Key Parameters

Substitute Part Grouping Explanation

Substitution for the AT-23256-9 is determined by the following critical parameters:

• Connector Interface Conversion: D-Sub 9-pin male input and RJ45 (8p8c) female jack output
• Mechanical Compatibility: Physical form factor and pin configuration
• Electrical Specifications: Signal integrity for serial communication applications
• Compliance Requirements: RoHS and REACH certifications

The AT-23066 qualifies as a direct substitute based on identical connector interface specifications and mechanical compatibility. The primary distinction is product status and compliance level.
