• Reference Type: Shunt
• Output Voltage: 5V fixed
• Output Current: 15 mA
• Tolerance: ±0.5%
• Noise Performance: 80µVrms (10Hz to 10kHz)
• Cathode Current: 115 µA
• Operating Temperature Range: -40°C ~ 85°C
• Package: SOT-23-5 (SC-74A, SOT-753)

All identified substitutes maintain identical electrical specifications and mechanical compatibility, ensuring direct functional replacement without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

For new designs and ongoing procurement, LM3411AM5-5.0/NOPB is the primary substitute. This part maintains full electrical and mechanical compatibility while offering active product status and ROHS3 compliance, eliminating obsolescence risk and regulatory concerns associated with the original LM3411AM5-5.0.

LM3411AM5X-5.0/NOPB serves as a secondary option, providing equivalent functionality with ROHS3 compliance. However, its Last Time Buy status indicates limited future availability, making it suitable only for applications with defined production end dates or where Tape & Reel packaging is specifically required.

Both substitutes are electrically and mechanically interchangeable with the original part across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can LM3411AM5-5.0/NOPB be used as a direct replacement for LM3411AM5-5.0?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including output voltage, current rating, tolerance, noise performance, and package configuration. The primary difference is product status and compliance certification.

Q: What is the difference between LM3411AM5-5.0/NOPB and LM3411AM5X-5.0/NOPB?

A: Both parts are electrically equivalent. The primary differences are manufacturer packaging format (Bulk vs. Tape & Reel) and product lifecycle status (Active vs. Last Time Buy). Electrical performance and mechanical compatibility are identical.

Q: Why is the original LM3411AM5-5.0 listed as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. Active equivalents are available with identical specifications and improved compliance status.

Q: Are there any package or pinout differences between these parts?

A: No. All parts use the SOT-23-5 package (SC-74A, SOT-753) with identical pinout and mechanical dimensions, enabling direct PCB-level substitution.

Q: What compliance advantages do the substitute parts offer?

A: LM3411AM5-5.0/NOPB and LM3411AM5X-5.0/NOPB are both ROHS3 compliant, whereas the original part is RoHS non-compliant. This eliminates regulatory restrictions in applications subject to RoHS directives.

Q: Which substitute should be selected for new production?

A: LM3411AM5-5.0/NOPB is recommended for new designs due to its active product status and bulk packaging availability, ensuring long-term supply continuity.
