Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15CKW01-6F-JB is determined by the following critical parameters:

Core Functional Requirements:

• Circuit configuration must remain SPDT
• Switch function must be On-Mom (momentary operation)
• Mounting type must be Panel Mount, Front
• Actuator type must be Round, Button
• Illumination must be LED, Green at 3.3 VDC nominal

Electrical Compatibility Criteria:

• Voltage ratings must meet or exceed: 125V AC and 30V DC
• Current rating must meet or exceed: 1A (AC/DC)
• Operating temperature range must encompass or match: -25°C to 50°C

Mechanical and Physical Constraints:

• Panel cutout diameter compatibility is required
• Termination style must be compatible with existing circuit board design

The YB15CKW01-6F-JB qualifies as a substitute based on these parameters. While it features enhanced specifications (3A current rating, 1,000,000 mechanical cycles, 100,000 electrical cycles) and different termination options, it maintains all core functional requirements and exceeds the electrical performance envelope of the original part.

Parameter Comparison

Engineering Selection Recommendations

The YB15CKW01-6F-JB is a qualified substitute for the KB15CKW01-6F-JB based on the following engineering criteria:

Product Status Advantage: The substitute part is classified as Active, ensuring continued availability and supply chain stability compared to the obsolete main part.

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

Performance Enhancement: The substitute provides superior electrical and mechanical life ratings (100,000 and 1,000,000 cycles respectively versus 50,000 and 100,000 cycles), delivering extended operational reliability within the same functional envelope.

Physical Integration Consideration: The panel cutout diameter increases from 12.30mm to 16.00mm. This difference requires mechanical panel redesign or use of adapter hardware if retrofitting into existing enclosures.

Termination Compatibility: The substitute offers dual termination options (Solder and Quick Connect 0.110"). Solder lug termination remains available, maintaining compatibility with existing circuit board designs. Quick Connect termination provides alternative integration flexibility.

Frequently Asked Questions (FAQ)

Q: Can the YB15CKW01-6F-JB directly replace the KB15CKW01-6F-JB in existing designs?

A: Functional substitution is valid for electrical and control logic purposes. However, the 16.00mm panel cutout diameter of the substitute versus the 12.30mm diameter of the original requires mechanical panel modification or adapter hardware for physical installation.

Q: What are the key differences in electrical performance?

A: The substitute maintains identical voltage ratings (125V AC, 30V DC) and operating temperature range (-25°C to 50°C). The current rating increases from 1A to 3A, and both mechanical and electrical life cycles are significantly higher, providing enhanced durability for the same application envelope.

Q: Are both parts suitable for the same circuit applications?

A: Yes. Both parts feature identical SPDT circuit configuration, On-Mom switch function, and 3.3 VDC LED illumination. The substitute's higher current rating ensures compatibility with applications originally designed for the 1A-rated main part.

Q: What termination options are available with the substitute?

A: The YB15CKW01-6F-JB provides Solder and Quick Connect 0.110" (2.8mm) termination options. The original part features Solder Lug termination only. Solder termination on the substitute maintains compatibility with existing solder-based circuit board connections.

Q: Does the substitute meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, satisfying equivalent regulatory compliance for component selection in regulated applications.

Q: What is the inventory status of these parts?

A: The KB15CKW01-6F-JB (obsolete) has 948 pieces in stock. The YB15CKW01-6F-JB (active) has 1,149 pieces available, providing superior long-term supply assurance.
