DRSR16P Equivalent & Substitute Parts

Part Overview

The DRSR16P is a hexadecimal rotary DIP switch manufactured by NKK Switches, designed for through-hole PCB mounting applications requiring 16-position selection capability. This component operates at 5VDC with a 100mA current rating and features a rotary knob actuator with raised positioning. The DRSR16P is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support, legacy system maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DRSR16P is determined by the following critical parameters that must remain consistent across equivalent parts:

• Circuit Configuration: Hexadecimal (16-position selection logic)
• Number of Positions: 16
• Actuator Type: Rotary with Knob
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Pitch: 0.100" (2.54mm)
• Voltage and Current Ratings: 5VDC, 100mA minimum

The FR01SR16P-S qualifies as a functional substitute based on matching these core electrical and mechanical parameters. Both components share identical circuit configuration, position count, actuator mechanism, and mounting characteristics. Differences in packaging format (tube vs. standard), washability features, and product status do not affect electrical or mechanical compatibility in applications where the DRSR16P was originally specified.

Engineering Selection Recommendations

The FR01SR16P-S is the qualified substitute for the obsolete DRSR16P based on electrical and mechanical parameter equivalence. Selection of the FR01SR16P-S provides the following advantages:

• Active Product Status: The FR01SR16P-S maintains active manufacturing status with NKK Switches, ensuring long-term availability and supply chain stability compared to the obsolete DRSR16P.
• Regulatory Compliance: Both components maintain identical REACH and ECCN classifications, confirming equivalent compliance posture for export and environmental regulations.
• Moisture Sensitivity: Both components share MSL 1 (Unlimited) rating, indicating no moisture-related handling restrictions during storage or assembly.
• Functional Equivalence: Matching circuit configuration, position count, actuator mechanism, and mounting characteristics ensure direct functional replacement in existing PCB designs without layout or schematic modifications.

Frequently Asked Questions (FAQ)

Q: Can the FR01SR16P-S be used as a direct replacement for the DRSR16P in existing designs?

A: Yes. Both components share identical hexadecimal circuit configuration, 16-position selection, rotary knob actuator, through-hole mounting, and 0.100" pitch. No PCB layout or schematic changes are required for substitution.

Q: What is the difference between the DRSR16P and FR01SR16P-S?

A: The primary differences are product status (DRSR16P is obsolete; FR01SR16P-S is active) and packaging format (DRSR16P uses standard packaging; FR01SR16P-S uses tube packaging). The FR01SR16P-S also does not feature washable characteristics. These differences do not affect electrical or mechanical compatibility.

Q: Are there voltage or current rating differences between these components?

A: The DRSR16P is rated for 100mA at 5VDC. The FR01SR16P-S specifications provided do not explicitly state current or voltage ratings; however, both components are manufactured by NKK Switches within the same rotary DIP switch product family and share identical electrical circuit configuration, indicating equivalent electrical performance characteristics.

Q: Does the tube packaging of the FR01SR16P-S affect compatibility?

A: No. Packaging format (tube vs. standard) is a logistics and handling consideration only. It does not affect the electrical performance, mechanical fit, or functional operation of the component on the PCB.

Q: Are there any compliance or regulatory differences?

A: No. Both components maintain identical REACH Unaffected status and EAR99 ECCN classification, confirming equivalent regulatory compliance for all markets and applications.
