MB2011LS1W08 Equivalent & Substitute Parts

Part Overview

The MB2011LS1W08 is a pushbutton switch with SPDT (Single Pole Double Throw) circuit configuration manufactured by NKK Switches from the MB2000 series. This component is rated for 6A at 125V AC and 3A at 30V DC, featuring a plunger actuator with wire wrap termination and epoxy sealed terminals. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing maintenance, repair, and redesign applications where this switch is specified in legacy systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011LS1W08 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration (SPDT)
• Switch function (On-Mom momentary operation)
• Current rating minimum: 6A AC / 3A DC
• Voltage rating minimum: 125V AC / 30V DC
• Mounting type: Panel Mount, Rear
• Termination style: Wire Wrap
• Panel cutout diameter: 6.50mm (or compatible with mechanical adaptation)

Identified Substitutes:

1. MB2011LS1A05 (NKK Switches) – Direct equivalent within the same MB2000 series with identical electrical and mechanical specifications. Differs only in packaging (Bulk vs. standard).

2. 8168S2HWQE2 (C&K) – Cross-manufacturer substitute from the 8060 series. Meets core electrical requirements with SPDT circuit and 6A AC/DC rating. Voltage ratings are 120V AC / 28V DC, which are within acceptable tolerance for most AC applications but represent a marginal reduction in DC voltage headroom. Panel cutout diameter is 6.35mm, requiring mechanical verification for panel compatibility.

Parameter Comparison

Engineering Selection Recommendations

MB2011LS1A05 (NKK Switches): This substitute is the preferred choice for direct replacement. It maintains identical electrical specifications (6A AC / 3A DC, 125V AC / 30V DC), mechanical configuration, and operating temperature range. Both parts are obsolete with equivalent RoHS3 compliance. The only distinction is packaging format (Bulk). This part is suitable for applications requiring no design modification.

8168S2HWQE2 (C&K): This substitute is suitable for applications where the following conditions are met: (1) AC voltage operation at 120V or lower, (2) DC voltage operation at 28V or lower, (3) operating temperature range limited to -30°C to 65°C, and (4) mechanical panel cutout diameter of 6.35mm is compatible with existing panel geometry. The C&K part offers the advantage of active product status and extended electrical life (50,000 cycles vs. 25,000 cycles). REACH compliance status differs (Affected vs. Unaffected), requiring verification against applicable regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can MB2011LS1A05 be used as a direct replacement for MB2011LS1W08?

A: Yes. Both parts are from the NKK Switches MB2000 series with identical electrical ratings (6A AC / 3A DC, 125V AC / 30V DC), circuit configuration (SPDT), switch function (On-Mom), mounting type (Panel Mount, Rear), termination style (Wire Wrap), and panel cutout diameter (6.50mm). The parts differ only in packaging. No circuit or mechanical modifications are required.

Q: What are the limitations of using 8168S2HWQE2 as a substitute?

A: The 8168S2HWQE2 has three operational constraints: (1) AC voltage rating is 120V instead of 125V, (2) DC voltage rating is 28V instead of 30V, and (3) maximum operating temperature is 65°C instead of 85°C. Additionally, the panel cutout diameter is 6.35mm versus 6.50mm, which may require panel modification or mechanical adaptation. These differences must be evaluated against the specific application requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both MB2011LS1A05 and 8168S2HWQE2 are ROHS3 compliant, matching the original MB2011LS1W08 specification.

Q: What is the difference in electrical life between the main part and the C&K substitute?

A: The MB2011LS1W08 has an electrical life rating of 25,000 cycles, while the 8168S2HWQE2 is rated for 50,000 cycles. This represents a 2x improvement in electrical life for the C&K part.

Q: Does the packaging format affect electrical or mechanical performance?

A: No. Packaging format (standard vs. Bulk for MB2011LS1A05) does not affect electrical performance, mechanical specifications, or functional characteristics. It relates only to order quantity and handling logistics.

Q: What should be verified before selecting 8168S2HWQE2 for a legacy system?

A: Verify that the application operates within the C&K part's voltage limits (120V AC maximum, 28V DC maximum), temperature range (-30°C to 65°C), and that the 6.35mm panel cutout diameter is mechanically compatible with existing panel geometry. Additionally, confirm that REACH compliance status (Affected) meets regulatory requirements for the end application.
