TPS3820-50DBVR Equivalent & Substitute Parts

Part Overview

The TPS3820-50DBVR is a power management integrated circuit functioning as a supervisor with push-pull, totem pole output configuration. This single-channel reset IC monitors a 4.55V voltage threshold and provides active-low reset signaling with a 15ms minimum timeout. The device is housed in a SOT-23-5 surface mount package and is currently in active production status. Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or when design flexibility is required across manufacturing batches while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the TPS3820-50DBVR is determined by strict equivalence across the following critical parameters:

• Voltage threshold: 4.55V
• Output type: Push-Pull, Totem Pole
• Reset logic: Active Low
• Reset timeout: 15ms Minimum
• Operating temperature range: -40°C ~ 85°C (TA)
• Package: SOT-23-5 (SC-74A, SOT-753)
• Mounting type: Surface Mount
• Compliance: ROHS3 Compliant, REACH Unaffected

The TPS3820-50DBVT meets all electrical and mechanical requirements for direct substitution. Both parts share identical base product designation (TPS3820), threshold voltage, output configuration, reset characteristics, temperature rating, and packaging specifications. The primary distinction is product status: the TPS3820-50DBVR maintains active production status, while the TPS3820-50DBVT is designated as Last Time Buy.

Parameter Comparison

Engineering Selection Recommendations

The TPS3820-50DBVR is the preferred selection for new designs and ongoing production due to its active product status, ensuring long-term availability and supply chain stability. The TPS3820-50DBVT serves as a direct electrical and mechanical equivalent and is suitable for substitution in existing designs where inventory of the primary part is unavailable. However, the Last Time Buy designation for the TPS3820-50DBVT indicates limited future availability; procurement should prioritize the TPS3820-50DBVR for applications requiring extended production lifecycles.

Both parts maintain identical ROHS3 compliance and REACH unaffected status, confirming regulatory equivalence for applications subject to environmental and hazardous substance restrictions.

Frequently Asked Questions (FAQ)

Q: Can the TPS3820-50DBVT replace the TPS3820-50DBVR in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including voltage threshold, output configuration, reset logic, temperature rating, and SOT-23-5 packaging. Direct substitution is permissible without circuit modification.

Q: What is the difference between these two part numbers?

A: The TPS3820-50DBVR and TPS3820-50DBVT differ only in product status. The TPS3820-50DBVR is in active production, while the TPS3820-50DBVT is designated Last Time Buy, indicating limited future availability.

Q: Are there any compliance differences between the substitute parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected, confirming identical regulatory status.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Both parts use the SOT-23-5 package with identical pin configuration and electrical characteristics, permitting direct PCB-level substitution without layout or assembly modifications.

Q: Which part should be specified for new product designs?

A: The TPS3820-50DBVR should be specified for new designs due to its active production status and assured long-term availability.
