LM2941CS Equivalent & Substitute Parts Reference

Part Overview

The LM2941CS is a linear voltage regulator IC designed for positive, adjustable output with a maximum output current of 1A, commonly used in power management applications. It features an enable control input and protection mechanisms including over temperature, reverse polarity, and short circuit protection. Packaged in a surface-mount TO-263 (DDPAK-5), it handles input voltages up to 26V and outputs voltages in the 5V to 20V range. The LM2941CS is classified as obsolete, necessitating the identification of equivalent and substitute models for continued design support and maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped based on strict equivalence or compatibility with the following key electrical and mechanical parameters: output configuration (positive), output type (adjustable), number of regulators (1), maximum input voltage (26V), voltage output range, voltage dropout, output current, control features, protection features, operating temperature range, mounting type, package/case, RoHS status, MSL, and REACH status. Substitute parts are listed only if these parameters align with the LM2941CS as explicitly provided.

Parameter Comparison

Engineering Selection Recommendations

The LM2941CS is classified as obsolete. The LM2941CS/NOPB is listed with the same manufacturer, identical electrical and mechanical parameters, and is ROHS3 compliant with the same MSL and REACH status, supporting direct form-fit-function replacement. The MIC29372WU is an active product, also ROHS3 compliant and shares similar package and mounting parameters.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to determine substitute compatibility for LM2941CS?
A1: Substitute compatibility is strictly determined by output configuration, output type, number of regulators, input voltage, output voltage range, dropout voltage, output current, control and protection features, operating temperature, mounting type, package/case, RoHS status, MSL, and REACH status.

Q2: Are the substitute parts form-fit-function compatible?
A2: LM2941CS/NOPB provides identical form, fit, and function based on the supplied parameters. MIC29372WU matches key parameters but has differences in output current and output voltage range.

Q3: Are the package and mounting types equivalent for all suggested substitutes?
A3: All parts use surface mount technology and TO-263-6, D2PAK (5 Leads + Tab), TO-263BA packaging or equivalent supplier device package.

Q4: Are all substitutes RoHS compliant and meet the same moisture sensitivity requirements?
A4: All substitutes listed are ROHS3 compliant and share a Moisture Sensitivity Level (MSL) of 3 (168 Hours).

Q5: What protection features differ between these parts?
A5: LM2941CS and LM2941CS/NOPB include over temperature, reverse polarity, and short circuit protection. MIC29372WU features over current and over temperature protection.
