Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NDFR10H is determined by strict alignment with the following critical parameters:

• Circuit encoding: BCD
• Position count: 10 positions
• Electrical ratings: 100mA at 5VDC
• Actuator mechanism: Rotary for tool actuation
• Mounting configuration: Through hole, right angle orientation
• Termination: PC pin style
• Contact system: Beryllium copper with gold finish

The substitute part FD01FR10H-S is classified as an equivalent alternative based on matching circuit type (BCD), position count (10), current rating (100mA), and voltage rating (5VDC). This part is currently in Active product status, providing ongoing availability for applications requiring NDFR10H functionality.

Parameter Comparison

Engineering Selection Recommendations

The NDFR10H is classified as Last Time Buy, indicating end-of-life status with no future production planned. For new designs or ongoing production requiring equivalent functionality, the FD01FR10H-S is the appropriate selection. This substitute maintains identical electrical specifications (BCD encoding, 10-position configuration, 100mA/5VDC ratings) and is manufactured by the same supplier (NKK Switches), ensuring functional compatibility.

The FD01FR10H-S carries Active product status, confirming current manufacturing availability and supply chain continuity. Both parts comply with ROHS3 requirements, supporting regulatory compliance in applications subject to RoHS directives.

For existing systems currently using NDFR10H, the FD01FR10H-S provides a direct functional replacement. Verification of mechanical fit and PCB layout compatibility is necessary prior to implementation, as detailed specifications regarding mounting dimensions and termination geometry were not provided for the substitute part.

Frequently Asked Questions (FAQ)

Q: Can FD01FR10H-S be used as a direct replacement for NDFR10H in existing designs?

A: FD01FR10H-S matches the critical electrical parameters (BCD circuit, 10 positions, 100mA, 5VDC) required for functional equivalence. Physical compatibility must be verified through mechanical drawings and PCB layout assessment, as packaging and mounting dimension details were not provided for the substitute part.

Q: Why is NDFR10H designated as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production of this component. Existing inventory may be available through authorized distributors, but no future manufacturing is planned. Transition to active alternatives such as FD01FR10H-S is recommended for long-term supply security.

Q: What parameters determine substitution eligibility for BCD rotary switches?

A: Substitution is valid when the following parameters match: circuit type (BCD), position count (10), current rating (100mA), voltage rating (5VDC), actuator type (rotary for tool), and termination style (PC pin). Deviations in any of these parameters may result in functional incompatibility.

Q: Are there compliance differences between NDFR10H and FD01FR10H-S?

A: Both parts are manufactured by NKK Switches and comply with ROHS3 requirements. Specific compliance certifications for FD01FR10H-S (such as REACH status, ECCN, or HTSUS classification) were not provided in the available data.

Q: What should be verified before implementing FD01FR10H-S as a replacement?

A: Mechanical fit verification is essential, including mounting hole alignment, height above PCB, and actuator clearance. Electrical performance under the application's specific load conditions should be confirmed. PCB layout modifications may be necessary if packaging dimensions differ between the original and substitute parts.
