Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2061SS2W45/U is determined by strict alignment of the following critical parameters:

• Circuit Configuration: DPDT topology must be maintained
• Switch Function: On-momentary operation requirement
• Mounting Type: Through-hole, right-angle, vertical orientation
• Current and Voltage Ratings: AC 6A @ 125V and DC 3A @ 30V minimum
• Termination Style: PC pin configuration
• Panel Cutout Dimensions: Circular 6.50mm diameter
• Operating Temperature Range: -30°C to +85°C capability
• Mechanical and Electrical Life: 100,000 cycles mechanical and 25,000 cycles electrical minimum
• Compliance: RoHS3 compliance required

The identified substitute part MB2061SS2W45/CUL-235F is classified within the same MB2000 series from NKK Switches and maintains compatibility across all specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The MB2061SS2W45/CUL-235F serves as a direct functional equivalent to the obsolete MB2061SS2W45/U. Both components maintain identical electrical specifications, mechanical life ratings, and environmental operating parameters. The primary distinction is product status: the substitute part is currently active in production, ensuring long-term availability and supply chain continuity.

Both parts maintain RoHS3 compliance and MSL 1 moisture sensitivity rating, supporting deployment in standard industrial and commercial applications without additional environmental controls. The active status of the substitute part makes it the preferred selection for new designs and ongoing production requirements where the obsolete main part is no longer available through standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Can MB2061SS2W45/CUL-235F be used as a direct replacement for MB2061SS2W45/U in existing designs?

A: Yes. Both parts share identical DPDT circuit configuration, on-momentary switch function, through-hole right-angle vertical mounting, 6A AC @ 125V and 3A DC @ 30V current ratings, PC pin termination, and 6.50mm circular panel cutout dimensions. Electrical and mechanical performance characteristics are equivalent.

Q: What is the primary reason for substitution?

A: The MB2061SS2W45/U is obsolete. The MB2061SS2W45/CUL-235F is an active production part from the same manufacturer and series, providing equivalent functionality with assured supply availability.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are RoHS3 compliant with MSL 1 moisture sensitivity rating. Compliance certifications are equivalent.

Q: What are the critical parameters that must match for substitution eligibility?

A: Circuit configuration (DPDT), switch function (on-momentary), mounting type (through-hole right-angle vertical), current ratings (6A AC @ 125V, 3A DC @ 30V), termination style (PC pin), panel cutout (6.50mm circular), operating temperature range (-30°C to +85°C), and mechanical/electrical life ratings (100,000 and 25,000 cycles respectively).

Q: Is the panel cutout dimension identical between both parts?

A: Yes. Both parts require a circular 6.50mm diameter panel cutout, ensuring mechanical compatibility in existing panel layouts.

Q: What is the operating temperature capability of both parts?

A: Both parts operate across the range of -30°C to +85°C, supporting standard industrial temperature environments.
