BD6583MUV-E2 Equivalent & Substitute Parts

Part Overview

The BD6583MUV-E2 is a LED Driver Controller IC manufactured by ROHM Semiconductor, designed for backlight applications requiring multi-channel DC-DC boost regulation with integrated PWM and analog dimming control. This component integrates a 6-output step-up converter with 25mA per-channel current capability in a compact 24-pin VQFN package.

The BD6583MUV-E2 carries a "Not For New Designs" product status, indicating that ROHM has discontinued active development and support for this device line. This status necessitates identification of functionally equivalent alternatives for ongoing production requirements, design refreshes, or long-term supply chain planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BD6583MUV-E2 is determined by strict parametric matching across the following critical dimensions:

Electrical Parameters: Supply voltage range (2.7V–22V), output channel count (6), per-channel current rating (25mA), switching frequency (1MHz), and dimming control methodology (Analog and PWM support).

Mechanical Parameters: Package type (24-VFQFN Exposed Pad), surface mount configuration, and thermal operating range (-30°C to 85°C).

Compliance Parameters: RoHS3 compliance status and MSL rating of 1 or better.

A substitute part must match all electrical specifications, maintain package and mounting compatibility, and satisfy or exceed compliance requirements. Deviations in any critical parameter disqualify a part from direct substitution.

Engineering Selection Recommendations

The BD6583MUV-E2 is classified as "Not For New Designs" by ROHM Semiconductor. This status reflects the manufacturer's decision to discontinue active support and development for this product line. For applications currently using this device, component selection must account for this lifecycle status.

The part maintains full RoHS3 compliance and carries an MSL rating of 1, indicating no moisture sensitivity constraints during storage and handling. These compliance attributes remain valid for the specified operating temperature range of -30°C to 85°C.

When evaluating alternatives, prioritize parts that maintain identical electrical specifications (6-output boost topology, 25mA per-channel current, 1MHz switching frequency, dual dimming control modes) and package compatibility (24-VFQFN Exposed Pad). Compliance certifications must meet or exceed the original part's RoHS3 and REACH status.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the BD6583MUV-E2?

A: A substitute must match all electrical parameters (6 outputs, 25mA per channel, 1MHz frequency, Analog and PWM dimming), use the identical 24-VFQFN Exposed Pad package, support the 2.7V–22V supply range, and maintain RoHS3 compliance with MSL rating of 1 or better.

Q: Why is the BD6583MUV-E2 marked "Not For New Designs"?

A: This status indicates ROHM has concluded active development and support for this product line. Existing inventory remains available, but the manufacturer does not recommend this part for new circuit designs or long-term production commitments.

Q: Can I use a different package variant of the BD6583 series?

A: No. Package compatibility is a strict substitution requirement. The 24-VFQFN Exposed Pad package is specific to this device. Alternative packages, even within the same base product family, are not direct substitutes due to mechanical and thermal differences.

Q: Does the MSL rating affect substitution eligibility?

A: Yes. The original part carries MSL 1 (Unlimited), indicating no moisture sensitivity. A substitute must maintain this rating or better. Higher MSL ratings introduce storage and handling constraints that may not be compatible with existing supply chain processes.

Q: Are there any compliance considerations for substitution?

A: The BD6583MUV-E2 is ROHS3 compliant and REACH unaffected. Substitute parts must maintain or exceed these compliance standards. Any deviation in regulatory status may require design review and documentation updates.
