RTS-153.3/HP Equivalent & Substitute Parts Reference

Part Overview

The RTS-153.3/HP is an isolated DC-DC converter module from Recom Power, providing a single 3.3V output at up to 606mA from a 13.5V to 16.5V DC input. This module, rated for 2W output power and 3kV isolation, is intended for applications in ITE (Commercial) and Medical sectors. It features short-circuit protection (SCP), operates in the -40°C to 85°C range, and is supplied in a compact 8-SMD Module (5 Leads) package suitable for surface mounting. The RTS-153.3/HP is currently categorized as obsolete, necessitating the identification of alternative models for direct substitutions in legacy designs and ongoing maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute components are grouped strictly according to identical key parameters in function, input/output range, power rating, isolation voltage, feature set, compliance status, and form factor. For DC-DC converters, primary substitution criteria include: number of outputs, voltage input range, output voltage, maximum output current, power rating, isolation voltage, feature equivalence (e.g., SCP), mounting type, package, size/dimensions, and compliance with environmental standards (RoHS, REACH). Only those meeting or exceeding all these criteria are listed as true substitutes.

Parameter Comparison

Engineering Selection Recommendations

The RTS-153.3/HP is classified as obsolete while the R2S-153.3/HP is listed as active. Both modules maintain equivalent key parameters for electrical performance, feature set, and compliance, including RoHS and REACH status. Both parts offer the same output characteristics, isolation, and mounting method. The substitute R2S-153.3/HP provides a wider specified operating temperature range. Dimensional compatibility is dependent on width variances as specified. All listed compliance and certifications are equivalent for both modules.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for substituting RTS-153.3/HP in an existing design?
A1: Critical parameters include input voltage range, output voltage and current, power rating, isolation voltage, number of outputs, mounting type, package, and environmental compliance (RoHS, REACH).

Q2: Are the RTS-153.3/HP and R2S-153.3/HP interchangeable in all socket and PCB layouts?
A2: Both use an 8-SMD Module, 5 Leads package and share most dimensions, but the substitute part has a wider body (10.7mm vs 9.3mm). Review PCB land pattern compatibility based on published size specifications.

Q3: Do both the RTS-153.3/HP and R2S-153.3/HP offer identical electrical and protection features?
A3: Both provide one isolated 3.3V output at 2W with short-circuit protection (SCP) and 3kV isolation.

Q4: Is there any difference in the environmental or compliance status between these two parts?
A4: Both are ROHS3 compliant with MSL 1 (Unlimited) and are REACH unaffected.

Q5: Are there any improvements or differences in operating temperature?
A5: The R2S-153.3/HP has an expanded operating temperature range (-40°C ~ 100°C compared to -40°C ~ 85°C). All other parameters are equivalent.
