Equivalent & Substitute Parts Reference: RB-053.3D

Part Overview

The RB-053.3D from Recom Power is an active isolated DC-DC converter module with dual outputs (+3.3V, -3.3V), rated at 1W total output power and 152mA per output channel. It features through-hole mounting in a 7-SIP module package and is designed for ITE (Commercial) applications. Alternate models may be necessary in cases of inventory limitation, supply chain changes, or design standardization requiring substitutes with matching electrical, mechanical, and compliance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute eligibility in the DC-DC converter isolated module category is determined exclusively by matching the following key parameters: number of outputs, output voltage ratings, maximum input voltage range, output current, output power, voltage isolation, mounting type, physical package, and compliance certifications. Substitute parts must also reflect equivalent operating temperature rating and RoHS/REACH compliance to ensure direct form-fit-function compatibility.

Parameter Comparison

Engineering Selection Recommendations

Selection among DC-DC isolated modules such as RB-053.3D or A0503S-1WR3 should be strictly based on product status (active), RoHS and REACH compliance, and applicable certifications as shown. Both parts are in active status, are RoHS compliant, and have unlimited moisture sensitivity levels. Certifications for A0503S-1WR3 include CB, CE, and cURus, which may fulfill standard regulatory requirements in commercial ITE applications.
