TPS73725DCQRG4 Equivalent & Substitute Parts

Part Overview

The TPS73725DCQRG4 is a linear voltage regulator IC from Texas Instruments designed for positive fixed 2.5V output at 1A current capacity in SOT-223-6 surface mount packaging. This part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support, production continuity, and system maintenance. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives with acceptable parameter variations within the allowed tolerance range for this power management category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS73725DCQRG4 is determined by the following critical parameters: fixed output voltage of 2.5V, 1A output current capability, maximum input voltage of 5.5V, and operating temperature range of -40°C to 125°C. All identified substitutes maintain these core electrical specifications. Packaging differences are permitted when mechanical constraints allow, provided the substitute part is surface mount and functionally compatible with the application circuit. The substitution logic prioritizes active product status and current manufacturing availability to ensure long-term supply chain viability.

Parameter Comparison

Engineering Selection Recommendations

The TPS73725DCQR is the primary parametric equivalent, maintaining identical electrical performance and package configuration (SOT-223-6) with active product status and higher current inventory availability. This part is the direct replacement for the obsolete TPS73725DCQRG4 when package footprint compatibility is required.

The TLV75725PDBVR is the manufacturer-recommended substitute, offering active product status and superior moisture sensitivity rating (MSL 1 vs. MSL 2). This part operates within acceptable electrical parameter ranges with a slightly higher dropout voltage (0.65V vs. 0.5V @ 1A). The package change from SOT-223-6 to SOT-23-5 requires PCB layout modification but provides a more compact footprint. Selection of this substitute is appropriate when board space optimization is a design priority and the increased dropout voltage does not compromise system performance.

Both substitutes are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can TPS73725DCQR be used as a direct replacement for TPS73725DCQRG4?

A: Yes. The TPS73725DCQR is a parametric equivalent with identical electrical specifications and SOT-223-6 packaging. No circuit modifications are required. The primary difference is product status (active vs. obsolete) and packaging format (Digi-Reel vs. original packaging).

Q: What is the key difference between TLV75725PDBVR and TPS73725DCQRG4?

A: The TLV75725PDBVR maintains the same output voltage (2.5V), output current (1A), and operating temperature range. The dropout voltage is 0.65V @ 1A compared to 0.5V @ 1A for the original part. The package is SOT-23-5 instead of SOT-223-6, requiring PCB layout changes. The TLV75725PDBVR has superior moisture sensitivity (MSL 1 unlimited vs. MSL 2 one year).

Q: Is package change from SOT-223-6 to SOT-23-5 acceptable?

A: Package change is acceptable only if the application PCB can accommodate the different footprint and pin configuration. SOT-23-5 is physically smaller than SOT-223-6. Verify pin assignments and thermal requirements before implementation.

Q: What is the impact of the 0.15V higher dropout voltage in TLV75725PDBVR?

A: The increased dropout voltage (0.65V vs. 0.5V @ 1A) requires a higher minimum input voltage to maintain stable 2.5V output at full load. Verify that the application input voltage margin remains adequate for the intended operating conditions.

Q: Are all substitutes RoHS and REACH compliant?

A: Yes. All listed parts (TPS73725DCQRG4, TLV75725PDBVR, and TPS73725DCQR) are ROHS3 compliant and REACH unaffected.
