Engineering Selection Recommendations

LP38690SD-2.5/NOPB (Texas Instruments)

This part is the primary substitute for the obsolete LP38692SD-2.5. It maintains identical electrical and mechanical specifications while offering active product status. The LP38690SD-2.5/NOPB is ROHS3 compliant, making it suitable for applications requiring environmental compliance. Packaging is supplied in Tape & Reel (TR) format, which is standard for production environments. Current inventory availability is 3,925 units.

LP38692SD-2.5/NOPB (National Semiconductor)

This part provides an alternative substitute with identical electrical specifications and packaging. It is supplied in bulk packaging and maintains active product status. Current inventory availability is 1,391 units. This option is suitable when bulk packaging is preferred or when supply from the primary substitute is constrained.

Both substitutes are electrically and mechanically interchangeable with the original LP38692SD-2.5 and require no circuit modifications for implementation.

Frequently Asked Questions (FAQ)

Q: Can LP38690SD-2.5/NOPB be used as a direct replacement for LP38692SD-2.5?

A: Yes. The LP38690SD-2.5/NOPB is electrically and mechanically identical to the LP38692SD-2.5. All critical parameters including output voltage, current rating, dropout voltage, package type, and operating temperature range are matched. No circuit modifications are required.

Q: What is the difference between LP38690SD-2.5/NOPB and LP38692SD-2.5/NOPB?

A: Both parts are electrically equivalent with identical specifications. The primary differences are manufacturer source (Texas Instruments vs. National Semiconductor) and packaging format (Tape & Reel vs. Bulk). Selection between these two depends on packaging requirements and supply availability.

Q: Why is the original LP38692SD-2.5 listed as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand and product lifecycle decisions. The LP38690SD-2.5/NOPB serves as the active replacement in the product line.

Q: Are there any compliance differences between the substitutes?

A: The LP38690SD-2.5/NOPB is ROHS3 compliant, while the original LP38692SD-2.5 is RoHS non-compliant. For applications requiring environmental compliance certification, the LP38690SD-2.5/NOPB is the appropriate selection.

Q: Will the 6-WSON (3x3) package fit the same PCB footprint?

A: Yes. All three parts use the 6-WDFN Exposed Pad package with identical physical dimensions and pin configuration. PCB layout and footprint remain unchanged.

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

A: The "/NOPB" suffix indicates the part is supplied without plumbum (lead-free). This designation confirms RoHS compliance for the specific part variant.
