Equivalent & Substitute Parts for EC3AB21M

Part Overview

The EC3AB21M, manufactured by Cincon Electronics Co. LTD, is an isolated module DC-DC converter delivering a single 5V output at up to 600mA from an input range of 18V to 36V, rated for 3W output power. With through-hole mounting in a 24-DIP Module (14 leads) package, this product features 500V isolation, SCP (Short Circuit Protection), and is designed for ITE (Commercial) applications. It is currently classified as “Active”, with ROHS3 compliance and an unlimited MSL rating. Substitution of alternative models such as EC3AB21 is necessary for ensuring continued production, supply chain management, and engineering design flexibility when identical functional and regulatory characteristics are required.

Key Parameters

Substitute Part Grouping Explanation

Substitute DC-DC converter models are grouped strictly by full parametric equivalence in electrical and mechanical characteristics. The key parameters used for determining equivalence include: Manufacturer, Series, Input Voltage Range (18V – 36V), Output Voltage (5V), Output Current (600mA), Power Rating (3W), Output Count (1), Isolation Voltage (500V), Application Class (ITE Commercial), Feature Set (SCP), Operating Temperature Range (-25°C to 71°C), Efficiency (77%), Mounting Type (Through Hole), Package/Case (24-DIP Module, 14 leads), Size/Dimension, RoHS compliance, MSL, and REACH Status. Substitute EC3AB21 is included because it precisely matches these criteria.

Parameter Comparison

Engineering Selection Recommendations

When selecting between EC3AB21M and EC3AB21, product status, RoHS3 compliance, and REACH status are matched. Both options are classified as Active, ensuring ongoing availability. MSL rating is 1 (Unlimited), suitable for all standard production handling and storage conditions. Either model can be selected based on stock availability without deviation in compliance or functional characteristics.
