BD9006F-E2 Equivalent & Substitute Parts

Part Overview

The BD9006F-E2 is a buck switching regulator IC manufactured by ROHM Semiconductor, designed for positive adjustable output applications. This device operates as a step-down converter with a single adjustable output delivering 2A maximum current. The BD9006F-E2 carries a "Not For New Designs" product status, indicating it has been superseded in ROHM's product portfolio. Finding equivalent substitute parts is necessary for ongoing production support, maintenance applications, and designs requiring compatible drop-in replacements with equivalent or enhanced electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BD9006F-E2 is determined by compatibility across the following critical parameters:

Functional Equivalence: All substitute parts must operate as buck switching regulators with positive adjustable output configuration and single output topology.

Electrical Compatibility: Input voltage range, output voltage range, and output current capacity define substitution viability. The BD9006F-E2 accepts 7V to 35V input and delivers adjustable output from 0.8V to 35V at 2A maximum. Substitute parts must support these voltage ranges and equal or exceed the 2A current rating.

Switching Frequency: Operating frequency range of 50kHz to 500kHz establishes the baseline. Substitute parts with equivalent or higher frequency capability maintain design compatibility.

Thermal Performance: Operating temperature range of -40°C to 105°C defines the thermal envelope. Substitute parts with equal or extended temperature ranges ensure reliability across application conditions.

Package and Mounting: Surface mount 8-SOIC packages with compatible pinout and thermal characteristics enable direct board-level substitution.

Compliance and Status: RoHS3 compliance and MSL rating of 1 are maintained across all substitute options.

Engineering Selection Recommendations

BD90620EFJ-CE2: This part is the primary substitute for the BD9006F-E2. It maintains active product status within ROHM's portfolio and provides enhanced electrical performance with 2.5A output current capacity versus the original 2A rating. The input voltage minimum is reduced to 5V, expanding application flexibility. Operating temperature extends to 125°C, providing superior thermal margin. The part carries AEC-Q100 automotive qualification, indicating compliance with automotive reliability standards. The package footprint is slightly reduced (0.154" versus 0.173" width) with an exposed pad for improved thermal dissipation. This configuration supports direct substitution in applications where the enhanced current capacity and extended temperature range are beneficial or neutral.

BD90620UEFJ-CE2: This part offers the widest input voltage range, accepting 4.6V minimum input, and extends switching frequency capability to 600kHz. It maintains 2.5A output current and 125°C maximum operating temperature. This variant is suitable for applications requiring lower input voltage operation or higher switching frequency performance. The package configuration matches BD90620EFJ-CE2 with exposed pad thermal enhancement.

Both substitute parts are manufactured by ROHM Semiconductor, maintain ROHS3 compliance and MSL rating of 1, and operate as buck switching regulators with positive adjustable output. Selection between BD90620EFJ-CE2 and BD90620UEFJ-CE2 depends on specific input voltage requirements and switching frequency constraints of the target application.

Frequently Asked Questions (FAQ)

Q: Can BD90620EFJ-CE2 or BD90620UEFJ-CE2 directly replace BD9006F-E2 on existing PCBs?

A: Package compatibility requires verification. The BD9006F-E2 uses an 8-SOIC package with 0.173" width, while both substitute parts use 8-SOIC with 0.154" width and exposed pad. Pinout compatibility must be confirmed against the specific application schematic. PCB layout modifications may be necessary to accommodate the exposed pad thermal feature.

Q: What is the primary advantage of the substitute parts over the BD9006F-E2?

A: Both BD90620EFJ-CE2 and BD90620UEFJ-CE2 provide increased output current capacity (2.5A versus 2A), extended operating temperature range (-40°C to 125°C versus -40°C to 105°C), and active product status. BD90620EFJ-CE2 includes AEC-Q100 automotive qualification. These enhancements support higher power applications and improved thermal performance.

Q: Why is the BD9006F-E2 marked "Not For New Designs"?

A: This designation indicates ROHM has transitioned this product to end-of-life status and recommends using newer alternatives for new development. The BD90620 series represents the current generation replacement with improved specifications and ongoing manufacturing support.

Q: Are there differences in switching frequency between the substitute parts?

A: BD90620EFJ-CE2 operates at 50kHz to 500kHz, matching the original BD9006F-E2. BD90620UEFJ-CE2 extends the upper frequency limit to 600kHz, enabling higher frequency operation for applications requiring reduced component size or improved transient response.

Q: What is the significance of the exposed pad in the substitute parts?

A: The exposed pad provides direct thermal connection to the PCB, improving heat dissipation compared to the original package without exposed pad. This enhancement supports the increased 2.5A current rating and extended operating temperature range.

Q: Does input voltage range affect substitution compatibility?

A: Yes. The BD9006F-E2 requires minimum 7V input, while BD90620EFJ-CE2 accepts 5V minimum and BD90620UEFJ-CE2 accepts 4.6V minimum. Applications operating below 7V input require BD90620UEFJ-CE2. Applications with 7V or higher input can use either substitute part.
