EC3AB25H Equivalent & Substitute Parts Reference

Part Overview

The EC3AB25H by Cincon Electronics Co. LTD is an active, isolated DC-DC converter module designed for ITE (Commercial) applications. It delivers dual outputs of +12V and -12V at a maximum current of 125mA each, with an input voltage range of 18V to 36V and 3W total output power. The part features 3 kV isolation, meets RoHS3 and REACH standards, and is housed in a 24-DIP module with through-hole mounting. Situations such as supply constraints or design updates may necessitate identifying fully compatible substitute models.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DC-DC converter category are identified strictly on the basis of matching the key electrical and mechanical parameters, including input voltage range, output voltages and currents, power rating, isolation voltage, operating temperature, mounting type, and package details. Compliance with relevant standards and agency approvals is also strictly observed. Only parts with equivalent or stricter adherence to these parameters are included. For EC3AB25H, the following parameters are used for direct substitution: dual +/-12V outputs, 18-36V input range, 3W power rating, 125mA output max (per channel), 3 kV isolation, through hole mounting, 24-DIP module package, supported compliance, and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Both EC3AB25H and EC3A25H are active products, RoHS3 compliant, and REACH unaffected. Both possess identical core electrical parameters, mechanical package, mounting type, approval agency certifications, and compliance. Certification to CE and cURus is explicitly listed for both parts. Only minor differences in physical height and efficiency are present; all mandatory compliance requirements and relevant operating parameters align for substitution.

Frequently Asked Questions (FAQ)

Q: Which parameters are most critical when selecting a substitute for EC3AB25H?
A: Input voltage range, output voltages and currents, total power rating, isolation voltage, mounting type, package, agency approvals, and compliance (RoHS3, REACH) are the critical parameters for substitution.

Q: Is EC3A25H physically compatible with the EC3AB25H footprint?
A: Both parts share the 24-DIP module case and 14-lead through-hole configuration, sizes differ minimally in height only.

Q: Are there differences in output or certifications that affect substitution?
A: There are no differences in output voltages, output current rating, or agency approvals (both CE, cURus). Compliance status is identical.

Q: Are there temperature rating limitations when substituting EC3AB25H with EC3A25H?
A: Both parts are rated for -25°C to 71°C operating temperature.

Q: Are both EC3AB25H and EC3A25H compliant with international environmental standards?
A: Both parts are RoHS3 compliant and REACH unaffected.

Q: Is substitute selection affected by the part’s inventory status?
A: Substitution is based on technical parameters, compliance, and certifications only; inventory status does not affect technical compatibility.
