• Identical connector type: Header, Male Pins and Blades
• Identical number of positions: 28
• Identical pitch: 0.100" (2.54mm)
• Identical number of rows: 4
• Identical mounting type: Board Edge, Through Hole, Right Angle
• Identical contact layout: 24 Signal, 4 Power
• Identical termination method: Solder
• Identical contact finish specification: Gold or Gold, GXT™
• Identical contact finish thickness: 30.0µin (0.76µm)
• Identical color: Black
• Identical material flammability rating: UL94 V-0
• Identical operating temperature range: -20°C ~ 105°C
• Identical moisture sensitivity level: 1 (Unlimited)

The 51722-10402400AALF represents an active product status alternative with enhanced features including board lock and mating guide, while maintaining full mechanical and electrical compatibility.
