EC4AB04H Equivalent & Substitute DC DC Converter Reference

Part Overview

The Cincon Electronics EC4AB04H is an isolated DC DC converter module that delivers ±12V at 230mA per output, with a 5.5W maximum power rating. It accepts a 9V to 18V input range and is suitable for ITE (Commercial) applications. The device features 3kV isolation, SCP (Short Circuit Protection), and comes in a 24-DIP module, 14-lead through-hole package. The product is active and ROHS3 compliant.

Identifying equivalent and substitute DC DC converter models is essential for supply chain continuity, design flexibility, and MRO (maintenance, repair, operations) needs. Only components meeting identical or stricter electrical, mechanical, and compliance parameters are considered.

Parameter Comparison

Engineering Selection Recommendations

Both EC4AB04H and EC4A04H isolated DC DC converters are active, ROHS3 compliant, and covered by REACH status. They hold CE and cURus approvals. Both meet inventory and lifecycle management considerations for commercial and industrial electronic assemblies where substitute part selection requires matching electrical performance, regulatory compliance, and mounting specifications.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to determine equivalent and substitute DC DC converter parts?
A1: Equivalent and substitute parts are determined based on identical input/output voltages, output current, power rating, isolation voltage, number of outputs, mounting style, package case, feature set, compliance approvals, and operating temperature range.

Q2: Is the EC4A04H functionally compatible as a substitute for EC4AB04H?
A2: The EC4A04H is functionally compatible, as it matches all specified input and output voltage ranges, current, power, isolation, features, ITE (Commercial) application, and regulatory/compliance parameters.

Q3: Are there any mechanical differences between EC4AB04H and EC4A04H that will affect direct replacement?
A3: Both parts have a 24-DIP module, 14-lead through-hole package with identical length and width; EC4AB04H is 0.50" height (12.7mm), while EC4A04H is 0.40" height (10.2mm).

Q4: Are all listed substitutes compliant with ROHS3 and REACH?
A4: Yes, all listed substitute parts are ROHS3 compliant and REACH unaffected.

Q5: Does the efficiency differ between the EC4AB04H and EC4A04H DC DC converters?
A5: The EC4A04H has an efficiency of 83%, and the EC4AB04H has an efficiency of 81%, as specified. Both values are provided by the manufacturer.
