MRA112-CC Equivalent & Substitute Parts

Part Overview

The MRA112-CC is a rotary switch manufactured by NKK Switches, designed for applications requiring selectable positions from 2 to 12. This single-pole, 12-throw (SP12T) switch operates at 250mA AC and 125 VAC, featuring a non-shorting contact configuration with adjustable index stops. The component is panel-mounted through-hole with a knob actuator and silver-plated copper contacts.

The MRA112-CC is classified as obsolete. Locating equivalent or substitute components is necessary to support legacy system maintenance, repair, and continued operation where original stock is depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MRA112-CC is based on electrical and mechanical compatibility within the following critical parameters:

• Circuit Configuration: SP12T topology (single pole, 12 throw) ensures functional equivalence in position selection and switching logic
• Current and Voltage Ratings: 250mA AC at 125 VAC establishes the electrical load capacity
• Contact Timing: Non-shorting (BBM) contact behavior maintains signal integrity in applications sensitive to contact bounce
• Mounting and Termination: Panel mount through-hole with PC pin termination ensures mechanical and electrical interface compatibility
• Contact Material and Finish: Copper with silver plating provides consistent contact resistance and reliability

The MRAN112-CC is identified as a manufacturer-recommended substitute. Both components share the same manufacturer (NKK Switches), circuit configuration (SP12T), electrical ratings, and mounting specifications. The MRAN112-CC represents an active product line continuation, making it suitable for direct substitution in legacy applications.

Parameter Comparison

Engineering Selection Recommendations

The MRAN112-CC is the manufacturer-recommended substitute for the obsolete MRA112-CC. Both components are manufactured by NKK Switches and are designated within the same product family (MR/MRAN series). The MRAN112-CC carries active product status, ensuring ongoing availability and support.

Selection of the MRAN112-CC is appropriate for applications requiring direct replacement of the MRA112-CC. The active product status of the MRAN112-CC provides supply chain continuity and access to current manufacturing batches. Both components maintain ROHS3 compliance, supporting regulatory requirements in modern applications.

When detailed electrical and mechanical specifications for the MRAN112-CC are required for final validation, consult the manufacturer's current datasheet to confirm parameter alignment with application requirements.

Frequently Asked Questions (FAQ)

Q: Why is the MRA112-CC classified as obsolete? A: The MRA112-CC has been discontinued by NKK Switches. The MRAN112-CC represents the active product line continuation within the same manufacturer's rotary switch portfolio.

Q: Can the MRAN112-CC directly replace the MRA112-CC? A: Yes. The MRAN112-CC is the manufacturer-recommended substitute. Both components share the same manufacturer and are part of the same product family, ensuring mechanical and electrical compatibility for panel-mount rotary switch applications.

Q: What are the critical parameters for substitution? A: Substitution is valid when the following parameters match: circuit configuration (SP12T), current rating (250mA AC), voltage rating (125 VAC), contact timing (non-shorting), mounting type (panel mount through-hole), and termination style (PC pin).

Q: Does the MRAN112-CC meet the same compliance standards? A: The MRA112-CC is ROHS3 compliant. Compliance status for the MRAN112-CC should be confirmed with the manufacturer's current datasheet to ensure regulatory alignment with your application.

Q: What is the difference in packaging between these parts? A: Both the MRA112-CC and MRAN112-CC are supplied in bulk packaging, making them equivalent for procurement and assembly processes.

Q: Are there any mechanical differences in mounting? A: Both components feature panel mount, through-hole installation with a 6.35mm circular panel cutout. Mechanical compatibility is maintained for direct substitution in existing designs.
