KB16SKW01-A Equivalent & Substitute Parts

Part Overview

The KB16SKW01-A is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with On-On switch function. This component is rated for 1A at 125V AC and 30V DC, with a panel mount front installation design and solder lug termination. The product is classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB16SKW01-A is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-On
• Voltage rating: 125V AC minimum
• Mounting type: Panel Mount, Front
• Operating temperature range: -25°C to 70°C minimum

Allowable Variation Parameters:

• Current rating: May exceed 1A (higher current rating is backward compatible)
• Mechanical and electrical life: May exceed specified cycles
• Panel cutout diameter: Larger diameter acceptable with mechanical redesign consideration
• Termination style: Alternative termination acceptable if electrical connection is maintained
• Actuator color: Functional variation only

The substitute part YB16WSKW01-CB meets all mandatory matching criteria while providing enhanced specifications in current rating (3A), mechanical life (200,000 cycles), and electrical life (100,000 cycles).

Parameter Comparison

Engineering Selection Recommendations

The YB16WSKW01-CB is a qualified substitute for the KB16SKW01-A based on the following engineering criteria:

Functional Compatibility: Both components share identical circuit configuration (SPDT), switch function (On-On), voltage ratings (125V AC / 30V DC), and operating temperature range (-25°C to 70°C). The substitute's 3A current rating exceeds the original 1A specification, providing enhanced capacity for the same electrical load.

Compliance Status: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications requiring these certifications. The substitute's active product status ensures long-term availability and supply chain continuity compared to the obsolete original part.

Mechanical Considerations: The substitute features a larger panel cutout diameter (16.00mm versus 12.30mm), requiring panel modification for direct replacement. The termination style differs (Quick Connect option available in addition to solder), offering installation flexibility.

Performance Enhancement: The substitute provides doubled mechanical life (200,000 versus 100,000 cycles) and doubled electrical life (100,000 versus 50,000 cycles), supporting extended operational reliability. IP65 ingress protection rating provides additional environmental resistance not specified in the original part.

Frequently Asked Questions (FAQ)

Q: Can YB16WSKW01-CB directly replace KB16SKW01-A without modification?

A: Electrical and functional replacement is direct. Mechanical panel modification is required due to the larger 16.00mm cutout diameter compared to the original 12.30mm specification.

Q: What is the significance of the higher 3A current rating on the substitute?

A: The 3A rating on YB16WSKW01-CB exceeds the original 1A specification. This provides additional capacity margin for the same electrical load and is fully backward compatible for applications requiring 1A or less.

Q: Are there termination compatibility considerations?

A: The substitute offers both solder and Quick Connect - 0.110" (2.8mm) termination options, compared to the original solder lug only. Solder termination is available, maintaining compatibility with existing solder lug connections.

Q: How do the lifecycle specifications compare?

A: YB16WSKW01-CB provides enhanced durability with 200,000 mechanical cycles and 100,000 electrical cycles, compared to 100,000 mechanical and 50,000 electrical cycles for KB16SKW01-A. This represents a 2x improvement in both metrics.

Q: What is the impact of IP65 ingress protection on the substitute?

A: The IP65 rating (dust tight, water resistant) on YB16WSKW01-CB provides environmental protection not specified in the original part. This is an enhancement suitable for applications requiring moisture or dust resistance.

Q: Are both parts RoHS compliant?

A: Yes. Both KB16SKW01-A and YB16WSKW01-CB maintain ROHS3 compliance, ensuring regulatory alignment for applications requiring RoHS certification.
