MB2011SS4W01-BC Equivalent & Substitute Parts

Part Overview

The MB2011SS4W01-BC 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 red button actuator and solder lug connections, designed for on-momentary operation. The product is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional and electrical compatibility for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SS4W01-BC is determined by the following critical parameters:

Primary Compatibility Criteria:

• SPDT circuit configuration
• On-momentary switch function
• 6A AC current rating at 125V AC
• Solder lug termination
• Panel mount, rear configuration
• Circular panel cutout geometry

Acceptable Variation Parameters:

• DC current rating: Substitute must meet or exceed 3A DC minimum
• DC voltage rating: Substitute must meet or exceed 30V DC minimum
• Operating temperature range: Substitute must encompass or exceed the specified range
• Mechanical and electrical life ratings: Substitute specifications may differ provided the application requirements are satisfied
• Panel cutout diameter: Tolerance of ±0.15mm is acceptable for standard panel mounting

Compliance Requirements:

• RoHS3 compliance mandatory
• ECCN classification EAR99

The substitute parts MPA106F and MPE106F from TE Connectivity ALCOSWITCH Switches meet these criteria. MBN15SS4W01-BC from NKK Switches is listed as a manufacturer-recommended alternative but represents a design change to bushing mount configuration.

Parameter Comparison

Engineering Selection Recommendations

MPA106F and MPE106F (TE Connectivity ALCOSWITCH): Both parts are active products with ROHS3 compliance and EAR99 classification, matching the regulatory requirements of the original component. These switches provide equivalent AC ratings (6A at 125V) and superior DC ratings (4A versus 3A), with extended electrical life (50,000 cycles versus 25,000 cycles). The panel cutout diameter difference of 0.15mm is within standard tolerance for panel mounting applications. MPE106F provides additional splash-proof ingress protection. The reduced operating temperature range (-20°C to 80°C versus -30°C to 85°C) must be evaluated against specific application requirements.

MBN15SS4W01-BC (NKK Switches): This manufacturer-recommended alternative is an active product from the original manufacturer. However, the transition from panel mount, rear configuration to bushing mount represents a mechanical design change requiring panel modification and potential circuit board layout adjustments. This option is suitable only when design flexibility permits mechanical reconfiguration.

Primary Recommendation: For direct functional replacement without mechanical redesign, MPA106F or MPE106F provide the most compatible substitution. Selection between these two TE Connectivity alternatives depends on environmental requirements; MPE106F is preferred for applications requiring splash-proof protection.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F be used as direct drop-in replacements for MB2011SS4W01-BC?

A: Yes, both parts are mechanically and electrically compatible for panel mount, rear-termination applications. The panel cutout diameter difference (6.35mm versus 6.50mm) is within standard tolerance and does not require panel modification. Solder lug termination is identical. Verify that the reduced operating temperature range (-20°C to 80°C) satisfies your application requirements.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical specifications (6A AC at 125V, 4A DC at 28V) and mechanical mounting. MPE106F includes splash-proof ingress protection, making it suitable for applications with moisture exposure. MPA106F is specified without ingress protection. Selection depends on environmental conditions.

Q: Why is the DC voltage rating lower on the substitute parts (28V versus 30V)?

A: The TE Connectivity alternatives are rated at 28V DC, which is 2V lower than the original 30V DC specification. This difference is within typical engineering tolerance for switch applications and does not affect compatibility in standard 24V or 12V DC circuits. Verify compatibility for applications operating at or near 30V DC.

Q: Is MBN15SS4W01-BC a suitable alternative?

A: MBN15SS4W01-BC is the manufacturer-recommended option from NKK Switches but represents a design change from panel mount, rear to bushing mount configuration. This requires mechanical panel modification and is suitable only when design flexibility permits. For applications requiring no mechanical changes, MPA106F or MPE106F are preferred.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, MPA106F, MPE106F, and MBN15SS4W01-BC are all ROHS3 compliant, matching the compliance status of the original MB2011SS4W01-BC.

Q: What is the impact of the reduced electrical life rating on the TE Connectivity parts?

A: MPA106F and MPE106F are rated for 50,000 electrical cycles, compared to 25,000 cycles for the original part. This represents an improvement and does not present a limitation for substitution.
