Equivalent & Substitute Parts Reference for AE5-EW-S5

Part Overview

The AE5-EW-S5 by CUI Inc. is an active isolated module DC-DC converter delivering a single 5V output at up to 1A, rated for 5W total power, and designed for ITE (Commercial) applications. It supports a wide input voltage range (100V – 1000V), 4 kV isolation, and includes protection features (OCP, OVP, SCP). Finding alternative models is sometimes necessary for supply continuity, lead time management, or compliance with specific project requirements. Suitable substitutes must match the main electrical and mechanical parameters as listed below.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts within this DC-DC converter category must precisely match key parameters: isolated module type, single 5V output, maximum output current of 1A, power rating of 5W, and through-hole mounting. Other critical requirements are the application fit (ITE Commercial), active product status, RoHS compliance, and protective features (SCP, OCP, OVP where noted). Only parts explicitly specified with these matching attributes are acceptable substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both AE5-EW-S5 and REC5-2405SRWZ/H2/A are listed as active parts with RoHS-compliant status. Each part is suited for ITE (Commercial) applications based on the parameters provided. Substitution is based strictly on the explicit parameters and current compliance certifications.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for substituting DC-DC converters in this category?
A1: Main criteria include output voltage and current, power rating, module type, mounting type, isolation voltage, application classification, protective features, and current product/inspection compliance status.

Q2: Are the pin configurations and packages identical between AE5-EW-S5 and REC5-2405SRWZ/H2/A?
A2: The provided data specifies mounting type as through-hole for both parts, but package/case dimensions and formats differ. AE5-EW-S5 is in a 5-DIP module and REC5-2405SRWZ/H2/A is in a 24-DIP module.

Q3: Is voltage isolation critical to substitution in this instance?
A3: The explicit parameter for voltage isolation is 4 kV for AE5-EW-S5 and 2 kV for REC5-2405SRWZ/H2/A. Substitution should only be considered where this variance is acceptable to the specific application.

Q4: Do both converters meet RoHS compliance?
A4: Both AE5-EW-S5 and REC5-2405SRWZ/H2/A are RoHS compliant as per the provided data.

Q5: Are there differences in protective features?
A5: AE5-EW-S5 lists OCP, OVP, and SCP, whereas REC5-2405SRWZ/H2/A lists SCP only. Selection depends on project requirements for overcurrent, overvoltage, and short-circuit protection.
