Substitute Part Grouping Explanation

Substitution of the SI-LS31PBE is based on functional equivalence within the Banner Engineering Corporation product line. The identified substitute SI-LS83PBE shares the same manufacturer origin, ensuring design compatibility and interchangeability within systems originally specified for the SI-LS31PBE. The substitution logic prioritizes:

• Manufacturer consistency (Banner Engineering Corporation)
• Switch function classification (interlock/safety switching)
• Mechanical interface compatibility (panel disconnect actuator type)
• Electrical performance parameters (current and voltage ratings)
• Environmental protection standards (ingress protection rating)
• Industry certifications and approvals

Parameter Comparison

Engineering Selection Recommendations

The SI-LS83PBE is the designated substitute for the obsolete SI-LS31PBE. Selection of this substitute is supported by:
