KB16RKW01 Equivalent & Substitute Parts
Part Overview
The KB16RKW01 is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with On-On switching function. This component is rated for 1A at 125V AC and 30V DC, designed for standard panel mount front installation with solder lug termination. The product is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and new design implementations where equivalent functionality is required.

Substitute Part Grouping Explanation
Substitution of the KB16RKW01 is determined by the following critical parameters:
Electrical Compatibility Requirements:
- Circuit configuration must remain SPDT
- Switch function must be On-On
- Voltage ratings must meet or exceed: 125V AC and 30V DC
- Current rating must support the application load (minimum 1A)
Mechanical Compatibility Requirements:
- Mounting type must be Panel Mount, Front
- Actuator type must be Plunger for Cap
- Operating temperature range must encompass -25°C ~ 70°C
Environmental & Compliance Requirements:
- RoHS3 compliance required
- MSL rating of 1 (Unlimited) acceptable
The YB16RKW01 qualifies as a substitute based on matching circuit configuration (SPDT), switch function (On-On), voltage ratings (125V AC / 30V DC), mounting type (Panel Mount, Front), actuator type (Plunger for Cap), temperature range (-25°C ~ 70°C), and compliance certifications (ROHS3 Compliant, MSL 1).

Engineering Selection Recommendations
The YB16RKW01 is an active product from NKK Switches and serves as a direct functional substitute for the obsolete KB16RKW01. Both components maintain identical electrical specifications (SPDT, On-On, 125V AC / 30V DC), identical mounting configuration (Panel Mount, Front), and identical environmental compliance (ROHS3 Compliant, MSL 1).
The YB16RKW01 provides enhanced performance characteristics with higher current capacity (3A versus 1A), extended mechanical life (200,000 cycles versus 100,000 cycles), and extended electrical life (100,000 cycles versus 50,000 cycles). These improvements ensure greater reliability and longevity in applications.
Physical integration requires consideration of panel cutout dimensions: the YB16RKW01 requires a 16.00mm diameter circular cutout compared to the KB16RKW01's 12.30mm diameter. Termination differs between solder lug (KB16RKW01) and solder with quick connect option (YB16RKW01), necessitating circuit board layout verification.
Frequently Asked Questions (FAQ)
Q: Can the YB16RKW01 directly replace the KB16RKW01 in existing designs?
A: Electrical and functional compatibility is confirmed. Physical integration requires verification of panel cutout dimensions (16.00mm for YB16RKW01 versus 12.30mm for KB16RKW01) and termination method compatibility (solder lug versus solder/quick connect).
Q: What are the key differences between these components?
A: The YB16RKW01 offers higher current capacity (3A versus 1A), extended mechanical life (200,000 versus 100,000 cycles), and extended electrical life (100,000 versus 50,000 cycles). Panel cutout diameter differs (16.00mm versus 12.30mm), and termination options differ (solder lug versus solder/quick connect).
Q: Are both components RoHS compliant?
A: Yes, both KB16RKW01 and YB16RKW01 are ROHS3 compliant with MSL rating of 1 (Unlimited).
Q: What is the operating temperature range for both components?
A: Both components operate across the identical temperature range of -25°C to 70°C.
Q: Does the higher current rating of the YB16RKW01 affect compatibility?
A: Higher current rating indicates enhanced capability and does not create incompatibility. Applications rated for 1A operation remain fully compatible with the 3A-rated YB16RKW01.
