LME0505SC Equivalent & Substitute Parts Reference
Part Overview
The Murata Power Solutions Inc. LME0505SC is an isolated module DC-DC converter with a single 5V output and a maximum output current of 50mA, designed for ITE (commercial) applications. It offers 250mW power, 1kV isolation voltage, operates from a 4.5V–5.5V input, and features short-circuit protection (SCP). The device is obsolete, necessitating the identification of alternative models for ongoing or new designs requiring its electrical and mechanical parameters.

Substitute Part Grouping Explanation
Substitute parts are included based on strict compliance with the following key parameters: isolated module type, one output, identical input voltage range (4.5V–5.5V), required output voltage (5V), supporting current at least 50mA, minimum power rating 250mW, 1kV isolation voltage, mounting as through hole, 4-SIP module package, ITE (commercial) application, and matching compliance status (ROHS3, REACH, EAR99). Only parts fulfilling all these criteria and having similar mechanical size and features are listed as substitutes.

Engineering Selection Recommendations
The primary reason for selecting substitute parts for LME0505SC is its obsolete product status. Both CRE1S0505SC and RM-0505S are active and ROHS3 compliant, with unaffected REACH status and identical ECCN and HTSUS codes. Both substitutes maintain the required regulatory compliance and environmental certifications as specified for direct replacement in qualified commercial ITE designs.
Frequently Asked Questions (FAQ)
Q: What are the strict substitution criteria for the LME0505SC?
A: Substitute parts must match input voltage, output voltage, isolation rating, output current with at least 50mA capability, mounting type, package type, application category, and compliance status.
Q: Do the substitute models CRE1S0505SC and RM-0505S maintain package compatibility?
A: Both models use the 4-SIP Module package and through-hole mounting, matching the size and layout requirements of the LME0505SC.
Q: Is there any compliance difference between the original and substitute parts?
A: All parts are ROHS3 compliant, REACH unaffected, ECCN EAR99, and have identical HTSUS classification.
Q: Can higher current parts like CRE1S0505SC be used in place of the LME0505SC?
A: Substitution is confirmed based strictly on required minimum electrical and mechanical properties; excess current capacity is permitted within the supported range.
Q: Are substitute parts suitable for the same ITE (commercial) applications?
A: Each substitute matches the confirmed application category as specified in the provided parameters.
Q: Is short-circuit protection (SCP) required for substitution?
A: RM-0505S supports SCP as specified; CRE1S0505SC does not list SCP under its features in the provided parameters.
Q: Do the substitute devices fit within the same board layout area as the LME0505SC?
A: All substitute devices conform to the specified size and dimension requirements making them mechanically compatible.
