RSS-0509/HP Equivalent & Substitute Parts Reference

Part Overview

The Recom Power RSS-0509/HP is an isolated DC-DC converter module delivering a single 9V output at up to 111mA from a 4.5V–5.5V input. Designed for ITE (Commercial) and Medical applications, its 1W power rating and 3kV isolation make it suitable for environments requiring robust performance and safety features. The RSS-0509/HP is classified as Obsolete, necessitating identification of direct substitutes to maintain product availability and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection for DC-DC converter modules is strictly determined by matching all critical parameters including input voltage range, output voltage and current, isolation voltage, power rating, mounting type, package/case dimensions, operating temperature, regulatory compliance (e.g., RoHS, REACH), and product status. Only parts meeting these criteria are considered valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

The RSS-0509/HP has an Obsolete product status. Substitute selection must prioritize components with equivalent electrical and mechanical characteristics, confirmed regulatory compliance (RoHS3 Compliant, REACH Unaffected), and compatible packaging and mounting. R1S-0509/HP retains all compliance statuses, delivers matching output, input, and isolation parameters, and maintains the same mounting and package type. Series and product status changes must be noted for lifecycle planning.

Frequently Asked Questions (FAQ)

Q1: Which key parameters must match for substituting DC-DC converter modules in this category?
A1: Parameters required for substitution include input voltage range, output voltage, output current, isolation voltage, power rating, number of outputs, mounting type, package and size/dimensions, operating temperature range, regulatory compliance, and mechanical compatibility.

Q2: Can R1S-0509/HP be directly substituted for RSS-0509/HP without modification?
A2: R1S-0509/HP matches the RSS-0509/HP on all input, output, isolation, package, compliance, and mounting parameters. Dimensions differ slightly and should be verified for mechanical fit in the application.

Q3: Is there any change in product series or lifecycle status that affects substitution?
A3: The substitute, R1S-0509/HP, is from the ECONOLINE R1S (1W) series and is Active, whereas the main part RSS-0509/HP is Obsolete and from the ECONOLINE RSS (1W) series.

Q4: Are compliance and environmental standards matched between the substitute parts?
A4: Both RSS-0509/HP and R1S-0509/HP are ROHS3 Compliant, REACH Unaffected, and share identical ECCN and HTSUS classifications.

Q5: Are there differences in operating temperature or package dimensions to consider?
A5: R1S-0509/HP offers a broader operating temperature range (-40°C ~ 100°C) and slightly different package dimensions (0.50" L x 0.42" W x 0.28" H). Confirming space and thermal requirements in the application is necessary.
