KAS2-5 Equivalent & Substitute Parts Reference

Part Overview

The TDK-Lambda Americas Inc KAS2-5 is an AC/DC converter specified for enclosed applications requiring a 5V, 2W regulated output from a 90–305 VAC input range. It offers a single output at 400mA maximum current for ITE (Commercial) applications and is housed in a 5-DIP module through-hole package. The product is classified as obsolete, necessitating the identification of suitable alternative AC/DC converter modules to maintain design compatibility and ensure continued supply.

Key Parameters

Substitute Part Grouping Explanation

Substitute AC/DC converter modules for KAS2-5 are selected strictly based on the following parameters:

• Output voltage of 5V
• Input voltage range covering at least 90–305 VAC
• Equal or greater maximum output current and power rating
• Enclosed type construction
• Through-hole mounting and DIP module package form factor
• Single output
• Compliance with relevant RoHS and safety certifications

All substitutes presented match or exceed these specified electrical, mechanical, and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

Alternative parts should be selected based on active product status to ensure ongoing availability. Compliance with RoHS and safety agency certifications, such as CE and cURus/UL, must align with the original application’s requirements. Substitute models meeting or exceeding the input range, output voltage, current, and power requirements, as well as electrical and mechanical compatibility, are suitable based on the supplied information.

Frequently Asked Questions (FAQ)

Q1: What are the key criteria for choosing a substitute for KAS2-5?
A1: The substitute part must have a 5V output, support an input range covering 90–305 VAC, provide at least 400mA output current, match the enclosed and through-hole format, and comply with relevant safety and RoHS requirements.

Q2: Are there differences in package or mounting style among the alternatives?
A2: All parts use through-hole mounting with DIP module packaging. The KAS2-5, BAC3S05DC, and TMPS 03-105 use 5-DIP modules, while KPSB6-5-E uses a 4-DIP module.

Q3: How do the efficiency and thermal ranges compare?
A3: Substitute parts offer efficiency from 72% to 78% and operating temperature ranges from at least -25°C to +85°C (with derating), meeting or exceeding the KAS2-5's specification.

Q4: Are size differences significant in the substitute options?
A4: Substitute modules have similar or slightly different dimensions. Review module dimensions and layout for physical compatibility in the target application.

Q5: Will the substitutes support regulatory compliance requirements?
A5: All listed substitutes hold RoHS compliance and recognized safety agency approvals as specified in the parameters provided.
