RAC20-12DA Equivalent & Substitute Parts Reference

Part Overview

The Recom Power RAC20-12DA is an enclosed AC/DC converter designed to provide two outputs of 12V at 833mA each, with a total output power of 20 W. It accepts an input voltage range of 90 ~ 264 VAC and is used in ITE (Commercial) applications. The RAC20-12DA is now classified as obsolete, necessitating the identification of alternative models to support ongoing applications and product designs that require equivalent functionality, regulatory compliance, and electrical performance.

Substitute Part Grouping Explanation

Substitution of AC/DC converter models within the same product category is based strictly on the following allowed parameters: input voltage range, output voltage(s), maximum output current, total power output, number of outputs, efficiency, operating temperature range, mounting type, package/case dimensions, regulatory approvals, RoHS status, moisture sensitivity level, and REACH status. Only parts matching or exceeding these parameters are listed as valid substitutes.

Engineering Selection Recommendations

RAC20-12DA is classified as obsolete. RAC20-12DK is available and active. Both models are RoHS3 compliant and have equivalent or enhanced regulatory approvals. RAC20-12DK meets REACH standards and has an identical moisture sensitivity level. Substitute selection is based on current product availability, equivalent compliance status, and maintained or expanded certifications.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for substituting RAC20-12DA with RAC20-12DK?
A1: Substitution is based on matching electrical output (voltage, current), power rating, input voltage range, number of outputs, compliance certifications, RoHS and REACH status, moisture sensitivity, and mounting/package type.

Q2: Are there differences in package dimensions or mounting between RAC20-12DA and RAC20-12DK?
A2: RAC20-12DA and RAC20-12DK both utilize through-hole mounting, but differ in package/case dimensions and the number of DIP module leads. Mechanical fit should be verified based strictly on the given size and package data.

Q3: Can RAC20-12DK be used in the same application categories as RAC20-12DA?
A3: Both parts are suitable for ITE (Commercial) applications as specified in the provided parameters.

Q4: What regulatory certifications are relevant for substitution?
A4: Both parts provide CE certification and North American safety certification (cULus for RAC20-12DA; cURus and CB for RAC20-12DK), ensuring compatibility where these approvals are required.

Q5: Is RoHS and REACH compliance maintained in the substitute part?
A5: Both RAC20-12DA and RAC20-12DK are ROHS3 compliant and REACH unaffected, ensuring substitution does not impact environmental compliance requirements.
