ND3FC16B Equivalent & Substitute Parts

Part Overview

The ND3FC16B is a surface mount rotary DIP switch manufactured by NKK Switches, designed for hexadecimal complement applications requiring 16-position selection. This component operates at 5VDC with a 100mA current rating and features a tool-actuated rotary mechanism with flush, recessed actuation. The ND3FC16B is currently in Last Time Buy status, indicating discontinued production. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for ongoing production and field service requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ND3FC16B is determined by strict equivalence across the following critical parameters:

• Hexadecimal complement circuit configuration with 16-position selection capability
• 5VDC voltage rating and 100mA current rating
• Rotary tool-actuated mechanism with flush, recessed actuation
• Surface mount package with gull wing termination
• Beryllium copper contacts with gold finish
• 0.100" (2.54mm) pitch spacing
• Operating temperature range of -25°C to 85°C
• Mechanical and electrical life rating of 20,000 steps minimum

The substitute part FD02FC16P-S meets these critical parameters and is manufactured by the same supplier, ensuring functional and mechanical compatibility within the specified electrical and environmental constraints.

Parameter Comparison

Engineering Selection Recommendations

The FD02FC16P-S is the designated substitute for the ND3FC16B based on functional equivalence in circuit configuration, electrical ratings, and mechanical interface. The ND3FC16B is in Last Time Buy status, making the FD02FC16P-S the appropriate selection for new designs and ongoing production requirements. The substitute part is manufactured by NKK Switches and maintains Active product status, ensuring continued availability and supply chain stability. Both parts are manufactured by the same supplier, reducing qualification risk for substitution in existing applications.

Frequently Asked Questions (FAQ)

Q: Can the FD02FC16P-S directly replace the ND3FC16B in existing designs?

A: The FD02FC16P-S meets the critical electrical and mechanical parameters specified for the ND3FC16B, including 16-position hexadecimal complement configuration, 5VDC/100mA ratings, surface mount package, and tool-actuated rotary mechanism. Substitution is valid within the specified parameter constraints.

Q: What is the difference between the ND3FC16B and FD02FC16P-S?

A: Both parts are 16-position hexadecimal complement rotary DIP switches rated for 5VDC and 100mA operation. The primary difference is product status: the ND3FC16B is Last Time Buy (discontinued), while the FD02FC16P-S is Active (current production). The ND3FC16B specifies beryllium copper contacts with gold finish and gull wing termination; equivalent specifications for the FD02FC16P-S are not provided in available data.

Q: Are there any compliance or certification differences?

A: The ND3FC16B is ROHS3 compliant with MSL 1 (Unlimited) and REACH Unaffected status. Compliance certifications for the FD02FC16P-S are not specified in the provided data and should be verified through the manufacturer's current documentation.

Q: What packaging options are available for the substitute part?

A: Packaging information for the FD02FC16P-S is not specified in the provided data. Contact the manufacturer for current packaging and availability options.

Q: Should I qualify the substitute part before implementation?

A: Substitution decisions should be based on the parameter equivalence documented in this reference. Verification of unspecified parameters (contact material, contact finish, termination style, and compliance certifications) for the FD02FC16P-S should be obtained from NKK Switches technical documentation.
