Equivalent & Substitute Parts for RSD-3.33.3

Part Overview

The Recom Power RSD-3.33.3 is a DC-DC converter in the ECONOLINE RSD (1W) series, designed as an isolated module providing two outputs: +3.3V and -3.3V at up to 152mA each. It supports input voltages from 3V to 3.6V and includes short-circuit protection (SCP), RoHS3 compliance, and unlimited moisture sensitivity. The RSD-3.33.3 is currently obsolete. Therefore, identifying substitute or equivalent parts is necessary to ensure continued production or field support without changing critical design elements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for DC-DC converter modules in the isolated dual output category is strictly based on the following parameters: input voltage range, output voltages, maximum output currents, isolation voltage, package type, mounting type, number of outputs, safety features (such as SCP), efficiency, and compliance (RoHS, REACH). Substitute parts are considered only if these criteria match exactly between the listed obsolete part and the available substitute.

Parameter Comparison

Engineering Selection Recommendations

Based on product status and regulatory compliance, the RSD-3.33.3 is obsolete while the R1D-3.33.3 is active and in stock. Both parts are ROHS3 compliant, unaffected by REACH, and have unlimited moisture sensitivity levels. These certifications meet standard requirements for ITE (Commercial) applications. Selection should be based strictly on ensuring continued compliance and availability, without altering specified parameters.

Frequently Asked Questions (FAQ)

What are the main selection criteria for substituting DC-DC converters in this category?

Substitute selection uses input voltage range, output voltage values, maximum output current, isolation voltage, number of outputs, mounting type, package, protection features, and regulatory compliance.

Can R1D-3.33.3 replace RSD-3.33.3 in existing designs?

Both parts match key electrical parameters and regulatory standards, and feature the same mounting type. Consider the slight difference in mechanical dimensions to verify physical compatibility within the intended PCB layout.

Does the substitute part support the same compliance standards as the original?

Both DC-DC converters are ROHS3 compliant, unaffected by REACH, rated ECCN EAR99, and have unlimited moisture sensitivity (MSL 1).

Are there differences in package dimensions between these two parts?

RSD-3.33.3 measures 0.60" L x 0.32" W x 0.29" H; R1D-3.33.3 measures 0.60" L x 0.42" W x 0.28" H. Check available PCB space for compatibility due to the difference in width and height.

Is there any difference in operating temperature range and efficiency?

The substitute R1D-3.33.3 extends the operating temperature to 100°C and increases efficiency to 75%. Confirm that these enhancements align with application requirements.
