Key Parameters

Substitute Part Grouping Explanation

Substitution of the ND3FC10B is based on strict equivalence of the following critical parameters:

• Circuit configuration: BCD Complement encoding
• Number of positions: 10-position selection
• Electrical ratings: 100mA at 5VDC
• Actuator mechanism: Rotary for tool actuation
• Mounting technology: Surface mount with gull wing termination
• Contact system: Beryllium copper with gold plating
• Environmental compliance: RoHS3 compliance

The substitute part FD02FC10P-S from NKK Switches maintains these core electrical and mechanical specifications, ensuring functional compatibility in applications currently using the ND3FC10B.

Parameter Comparison

Engineering Selection Recommendations

The FD02FC10P-S is the recommended substitute for the ND3FC10B based on the following criteria:

• Both parts are manufactured by NKK Switches, ensuring consistent design philosophy and quality standards
• Electrical specifications are identical: 10-position BCD complement configuration, 100mA at 5VDC
• The FD02FC10P-S maintains active product status, providing assured long-term availability compared to the Last Time Buy status of the ND3FC10B
• Both parts comply with RoHS3 requirements, supporting current environmental regulations
• Surface mount technology and gull wing termination are consistent across both parts

Frequently Asked Questions (FAQ)

Q: Can the FD02FC10P-S directly replace the ND3FC10B in existing designs?

A: Yes. Both parts share identical electrical ratings (100mA, 5VDC), circuit configuration (BCD Complement), position count (10), and surface mount termination style. The parts are functionally equivalent for applications currently using the ND3FC10B.

Q: Why is the ND3FC10B listed as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production. The FD02FC10P-S, with Active status, represents the current production alternative from NKK Switches for this switch category.

Q: Are there differences in actuator design between these parts?

A: The ND3FC10B specifies "Rotary for Tool" actuator type, while the FD02FC10P-S is listed as "Position Actuator." Both are rotary surface mount switches designed for tool-based actuation in 10-position configurations. Mechanical compatibility should be confirmed through physical evaluation if actuator geometry is critical to the application.

Q: Do both parts meet current compliance requirements?

A: Yes. Both the ND3FC10B and FD02FC10P-S are RoHS3 compliant, meeting current environmental and regulatory standards for electronic components.

Q: What is the inventory status for these parts?

A: The ND3FC10B has 736 pieces in stock (Last Time Buy status). The FD02FC10P-S has 1135 pieces in stock with Active product status, providing greater availability for ongoing production needs.
