Engineering Selection Recommendations

Primary Substitute: IRS25411STRPBF

The IRS25411STRPBF is the manufacturer-recommended equivalent for the obsolete IRS2541CD. Selection of this substitute is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• Identical manufacturer (Infineon Technologies) and regulatory classification (REACH Unaffected, EAR99)
• Matching HTSUS code (8542.39.0001) confirming tariff classification alignment
• Shared LED driver control and PWM dimming functionality
• ROHS3 compliance providing environmental regulatory advantage over the main part
• Significantly higher inventory availability (30200 Pcs vs. 1139 Pcs)

The MSL rating difference (MSL 1 vs. MSL 2) reflects standard industry practice for active versus obsolete products and does not impact functional substitution.

Frequently Asked Questions (FAQ)

Q: Why is the IRS2541CD obsolete? A: The IRS2541CD has reached end-of-life status. The manufacturer-recommended active substitute is IRS25411STRPBF, which provides equivalent LED driver control functionality with improved supply chain availability.

Q: What are the key compatibility criteria for substitution? A: Substitution is based on matching LED driver control application requirements, PWM dimming capability, buck topology, single output configuration, and regulatory compliance (REACH, ECCN, HTSUS). Both parts are Infineon Technologies products within the Power Management (PMIC) category.

Q: Does the package change affect circuit board design? A: The IRS25411STRPBF uses an 8-SOIC (0.154", 3.90mm Width) surface mount package. Verify that your PCB layout accommodates this package specification. The main part's package information was not provided for direct comparison.

Q: What is the difference in Moisture Sensitivity Level (MSL)? A: The IRS2541CD has MSL 1 (Unlimited shelf life), while IRS25411STRPBF has MSL 2 (1 Year shelf life). This reflects standard industry practice and does not affect functional performance or substitution validity.

Q: Are there regulatory or compliance concerns with substitution? A: Both parts share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8542.39.0001). The IRS25411STRPBF adds ROHS3 compliance, providing additional environmental regulatory alignment.

Q: What is the operating frequency of the substitute? A: The IRS25411STRPBF operates at 500kHz switching frequency. Confirm this frequency is compatible with your application's power supply design and filtering requirements.

Q: What is the supply voltage range for the substitute? A: The IRS25411STRPBF operates with a supply voltage range of 8V to 16.6V. Verify your system's input voltage falls within this specification.
