KB16CKW01-FF Equivalent & Substitute Parts

Part Overview

The KB16CKW01-FF 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, with a circular 12.30mm panel cutout for front-mounted installation. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing maintenance, repair, and design continuity in applications where this switch was originally specified.

Substitute Part Grouping Explanation

Substitution of the KB16CKW01-FF is determined by the following critical parameters that must remain compatible:

Mandatory Compatibility Parameters:

  • Circuit configuration (SPDT)
  • Switch function (On-On)
  • Voltage ratings (125V AC minimum, 30V DC minimum)
  • Mounting type (Panel Mount, Front)
  • Actuator type (Round, Button)
  • Operating temperature range (-25°C to 70°C minimum)
  • RoHS3 compliance status

Allowable Variation Parameters:

  • Current rating (substitute must meet or exceed 1A)
  • Mechanical and electrical life cycles (substitute must meet or exceed specified values)
  • Panel cutout diameter (physical installation considerations)
  • Termination style (circuit integration considerations)
  • Actuator color and finish

The YB16CKW01-FB meets all mandatory compatibility requirements while exceeding performance specifications in current rating (3A), mechanical life (200,000 cycles), and electrical life (100,000 cycles). The larger panel cutout diameter (16.00mm) and modified termination style require mechanical and electrical integration review during substitution.

Engineering Selection Recommendations

The YB16CKW01-FB is a functionally compatible substitute for the obsolete KB16CKW01-FF based on electrical and mechanical equivalence. Both components maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental consistency.

The substitute part provides enhanced performance characteristics: 3A current capacity (versus 1A), 200,000 mechanical cycle life (versus 100,000), and 100,000 electrical cycle life (versus 50,000). These improvements support extended service life and higher-load applications without compromising the original design intent.

Physical integration requires consideration of the larger panel cutout diameter (16.00mm versus 12.30mm), which necessitates panel modification or adapter consideration. The modified termination style (Solder with Quick Connect option versus Solder Lug only) provides circuit integration flexibility but requires verification of PCB or harness compatibility.

The active product status of YB16CKW01-FB ensures ongoing availability and supply chain continuity compared to the obsolete KB16CKW01-FF.

Frequently Asked Questions (FAQ)

Q: Can YB16CKW01-FB directly replace KB16CKW01-FF without any modifications?

A: Electrical and functional compatibility is confirmed. Physical installation requires panel cutout enlargement from 12.30mm to 16.00mm diameter. Termination compatibility must be verified against existing circuit connections (Solder Lug versus Solder/Quick Connect).

Q: What are the key differences between these two switches?

A: The primary differences are current rating (1A to 3A), mechanical life (100,000 to 200,000 cycles), electrical life (50,000 to 100,000 cycles), panel cutout size (12.30mm to 16.00mm), and termination options. All electrical parameters (voltage, circuit configuration, switching function) remain identical.

Q: Is the YB16CKW01-FB suitable for the same voltage and current applications?

A: Yes. The YB16CKW01-FB maintains 125V AC and 30V DC ratings identical to the KB16CKW01-FF. The higher current rating (3A) provides additional capacity margin for the same application requirements.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: Are there packaging or inventory considerations for substitution?

A: The KB16CKW01-FF is supplied in standard packaging with 951 units in stock (obsolete status). The YB16CKW01-FB is supplied in bulk packaging with 912 units in stock (active product status), ensuring continued availability.

Q: Does the substitute part include tactile feedback?

A: The YB16CKW01-FB includes tactile feedback as a feature. The KB16CKW01-FF does not list this feature in its specifications.
