EC3AB37H Equivalent & Substitute Parts Reference

Part Overview

The Cincon EC3AB37H is an active isolated DC-DC converter module designed for ITE (Commercial) applications. This product delivers a regulated 3.3V output at up to 600mA from a wide 36V–72V input range, supporting 2W output power with 3kV isolation and through-hole mounting in a 24-DIP, 14-lead format. When supply continuity, compliance, or mechanical fitment is critical, identifying substitute components with precisely matching electrical and mechanical parameters is essential.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection is determined strictly by matching these electrical and mechanical parameters: manufacturer, input voltage range, output voltage and current, power rating, isolation voltage, package type and dimensions, mounting style, application, compliance (RoHS, REACH), operating temperature, agency approvals, and part status. Only parts with identical or equivalent values for all listed fields are included. No assumptions or recommendations are made beyond provided parameters.

Parameter Comparison

Engineering Selection Recommendations

The EC3AB37H and EC3A37H are both active and RoHS3 compliant, with REACH unaffected status and approvals from CE and cURus. Both deliver equivalent electrical performance in terms of voltage, current, power, isolation, and are packaged in 24-DIP through-hole formats. Selection between these is based on matching regulated output, input range, compliance specifications, and agency approvals, as explicitly provided.

Frequently Asked Questions (FAQ)

Q1: What substitution criteria are used for EC3AB37H?
Only parameters explicitly listed for both main and substitute parts—such as electrical ratings, mechanical dimensions, regulatory compliance, and approvals—are considered.

Q2: Is the package format compatible between EC3AB37H and EC3A37H?
Both use a 24-DIP Module with 14 leads. Dimensional differences (height: 0.50" vs. 0.40") are noted; suitability must match assembly requirements based on provided data.

Q3: Is there any difference in performance or compliance?
Both have identical compliance (RoHS3, REACH) and approval agencies (CE, cURus). The substitute part lists slightly higher efficiency (72% vs. 71%).

Q4: Are both parts suitable for ITE (Commercial) applications?
Yes. Applications listed match for both parts.

Q5: Does substitute selection consider operating temperature?
Yes. Both parts specify -25°C ~ 71°C.

Q6: Are both parts supplied in tube packaging?
Yes. Tube packaging is specified for both EC3AB37H and EC3A37H.

Q7: Can EC3A37H directly replace EC3AB37H in all cases?
Per provided parameters, EC3A37H matches the key criteria for direct substitution within the scope of listed specifications.
