MB2011SD3W01-BF Equivalent & Substitute Parts

Part Overview

The MB2011SD3W01-BF 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 panel-mount rear component utilizes a green round button actuator with solder lug termination and IP67 ingress protection. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations where the original component is no longer available through standard procurement channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SD3W01-BF is determined by strict alignment with the following electrical and mechanical parameters:

Critical Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom
• AC current rating: 6A minimum
• AC voltage rating: 125V minimum
• DC voltage rating: 28V minimum (original specifies 30V)
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• Panel cutout diameter: 6.35mm to 6.50mm (circular)

Acceptable Variance:

• DC current rating: Original 3A; substitutes rated 4A are acceptable (higher rating)
• Operating temperature: Original -30°C to 85°C; substitutes with -20°C to 80°C are acceptable (narrower range)
• Electrical life: Original 25,000 cycles; substitutes with 50,000 cycles are acceptable (higher rating)
• Ingress protection: Original IP67; substitutes with Splash Proof or IP67 are acceptable

Substitute Parts Identified:

1. MBN15SD3W01-BF (NKK Switches) – Manufacturer-recommended direct substitute. Active product status. Bushing mount miniature pushbutton configuration.

2. MPA106F (TE Connectivity ALCOSWITCH Switches) – Functionally equivalent SPDT pushbutton switch. Active product status. Meets all critical electrical parameters with 4A DC rating and 28V DC voltage rating.

3. MPE106F (TE Connectivity ALCOSWITCH Switches) – Functionally equivalent SPDT pushbutton switch with enhanced ingress protection (Splash Proof). Active product status. Meets all critical electrical parameters with 4A DC rating and 28V DC voltage rating.

Parameter Comparison

Engineering Selection Recommendations

MBN15SD3W01-BF is the primary substitute option. As an NKK Switches product with active status and manufacturer recommendation, this part maintains supply chain continuity with the original manufacturer. Selection of this part eliminates cross-manufacturer compatibility concerns.

MPA106F and MPE106F are secondary substitute options from TE Connectivity ALCOSWITCH Switches. Both parts are active products with ROHS3 compliance. These substitutes meet all critical electrical parameters (6A AC at 125V, 4A DC at 28V) and maintain identical circuit configuration and switch function. The higher DC current rating (4A versus 3A) and extended electrical life (50,000 cycles versus 25,000 cycles) provide operational margin. MPE106F offers enhanced ingress protection (Splash Proof) compared to the original IP67 specification. Panel cutout diameter variance (6.35mm versus 6.50mm) requires mechanical verification for panel compatibility.

Selection between these three substitutes depends on supply availability, cost considerations, and specific application requirements regarding ingress protection and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can MPA106F and MPE106F be used interchangeably with MB2011SD3W01-BF?

A: Yes, both parts meet the critical electrical parameters: SPDT circuit, On-Mom function, 6A AC at 125V, and 4A DC at 28V. The primary consideration is panel cutout diameter. The original part specifies 6.50mm; the TE Connectivity substitutes specify 6.35mm. Mechanical verification of panel compatibility is required before implementation.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical ratings and circuit configuration. MPE106F provides enhanced ingress protection (Splash Proof) compared to MPA106F (ingress protection not specified). Selection depends on environmental exposure requirements in the target application.

Q: Is MBN15SD3W01-BF a direct replacement?

A: MBN15SD3W01-BF is the manufacturer-recommended substitute from NKK Switches. However, detailed electrical and mechanical specifications are not provided in the available data. Consultation with NKK Switches technical documentation is required to confirm full compatibility with the original MB2011SD3W01-BF.

Q: Are all substitute parts RoHS3 compliant?

A: MPA106F and MPE106F are confirmed ROHS3 compliant. MBN15SD3W01-BF RoHS status is not specified in available data. Verification with the manufacturer is recommended for regulatory compliance documentation.

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

A: The original MB2011SD3W01-BF specifies 6.50mm; TE Connectivity substitutes specify 6.35mm. This 0.15mm difference is within typical mechanical tolerance but requires physical verification against the panel cutout dimensions in your specific application to ensure proper fit and seating.

Q: Can I use these substitutes in applications requiring the full -30°C to 85°C temperature range?

A: MPA106F and MPE106F are rated -20°C to 80°C, which is narrower than the original -30°C to 85°C range. If your application requires operation below -20°C or above 80°C, these substitutes are not suitable. MBN15SD3W01-BF operating temperature is not specified; manufacturer consultation is required.
