TPS92411PDBVR Equivalent & Substitute Parts

Part Overview

The TPS92411PDBVR is an LED driver IC manufactured by Texas Instruments, designed for AC DC offline switching applications. This single-output power management IC operates across a wide supply voltage range of 7.5V to 94V and supports multiple topologies including Flyback, Step-Down (Buck), and Step-Up (Boost) configurations. The device is housed in a SOT-23-5 surface mount package and is classified as Active product status with full RoHS3 compliance. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct replacement in circuit designs.

Substitute Part Grouping Explanation

Substitute parts for the TPS92411PDBVR are classified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Parametric Equivalents (Texas Instruments TPS92411 Series): Parts TPS92411DBVR, TPS92411DBVT, and TPS92411PDBVT maintain identical functional specifications, topology support, and package form factor. These variants differ only in packaging format (Cut Tape vs. Tape & Reel) and maximum supply voltage tolerance (94V vs. 100V). All three operate within the same temperature range, support identical output configurations, and carry equivalent compliance certifications.

Manufacturer Recommended Substitute (Power Integrations LNK420EG): The LNK420EG represents a cross-manufacturer alternative from Power Integrations. While functionally serving the same LED driver application, this part operates under different electrical constraints (36V to 725V supply range) and uses a different package form (eSIP-7C through-hole vs. SOT-23-5 surface mount). This substitute is applicable only when circuit topology and board layout accommodate the alternative package specification.

Parameter Comparison

Engineering Selection Recommendations

Texas Instruments TPS92411 Series Substitutes (TPS92411DBVR, TPS92411DBVT, TPS92411PDBVT): These parts are direct functional equivalents suitable for drop-in replacement. All maintain Active product status with RoHS3 compliance and identical operating temperature specifications. Selection among these variants depends on packaging format availability: TPS92411DBVR and TPS92411DBVT are supplied in Tape & Reel format with 100V maximum supply rating, while TPS92411PDBVT is supplied in Tape & Reel format with 94V maximum supply rating matching the original TPS92411PDBVR specification.

Power Integrations LNK420EG: This substitute is applicable only when circuit design accommodates the eSIP-7C through-hole package and the extended supply voltage range (36V to 725V). The LNK420EG operates under the LinkSwitch-PH series topology with PWM dimming capability and 4.9A output current specification. This part requires PCB layout modification and is not a direct pin-compatible replacement.

Frequently Asked Questions (FAQ)

Q: Can TPS92411DBVR directly replace TPS92411PDBVR? A: Yes. Both parts share identical electrical specifications, topology support, and SOT-23-5 package form factor. The primary difference is packaging format (Tape & Reel vs. Cut Tape) and maximum supply voltage (100V vs. 94V). For applications operating below 94V, direct substitution is valid.

Q: What is the difference between TPS92411DBVT and TPS92411DBVR? A: Both parts are functionally equivalent with identical electrical specifications and maximum 100V supply rating. The suffix designates internal die or trim variations that do not affect circuit-level performance or package compatibility.

Q: Is LNK420EG a pin-compatible replacement? A: No. The LNK420EG uses an eSIP-7C through-hole package, whereas the TPS92411PDBVR uses a SOT-23-5 surface mount package. Pin count, lead configuration, and board mounting method differ significantly. Circuit redesign is required for substitution.

Q: Which substitute offers the best inventory availability? A: TPS92411DBVR provides the highest inventory level at 203,300 pieces. TPS92411PDBVT offers 20,050 pieces, and TPS92411DBVT offers 2,403 pieces. Inventory levels are subject to change.

Q: Are all substitutes RoHS compliant? A: Yes. All listed substitutes carry RoHS compliance certification (RoHS3 for Texas Instruments parts, RoHS Compliant for Power Integrations LNK420EG). All parts maintain MSL Level 1 moisture sensitivity rating.

Q: Can I use LNK420EG in a design originally specified for TPS92411PDBVR? A: Only if the circuit topology and PCB layout are redesigned to accommodate the through-hole eSIP-7C package and the different electrical operating range (36V to 725V minimum vs. 7.5V minimum). This is not a direct substitution scenario.
