KB16SKW01 Equivalent & Substitute Parts

Part Overview

The KB16SKW01 is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with On-On switching function. This component is rated for 1A at 125V AC and 30V DC, with a panel mount front configuration and solder lug termination. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this series is no longer available.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB16SKW01 is determined by the following critical parameters:

• Circuit Configuration: Must be SPDT to maintain electrical functionality
• Switch Function: Must be On-On to preserve operational behavior
• Voltage Rating: Must support minimum 125V AC and 30V DC
• Mounting Type: Must be Panel Mount, Front to ensure mechanical compatibility
• Operating Temperature Range: Must encompass -25°C to 70°C minimum
• Compliance: Must maintain ROHS3 compliance and REACH unaffected status

The YB16SKW01 qualifies as a substitute based on these parameters. While it exhibits higher current rating (3A versus 1A), enhanced mechanical life (200,000 versus 100,000 cycles), and improved electrical life (100,000 versus 50,000 cycles), these represent performance enhancements rather than incompatibilities. The substitute maintains identical circuit configuration, switch function, voltage ratings, mounting type, and temperature range. The YB16SKW01 is classified as active product status, ensuring continued availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

The YB16SKW01 serves as the primary substitute for KB16SKW01 applications. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment across replacement scenarios. The transition from obsolete to active product status provides supply chain continuity and eliminates long-lead-time procurement risks associated with discontinued components.

The YB16SKW01 demonstrates enhanced performance characteristics including doubled mechanical life (200,000 cycles) and doubled electrical life (100,000 cycles), providing extended operational reliability. The increased current rating (3A versus 1A) presents no compatibility constraint in applications designed for the original 1A specification, as the substitute accommodates the original load requirements with additional capacity margin.

Panel cutout dimension differences (16.00mm for YB16SKW01 versus 12.30mm for KB16SKW01) require mechanical panel modification. Termination style variation (Solder, Quick Connect 0.110" for YB16SKW01 versus Solder Lug for KB16SKW01) necessitates circuit board connection method adjustment. These mechanical and electrical interface changes must be evaluated within specific application contexts.

Frequently Asked Questions (FAQ)

Q: Can YB16SKW01 directly replace KB16SKW01 without circuit modification?

A: Electrical functionality is compatible. Circuit board termination connections require modification due to different termination styles. Panel mounting requires enlargement of the cutout diameter from 12.30mm to 16.00mm.

Q: What is the significance of the higher current rating on YB16SKW01?

A: The 3A rating on YB16SKW01 versus 1A on KB16SKW01 indicates enhanced current-carrying capacity. Applications designed for 1A operation remain fully compatible, as the substitute accommodates the original specification with additional margin.

Q: Are both components compliant with current environmental regulations?

A: Both KB16SKW01 and YB16SKW01 maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What packaging differences exist between these components?

A: KB16SKW01 is supplied without specified packaging designation. YB16SKW01 is supplied in Tray packaging, which may affect inventory management and handling procedures.

Q: How do mechanical life ratings affect component selection?

A: KB16SKW01 specifies 100,000 mechanical cycles; YB16SKW01 specifies 200,000 cycles. For applications requiring extended operational life or frequent switching cycles, the YB16SKW01 provides enhanced durability. Standard applications within the original 100,000-cycle specification remain compatible with either component.

Q: What is the impact of product status on procurement?

A: KB16SKW01 is classified as obsolete, indicating discontinued manufacturing and potential supply unavailability. YB16SKW01 is classified as active, ensuring ongoing production, established supply chains, and predictable lead times for procurement planning.
