Matching Parameters (Substitution Basis):

• Circuit configuration: DPDT
• Switch function: On-On
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 28V AC/DC
• Actuator type: Round button
• Illumination type and color: LED, White
• Illumination voltage: 3.3VDC nominal
• Operating temperature range: -25°C to 50°C
• Mounting type: Panel Mount, Front
• RoHS compliance: ROHS3 Compliant

Differing Parameters (Design Considerations):

• Panel cutout diameter: KB26CKG01-6B-JB requires 12.30mm; YB26CKG01-6B-JB requires 16.00mm
• Termination style: KB26CKG01-6B-JB uses Solder Lug; YB26CKG01-6B-JB uses Solder with Quick Connect 0.110" (2.8mm)
• Mechanical life: KB26CKG01-6B-JB rated 100,000 cycles; YB26CKG01-6B-JB rated 200,000 cycles
• Product status: KB26CKG01-6B-JB is obsolete; YB26CKG01-6B-JB is active

Parameter Comparison

Engineering Selection Recommendations

The YB26CKG01-6B-JB is electrically and functionally equivalent to the KB26CKG01-6B-JB for applications requiring DPDT pushbutton switch functionality at 28V with white LED illumination. Both components maintain identical electrical specifications, operating temperature ranges, and regulatory compliance (ROHS3).

Selection of the YB26CKG01-6B-JB is supported by its active product status, ensuring continued availability and supply chain reliability compared to the obsolete KB26CKG01-6B-JB. The substitute part offers extended mechanical life (200,000 cycles versus 100,000 cycles), providing improved durability in high-cycle applications.

Physical integration requires evaluation of two design factors: panel cutout diameter (16.00mm for YB26CKG01-6B-JB versus 12.30mm for KB26CKG01-6B-JB) and termination interface (Quick Connect 0.110" versus Solder Lug). These differences necessitate mechanical redesign of the panel mounting interface and electrical connection methodology.

Frequently Asked Questions (FAQ)

Q: Can the YB26CKG01-6B-JB directly replace the KB26CKG01-6B-JB without modification?

A: Electrical substitution is valid; however, mechanical integration requires modification. The panel cutout diameter differs (16.00mm versus 12.30mm), and the termination style changes from Solder Lug to Quick Connect 0.110". Panel drilling and electrical connection redesign are necessary.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is based on matching DPDT circuit configuration, On-On switch function, 0.4VA current rating, 28V AC/DC voltage rating, round button actuator, white LED illumination at 3.3VDC, and identical operating temperature range (-25°C to 50°C). These parameters ensure functional equivalence in the application circuit.

Q: Does the YB26CKG01-6B-JB offer any performance advantages?

A: The YB26CKG01-6B-JB provides extended mechanical life (200,000 cycles versus 100,000 cycles), offering improved longevity in repetitive switching applications. Both parts maintain identical electrical specifications and regulatory compliance.

Q: Are there compliance or certification differences between these parts?

A: Both components are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. No compliance or certification differences exist between the KB26CKG01-6B-JB and YB26CKG01-6B-JB.

Q: What inventory status should influence component selection?

A: The KB26CKG01-6B-JB is classified as obsolete with 938 units in stock. The YB26CKG01-6B-JB is active with 882 units available. For long-term supply assurance, the active status of YB26CKG01-6B-JB supports continued design support and future procurement.
