MB2065LS1W01-BA Equivalent & Substitute Parts

Part Overview

The MB2065LS1W01-BA 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 component is classified as obsolete, making identification of functionally equivalent alternatives essential for design continuity and procurement planning. Substitute parts must maintain electrical performance specifications and mechanical compatibility with the original panel mount configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Circuit Configuration: All substitutes must maintain SPDT topology
• Switch Function: On-On operation required
• Current Rating: Minimum 6A AC capacity; DC rating of 3A or higher acceptable
• Voltage Rating: Minimum 125V AC and 28V DC or higher
• Mounting Configuration: Panel mount, rear termination with solder lug connections
• Panel Cutout Compatibility: Circular aperture diameter within acceptable mechanical tolerance
• Regulatory Compliance: ROHS3 compliance required

The four substitute parts listed (8161SHZQE1, MPA106D, MPE106D, MPG106D) meet these core electrical and mechanical criteria, though variations exist in secondary parameters such as actuator design, ingress protection rating, and panel cutout dimensions.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts maintain active product status, ensuring ongoing availability and manufacturer support. Each substitute meets the core electrical requirements of 6A AC switching capacity at 125V AC minimum and maintains ROHS3 compliance.

8161SHZQE1 (C&K): Offers equivalent AC current and voltage ratings with superior DC current capacity (6A). Operating temperature range extends to -30°C, matching the original part's lower limit. Panel cutout diameter of 6.35mm requires mechanical verification for existing panel apertures designed for 6.50mm. Electrical life specification of 50,000 cycles exceeds the original 25,000-cycle rating.

MPA106D (TE Connectivity ALCOSWITCH): Maintains exact AC voltage and current specifications with 4A DC capacity. Panel cutout diameter of 6.35mm requires mechanical assessment. Operating temperature range of -20°C to 80°C is narrower than the original specification. Electrical life of 50,000 cycles provides extended service life.

MPE106D (TE Connectivity ALCOSWITCH): Identical electrical specifications to MPA106D with addition of splash-proof ingress protection, providing enhanced environmental resilience. Panel cutout diameter of 6.35mm requires mechanical verification. Electrical life of 50,000 cycles exceeds original specification.

MPG106D (TE Connectivity ALCOSWITCH): Meets all electrical requirements with round button actuator matching the original design. Panel cutout diameter of 11.80mm represents a significant mechanical deviation, requiring panel redesign or adapter consideration. Electrical life of 50,000 cycles provides extended operational cycles.

Frequently Asked Questions (FAQ)

Q: Can any of these substitutes be used as direct drop-in replacements?

A: Direct mechanical compatibility depends on panel cutout diameter. The 8161SHZQE1, MPA106D, and MPE106D feature 6.35mm cutout diameters, which are 0.15mm smaller than the original 6.50mm specification. The MPG106D requires significant panel modification due to its 11.80mm cutout diameter. Electrical compatibility is maintained across all four substitutes for the specified voltage and current parameters.

Q: What are the key electrical differences between substitutes?

A: All substitutes maintain 6A AC current capacity and 125V AC voltage rating. DC current ratings vary: 8161SHZQE1 provides 6A DC, while MPA106D, MPE106D, and MPG106D each provide 4A DC, compared to the original 3A DC specification. All substitutes exceed the original 25,000-cycle electrical life with 50,000-cycle ratings.

Q: Which substitute offers the best environmental performance?

A: MPE106D is the only substitute with splash-proof ingress protection, providing enhanced environmental resilience compared to the original part and other substitutes. This specification is relevant only if environmental protection is required in the application.

Q: Are there temperature range considerations for substitute selection?

A: The original MB2065LS1W01-BA operates from -30°C to 85°C. The 8161SHZQE1 maintains the -30°C lower limit but reduces the upper limit to 65°C. The TE Connectivity substitutes (MPA106D, MPE106D, MPG106D) operate from -20°C to 80°C, narrowing both temperature extremes. Application temperature requirements should guide selection.

Q: What packaging formats are available?

A: The original part is supplied in bulk packaging. The 8161SHZQE1 is supplied in tray packaging. All TE Connectivity substitutes (MPA106D, MPE106D, MPG106D) are supplied in bulk packaging, matching the original format.
