MRA112-CG Rotary Switch Equivalent & Substitute Parts

Part Overview

The MRA112-CG is a rotary switch manufactured by NKK Switches, designed for panel-mount applications requiring adjustable position selection from 2 to 12 positions. This single-pole, single-deck switch operates at 250mA AC and 125V AC, utilizing non-shorting (BBM) contact timing with a 30° angle of throw. The component features a knob actuator with a 15.80mm length and is terminated via PC pins for through-hole mounting.

The MRA112-CG carries an Obsolete product status. Locating equivalent or substitute components becomes necessary when original stock is depleted or when design requirements mandate components with active manufacturing support and extended availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MRA112-CG is determined by the following critical parameters:

• Electrical Specifications: Current rating (250mA AC minimum), voltage rating (125V AC minimum), and circuit configuration (SP12T or compatible)
• Mechanical Compatibility: Panel mount through-hole termination with PC pins, knob actuator, and 6.35mm circular panel cutout
• Position Range: Adjustable index stops supporting 2 to 12 positions
• Contact Characteristics: Non-shorting (BBM) contact timing and copper with silver-finish contacts
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The MRAN112-CG qualifies as a manufacturer-recommended substitute based on alignment with these core parameters within the NKK Switches product family.

Engineering Selection Recommendations

The MRAN112-CG is designated as the manufacturer-recommended substitute for the obsolete MRA112-CG. Selection of the MRAN112-CG is supported by:

• Active Product Status: The MRAN112-CG maintains active manufacturing status, ensuring continued availability and supply chain reliability compared to the obsolete MRA112-CG
• Regulatory Compliance: Both components maintain alignment with ROHS3 and REACH requirements, supporting compliance-driven design requirements
• Manufacturer Continuity: Both components originate from NKK Switches, ensuring design consistency and technical support within the same product family
• Inventory Availability: The MRAN112-CG demonstrates higher current inventory levels (1130 Pcs), supporting procurement timelines and production schedules

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match between the MRA112-CG and its substitute?

A: The substitute must maintain a minimum current rating of 250mA AC, a voltage rating of 125V AC, and a circuit configuration of SP12T or equivalent. These parameters define the electrical load capacity and switching capability required for the application.

Q: Are the mechanical mounting dimensions identical between MRA112-CG and MRAN112-CG?

A: Both components are specified for panel mount, through-hole termination with PC pins and a 6.35mm circular panel cutout. Detailed dimensional specifications for the MRAN112-CG should be confirmed against the MRA112-CG mechanical drawing to ensure fit within existing panel assemblies.

Q: Why is the MRA112-CG listed as Obsolete?

A: Obsolete status indicates that the manufacturer has discontinued active production and support for this component. The MRAN112-CG, with Active product status, represents the current manufacturing equivalent within the NKK Switches portfolio.

Q: Can the MRAN112-CG be used as a direct replacement in existing designs?

A: The MRAN112-CG is manufacturer-recommended as a substitute. Confirmation of electrical and mechanical compatibility with the specific application circuit and panel assembly is necessary before implementation.

Q: What packaging options are available for these components?

A: Both the MRA112-CG and MRAN112-CG are supplied in Bulk packaging. Consult the manufacturer for alternative packaging configurations if required for specific procurement or assembly processes.
