KB15RKW01-GG Equivalent & Substitute Parts

Part Overview

The KB15RKW01-GG is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 1A current rating at 125V AC. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The switch is designed for standard panel mount, front installation with solder lug termination and blue rectangular button actuator.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical Compatibility Requirements:

• Circuit configuration must remain SPDT
• Switch function must remain On-Mom (momentary operation)
• Voltage ratings must meet or exceed: 125V AC and 30V DC
• Current rating must meet or exceed: 1A AC/DC

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Front
• Actuator type must be Rectangular, Button
• Panel cutout dimensions must accommodate the substitute part's physical requirements

Environmental & Compliance Requirements:

• Operating temperature range must encompass -25°C to 70°C
• RoHS3 compliance required
• Moisture Sensitivity Level must be 1 (Unlimited)

The YB15RKW01-GB meets all electrical compatibility criteria with enhanced current rating (3A), superior mechanical life (1,000,000 cycles vs. 100,000 cycles), and extended electrical life (100,000 cycles vs. 50,000 cycles). However, mechanical substitution requires panel cutout modification due to increased diameter (16.00mm vs. 12.30mm) and termination style change (Solder, Quick Connect vs. Solder Lug).

Parameter Comparison

Engineering Selection Recommendations

The YB15RKW01-GB is an active product substitute for the obsolete KB15RKW01-GG. Both components maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility.

Electrical substitution is direct: the YB15RKW01-GB exceeds the current rating requirement (3A vs. 1A) while maintaining identical voltage specifications (125V AC, 30V DC) and circuit configuration (SPDT, On-Mom).

Mechanical substitution requires design modification. The panel cutout diameter increases from 12.30mm to 16.00mm, necessitating panel drilling adjustment. Termination style changes from solder lug to solder with quick connect 0.110" (2.8mm) terminals, requiring circuit board trace and connector redesign.

The YB15RKW01-GB provides superior operational longevity with 10-fold increase in mechanical life (1,000,000 vs. 100,000 cycles) and doubled electrical life (100,000 vs. 50,000 cycles), supporting extended system service life.

Frequently Asked Questions (FAQ)

Q: Can YB15RKW01-GB directly replace KB15RKW01-GG without modification?

A: Electrical substitution is direct. Mechanical substitution requires panel cutout modification (12.30mm to 16.00mm diameter) and termination redesign (solder lug to quick connect terminals).

Q: Are voltage and current ratings compatible?

A: Yes. The YB15RKW01-GB maintains 125V AC and 30V DC ratings while providing 3A current capacity, exceeding the 1A requirement of KB15RKW01-GG.

Q: What is the impact of different termination styles?

A: KB15RKW01-GG uses solder lug termination for direct PCB soldering. YB15RKW01-GB uses solder with quick connect 0.110" (2.8mm) terminals, requiring connector interface modification on the circuit board.

Q: Are both parts RoHS compliant?

A: Yes. Both KB15RKW01-GG and YB15RKW01-GB are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: What are the operational life differences?

A: KB15RKW01-GG provides 100,000 mechanical cycles and 50,000 electrical cycles. YB15RKW01-GB provides 1,000,000 mechanical cycles and 100,000 electrical cycles, representing significant durability improvement.

Q: Is the actuator color difference significant?

A: KB15RKW01-GG features solid blue actuator. YB15RKW01-GB features blue with white filter/diffuser. This is a visual distinction with no electrical impact.
