RTS-0505 Equivalent & Substitute Parts Reference

Part Overview

The RTS-0505 by Recom Power is an isolated DC-DC converter, designed for single-output 5V applications in ITE (Commercial) environments. Rated at 2W output with short circuit protection (SCP), it features a 1kV isolation voltage and operates in a wide temperature range. As this part is now designated "Obsolete," sourcing direct replacements or substitutes with matching electrical and mechanical characteristics is essential to maintain system compatibility and regulatory compliance.

Engineering Selection Recommendations

The RTS-0505 is verified as obsolete. The R2S-0505 shares all core certifications including ROHS3 and REACH status, identical output and input ratings, regulatory compliance, and mounting type. Any dimensional or packaging differences must be compared to system-level mechanical constraints in the design.

Frequently Asked Questions (FAQ)

Q1: What parameters are required for a substitute for RTS-0505?
A1: Substitute parts must match input/output voltage and current, isolation voltage, power rating, efficiency, mounting type, and compliance statuses.

Q2: Are there any mechanical differences between RTS-0505 and R2S-0505?
A2: Both use 8-SMD Module, 5 Leads packages. The width differs: RTS-0505 is 0.37" while R2S-0505 is 0.42". System compatibility should be verified based on these dimensions.

Q3: Is the R2S-0505 ROHS3 compliant and suitable for REACH-regulated markets?
A3: Yes, R2S-0505 is ROHS3 compliant and REACH unaffected, matching RTS-0505 certifications.

Q4: Do both parts support surface mount assembly?
A4: Yes, both RTS-0505 and R2S-0505 are specified as Surface Mount components.

Q5: What is the operating temperature range difference?
A5: RTS-0505 supports -40°C to 85°C, R2S-0505 supports -40°C to 100°C. Both ranges encompass typical commercial operation requirements.
