MRA112-A Equivalent & Substitute Parts

Part Overview

The MRA112-A is a rotary switch manufactured by NKK Switches, classified as a 2-12 position SP12T switch rated for 250mA AC at 125 VAC. This component features a panel mount, through-hole configuration with a knob actuator and non-shorting (BBM) contact timing. The MRA112-A is currently listed as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MRA112-A is determined by the following critical parameters that must remain consistent:

• Circuit Configuration: SP12T (single pole, 12 throw) electrical topology
• Current Rating: 250mA AC minimum
• Voltage Rating: 125 VAC minimum
• Contact Timing: Non-Shorting (BBM) operation
• Mounting Interface: Panel mount, through-hole with PC pin termination
• Panel Cutout Compatibility: Circular 6.35mm diameter opening
• Contact Material & Finish: Copper with silver finish for electrical performance

The MRAN112-A from NKK Switches meets these substitution criteria as a functionally equivalent component. Both parts share the same manufacturer, electrical ratings, contact configuration, and mechanical mounting requirements.

Parameter Comparison

Engineering Selection Recommendations

The MRAN112-A is identified as the manufacturer-recommended substitute for the obsolete MRA112-A. Both components are manufactured by NKK Switches and share identical HTSUS and ECCN classifications, confirming regulatory alignment. The MRAN112-A carries Active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete MRA112-A.

Both parts maintain ROHS3 compliance, satisfying environmental and regulatory requirements for electronic component deployment. The transition from MRA112-A to MRAN112-A does not introduce compliance risks or regulatory conflicts.

Frequently Asked Questions (FAQ)

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

A: The MRAN112-A is the manufacturer-recommended substitute. Both components are from NKK Switches and share the same regulatory classifications (HTSUS, ECCN). Verify that the specific electrical ratings (current, voltage, circuit configuration) match your application requirements before implementation.

Q: What is the primary reason for substitution?

A: The MRA112-A is obsolete. The MRAN112-A is an active product from the same manufacturer, providing continued availability and supply chain support.

Q: Are there packaging differences between these parts?

A: The MRA112-A is specified with standard packaging, while MRAN112-A is supplied in Bulk packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MRA112-A and MRAN112-A are ROHS3 compliant and carry EAR99 ECCN classification, ensuring equivalent regulatory status.

Q: What parameters must remain consistent for substitution?

A: Circuit configuration (SP12T), current rating (250mA AC), voltage rating (125 VAC), contact timing (non-shorting BBM), mounting type (panel mount, through-hole), and termination style (PC pin) must all be verified as equivalent in any substitute component.
