Substitute Part Grouping Explanation

Substitution of the LM5110-1M/NOPB is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side operation
• Number of Drivers: Dual independent channels
• Gate Type: N-Channel MOSFET driving capability
• Voltage Supply Range: 4.6V ~ 14V
• Logic Voltage Thresholds: VIL 0.8V, VIH 2.2V
• Peak Output Current: Source 3A, Sink 5A
• Input Logic: Non-Inverting
• Rise/Fall Time Performance: 14ns rise, 12ns fall (typical)
• Operating Temperature Range: -40°C ~ 125°C
• Package: 8-SOIC form factor with 0.154" (3.90mm) width
• Compliance: ROHS3, REACH Unaffected

The LM5110-1MX/NOPB qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is packaging format: the main part uses Tube packaging, while the substitute uses Cut Tape (CT) & Digi-Reel® packaging.

Parameter Comparison

Engineering Selection Recommendations

The LM5110-1MX/NOPB is the manufacturer-recommended substitute for the LM5110-1M/NOPB. Both parts share identical electrical and thermal specifications, ensuring functional equivalence in gate driver applications. The LM5110-1MX/NOPB maintains Active product status, providing long-term supply availability compared to the Last Time Buy status of the main part. Both devices meet ROHS3 compliance and REACH unaffected requirements, supporting regulatory requirements for industrial and commercial applications. Selection between these parts should be based on packaging requirements: Tube format for the original part versus Cut Tape and Digi-Reel® options for the substitute. Inventory availability and procurement lead times may also influence selection, as the substitute part shows significantly higher stock levels.

Frequently Asked Questions (FAQ)

Q: Can the LM5110-1MX/NOPB be used as a direct replacement for the LM5110-1M/NOPB?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: Tube versus Cut Tape/Digi-Reel®. PCB layout and circuit design require no modification.

Q: What is the significance of the Last Time Buy status on the LM5110-1M/NOPB?

A: Last Time Buy indicates the manufacturer has discontinued production. The LM5110-1MX/NOPB, with Active status, is the recommended path for new designs and ongoing production requirements.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Operating temperature range, supply voltage, output current ratings, and switching characteristics are identical across both part numbers.

Q: Does the packaging format affect circuit performance?

A: No. Tube and Cut Tape/Digi-Reel® packaging formats contain identical die and internal circuitry. Packaging differences affect only handling, storage, and automated assembly processes.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both parts operate across -40°C to 125°C junction temperature range, supporting industrial and automotive thermal environments within this specification.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for industrial electronics applications.
