Equivalent & Substitute Parts for PCN2-S5-S5-S
Part Overview
The PCN2-S5-S5-S from CUI Inc. is an active DC-DC isolated module converter designed for ITE (Commercial) applications. It provides a single regulated output of 5V at up to 400mA, with an input voltage range of 4.5V to 5.5V and a total output power of 2W. Substitute models are necessary in cases of inventory management, supply chain constraints, or where alternative brand sourcing is required. Substitutes must match the electrical and mechanical parameters to ensure functional equivalence.

The efficiency and output parameters are also compatible within the allowed range as provided.
Frequently Asked Questions (FAQ)
Q: What core electrical parameters must match for a valid substitute?
A: Allowed substitutes require identical input voltage range, output voltage, maximum output current, output power rating, and voltage isolation rating.
Q: Is package and mechanical compatibility ensured between PCN2-S5-S5-S and RI-0505S?
A: Both use SIP modules and through-hole mounting; however, the mechanical dimensions and the pin count (6-SIP vs 4-SIP) must be verified for layout fit as specified in the provided parameters.
Q: Do both PCN2-S5-S5-S and RI-0505S comply with RoHS and REACH requirements?
A: Both are listed as RoHS compliant and REACH unaffected, supporting equivalence for regulatory compliance.
Q: Do environment ratings (MSL, ECCN, HTSUS) affect substitutability?
A: Both parts share Moisture Sensitivity Level 1, ECCN EAR99, and HTSUS 8504.40.9580, ensuring compatibility in standard inventory management and export practices.
Q: Is operating temperature range a key factor in substitution?
A: The substitute operates from -40°C to 85°C, while the main part operates up to 100°C. This parameter should be considered based solely on application environment requirements as provided.
