LP38693MPX-5.0/NOPB Equivalent & Substitute Parts

Part Overview

The LP38693MPX-5.0/NOPB is a linear voltage regulator IC manufactured by Texas Instruments, classified as a Power Management (PMIC) component. This device delivers a fixed positive 5V output at 500mA maximum current in a surface-mount SOT-223-5 package. The part is currently in active production status with 1625 units available in new original inventory. Substitute parts are identified when packaging format differs while maintaining identical electrical specifications and performance characteristics.

Substitute Part Grouping Explanation

The LP38693MPX-5.0/NOPB has one identified substitute part: LP38693MP-5.0/NOPB. Both parts share the same base product number (LP38693) and are manufactured by Texas Instruments. The substitution is valid based on the following criteria:

• Identical output voltage specification: 5V fixed
• Identical output current rating: 500mA
• Identical input voltage maximum: 10V
• Identical dropout voltage: 0.45V @ 500mA
• Identical package type: SOT-223-5
• Identical operating temperature range: -40°C to 125°C
• Identical control features and protection mechanisms
• Identical compliance certifications (ROHS3, REACH Unaffected)

The only difference between these parts is the packaging format: the main part (MPX) is supplied in Tape & Reel (TR) format, while the substitute (MP) is supplied in Cut Tape (CT) & Digi-Reel® format. This distinction affects procurement and assembly processes but does not alter electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the LP38693MPX-5.0/NOPB and LP38693MP-5.0/NOPB are active production parts from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts should be based on procurement requirements and assembly processes:

• Choose LP38693MPX-5.0/NOPB (Tape & Reel) for high-volume automated assembly operations requiring continuous reel feeding.
• Choose LP38693MP-5.0/NOPB (Cut Tape & Digi-Reel®) for lower-volume production, mixed-component assembly, or when component-level flexibility is required.

Both parts meet ROHS3 compliance and REACH requirements. Inventory availability is significantly higher for the Cut Tape variant (24951 units versus 1625 units), which may influence procurement decisions for time-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can LP38693MP-5.0/NOPB be used as a direct replacement for LP38693MPX-5.0/NOPB in circuit design?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel®). No circuit modifications are required.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous reels suitable for automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® packaging provides components in tape segments or alternative reel formats, offering flexibility for lower-volume or mixed-component assembly processes.

Q: Are there any performance differences between these two part numbers?

A: No. Both parts deliver identical electrical performance: 5V fixed output, 500mA maximum current, 0.45V dropout voltage at rated current, and identical operating temperature range (-40°C to 125°C).

Q: Do both parts meet the same compliance standards?

A: Yes. Both LP38693MPX-5.0/NOPB and LP38693MP-5.0/NOPB are ROHS3 compliant and REACH unaffected.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection depends on manufacturing process requirements. Tape & Reel format is standard for high-volume automated assembly, while Cut Tape & Digi-Reel® format provides flexibility for lower-volume or mixed-component production.
