EC3AW05M Equivalent & Substitute Parts

Part Overview

The EC3AW05M is an isolated module DC-DC converter manufactured by Cincon Electronics Co. LTD, designed to deliver dual output voltages of +12V and -12V from a wide input range of 9V to 36V. This 3W converter is classified as an active product and is widely used in commercial ITE (Information Technology Equipment) applications requiring galvanic isolation and short-circuit protection.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits selection from functionally identical alternatives within the same product series.

Substitute Part Grouping Explanation

Substitution of DC-DC converter modules is determined by strict equivalence across electrical and mechanical parameters. The EC3AW05M and its substitute EC3AW05 are functionally identical isolated module converters within the same EC3AW series, sharing identical specifications for input voltage range (9V to 36V), dual output configuration (+12V and -12V), maximum output current (125mA per channel), power rating (3W), isolation voltage (500V), operating temperature range (-25°C to 71°C), and physical package dimensions (24-DIP Module, 14 Leads).

Substitution is valid when the following key parameters match exactly:

• Input voltage range (9V minimum, 36V maximum)
• Output voltage configuration (12V and -12V dual output)
• Maximum output current per channel (125mA)
• Power rating (3W)
• Isolation voltage (500V)
• Mounting type (Through Hole)
• Package type (24-DIP Module, 14 Leads)
• Physical dimensions (1.25" L x 0.80" W x 0.40" H)
• Compliance certifications (CE, ROHS3)

Parameter Comparison

Engineering Selection Recommendations

Both EC3AW05M and EC3AW05 are active products manufactured by Cincon Electronics Co. LTD and carry identical compliance certifications including CE approval and ROHS3 compliance status. The parts are electrically and mechanically equivalent, with no differentiation in electrical performance, isolation characteristics, or thermal operating range.

Selection between these parts should be based on inventory availability and supply chain considerations. The EC3AW05 variant currently maintains higher inventory levels (15,300 pieces) compared to EC3AW05M (1,036 pieces), making it the preferred choice for applications where supply continuity is a priority.

Both parts are suitable for direct substitution in commercial ITE applications requiring isolated dual-output power conversion with short-circuit protection. The 24-DIP through-hole package ensures compatibility with standard PCB layouts designed for either part number.

Frequently Asked Questions (FAQ)

Q: Can EC3AW05 be used as a direct replacement for EC3AW05M?

A: Yes. Both parts are functionally identical isolated module DC-DC converters with matching electrical specifications, output configurations, isolation voltage, operating temperature range, and physical package dimensions. Direct substitution is valid without circuit modification.

Q: What are the critical parameters that must match for substitution?

A: The following parameters must match exactly: input voltage range (9V to 36V), dual output voltages (+12V and -12V), maximum output current (125mA per channel), power rating (3W), isolation voltage (500V), mounting type (Through Hole), and package type (24-DIP Module, 14 Leads).

Q: Are there any compliance or certification differences between EC3AW05M and EC3AW05?

A: No. Both parts carry identical compliance certifications: CE approval, ROHS3 compliance, and REACH unaffected status. Both are classified as active products with no differences in regulatory standing.

Q: What is the physical footprint compatibility between these parts?

A: Both parts use the 24-DIP Module package with 14 leads and identical dimensions of 1.25" L x 0.80" W x 0.40" H (31.8mm x 20.3mm x 10.2mm). PCB layouts designed for either part number are fully compatible.

Q: Is there a performance difference in efficiency or thermal characteristics?

A: No. Both parts deliver 72% efficiency and operate across the identical temperature range of -25°C to 71°C. Thermal and power conversion performance is equivalent.

Q: What applications are these converters suitable for?

A: Both parts are designed for commercial ITE (Information Technology Equipment) applications requiring isolated dual-output power conversion with short-circuit protection. The 500V isolation voltage supports applications requiring galvanic isolation between input and output circuits.
