DRKR16P Equivalent & Substitute Parts

Part Overview

The DRKR16P is a hexadecimal rotary DIP switch manufactured by NKK Switches, designed for through-hole mounting applications requiring 16-position selection capability at 100mA and 5VDC. This component features a rotary shaft actuator with raised level positioning and gold-plated copper contacts sealed for environmental protection.

The DRKR16P is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Engineering Selection Recommendations

The FR01KR16P-S is an active production substitute for the obsolete DRKR16P. Both components are manufactured by NKK Switches and share identical electrical specifications, circuit configuration, and mechanical interface requirements.

The FR01KR16P-S offers the following advantages for new designs and ongoing supply:

Active Product Status: Ensures continued availability and manufacturing support
Regulatory Compliance: ROHS3 compliant and REACH unaffected, meeting current environmental standards
Extended Operating Temperature: Rated to 85°C versus 75°C for the original part
Reduced Height Profile: 0.426" (10.82mm) versus 0.508" (12.91mm), providing improved PCB layout flexibility

Design considerations for substitution:

Mechanical Life Rating: FR01KR16P-S rated at 10,000 steps versus 20,000 steps for DRKR16P. Applications requiring extended cycle life should evaluate actual usage patterns against this specification.
Body Material: FR01KR16P-S uses polyamide (PA) nylon glass-filled material versus polybutylene terephthalate (PBT) for the original. Both materials are suitable for standard through-hole PCB assembly environments.
Washability: DRKR16P is washable; FR01KR16P-S is not. Post-assembly cleaning processes should be evaluated if required.

Frequently Asked Questions (FAQ)

Q: Can FR01KR16P-S be used as a direct replacement for DRKR16P in existing designs?

A: Yes. Both components share identical electrical ratings (100mA, 5VDC), circuit type (hexadecimal 16-position), actuator configuration (rotary with shaft), mounting method (through-hole), and termination style (PC pin). The FR01KR16P-S is electrically and mechanically compatible for PCB assembly and functional operation.

Q: What are the physical differences between these parts?

A: The primary physical difference is height above board: DRKR16P measures 0.508" (12.91mm) while FR01KR16P-S measures 0.426" (10.82mm). This 0.082" reduction may affect PCB layout and component clearance in space-constrained applications. Both parts maintain identical length (0.394") and pitch (0.100").

Q: Are there differences in mechanical durability?

A: Yes. DRKR16P is rated for 20,000 mechanical and electrical steps, while FR01KR16P-S is rated for 10,000 steps. For applications with high-frequency position changes, the original part specification should be compared against actual usage requirements.

Q: What packaging is available for FR01KR16P-S?

A: FR01KR16P-S is supplied in tube packaging, whereas DRKR16P was supplied with standard packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both DRKR16P and FR01KR16P-S are REACH unaffected and classified as EAR99 for export control purposes. FR01KR16P-S additionally carries ROHS3 compliance certification, meeting current environmental standards for new production.

Q: Can FR01KR16P-S be used in applications requiring post-assembly washing?

A: DRKR16P is specified as washable; FR01KR16P-S is not. If your manufacturing process includes aqueous or solvent-based cleaning, confirm compatibility with the FR01KR16P-S material composition and sealed design before implementation.
