Key Parameters

Substitute Part Grouping Explanation

Substitution of the NDKC16H is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Hexadecimal complement 16-position switching
• Electrical Ratings: 100mA current capacity at 5VDC
• Mechanical Interface: Rotary shaft actuator with through-hole, right-angle mounting
• Contact System: Beryllium copper with gold plating for reliable low-voltage switching
• Pitch and Spacing: 0.100" (2.54mm) standard pitch for PCB compatibility
• Environmental Compliance: RoHS3 compliance and MSL 1 rating

The FD01FC16H-S from NKK Switches meets these core substitution criteria, maintaining functional and electrical equivalence for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The FD01FC16H-S is the primary substitute for the NDKC16H. Both components are manufactured by NKK Switches and maintain identical electrical and mechanical specifications across all critical parameters. The FD01FC16H-S carries Active product status, ensuring continued availability and supply chain support, whereas the NDKC16H is in Last Time Buy status. For new designs or production continuity, the FD01FC16H-S is the appropriate selection. Both parts maintain RoHS3 compliance and are suitable for applications within the specified operating temperature range of -25°C to 75°C.

Frequently Asked Questions (FAQ)

Q: Can the FD01FC16H-S directly replace the NDKC16H in existing designs? A: Yes. Both parts share identical electrical ratings (100mA, 5VDC), circuit configuration (hexadecimal complement, 16 positions), mechanical interface (rotary shaft, through-hole right-angle mounting), and pitch (0.100"). No PCB redesign is required.

Q: What is the primary reason to transition from NDKC16H to FD01FC16H-S? A: The NDKC16H is in Last Time Buy status, indicating end-of-life production. The FD01FC16H-S maintains Active status, ensuring long-term availability and supply reliability.

Q: Are there any compliance differences between these parts? A: Both parts are RoHS3 compliant with MSL 1 rating. No compliance barriers exist for substitution.

Q: What are the key parameters that must match for substitution? A: Circuit type (hexadecimal complement), position count (16), current and voltage ratings (100mA, 5VDC), actuator type (rotary with shaft), mounting configuration (through-hole right-angle), and pitch (0.100") must remain constant.

Q: Is the FD01FC16H-S available in the same packaging as the NDKC16H? A: Both parts use standard through-hole packaging with identical mechanical footprints and pitch specifications, ensuring direct PCB compatibility.
