BD6069GUT-E2 Equivalent & Substitute Parts

Part Overview

The BD6069GUT-E2 is an LED driver IC manufactured by ROHM Semiconductor, designed as a single-output DC-DC regulator with step-up (boost) topology. It delivers 270mA switch current from a 2.7V to 5.5V supply to generate 18V output, operating at 1MHz frequency. The device is packaged in 8-WFBGA VCSP60N1 and is optimized for backlight applications.

The BD6069GUT-E2 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or redesign efforts where this component is no longer available from primary sources.

Substitute Part Grouping Explanation

Substitution of the BD6069GUT-E2 is determined by the following critical parameters:

Primary Substitution Criteria:

Topology: Step-Up (Boost) DC-DC regulator
Supply voltage range: 2.7V to 5.5V input compatibility
Output voltage: 18V or configurable to 18V
Output current capability: Minimum 270mA switch current
Frequency: 1MHz operation or compatible switching frequency
Internal switch: Integrated power switch required
Application: LED driver for backlight use
Package type: Surface mount with thermal management capability
Compliance: ROHS3 compliant, MSL 1 or better

Substitute parts are grouped into two categories:

Category A - Direct Parametric Equivalents: Parts with identical or superior electrical specifications across all critical parameters, including supply voltage range, output voltage, current rating, and frequency. These parts maintain full functional compatibility with the original design.

Category B - Functional Alternatives: Parts with step-up boost topology and LED driver capability but with variations in one or more secondary parameters (such as package type, frequency, or current rating). These require design verification before implementation.

Engineering Selection Recommendations

For Direct Replacement (Active Status, Boost Topology):

LM36010YKBR and MIC3289-16YML-TR are active, in-stock alternatives with step-up boost topology and supply voltage ranges compatible with the BD6069GUT-E2. Both are ROHS3 compliant with MSL 1 ratings. LM36010YKBR offers higher current capability (1500mA) and operates at 4MHz, suitable for designs requiring increased output power. MIC3289-16YML-TR maintains 1.2MHz operation with 1200mA current, closer to the original frequency profile. Both require PCB layout verification due to different package geometries.

For Supply-Constrained Applications:

LT3593EDC#TRMPBF matches the original 2.7V–5.5V supply range and 1MHz frequency but delivers only 45mA output current. This part is suitable only for low-power backlight applications where 270mA is not required.

For Extended Supply Range:

MP3305DD-LF-P accepts 2.5V–6V input and generates 36V output at 1.33A, providing design flexibility for higher voltage requirements. Operating frequency is 2.2MHz. This part requires output voltage configuration verification.

Not Recommended for Direct Substitution:

LM2759SD/NOPB uses switched-capacitor topology rather than inductive boost, limiting output voltage to 2V–4V and making it unsuitable for 18V applications. MP2410AGJ-P is a step-down (buck) regulator requiring minimum 4.2V input, incompatible with the 2.7V lower supply limit. LT3477EFE#PBF supports multiple topologies but is a general-purpose regulator requiring extensive design reconfiguration.

Compliance & Certification:

All recommended active alternatives are ROHS3 compliant and REACH unaffected. MSL ratings are 1 (unlimited) for LM36010YKBR, MIC3289-16YML-TR, and LT3593EDC#TRMPBF, matching the original specification.

Frequently Asked Questions (FAQ)

Q: Can LM36010YKBR directly replace BD6069GUT-E2 without circuit modifications?

A: LM36010YKBR is functionally compatible as a step-up boost regulator with matching supply voltage range (2.5V–5.5V). However, the package differs (8-DSBGA vs. 8-WFBGA VCSP60N1), requiring PCB layout redesign. Output voltage is not specified in the datasheet, requiring verification that it can be configured to 18V. Current capability (1500mA) exceeds the original 270mA requirement.

Q: What is the key difference between MIC3289-16YML-TR and the original BD6069GUT-E2?

A: Both are step-up boost LED drivers with 1MHz+ switching frequency and similar supply ranges (2.5V–6.5V vs. 2.7V–5.5V). MIC3289-16YML-TR operates at 1.2MHz and delivers 1200mA, compared to 270mA in the original. The package is 8-MLF (2x2) instead of VCSP60N1, requiring PCB redesign. Output voltage is not specified and must be verified for 18V compatibility.

Q: Why is NJU6050F-TE2 not recommended as a direct substitute?

A: Although NJU6050F-TE2 is a step-up boost regulator with compatible 2.5V–6.5V supply range, it delivers only 20mA output current, far below the 270mA requirement. It is suitable only for ultra-low-power backlight applications. The SOT-23-5 package is significantly smaller than VCSP60N1, indicating a different power class.

Q: Can MP3305DD-LF-P be used if the application requires higher output voltage?

A: MP3305DD-LF-P generates 36V output at 1.33A with 2.5V–6V input range, exceeding the original 18V specification. It is suitable only if the application can tolerate higher output voltage or if the output voltage is externally configured to 18V. The 8-QFN package differs from the original, requiring PCB layout changes.

Q: What does "output voltage not specified" mean in the comparison table?

A: Some regulators, such as LM36010YKBR and MIC3289-16YML-TR, have configurable output voltages determined by external feedback resistors rather than fixed internal settings. The datasheet must be consulted to confirm that 18V output can be achieved within the design constraints.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All active substitute parts listed (LM36010YKBR, MIC3289-16YML-TR, NJU6050F-TE2, MP3305DD-LF-P, LT3593EDC#TRMPBF, LT3477EFE#PBF, LM2759SD/NOPB, MP2410AGJ-P) are ROHS3 compliant and REACH unaffected, matching the original BD6069GUT-E2 certification status.

Q: What is the significance of MSL (Moisture Sensitivity Level)?

A: MSL 1 (unlimited) indicates the component can be stored indefinitely without moisture bake-out requirements before soldering. MSL 3 (168 hours) requires moisture conditioning within 168 hours of package opening. The original BD6069GUT-E2 specifies MSL 1. Most active substitutes maintain MSL 1, ensuring equivalent handling and storage procedures.

Q: Why is package type critical for substitution?

A: Package type determines PCB footprint, thermal management capability, and assembly process compatibility. The original VCSP60N1 (8-WFBGA) is a ball-grid-array package with specific thermal and electrical characteristics. Substitutes with different packages (such as 8-MLF, 8-QFN, or SOT-23) require complete PCB redesign, including trace routing, via placement, and thermal pad configuration.
