MRA112-CE Equivalent & Substitute Parts

Part Overview

The MRA112-CE 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 125 VAC with a 250mA current rating and features a non-shorting (BBM) contact configuration. The component is panel-mounted with through-hole termination and a knob actuator.

The MRA112-CE is classified as obsolete. Locating equivalent or substitute components is necessary for ongoing maintenance, repair, and new design implementations where this specific model is no longer readily available from primary sources or where design flexibility permits alternative selections.

Key Parameters

Substitute Part Grouping Explanation

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

• Circuit Configuration: SP12T (Single Pole, 12 Throw)
• Current Rating: 250mA AC minimum
• Voltage Rating: 125 VAC minimum
• Contact Timing: Non-Shorting (BBM)
• Mounting Type: Panel Mount, Through Hole
• Termination Style: PC Pin
• Actuator Type: Knob

The MRAN112-CE qualifies as a substitute based on compatibility across these core electrical and mechanical parameters. Both components are manufactured by NKK Switches and share the same base product family lineage, ensuring dimensional and functional alignment for direct replacement applications.

Engineering Selection Recommendations

The MRAN112-CE is designated as the manufacturer-recommended substitute for the MRA112-CE. The primary advantage of selecting MRAN112-CE is its active product status, ensuring ongoing availability and supply chain continuity. Both components originate from the same manufacturer and product family, supporting design compatibility and interchangeability in existing applications.

The MRA112-CE, classified as obsolete, presents supply constraints for new procurement. Transitioning to MRAN112-CE aligns with current component availability while maintaining electrical and mechanical specifications required for rotary switch applications in the 2 to 12 position range at 125 VAC, 250mA operation.

Frequently Asked Questions (FAQ)

Q: Can MRAN112-CE directly replace MRA112-CE in existing designs?

A: Yes. Both components are manufactured by NKK Switches and share the same base product family. The MRAN112-CE is the manufacturer-designated substitute and maintains compatibility across electrical ratings (125 VAC, 250mA), circuit configuration (SP12T), contact timing (Non-Shorting BBM), mounting type (Panel Mount, Through Hole), and termination style (PC Pin).

Q: What is the primary reason to transition from MRA112-CE to MRAN112-CE?

A: The MRA112-CE is obsolete, limiting availability for new procurement and ongoing supply. The MRAN112-CE maintains active product status, ensuring reliable sourcing and supply chain stability.

Q: Are there any packaging differences between these components?

A: Both components are supplied in bulk packaging. No packaging format changes are required for substitution.

Q: What electrical parameters must remain consistent for substitution?

A: Substitution requires matching the following parameters: 125 VAC voltage rating, 250mA AC current rating, SP12T circuit configuration, Non-Shorting (BBM) contact timing, and PC Pin termination style.

Q: Is the MRAN112-CE RoHS compliant?

A: Compliance information for MRAN112-CE is not provided in the available technical data. Verify RoHS and regulatory compliance status with the manufacturer or authorized distributor before final component selection.
