MB2011SD1W01-CC Equivalent & Substitute Parts

Part Overview

The MB2011SD1W01-CC 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 functionally equivalent alternatives for ongoing design support and procurement continuity. The switch employs panel mount rear termination with solder lug connections and epoxy sealed terminals suitable for industrial control applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SD1W01-CC is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Momentary
• AC current rating: 6A minimum
• AC voltage rating: 125V minimum
• DC voltage rating: 28V or higher
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• Panel cutout diameter: 6.35mm or 6.50mm (compatible with standard panel preparations)

Compliance Requirements:

• RoHS3 compliance mandatory
• MSL rating 1 (Unlimited) preferred for storage stability

The substitute parts MPA106F and MPE106F satisfy these criteria. Both 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 MB2011SD1W01-CC based on electrical parameter compatibility and regulatory compliance. Selection between the two TE Connectivity alternatives depends on application environmental requirements:

MPA106F Selection Criteria:

• Standard industrial control applications without splash or moisture exposure
• Active product status ensures procurement availability
• ROHS3 compliant with vendor-undefined REACH status

MPE106F Selection Criteria:

• Applications requiring splash-proof ingress protection
• Active product status with extended electrical life (50,000 cycles vs. 25,000 cycles)
• REACH Affected designation indicates full regulatory documentation availability
• Recommended for environments with potential liquid exposure or washdown requirements

Both substitutes provide superior electrical life ratings (50,000 cycles) compared to the original component (25,000 cycles), supporting extended service intervals in production equipment.

Frequently Asked Questions (FAQ)

Q: Can MPA106F and MPE106F be used interchangeably with MB2011SD1W01-CC?

A: Both parts meet the electrical requirements (6A AC at 125V, SPDT On-Momentary function, solder lug termination). Panel cutout diameter differs slightly (6.35mm vs. 6.50mm), requiring verification of existing panel preparations. MPE106F adds splash-proof protection not present in the original or MPA106F.

Q: What is the impact of the 0.15mm panel cutout diameter difference?

A: The MB2011SD1W01-CC requires a 6.50mm circular cutout, while both TE Connectivity substitutes require 6.35mm. Existing panels prepared for 6.50mm cutouts may require modification or use of panel adapters. New designs should accommodate the 6.35mm standard.

Q: Are there temperature range limitations with the substitute parts?

A: The original MB2011SD1W01-CC operates from -30°C to 85°C, while MPA106F and MPE106F operate from -20°C to 80°C. Applications requiring operation below -20°C or above 80°C must retain the original component or identify alternative solutions.

Q: What is the significance of the higher DC current rating in the substitutes?

A: MPA106F and MPE106F provide 4A DC versus 3A DC for the original part. This represents improved capability for DC-switched loads and does not create compatibility issues in applications designed for 3A DC operation.

Q: Which substitute is recommended for new designs?

A: MPE106F is recommended for new designs due to active product status, splash-proof ingress protection, and extended electrical life (50,000 cycles). MPA106F serves as an alternative for cost-sensitive applications without environmental protection requirements.

Q: Are both substitutes RoHS3 compliant?

A: Yes, both MPA106F and MPE106F are ROHS3 compliant, matching the original component's regulatory status and supporting lead-free manufacturing requirements.
