Engineering Selection Recommendations

All listed substitute parts are parametrically equivalent to the TPS64201DBVRG4 and maintain full functional compatibility. Selection among substitutes should be based on the following factors:

Product Status: All substitute parts carry Active product status, ensuring long-term availability and manufacturing support compared to the discontinued TPS64201DBVRG4.

Compliance & Certifications: All substitutes maintain ROHS3 compliance, REACH Unaffected status, and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental and regulatory qualifications.

Packaging Format: Choose based on assembly requirements. Cut Tape (CT) & Digi-Reel® format (TPS64200DBVR) suits lower-volume or manual assembly operations. Tape & Reel (TR) format suits automated pick-and-place assembly at production scale.

Inventory Availability: TPS64201DBVR offers the highest inventory level (36,100 pcs), providing supply security for high-volume production. TPS64203DBVR (13,180 pcs) and TPS64202DBVR (9,700 pcs) provide alternative sources with substantial stock.

Frequently Asked Questions (FAQ)

Q: Are all listed parts electrically identical to the TPS64201DBVRG4?

A: Yes. All substitute parts maintain identical electrical specifications including supply voltage range (1.8V ~ 6.5V), output configuration (positive or negative), topology (buck), duty cycle (100% maximum), and operating temperature range (-40°C ~ 85°C). Functional equivalence is complete.

Q: What is the difference between DBVR and DBVT packaging designations?

A: The suffix indicates packaging format. DBVR denotes Cut Tape (CT) & Digi-Reel® format suitable for lower-volume assembly. DBVT denotes Tape & Reel (TR) format optimized for automated high-volume production. Both use identical SOT-23-6 package geometry with no functional difference.

Q: Why is the TPS64201DBVRG4 listed as discontinued?

A: The original part number is discontinued at DiGi Electronics. However, parametrically equivalent variants within the TPS642xx family (TPS64200, TPS64201, TPS64202, TPS64203) remain in active production, ensuring design continuity and supply availability.

Q: Can I substitute any of these parts interchangeably in my design?

A: Yes, within the constraints of your assembly process. All parts are pin-compatible in SOT-23-6 package and electrically equivalent. Select the packaging format (Cut Tape or Tape & Reel) that matches your manufacturing capability.

Q: Do all substitutes meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 compliant, REACH Unaffected, and carry MSL Level 1 (Unlimited) rating, matching the original part's regulatory and environmental qualifications.

Q: Which substitute offers the best availability?

A: TPS64201DBVR provides the highest inventory level at 36,100 pcs in Tape & Reel format, making it the optimal choice for high-volume production requiring supply security.
