Key Parameters

Substitute Part Grouping Explanation

Substitution of the UB201KW03CF-3JB is determined by the following critical parameters:

• Dual-color LED configuration (green and red)
• Electrical specifications: 4.6V green / 2.1V red forward voltage; 25mA green / 30mA red maximum current
• Physical form factor: 15.24mm x 15.00mm rectangular lens with flat top
• Diffused lens transparency with white lens color
• NKK Switches UB2 series compatibility

The identified substitute part UB201KW036CF-3JB maintains compatibility across these core parameters while offering improved product status and regulatory compliance.

Engineering Selection Recommendations

The UB201KW036CF-3JB serves as the direct substitute for the obsolete UB201KW03CF-3JB. Key advantages of this substitution include:

• Active product status ensures continued availability and manufacturer support
• ROHS3 compliance meets current environmental and regulatory requirements
• Maintained compatibility within the NKK Switches UB2 series
• Dual-color LED functionality preserved for green and red indication applications
• Tray packaging format supports standard component handling and assembly processes

Selection of the UB201KW036CF-3JB is appropriate for applications requiring replacement of the obsolete UB201KW03CF-3JB where regulatory compliance and long-term availability are considerations.

Frequently Asked Questions (FAQ)

Q: What makes UB201KW036CF-3JB a suitable substitute for UB201KW03CF-3JB?

A: Both parts are manufactured by NKK Switches within the UB2 series and provide dual-color LED panel indication with green and red lamp colors. The substitute maintains the same functional purpose and physical form factor required for panel-mount applications.

Q: Are the electrical specifications identical between these parts?

A: The provided data confirms both parts function as dual-color LED indicators. Specific voltage and current ratings for the substitute part were not provided in the available documentation; verification against the UB201KW036CF-3JB datasheet is recommended for critical applications.

Q: What is the significance of the RoHS compliance difference?

A: The main part (UB201KW03CF-3JB) is RoHS non-compliant, while the substitute (UB201KW036CF-3JB) is ROHS3 compliant. This distinction is relevant for applications subject to environmental regulations or customer requirements mandating RoHS compliance.

Q: Does packaging format affect substitution compatibility?

A: Packaging format (tray for the substitute) affects handling, storage, and assembly processes but does not impact electrical or mechanical compatibility. Verify that tray packaging aligns with your assembly workflow requirements.

Q: Why is the main part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The UB201KW036CF-3JB, with active product status, represents the current production alternative within the same product family.
