NDKC10P Equivalent & Substitute Parts

Part Overview

The NDKC10P is a 10-position rotary DIP switch manufactured by NKK Switches, designed for through-hole PCB mounting applications requiring BCD complement encoding. This component operates at 5VDC with a 100mA current rating and features a rotary shaft actuator with raised actuation level. The part is currently in Last Time Buy status, indicating discontinued production with limited remaining inventory. Identifying equivalent substitute parts is necessary to ensure design continuity and long-term component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NDKC10P is determined by strict equivalence across the following critical parameters:

• Circuit encoding: BCD Complement configuration
• Position count: 10-position rotary selection
• Electrical ratings: 100mA at 5VDC
• Actuator mechanism: Rotary with shaft actuation
• Mounting interface: Through-hole PCB termination
• Physical footprint: 0.100" pitch and compatible height profile
• Contact system: Beryllium copper with gold finish for signal integrity
• Environmental compliance: ROHS3 and REACH status

The FD01KR10P-S qualifies as a direct substitute based on matching circuit type, position count, current and voltage ratings, and rotary actuator configuration. This part maintains functional and electrical equivalence while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The FD01KR10P-S is the qualified substitute for the NDKC10P based on functional and electrical parameter equivalence. Selection between these parts should prioritize the FD01KR10P-S for new designs and production runs due to its Active product status, which ensures long-term availability and supply chain stability. The NDKC10P remains suitable for field replacements and maintenance applications where existing inventory is available, though procurement should transition to the FD01KR10P-S to avoid Last Time Buy constraints.

Both parts maintain ROHS3 compliance and are manufactured by the same supplier, ensuring consistent quality and performance characteristics. The electrical and mechanical specifications are equivalent across all critical parameters, supporting direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the FD01KR10P-S replace the NDKC10P in existing designs?

A: Yes. Both parts share identical circuit encoding (BCD Complement), position count (10), electrical ratings (100mA at 5VDC), actuator type (rotary with shaft), and mounting interface (through-hole). Direct substitution is supported without PCB or firmware modifications.

Q: Why is the NDKC10P listed as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production. Existing inventory is limited to 621 pieces. The FD01KR10P-S provides continuity for applications requiring this component type.

Q: Are there mechanical compatibility concerns between these parts?

A: Both parts use 0.100" (2.54mm) pitch through-hole termination and are designed for standard DIP switch footprints. Mechanical compatibility is maintained across PCB mounting and actuator engagement.

Q: What compliance certifications apply to both parts?

A: Both the NDKC10P and FD01KR10P-S are ROHS3 compliant. The NDKC10P is REACH Unaffected. Compliance documentation should be verified with the manufacturer for specific application requirements.

Q: Is the FD01KR10P-S suitable for the same operating temperature range?

A: The NDKC10P operates across -25°C to 75°C. Detailed operating temperature specifications for the FD01KR10P-S should be confirmed with the manufacturer's datasheet to ensure compatibility with your application environment.
