DRFC16P Equivalent & Substitute Parts

Part Overview

The DRFC16P is a 16-position hexadecimal complement rotary DIP switch manufactured by NKK Switches, designed for through-hole mounting applications requiring tool actuation. This component operates at 100mA and 5VDC with a sealed design suitable for controlled environments. The DRFC16P 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

Substitution of the DRFC16P is based on the following critical parameters that must remain constant:

• Circuit configuration: Hexadecimal Complement (16-position logic)
• Electrical specifications: 100mA current rating and 5VDC voltage rating
• Mechanical interface: Through-hole mounting with PC pin termination
• Pitch spacing: 0.100" (2.54mm) full pitch
• Actuator mechanism: Rotary tool-actuated design

The FR01FC16P-S meets these core functional requirements while offering improved product status (Active) and enhanced temperature operating range. Differences in height above board, body material composition, and mechanical life cycles are secondary parameters that do not affect primary circuit functionality within the specified electrical envelope.

Parameter Comparison

Engineering Selection Recommendations

The FR01FC16P-S is the direct functional equivalent for DRFC16P applications. Both components share identical electrical specifications (100mA, 5VDC), circuit logic (hexadecimal complement, 16 positions), and mechanical interfaces (through-hole, PC pin, 0.100" pitch).

The FR01FC16P-S offers the following advantages:

• Active product status with ongoing manufacturer support
• Extended operating temperature range (-25°C to 85°C versus -75°C)
• Reduced height above board (3.81mm versus 5.90mm), beneficial for space-constrained PCB layouts
• ROHS3 compliance certification

Selection of FR01FC16P-S is appropriate for new designs and replacement applications where the DRFC16P is no longer available. The reduced profile and improved temperature range provide additional design margin without compromising electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can FR01FC16P-S directly replace DRFC16P in existing designs?

A: Yes. Both components share identical electrical ratings (100mA, 5VDC), circuit configuration (hexadecimal complement, 16 positions), and mechanical interfaces (through-hole mounting, PC pin termination, 0.100" pitch). The FR01FC16P-S has a lower profile (3.81mm versus 5.90mm), which is compatible with standard PCB layouts.

Q: What is the difference in mechanical life between these components?

A: DRFC16P specifies 20,000 mechanical steps, while FR01FC16P-S specifies 10,000 mechanical steps. For applications requiring extended cycle life, this difference should be evaluated against actual usage patterns.

Q: Are there packaging differences between DRFC16P and FR01FC16P-S?

A: DRFC16P is supplied in standard packaging, while FR01FC16P-S is supplied in tube packaging. Both are suitable for through-hole assembly processes.

Q: Does the body material change affect performance?

A: DRFC16P uses polybutylene terephthalate (PBT) glass-filled material, while FR01FC16P-S uses polyamide (PA) nylon glass-filled material. Both materials provide adequate mechanical strength and environmental protection for the specified operating temperature ranges.

Q: Are both components RoHS compliant?

A: DRFC16P status is not specified in available data. FR01FC16P-S is ROHS3 compliant. Both components are REACH unaffected and classified as EAR99 for export control purposes.
