Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete GKLA2D4S2 is based on the following criteria derived from available technical parameters:

Primary Substitution Basis:

• Functional classification as an interlock safety switching device
• RoHS compliance status alignment
• Moisture sensitivity level compatibility (MSL 1)
• Active product status ensuring continued availability

The substitute part SG-B1-MA-G5 (Panasonic Industrial Automation Sales) meets these substitution criteria through equivalent environmental and compliance specifications. Both components maintain MSL 1 rating and RoHS compliance, enabling direct functional replacement in applications requiring interlock safety switching.
