MB2011LD1W01-BA Equivalent & Substitute Parts

Part Overview

The MB2011LD1W01-BA 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-BA is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be SPDT
• Switch function must be On-Mom (momentary)
• AC current rating must be minimum 6A at 125V
• DC current rating must be minimum 3A at 30V

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 (6.35mm cutout is acceptable within mechanical tolerance)

Regulatory & Compliance Requirements:

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

The substitute parts MPA106F and MPE106F meet all electrical requirements with equal or superior ratings. Both parts are manufactured by TE Connectivity ALCOSWITCH Switches and maintain active product status, ensuring long-term availability and supply chain stability.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are qualified substitutes for the obsolete MB2011LD1W01-BA based on electrical and mechanical parameter alignment. The selection between these two active alternatives depends on application-specific environmental requirements:

MPA106F Selection Criteria:

• Applications requiring standard environmental protection
• Designs with no splash or moisture exposure requirements
• Cost-optimized procurement for standard indoor panel-mount applications

MPE106F Selection Criteria:

• Applications requiring splash-proof ingress protection
• Designs exposed to moisture, condensation, or washdown environments
• Enhanced environmental durability requirements

Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory conformance and compatibility with standard manufacturing processes. The substitute parts provide superior electrical life ratings (50,000 cycles versus 25,000 cycles), extending component reliability in high-cycle applications.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F be used as direct replacements for MB2011LD1W01-BA?

A: Yes. Both parts meet the critical electrical parameters (6A AC at 125V, minimum 3A DC), maintain identical SPDT circuit configuration and On-Mom switch function, and share compatible panel-mount rear termination with solder lug connections. Panel cutout diameter tolerance (6.35mm versus 6.50mm) is within standard mechanical acceptance for circular openings.

Q: What is the difference between MPA106F and MPE106F?

A: The primary difference is ingress protection. MPE106F provides splash-proof protection, while MPA106F offers standard environmental protection. Both parts are electrically and mechanically identical in all other specifications.

Q: Are there temperature range considerations for substitution?

A: The substitute parts operate within -20°C to 80°C, compared to the original part's -30°C to 85°C range. Applications requiring operation below -20°C or above 80°C require design review to confirm compatibility with the narrower temperature envelope.

Q: Does the panel cutout diameter difference affect mechanical fit?

A: The 0.15mm difference (6.50mm original versus 6.35mm substitute) is within standard mechanical tolerance for circular panel cutouts. No panel modification is required for substitution.

Q: What compliance certifications apply to the substitute parts?

A: Both MPA106F and MPE106F maintain ROHS3 compliance and MSL 1 (Unlimited) rating, ensuring compatibility with standard manufacturing and assembly processes. MPE106F is additionally REACH Affected; MPA106F status is Vendor Undefined.
