RAC30-05DA Equivalent & Substitute Parts Reference

Part Overview

The RAC30-05DA from Recom Power is an enclosed AC/DC converter with dual 5V outputs rated at 3A each, providing 30W total output power. This unit is designed for ITE (Commercial) applications and features short circuit protection (SCP), high-voltage AC input capability, and through hole mounting. The RAC30-05DA is classified as obsolete, making it necessary to identify alternative models to ensure continuity in designs that require similar mechanical and electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined strictly by matching required electrical and mechanical parameters, which include output voltage, output current, total power, input voltage range, number of outputs, mounting type, package/case, size/dimensions, operating temperature, efficiency, and relevant safety or environmental certifications. Only parts that meet or exceed each of these specification fields are included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The RAC30-05DA (Recom Power) is obsolete, and its specified substitute, KMD40-55 (TDK-Lambda Americas Inc), offers equivalent or greater output ratings and maintains consistent electrical, mechanical, and environmental compliance. The KMD40-55 holds relevant CE and RoHS certifications and matches the key mechanical and electrical interface for replacement in compatible systems. Product status for KMD40-55 is specified as "Not For New Designs."

Frequently Asked Questions (FAQ)

Q1: What are the primary electrical parameters required to select a substitute for RAC30-05DA?
A1: The substitute must have dual 5V outputs, each rated for at least 3A, support 90–264 VAC input voltage, and provide equal or greater total output power.

Q2: Can KMD40-55 be mounted in the same way as RAC30-05DA?
A2: Both models use through-hole mounting and share the 7-DIP Module, 5 Leads package, allowing for direct mechanical compatibility.

Q3: Are there any differences in certifications between RAC30-05DA and KMD40-55?
A3: Both possess CE and RoHS compliance. KMD40-55 also includes EN, IEC, and UL certifications.

Q4: Are there dimensional differences when replacing RAC30-05DA with KMD40-55?
A4: KMD40-55 is marginally taller at 1.06" H compared to 1.00" H, with length and width dimensions unchanged.

Q5: Is there any difference in output power or current capability between these two models?
A5: KMD40-55 provides higher output current (4A per output) and a higher total power rating (40W) versus 3A per output and 30W for RAC30-05DA.

Q6: Are both parts suitable for operation in the same temperature range?
A6: Both parts are rated for -25°C to 70°C operating temperature with derating.
