Frequently Asked Questions (FAQ)

Q: Can DFLS240L-7 be used as a direct replacement for SDM2L40P1-7 in existing designs?

A: Yes. The DFLS240L-7 is electrically and mechanically equivalent to the SDM2L40P1-7 across all specified parameters. No circuit modifications or PCB layout changes are required for substitution.

Q: What are the key differences between SDM2L40P1-7 and DFLS240L-7?

A: The primary difference is product status: SDM2L40P1-7 is obsolete while DFLS240L-7 is active. The DFLS240L-7 features a capacitance specification of 90 pF @ 10 V, 1 MHz compared to 63 pF @ 10 V, 1 MHz for the SDM2L40P1-7. Both parts maintain identical voltage, current, and speed ratings. The DFLS240L-7 includes operating temperature range specification (-55°C ~ 125°C) not provided for the SDM2L40P1-7.

Q: Are there packaging differences between these parts?

A: Both parts use the PowerDI™ 123 surface mount package. The DFLS240L-7 is available in Cut Tape (CT) and Digi-Reel® packaging, while the SDM2L40P1-7 packaging format is not specified in the provided data.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SDM2L40P1-7 and DFLS240L-7 are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity classification. Both are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: What is the inventory status for each part?

A: The SDM2L40P1-7 has 1,007 pcs in stock (obsolete status). The DFLS240L-7 has 95,100 pcs in stock (active status), providing superior supply availability for production requirements.

Q: Are there any electrical performance differences that affect circuit operation?

A: No. Both parts maintain identical voltage ratings (40 V), current ratings (2 A), forward voltage (500 mV @ 2 A), reverse leakage (100 µA @ 40 V), and recovery speed (≤ 500 ns). Circuit performance remains unchanged with substitution.
