SB265/C Equivalent & Substitute Parts

Part Overview

The SB265/C is a pushbutton switch manufactured by NKK Switches, classified as a standard panel mount SPST (Single Pole Single Throw) switch rated for 6A at 125V AC. This component features a plunger actuator with solder lug termination and is designed for on-off switching applications. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and component sourcing in legacy equipment applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SB265/C is determined by strict alignment with the following critical parameters:

• Circuit configuration: SPST topology
• Current rating: 6A AC minimum
• Voltage rating: 125V AC minimum
• Mounting interface: Panel mount, rear configuration
• Termination: Solder lug connection
• Actuator mechanism: Plunger type
• Panel cutout compatibility: Circular 12.50mm diameter
• Environmental compliance: ROHS3 and REACH status

The MB2065SB1W01/C qualifies as a substitute based on shared manufacturer lineage (NKK Switches), identical electrical ratings, compatible mounting and termination specifications, and equivalent environmental compliance certifications. The transition from the obsolete SB series to the active MB2065S base product represents a direct product line evolution within the manufacturer's portfolio.

Engineering Selection Recommendations

The MB2065SB1W01/C represents the active product line successor to the obsolete SB265/C within NKK Switches' pushbutton switch portfolio. Selection of the MB2065SB1W01/C is supported by:

• Identical manufacturer source, ensuring design continuity and quality standards
• Active product status, providing ongoing availability and supply chain reliability
• Shared export classification (EAR99) and tariff coding (8536.50.9035), indicating regulatory equivalence
• Equivalent moisture sensitivity rating (MSL 1), confirming environmental robustness
• Documented SPST circuit topology alignment with the original component specification

Component selection should be validated against specific application requirements including electrical load characteristics, mechanical cycle frequency, and environmental exposure conditions within the stated operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the MB2065SB1W01/C directly replace the SB265/C in existing equipment?

A: The MB2065SB1W01/C shares the same manufacturer, circuit configuration (SPST), and environmental compliance certifications as the SB265/C. Compatibility depends on verification of electrical ratings (current and voltage), mounting interface dimensions, and termination style alignment with your specific application requirements.

Q: What is the significance of the SB265/C being obsolete?

A: Obsolete status indicates the component is no longer manufactured or supported by NKK Switches. The MB2065SB1W01/C, derived from the active MB2065S base product, represents the manufacturer's current equivalent offering for this switch category.

Q: Are there differences in mechanical life or electrical life between these parts?

A: The provided data specifies 30,000 mechanical cycles and 10,000 electrical cycles for the SB265/C. Equivalent performance specifications for the MB2065SB1W01/C are not included in the available technical parameters and should be obtained from the manufacturer's current datasheet.

Q: How do I verify panel cutout compatibility?

A: The SB265/C requires a circular 12.50mm diameter panel cutout. Confirm that the MB2065SB1W01/C maintains this same mechanical interface specification before installation in existing panel assemblies.

Q: What does MSL 1 (Unlimited) mean for component handling?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity limitations and does not require special storage or handling conditions. Both the SB265/C and MB2065SB1W01/C share this classification.
