MB2011LD1W01-BC Equivalent & Substitute Parts

Part Overview

The MB2011LD1W01-BC is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 6A AC and 3A DC current ratings at 125V AC and 30V DC respectively. This component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain electrical performance specifications and mechanical compatibility within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011LD1W01-BC is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be SPDT
• Switch function must be On-Mom
• AC voltage rating must support 125V minimum
• AC current rating must support 6A minimum
• DC voltage rating must support 30V minimum
• DC current rating must support 3A minimum

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Rear
• Termination style must be Solder Lug
• Panel cutout diameter must accommodate 6.50mm circular opening

Regulatory & Environmental Requirements:

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

The substitute parts MPA106F and MPE106F meet the core electrical circuit requirements (SPDT, On-Mom function) and maintain mechanical compatibility through panel mount rear configuration with solder lug termination. Both parts are manufactured by TE Connectivity ALCOSWITCH Switches and carry active product status with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are qualified substitutes for the obsolete MB2011LD1W01-BC based on electrical and mechanical parameter alignment. Selection between the two active alternatives should consider the following factors:

MPA106F Selection Criteria:

• Standard ingress protection level
• Active product status with established supply chain
• ROHS3 compliant with MSL 1 rating
• Electrical life rating of 50,000 cycles exceeds original specification

MPE106F Selection Criteria:

• Splash Proof ingress protection provides enhanced environmental protection
• Active product status with established supply chain
• ROHS3 compliant with MSL 1 rating
• REACH Affected status requires compliance verification in regulated markets
• Electrical life rating of 50,000 cycles exceeds original specification

Both substitutes provide superior electrical life performance (50,000 cycles versus 25,000 cycles) and maintain full compliance with RoHS3 and MSL requirements. Panel cutout diameter reduction from 6.50mm to 6.35mm requires mechanical panel modification assessment. DC voltage rating reduction from 30V to 28V is acceptable for applications operating at or below 28V DC.

Frequently Asked Questions (FAQ)

Q: Can MPA106F and MPE106F be used interchangeably with MB2011LD1W01-BC?

A: Both parts meet the core electrical requirements (SPDT circuit, On-Mom function, 6A AC, 125V AC) and mechanical mounting specifications (Panel Mount Rear, Solder Lug termination). Panel cutout diameter differs by 0.15mm (6.50mm to 6.35mm), requiring mechanical panel assessment. DC voltage rating is 28V versus 30V original specification.

Q: What is the impact of the panel cutout diameter difference?

A: The substitute parts require a 6.35mm circular panel cutout versus the original 6.50mm specification. Existing panel tooling designed for 6.50mm diameter will require modification or replacement to accommodate the smaller 6.35mm opening.

Q: Are there differences in operating temperature ranges?

A: The original MB2011LD1W01-BC operates from -30°C to 85°C. Both substitute parts operate from -20°C to 80°C. Applications requiring operation below -20°C or above 80°C are outside the substitute part specifications.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical specifications and mechanical mounting. MPE106F provides Splash Proof ingress protection, while MPA106F does not specify ingress protection. MPE106F carries REACH Affected status, requiring compliance verification in regulated markets. MPA106F REACH status is Vendor Undefined.

Q: Do the substitute parts maintain RoHS3 compliance?

A: Both MPA106F and MPE106F are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original part's compliance profile.

Q: What is the electrical life improvement in substitute parts?

A: The original MB2011LD1W01-BC specifies 25,000 electrical cycles. Both MPA106F and MPE106F provide 50,000 electrical cycles, representing a 100% improvement in rated electrical life.
