Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MB2065SD3W01-BC are qualified based on the following critical parameters that determine functional equivalence:

• Circuit configuration: SPDT topology required
• Switch function: On-On operation
• Current capacity: Minimum 6A AC rating
• Voltage ratings: Minimum 125V AC and 28V DC or higher
• Mounting configuration: Panel mount, rear installation
• Termination: Solder lug connections
• Panel cutout compatibility: Circular aperture within acceptable tolerance range (6.35mm to 6.50mm)
• Compliance: ROHS3 compliance and MSL Level 1

The three substitute parts listed meet these core electrical and mechanical requirements while maintaining compatibility with the original application envelope.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are ROHS3 compliant and carry MSL Level 1 rating, meeting regulatory requirements equivalent to the original MB2065SD3W01-BC component.

8161SHZQE2 (C&K): Active product status with 4,971 units in stock. Meets minimum electrical specifications with 6A AC and 6A DC current capacity. Operating temperature range is limited to -30°C to 65°C compared to the original 85°C maximum. Panel cutout diameter is 6.35mm, requiring verification for mechanical fit in existing panel apertures designed for 6.50mm. REACH status is affected.

MPA106D (TE Connectivity ALCOSWITCH): Active product status with 1,136 units in stock. Electrical specifications exceed minimum requirements with 6A AC and 4A DC capacity. Operating temperature range is -20°C to 80°C. Panel cutout diameter is 6.35mm. REACH status is affected.

MPE106D (TE Connectivity ALCOSWITCH): Active product status with 2,200 units in stock. Electrical specifications exceed minimum requirements with 6A AC and 4A DC capacity. Ingress protection rated as Splash Proof, providing environmental protection comparable to the original IP67 rating. Operating temperature range is -20°C to 80°C. Panel cutout diameter is 6.35mm. REACH status is affected.

Frequently Asked Questions (FAQ)

Q: Can the 8161SHZQE2 be used in applications requiring operation above 65°C?

A: No. The 8161SHZQE2 has a maximum operating temperature of 65°C, while the original MB2065SD3W01-BC operates to 85°C. Applications requiring the full temperature range must use MPA106D or MPE106D.

Q: What is the impact of the 6.35mm panel cutout diameter on mechanical compatibility?

A: The substitute parts feature a 6.35mm circular cutout diameter compared to the original 6.50mm. Panel apertures designed for 6.50mm will require modification or use of adapter hardware to accommodate the smaller diameter of substitute components.

Q: Are all substitute parts suitable for DC applications?

A: All substitute parts support DC operation. The 8161SHZQE2 provides 6A DC capacity, while MPA106D and MPE106D each provide 4A DC capacity. The original MB2065SD3W01-BC is rated for 3A DC, so all substitutes meet or exceed this requirement.

Q: What is the difference between the MPA106D and MPE106D?

A: Both parts share identical electrical specifications and operating temperature ranges. The primary difference is ingress protection: MPE106D is rated Splash Proof, while MPA106D has no specified ingress protection rating. For applications requiring environmental sealing, MPE106D is the preferred selection.

Q: Are REACH-affected substitute parts acceptable for new designs?

A: REACH status indicates regulatory notification requirements. The original MB2065SD3W01-BC is REACH Unaffected, while all three substitutes are REACH Affected. Compliance determination depends on application jurisdiction and end-use classification. Consult regulatory requirements for your specific application.
