Equivalent & Substitute Parts for MB2085SS1W01

Part Overview

The MB2085SS1W01 is a pushbutton switch manufactured by NKK Switches, featuring DPDT (Double Pole Double Throw) circuitry with a standard panel mount configuration. This component is rated for 6A at 125V AC and 3A at 30V DC, with a plunger actuator and solder lug termination. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing system maintenance and new designs requiring compatible switching solutions.

Key Parameters

Substitute Part Grouping Explanation

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

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

Two substitute parts meet these criteria:

MBN22SS1W01 (NKK Switches) – Manufacturer-recommended substitute within the same product family, maintaining compatibility with the original specification envelope.

MPA206N (TE Connectivity ALCOSWITCH Switches) – Cross-manufacturer alternative meeting all critical electrical and mechanical parameters for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

MBN22SS1W01 is the manufacturer-recommended substitute, maintaining NKK Switches product family continuity. This part is currently in active production status with ROHS3 compliance and 829 units available in inventory.

MPA206N provides a cross-manufacturer alternative with active product status and higher electrical life rating (50,000 cycles versus 25,000 cycles). This part maintains equivalent AC electrical ratings and panel mount configuration. DC voltage rating is 28V versus the original 30V specification, and DC current rating is 4A versus 3A, both within acceptable operational margins. Panel cutout diameter is 6.35mm, which is compatible with the 6.50mm specification. Operating temperature range is -20°C to 80°C, narrower than the original -30°C to 85°C range. REACH status is affected for this part. Inventory availability is 1,470 units.

Both substitutes carry ROHS3 compliance and are suitable for applications requiring DPDT On-On switching at 6A/125V AC specifications.

Frequently Asked Questions (FAQ)

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

A: Yes, MPA206N meets all critical substitution parameters: DPDT circuit, On-On function, 6A AC rating, 125V AC rating, Panel Mount Rear configuration, and Solder Lug termination. The 6.35mm panel cutout is compatible with the 6.50mm specification. DC ratings (4A at 28V) exceed the original 3A at 30V requirement for most applications.

Q: What is the difference between the two substitute parts?

A: MBN22SS1W01 is a same-manufacturer alternative from NKK Switches. MPA206N is a cross-manufacturer solution from TE Connectivity ALCOSWITCH with higher electrical life (50,000 cycles) and improved DC current rating (4A). MPA206N has a narrower operating temperature range (-20°C to 80°C versus -30°C to 85°C).

Q: Are there any mechanical compatibility concerns with panel mounting?

A: Panel cutout diameter for MPA206N is 6.35mm compared to the original 6.50mm. This smaller diameter is compatible with the original specification. Both substitute parts maintain Panel Mount, Rear configuration with Solder Lug termination.

Q: Do the substitute parts have the same electrical life rating?

A: No. The original MB2085SS1W01 has 25,000 electrical life cycles. MPA206N has 50,000 cycles, providing extended operational life. MBN22SS1W01 electrical life is not specified in available documentation.

Q: Are both substitutes RoHS compliant?

A: Yes, both MBN22SS1W01 and MPA206N are ROHS3 compliant, matching the original part's compliance status.
