Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NDFC16H is determined by strict alignment with the following critical parameters:

• Circuit Configuration: Hexadecimal complement 16-position switching logic
• Electrical Ratings: 100mA current capacity and 5VDC voltage specification
• Actuator Mechanism: Rotary tool-actuated design with flush, recessed actuator level
• Mounting Architecture: Through-hole, right-angle orientation with PC pin termination
• Contact System: Beryllium copper contacts with gold plating for reliability
• Physical Dimensions: 0.100" pitch and 0.312" height above board for PCB compatibility
• Environmental Compliance: ROHS3 compliance and MSL Level 1 rating

The substitute part FD01FC16H-S from NKK Switches maintains functional equivalence through identical circuit topology, electrical ratings, and actuator specifications, ensuring direct replacement capability in existing applications.

Parameter Comparison

Engineering Selection Recommendations

The FD01FC16H-S represents the primary substitute for the NDFC16H based on product lifecycle status and supply continuity. The NDFC16H is designated Last Time Buy, indicating end-of-life status with finite inventory. The FD01FC16H-S maintains Active product status with current manufacturing support from NKK Switches, providing assured long-term availability for new designs and replenishment orders.

Both components satisfy ROHS3 compliance requirements and maintain identical electrical and mechanical specifications, enabling direct substitution without circuit redesign or PCB layout modification. Selection between these parts should prioritize the FD01FC16H-S for new applications and ongoing production requirements to ensure supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the FD01FC16H-S directly replace the NDFC16H without PCB modifications?

A: Yes. Both components share identical mounting type (through-hole, right-angle), pitch (0.100"), height above board (0.312"), and termination style (PC pin). No PCB layout changes are required for substitution.

Q: Are the electrical characteristics identical between these parts?

A: Yes. Both components operate at 100mA current rating and 5VDC voltage specification with hexadecimal complement 16-position circuit configuration. Electrical performance is equivalent.

Q: What is the significance of the NDFC16H Last Time Buy status?

A: Last Time Buy designation indicates NKK Switches has discontinued production of the NDFC16H. Current inventory of 4,782 pieces represents the final available stock. The FD01FC16H-S is the recommended transition path for continued supply access.

Q: Do both parts meet the same environmental and compliance standards?

A: Both components are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating. Operating temperature range is -25°C to 75°C for both parts.

Q: What is the mechanical and electrical life expectancy for these components?

A: Both the NDFC16H and FD01FC16H-S are rated for 20,000 mechanical steps and 20,000 electrical cycles, providing equivalent operational durability.
