Key Parameters

Substitute Part Grouping Explanation

Substitute components for the KB01KW01-28-JC must satisfy the following critical parameters to ensure functional compatibility:

• Voltage Rating: 28V operation
• Indicator Type: Panel indicator with visual output capability
• Termination: Solder lug connection
• Panel Integration: Round cutout, 0.48" (12.19mm) diameter
• Regulatory Compliance: RoHS3 and REACH compliance maintained

The substitute part YB01KW01-5C24-JB is classified as a panel indicator from NKK Switches. While this component shares the same manufacturer and panel indicator category, direct electrical and mechanical parameter alignment must be verified against the original specification requirements for 28V incandescent operation.

Parameter Comparison

Engineering Selection Recommendations

The KB01KW01-28-JC is an obsolete component with active inventory availability (803 pcs). The substitute YB01KW01-5C24-JB is an active product from the same manufacturer with higher inventory levels (1114 pcs).

Selection between these components must be based on:

1. Voltage Compatibility: Verify that YB01KW01-5C24-JB operates at 28V as required by the original circuit design
2. Mechanical Fit: Confirm panel cutout dimensions and lens geometry match the 0.48" (12.19mm) round cutout specification
3. Termination Compatibility: Ensure solder lug termination is maintained for circuit board integration
4. Regulatory Compliance: Confirm RoHS3 and REACH compliance status of the substitute part

Both components maintain MSL 1 (Unlimited) moisture sensitivity rating, supporting use in standard industrial environments without special handling requirements.

Frequently Asked Questions (FAQ)

Q: Why is the KB01KW01-28-JC classified as obsolete?

A: The KB01KW01-28-JC is an obsolete product per NKK Switches' product lifecycle status. Obsolete classification indicates the manufacturer has discontinued production and support for this component.

Q: What are the critical parameters for substitution?

A: Substitutes must maintain 28V voltage rating, round panel cutout geometry (0.48" / 12.19mm), solder lug termination, and red indicator output. Mechanical fit and electrical performance are interdependent.

Q: Is the YB01KW01-5C24-JB a direct replacement?

A: The YB01KW01-5C24-JB is an active panel indicator from NKK Switches. Functional equivalence requires verification of voltage rating, panel cutout dimensions, lens specifications, and termination style against the original KB01KW01-28-JC requirements.

Q: What compliance certifications apply to both parts?

A: The KB01KW01-28-JC is ROHS3 compliant and REACH unaffected. Compliance status for YB01KW01-5C24-JB must be confirmed with the manufacturer or distributor technical documentation.

Q: Are there inventory considerations for component selection?

A: The KB01KW01-28-JC has 803 pcs available as new original stock. The YB01KW01-5C24-JB has 1114 pcs available. Inventory availability should be evaluated against project timeline and volume requirements.

Q: What termination method is used for circuit board integration?

A: The KB01KW01-28-JC uses solder lug termination. Substitute components must maintain this termination style for compatibility with existing PCB designs and assembly processes.
