NDFR10P Equivalent & Substitute Parts

Part Overview

The NDFR10P is a DIP rotary switch manufactured by NKK Switches, designed for applications requiring 10-position BCD encoding with a 100mA current rating at 5VDC. This through-hole component features a rotary tool actuator with a flush, recessed design and is sealed for washable applications. The part is currently in Last Time Buy status, indicating discontinued production. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain supply chain reliability for existing applications or new designs requiring compatible functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NDFR10P is determined by the following critical parameters:

• Circuit Configuration: BCD encoding for 10-position output
• Electrical Ratings: 100mA current capacity at 5VDC minimum
• Actuator Mechanism: Rotary tool-actuated design
• Mounting Interface: Through-hole termination with 0.100" (2.54mm) pitch
• Contact System: Beryllium copper with gold finish for reliability and corrosion resistance
• Environmental Sealing: Process-sealed construction for washable applications
• Mechanical Durability: 20,000-step mechanical life and 20,000-cycle electrical life

The substitute part FD01FR10P-S from NKK Switches meets the functional requirements of BCD 10-position rotary switching at 100mA/5VDC with compatible through-hole mounting. Both parts originate from the same manufacturer, ensuring design consistency and performance alignment.

Parameter Comparison

Engineering Selection Recommendations

The NDFR10P is designated Last Time Buy, indicating end-of-life status. For new designs or long-term production requirements, FD01FR10P-S is the recommended substitute. This part maintains active product status with NKK Switches, ensuring continued availability and manufacturer support.

Both parts are manufactured by NKK Switches and share identical electrical specifications (BCD 10-position, 100mA, 5VDC). The FD01FR10P-S provides functional equivalence with the advantage of active production status and ongoing supply chain support.

Selection between these parts should be based on:

• Existing Inventory: NDFR10P stock (1137 units) is available for immediate use in current production runs
• Long-Term Availability: FD01FR10P-S is recommended for new designs and future production planning
• Compliance Requirements: Both parts meet ROHS3 compliance and carry MSL 1 rating

Frequently Asked Questions (FAQ)

Q: Can FD01FR10P-S directly replace NDFR10P in existing designs?

A: Yes. Both parts share identical BCD 10-position encoding, 100mA current rating, 5VDC voltage specification, and through-hole mounting with 0.100" pitch. Electrical and mechanical compatibility is confirmed.

Q: What is the difference between the actuator types listed?

A: NDFR10P specifies "Rotary for Tool" actuator, while FD01FR10P-S lists "Position Actuator." Both designations refer to rotary tool-actuated mechanisms for 10-position selection. The functional operation and interface are equivalent.

Q: Why is NDFR10P marked Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued this part number. Existing inventory is available for purchase, but no future production is planned. FD01FR10P-S is the active replacement part.

Q: Are there any packaging or MSL differences?

A: NDFR10P is supplied in Tray packaging with MSL 1 (Unlimited). FD01FR10P-S packaging information is not specified in available data. Verify packaging requirements with the supplier for your specific application needs.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no special storage or handling requirements. REACH status is Unaffected for NDFR10P.
