MB2011LS4W01 Equivalent & Substitute Parts

Part Overview

The MB2011LS4W01 is a pushbutton switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 6A at 125V AC and 3A at 30V DC. Manufactured by NKK Switches in the MB2000 series, this component features a plunger actuator with solder lug termination and panel mount rear configuration. The product is currently obsolete, necessitating identification of functionally equivalent active alternatives to maintain design continuity and ensure supply chain availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MB2011LS4W01 are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Electrical Parameters: Circuit configuration (SPDT), switch function (On-Momentary), AC voltage rating (125V minimum), and AC current rating (6A minimum). These parameters define the core electrical functionality.

Mechanical Parameters: Panel mount rear configuration, plunger actuator type, and solder lug termination ensure physical and electrical interface compatibility.

Compliance Parameters: ROHS3 compliance and MSL rating (1 - Unlimited) are required for regulatory and environmental compatibility.

The identified substitute parts MPA106F and MPE106F meet these core criteria. Both are active products from TE Connectivity ALCOSWITCH Switches, maintaining SPDT circuit configuration, 6A AC rating at 125V, plunger actuator, solder lug termination, and panel mount rear mounting. Both are ROHS3 compliant with MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are suitable substitutes for the obsolete MB2011LS4W01 based on electrical and mechanical parameter alignment. Both substitute parts are active products with current manufacturing support, ensuring long-term availability.

MPA106F provides direct electrical and mechanical compatibility with the main part. This option is appropriate for standard applications where the operating environment does not require enhanced ingress protection.

MPE106F offers the same electrical and mechanical compatibility as MPA106F with the additional feature of splash proof ingress protection. This option is suitable for applications exposed to moisture or liquid splash conditions. MPE106F carries REACH Affected status, requiring compliance verification for applications subject to REACH regulations.

Both substitute parts operate within narrower temperature ranges (-20°C to 80°C) compared to the main part (-30°C to 85°C). Panel cutout dimensions differ slightly (6.35mm versus 6.50mm), requiring mechanical design verification for panel mounting compatibility. Both substitute parts provide extended electrical life (50,000 cycles versus 25,000 cycles), representing improved durability.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F be used as direct replacements for MB2011LS4W01?

A: Both parts meet the core electrical requirements (SPDT circuit, 6A at 125V AC, On-Momentary function) and mechanical interface specifications (panel mount rear, plunger actuator, solder lug termination). Panel cutout diameter differences (6.35mm versus 6.50mm) require mechanical design review to confirm mounting compatibility.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts are electrically and mechanically identical. MPE106F includes splash proof ingress protection, making it suitable for environments with moisture or liquid exposure. MPA106F is specified for standard environmental conditions without enhanced ingress protection.

Q: Are there temperature range limitations when substituting these parts?

A: The substitute parts operate within -20°C to 80°C, compared to the main part's -30°C to 85°C range. Applications requiring operation below -20°C or above 80°C require alternative component selection.

Q: Do the substitute parts have improved electrical life?

A: Yes. Both MPA106F and MPE106F are rated for 50,000 electrical cycles, compared to 25,000 cycles for MB2011LS4W01. This represents a 2x improvement in electrical life expectancy.

Q: What compliance certifications apply to these substitute parts?

A: All three parts are ROHS3 compliant with MSL 1 (Unlimited) rating. MPE106F carries REACH Affected status, requiring compliance verification for applications subject to REACH regulations. MPA106F has Vendor Undefined REACH status.

Q: Are there DC current rating differences?

A: Yes. MB2011LS4W01 is rated for 3A DC at 30V. Both substitute parts are rated for 4A DC at 28V. Applications operating at DC levels should confirm these parameter differences are acceptable for the intended circuit.
