DRFC16H Equivalent & Substitute Parts

Part Overview

The DRFC16H is a 16-position hexadecimal complement 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 a sealed design suitable for applications requiring position encoding and configuration selection.

The DRFC16H 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.

Substitute Part Grouping Explanation

Substitution for the DRFC16H is determined by strict equivalence across the following critical parameters:

Circuit configuration: Hexadecimal Complement (16-position encoding)
Electrical ratings: 100mA current, 5VDC voltage
Mechanical interface: Through-hole, right-angle mounting with 0.100" pitch
Actuator mechanism: Rotary tool-actuated design
Physical envelope: 0.394" height above board, 0.394" length
Contact system: Gold-finished copper or copper alloy contacts with PC pin termination

The substitute parts FR01FC16H-S and FR01FC16H-06XL-S meet all critical functional and mechanical parameters. Both are manufactured by NKK Switches and maintain identical electrical specifications, mounting geometry, and circuit functionality. These parts are classified as active products, ensuring ongoing availability and supply chain support.

Engineering Selection Recommendations

Both FR01FC16H-S and FR01FC16H-06XL-S are direct functional equivalents to the obsolete DRFC16H. Selection between these two substitute parts is determined by packaging and compliance requirements:

FR01FC16H-S is supplied in tube packaging and is ROHS3 compliant, making it suitable for applications requiring regulatory compliance with modern environmental standards.

FR01FC16H-06XL-S is also supplied in tube packaging and is ROHS3 compliant, offering identical electrical and mechanical performance.

Both substitute parts operate across an extended temperature range (-25°C to 85°C compared to the original -10°C to 75°C specification), providing improved thermal performance margins. The mechanical and electrical life ratings of both substitutes are 10,000 steps, compared to 20,000 steps for the original DRFC16H. This difference must be evaluated against application duty cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can FR01FC16H-S and FR01FC16H-06XL-S be used interchangeably with DRFC16H?

A: Both parts are functionally equivalent. They share identical electrical ratings (100mA, 5VDC), circuit configuration (16-position hexadecimal complement), and mechanical interface (through-hole, right-angle, 0.100" pitch). The primary differences are product status (active vs. obsolete), packaging format (tube), and compliance certifications (ROHS3). Mechanical and electrical life ratings differ at 10,000 steps versus 20,000 steps for the original.

Q: What is the difference between FR01FC16H-S and FR01FC16H-06XL-S?

A: Both parts are manufactured by NKK Switches and share identical electrical specifications, mechanical dimensions, and circuit functionality. The designation difference reflects internal NKK product line variations. Both are supplied in tube packaging and are ROHS3 compliant. Consult NKK Switches documentation for specific application guidance on part number selection.

Q: Are the substitute parts ROHS compliant?

A: Yes. Both FR01FC16H-S and FR01FC16H-06XL-S are ROHS3 compliant. The original DRFC16H does not specify RoHS status.

Q: What is the impact of the reduced mechanical and electrical life rating?

A: The substitute parts are rated for 10,000 steps of mechanical and electrical life, compared to 20,000 steps for the DRFC16H. Applications requiring operation beyond 10,000 cycles must evaluate this specification against actual duty cycle requirements.

Q: Are there any temperature rating differences?

A: Yes. The substitute parts operate across -25°C to 85°C, compared to -25°C to 75°C for the original DRFC16H. This represents an extended upper temperature margin of 10°C.

Q: What packaging formats are available?

A: Both substitute parts are supplied in tube packaging. The original DRFC16H packaging format is not specified in the provided data.
