MB2085SS1W01-CC Equivalent & Substitute Parts

Part Overview

The MB2085SS1W01-CC is a pushbutton switch manufactured by NKK Switches, featuring DPDT (Double Pole Double Throw) circuitry with 6A AC and 3A DC current ratings at 125V AC and 30V DC respectively. This component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. The switch employs panel mount rear termination with solder lug connections and epoxy sealed terminals, suitable for applications requiring reliable on-on switching functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2085SS1W01-CC is determined by the following critical parameters:

• Circuit Configuration: DPDT topology required for functional equivalence
• Switch Function: On-On operation mandatory
• Current Rating: Minimum 6A AC capability; DC rating of 3A or higher acceptable
• Voltage Rating: Minimum 125V AC and 30V DC required
• Mounting Type: Panel mount rear configuration with solder lug termination
• Actuator Type: Round button configuration
• Panel Cutout Compatibility: Circular aperture within acceptable tolerance range (6.35mm to 6.50mm)
• Compliance: ROHS3 compliance required

The identified substitute parts meet these criteria while maintaining active product status, ensuring availability and ongoing manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

MBN22SS1W01-CC (NKK Switches): This part represents the manufacturer-recommended direct replacement, maintaining NKK Switches sourcing continuity. Active product status ensures long-term availability and supply chain stability. Detailed electrical specifications are not provided in available documentation; verification with the manufacturer is necessary prior to design implementation.

8261S1HZQE2, 8261SHZQE2, 8261SHZQE4 (C&K): These C&K alternatives from the 8060 series satisfy all critical substitution parameters. All three variants are active products with enhanced electrical life ratings (50,000 cycles versus 25,000 cycles). The 8261SHZQE2 and 8261SHZQE4 differ only in actuator cap color (black and orange respectively). Panel cutout diameter is 6.35mm, requiring verification of mechanical fit within existing panel apertures designed for 6.50mm. REACH status indicates regulatory impact in specific jurisdictions.

MPA206N (TE Connectivity ALCOSWITCH): This MPA series switch meets voltage and current requirements with 6A AC and 4A DC ratings. The actuator configuration differs (plunger for cap versus round button), which may affect user interface ergonomics and panel aesthetics. Operating temperature range (-20°C to 80°C) is narrower than the original specification. Active product status and ROHS3 compliance support long-term design viability.

Frequently Asked Questions (FAQ)

Q: Can the MB2085SS1W01-CC be directly replaced with any of these substitutes?

A: Direct replacement depends on application-specific requirements. All identified substitutes maintain DPDT on-on functionality with 6A AC capability. Verify panel cutout diameter compatibility (original 6.50mm versus substitute 6.35mm), operating temperature range requirements, and actuator type preferences before implementation.

Q: What is the primary difference between the C&K 8261 series variants?

A: The 8261S1HZQE2, 8261SHZQE2, and 8261SHZQE4 are electrically identical. Differentiation is based on packaging (tray versus bulk) and actuator cap color (black for 8261S1HZQE2 and 8261SHZQE2; orange for 8261SHZQE4). Electrical life, voltage ratings, and current ratings are equivalent across all three variants.

Q: Does the panel cutout diameter difference affect substitution feasibility?

A: The 0.15mm reduction from 6.50mm to 6.35mm is within typical manufacturing tolerances for panel apertures. However, verify existing panel tooling and mechanical drawings to confirm compatibility. Panels designed with tight tolerances may require modification.

Q: Are there compliance considerations when substituting these parts?

A: All substitute parts maintain ROHS3 compliance. C&K parts indicate REACH affected status, requiring verification of regulatory requirements in target markets. TE Connectivity MPA206N is REACH affected. Confirm compliance obligations for your specific application and geographic region.

Q: What is the significance of electrical life rating differences?

A: The original MB2085SS1W01-CC specifies 25,000 electrical life cycles. C&K substitutes provide 50,000 cycles, and TE Connectivity MPA206N provides 50,000 cycles. Higher electrical life ratings indicate extended component durability under switching stress, beneficial for high-cycle applications.

Q: How does the MPA206N actuator type differ from the original?

A: The MB2085SS1W01-CC uses a round button actuator, while the MPA206N employs a plunger for cap configuration. This affects tactile feedback, panel presentation, and potential cap customization options. Evaluate user interface requirements and aesthetic considerations for your application.
