Equivalent & Substitute Parts for EC3A03M

Part Overview

The Cincon Electronics Co. LTD EC3A03M is an active isolated module DC DC converter classified under the 3W EC3A series. It features a single output of 15V at a maximum output current of 200mA and accepts an input voltage range of 4.5V to 6V. This converter offers 500V isolation and is equipped with short-circuit protection (SCP). It is mounted via through-hole assembly in a 24-DIP Module, 14 Leads package, and supports an operating temperature of -25°C to 71°C. When original parts are out of stock or when supply constraints exist, it becomes necessary to identify substitute or equivalent models with precisely matching key attributes to ensure continued system reliability and compliance.

Substitute Part Grouping Explanation

Substitution for a DC DC converter within the EC3A series is strictly permitted when the following key parameters match exactly: part number, input voltage range, output voltage, maximum output current, isolation voltage, power rating, features, package type, mounting style, size/dimension, efficiency, regulatory compliance, operating temperature range, and application classification. For EC3A03M, only EC3A03 from the same manufacturer is specified as an equivalent based on identical electrical, mechanical, and compliance attributes.

Parameter Comparison

Engineering Selection Recommendations

Selection between EC3A03M and the parametric equivalent EC3A03 is based solely on the matching product status (“Active”), regulatory certifications (ROHS3 Compliant, REACH Unaffected), and identical technical parameters within the provided product category. The substitute part EC3A03 satisfies all listed requirements with no variance in provided certifications or compliance.

Frequently Asked Questions (FAQ)

Q1: What are the strict substitution criteria for DC DC converter EC3A03M?
