Key Parameters

Substitute Part Grouping Explanation

Substitution of the LP38692MPX-2.5/NOPB is determined by strict equivalence across the following critical parameters:

• Output voltage: 2.5V fixed
• Output current capability: 1A minimum
• Maximum input voltage: 10V
• Dropout voltage: 1.3V @ 1A maximum
• Package type: SOT-223-5 (TO-261-5, TO-261AB)
• Quiescent current: 55 µA
• Operating temperature range: -40°C to 125°C
• Protection: Over temperature protection required
• Compliance: ROHS3 and REACH requirements

The LP38692MP-2.5/NOPB meets all these criteria and is classified as a parametric equivalent. The primary distinction between the main part and its substitute is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

Selection between these parts should be based on availability and procurement requirements. The active status of LP38692MP-2.5/NOPB makes it the preferred choice for new designs and ongoing production.

Frequently Asked Questions (FAQ)

Q: Can LP38692MP-2.5/NOPB be used as a direct replacement for LP38692MPX-2.5/NOPB?

A: Yes. Both parts are electrically and mechanically identical. They share the same output voltage, current rating, dropout voltage, quiescent current, operating temperature range, and SOT-223-5 package configuration. The primary difference is product status and packaging format.

Q: What is the difference between the packaging formats?

A: LP38692MPX-2.5/NOPB is supplied in bulk packaging, while LP38692MP-2.5/NOPB is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated pick-and-place assembly and high-volume production. Bulk packaging is typically used for manual assembly or lower-volume applications.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected. They carry identical moisture sensitivity levels (MSL 1 - Unlimited) and environmental certifications.

Q: Why is the original part marked as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand and production decisions. The LP38692MP-2.5/NOPB remains in active production and provides full functional equivalence for all applications previously served by the obsolete variant.

Q: Are the electrical characteristics identical?

A: Yes. Both parts deliver 1A output at 2.5V fixed output, operate across -40°C to 125°C, maintain 1.3V maximum dropout voltage at rated load, and provide 55dB PSRR at 120Hz. Quiescent current and all protection features are identical.
