Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB16CKW01-6F-JB is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Voltage ratings (125V AC minimum, 30V DC minimum)
• Mounting type (Panel Mount, Front)
• Actuator type (Round, Button)
• Illumination type and color (LED, Green)
• Illumination voltage (3.3 VDC)
• Operating temperature range (-25°C to 50°C minimum)
• Compliance certifications (RoHS3, REACH Unaffected)

Allowable Variations:

• Current rating may exceed 1A (higher current capability is acceptable)
• Mechanical and electrical life may exceed specified minimums
• Panel cutout diameter may differ if mechanical redesign is acceptable
• Termination style may differ if electrical redesign is acceptable
• Packaging format may vary

The substitute part YB16WCKW01-6F-JB meets all mandatory matching parameters while exceeding performance specifications in current rating, mechanical life, and electrical life.

Parameter Comparison

Engineering Selection Recommendations

The YB16WCKW01-6F-JB is a direct functional substitute for the obsolete KB16CKW01-6F-JB. Both components maintain identical electrical specifications for voltage and circuit configuration, with the substitute offering enhanced performance characteristics. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Both parts maintain full RoHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and legacy system replacements. The substitute's higher current rating (3A versus 1A) and extended mechanical/electrical life (200,000/100,000 cycles versus 100,000/50,000 cycles) provide additional design margin without compromising compatibility.

Mechanical integration requires evaluation of panel cutout dimensions: the main part specifies 12.30mm diameter while the substitute requires 16.00mm diameter. Termination style differs (Solder Lug versus Solder/Quick Connect), necessitating electrical connection redesign. These mechanical and electrical interface changes must be accommodated during substitution implementation.

Frequently Asked Questions (FAQ)

Q: Can YB16WCKW01-6F-JB directly replace KB16CKW01-6F-JB without any modifications?

A: Electrical and functional compatibility is complete. However, mechanical integration requires panel cutout modification from 12.30mm to 16.00mm diameter, and termination connections must be redesigned to accommodate the substitute's Solder/Quick Connect termination versus the original Solder Lug configuration.

Q: What is the current rating difference, and does it affect circuit design?

A: The substitute provides 3A capacity versus the original 1A rating. This higher current capability is a performance enhancement that does not require circuit redesign. Existing 1A circuits operate safely within the substitute's 3A maximum rating.

Q: Are both parts compliant with current regulatory standards?

A: Both KB16CKW01-6F-JB and YB16WCKW01-6F-JB maintain RoHS3 compliance and REACH unaffected status, satisfying current regulatory requirements for electronic component use.

Q: Why does the substitute have different mechanical life specifications?

A: The YB16WCKW01-6F-JB is rated for 200,000 mechanical cycles and 100,000 electrical cycles, compared to 100,000 and 50,000 cycles respectively for the original part. This represents improved durability and extended operational life in the substitute design.

Q: What packaging differences exist between these parts?

A: The KB16CKW01-6F-JB uses standard packaging, while YB16WCKW01-6F-JB is supplied in Tray packaging. This difference affects receiving, storage, and handling procedures but does not impact component functionality.

Q: Is the illumination voltage identical between both parts?

A: Yes, both parts operate at 3.3 VDC nominal illumination voltage with LED green color, ensuring identical visual indication behavior in circuit applications.
