Parameter Comparison

Engineering Selection Recommendations

The LM2936HVBMA-3.3/NOPB serves as the direct substitute for the LM2936HVBMA-3.3. Both parts are manufactured by Texas Instruments with identical electrical and mechanical specifications. The substitute part carries Active product status, ensuring continued availability and supply chain support.

Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage and handling.

Selection between these parts should prioritize the Active status part (LM2936HVBMA-3.3/NOPB) for new designs and ongoing production to ensure long-term component availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Are LM2936HVBMA-3.3 and LM2936HVBMA-3.3/NOPB electrically interchangeable?

A: Yes. Both parts deliver identical electrical performance with 3.3V fixed output, 50mA current capability, 60V maximum input voltage, and 0.4V dropout voltage at rated current. All protection and control features are identical.

Q: What is the difference between these part numbers?

A: The primary difference is product status. LM2936HVBMA-3.3 is designated Last Time Buy, while LM2936HVBMA-3.3/NOPB carries Active status. The "/NOPB" suffix indicates lead-free plating. Packaging format differs (standard vs. Tube), but functional specifications remain identical.

Q: Can I use LM2936HVBMA-3.3/NOPB as a direct replacement in existing designs?

A: Yes. The 8-SOIC package dimensions are identical (0.154", 3.90mm Width), and all electrical parameters match exactly. No circuit modifications or PCB layout changes are required.

Q: Why should I transition to the Active status part?

A: The LM2936HVBMA-3.3/NOPB maintains Active product status, ensuring continued manufacturer support, availability, and compliance with current regulatory standards. The Last Time Buy designation on the original part indicates limited future availability.

Q: Are there any compliance or certification differences?

A: Both parts maintain ROHS3 compliance and REACH unaffected status. MSL rating is identical at 1 (Unlimited). No compliance or certification differences exist between the two parts.
