MB2085LS1W03 Equivalent & Substitute Parts

Part Overview

The MB2085LS1W03 is a pushbutton switch manufactured by NKK Switches, featuring DPDT (Double Pole Double Throw) circuitry with an on-on switch function. This component is designed for panel mount, rear installation applications requiring 6A AC at 125V or 3A DC at 30V switching capacity. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this switch type remains the preferred solution.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2085LS1W03 is determined by the following critical parameters:

• Circuit configuration (DPDT requirement)
• Switch function (On-On operation)
• Current and voltage ratings (6A AC at 125V minimum; 3A DC at 30V minimum)
• Mounting type (Panel Mount, Rear)
• Actuator type (Plunger for Cap)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular 6.50mm Dia)
• Operating temperature range (-30°C to 85°C)
• Mechanical and electrical life specifications

The identified substitute MBN22LS1W03 from NKK Switches maintains compatibility within these defined parameters, enabling direct functional replacement in applications currently utilizing the MB2085LS1W03.

Parameter Comparison

Engineering Selection Recommendations

The MB2085LS1W03 is classified as obsolete; therefore, the MBN22LS1W03 is the recommended substitute for new procurements and system replacements. Both components are manufactured by NKK Switches and maintain identical electrical specifications (DPDT, 6A AC at 125V, 3A DC at 30V) and mechanical life ratings (100,000 cycles). Both parts are ROHS3 compliant, ensuring regulatory alignment for current manufacturing standards.

The primary distinction is product status: the MB2085LS1W03 is no longer in active production, while the MBN22LS1W03 is actively manufactured and stocked. The MBN22LS1W03 is available in bulk packaging with confirmed inventory of 681 pieces, supporting both immediate replacement needs and production planning.

Frequently Asked Questions (FAQ)

Q: Can the MBN22LS1W03 directly replace the MB2085LS1W03 in existing applications?

A: Yes. Both components share identical electrical ratings (DPDT, 6A AC at 125V, 3A DC at 30V), switch function (On-On), termination style (PC Pin), and operating temperature range (-30°C to 85°C). Mechanical and electrical life specifications are equivalent.

Q: What is the difference between panel mount and bushing mount configurations?

A: Panel mount, rear installation uses a rear-mounted bracket for panel attachment. Bushing mount uses a threaded bushing for panel installation. Both mounting methods accommodate the same 6.50mm circular panel cutout dimension. Installation method selection depends on the specific panel assembly design and available mounting hardware.

Q: Are both parts RoHS compliant?

A: Yes. Both the MB2085LS1W03 and MBN22LS1W03 are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing.

Q: Why is the MB2085LS1W03 classified as obsolete?

A: Obsolete status indicates the component is no longer manufactured by NKK Switches. The MBN22LS1W03 represents the active production equivalent, ensuring continued availability and supply chain reliability.

Q: What packaging options are available for the substitute part?

A: The MBN22LS1W03 is supplied in bulk packaging with current inventory of 681 pieces in stock.
