MB2011SD3A01 Equivalent & Substitute Parts

Part Overview

The MB2011SD3A01 is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 6A AC / 3A DC current rating and 125V AC / 30V DC voltage rating. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations. The switch employs panel mount rear termination with solder lug connections and IP67 ingress protection suitable for sealed enclosure applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SD3A01 is determined by the following critical parameters: circuit configuration (SPDT), switch function (On-Mom), current and voltage ratings, mounting type (panel mount rear), termination style (solder lug), and panel cutout dimensions. Parts meeting these specifications are classified as direct equivalents. Parts with reduced current or voltage ratings, or different panel cutout dimensions, are classified as functional alternatives with application-specific limitations.

Direct Equivalents (identical electrical and mechanical specifications):

• MB2011SD3W01 (NKK Switches)
• MPA106F (TE Connectivity ALCOSWITCH)
• MPE106F (TE Connectivity ALCOSWITCH)

Functional Alternative (reduced current rating, different panel cutout):

• 700ASP7B10M1QE (E-Switch)

Parameter Comparison

Engineering Selection Recommendations

MB2011SD3W01 is the primary equivalent for direct replacement. Both parts share identical electrical ratings (6A AC / 3A DC, 125V AC / 30V DC), mechanical specifications (6.50mm panel cutout), and operating temperature range (-30°C to 85°C). Both are ROHS3 compliant and obsolete status. The only difference is packaging (tape vs. bulk), which does not affect functional compatibility.

MPA106F and MPE106F are active production alternatives from TE Connectivity ALCOSWITCH. Both maintain 6A AC current rating and 125V AC voltage rating. DC current rating increases to 4A, and DC voltage rating reduces to 28V. Panel cutout diameter is 6.35mm, requiring mechanical redesign of panel mounting. Operating temperature range narrows to -20°C to 80°C. Electrical life extends to 50,000 cycles. Both are ROHS3 compliant. MPE106F provides splash proof ingress protection versus unspecified protection for MPA106F.

700ASP7B10M1QE is a functional alternative with reduced AC current rating (3A vs. 6A). This part is suitable only for applications where AC current demand does not exceed 3A. Panel cutout diameter is 6.35mm. This is the only active production part from the substitute list and offers extended electrical life (50,000 cycles). ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can MB2011SD3W01 be used as a direct replacement for MB2011SD3A01?

A: Yes. Both parts are electrically and mechanically identical with matching current ratings (6A AC / 3A DC), voltage ratings (125V AC / 30V DC), panel cutout diameter (6.50mm), and operating temperature range (-30°C to 85°C). Packaging difference (tape vs. bulk) does not affect functionality.

Q: What are the limitations of using 700ASP7B10M1QE as a substitute?

A: The 700ASP7B10M1QE has reduced AC current rating of 3A compared to the original 6A specification. This part is suitable only for applications with AC current requirements not exceeding 3A. Additionally, the panel cutout diameter is 6.35mm versus 6.50mm, requiring mechanical panel modification. DC current and voltage ratings are compatible (3A / 28V).

Q: Are MPA106F and MPE106F interchangeable with MB2011SD3A01?

A: Both parts maintain the critical 6A AC current and 125V AC voltage ratings. However, they differ in three areas: panel cutout diameter (6.35mm vs. 6.50mm), operating temperature range (-20°C to 80°C vs. -30°C to 85°C), and DC voltage rating (28V vs. 30V). These differences require evaluation against specific application requirements. Both are active production parts with ROHS3 compliance.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical ratings and mechanical specifications. The primary difference is ingress protection: MPE106F provides splash proof protection, while MPA106F ingress protection is not specified. For sealed enclosure applications requiring IP67 equivalent protection, MPE106F is the preferred choice.

Q: Why is panel cutout diameter important for substitution?

A: Panel cutout diameter determines physical mounting compatibility. The original MB2011SD3A01 requires a 6.50mm circular cutout. Substitute parts with 6.35mm cutout diameter (700ASP7B10M1QE, MPA106F, MPE106F) will not fit existing panel openings without mechanical modification or adapter hardware.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. MB2011SD3A01, MB2011SD3W01, 700ASP7B10M1QE, MPA106F, and MPE106F are all ROHS3 compliant, meeting current environmental and hazardous substance restrictions.
