LP3853ET-5.0 Equivalent & Substitute Parts Reference

Part Overview

The Texas Instruments LP3853ET-5.0 is a linear voltage regulator IC under the Power Management (PMIC) category. It delivers a fixed 5V output at up to 3A with through-hole mounting (TO-220-5 package). Its maximum input voltage is 7V, and it offers protection features such as over current, over temperature, and short circuit, as well as an enable control function. The LP3853ET-5.0 has been classified as obsolete; therefore, it is necessary to identify alternative or equivalent models for continued production, field support, and maintenance purposes.

Substitute Part Grouping Explanation

Substitutes for the LP3853ET-5.0 are grouped according to strict parametric equivalence in the following areas: manufacturer (Texas Instruments), Power Management (PMIC) category, fixed positive output, 1 regulator, input voltage (max 7V), output voltage (5V fixed), dropout voltage (0.6V @ 3A), output current capacity (3A), enable control feature, protection against overcurrent, overtemperature, short circuit, operating temperature range (-40°C to 125°C), through-hole TO-220-5 package, supply current/specs, RoHS/REACH/moisture classification, and related export codes. Only devices matching all listed specifications and package attributes are considered substitutes.

Key parameters used for substitution:

• Output voltage
• Output current
• Dropout voltage
• Package and mounting type
• Control and protection features
• Operating temperature range
• Compliance (RoHS, REACH, MSL, ECCN)

Parameter Comparison

Engineering Selection Recommendations

The LP3853ET-5.0 is obsolete and RoHS non-compliant. The LP3853ET-5.0/NOPB and LP3856ET-5.0/NOPB are both active products, belonging to the same manufacturer and category, and match all key functional, electrical, and mechanical parameters. Both substitute parts are ROHS3 compliant, REACH unaffected, and have the same Moisture Sensitivity Level (1 - Unlimited). Either substitute can be directly considered for applications requiring ongoing RoHS compliance and supply chain continuity.

Frequently Asked Questions (FAQ)

Q1: What is the primary consideration when selecting a substitute for the LP3853ET-5.0?
A1: The primary factors are functional equivalence in voltage regulation parameters, output current rating, package type, protection and control features, and regulatory compliance (RoHS, REACH, MSL).

Q2: Are the package and mounting type of substitute parts equivalent to the original LP3853ET-5.0?
A2: Yes, all listed substitutes use the TO-220-5 Formed Leads package for through hole mounting, matching the mechanical and assembly requirements of the LP3853ET-5.0.

Q3: Do the substitute parts support the same output voltage and current specifications?
A3: Yes, both LP3853ET-5.0/NOPB and LP3856ET-5.0/NOPB provide a fixed 5V output at up to 3A, with the same dropout voltage.

Q4: Are the substitute parts compliant with latest RoHS and REACH requirements?
A4: Both LP3853ET-5.0/NOPB and LP3856ET-5.0/NOPB are ROHS3 compliant and REACH unaffected.

Q5: Is there any difference in protection, control, or performance features among the substitutes?
A5: All listed substitutes provide enable control, and protection features including over current, over temperature, and short circuit, identical to the original LP3853ET-5.0.
