Substitute Part Grouping Explanation

Substitution of the KB15CKG01-6G-JB is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Circuit configuration must remain SPDT
• Switch function must be On-Mom (momentary operation)
• Current rating must support minimum 0.4VA at AC/DC
• Voltage rating must support minimum 28V AC/DC
• Illumination type and color must match (LED, Blue)

Mechanical Equivalence Criteria:

• Mounting type must be Panel Mount, Front
• Actuator type must be Round Button
• Operating temperature range must encompass -25°C to 50°C
• Termination compatibility with circuit board design

Compliance Criteria:

• RoHS3 compliance required
• Moisture Sensitivity Level 1 (Unlimited)

The YB15CKG01-6G-JB meets all electrical and mechanical substitution criteria while offering enhanced mechanical durability and active product status.

Parameter Comparison

Engineering Selection Recommendations

The YB15CKG01-6G-JB is the direct substitute for KB15CKG01-6G-JB based on electrical and mechanical equivalence. Both components maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory continuity.

The substitute part offers extended mechanical life (1,000,000 cycles versus 100,000 cycles) and active product status, providing improved long-term availability and supply chain reliability. The YB series incorporates stainless steel construction, enhancing durability in operational environments.

Panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical panel modification. Termination style transitions from solder lug to solder with quick connect 0.110" (2.8mm) option, necessitating circuit board connection redesign. Illumination voltage decreases from 3.6 VDC to 3.3 VDC nominal, requiring circuit verification to confirm LED drive circuit compatibility within the specified tolerance range.

Frequently Asked Questions (FAQ)

Q: Can YB15CKG01-6G-JB directly replace KB15CKG01-6G-JB without circuit modification?

A: Electrical substitution is direct. Mechanical integration requires panel cutout enlargement from 12.30mm to 16.00mm diameter. Termination style change from solder lug to solder/quick connect requires circuit board connection redesign. Illumination voltage tolerance (3.3 VDC versus 3.6 VDC nominal) must be verified against existing LED drive circuit specifications.

Q: What are the key differences between these two part numbers?

A: Primary differences include panel cutout diameter (12.30mm versus 16.00mm), termination style (solder lug versus solder/quick connect), mechanical life rating (100,000 versus 1,000,000 cycles), illumination voltage nominal (3.6 VDC versus 3.3 VDC), and product status (obsolete versus active). Electrical specifications, circuit configuration, and voltage ratings remain equivalent.

Q: Is the illumination voltage difference significant for substitution?

A: The 0.3 VDC difference in nominal illumination voltage (3.6 VDC to 3.3 VDC) must be evaluated against the LED drive circuit design. Verify that the existing circuit can operate reliably within the YB15CKG01-6G-JB specification of 3.3 VDC nominal illumination voltage.

Q: What panel modifications are required for YB15CKG01-6G-JB installation?

A: The panel cutout diameter must be enlarged from 12.30mm to 16.00mm to accommodate the substitute part's larger mounting diameter. This modification is necessary for proper mechanical fit and panel mount security.

Q: Are both parts RoHS3 compliant?

A: Yes, both KB15CKG01-6G-JB and YB15CKG01-6G-JB are ROHS3 compliant with identical moisture sensitivity level ratings (MSL 1 - Unlimited), ensuring regulatory equivalence.
