Equivalent & Substitute Parts for MYLG100503ERNB

Part Overview

The MYLG100503ERNB is a DC-DC converter from Murata Electronics, categorized as a Non-Isolated Point-of-Load (PoL) Module. This device provides a single adjustable output voltage from 0.591V to 5.5V at up to 3A continuous output current, with an input voltage range of 4.5V to 14V, 17W maximum output power, and an efficiency of 93%. It features overcurrent protection (OCP), overtemperature protection (OTP), short circuit protection (SCP), and undervoltage lockout (UVLO), designed for ITE (Commercial) applications. The device is supplied in a 12-SMD surface mount package. The MYLG100503ERNB is currently listed as obsolete; therefore, it is necessary to identify functionally equivalent and mechanically compatible substitute parts to support ongoing designs, ensure manufacturing continuity, and satisfy maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute DC-DC converter module selection for MYLG100503ERNB has been strictly limited to parts matching the following key parameters: Non-Isolated PoL Module type, single output, overlapping or identical input and output voltage ranges, maximum current rating of at least 3A, surface mount 12-SMD (or compatible) package, similar features (OCP, OTP, SCP, UVLO), comparable efficiency, and compatible mechanical dimensions. Only parameters provided in the input have been considered to ensure strict compatibility without extrapolation.

Parameter Comparison

Engineering Selection Recommendations

Engineering selection preference should be given to substitute DC-DC converter modules with active status (OKL-T/3-W12N-C, LMZ10504TZX-ADJ/NOPB) to ensure ongoing supply chain reliability. RoHS status, MSL rating, and REACH status have been documented where provided in the supplied product data for compliance tracking. Obsolescence status indicates replacement necessity for MYLG100503ERNB in both new and sustaining designs.

Frequently Asked Questions (FAQ)

Q1: What are the main substitution criteria for MYLG100503ERNB?
A1: The main substitution criteria are matching type (Non-Isolated PoL Module), number of outputs (1), compatible input and output voltage ranges, output current, protection features, efficiency, operating temperature, package type, mounting style, and dimensions.

Q2: Are the package types and sizes compatible among substitutes?
A2: The OKL-T/3-W12N-C matches the 12-SMD surface mount package and physical dimensions of MYLG100503ERNB. The LMZ10504TZX-ADJ/NOPB uses the TO-PMOD-7, Power Module package with smaller footprint and different dimensions; compatibility depends strictly on the supplied parameters.

Q3: Do substitutes maintain regulatory and environmental compliance?
A3: Substitutes provide documentation of RoHS and REACH status, as well as MSL ratings, as supplied in the input data. Selection should consider these attributes for compliance in regulated industries.

Q4: Are substitute parts currently available for production needs?
A4: According to the supplied inventory data, both OKL-T/3-W12N-C and LMZ10504TZX-ADJ/NOPB are listed as 'Active' with available stock.

Q5: Which features are required for substitution compatibility?
A5: Substitute features must include OCP (overcurrent protection), OTP (overtemperature protection), SCP (short circuit protection), and UVLO (undervoltage lockout), as listed in the input.

Q6: How does efficiency of substitutes compare?
A6: OKL-T/3-W12N-C matches the efficiency specification of the MYLG100503ERNB. LMZ10504TZX-ADJ/NOPB provides higher efficiency as per supplied input parameters.
