MB2061LS1W01 Equivalent & Substitute Parts

Part Overview

The MB2061LS1W01 is a DPDT pushbutton switch manufactured by NKK Switches, rated for 6A at 125V AC and 3A at 30V DC. This component features a plunger actuator with solder lug termination and is designed for panel mount, rear installation. The product is currently obsolete, making equivalent substitute parts necessary for ongoing maintenance, repair, and new design implementations where this switch specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2061LS1W01 is determined by the following critical parameters:

• Circuit Configuration: Must be DPDT to maintain electrical functionality
• Switch Function: Must be On-Momentary to preserve operational behavior
• Current Rating (AC): Must support minimum 6A at 125V AC
• Voltage Rating (AC): Must support minimum 125V AC
• Mounting Type: Must be Panel Mount, Rear to ensure mechanical compatibility
• Termination Style: Must be Solder Lug for circuit board integration
• Panel Cutout Diameter: Must accommodate circular 6.50mm or smaller diameter for panel installation

The substitute parts MPA206R and MPE206R meet these core electrical and mechanical requirements. Both are DPDT On-Momentary switches with 6A AC rating at 125V, panel mount rear configuration, and solder lug termination. Minor variations in DC current rating (4A versus 3A), DC voltage rating (28V versus 30V), and panel cutout diameter (6.35mm versus 6.50mm) remain within acceptable substitution parameters for this component category.

Parameter Comparison

Engineering Selection Recommendations

Both MPA206R and MPE206R are suitable substitutes for the obsolete MB2061LS1W01 based on electrical and mechanical compatibility. Selection between the two TE Connectivity alternatives depends on environmental requirements:

MPA206R is appropriate for standard indoor applications where ingress protection is not a design requirement. This part maintains active product status with full manufacturer support and ROHS3 compliance.

MPE206R is appropriate for applications requiring splash proof protection. This variant provides the same electrical specifications as MPA206R with the addition of splash proof ingress protection, making it suitable for environments with moisture exposure or washdown conditions.

Both substitute parts exceed the original electrical life specification (50,000 cycles versus 25,000 cycles), providing improved durability. The slightly reduced operating temperature range (-20°C to 80°C versus -30°C to 85°C) and panel cutout diameter (6.35mm versus 6.50mm) are acceptable for most applications. DC current and voltage ratings are higher on the substitutes, ensuring compatibility with existing DC circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can MPA206R or MPE206R directly replace MB2061LS1W01 in existing designs?

A: Yes, both parts are electrically and mechanically compatible. The DPDT circuit configuration, On-Momentary function, 6A AC rating at 125V, panel mount rear configuration, and solder lug termination are identical. Panel cutout diameter is slightly smaller (6.35mm versus 6.50mm), which is acceptable for panel installations designed for the original part.

Q: What is the difference between MPA206R and MPE206R?

A: Both parts share identical electrical specifications. MPE206R includes splash proof ingress protection, while MPA206R does not specify ingress protection. Select MPE206R for applications exposed to moisture or washdown environments.

Q: Are there any temperature range limitations when substituting?

A: The substitute parts operate from -20°C to 80°C, compared to the original -30°C to 85°C range. For applications requiring operation below -20°C or above 80°C, the original specification must be verified against actual system requirements.

Q: How do the electrical life ratings compare?

A: MPA206R and MPE206R are rated for 50,000 electrical cycles, double the original MB2061LS1W01 specification of 25,000 cycles. This represents improved component durability.

Q: Are both substitute parts RoHS compliant?

A: Yes, both MPA206R and MPE206R are ROHS3 compliant, matching the compliance status of the original MB2061LS1W01.

Q: What packaging is available for the substitute parts?

A: Both MPA206R and MPE206R are supplied in bulk packaging.
