Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB26SKW01 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit Configuration: DPDT
• Switch Function: On-On
• Voltage Rating - AC: 125V
• Voltage Rating - DC: 30V
• Mounting Type: Panel Mount, Front
• Actuator Type: Plunger for Cap
• Operating Temperature Range: -25°C to 70°C
• RoHS Compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Current Rating: May be equal to or greater than 1A
• Mechanical Life: May be equal to or greater than 100,000 cycles
• Electrical Life: May be equal to or greater than 50,000 cycles
• Termination Style: Alternative termination methods acceptable if electrical connection is maintained
• Panel Cutout Dimensions: Larger cutout dimensions acceptable with mechanical adaptation

The YB26SKW01 qualifies as a substitute part based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The YB26SKW01 is the qualified substitute for the KB26SKW01 based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical voltage ratings (125V AC, 30V DC) and circuit configuration (DPDT On-On). The YB26SKW01 provides enhanced current capacity (3A versus 1A), which is acceptable for applications originally specified for 1A operation.

Mechanical Compatibility: Both parts feature identical mounting type (Panel Mount, Front) and actuator type (Plunger for Cap). The YB26SKW01 requires a larger panel cutout (16.00mm versus 12.30mm), necessitating mechanical panel adaptation.

Operational Durability: The YB26SKW01 exceeds the mechanical and electrical life specifications of the KB26SKW01 (200,000 versus 100,000 mechanical cycles; 100,000 versus 50,000 electrical cycles), providing extended service life.

Compliance Status: Both parts are ROHS3 Compliant and carry identical environmental certifications (REACH Unaffected, ECCN EAR99). The YB26SKW01 maintains Active product status, ensuring ongoing availability and supply chain continuity.

Termination Consideration: The YB26SKW01 offers dual termination options (Solder and Quick Connect 0.110" 2.8mm) compared to the KB26SKW01 solder lug termination. Circuit board modifications may be required to accommodate the alternative termination method.

Frequently Asked Questions (FAQ)

Q: Can the YB26SKW01 directly replace the KB26SKW01 without any modifications?

A: Electrical and functional replacement is direct. Mechanical adaptation is required due to the larger panel cutout dimension (16.00mm versus 12.30mm). Termination style differences may require circuit board layout adjustments.

Q: What is the primary reason for substitution?

A: The KB26SKW01 carries Obsolete product status. The YB26SKW01 is an Active product from the same manufacturer with identical electrical specifications and enhanced operational durability.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts maintain identical voltage ratings and circuit configuration. The YB26SKW01 provides higher current capacity (3A versus 1A), which does not negatively impact applications designed for lower current operation.

Q: What mechanical considerations apply to this substitution?

A: The panel cutout diameter increases from 12.30mm to 16.00mm. Existing panel mounting holes must be enlarged or the panel must be modified to accommodate the larger switch body.

Q: Does the termination style difference affect compatibility?

A: The YB26SKW01 offers Solder and Quick Connect termination options versus the KB26SKW01 solder lug only. If the solder termination is selected, circuit board modifications may still be necessary due to different terminal geometry. Quick Connect termination requires compatible receptacles.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the KB26SKW01 and YB26SKW01 are ROHS3 Compliant and REACH Unaffected, meeting current environmental standards.

Q: What is the inventory status of these parts?

A: The KB26SKW01 (Obsolete) has 810 units in stock. The YB26SKW01 (Active) has 714 units in stock, with ongoing availability through the manufacturer.
