LXDC55BAAC-158 Equivalent & Substitute Parts Reference

Part Overview

The Murata Electronics LXDC55BAAC-158 is a Non-Isolated PoL DC-DC Converter Module designed for ITE (Commercial) applications. It provides a single 1.8V output at up to 3A from a 2.7V–5.5V input voltage range and features OCP and UVLO protection, surface mount package, and a compact footprint. The product is now Obsolete, making it critical to identify suitable alternative models to ensure continuity of design and supply.

Key Parameters

Substitute Part Grouping Explanation

Equivalence is determined strictly by those key parameters that enable the alternate part to provide similar form, fit, and function. The substitute part must match the surface mount configuration, be RoHS compliant (Moisture Sensitivity Level: 1), and operate within the same temperature range. Product status and compliance attributes are also considered. Only parts explicitly provided as substitutes are included.

Key substitution parameters:

• Mounting Type
• Operating Temperature
• Moisture Sensitivity Level (MSL)
• Product Status

Parameter Comparison

Engineering Selection Recommendations

Selection based only on the parameters provided: LXDC55BAAC-158 is obsolete, indicating a requirement for substitution. MRF24J40MD-I/RM is active and shares identical MSL and temperature ratings, meeting lead-free compliance stated by RoHS3. No further compliance or product certifications are listed.

Frequently Asked Questions (FAQ)

Q: On what basis is MRF24J40MD-I/RM considered for substitution?
A: MRF24J40MD-I/RM is included strictly as an explicit substitute part. It matches on surface mount configuration, operating temperature range, and RoHS-compliant moisture sensitivity level.

Q: Are key form factor and temperature operating ranges a match?
A: Yes. Both LXDC55BAAC-158 and MRF24J40MD-I/RM utilize surface mount technology and support -40°C to 85°C operation.

Q: Are packaging and compliance requirements consistent?
A: Both models meet MSL 1 (Unlimited) and are RoHS compliant.

Q: Does the substitute preserve all electrical and mechanical parameters?
A: All only parameters explicitly listed are considered. Additional deviations are not evaluated beyond the provided information.

Q: Can existing PCB layouts be used without modification?
A: The answer is determined strictly by common mounting type. No other mechanical compatibility or footprint data was provided.
