Substitute Part Grouping Explanation

Substitute parts for the LP38692MPX-5.0 are identified based on electrical and mechanical parameter equivalence. The critical parameters determining substitutability are:

• Fixed output voltage of 5V
• Output current rating of 1A
• Maximum input voltage of 10V
• Dropout voltage of 0.8V @ 1A
• Quiescent current of 55 µA
• PSRR of 55dB (120Hz)
• Operating temperature range of -40°C ~ 125°C
• SOT-223-5 package configuration
• Surface mount mounting type
• Over temperature protection

All identified substitutes maintain these electrical specifications and package requirements, ensuring functional compatibility in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

For designs currently using the LP38692MPX-5.0, the following selection criteria apply based on product status and compliance requirements:

LP38692MP-5.0/NOPB is the primary recommended substitute. This part maintains full electrical equivalence with the main part while offering active product status and ROHS3 compliance. The /NOPB designation indicates lead-free construction, aligning with modern manufacturing standards.

LP38692MP-5.0 serves as an alternative with identical electrical specifications and ROHS3 compliance. This part carries Last Time Buy status, indicating limited future availability.

LP38692MPX-5.0/NOPB provides direct manufacturer equivalence from National Semiconductor with active product status. This option maintains compatibility while offering ongoing supply availability.

Selection between these substitutes should prioritize long-term supply chain stability and compliance requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can LP38692MP-5.0/NOPB directly replace LP38692MPX-5.0 in existing designs?

A: Yes. Both parts maintain identical electrical parameters including 5V fixed output, 1A current rating, 0.8V dropout voltage, and SOT-223-5 package configuration. Pin-to-pin compatibility is assured.

Q: What is the difference between LP38692MPX-5.0 and LP38692MP-5.0?

A: The primary difference is product status. LP38692MPX-5.0 is obsolete, while LP38692MP-5.0 is Last Time Buy. Electrically, both deliver identical performance specifications.

Q: Does the /NOPB designation affect compatibility?

A: No. The /NOPB designation indicates lead-free (no lead/no plumbum) construction and RoHS compliance. Electrical and mechanical compatibility remains unchanged.

Q: Which substitute offers the best long-term availability?

A: LP38692MP-5.0/NOPB carries active product status from Texas Instruments, providing the most reliable long-term supply chain position.

Q: Are there package differences between the substitute parts?

A: LP38692MPX-5.0/NOPB uses SOT-223 packaging, while LP38692MPX-5.0, LP38692MP-5.0, and LP38692MP-5.0/NOPB use SOT-223-5. Both package types are functionally equivalent for this application.

Q: What compliance considerations apply when selecting a substitute?

A: The original LP38692MPX-5.0 is RoHS non-compliant. Substitutes LP38692MP-5.0 and LP38692MP-5.0/NOPB are ROHS3 compliant, meeting current environmental and regulatory requirements.
