LM5026MT Equivalent & Substitute Parts

Part Overview

The LM5026MT is a Forward Converter Regulator IC manufactured by Texas Instruments, designed for positive, isolation-capable output step-up/step-down DC-DC control applications. This device functions as a transistor driver controller with integrated dead time control, frequency control, reset, and soft start features. The LM5026MT is currently in Last Time Buy status, indicating end-of-life production. Identifying equivalent substitute parts is necessary to ensure design continuity and maintain supply chain reliability for applications requiring this controller topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM5026MT is determined by strict equivalence across the following critical parameters:

• Package / Case: 16-TSSOP form factor with identical 0.173" (4.40mm) width
• Topology: Forward Converter architecture
• Output Type: Transistor Driver configuration
• Output Configuration: Positive, Isolation Capable
• Number of Outputs: 2 outputs
• Voltage - Supply Range: 8V ~ 15V
• Frequency - Switching Range: 200kHz ~ 590kHz
• Duty Cycle (Max): 70%, 80%
• Operating Temperature Range: -40°C ~ 125°C (TJ)
• Control Features: Dead Time Control, Frequency Control, Reset, Soft Start
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The LM5026MTX/NOPB qualifies as a direct substitute based on complete parameter alignment across all specified electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The LM5026MTX/NOPB is the direct substitute for the LM5026MT. The primary distinction between these parts is product status: the LM5026MT is in Last Time Buy phase, while the LM5026MTX/NOPB maintains Active status with ongoing production and availability. Both parts are ROHS3 compliant and carry identical electrical and mechanical specifications. Selection of the LM5026MTX/NOPB is appropriate for new designs and ongoing production requirements where supply continuity is a consideration. The packaging designation (Cut Tape and Digi-Reel) for the LM5026MTX/NOPB indicates standard distribution formats suitable for manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can the LM5026MTX/NOPB be used as a direct replacement for the LM5026MT?

A: Yes. Both parts share identical electrical specifications, package form factor, and control feature sets. The LM5026MTX/NOPB is the active production equivalent.

Q: What is the difference between LM5026MT and LM5026MTX/NOPB?

A: The primary difference is product lifecycle status. The LM5026MT is Last Time Buy, while LM5026MTX/NOPB is Active. Electrical and mechanical parameters are identical. The suffix designations indicate packaging and lead finish specifications.

Q: Are both parts available in the same package?
