Substitute Part Grouping Explanation

Substitution eligibility for the ND3KC10P is determined by the following critical parameters:

• Circuit Configuration: BCD Complement encoding for 10-position selection
• Electrical Ratings: 100mA current capacity at 5VDC operating voltage
• Actuator Mechanism: Rotary shaft actuator with raised actuation level
• Mounting and Termination: Surface mount with gull wing termination and 0.100" (2.54mm) pitch
• Contact System: Beryllium copper contacts with gold finish for reliable signal transmission
• Environmental Compliance: ROHS3 compliance and REACH unaffected status for regulatory alignment
• Mechanical Durability: 20,000 steps mechanical and electrical life rating

The substitute part FD02KR10P-S from NKK Switches maintains functional equivalence through matching circuit type, electrical ratings, and actuator configuration, enabling direct replacement in applications requiring BCD complement rotary DIP switch functionality.
