DRFC10H Equivalent & Substitute Parts

Part Overview

The DRFC10H is a rotary DIP switch manufactured by NKK Switches, designed for BCD complement applications requiring 10-position selection with 100mA at 5VDC. This component features through-hole, right-angle mounting with tool-actuated rotary operation and sealed construction for washable applications.

The DRFC10H is classified as obsolete. Equivalent substitute parts from the active FR01 series are available to maintain design continuity and ensure ongoing component availability for new production and field replacements.

Substitute Part Grouping Explanation

Substitution of the DRFC10H is based on electrical and mechanical parameter equivalence within the NKK Switches FR01 series. The following parameters must remain constant for direct substitution:

Circuit configuration: BCD Complement
Number of positions: 10
Current rating: 100mA
Voltage rating: 5VDC
Actuator type: Rotary for Tool
Mounting configuration: Through Hole, Right Angle
Pitch: 0.100" (2.54mm)
Height above board: 0.394" (10.00mm)
Contact finish: Gold
Termination style: PC Pin

The FR01FC10H-S and FR01FC10H-06XL-S maintain all critical electrical and mechanical parameters required for functional equivalence. Both substitute parts are from the active FR01 series and provide improved availability compared to the obsolete DRFC10H.

Engineering Selection Recommendations

Both FR01FC10H-S and FR01FC10H-06XL-S are suitable substitutes for the obsolete DRFC10H based on electrical and mechanical equivalence. The FR01 series parts are active products with established supply chains and ROHS3 compliance certification.

Selection between FR01FC10H-S and FR01FC10H-06XL-S depends on packaging requirements. The FR01FC10H-S is supplied in standard tube packaging, while the FR01FC10H-06XL-S is supplied in tube packaging with extended lead specifications. Both maintain identical electrical and mechanical performance characteristics.

Applications requiring extended operating temperature range above 75°C benefit from the FR01 series upper temperature rating of 85°C. Applications with mechanical life requirements exceeding 10,000 steps should evaluate the DRFC10H specification of 20,000 steps against actual duty cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can FR01FC10H-S and FR01FC10H-06XL-S be used interchangeably with DRFC10H?

A: Both FR01 series parts maintain electrical and mechanical equivalence to DRFC10H across all critical parameters: BCD complement circuit, 10-position selection, 100mA current rating, 5VDC voltage rating, rotary tool actuator, through-hole right-angle mounting, and 0.100" pitch. Direct substitution is supported for applications within the specified operating parameters.

Q: What are the differences between FR01FC10H-S and FR01FC10H-06XL-S?

A: Both parts are electrically and mechanically identical. The primary difference is packaging designation. The FR01FC10H-06XL-S designation indicates extended lead specifications. Consult packaging documentation for specific lead length and configuration details.

Q: Are there temperature rating differences between DRFC10H and the FR01 substitutes?

A: DRFC10H operates from -25°C to 75°C. FR01FC10H-S and FR01FC10H-06XL-S operate from -25°C to 85°C, providing a 10°C extended upper temperature range. Applications operating near the upper temperature limit should confirm compatibility with the FR01 series rating.

Q: What is the mechanical life difference between DRFC10H and FR01 substitutes?

A: DRFC10H specifies 20,000 mechanical and electrical steps. FR01FC10H-S and FR01FC10H-06XL-S specify 10,000 mechanical and electrical steps. Applications requiring operation beyond 10,000 steps should evaluate actual duty cycle requirements against substitute part specifications.

Q: Are FR01 series parts RoHS compliant?

A: FR01FC10H-S and FR01FC10H-06XL-S are ROHS3 compliant. DRFC10H RoHS status is not specified in available documentation.

Q: What is the washable characteristic difference?

A: DRFC10H is specified as washable. FR01FC10H-S and FR01FC10H-06XL-S are not specified as washable. Applications requiring washable construction should confirm FR01 series compatibility with specific cleaning processes.
