EC3AW12M Equivalent & Substitute Parts

Part Overview

The EC3AW12M is an isolated module DC-DC converter manufactured by Cincon Electronics Co. LTD, designed for commercial ITE applications. This 3W converter accepts input voltages from 18V to 72V and delivers a regulated 12V output at 250mA maximum current. The device features 500V isolation, short-circuit protection (SCP), and operates across the temperature range of -25°C to 71°C with 77% efficiency.

The EC3AW12M is classified as an active product with full RoHS3 compliance and CE approval. Substitute parts are identified based on matching electrical specifications, isolation characteristics, output ratings, and mechanical form factors that ensure direct functional equivalence in target applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EC3AW12M are identified through parametric equivalence matching. The substitution logic is based on the following critical parameters that must remain constant across all equivalent devices:

Electrical Specifications:

• Input voltage range: 18V to 72V
• Output voltage: 12V
• Maximum output current: 250mA
• Power rating: 3W
• Isolation voltage: 500V

Mechanical and Form Factor Requirements:

• Mounting type: Through Hole
• Package configuration: 24-DIP Module, 14 Leads
• Physical dimensions: 1.25" L × 0.80" W × 0.40" H

Operational and Compliance Requirements:

• Operating temperature range: -25°C to 71°C
• Efficiency: 77%
• Protection features: Short-Circuit Protection (SCP)
• RoHS3 compliance
• CE approval

Parts meeting all these parameters are classified as direct parametric equivalents and may be substituted without circuit redesign or application re-qualification.

Parameter Comparison

Engineering Selection Recommendations

Both the EC3AW12M and EC3AW12 are active products from Cincon Electronics Co. LTD with identical electrical, mechanical, and compliance characteristics. Selection between these parts is based on availability and supply chain considerations rather than technical differentiation.

Compliance and Certification Status: Both parts carry CE approval and ROHS3 compliance certification, confirming suitability for commercial ITE applications. Both maintain REACH Unaffected status and are classified under ECCN EAR99 for export purposes.

Inventory Availability: The EC3AW12 variant maintains higher inventory levels (15,200 pieces) compared to the EC3AW12M (941 pieces), making it the preferred selection for high-volume procurement or extended lead-time mitigation.

Functional Equivalence: The EC3AW12 provides complete functional equivalence to the EC3AW12M across all specified parameters. Direct substitution is supported without circuit modification, PCB redesign, or application re-qualification.

Frequently Asked Questions (FAQ)

Q: Can the EC3AW12 be used as a direct replacement for the EC3AW12M?

A: Yes. The EC3AW12 is a parametric equivalent with identical electrical specifications (18V-72V input, 12V/250mA output, 3W power rating, 500V isolation), mechanical form factor (24-DIP Module, 14 Leads, Through Hole mounting), operating temperature range (-25°C to 71°C), and compliance certifications (CE, ROHS3). Direct substitution is supported without circuit redesign.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution eligibility is determined by matching: input voltage range (18V-72V), output voltage (12V), maximum output current (250mA), power rating (3W), isolation voltage (500V), mounting type (Through Hole), package configuration (24-DIP Module, 14 Leads), physical dimensions (1.25" L × 0.80" W × 0.40" H), operating temperature range (-25°C to 71°C), and protection features (SCP). All parameters must match exactly.

Q: Are there any differences in packaging between the EC3AW12M and EC3AW12?

A: Both parts are supplied in Tube packaging with identical mechanical specifications. The 24-DIP Module configuration with 14 Leads and Through Hole mounting ensures identical PCB footprint and assembly compatibility.

Q: What is the isolation voltage specification, and why is it important?

A: Both parts provide 500V isolation voltage, which defines the maximum potential difference that can be safely applied between input and output circuits. This specification is critical for safety-critical applications and must remain constant for equivalent substitution.

Q: Do both parts meet the same compliance and certification standards?

A: Yes. Both the EC3AW12M and EC3AW12 carry CE approval, ROHS3 compliance, REACH Unaffected status, and are classified under ECCN EAR99. Compliance profiles are identical.

Q: What is the operating temperature range, and are both parts rated identically?

A: Both parts operate across -25°C to 71°C. This temperature range is identical for both variants and must be verified against application requirements before selection.

Q: Is there a difference in efficiency between the two parts?

A: No. Both parts deliver 77% efficiency under specified operating conditions. Efficiency ratings are identical.

Q: What protection features are included in both parts?

A: Both parts include Short-Circuit Protection (SCP), which provides automatic shutdown or current limiting in the event of output short-circuit conditions. This feature is identical across both variants.
