Key Parameters

Substitute Part Grouping Explanation

Substitution of the GLAA20K8B is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Circuit configuration: DPDT
• Switch function: On-Momentary
• Current rating: 6A AC / 550mA DC
• Voltage rating: 120V AC / 125V DC

Mechanical Equivalence Criteria:

• Actuator type: Spring, Cat Whisker
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Operating force: 10gfm
• Operating position: 18°
• Pretravel: 18°
• Differential travel: 8°

Environmental & Compliance Criteria:

• Ingress protection: IP67
• Operating temperature range: -25°C to 85°C
• Mechanical life: 15,000,000 cycles
• RoHS compliance: Required
• Moisture sensitivity: MSL 1

The GLAA20K8C meets all substitution criteria and is classified as an active product, making it the direct equivalent for the obsolete GLAA20K8B.

Parameter Comparison
