Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped strictly based on matching or exceeding the listed key parameters:

• Output voltage of 15V
• Input voltage range of 66V to 160V
• Isolation voltage of 3 kV
• Single output configuration
• Package type: 8-DIP Module, Through Hole
• Standard Number: 62368-1
• RoHS3 compliance
• Applications for ITE (Commercial) and Railway

Only substitutes meeting these exact criteria and providing equal or higher output current may be considered for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

The RCQ50110S15 is obsolete, while the RCQ75110S15 is in active production and shares all primary certifications, compliances, and standard numbers. Both parts are ROHS3 compliant and have identical mechanical dimensions and operational envelope, including isolation rating and input range. Therefore, selection of RCQ75110S15 as a substitute is supported on the basis of product status and maintained regulatory compliance.
