Equivalent & Substitute Parts Reference: MTU2S2405MC

Part Overview

The MTU2S2405MC is an isolated DC-DC converter module manufactured by Murata Power Solutions Inc. It features a single 5V output at a maximum current of 400mA, operating from a 21.6V to 26.4V input range, and provides a power rating of 2 W. The product is constructed in a surface mount 6-SMD package and designed for ITE (Commercial) applications. This part is classified as obsolete, necessitating the selection of alternative models to ensure continued production, maintenance, and design compatibility.

Substitute Part Grouping Explanation

Substitute parts for the MTU2S2405MC are identified strictly by matching the following mandatory electrical and environmental parameters: input voltage range (21.6V to 26.4V), output voltage (5V), output current (400mA), power rating (2 W), mounting type (surface mount), application suitability (ITE (Commercial)), RoHS compliance, and REACH status. Packaging and product status are also considered to ensure compatibility and continued availability. Only parts meeting or exceeding these criteria are grouped as substitutes.

Engineering Selection Recommendations

The MTU2S2405MC is listed as obsolete, making inventory-dependent procurement unsustainable for ongoing production and new designs. NXJ2S2405MC-R7 from Murata Power Solutions Inc. maintains active production status and matches all compliance requirements, including ROHS3 and REACH. Selection should prioritize substitutes with similar certification and compliance profiles to meet regulatory and environmental requirements.

Frequently Asked Questions (FAQ)

Which electrical parameters must match for substitution of DC-DC converter modules?
Only voltage input range, output voltage, output current, and power rating are used as substitution criteria.

Are mounting type and package relevant for DC-DC converter substitution?
Yes, matching the mounting type and package ensures physical compatibility in assembly and layout.

Is it necessary for substitute parts to hold active status?
Active production status is required for long-term availability and supply chain stability.

How does compliance with ROHS and REACH affect substitute selection?
Only substitutes with ROHS3 compliance and unaffected REACH status meet required environmental regulations.

Can parts with higher isolation voltage or additional application suitability be used as substitutes?
Substitution is accepted if the part matches the required application (ITE (Commercial)) and exceeds necessary isolation voltage, provided all other key parameters align.

Does a change in efficiency between parts affect substitution validity?
Efficiency is compared for reference only; substitution is based on matching required electrical and environmental parameters as listed.
