MB2011LS1W01-BB Equivalent & Substitute Parts

Part Overview

The MB2011LS1W01-BB is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 6A AC / 3A DC current rating at 125V AC / 30V DC. This component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. The switch employs panel mount rear termination with solder lug connections and epoxy sealed terminals for environmental protection.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011LS1W01-BB is determined by the following critical parameters:

Primary Electrical Compatibility Criteria:

• Circuit configuration: SPDT
• Switch function: On-Mom (momentary operation)
• AC current rating: minimum 6A
• AC voltage rating: minimum 125V
• DC current rating: minimum 3A
• DC voltage rating: minimum 30V

Mechanical Compatibility Criteria:

• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• Panel cutout diameter: 6.50mm (or compatible within mechanical tolerance)

Regulatory Compliance:

• RoHS3 compliance required
• MSL rating: 1 (Unlimited)

The identified substitute parts MBN15LS1W01-BB, MPA106F, and MPE106F meet the core electrical and mechanical requirements for direct substitution in applications previously utilizing the MB2011LS1W01-BB.

Parameter Comparison

Engineering Selection Recommendations

MPA106F and MPE106F (TE Connectivity ALCOSWITCH): Both MPA106F and MPE106F are active products meeting the electrical requirements of the MB2011LS1W01-BB with equivalent AC current and voltage ratings. Both feature ROHS3 compliance and solder lug termination. The MPE106F provides additional splash proof ingress protection. The panel cutout diameter of 6.35mm is slightly smaller than the original 6.50mm specification; mechanical compatibility must be verified for existing panel designs. Both parts demonstrate extended electrical life (50,000 cycles) compared to the original specification (25,000 cycles).

MBN15LS1W01-BB (NKK Switches): This NKK Switches alternative maintains manufacturer continuity and ROHS3 compliance. However, critical electrical and mechanical parameters are not specified in available documentation. The bushing mount configuration differs from the panel mount rear specification of the original part. This option requires complete technical specification verification before implementation.

Recommendation Priority: For direct electrical and mechanical substitution with documented specifications, MPA106F and MPE106F are the primary alternatives. MPE106F offers enhanced environmental protection through splash proof rating. MBN15LS1W01-BB requires specification confirmation from the manufacturer before selection.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F be used as direct replacements for MB2011LS1W01-BB?

A: Both MPA106F and MPE106F meet the core electrical requirements (SPDT circuit, 6A AC / 4A DC, 125V AC / 28V DC, On-Mom function, solder lug termination). The panel cutout diameter difference (6.35mm versus 6.50mm) requires mechanical verification for existing panel designs. Both are active products with ROHS3 compliance.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical specifications and mounting configuration. MPE106F includes splash proof ingress protection, providing enhanced environmental resistance. Selection depends on application environmental requirements.

Q: Why is the operating temperature range of MPA106F and MPE106F narrower than the original part?

A: The original MB2011LS1W01-BB specifies -30°C to 85°C operation, while MPA106F and MPE106F specify -20°C to 80°C. Applications requiring operation below -20°C or above 80°C must verify compatibility with the substitute parts' temperature limitations.

Q: Are there packaging considerations when switching to MPA106F or MPE106F?

A: All substitute parts are supplied in bulk packaging. Inventory availability differs: MPA106F (1578 pcs), MPE106F (1039 pcs), and MBN15LS1W01-BB (663 pcs) are currently in stock. Procurement lead times and minimum order quantities should be confirmed with suppliers.

Q: What compliance certifications apply to these substitute parts?

A: MPA106F, MPE106F, and MBN15LS1W01-BB all carry ROHS3 compliance certification. MPE106F is REACH Affected; MPA106F status is vendor undefined; MBN15LS1W01-BB is REACH Unaffected. All parts are classified under ECCN EAR99 and HTSUS 8536.50.9035.
