Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NDKC16P is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: Hexadecimal Complement (16-position logic)
• Mounting interface: Through Hole with 0.100" (2.54mm) pitch
• Termination style: PC Pin
• Contact material and finish: Beryllium Copper with Gold plating
• Mechanical life rating: Minimum 20,000 steps

Electrical Operating Range:

• Voltage rating must accommodate 5VDC operation
• Current capacity must support 100mA minimum

Environmental Compliance:

• RoHS3 compliance or equivalent regulatory status
• Moisture Sensitivity Level 1 (Unlimited)

The substitute parts identified meet these core criteria while maintaining functional equivalence in hexadecimal complement switching applications.

Engineering Selection Recommendations

FD01KR16P-S (NKK Switches): This part is the manufacturer-recommended equivalent from NKK Switches. As an active product from the same manufacturer, it provides the most direct substitution path for NDKC16P applications. The part maintains the same hexadecimal complement circuit configuration and 16-position through-hole interface. Selection of this part eliminates design re-qualification risk and maintains supply chain continuity within the NKK Switches product family.

1-1825013-2 (TE Connectivity ALCOSWITCH): This part provides functional equivalence as a hexadecimal complement 16-position rotary DIP switch with through-hole mounting and 0.100" pitch. The higher voltage rating (20VAC/DC) and extended operating temperature range (-30°C ~ 85°C) offer broader application flexibility. However, the electrical life rating (10,000 steps) is lower than the NDKC16P specification. This part is suitable for applications where the NDKC16P voltage and temperature margins are not fully utilized. The actuator type (rotary for tool) differs from the shaft actuator of the main part, requiring mechanical interface verification.

Both substitute parts carry active product status, ensuring ongoing availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the FD01KR16P-S directly replace the NDKC16P without PCB modifications? A: The FD01KR16P-S maintains the same hexadecimal complement circuit, 16-position configuration, and through-hole pitch (0.100"). Direct PCB compatibility is supported. Verify actuator shaft dimensions and actuation force requirements for your specific application interface.

Q: What are the key differences between the TE Connectivity 1-1825013-2 and the NDKC16P? A: The 1-1825013-2 operates at higher voltage (20VAC/DC vs. 5VDC) and has a lower electrical life rating (10,000 steps vs. 20,000 cycles). The actuator type is rotary for tool rather than rotary with shaft. These differences require application-level compatibility assessment before selection.

Q: Is the 1-1825013-2 suitable for 5VDC applications? A: Yes. The 20VAC/DC voltage rating encompasses 5VDC operation. However, verify that the actuator interface (rotary for tool) is compatible with your mechanical actuation method, as it differs from the shaft actuator design of the NDKC16P.

Q: What is the pitch specification, and why does it matter? A: Pitch refers to the center-to-center spacing of the through-hole pins (0.100" or 2.54mm). All identified parts maintain this standard pitch, ensuring PCB footprint compatibility without layout redesign.

Q: Are both substitute parts RoHS compliant? A: The FD01KR16P-S compliance status is not specified in available data. The 1-1825013-2 RoHS status is listed as not applicable. The NDKC16P is ROHS3 compliant. Verify regulatory compliance requirements for your application and request detailed compliance documentation from manufacturers as needed.

Q: What is the difference between mechanical life and electrical life? A: Mechanical life (measured in steps) indicates the number of physical actuations the switch can withstand. Electrical life (measured in cycles) indicates the number of electrical switching operations. Both parameters define component durability under different stress conditions.
