Key Parameters

Substitute Part Grouping Explanation

Substitution of the GLFD01A2B is based on strict electrical and mechanical parameter matching within the Honeywell GLS series snap action switch family. The following criteria determine substitution eligibility:

Mandatory Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Momentary
• Current rating: 6A AC / 550mA DC
• Voltage rating: 120V AC / 125V DC
• Actuator type: Side Rotary, Adjustable Roller
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Ingress protection: IP67
• Operating temperature range: -25°C to 85°C
• Mechanical life: 15,000,000 Cycles
• RoHS compliance: Required

The GLFB01A2B meets all mandatory parameters and is identified as a direct substitute. The primary distinction is product status: GLFD01A2B is obsolete, while GLFB01A2B is active and currently in production.

Parameter Comparison

Engineering Selection Recommendations

The GLFB01A2B is the direct substitute for the obsolete GLFD01A2B. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the GLS series and share identical electrical, mechanical, and environmental specifications.

Selection Basis:

The GLFB01A2B is currently in active production status with 766 units in stock, whereas the GLFD01A2B is obsolete with limited remaining inventory (1,027 units). For new designs, system upgrades, or long-term supply chain planning, the GLFB01A2B is the appropriate selection.

Both parts maintain identical compliance certifications: RoHS Compliant, MSL Level 1, and ECCN EAR99 classification. No functional, electrical, or mechanical differences exist between these components. The substitution is direct and does not require circuit redesign, mechanical modification, or performance re-evaluation.
