DRFC10P Equivalent & Substitute Parts

Part Overview

The DRFC10P is a rotary DIP switch manufactured by NKK Switches, designed for BCD complement applications requiring 10-position selection with 100mA at 5VDC. This component features a through-hole rotary actuator with tool actuation capability and sealed construction for washable applications. The DRFC10P is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The FR01FC10P-S qualifies as a functional substitute for the DRFC10P based on the following critical parameters:

• Circuit Configuration: Both parts implement BCD complement logic with identical 10-position selection capability
• Electrical Ratings: Both support 100mA at 5VDC, meeting the same load requirements
• Mechanical Interface: Both feature rotary tool-actuated design with through-hole mounting and 0.100" (2.54mm) pitch
• Contact System: Both utilize gold-finished copper-based contacts for reliable signal switching
• Termination: Both employ PC pin termination compatible with standard PCB layouts
• Physical Length: Both measure 0.394" (10.00mm) in length

Substitution is valid where the following differences are acceptable to the application:

• Height above board reduction from 0.232" to 0.150"
• Operating temperature upper limit increase from 75°C to 85°C
• Mechanical and electrical life reduction from 20,000 to 10,000 steps
• Body material change from PBT to polyamide (PA) nylon
• Washable feature removal
• Series designation change from DR to FR01

Parameter Comparison

Engineering Selection Recommendations

The FR01FC10P-S is the active production equivalent for the obsolete DRFC10P. Selection of the FR01FC10P-S is appropriate for applications where:

• The reduced height above board (0.150" versus 0.232") is compatible with PCB layout constraints
• Operating temperatures do not exceed 85°C
• Mechanical and electrical cycle life requirements do not exceed 10,000 steps
• RoHS3 compliance is required or beneficial for supply chain management
• Washable feature is not a functional requirement

The FR01FC10P-S maintains electrical and mechanical interface compatibility through identical pitch, termination style, and through-hole mounting. Both parts are manufactured by NKK Switches and share the same REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can FR01FC10P-S directly replace DRFC10P in existing designs?

A: Direct replacement is possible if the application tolerates the specified parameter differences, particularly the reduced height above board and lower cycle life rating. PCB layout verification is required to confirm the 0.082" (2.09mm) height reduction does not create clearance conflicts.

Q: What is the primary reason for substitution?

A: The DRFC10P is obsolete. The FR01FC10P-S is the active production alternative from the same manufacturer with identical electrical ratings and circuit configuration.

Q: Are there packaging differences?

A: The DRFC10P packaging is listed as standard; the FR01FC10P-S is supplied in tube packaging. This affects procurement and handling but does not impact functional performance.

Q: How do the life cycle ratings differ?

A: The DRFC10P is rated for 20,000 mechanical and electrical steps; the FR01FC10P-S is rated for 10,000 steps. Applications requiring extended cycle life should evaluate this difference against actual usage patterns.

Q: Are both parts compliant with environmental regulations?

A: Both parts are REACH Unaffected and classified as EAR99 for export control. The FR01FC10P-S additionally carries ROHS3 compliance certification.

Q: What body material difference exists?

A: The DRFC10P uses glass-filled polybutylene terephthalate (PBT); the FR01FC10P-S uses glass-filled polyamide (PA) nylon. This material change affects mechanical properties and the washable feature availability.
