Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB2011SS1W03/CUL is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Circuit configuration (SPDT)
• Current rating minimum: 6A AC / 3A DC
• Voltage rating minimum: 125V AC / 30V DC
• Switch function (On-Mom)

Mechanical Compatibility Criteria:

• Mounting type (Panel Mount, Rear)
• Actuator type (Plunger for Cap)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular - 6.50mm Dia)
• Operating temperature range (-30°C to 85°C)

Compliance & Lifecycle Criteria:

• RoHS3 compliance
• Moisture Sensitivity Level 1 or equivalent

The identified substitute part MB2011SS1W03/CUL-N987 maintains compatibility across these parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The MB2011SS1W03/CUL-N987 is the designated substitute for the obsolete MB2011SS1W03/CUL. Both components are manufactured by NKK Switches and maintain identical electrical ratings (6A AC at 125V, 3A DC at 30V) and mechanical specifications (SPDT circuit, panel mount rear configuration, plunger actuator, PC pin termination).

The primary advantage of the MB2011SS1W03/CUL-N987 is its active product status, ensuring continued availability and supply chain reliability. Both parts maintain ROHS3 compliance and equivalent moisture sensitivity ratings, supporting long-term deployment in regulated environments.

Selection of the substitute part is appropriate for new designs, system upgrades, and replacement applications where the original component is no longer available.

Frequently Asked Questions (FAQ)

Q: Can MB2011SS1W03/CUL-N987 be used as a direct replacement for MB2011SS1W03/CUL?

A: Yes. Both components share identical electrical ratings (6A AC at 125V, 3A DC at 30V), circuit configuration (SPDT), and mechanical specifications (panel mount rear, plunger actuator, PC pin termination, 6.50mm circular cutout). The substitute maintains compatibility across all critical parameters.

Q: What is the difference between these two part numbers?

A: The primary difference is product status. MB2011SS1W03/CUL is obsolete, while MB2011SS1W03/CUL-N987 is active. The suffix "-N987" indicates a packaging or configuration variant. Electrical and mechanical performance remain equivalent.

Q: Are there packaging differences between the main part and substitute?

A: The main part (MB2011SS1W03/CUL) is supplied in standard packaging, while the substitute (MB2011SS1W03/CUL-N987) is supplied in bulk packaging. This does not affect component functionality or electrical characteristics.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MB2011SS1W03/CUL and MB2011SS1W03/CUL-N987 are ROHS3 compliant with Moisture Sensitivity Level 1 (unlimited shelf life). Both are REACH unaffected and classified under ECCN EAR99.

Q: What operating temperature range should be expected?

A: Both components operate across -30°C to 85°C. Mechanical life is rated at 100,000 cycles, with electrical life at 25,000 cycles under specified load conditions.
