Engineering Selection Recommendations

LP38692MP-5.0/NOPB is the primary substitute for the LP38692MP-5.0. Both parts are manufactured by Texas Instruments and share identical electrical specifications and package configuration. The /NOPB designation indicates lead-free plating compliance. This part carries Active product status, ensuring continued availability and support. It maintains ROHS3 compliance and is available in Cut Tape and Digi-Reel packaging formats.

LP38692MPX-5.0/NOPB is a secondary equivalent manufactured by National Semiconductor. All critical electrical parameters match the primary part. This part is also in Active status. The primary difference is packaging format (Bulk instead of Cut Tape/Digi-Reel) and unspecified RoHS status. This part is suitable for applications where packaging format flexibility is acceptable.

For new designs or long-term production requirements, LP38692MP-5.0/NOPB is the recommended choice due to confirmed ROHS3 compliance and standard packaging availability.

Frequently Asked Questions (FAQ)

Q: Can LP38692MP-5.0/NOPB be used as a direct replacement for LP38692MP-5.0?

A: Yes. Both parts are Texas Instruments products with identical electrical specifications, output voltage, current rating, dropout voltage, quiescent current, PSRR, operating temperature range, and package configuration. The /NOPB designation indicates lead-free plating, which is a manufacturing process variant, not a functional difference.

Q: What does the /NOPB suffix mean?

A: /NOPB indicates "No Plumbum" (no lead), signifying lead-free plating compliance. This is a manufacturing specification that does not affect electrical performance or compatibility.

Q: Are there package differences between the substitute parts?

A: LP38692MP-5.0 and LP38692MP-5.0/NOPB are both supplied in SOT-223-5 packages with Cut Tape or Digi-Reel packaging options. LP38692MPX-5.0/NOPB uses Bulk packaging format. The SOT-223 package designation for the National Semiconductor part indicates the same physical footprint. All three parts are surface mount components suitable for the same PCB layout.

Q: Why is the main part number in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this specific part number variant. Equivalent alternatives with Active status are available to ensure design continuity and supply chain reliability.

Q: Can I mix different substitute parts in the same production run?

A: All three parts meet identical electrical specifications and package requirements. However, verify with your procurement and quality assurance processes regarding part number consistency for traceability and documentation purposes.

Q: What compliance certifications apply to these parts?

A: LP38692MP-5.0 and LP38692MP-5.0/NOPB are ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity). Both carry REACH Unaffected status and EAR99 export classification. RoHS status for LP38692MPX-5.0/NOPB is not specified in available documentation.
