Equivalent & Substitute Parts for RO-0509S DC DC Converter
Part Overview
The Recom Power RO-0509S is an isolated module DC DC converter designed for ITE (Commercial) applications, delivering a single regulated 9V output at up to 111mA from a 4.5V–5.5V input. This model is currently active and available in substantial inventory. Sourcing alternative models may be necessary to address lead times, multi-vendor sourcing, or supply chain flexibility. Substitutions are considered only when all relevant electrical and mechanical parameters align strictly with the original component specification.

Substitute Part Grouping Explanation
Substitution logic is strictly determined by identical or compatible values for the following key parameters: input voltage range, output voltage, maximum output current, power rating, isolation voltage, mounting type, package style, dimensions, and environmental compliance (RoHS/REACH). All substitute components included meet these core criteria within the DC DC converter (isolated module, 1W, 1 output) product category.

Moisture Sensitivity Level for both is 1 (Unlimited), indicating suitability for standard assembly and handling. B0509S-1WR3 includes CE and cURus approvals; this information is explicitly provided and may be relevant for regulated environments. Selection depends exclusively on the matched key parameters and compliance status as outlined.
Frequently Asked Questions (FAQ)
Q1: What are the critical criteria for substituting DC DC converters in this category?
A1: Substitutions require identical input and output voltage ranges, output current, isolation voltage, mounting type, package format, dimensions, and compliance with environmental regulations (RoHS, REACH).
Q2: Are both RO-0509S and B0509S-1WR3 compatible regarding footprint and mounting?
A2: Both devices use the 4-SIP module package with through-hole mounting and closely matching dimensions as stated in the specifications.
Q3: Do product status and inventory affect substitution decisions?
A3: Product status is "Active" for both parts, meaning they are standard, catalogued products with available inventory based on the provided details.
Q4: Is there any difference in compliance or regulatory certifications between the two options?
A4: Both parts are RoHS and REACH compliant. B0509S-1WR3 also includes CE and cURus approvals per the provided information.
Q5: Can the higher isolation voltage and extended operating temperature of B0509S-1WR3 impact compatibility?
A5: Only explicit parameter matches are used for substitution. Variations, such as higher isolation voltage and extended operating temperature, are listed but not used unless required by the substitution logic defined above.
Q6: Are there any mechanical differences affecting interchangeability?
A6: Physical dimensions and mounting style for both components are matched as per the input data for direct substitution consideration.
