Substitute Part Grouping Explanation

Substitution of the LM5025ASDX/NOPB is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part LM5025ASD/NOPB maintains identical specifications across the following key criteria:

• Voltage supply range: 8V ~ 15V
• Switching frequency range: 200kHz ~ 580kHz
• Maximum duty cycle: 80%
• Operating temperature range: -40°C ~ 125°C
• Package configuration: 16-WFDFN Exposed Pad (16-WSON 5x5)
• Topology: Forward Converter
• Output configuration: Positive, Isolation Capable
• Number of outputs: 2
• Control features: Dead Time Control, Frequency Control, Ramp, Soft Start
• RoHS3 compliance and MSL Level 1 rating

The substitute part differs only in product status classification and inventory availability, with no variation in functional or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The LM5025ASD/NOPB serves as a direct parametric equivalent to the LM5025ASDX/NOPB for all electrical and mechanical applications. Both parts maintain identical functional specifications, package geometry, and compliance certifications (ROHS3, MSL Level 1, REACH Unaffected, EAR99 classification).

Selection between these parts should be based on product lifecycle status and supply availability. The LM5025ASDX/NOPB maintains active production status with higher inventory levels (5690 units), making it suitable for new designs and long-term supply requirements. The LM5025ASD/NOPB carries Last Time Buy status with lower inventory (2243 units), appropriate for existing designs requiring component replenishment within the remaining product lifecycle window.

Both parts are suitable for forward converter applications requiring positive, isolation-capable outputs with integrated dead time and frequency control across the 8V to 15V supply range and -40°C to 125°C operating temperature envelope.

Frequently Asked Questions (FAQ)

Q: Are LM5025ASDX/NOPB and LM5025ASD/NOPB electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including supply voltage range (8V ~ 15V), switching frequency range (200kHz ~ 580kHz), duty cycle maximum (80%), operating temperature range (-40°C ~ 125°C), and all control features (dead time control, frequency control, ramp, soft start).

Q: Do these parts use the same package?

A: Yes. Both parts use the 16-WFDFN Exposed Pad package (16-WSON 5x5), ensuring identical PCB footprint and mounting requirements.

Q: What is the difference between these two part numbers?

A: The primary difference is product status. LM5025ASDX/NOPB is in active production, while LM5025ASD/NOPB is designated Last Time Buy. Inventory levels also differ, with LM5025ASDX/NOPB having 5690 units available versus 2243 units for LM5025ASD/NOPB.

Q: Can I use LM5025ASD/NOPB in a new design?

A: LM5025ASD/NOPB is available for use; however, its Last Time Buy status indicates limited future availability. For new designs with extended production lifecycles, LM5025ASDX/NOPB is recommended due to active production status.

Q: Are compliance certifications identical?

A: Yes. Both parts carry identical certifications: ROHS3 Compliant, Moisture Sensitivity Level 1 (Unlimited), REACH Unaffected status, and EAR99 ECCN classification.

Q: What applications are these parts suitable for?

A: Both parts function as forward converter regulator controllers for positive, isolation-capable output step-up/step-down DC-DC conversion applications requiring integrated transistor driver output and advanced control features across 8V to 15V supply inputs.
