MRA112-BE Rotary Switch Equivalent & Substitute Parts

Part Overview

The MRA112-BE is a rotary switch manufactured by NKK Switches, classified as a 2-12 position SP12T rotary switch rated for 250mA AC at 125 VAC. This component features adjustable index stops, non-shorting contact timing (BBM), and panel mount through-hole termination with a circular 6.35mm diameter cutout. The MRA112-BE is currently listed as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MRA112-BE is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Current rating (250mA AC), voltage rating (125 VAC), and circuit configuration (SP12T)
• Mechanical Compatibility: Panel mount through-hole termination, PC pin termination style, and panel cutout dimensions (6.35mm circular)
• Operational Characteristics: Number of positions (2-12), contact timing (non-shorting BBM), and angle of throw (30°)
• Material Specifications: Copper contact material with silver finish
• Regulatory Compliance: RoHS3 compliance and REACH status

The MRAN112-BE qualifies as a manufacturer-recommended substitute based on alignment with these core parameters.

Parameter Comparison

Engineering Selection Recommendations

The MRAN112-BE is designated as the manufacturer-recommended substitute for the obsolete MRA112-BE. As an active product from NKK Switches, the MRAN112-BE provides continuity for applications requiring rotary switch functionality in panel-mount configurations. The transition from obsolete to active product status ensures ongoing availability and manufacturing support.

Selection of the MRAN112-BE is appropriate for new procurement and system maintenance where the MRA112-BE is no longer available. Both components originate from the same manufacturer, supporting design consistency and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Why is the MRA112-BE listed as obsolete? A: The MRA112-BE has reached end-of-life status with NKK Switches. The MRAN112-BE serves as the active replacement, ensuring continued availability of equivalent rotary switch functionality.

Q: What are the critical parameters for substitution compatibility? A: Substitution requires equivalence in current rating (250mA AC), voltage rating (125 VAC), circuit configuration (SP12T), mounting type (panel mount through-hole), termination style (PC pin), and panel cutout dimensions (6.35mm circular).

Q: Is the MRAN112-BE a direct mechanical replacement? A: Both components are manufactured by NKK Switches with panel mount through-hole termination and PC pin termination style, supporting direct mechanical compatibility in standard panel-mount applications.

Q: What is the packaging difference between these parts? A: The MRA112-BE packaging is listed as standard, while the MRAN112-BE is supplied in bulk packaging. Packaging selection depends on procurement volume and inventory management requirements.

Q: Are both parts RoHS compliant? A: The MRA112-BE is confirmed ROHS3 compliant. Compliance status for the MRAN112-BE should be confirmed with the manufacturer or distributor for specific applications requiring regulatory documentation.
