MB2065LS1W01/CUL Equivalent & Substitute Parts

Part Overview

The MB2065LS1W01/CUL is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 6A AC and 3A DC current ratings at 125V AC and 30V DC respectively. This component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. The switch employs a plunger actuator with solder lug termination and epoxy sealed terminals, designed for panel mount rear installation with a 6.50mm circular cutout.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MB2065LS1W01/CUL are identified based on the following critical parameters that determine functional equivalence:

• Circuit Configuration: SPDT topology required
• Switch Function: On-On operation
• Current Rating (AC): Minimum 6A at 125V AC
• Termination Style: Solder lug connection
• Mounting Type: Panel mount, rear installation
• Panel Cutout Compatibility: Circular configuration within acceptable tolerance range
• Regulatory Compliance: ROHS3 compliance maintained

The substitute parts MPA106D and MPE106D from TE Connectivity ALCOSWITCH Switches meet these core electrical and mechanical requirements. Both alternatives are active products with current manufacturing status, providing long-term availability and supply chain stability compared to the obsolete MB2065LS1W01/CUL.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106D and MPE106D are suitable substitutes for the obsolete MB2065LS1W01/CUL based on electrical and mechanical compatibility. Selection between the two active alternatives should consider the following factors:

MPA106D provides direct functional equivalence with matching AC/DC current and voltage ratings. This part maintains compatibility with existing panel cutout specifications within standard manufacturing tolerances.

MPE106D offers identical electrical performance with the additional benefit of splash proof ingress protection and extended electrical life rating (50,000 cycles versus 25,000 cycles for the original part). The splash proof feature provides enhanced environmental protection for applications requiring moisture resistance.

Both substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1) ratings, ensuring regulatory alignment with the original component. The active product status of both alternatives ensures continued availability and supply chain support for production and field replacement applications.

Frequently Asked Questions (FAQ)

Q: Can MPA106D and MPE106D be used interchangeably with MB2065LS1W01/CUL?

A: Both parts meet the core electrical requirements (SPDT circuit, 6A AC at 125V, solder lug termination, panel mount rear configuration). The 0.15mm difference in panel cutout diameter (6.50mm versus 6.35mm) falls within standard mechanical tolerances for circular panel mount applications. MPE106D provides additional splash proof protection.

Q: What is the impact of the reduced DC voltage rating on substitute parts?

A: The substitute parts are rated for 28V DC compared to the original 30V DC rating. For applications operating at or below 28V DC, this presents no functional limitation. Applications requiring operation above 28V DC would require alternative component selection.

Q: How do the electrical life ratings differ between the main part and substitutes?

A: The MB2065LS1W01/CUL is rated for 25,000 electrical cycles, while both MPA106D and MPE106D are rated for 50,000 electrical cycles. The substitute parts provide extended operational life, representing an improvement over the original specification.

Q: Are there packaging differences between these parts?

A: The MB2065LS1W01/CUL is packaged individually with specific packaging designation, while both MPA106D and MPE106D are supplied in bulk packaging. Bulk packaging may require adjustment to procurement and inventory management procedures.

Q: What is the significance of the splash proof rating on MPE106D?

A: The splash proof ingress protection on MPE106D provides enhanced environmental sealing compared to the original part and the MPA106D alternative. This feature is beneficial for applications exposed to moisture, condensation, or liquid splash conditions.
