Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB26SKW01-12-EB is based on the following critical parameters that must remain compatible:

Electrical Compatibility Requirements:

• Circuit configuration must be DPDT
• Switch function must be On-On
• Voltage ratings must support minimum 125V AC and 30V DC operation
• Illumination voltage must be compatible with 12V supply

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Front
• Operating temperature range must encompass -25°C ~ 50°C
• Panel cutout dimensions must accommodate the switch body

Regulatory Compliance:

• RoHS3 compliance required
• REACH unaffected status required

The YB26SKW01-5D12-JD meets these substitution criteria while offering enhanced performance characteristics in current rating, mechanical life, and electrical life.

Parameter Comparison

Engineering Selection Recommendations

The YB26SKW01-5D12-JD is a suitable substitute for the obsolete KB26SKW01-12-EB based on the following factors:

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications requiring these certifications.

Product Availability: The substitute part maintains active product status with 995 units in stock, providing supply chain reliability compared to the obsolete main part.

Electrical Equivalence: Both components support identical voltage ratings (125V AC / 30V DC) and DPDT On-On switching function, maintaining electrical compatibility in circuit designs.

Mechanical Compatibility: Panel mount configuration and operating temperature range remain consistent. Panel cutout diameter increases from 12.30mm to 16.00mm, requiring panel modification for physical installation.

Performance Enhancement: The substitute offers superior mechanical life (200,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles), providing extended component longevity.

Operational Differences: Illumination technology transitions from incandescent yellow (12 VAC) to LED amber (12 VDC), and termination style changes from solder lug to solder with quick connect options. Current rating increases from 1A to 3A, providing additional capacity margin.

Frequently Asked Questions (FAQ)

Q: Can the YB26SKW01-5D12-JD directly replace the KB26SKW01-12-EB without circuit modifications?

A: Electrical substitution is valid for DPDT On-On switching applications operating at 125V AC or 30V DC. However, illumination voltage changes from 12 VAC to 12 VDC, requiring power supply adjustment. Panel cutout diameter increases from 12.30mm to 16.00mm, necessitating mechanical panel modification.

Q: What are the key differences in illumination between these components?

A: The main part uses incandescent yellow illumination powered by 12 VAC. The substitute uses LED amber illumination powered by 12 VDC. LED technology provides longer operational life and reduced power consumption compared to incandescent sources.

Q: Are there current rating implications for substitution?

A: The substitute part supports 3A current rating compared to the main part's 1A rating. This higher rating is backward compatible with 1A applications and provides additional capacity margin for higher-current switching requirements.

Q: What packaging considerations apply to this substitution?

A: The main part uses standard packaging, while the substitute is supplied in tray packaging. Termination style changes from solder lug to solder with quick connect 0.110" (2.8mm) options, affecting circuit board integration methods.

Q: Do both components meet the same regulatory requirements?

A: Both components are ROHS3 compliant and REACH unaffected, maintaining regulatory equivalence for applications requiring these certifications.
