EC3AB31M Equivalent & Substitute Parts

Part Overview

The EC3AB31M is an isolated module DC-DC converter manufactured by Cincon Electronics Co. LTD, designed for commercial ITE applications. This 3W converter accepts input voltages between 36V and 72V and delivers a regulated 5V output at 600mA 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 EC3AB31M is classified as an active product with current inventory availability. Identifying equivalent and substitute parts is necessary for supply chain continuity, design flexibility, and procurement optimization when the primary part number becomes unavailable or when alternative sourcing is required.

Substitute Part Grouping Explanation

Substitution eligibility for the EC3AB31M is determined by strict parametric equivalence across all critical electrical and mechanical specifications. The following parameters establish the substitution criteria:

Electrical Parameters:

  • Input voltage range: 36V minimum to 72V maximum
  • Output voltage: 5V
  • Maximum output current: 600mA
  • Power rating: 3W
  • Isolation voltage: 500V
  • Operating temperature range: -25°C to 71°C
  • Efficiency: 77%

Mechanical Parameters:

  • Mounting type: Through Hole
  • Package type: 24-DIP Module, 14 Leads
  • Physical dimensions: 1.25" L × 0.80" W × 0.50" H

Compliance Parameters:
