LP38692SDX-5.0 Equivalent & Substitute Parts

Part Overview

The LP38692SDX-5.0 is a linear voltage regulator IC from Texas Instruments designed for positive fixed 5V output at 1A current capacity in a 6-WSON (3x3) surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. The device provides regulated 5V output with a maximum dropout voltage of 0.8V at 1A and includes over-temperature protection.

Substitute Part Grouping Explanation

Substitution for the LP38692SDX-5.0 is determined by strict equivalence across the following critical parameters:

Output voltage configuration: 5V fixed positive output
Output current rating: 1A
Maximum input voltage: 10V
Dropout voltage specification: 0.8V @ 1A
Quiescent current: 55 µA
PSRR performance: 55dB (120Hz)
Operating temperature range: -40°C to 125°C
Package and pinout: 6-WSON (3x3) with exposed pad
Protection features: Over-temperature protection

All substitute parts listed maintain identical electrical specifications and package compatibility. Differences exist only in product status, RoHS compliance level, and packaging format (cut tape vs. tape & reel).

Engineering Selection Recommendations

For new designs and production applications, LP38692SDX-5.0/NOPB is the primary direct substitute. This part maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance, addressing the obsolescence of the original LP38692SDX-5.0.

LP38692SD-5.0/NOPB provides equivalent functionality with the same active status and compliance profile. This variant differs only in packaging format (tape & reel vs. cut tape), making it suitable for high-volume production environments.

LP38690SDX-5.0/NOPB and LP38690SD-5.0/NOPB are parametric equivalents from the LP38690 base product line. These parts deliver identical electrical performance and package compatibility. Selection between LP38692 and LP38690 variants should be based on inventory availability and supply chain considerations, as all parts meet the same functional requirements.

All substitute parts carry ROHS3 compliance and REACH unaffected status, supporting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can LP38692SD-5.0/NOPB directly replace LP38692SDX-5.0?

A: Yes. Both parts share identical electrical specifications, output voltage, current rating, dropout voltage, and 6-WSON (3x3) package. The primary difference is product status (active vs. obsolete) and RoHS compliance level. The /NOPB designation indicates lead-free, halogen-free construction.

Q: What is the difference between LP38692 and LP38690 variants?

A: Both base product lines deliver identical electrical performance across all critical parameters: 5V fixed output, 1A current capacity, 0.8V dropout voltage, and 55dB PSRR. The distinction lies in the base product number only. All substitute parts listed are functionally interchangeable.

Q: Does packaging format affect electrical performance?

A: No. The difference between SDX and SD designations refers to packaging format (cut tape vs. tape & reel). Electrical specifications, thermal performance, and reliability characteristics remain identical. Selection should be based on procurement and assembly requirements.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed carry ROHS3 compliance. The original LP38692SDX-5.0 is RoHS non-compliant. For applications requiring RoHS compliance, use LP38692SDX-5.0/NOPB, LP38692SD-5.0/NOPB, LP38690SDX-5.0/NOPB, or LP38690SD-5.0/NOPB.

Q: What is the moisture sensitivity level for these parts?

A: All parts in this family carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can I use these parts interchangeably in existing designs?

A: Yes, provided the original design uses the 6-WSON (3x3) package footprint. All substitute parts maintain identical pinout, package dimensions, and electrical specifications. No circuit modifications are required.
