Substitute Part Grouping Explanation

The substitute part 5173280-3 is a direct functional equivalent to the main part 173280-3. Substitution is valid based on the following critical parameters that remain identical across both parts:

• Connector Configuration: Both are 50 Position D-Type Board to Board Cap connectors with male pins
• Electrical Specifications: Identical current rating (1A), voltage rating (100V), and contact finish (Gold, 8.00µin)
• Mechanical Specifications: Identical pitch (0.050), row spacing (0.100), mounting type (Through Hole), and termination method (Solder)
• Environmental Ratings: Identical operating temperature range (-55°C ~ 105°C), flammability rating (UL94 V-0), and moisture sensitivity level (MSL 1)
• Series Designation: Both belong to the AMPLIMITE .050 I series

The primary distinction between the parts is product status and compliance certification. The substitute part 5173280-3 is active and RoHS3 compliant, whereas the main part 173280-3 is obsolete and RoHS non-compliant.
