MRA206-BC Equivalent & Substitute Parts

Part Overview

The MRA206-BC is a rotary switch manufactured by NKK Switches, designed for panel-mount applications requiring multi-position selection. This component features a 2-6 position adjustable configuration with dual-pole, six-throw (DP6T) switching capability, rated for 250mA AC at 125VAC. The product is classified as obsolete, making identification of equivalent and substitute parts essential for system maintenance, repair, and component sourcing in legacy applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MRA206-BC is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Current rating (250mA AC), voltage rating (125VAC), and circuit configuration (DP6T) must remain unchanged
• Mechanical Compatibility: Panel mount configuration, through-hole termination, and physical dimensions (6.35mm circular cutout, 17.00mm depth) must be maintained
• Contact Characteristics: Non-shorting (BBM) contact timing and copper-silver contact material ensure signal integrity
• Operational Range: Adjustable 2-6 position capability with 30° angle of throw must be preserved

The MRAN206-BC qualifies as a direct substitute based on matching electrical ratings, circuit topology, and mechanical mounting specifications. The transition from obsolete (MRA206-BC) to active product status (MRAN206-BC) reflects NKK Switches' product line evolution while maintaining functional equivalence.

Engineering Selection Recommendations

The MRAN206-BC is identified as the manufacturer-recommended substitute for the obsolete MRA206-BC. Selection of this substitute is supported by:

• Product Status Transition: The MRAN206-BC maintains active product status with NKK Switches, ensuring ongoing availability and supply chain continuity
• Regulatory Compliance: The MRA206-BC is ROHS3 compliant and REACH unaffected, establishing a baseline for environmental and regulatory requirements
• Manufacturer Endorsement: NKK Switches explicitly lists MRAN206-BC as the recommended replacement, indicating functional and mechanical equivalence

For applications requiring the MRA206-BC, the MRAN206-BC provides direct substitution capability. Verification of complete electrical and mechanical specifications for the MRAN206-BC is necessary prior to final component selection to confirm all parameters match application requirements.

Frequently Asked Questions (FAQ)

Q: Why is the MRA206-BC classified as obsolete? A: The MRA206-BC has been superseded by the MRAN206-BC in NKK Switches' product portfolio. Obsolete status indicates the part is no longer in active production, though existing inventory may remain available.

Q: Can the MRAN206-BC directly replace the MRA206-BC in existing applications? A: The MRAN206-BC is the manufacturer-recommended substitute and is designed to provide functional equivalence. However, complete specification verification is required to confirm all electrical, mechanical, and environmental parameters align with application requirements.

Q: What are the key electrical parameters that must match for substitution? A: Current rating (250mA AC), voltage rating (125VAC), and circuit configuration (DP6T) are the primary electrical parameters that determine substitution compatibility. These parameters must remain constant across the main part and substitute.

Q: Are there packaging differences between MRA206-BC and MRAN206-BC? A: The MRA206-BC is supplied in standard packaging, while the MRAN206-BC is supplied in bulk packaging. This difference does not affect component functionality or mechanical compatibility.

Q: What compliance certifications apply to these parts? A: The MRA206-BC is ROHS3 compliant and REACH unaffected. Compliance status for the MRAN206-BC should be confirmed with the manufacturer prior to procurement for applications with specific regulatory requirements.

Q: Are there any mechanical dimension differences between these parts? A: Both parts are designed for panel-mount, through-hole applications with identical mechanical specifications (6.35mm circular cutout, 17.00mm depth behind panel). Mechanical compatibility is maintained across the substitution.
