RSS-0509/P-R Equivalent & Substitute Parts Reference

Part Overview

The Recom Power RSS-0509/P-R is an isolated DC DC converter module providing a single 9V output at up to 111mA with a 4.5V to 5.5V input range and 1 W output power. This module operates across -40°C to 85°C, features short-circuit protection, and is rated for 1 kV isolation. The RSS-0509/P-R is classified as obsolete, which makes identifying compatible substitute parts essential to ensure design continuity, sourcing flexibility, and maintainability of commercial electronic systems requiring this DC DC converter.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by matching the following key parameters: input voltage range (4.5V - 5.5V), output voltage (9V), maximum output current (111mA), output power (1 W), voltage isolation (1 kV), number of outputs (1), mounting type (surface mount), package/case (8-SMD Module, 5 Leads), size/dimensions, operating temperature range, efficiency (78%), ITE (Commercial) application, RoHS compliance, and MSL rating. These parameters ensure functional, electrical, and mechanical compatibility within the same category. The RSS-0509/P-R and R1S-0509/P-R meet all matched criteria based on provided data.

Parameter Comparison

Engineering Selection Recommendations

Select alternative parts with the same RoHS status (ROHS3 Compliant), MSL level (1, Unlimited), and compliance certifications to match supply chain and environmental requirements. The substitute R1S-0509/P-R is active and directly matches the electrical, thermal, mechanical, and compliance parameters provided for the RSS-0509/P-R.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for an RSS-0509/P-R substitute?
A1: Input voltage range, output voltage, output current, power rating, voltage isolation, number of outputs, mounting type, package/case, efficiency, operating temperature, compliance (RoHS, MSL), and application must match for direct substitution.

Q2: Are package dimensions interchangeable between RSS-0509/P-R and R1S-0509/P-R?
A2: Both parts use an 8-SMD Module, 5 Leads package with similar physical dimensions; any dimensional differences are within the provided ranges.

Q3: What is the difference in product status?
A3: RSS-0509/P-R is obsolete; R1S-0509/P-R is active.

Q4: Do both part numbers carry the same export and environmental compliance?
A4: Both are ROHS3 compliant, MSL 1, and list identical ECCN and HTSUS categories.

Q5: Is the substitute intended for the same application category?
A5: Yes, both are designed for ITE (Commercial) applications as specified.
