Engineering Selection Recommendations

LM3535TMX/NOPB (MFR Recommended Substitute): This part is the manufacturer-recommended substitute with active product status. It maintains all electrical and mechanical specifications identical to the obsolete LM3535TMX-2ALS/NOPB. Availability is significantly higher (41,270 units in stock versus 945 units for the main part). This option is suitable for new procurement and design transitions from the obsolete variant.

LM3535TME/NOPB (Parametric Equivalent): This part is a parametric equivalent with active product status from Texas Instruments. All electrical specifications and package configurations match the main part exactly. It is supplied in Tape & Reel packaging and carries ROHS3 compliance and MSL Level 1 certification. This option is appropriate for high-volume production environments requiring reel packaging.

Both substitutes are compliant with ROHS3 and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications as the main part, ensuring regulatory and export compliance continuity.

Frequently Asked Questions (FAQ)

Q: Can LM3535TMX/NOPB be used as a direct replacement for LM3535TMX-2ALS/NOPB? A: Yes. Both parts share identical electrical specifications, output configuration, supply voltage range, output voltage range, current ratings, switching frequency, PWM dimming capability, and 20-DSBGA package. The primary difference is product status (active versus obsolete) and packaging format (bulk versus unspecified).

Q: What is the difference between LM3535TMX/NOPB and LM3535TME/NOPB? A: Both are parametric equivalents with identical electrical and mechanical specifications. The primary difference is packaging: LM3535TMX/NOPB is supplied in bulk, while LM3535TME/NOPB is supplied in Tape & Reel format. Selection depends on procurement and assembly requirements.

Q: Are there any compliance or certification differences between the substitutes? A: LM3535TME/NOPB explicitly carries ROHS3 compliance and MSL Level 1 certification. LM3535TMX/NOPB compliance information is not specified in available data. Both maintain identical ECCN and HTSUS classifications.

Q: Is the 20-DSBGA package compatible with existing PCB designs? A: Yes. All three parts use the identical 20-DSBGA package configuration, ensuring mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Q: Why is the main part listed as obsolete? A: The LM3535TMX-2ALS/NOPB is classified as obsolete by the manufacturer. Active substitutes within the LM3535 family are available to support ongoing design requirements and procurement needs.
