Recom Power RSS-053.3/P Equivalent & Substitute Parts Reference

Part Overview

The Recom Power RSS-053.3/P is a 1W isolated DC-DC converter module designed for ITE (commercial) applications. It features a single 3.3V output at up to 303mA from a 4.5V to 5.5V input, with an isolation rating of 1kV and surface mount packaging. The part is obsolete and has restricted long-term availability, necessitating the evaluation of directly compatible substitute models to ensure continuity in engineering designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are identified based strictly on exact matches for electrical and mechanical key parameters. Parameters considered for substitution include input voltage range, output voltage and current, power rating, isolation voltage, mounting type, package, compliance, and intended application. Substitute parts listed match all these criteria as provided in the input data.

Key substitution parameters:

• Input and output voltage ratings (4.5V – 5.5V input, 3.3V output)
• Output current (303mA)
• Power rating (1W)
• Isolation voltage (1kV)
• Package type (8-SMD Module, 5 Leads) and surface mount mounting
• Compliance (RoHS, REACH, MSL)
• Application suitability
• Product features and mechanical dimensions within listed tolerances

Parameter Comparison

Engineering Selection Recommendations

The RSS-053.3/P is classified as obsolete, while the R1S-053.3/P is active and directly matches on key technical parameters including output voltage and current, power rating, isolation voltage, mounting method, and compliance (ROHS3, MSL 1, REACH Unaffected). The substitute R1S-053.3/P also satisfies the same application profile and features. Only product status and compliance should be referenced for selection as both modules meet all listed technical and regulatory requirements.

Frequently Asked Questions (FAQ)

Q1: What parameters must match to select an equivalent DC-DC converter in this category?
A1: Input voltage range, output voltage and current, power rating, isolation voltage, application, package type, mounting style, and regulatory compliance are mandatory.

Q2: Are the RSS-053.3/P and R1S-053.3/P mechanically and electrically compatible?
A2: Both parts share the same electrical ratings and mounting type. Package forms are specified as 8-SMD Module, 5 Leads, and dimensions are provided for direct comparison.

Q3: Does RoHS and REACH compliance affect substitution in this case?
A3: Both RSS-053.3/P and R1S-053.3/P are ROHS3 Compliant and REACH Unaffected, which fulfills standard compliance requirements for substitution.

Q4: How should product status be considered for substituting the DC-DC converter?
A4: The RSS-053.3/P is obsolete, making it necessary to select the active R1S-053.3/P for new or ongoing designs.

Q5: Are there any differences in operational temperature range?
A5: The R1S-053.3/P supports an extended operating temperature range as listed (-40°C ~ 100°C) compared to RSS-053.3/P (-40°C ~ 85°C).

Q6: Is there a difference in moisture sensitivity level (MSL) for storage or handling?
A6: Both models are rated at MSL 1 (Unlimited), so there is no difference for handling and storage requirements.
