MRA206-CE Rotary Switch Equivalent & Substitute Parts

Part Overview

The MRA206-CE is a rotary switch manufactured by NKK Switches, classified as a 2–6 position, dual-pole, six-throw (DP6T) panel-mount component rated for 250mA AC at 125 VAC. The part is currently obsolete, which necessitates identification of functionally equivalent alternatives for ongoing maintenance, repair, and new design applications. The MRA206-CE features a non-shorting (BBM) contact timing configuration with adjustable index stops and a process-sealed design suitable for industrial control panels.

Substitute Part Grouping Explanation

The MRAN206-CE qualifies as a direct substitute for the MRA206-CE based on the following criteria:

Electrical Equivalence: Both parts maintain identical circuit configuration (DP6T), current rating (250mA AC), voltage rating (125 VAC), and contact timing (Non-Shorting BBM). These parameters define the electrical load-switching capability and are non-negotiable for substitution.

Mechanical Compatibility: Both parts share the same mounting type (Panel Mount, Through Hole), termination style (PC Pin), panel cutout dimensions (Circular – 6.35mm Diameter), and depth behind panel (17.00mm). These parameters ensure physical interchangeability in existing panel layouts.

Functional Parameters: Both parts feature adjustable index stops, 30° angle of throw, knob actuator type, and identical contact material and finish (Copper with Silver). These parameters preserve operational characteristics and contact reliability.

Compliance: Both parts are ROHS3 compliant and carry MSL 1 rating, meeting regulatory and environmental requirements.

Key Differentiator: The MRAN206-CE is active in production with bulk packaging, whereas the MRA206-CE is obsolete. The MRAN206-CE features a slightly shorter actuator length (13.00mm versus 15.80mm), which must be evaluated for clearance in the specific panel application.

Parameter Comparison

Engineering Selection Recommendations

The MRAN206-CE is the manufacturer-recommended substitute for the obsolete MRA206-CE. Both parts are ROHS3 compliant and carry identical MSL 1 ratings, ensuring regulatory and environmental compatibility.

The primary consideration for substitution is the actuator length difference: the MRAN206-CE features a 13.00mm actuator length compared to the MRA206-CE's 15.80mm. This 2.80mm reduction must be evaluated against the specific panel design to ensure adequate clearance and operator accessibility. If the original design accommodates the shorter actuator or if panel geometry permits the change, the MRAN206-CE provides a direct electrical and mechanical replacement.

All other electrical, mechanical, and functional parameters are identical, confirming full substitution capability within the constraints of actuator length clearance.

Frequently Asked Questions (FAQ)

Q: Can the MRAN206-CE replace the MRA206-CE in existing applications?

A: Yes, provided the panel design accommodates the 2.80mm shorter actuator length (13.00mm versus 15.80mm). All electrical ratings, circuit configurations, mounting dimensions, and contact characteristics are identical.

Q: What is the significance of the actuator length difference?

A: The actuator length affects operator reach and clearance behind the panel. The MRAN206-CE's shorter actuator may require panel geometry evaluation to ensure it does not interfere with internal components or create accessibility issues.

Q: Are both parts electrically equivalent?

A: Yes. Both parts are DP6T, 250mA AC, 125 VAC, non-shorting (BBM) switches with identical contact material and finish. They are electrically interchangeable.

Q: Why is the MRA206-CE obsolete?

A: The MRA206-CE has been discontinued by NKK Switches. The MRAN206-CE is the active production equivalent and is the recommended replacement.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) ratings, meeting current regulatory and environmental requirements.

Q: What is the difference in packaging between the two parts?

A: The MRA206-CE was supplied in standard packaging, while the MRAN206-CE is supplied in bulk packaging. This affects procurement and handling but does not impact electrical or mechanical performance.

Q: Are the panel cutout dimensions identical?

A: Yes. Both parts require a circular 6.35mm diameter cutout and have a depth behind panel of 17.00mm, ensuring mechanical interchangeability in existing panel layouts.
