TPS62021DRCRG4 Equivalent & Substitute Parts

Part Overview

The TPS62021DRCRG4 is a buck switching regulator IC from Texas Instruments designed for positive adjustable output applications. It delivers 600mA output current with an input voltage range of 2.5V to 6V and adjustable output from 0.7V to 6V. The device operates at 1.25MHz switching frequency with integrated synchronous rectification in a 10-VFDFN exposed pad surface mount package.

This part is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and replacement applications.

Substitute Part Grouping Explanation

Substitution of the TPS62021DRCRG4 is determined by strict equivalence across the following critical parameters:

Topology: Buck switching regulator
Output configuration: Positive adjustable
Voltage specifications: Input 2.5V–6V, Output 0.7V–6V adjustable
Current rating: 600mA output
Switching frequency: 1.25MHz
Synchronous rectification: Integrated
Package: 10-VFDFN exposed pad (10-VSON 3x3)
Temperature range: -40°C to 85°C
Compliance: ROHS3, REACH Unaffected

The TPS62021DRCR meets all these criteria and qualifies as a direct substitute. The primary difference is packaging format: the original part (TPS62021DRCRG4) is supplied in cut tape, while the substitute (TPS62021DRCR) is supplied in tape and reel format. Both use identical die and electrical specifications.

Engineering Selection Recommendations

The TPS62021DRCR is a direct electrical and mechanical equivalent to the TPS62021DRCRG4. Both parts share identical die specifications, electrical performance, and package geometry. The substitute maintains full compliance with ROHS3 and REACH requirements.

The primary consideration for selection is packaging format. The original part is supplied in cut tape format, while the substitute is supplied in tape and reel format. For production environments requiring reel quantities, the TPS62021DRCR offers superior handling and automated assembly compatibility. For applications requiring smaller quantities or manual assembly, cut tape format may be preferred, but the substitute remains electrically and mechanically interchangeable.

The active product status of TPS62021DRCR ensures continued availability and supply chain stability compared to the discontinued original part.

Frequently Asked Questions (FAQ)

Q: Are the TPS62021DRCRG4 and TPS62021DRCR electrically identical?

A: Yes. Both parts use the same die and share identical electrical specifications across all parameters including input voltage range (2.5V–6V), adjustable output (0.7V–6V), output current (600mA), switching frequency (1.25MHz), and operating temperature range (-40°C to 85°C).

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

A: The difference is packaging format only. TPS62021DRCRG4 is supplied in cut tape, while TPS62021DRCR is supplied in tape and reel format. The physical package (10-VSON 3x3) and pin configuration are identical.

Q: Can I use TPS62021DRCR as a direct replacement in my design?

A: Yes. The substitute is mechanically and electrically compatible. No circuit modifications or PCB layout changes are required. Tape and reel packaging is compatible with standard pick-and-place assembly equipment.

Q: Does the substitute maintain the same compliance certifications?

A: Yes. TPS62021DRCR is ROHS3 compliant and REACH unaffected, matching the original part's compliance status.

Q: Why is the original part discontinued?

A: Product discontinuation decisions are made by manufacturers based on market demand and product lifecycle management. The active substitute ensures design continuity without requiring circuit redesign.

Q: Are there inventory differences between these parts?

A: Yes. TPS62021DRCRG4 has 2300 pcs in stock, while TPS62021DRCR has 9200 pcs in stock, providing greater availability for the substitute.
