Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB01KW01-05-EB is determined by the following critical parameters:

• Voltage Rating: 5V AC operation
• Current Rating: 115mA maximum
• Lamp Type: Incandescent technology
• Lamp Color: Yellow
• Lens Color: Yellow
• Lens Transparency: Diffused optical properties
• Panel Cutout Dimensions: 0.48" (12.19mm) round opening
• Lens Size: 11.60mm
• Lens Style: Square with flat top configuration

The substitute part YB01KW01-5D05-JD from NKK Switches shares the same manufacturer lineage and operates within compatible electrical parameters. Both components are designed for panel-mount illuminated pushbutton applications and maintain equivalent mechanical interfaces for the specified panel cutout dimensions.

Parameter Comparison

Engineering Selection Recommendations

The KB01KW01-05-EB is classified as obsolete, necessitating component replacement for new procurement and long-term system support. The YB01KW01-5D05-JD is an active product from the same manufacturer and maintains ROHS3 compliance and MSL 1 rating consistent with the original component.

Selection of substitute components must account for the voltage supply architecture of the target application. The original KB01KW01-05-EB operates on 5V AC, while the YB01KW01-5D05-JD is specified for 5V DC operation. This distinction requires verification of the power supply configuration in the host system before component substitution.

Both components carry EAR99 export classification and are subject to identical regulatory frameworks.

Frequently Asked Questions (FAQ)

Q: Can the YB01KW01-5D05-JD directly replace the KB01KW01-05-EB in existing assemblies?

A: Direct mechanical substitution is possible due to equivalent panel cutout dimensions (0.48" / 12.19mm round opening). However, electrical compatibility depends on the power supply type. The original part requires 5V AC, while the substitute requires 5V DC. Verify the power supply configuration before substitution.

Q: What is the significance of the resistor integrated into the YB01KW01-5D05-JD?

A: The integrated resistor in the YB01KW01-5D05-JD is designed for DC operation and current limiting. This differs from the AC-rated KB01KW01-05-EB, which does not include this component.

Q: Are both components RoHS compliant?

A: The KB01KW01-05-EB is ROHS3 compliant. RoHS compliance status for the YB01KW01-5D05-JD is not specified in the provided data.

Q: What is the MSL rating, and does it affect substitution?

A: Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling. This parameter does not present a substitution barrier.

Q: Are there inventory considerations for component selection?

A: The KB01KW01-05-EB has 678 pieces in stock as new original inventory. The YB01KW01-5D05-JD has 1126 pieces available. Inventory availability should be evaluated against project timelines and long-term support requirements.
