Substitute Part Grouping Explanation

Substitution of the LM5032MTCX is determined by strict equivalence across the following critical parameters:

• Package / Case: 16-TSSOP form factor with identical 0.173" width and 4.40mm dimensions
• Output Type and Topology: Transistor driver with forward converter topology
• Output Configuration: Positive output with dual phases
• Voltage Supply Range: 13V ~ 100V operation
• Switching Frequency: 200kHz and 600kHz capability
• Duty Cycle Maximum: 76%
• Operating Temperature Range: -40°C ~ 125°C (TJ)
• Control Features: Frequency control and soft start functionality

The LM5032MTCX/NOPB is a parametric equivalent that maintains all electrical and mechanical specifications while differing in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The LM5032MTCX is classified as obsolete, necessitating transition to available alternatives. The LM5032MTCX/NOPB provides complete parametric equivalence with identical electrical and mechanical specifications, ensuring direct functional compatibility in existing designs.

The primary distinction between these parts is regulatory compliance. The LM5032MTCX/NOPB carries ROHS3 compliance certification, whereas the original LM5032MTCX is RoHS non-compliant. Both parts maintain identical MSL ratings and REACH status. The LM5032MTCX/NOPB is designated as Last Time Buy, indicating limited availability with defined end-of-life parameters.

For new designs or production continuity, the LM5032MTCX/NOPB is the appropriate selection, offering regulatory alignment with current environmental standards while maintaining full electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the LM5032MTCX/NOPB directly replace the LM5032MTCX in existing designs?

A: Yes. The LM5032MTCX/NOPB is a parametric equivalent with identical electrical specifications, output configuration, package form factor, and control features. No circuit modifications are required for direct substitution.

Q: What is the significance of the "/NOPB" suffix?

A: The "/NOPB" designation indicates the part is supplied without lead (Pb), reflecting RoHS3 compliance. This affects material composition and environmental certifications but does not alter electrical performance or functional operation.

Q: Are there differences in packaging or handling between these parts?

A: Both parts use the 16-TSSOP package with identical dimensions. Moisture sensitivity levels are equivalent at MSL 1 (Unlimited). Packaging format may differ (the LM5032MTCX/NOPB is available in Cut Tape and Digi-Reel formats), but this does not affect component functionality.

Q: Why is the LM5032MTCX classified as obsolete?

A: Product obsolescence reflects Texas Instruments' end-of-life determination for this device. The LM5032MTCX/NOPB represents the current equivalent offering with extended availability through the Last Time Buy phase.

Q: Are the switching frequency and duty cycle specifications identical?

A: Yes. Both parts support 200kHz and 600kHz switching frequencies with a maximum duty cycle of 76%. Operating temperature ranges are identical at -40°C to 125°C (TJ).

Q: What compliance certifications apply to each part?

A: The LM5032MTCX is RoHS non-compliant. The LM5032MTCX/NOPB is ROHS3 compliant. Both maintain REACH Unaffected status and identical ECCN and HTSUS classifications.
