Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the KB15RKW01-5C-JC is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must remain SPDT
• Voltage ratings must meet or exceed 125V AC and 30V DC
• Current rating must support the application load (minimum 1A)
• Illumination type and voltage must match (LED, Red, 1.9 VDC)

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Front
• Actuator type must be Rectangular, Button
• Operating temperature range must encompass -25°C to 50°C
• Switch function must be On-Mom (momentary)

Regulatory & Environmental Requirements:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) acceptable
• REACH Unaffected status required

The YB15RKW01-5C-JC qualifies as a substitute part because it maintains SPDT circuit configuration, panel-mount front installation, rectangular button actuator, red LED illumination at 1.9 VDC, identical voltage ratings, matching operating temperature range, and equivalent regulatory compliance. The higher current rating (3A versus 1A) and enhanced mechanical/electrical life cycles represent performance improvements that do not compromise backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

The YB15RKW01-5C-JC represents the primary substitute for the obsolete KB15RKW01-5C-JC. Selection is supported by the following factors:

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH Unaffected status, ensuring continued compliance with current environmental and hazardous substance regulations.

Product Lifecycle Status: The substitute part carries Active product status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Electrical Performance: The substitute maintains identical voltage ratings (125V AC / 30V DC) and illumination specifications (LED, Red, 1.9 VDC), ensuring direct functional equivalence in existing circuit designs.

Mechanical Durability: The substitute demonstrates enhanced mechanical life (1,000,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles), providing extended operational reliability without design modification.

Physical Integration: Panel cutout diameter increases from 12.30mm to 16.00mm. This dimensional change requires panel modification or use of adapter hardware for direct mechanical replacement in existing installations.

Termination Compatibility: The main part features solder lug termination, while the substitute offers both solder and quick connect options. Solder lug termination remains available on the substitute, maintaining electrical connection compatibility.

Frequently Asked Questions (FAQ)

Q: Can the YB15RKW01-5C-JC directly replace the KB15RKW01-5C-JC in existing assemblies?

A: Electrical and functional replacement is direct. Mechanical replacement requires panel cutout modification due to diameter increase from 12.30mm to 16.00mm. Termination compatibility is maintained through solder lug options on the substitute part.

Q: What is the significance of the higher current rating (3A versus 1A) on the substitute part?

A: The 3A rating on YB15RKW01-5C-JC provides increased current-handling capacity. This does not affect compatibility with applications designed for 1A operation, as the substitute can safely handle lower current loads. Applications requiring higher current capacity benefit from the enhanced rating.

Q: Are the voltage ratings identical between the main part and substitute?

A: Yes. Both components maintain 125V AC and 30V DC voltage ratings, ensuring direct electrical compatibility in circuits designed for these specifications.

Q: What packaging differences exist between these parts?

A: The main part KB15RKW01-5C-JC is supplied with standard packaging. The substitute YB15RKW01-5C-JC is supplied in bulk packaging. Packaging selection does not affect component performance or electrical characteristics.

Q: How do the mechanical and electrical life ratings compare?

A: The substitute part demonstrates superior durability with 1,000,000 mechanical cycles (versus 100,000) and 100,000 electrical cycles (versus 50,000). These enhancements extend component service life without requiring design changes.

Q: Is the illumination specification identical on both parts?

A: Yes. Both components feature LED red illumination at 1.9 VDC nominal voltage, ensuring identical visual indication performance and power supply requirements.

Q: What termination options are available on the substitute part?

A: The YB15RKW01-5C-JC offers both solder lug and quick connect (0.110" / 2.8mm) termination options. The solder lug option maintains compatibility with the main part's termination method.
