Key Parameters

Substitute Part Grouping Explanation

The BD9411F-E2 is identified as the manufacturer-recommended substitute. Substitution eligibility is determined by the following criteria:

• Functional equivalence within the power management IC category
• Compatibility with the same application domain (LED driver control and PWM dimming)
• Matching or superior electrical specifications (supply voltage range, output configuration, frequency)
• Compatible packaging and mounting technology (Surface Mount)
• Compliance with applicable regulatory standards (RoHS, REACH)

The BD9411F-E2 meets all substitution criteria as the direct manufacturer-recommended alternative from Rohm Semiconductor.

Parameter Comparison

Engineering Selection Recommendations

The BD9411F-E2 is the primary substitute for the BD9411F. This recommendation is based on:

• Direct manufacturer designation as the recommended equivalent
• Active product status ensuring ongoing availability and supply chain stability
• Full compliance with RoHS3 and REACH regulatory requirements
• Unlimited moisture sensitivity level (MSL 1) suitable for standard storage and handling conditions
• Established inventory levels (55,100 pcs) supporting production requirements

Selection of the BD9411F-E2 eliminates supply risk associated with the Last Time Buy status of the original BD9411F while maintaining functional compatibility within the power management IC category.

Frequently Asked Questions (FAQ)

Q: Why is the BD9411F being phased out? A: The BD9411F carries Last Time Buy status, indicating the manufacturer has discontinued active production. The BD9411F-E2 represents the current active equivalent.

Q: Is the BD9411F-E2 a direct pin-for-pin replacement? A: Both parts utilize the 18-SOIC package format with identical physical dimensions (0.213" width, 5.40mm). Functional compatibility is established through manufacturer designation as the recommended substitute.

Q: What are the key electrical differences between BD9411F and BD9411F-E2? A: The BD9411F-E2 is specified as a DC DC Controller with Step-Up (Boost) topology, single output, 9V to 35V supply range, 150kHz frequency, and Analog/PWM dimming capability. The original BD9411F specifications are not fully detailed in available documentation.

Q: Are there regulatory compliance concerns with substitution? A: No. The BD9411F-E2 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components in most jurisdictions.

Q: What is the moisture sensitivity level (MSL) of the BD9411F-E2? A: The BD9411F-E2 has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling under standard conditions.

Q: Can the BD9411F-E2 be used in existing designs without modification? A: Package compatibility (18-SOIC) and functional equivalence support direct substitution. Design validation should confirm electrical parameter alignment with specific application requirements.
