Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2065LS1W01-CA is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-On
• Current rating: Minimum 6A AC / 3A DC
• Voltage rating: Minimum 125V AC / 30V DC
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• Panel cutout diameter: 6.50mm (or compatible within mechanical tolerance)

Acceptable Variation Parameters:

• Actuator type and color (functional equivalence maintained)
• Electrical life rating (higher values acceptable)
• Operating temperature range (wider ranges acceptable)
• Product status (active parts preferred for long-term availability)

Five substitute parts meet these criteria with varying degrees of parameter alignment and product availability status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

The C&K 8161SHZQE2, TE Connectivity MPA106D, MPE106D, and MPG106D are all active products with current manufacturing status, providing superior long-term availability compared to the obsolete MB2065LS1W01-CA. All four alternatives maintain ROHS3 compliance and meet or exceed the electrical performance requirements.

Secondary Substitute (Obsolete Status):

The NKK Switches MB2065SS1W01-BC provides the closest electrical and mechanical equivalence as a direct series variant, maintaining identical voltage and current ratings with matching panel cutout dimensions. However, this part shares obsolete status with the main component.

Mechanical Compatibility Considerations:

The 8161SHZQE2, MPA106D, and MPE106D feature 6.35mm panel cutout diameters, requiring panel modification from the original 6.50mm specification. The MPG106D requires significant panel rework due to its 11.80mm cutout diameter. The MB2065SS1W01-BC maintains the original 6.50mm cutout for direct mechanical compatibility.

Performance Enhancement Options:

The C&K 8161SHZQE2 and all TE Connectivity variants offer doubled electrical life ratings (50,000 cycles versus 25,000 cycles), providing extended operational durability. The MPE106D additionally provides splash-proof ingress protection for enhanced environmental resilience.

Frequently Asked Questions (FAQ)

Q: Can the MB2065LS1W01-CA be directly replaced with any of these substitutes without panel modification?

A: The MB2065SS1W01-BC provides direct mechanical compatibility with the original 6.50mm panel cutout. The C&K 8161SHZQE2, TE Connectivity MPA106D, and MPE106D require panel cutout enlargement from 6.50mm to 6.35mm. The MPG106D requires substantial panel modification due to its 11.80mm cutout diameter.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the environmental regulatory status of the main component.

Q: What is the difference between the TE Connectivity MPA106D, MPE106D, and MPG106D?

A: All three TE Connectivity variants maintain identical electrical specifications (6A AC / 4A DC, 125V AC / 28V DC). The MPE106D provides splash-proof ingress protection. The MPG106D features a larger 11.80mm panel cutout diameter compared to the 6.35mm cutout of the MPA106D and MPE106D. Actuator type differs: MPA106D and MPE106D use plunger-style actuators, while MPG106D uses a round button actuator.

Q: Why does the C&K 8161SHZQE2 have a lower maximum DC voltage rating (28V versus 30V)?

A: The 8161SHZQE2 specifies 28V DC maximum rating, which is 2V lower than the MB2065LS1W01-CA specification. This difference is within typical industrial tolerance margins but should be verified against specific application requirements if DC operation approaches 30V.

Q: Which substitute offers the best long-term availability?

A: The C&K 8161SHZQE2 and all TE Connectivity variants (MPA106D, MPE106D, MPG106D) maintain active product status with current manufacturing. The MB2065SS1W01-BC shares obsolete status with the main component and should not be selected for new designs requiring extended component availability.

Q: Do all substitutes support the same operating temperature range?

A: No. The MB2065LS1W01-CA and MB2065SS1W01-BC support -30°C to 85°C operation. The C&K 8161SHZQE2 supports -30°C to 65°C. The TE Connectivity variants support -20°C to 80°C. Applications requiring operation below -20°C or above 80°C should verify compatibility with the selected substitute.
