Substitute Part Grouping Explanation

Substitution for the IRS2541C is determined by the following critical parameters:

• Functional Category: Power Management (PMIC) / LED Driver IC
• Topology: Step-Down (Buck) converter
• Dimming Control: PWM dimming capability
• Output Configuration: Single output
• Regulatory Compliance: REACH Unaffected, EAR99 classification
• Tariff Classification: HTSUS 8542.39.0001

The primary substitute identified is the IRS25411STRPBF, which shares the same base product number (IRS2541 series), manufacturer, and functional classification. This part maintains compatibility through equivalent LED driver functionality and PWM dimming control, while offering active product status and improved availability.

• Product Status: The IRS25411STRPBF holds active product status with substantial inventory availability (30,200 pcs), providing long-term supply security compared to the obsolete IRS2541C.
• Compliance Certification: The IRS25411STRPBF is ROHS3 compliant, meeting current environmental and hazardous substance restrictions.

Frequently Asked Questions (FAQ)

Q: Why is the IRS2541C considered obsolete? A: The IRS2541C is designated as obsolete by Infineon Technologies, indicating it has been discontinued and is no longer in active production. Existing inventory is limited, making substitution necessary for new designs and ongoing production support.

Q: What makes IRS25411STRPBF a valid substitute for IRS2541C? A: Both parts share the same base product number (IRS2541 series), are manufactured by Infineon Technologies, and provide equivalent LED driver functionality with PWM dimming control. Both operate as step-down (buck) converters with single output configuration and identical regulatory classifications.

Q: Are there package differences between IRS2541C and IRS25411STRPBF? A: The IRS2541C packaging details are not specified in the available data. The IRS25411STRPBF is supplied in 8-SOIC (0.154", 3.90mm Width) package format with Tape & Reel (TR) packaging. PCB layout and footprint compatibility must be verified during design integration.

Q: What is the difference in Moisture Sensitivity Level (MSL) between these parts? A: The IRS2541C carries MSL 1 (Unlimited), while the IRS25411STRPBF carries MSL 2 (1 Year). MSL 2 requires controlled storage conditions and handling procedures within a one-year window from the date of manufacture. This difference affects storage, handling, and reflow processing requirements.

Q: Are both parts ROHS compliant? A: The IRS25411STRPBF is explicitly ROHS3 compliant. RoHS status for the IRS2541C is not specified in the available data. Verification of RoHS compliance for the IRS2541C should be obtained from Infineon Technologies if required for your application.

Q: What is the operating frequency of these parts? A: The IRS25411STRPBF operates at 500kHz. Operating frequency for the IRS2541C is not specified in the available data.
