Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the KB25SKW01-JB are identified based on the following criteria:

• Manufacturer alignment: Parts from NKK Switches maintain design consistency and quality standards
• Product category: Pushbutton switch functionality
• Moisture sensitivity level: MSL 1 (Unlimited) compatibility
• Active product status: Substitute parts must be in active production to ensure long-term availability

The YB25SKW01-JB meets these substitution criteria as an active NKK Switches pushbutton switch with identical moisture sensitivity classification.

Parameter Comparison

Engineering Selection Recommendations

The YB25SKW01-JB is an active substitute for the obsolete KB25SKW01-JB. Both components share the same manufacturer (NKK Switches) and identical moisture sensitivity classification (MSL 1 - Unlimited), ensuring compatibility in applications where environmental moisture exposure is not a limiting factor.

The YB25SKW01-JB provides additional technical specifications including DPDT circuit configuration, 3A current rating at AC/DC, 125V AC / 30V DC voltage ratings, and mechanical life of 1,000,000 cycles. The component maintains EAR99 export classification, consistent with standard commercial electronic components.

Selection of the YB25SKW01-JB as a substitute is supported by the active product status, ensuring availability for procurement and future supply chain continuity.
