Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ND3KC10B is determined by the following critical parameters:

• Circuit Configuration: BCD Complement encoding
• Position Count: 10-position selection capability
• Electrical Ratings: 100mA at 5VDC minimum
• Actuator Mechanism: Rotary with shaft actuation
• Mounting Technology: Surface mount with gull wing termination
• Contact System: Beryllium copper with gold finish
• Environmental Compliance: ROHS3 compliance and MSL 1 rating

The substitute part FD02KR10P-S from NKK Switches maintains functional equivalence through matching circuit type, position count, current and voltage ratings, and actuator configuration. Both components are manufactured by the same supplier, ensuring design consistency and compatibility within the ND3 series rotary DIP switch family.

Parameter Comparison

Engineering Selection Recommendations

The FD02KR10P-S serves as the active production equivalent for the ND3KC10B. Selection of this substitute is supported by:

• Product Status Alignment: The substitute maintains active production status, ensuring long-term availability and supply chain continuity compared to the Last Time Buy status of the original part.
• Functional Equivalence: Both components provide identical BCD complement 10-position switching at 100mA and 5VDC specifications.
• Manufacturer Consistency: Both parts originate from NKK Switches, maintaining design heritage and quality standards within the rotary DIP switch product line.
• Compliance Certification: The main part carries ROHS3 compliance; compliance status for the substitute should be verified during procurement to ensure regulatory alignment with your application requirements.

Frequently Asked Questions (FAQ)

Q: Can the FD02KR10P-S directly replace the ND3KC10B in existing designs?

A: Yes. Both components share identical circuit configuration (BCD Complement), position count (10), electrical ratings (100mA at 5VDC), and surface mount termination. Physical footprint compatibility should be confirmed through datasheet comparison of pitch, height, and gull wing lead dimensions.

Q: What is the primary reason for substitution?

A: The ND3KC10B is in Last Time Buy status, indicating production discontinuation. The FD02KR10P-S is the active production alternative from the same manufacturer, ensuring continued component availability.

Q: Are there any compliance differences between these parts?

A: The ND3KC10B is certified ROHS3 compliant with MSL 1 rating. Compliance documentation for the FD02KR10P-S should be obtained from the manufacturer to confirm equivalent environmental and regulatory certifications.

Q: What parameters must remain constant for substitution?

A: Circuit type (BCD Complement), position count (10), current rating (100mA), voltage rating (5VDC), actuator mechanism (rotary with shaft), and surface mount termination style (gull wing) are non-negotiable substitution criteria.

Q: How should I verify compatibility before design implementation?

A: Obtain complete datasheets for both components and cross-reference mechanical dimensions (pitch, height above board, lead configuration), electrical characteristics (contact resistance, switching speed), and environmental ratings (operating temperature, moisture sensitivity level).
