KB16SKW01-5F-JB Equivalent & Substitute Parts

Part Overview

The KB16SKW01-5F-JB is a pushbutton switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 1A at 125V AC and 30V DC. This illuminated panel mount switch features a square button actuator with green LED illumination and solder lug termination. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and component procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the KB16SKW01-5F-JB is determined by the following critical parameters:

Circuit configuration (SPDT maintained)
Switch function (On-On operation)
Mounting type (Panel Mount, Front)
Actuator type (Square, Button)
Illumination type and color (LED, Green)
Operating temperature range (-25°C to 50°C)
RoHS compliance status (ROHS3)
Termination compatibility with existing circuit board design

The YB16SKW01-5F-JB qualifies as a substitute based on matching circuit topology, mounting configuration, actuator design, illumination characteristics, and environmental specifications. Differences in current rating, electrical/mechanical life, and termination style represent enhanced or alternative capabilities rather than incompatibilities.

Engineering Selection Recommendations

The YB16SKW01-5F-JB is an active product offering from NKK Switches and represents a direct functional substitute for the obsolete KB16SKW01-5F-JB. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

Selection of the YB16SKW01-5F-JB provides enhanced electrical and mechanical durability characteristics (3A current rating versus 1A, 200,000 mechanical cycles versus 100,000, and 100,000 electrical cycles versus 50,000). The illumination voltage differential (2.2 VDC versus 2.1 VDC) falls within acceptable tolerance for LED circuit operation.

Termination style differs between the two components. The KB16SKW01-5F-JB uses solder lug termination, while the YB16SKW01-5F-JB offers both solder and quick connect 0.110" (2.8mm) termination options. Circuit board design must accommodate the selected termination method. Panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical panel modification if physical space constraints exist.

Frequently Asked Questions (FAQ)

Q: Can the YB16SKW01-5F-JB directly replace the KB16SKW01-5F-JB without circuit modification?

A: Functional replacement is possible. Both components share identical circuit topology (SPDT), voltage ratings (125V AC / 30V DC), and illumination characteristics (LED, Green). Termination style compatibility must be verified against existing circuit board design. Panel cutout diameter modification may be required (12.30mm to 16.00mm).

Q: What is the significance of the current rating difference (1A versus 3A)?

A: The YB16SKW01-5F-JB supports higher current loads (3A) compared to the KB16SKW01-5F-JB (1A). This represents enhanced capability and does not create incompatibility. Applications requiring only 1A operation remain fully compatible with the higher-rated substitute.

Q: Are there termination compatibility concerns?

A: The KB16SKW01-5F-JB uses solder lug termination exclusively. The YB16SKW01-5F-JB provides solder and quick connect 0.110" (2.8mm) termination options. Circuit board design must support the selected termination method. Solder termination compatibility exists between both components.

Q: How do the mechanical and electrical life ratings affect component selection?

A: The YB16SKW01-5F-JB offers doubled mechanical life (200,000 cycles versus 100,000) and doubled electrical life (100,000 cycles versus 50,000). These enhanced ratings provide extended operational durability and do not create incompatibility with applications designed for the lower-rated KB16SKW01-5F-JB.

Q: What packaging considerations apply to these components?

A: The KB16SKW01-5F-JB is supplied in standard packaging. The YB16SKW01-5F-JB is supplied in bulk packaging. Procurement quantity and handling procedures may differ accordingly.

Q: Are both components compliant with current regulatory standards?

A: Both the KB16SKW01-5F-JB and YB16SKW01-5F-JB maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements for electronic component procurement and use.
