Substitute Part Grouping Explanation

Substitute parts for the LP38692MPX-1.8/NOPB are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

• Fixed output voltage of 1.8V
• Output current rating of 1A
• Maximum input voltage of 10V
• Dropout voltage of 1.6V @ 1A
• Quiescent current of 55 µA
• PSRR of 55dB (120Hz)
• Operating temperature range of -40°C to 125°C
• Surface Mount packaging with SOT-223 package family compatibility
• Active product status
• Over Temperature protection feature

The LP38692MP-1.8/NOPB meets all these criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the LP38692MPX-1.8/NOPB and LP38692MP-1.8/NOPB are Active status products with identical electrical specifications. Selection between these parts should be based on:

• Packaging format requirements: The main part is supplied in Tape & Reel format, while the substitute is supplied in Bulk format. Choose based on assembly process and volume requirements.
• Compliance certifications: Both parts are ROHS3 Compliant and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8542.39.0001).
• Inventory availability: The substitute part currently has 1558 units in stock compared to 1292 units for the main part.
• Manufacturer preference: Texas Instruments (main) versus National Semiconductor (substitute) may influence selection based on supply chain strategy or existing vendor relationships.

Frequently Asked Questions (FAQ)

Q: Can LP38692MP-1.8/NOPB be used as a direct replacement for LP38692MPX-1.8/NOPB?

A: Yes. Both parts share identical electrical specifications including output voltage, current rating, dropout voltage, quiescent current, and PSRR. The primary difference is packaging format (Tape & Reel versus Bulk) and manufacturer. Verify that your assembly process accommodates the Bulk packaging format of the substitute part.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by: fixed 1.8V output voltage, 1A output current, 10V maximum input voltage, 1.6V dropout voltage at 1A, 55 µA quiescent current, 55dB PSRR at 120Hz, -40°C to 125°C operating temperature range, and SOT-223 package family compatibility with Over Temperature protection.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and carry identical ECCN and HTSUS classifications. MSL ratings are equivalent (1 - Unlimited for the main part; not specified for the substitute but compatible with standard handling).

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel and Bulk packaging formats contain identical die and internal construction. The difference is only in the physical delivery and handling format. Electrical performance remains identical.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes, provided the PCB footprint accommodates the SOT-223 package family. Both parts use the same package type (SOT-223-5 and SOT-223 respectively) with compatible pinouts for Surface Mount assembly.
