qualifies as a direct substitute based on identical electrical specifications, package configuration, and compliance certifications. The primary distinction is product status: the original part is Last Time Buy, while the substitute is Active production status.

Frequently Asked Questions (FAQ)

Q: Can the TPS3824-50DBVR be used as a direct replacement for the TPS3824-50DBVT in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The TPS3824-50DBVR can be substituted without circuit modification or re-qualification, provided the design does not depend on Last Time Buy inventory constraints.

Q: What is the significance of the product status difference between these parts?

A: The TPS3824-50DBVT is Last Time Buy, indicating Texas Instruments has ceased production and existing inventory is limited. The TPS3824-50DBVR is Active production status, ensuring continued availability for future orders and long-term supply chain reliability.

Q: Are the package dimensions and PCB footprints identical?

A: Yes. Both parts use the SC-74A, SOT-753 package (SOT-23-5), ensuring identical PCB footprint compatibility and no layout modifications are required.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the TPS3824-50DBVT and TPS3824-50DBVR are ROHS3 Compliant and REACH Unaffected, meeting identical environmental and regulatory requirements.

Q: What are the critical electrical parameters that define substitution eligibility?

A: Substitution is determined by matching voltage threshold (4.55V), output configuration (Push-Pull, Totem Pole), reset logic (Active High/Active Low), reset timeout (120ms Minimum), and operating temperature range (-40°C ~ 85°C). All parameters are identical between these parts.

Q: Is there any difference in moisture sensitivity or handling requirements?

A: No. Both parts have Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating identical handling and storage requirements with no special moisture control measures necessary.
