Substitute Part Grouping Explanation

Substitution eligibility for the KB15RKW01-EB is determined by the following critical parameters:

Mandatory Matching Parameters:

  • Circuit Configuration: SPDT
  • Switch Function: On-Mom (Momentary)
  • Voltage Rating - AC: 125V
  • Voltage Rating - DC: 30V
  • Mounting Type: Panel Mount, Front
  • Actuator Type: Rectangular, Button
  • Operating Temperature Range: -25°C ~ 70°C
  • RoHS Compliance: ROHS3 Compliant

Allowable Variation Parameters:

  • Current Rating: May be equal to or greater than 1A
  • Mechanical Life: May be equal to or greater than 100,000 cycles
  • Electrical Life: May be equal to or greater than 50,000 cycles
  • Termination Style: Alternative termination methods acceptable if panel mount compatibility maintained
  • Panel Cutout Dimensions: Larger cutout dimensions acceptable with mechanical adapter consideration

The YB15RKW01-EB meets substitution criteria through matching circuit configuration, switch function, voltage ratings, mounting type, actuator type, temperature range, and RoHS compliance. The substitute part exceeds the original specifications in current rating (3A vs 1A), mechanical life (1,000,000 vs 100,000 cycles), and electrical life (100,000 vs 50,000 cycles), making it a direct upgrade path.

Engineering Selection Recommendations

The YB15RKW01-EB is the designated substitute for the obsolete KB15RKW01-EB. Both components maintain identical electrical specifications for circuit configuration (SPDT), switch function (On-Mom), and voltage ratings (125V AC / 30V DC). Both components are ROHS3 compliant and REACH unaffected, satisfying regulatory requirements for equivalent applications.

The YB15RKW01-EB provides enhanced performance characteristics with increased current capacity (3A versus 1A), extended mechanical life (1,000,000 versus 100,000 cycles), and extended electrical life (100,000 versus 50,000 cycles). The substitute part maintains active product status, ensuring ongoing availability and supply chain continuity.

Physical integration considerations include panel cutout diameter increase from 12.30mm to 16.00mm and termination style modification from solder lug to solder with quick connect options. These differences require mechanical panel adapter evaluation and circuit connection method assessment during implementation.

Frequently Asked Questions (FAQ)

Q: Can YB15RKW01-EB directly replace KB15RKW01-EB without circuit modifications?

A: Electrical compatibility is confirmed through matching SPDT circuit configuration, On-Mom switch function, and identical voltage ratings (125V AC / 30V DC). Mechanical integration requires panel cutout diameter accommodation (16.00mm versus 12.30mm) and termination method compatibility assessment.

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

A: The primary differences are current rating (3A versus 1A), mechanical life (1,000,000 versus 100,000 cycles), electrical life (100,000 versus 50,000 cycles), panel cutout diameter (16.00mm versus 12.30mm), and termination style (solder with quick connect versus solder lug). The substitute part provides superior performance specifications.

Q: Is the YB15RKW01-EB suitable for applications originally designed for KB15RKW01-EB?

A: Yes, provided the application current requirement does not exceed 1A and the panel mechanical design accommodates the larger 16.00mm cutout diameter. The substitute part's enhanced electrical and mechanical life ratings make it suitable for equivalent or more demanding applications.

Q: What is the impact of the different panel cutout dimensions?

A: The YB15RKW01-EB requires a 16.00mm diameter circular cutout compared to the 12.30mm diameter of the KB15RKW01-EB. Panel modification or mechanical adapter implementation is necessary for physical installation.

Q: Are both parts RoHS and REACH compliant?

A: Yes, both KB15RKW01-EB and YB15RKW01-EB are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for equivalent component selection.

Q: What is the significance of the product status difference?

A: The KB15RKW01-EB is obsolete, indicating discontinued manufacturing and limited availability. The YB15RKW01-EB maintains active product status, ensuring reliable supply chain access and ongoing manufacturer support.
