DRFR16P Equivalent & Substitute Parts

Part Overview

The DRFR16P is a hexadecimal rotary DIP switch manufactured by NKK Switches, designed for through-hole mounting applications requiring 16-position selection capability. This component operates at 100mA and 5VDC, featuring a tool-actuated rotary mechanism with a flush, recessed actuator level. The DRFR16P is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DRFR16P is determined by strict alignment of the following critical parameters:

• Circuit Configuration: Hexadecimal (16-position) selection capability
• Electrical Ratings: 100mA current rating and 5VDC voltage rating
• Actuator Mechanism: Rotary tool-actuated design with flush, recessed actuator level
• Mounting Architecture: Through-hole PCB mounting with 0.100" (2.54mm) pitch
• Termination Interface: PC pin termination style
• Contact System: Gold-finished copper or copper alloy contacts

The FR01FR16P-S meets all substitution criteria. While certain mechanical and thermal parameters differ, these variations remain within acceptable tolerance for equivalent functional performance in applications originally specified for the DRFR16P.

Engineering Selection Recommendations

The FR01FR16P-S is the designated equivalent substitute for the obsolete DRFR16P. Selection of the FR01FR16P-S is supported by the following factors:

• Product Status: The FR01FR16P-S maintains active production status, ensuring long-term component availability and supply chain continuity.
• Regulatory Compliance: The FR01FR16P-S carries ROHS3 compliance certification, meeting current environmental and hazardous substance restrictions.
• Functional Equivalence: Both components share identical electrical ratings, circuit configuration, and mechanical interface specifications required for direct substitution.
• Enhanced Operating Range: The FR01FR16P-S supports an extended upper operating temperature limit of 85°C compared to the DRFR16P's 75°C maximum, providing additional thermal margin in applications.
• Reduced Profile: The FR01FR16P-S features a lower height above board (0.150" versus 0.232"), which may provide design flexibility in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the FR01FR16P-S be used as a direct replacement for the DRFR16P in existing designs?

A: Yes. Both components share identical electrical ratings (100mA, 5VDC), hexadecimal circuit configuration, rotary tool-actuated mechanism, through-hole mounting with 0.100" pitch, and PC pin termination. The FR01FR16P-S is electrically and mechanically compatible for direct substitution.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Height above board—FR01FR16P-S is 0.150" versus DRFR16P at 0.232"; (2) Operating temperature upper limit—FR01FR16P-S supports 85°C versus DRFR16P at 75°C; (3) Contact material—FR01FR16P-S uses copper alloy versus copper in the DRFR16P; (4) Body material—FR01FR16P-S uses polyamide (PA) nylon versus polybutylene terephthalate (PBT) in the DRFR16P; (5) Product status—FR01FR16P-S is active production while DRFR16P is obsolete.

Q: Does the reduced height of the FR01FR16P-S affect PCB layout compatibility?

A: The FR01FR16P-S maintains identical pitch (0.100"), termination style (PC pin), and mounting type (through-hole) as the DRFR16P. The reduced height may require verification of clearance in applications with tight vertical constraints, but does not affect electrical or functional compatibility.

Q: Is the FR01FR16P-S available in the same packaging as the DRFR16P?

A: The FR01FR16P-S is supplied in tube packaging. Packaging format should be confirmed against procurement requirements for your application.

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

A: The DRFR16P specifies 20,000 mechanical steps, while the FR01FR16P-S specifies 10,000 mechanical steps. Application duty cycle requirements should be evaluated against these specifications.

Q: Are there any washability differences?

A: Yes. The DRFR16P is specified as washable, while the FR01FR16P-S is not washable. If post-assembly cleaning is required, this difference must be evaluated for your manufacturing process.
