Key Parameters

Substitute Part Grouping Explanation

The YB26CKW01-6B-JB qualifies as a functional substitute based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Manufacturer: NKK Switches (same manufacturer ensures design compatibility)
• Circuit Configuration: DPDT (identical switching topology)
• Switch Function: On-On (same operational mode)
• Voltage Rating - AC: 125V (identical AC rating)
• Voltage Rating - DC: 30V (identical DC rating)
• Mounting Type: Panel Mount, Front (same physical installation method)
• Illumination Type & Color: LED, White (identical indicator specification)
• Illumination Voltage: 3.3VDC (identical LED supply voltage)
• Actuator Type: Round, Button (same user interface)
• Operating Temperature Range: -25°C to 50°C (identical thermal operating window)
• RoHS Status: ROHS3 Compliant (equivalent environmental compliance)

Differing Parameters (Acceptable for Substitution):

• Current Rating: YB26CKW01-6B-JB rated 3A vs. KB26CKW01-6B-JB rated 1A (higher rating provides margin)
• Mechanical Life: YB26CKW01-6B-JB rated 200,000 cycles vs. KB26CKW01-6B-JB rated 100,000 cycles (enhanced durability)
• Electrical Life: YB26CKW01-6B-JB rated 100,000 cycles vs. KB26CKW01-6B-JB rated 50,000 cycles (enhanced durability)
• Termination Style: YB26CKW01-6B-JB offers Solder and Quick Connect options vs. KB26CKW01-6B-JB Solder Lug only (requires connector compatibility verification)
• Panel Cutout Dimensions: YB26CKW01-6B-JB requires 16.00mm circular cutout vs. KB26CKW01-6B-JB requires 12.30mm (mechanical panel modification required)
• Product Status: YB26CKW01-6B-JB is Active (ongoing availability)

Parameter Comparison

Engineering Selection Recommendations

The YB26CKW01-6B-JB is suitable as a substitute for KB26CKW01-6B-JB applications based on electrical equivalence and enhanced performance characteristics. The substitute part maintains identical voltage and switching specifications while providing higher current capacity (3A vs. 1A) and extended mechanical/electrical life ratings.

Selection of YB26CKW01-6B-JB requires evaluation of two mechanical factors:

1. Panel Cutout Compatibility: The substitute requires a 16.00mm circular cutout versus the original 12.30mm. Panel modification or adapter hardware may be necessary depending on existing installation geometry.

2. Termination Compatibility: The substitute offers both Solder and Quick Connect termination options. Existing wiring harnesses designed for Solder Lug termination require connector adaptation or rewiring to accommodate the Quick Connect option.

Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental consistency. The active product status of YB26CKW01-6B-JB provides long-term supply chain stability compared to the obsolete KB26CKW01-6B-JB.

Frequently Asked Questions (FAQ)

Q: Can YB26CKW01-6B-JB directly replace KB26CKW01-6B-JB without modifications?

A: Electrical substitution is direct. Mechanical integration requires panel cutout enlargement from 12.30mm to 16.00mm diameter and termination connector adaptation from Solder Lug to Solder or Quick Connect options.

Q: What is the impact of the higher current rating (3A vs. 1A) on system design?

A: The 3A rating of YB26CKW01-6B-JB provides additional safety margin for the same 1A application. No circuit redesign is required; the substitute operates within the original 1A specification with improved reliability headroom.

Q: Are the illumination specifications identical between both parts?

A: Yes. Both parts feature white LED illumination at 3.3VDC nominal voltage. LED brightness and color characteristics are equivalent.

Q: What is the significance of the extended mechanical and electrical life ratings?

A: YB26CKW01-6B-JB provides 200,000 mechanical cycles and 100,000 electrical cycles versus 100,000 and 50,000 respectively for KB26CKW01-6B-JB. This represents doubled durability for both metrics, extending component service life in high-cycle applications.

Q: Are there supply chain advantages to selecting YB26CKW01-6B-JB?

A: Yes. YB26CKW01-6B-JB carries Active product status with current manufacturing and distribution, whereas KB26CKW01-6B-JB is Obsolete. Active status ensures ongoing availability and pricing stability.

Q: Do both parts meet the same environmental compliance standards?

A: Yes. Both parts are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), ensuring equivalent environmental and handling requirements.
