Equivalent & Substitute Parts for MB2085SS1W01-BH

Part Overview

The MB2085SS1W01-BH is a pushbutton switch manufactured by NKK Switches, configured as a DPDT (Double Pole Double Throw) standard panel mount switch with On-On functionality. This component is rated for 6A AC at 125V and 3A DC at 30V, featuring a gray round button actuator with solder lug termination and epoxy sealed terminals.

The MB2085SS1W01-BH is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

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

• Circuit configuration must be DPDT
• Switch function must be On-On
• AC current rating must be 6A minimum
• AC voltage rating must be 125V minimum
• DC voltage rating must be 28V minimum
• Mounting type must be Panel Mount, Rear
• Termination style must be Solder Lug
• Panel cutout diameter must accommodate 6.35mm to 6.50mm range

Two substitute parts meet these criteria: MBN22SS1W01-BH (manufacturer-recommended upgrade from NKK Switches) and MPA206N (functionally equivalent alternative from TE Connectivity ALCOSWITCH Switches).

Parameter Comparison

Engineering Selection Recommendations

MBN22SS1W01-BH is the primary substitute option. As an active product from the original manufacturer NKK Switches, it provides direct design continuity and maintains the same electrical specifications and mounting characteristics as the obsolete MB2085SS1W01-BH. This part is recommended for new designs and ongoing production requiring seamless compatibility.

MPA206N from TE Connectivity ALCOSWITCH Switches is a functionally equivalent alternative. It meets all critical electrical and mechanical parameters, with the exception of a 0.15mm reduction in panel cutout diameter (6.35mm versus 6.50mm). The MPA206N offers extended electrical life (50,000 cycles versus 25,000 cycles) and is ROHS3 compliant. However, REACH status differs from the original part. This substitute is suitable for applications where panel cutout tolerance permits the smaller diameter and where extended electrical life is beneficial.

Frequently Asked Questions (FAQ)

Q: Can MPA206N be used as a direct replacement for MB2085SS1W01-BH?

A: MPA206N is functionally equivalent for electrical operation. The panel cutout diameter differs by 0.15mm (6.35mm versus 6.50mm). Compatibility depends on panel hole tolerance. If the panel hole is sized precisely for 6.50mm, mechanical fit may be compromised. Verify panel cutout specifications before substitution.

Q: What is the difference in electrical life between the original part and MPA206N?

A: The MB2085SS1W01-BH has an electrical life rating of 25,000 cycles. The MPA206N has an electrical life rating of 50,000 cycles, providing double the rated operational cycles.

Q: Are both substitute parts RoHS3 compliant?

A: Yes, both MBN22SS1W01-BH and MPA206N are ROHS3 compliant, matching the compliance status of the original MB2085SS1W01-BH.

Q: Does REACH status affect part selection?

A: The original MB2085SS1W01-BH is REACH Unaffected. MBN22SS1W01-BH status is not specified. MPA206N is REACH Affected. For applications subject to REACH regulations, verify regulatory requirements with your compliance team before selecting MPA206N.

Q: Which substitute should I choose for new designs?

A: MBN22SS1W01-BH is the recommended choice for new designs, as it is the active product from the original manufacturer with identical specifications and mounting characteristics.
