Substitute Part Grouping Explanation

Substitution for the LP38692SDX-ADJ is determined by matching the following critical parameters:

Output Configuration: Positive
Output Type: Adjustable
Number of Regulators: 1
Voltage - Input (Max): 10V
Voltage - Output (Min/Fixed): 1.25V
Voltage - Output (Max): 9V
Current - Output: 1A
Operating Temperature: -40°C ~ 125°C
Package / Case: 6-WDFN Exposed Pad
Supplier Device Package: 6-WSON (3x3)

All substitute parts listed maintain these electrical and mechanical specifications. Packaging format (Tape & Reel or Cut Tape) and product status variations do not affect functional equivalence.

Engineering Selection Recommendations

The LP38692SDX-ADJ is obsolete and should be replaced with an active equivalent. All listed substitute parts maintain identical electrical specifications and package form factor.

For new designs and procurement:

LP38692SDX-ADJ/NOPB and LP38692SD-ADJ/NOPB are direct substitutes based on the LP38692 base product number. Both are Active status and ROHS3 Compliant. Choose based on packaging requirement: Tape & Reel (TR) for automated assembly or Cut Tape (CT) & Digi-Reel® for manual handling.

LP38690SDX-ADJ/NOPB and LP38690SD-ADJ/NOPB are parametric equivalents based on the LP38690 base product number. Both are Active status and ROHS3 Compliant with identical electrical performance. These parts are functionally interchangeable with the LP38692 variants.

All substitute parts carry ROHS3 Compliance and REACH Unaffected status, meeting modern regulatory requirements. Moisture Sensitivity Level remains 1 (Unlimited) across all variants.

Frequently Asked Questions (FAQ)

Q: Can I use LP38690SDX-ADJ/NOPB as a direct replacement for LP38692SDX-ADJ?

A: Yes. Both parts share identical electrical specifications: 10V maximum input, 1.25V to 9V adjustable output, 1A output current, 55 µA quiescent current, and 6-WSON (3x3) package. The LP38690 and LP38692 base product numbers are parametric equivalents for this application.

Q: What is the difference between LP38692SDX-ADJ/NOPB and LP38692SD-ADJ/NOPB?

A: The primary difference is packaging format. The SDX variant uses Tape & Reel (TR) packaging suitable for automated pick-and-place assembly. The SD variant uses Cut Tape (CT) & Digi-Reel® packaging for manual component handling. Electrical specifications and package form factor are identical.

Q: Why is the original LP38692SDX-ADJ listed as Obsolete?

A: The original part is no longer in active production. Active equivalents with improved compliance status (ROHS3 Compliant) are available as direct replacements.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed are ROHS3 Compliant. The original LP38692SDX-ADJ is RoHS non-compliant. For applications requiring RoHS compliance, use any of the active substitute parts.

Q: Can I mix packaging formats in the same design?

A: Yes. All variants maintain identical electrical performance and physical package dimensions (6-WSON 3x3). Packaging format selection depends on assembly process requirements, not electrical compatibility.

Q: What is the dropout voltage for these regulators?

A: The LP38690 variants specify 1.6V dropout at 1A. The LP38692 variants do not specify dropout voltage in the provided data. For dropout-critical applications, LP38690 variants provide documented performance.
