BD00HC5MEFJ-LBH2 Equivalent & Substitute Parts

Part Overview

The BD00HC5MEFJ-LBH2 is a linear voltage regulator IC from Rohm Semiconductor designed for positive adjustable output applications. This Surface Mount device delivers 1.5A output current with adjustable voltage regulation from 1.5V to 7V, operating across the industrial temperature range of -40°C to 105°C. The component is actively produced and widely used in power management applications requiring compact, reliable voltage regulation with integrated protection features.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across different manufacturing variants or series designations.

Substitute Part Grouping Explanation

Substitution eligibility for the BD00HC5MEFJ-LBH2 is determined by strict equivalence across the following critical parameters:

• Output voltage range: 1.5V to 7V adjustable
• Output current capacity: 1.5A
• Maximum input voltage: 8V
• Voltage dropout: 1.2V @ 1.5A
• Package type: 8-HTSOP-J (8-SOIC with exposed pad)
• Control and protection features: Enable function, Over Current, Over Temperature, Soft Start
• Operating temperature range: -40°C to 105°C
• Mounting configuration: Surface Mount
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The BD00HC5MEFJ-ME2 meets all these criteria and is classified as a parametric equivalent. Differences in series designation (automotive qualification, AEC-Q100 certification) and quiescent current specification do not affect functional substitution when electrical and mechanical parameters remain identical.

Engineering Selection Recommendations

Both the BD00HC5MEFJ-LBH2 and BD00HC5MEFJ-ME2 are active products from Rohm Semiconductor with identical electrical specifications and mechanical compatibility. Selection between these parts should be based on:

• Supply chain availability and lead time requirements
• Series-specific requirements: The BD00HC5MEFJ-ME2 carries AEC-Q100 automotive qualification, making it suitable for automotive and high-reliability applications
• Inventory status: BD00HC5MEFJ-ME2 has higher stock availability (6900 Pcs vs. 999 Pcs)
• Regulatory compliance: Both parts meet ROHS3 and REACH requirements

Direct substitution is permissible when electrical performance, thermal management, and package footprint requirements are met. No design modifications or re-qualification are required when switching between these equivalent parts.

Frequently Asked Questions (FAQ)

Q: Can BD00HC5MEFJ-ME2 be used as a direct replacement for BD00HC5MEFJ-LBH2?

A: Yes. Both parts share identical electrical specifications, output voltage range (1.5V to 7V), output current (1.5A), package type (8-HTSOP-J), and protection features. Direct substitution is permissible without circuit modification.

Q: What is the difference between the LBH2 and ME2 variants?

A: The primary difference is series designation. The ME2 variant includes AEC-Q100 automotive qualification, indicating enhanced reliability testing and suitability for automotive applications. Electrical and mechanical parameters remain identical.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 8-SOIC (0.154", 3.90mm Width) Exposed Pad package with 8-HTSOP-J supplier designation. PCB footprints and thermal pad dimensions are equivalent.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid when the following parameters match: output voltage range (1.5V to 7V), output current (1.5A), maximum input voltage (8V), voltage dropout (1.2V @ 1.5A), package type (8-HTSOP-J), control features (Enable), protection features (Over Current, Over Temperature, Soft Start), and operating temperature range (-40°C to 105°C).

Q: Is re-qualification required when switching between these parts?

A: No. Both parts are from the same manufacturer, share identical electrical specifications, and meet the same regulatory standards (ROHS3, REACH). No design changes or re-testing are necessary for direct substitution.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For automotive or high-reliability applications, BD00HC5MEFJ-ME2 is recommended due to AEC-Q100 qualification. For general industrial applications, either part is suitable. Verify supply chain availability and lead times for your procurement timeline.
