Equivalent & Substitute Parts for MB2011SS1W01-CE

Part Overview

The MB2011SS1W01-CE is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with a rated capacity of 6A at 125V AC and 3A at 30V DC. This component is a panel-mount, rear-termination switch with a round yellow button actuator and solder lug connections. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SS1W01-CE is determined by the following critical parameters:

Primary Matching Criteria:

• Circuit configuration (SPDT)
• Switch function (On-Momentary)
• AC voltage rating (125V minimum)
• AC current rating (6A minimum)
• Mounting type (Panel Mount, Rear)
• Termination style (Solder Lug)
• Panel cutout compatibility (circular, approximately 6.35mm to 6.50mm diameter)

Secondary Compliance Criteria:

• RoHS3 compliance
• Moisture Sensitivity Level (MSL 1)
• Operating temperature range overlap

The substitute parts identified—MBN15SS1W01-CE, MPA106F, and MPE106F—meet the primary electrical and mechanical requirements for direct substitution in applications requiring SPDT pushbutton switches with 6A/125V AC ratings and rear-panel mounting with solder lug termination.

Parameter Comparison

Engineering Selection Recommendations

MPA106F and MPE106F (TE Connectivity ALCOSWITCH) are the primary substitutes for the obsolete MB2011SS1W01-CE. Both parts are active products with confirmed ROHS3 compliance and meet the electrical requirements of 6A/125V AC operation. The TE Connectivity parts offer extended electrical life (50,000 cycles versus 25,000 cycles) and are currently in production with established supply chains.

MPE106F provides additional environmental protection through splash-proof ingress rating, making it suitable for applications requiring enhanced moisture resistance.

MBN15SS1W01-CE (NKK Switches) maintains manufacturer continuity within the NKK product line and is an active product. However, detailed electrical specifications are not provided in the available data, requiring direct confirmation with the manufacturer for complete parameter validation before selection.

The 6.35mm panel cutout diameter of the TE Connectivity substitutes is compatible with the 6.50mm cutout of the original part, as the difference falls within standard mechanical tolerance ranges for panel-mount switch installations.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F be used as direct replacements for MB2011SS1W01-CE?

A: Yes. Both parts meet the critical electrical parameters: SPDT circuit, 6A/125V AC rating, on-momentary function, panel-mount rear termination with solder lugs. The 6.35mm cutout diameter is mechanically compatible with the original 6.50mm specification.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical ratings and core specifications. MPE106F includes splash-proof ingress protection, making it suitable for applications with moisture exposure. MPA106F lacks specified ingress protection. Selection depends on environmental requirements.

Q: Why is the operating temperature range of the TE Connectivity substitutes (-20°C to 80°C) narrower than the original (-30°C to 85°C)?

A: The TE Connectivity parts have a reduced temperature operating window. Applications requiring operation below -20°C or above 80°C must confirm compatibility with the substitute part specifications or consider alternative solutions.

Q: Are MPA106F and MPE106F RoHS3 compliant?

A: Yes. Both parts carry ROHS3 compliance certification, matching the compliance status of the original MB2011SS1W01-CE.

Q: What is the inventory status of these substitute parts?

A: MPA106F has 1,578 units in stock, and MPE106F has 1,039 units in stock. MBN15SS1W01-CE has 829 units available. All substitutes are currently in production and available for procurement.

Q: Does the higher electrical life rating (50,000 cycles) of the TE Connectivity parts affect compatibility?

A: No. Higher electrical life is a performance advantage and does not affect functional compatibility. The original part's 25,000-cycle rating is a minimum threshold; substitutes with higher ratings are fully compatible.
