DRFR16H Equivalent & Substitute Parts

Part Overview

The DRFR16H is a hexadecimal rotary DIP switch manufactured by NKK Switches, designed for through-hole, right-angle mounting applications requiring tool actuation. This component operates at 100mA and 5VDC with 16 selectable positions. The DRFR16H is classified as obsolete, making identification of equivalent substitute parts essential for ongoing production support and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DRFR16H are identified based on electrical and mechanical parameter compatibility. The following criteria determine substitution eligibility:

Critical Parameters (Must Match):

• Circuit type: Hexadecimal
• Number of positions: 16
• Current rating: 100mA
• Voltage rating: 5VDC
• Actuator type: Rotary for Tool
• Mounting type: Through Hole, Right Angle
• Pitch: 0.100" (2.54mm)
• Height above board: 0.394" (10.00mm)
• Termination style: PC Pin

Allowable Variations:

• Contact material: Copper or Copper Alloy
• Contact finish: Gold (consistent across all parts)
• Body material: PBT Glass Filled or PA Nylon Glass Filled
• Operating temperature range: Extended range acceptable (-25°C ~ 85°C)
• Mechanical and electrical life: Lower values acceptable for substitution
• Washable feature: Not required for substitution
• Packaging format: Tube acceptable for through-hole components

The FR01FR16H-S and FR01FR16H-06XL-S meet all critical electrical and mechanical parameters, making them suitable substitutes for the obsolete DRFR16H.

Parameter Comparison

Engineering Selection Recommendations

Both FR01FR16H-S and FR01FR16H-06XL-S are active product alternatives to the obsolete DRFR16H. Selection between these two substitutes is determined by packaging requirements and availability:

FR01FR16H-S is recommended for standard production applications. This part maintains active product status with ROHS3 compliance and extended operating temperature range (-25°C ~ 85°C). Inventory availability is 16,412 pieces.

FR01FR16H-06XL-S is functionally equivalent to FR01FR16H-S with identical electrical and mechanical specifications. This variant is packaged in tube format and maintains the same compliance certifications. Inventory availability is 1,341 pieces.

Both substitutes satisfy REACH and EAR99 export classification requirements. The extended operating temperature range of the FR01 series provides additional thermal margin compared to the original DRFR16H specification.

Frequently Asked Questions (FAQ)

Q: Can FR01FR16H-S and FR01FR16H-06XL-S be used interchangeably with DRFR16H?

A: Yes. Both parts match all critical electrical parameters (100mA, 5VDC, hexadecimal 16-position), mechanical dimensions (0.394" height, 0.100" pitch, through-hole right-angle mounting), and contact specifications (gold-plated). The primary difference is packaging format (tube) and body material composition (PA nylon versus PBT), which do not affect electrical or mechanical function.

Q: What is the difference between FR01FR16H-S and FR01FR16H-06XL-S?

A: Both parts are electrically and mechanically identical. The designation difference reflects packaging configuration. FR01FR16H-06XL-S is the tube-packaged variant. Selection depends on assembly process requirements and packaging compatibility with your production line.

Q: Are there compliance differences between DRFR16H and the FR01 series substitutes?

A: The FR01 series substitutes carry ROHS3 compliance certification, whereas ROHS status is not specified for the obsolete DRFR16H. Both the original and substitute parts are REACH Unaffected and classified as EAR99 for export purposes.

Q: Will the lower mechanical and electrical life ratings of FR01 substitutes affect performance?

A: The FR01 series is rated for 10,000 steps mechanical and electrical life, compared to 20,000 steps for DRFR16H. This specification reflects the design of the FR01 series. Selection should be based on your application's cycle life requirements. For applications requiring 20,000+ cycles, consult with the manufacturer regarding alternative options.

Q: Are there thermal performance differences?

A: The FR01 series operates across -25°C ~ 85°C, providing a 10°C extended upper temperature limit compared to DRFR16H (-25°C ~ 75°C). This extended range is beneficial for applications in elevated ambient conditions.
