MB2011SS1W01-CB Equivalent & Substitute Parts

Part Overview

The MB2011SS1W01-CB is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with a rated capacity of 6A at 125V AC and 3A at 30V DC. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for new designs and ongoing production requirements. The switch employs a round button actuator with solder lug termination and is rated for 100,000 mechanical cycles and 25,000 electrical cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SS1W01-CB is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration (SPDT)
• Switch function (On-Momentary)
• AC current rating minimum of 6A
• AC voltage rating minimum of 125V
• Panel mount, rear configuration
• Solder lug termination
• Panel cutout diameter compatibility (6.50mm nominal)

Secondary Compatibility Criteria:

• DC current rating (minimum 3A acceptable)
• DC voltage rating (minimum 28V acceptable)
• Operating temperature range overlap
• RoHS3 compliance
• Moisture sensitivity level (MSL 1)

The identified substitutes MPA106F and MPE106F from TE Connectivity ALCOSWITCH Switches meet the primary criteria with panel cutout diameter of 6.35mm (within acceptable tolerance for panel mount applications). MBN15SS1W01-CB represents a manufacturer-recommended alternative within the NKK Switches product line.

Parameter Comparison

Engineering Selection Recommendations

MBN15SS1W01-CB (NKK Switches): This part is the manufacturer-recommended substitute and maintains identical electrical ratings and operating temperature range to the obsolete MB2011SS1W01-CB. Active product status ensures long-term availability and supply chain continuity. Selection of this alternative eliminates cross-manufacturer qualification requirements.

MPA106F (TE Connectivity ALCOSWITCH Switches): This substitute meets all primary electrical and mechanical compatibility criteria with equivalent AC ratings and solder lug termination. The 6.35mm panel cutout diameter requires panel modification or adapter consideration. DC current rating of 4A exceeds the original 3A specification. Electrical life rating of 50,000 cycles provides extended operational durability compared to the original 25,000 cycles. ROHS3 compliance is confirmed; REACH status is vendor-undefined.

MPE106F (TE Connectivity ALCOSWITCH Switches): This substitute provides identical electrical performance to MPA106F with the addition of splash-proof ingress protection. The 6.35mm panel cutout diameter requires the same panel accommodation as MPA106F. REACH Affected status indicates regulatory compliance documentation is available. Electrical life of 50,000 cycles and 4A DC current rating provide performance margins above original specifications.

All substitutes maintain ROHS3 compliance and MSL 1 rating, supporting deployment in standard manufacturing environments without moisture sensitivity constraints.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F be used as direct drop-in replacements for MB2011SS1W01-CB?

A: Electrical compatibility is confirmed for both TE Connectivity alternatives. Panel cutout diameter differs (6.35mm versus 6.50mm), requiring panel modification or mechanical adapter. Solder lug termination and SPDT On-Momentary function are identical.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical ratings, current capacity, voltage ratings, and electrical life specifications. MPE106F includes splash-proof ingress protection; MPA106F does not. MPE106F has REACH Affected status; MPA106F status is vendor-undefined.

Q: Is MBN15SS1W01-CB the preferred substitute?

A: MBN15SS1W01-CB is the manufacturer-recommended alternative from NKK Switches, maintaining identical panel cutout diameter (6.50mm) and operating temperature range (-30°C to 85°C). No mechanical modification is required for panel integration.

Q: What are the DC voltage and current differences between the original and substitutes?

A: MB2011SS1W01-CB is rated 3A at 30V DC. MPA106F and MPE106F are rated 4A at 28V DC. The 1A increase in DC current capacity and 2V reduction in DC voltage rating do not prevent substitution in applications operating within the original 3A and 30V specifications.

Q: Are all substitutes RoHS3 compliant?

A: Yes. MB2011SS1W01-CB, MBN15SS1W01-CB, MPA106F, and MPE106F are all ROHS3 compliant. All parts carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What mechanical life rating should be expected from substitute parts?

A: MBN15SS1W01-CB maintains the original 100,000 cycle mechanical life specification. Mechanical life data for MPA106F and MPE106F is not provided in available documentation.
