Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2185SD3W01 is determined by strict equivalence across the following critical parameters:

• Circuit configuration must be 4PDT
• AC voltage rating must be 125V minimum
• AC current rating must be 6A minimum
• DC voltage rating must be 30V minimum
• Mounting type must be Panel Mount, Rear
• Termination style must be Solder Lug
• Panel cutout diameter must be 6.50mm
• Operating temperature range must encompass -30°C to 85°C
• RoHS3 compliance required

Two substitute parts meet these criteria: MB2185SS1W01 (NKK Switches) and 8N4011-Z (Nidec Components Corporation). Both maintain identical electrical specifications for AC operation and mechanical compatibility with the original design.

Parameter Comparison

Engineering Selection Recommendations

MB2185SS1W01 is a direct equivalent from the same manufacturer series (MB2000). Both parts share identical electrical ratings and mechanical specifications. This part maintains the original IP67 ingress protection rating and is ROHS3 compliant. Selection of this substitute provides continuity with the original design without electrical or mechanical modification.

8N4011-Z is a functionally equivalent substitute from Nidec Components Corporation. It meets all critical electrical and mechanical parameters, with the exception that DC current rating is 4A versus 3A on the original part. This represents an improvement in DC current capacity. The 8N4011-Z is currently in active production status, ensuring long-term availability. ROHS3 compliance is maintained.

Both substitutes are suitable for direct replacement in applications where the MB2185SD3W01 was originally specified.

Frequently Asked Questions (FAQ)

Q: Can MB2185SS1W01 be used as a direct replacement for MB2185SD3W01?

A: Yes. Both parts are 4PDT switches with identical AC ratings (6A at 125V), DC ratings (3A at 30V), panel mount rear configuration, 6.50mm circular cutout, and solder lug termination. Both are ROHS3 compliant and operate across -30°C to 85°C.

Q: What is the difference between MB2185SS1W01 and 8N4011-Z?

A: Both are functionally equivalent for AC operation. The primary difference is DC current rating: MB2185SS1W01 is rated 3A DC, while 8N4011-Z is rated 4A DC. The 8N4011-Z is in active production; MB2185SS1W01 is obsolete. Ingress protection specifications are not provided for either substitute.

Q: Is the 8N4011-Z suitable for applications requiring IP67 protection?

A: Ingress protection rating is not specified for the 8N4011-Z. If IP67 protection is a design requirement, this parameter must be confirmed with the manufacturer before selection.

Q: Are all three parts ROHS3 compliant?

A: Yes. MB2185SD3W01, MB2185SS1W01, and 8N4011-Z are all ROHS3 compliant.

Q: Can these switches be used interchangeably in existing PCB designs?

A: Yes, provided the PCB layout accommodates the 6.50mm circular panel cutout and solder lug termination. All three parts share identical mechanical mounting specifications.
