TPS62205DBVRG4 Equivalent & Substitute Parts

Part Overview

The TPS62205DBVRG4 is a buck switching regulator IC from Texas Instruments designed for step-down voltage conversion with a fixed 2.5V output and 300mA current capacity. This device is packaged in SC-74A (SOT-753) form factor and operates across a 2.5V to 6V input range with a 1MHz switching frequency and integrated synchronous rectification.

The TPS62205DBVRG4 is currently discontinued at DiGi Electronics. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS62205DBVRG4 is determined by the following critical parameters:

Primary Matching Criteria:

• Fixed output voltage of 2.5V
• Buck topology with positive output configuration
• Single output
• Surface mount packaging compatible with SOT-23-5 footprint
• Synchronous rectification capability
• RoHS3 compliance

Secondary Compatibility Factors:

• Input voltage range must encompass or exceed 2.5V to 6V
• Output current capacity must meet or exceed 300mA
• Operating temperature range must cover -40°C to 85°C minimum
• Switching frequency and MSL rating are non-critical for substitution

Two substitute parts meet these criteria with varying performance characteristics and availability status.

Parameter Comparison

Engineering Selection Recommendations

TPS62205DBVR (Texas Instruments): This part is the direct equivalent from the same manufacturer with identical electrical specifications and package form factor. It maintains the same input voltage range, output current rating, and switching frequency as the discontinued TPS62205DBVRG4. The TPS62205DBVR is currently in active production status with 23,200 units in stock, making it the primary replacement option. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel), which does not affect electrical performance or PCB compatibility.

ADP2108AUJZ-2.5-R7 (Analog Devices Inc.): This part provides functional equivalence with enhanced performance characteristics. It delivers double the output current capacity (600mA versus 300mA) and operates across a wider temperature range (-40°C to 125°C). The input voltage range is slightly narrower (2.3V to 5.5V) but remains compatible with typical 2.5V to 6V applications. The switching frequency is higher at 3MHz. This device is in active production with 4,290 units in stock. The package designation differs (TSOT-23-5 versus SOT-753), though both are SOT-23-5 footprint variants suitable for the same PCB layout.

Both substitutes carry ROHS3 compliance and unlimited moisture sensitivity ratings, matching the original part's environmental certifications.

Frequently Asked Questions (FAQ)

Q: Can TPS62205DBVR be used as a direct replacement for TPS62205DBVRG4?

A: Yes. The TPS62205DBVR is electrically and functionally identical to the TPS62205DBVRG4. Both devices share the same output voltage (2.5V), output current (300mA), input voltage range (2.5V to 6V), switching frequency (1MHz), and package form factor (SC-74A, SOT-753). The only difference is the packaging format supplied by the distributor. No circuit modifications are required.

Q: What are the key differences between TPS62205DBVR and ADP2108AUJZ-2.5-R7?

A: Both parts provide 2.5V fixed output with synchronous buck regulation. The ADP2108AUJZ-2.5-R7 offers higher output current capacity (600mA versus 300mA), higher switching frequency (3MHz versus 1MHz), and extended operating temperature range (-40°C to 125°C versus -40°C to 85°C). The input voltage range is slightly narrower (2.3V to 5.5V versus 2.5V to 6V). Both use SOT-23-5 footprint variants compatible with the same PCB layout.

Q: Are the package variants (SOT-753 versus TSOT-23-5) interchangeable on the PCB?

A: Both SC-74A (SOT-753) and TSOT-23-5 are SOT-23-5 footprint variants with identical pin spacing and layout. They are mechanically and electrically interchangeable on standard PCB designs. The "T" designation in TSOT-23-5 indicates a thinner profile, which may be beneficial in space-constrained applications but does not affect electrical compatibility.

Q: Which substitute should be selected for new designs?

A: Selection depends on application requirements. For direct replacement with identical specifications, use TPS62205DBVR. For applications requiring higher output current capacity or extended temperature operation, use ADP2108AUJZ-2.5-R7. Both parts are in active production with adequate inventory availability.

Q: Do the substitute parts maintain RoHS3 compliance?

A: Yes. Both TPS62205DBVR and ADP2108AUJZ-2.5-R7 are ROHS3 compliant with unlimited moisture sensitivity levels (MSL 1), matching the environmental certifications of the original TPS62205DBVRG4.
