KB15RKW01-05-FF Equivalent & Substitute Parts

Part Overview

The KB15RKW01-05-FF is an illuminated pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 1A current rating at 125V AC. This component is designed for panel-mount front installation with incandescent green illumination at 5 VAC. The product is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and new design applications where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB15RKW01-05-FF is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom)
• Mounting type (Panel Mount, Front)
• Voltage rating (125V AC minimum)
• Operating temperature range (-25°C to 50°C)
• RoHS3 compliance

Allowable Variation Parameters:

• Current rating: Substitute must equal or exceed 1A
• Illumination type: LED substitutes incandescent with equivalent green indication
• Illumination voltage: 5 VDC acceptable as functional equivalent to 5 VAC
• Panel cutout diameter: Larger diameter acceptable with mechanical adaptation
• Mechanical and electrical life: Higher values acceptable
• Termination style: Variation permitted if electrical connection is maintained

The YB15RKW01-5F05-JF meets all mandatory compatibility requirements while providing enhanced performance characteristics in current rating, mechanical life, and electrical life.

Parameter Comparison

Engineering Selection Recommendations

The YB15RKW01-5F05-JF is a functionally equivalent substitute for the obsolete KB15RKW01-05-FF. Both components maintain identical electrical specifications for voltage and circuit configuration, with the substitute providing enhanced current capacity (3A versus 1A) and significantly extended mechanical life (1,000,000 versus 100,000 cycles).

The substitute component is currently in active production status, ensuring long-term availability and supply chain continuity. Both parts maintain ROHS3 compliance and identical operating temperature specifications, supporting direct functional replacement in existing applications.

The primary design consideration is panel cutout diameter: the substitute requires a 16.00mm circular opening compared to the original 12.30mm specification. This necessitates mechanical panel modification or use of an adapter bezel for installation in existing enclosures designed for the original component.

Illumination technology transition from incandescent to LED provides improved reliability and reduced power consumption while maintaining green visual indication. The shift from 5 VAC to 5 VDC illumination voltage requires verification of available power supply architecture in the host system.

Frequently Asked Questions (FAQ)

Q: Can the YB15RKW01-5F05-JF directly replace the KB15RKW01-05-FF without modification?

A: Electrical and functional replacement is direct. Mechanical panel installation requires adaptation due to increased cutout diameter (16.00mm versus 12.30mm). Illumination voltage change from 5 VAC to 5 VDC must be accommodated by the host circuit.

Q: What is the significance of the current rating increase from 1A to 3A?

A: The substitute component supports higher load currents while maintaining identical voltage specifications. This provides design margin for applications approaching the original 1A limit and enables use in higher-current switching applications without component change.

Q: Are there compatibility concerns with the illumination technology change?

A: LED illumination (YB15RKW01-5F05-JF) replaces incandescent illumination (KB15RKW01-05-FF). Both provide green indication. The voltage change from 5 VAC to 5 VDC requires host circuit verification. LED operation typically requires lower current than incandescent equivalents.

Q: What mechanical considerations apply to panel installation?

A: The substitute component requires a 16.00mm diameter circular panel cutout versus 12.30mm for the original. Existing panels designed for the KB15RKW01-05-FF require enlargement of the cutout opening or installation of an adapter bezel to accommodate the larger diameter.

Q: How do the mechanical and electrical life ratings affect component selection?

A: The substitute provides 10x greater mechanical life (1,000,000 cycles) and 2x greater electrical life (100,000 cycles) compared to the original. These enhanced ratings support extended service intervals and higher-cycle-count applications.

Q: Is the substitute component subject to the same regulatory compliance as the original?

A: Both components maintain ROHS3 compliance and identical operating temperature specifications (-25°C to 50°C). The substitute is currently in active production, ensuring ongoing compliance with current regulatory requirements.
