Key Parameters

Substitute Part Grouping Explanation

Substitution of the Crouzet 83852501 is evaluated based on the following critical parameters:

Electrical Compatibility Parameters:

• Current rating capacity (minimum 6A AC requirement)
• Voltage rating (minimum 250V AC requirement)
• Circuit configuration (DPST-NO/NC preferred; SPDT acceptable with functional analysis)
• Switch function (On-Mom, Off-Mom operation)

Mechanical Compatibility Parameters:

• Actuator type (Roller Plunger)
• Mounting configuration (Chassis Mount)
• Termination method (Screw Terminal)
• Ingress protection level (IP66 minimum)
• Mechanical life rating (15,000,000 cycles minimum)

Regulatory & Environmental Parameters:

• RoHS compliance status
• Operating temperature range (-25°C to 80°C minimum)
• MSL rating (1 - Unlimited)

The Honeywell GLDA01C is identified as a substitute based on shared mechanical architecture (roller plunger, chassis mount, screw terminal), equivalent mechanical life (15,000,000 cycles), superior ingress protection (IP67), and RoHS compliance. Circuit configuration differs (SPDT vs. DPST-NO/NC), requiring application-level verification of switching logic compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Honeywell GLDA01C serves as an active substitute for the obsolete Crouzet 83852501 based on the following engineering criteria:

Mechanical Compatibility: Both switches employ identical actuator technology (roller plunger), mounting methodology (chassis mount), and termination approach (screw terminal). Mechanical life ratings are equivalent at 15,000,000 cycles, ensuring comparable operational durability.

Electrical Performance: The GLDA01C maintains the 6A AC current rating required by the original specification. DC current capacity is reduced (550mA vs. 3A), which may limit substitution in DC-dominant applications. AC voltage rating is lower (120V vs. 250V), requiring circuit voltage verification before deployment.

Environmental Robustness: The GLDA01C provides enhanced ingress protection (IP67 vs. IP66) and extended operating temperature range (-40°C to 85°C vs. -25°C to 80°C), offering improved environmental performance.

Regulatory Status: Both components maintain RoHS compliance and equivalent MSL ratings, satisfying regulatory requirements for equivalent deployment.

Circuit Configuration Consideration: The primary technical difference is circuit topology (SPDT vs. DPST-NO/NC). Application-level analysis of switching logic requirements is necessary to confirm functional equivalence in the target circuit.

Frequently Asked Questions (FAQ)

Q: Can the Honeywell GLDA01C directly replace the Crouzet 83852501 in all applications?

A: Direct substitution requires verification of three factors: (1) AC voltage requirement must not exceed 120V; (2) DC current requirement must not exceed 550mA; (3) circuit logic must accommodate SPDT switching topology. If all three conditions are met, mechanical and environmental compatibility is established.

Q: What is the primary limitation of the GLDA01C as a substitute?

A: The reduced DC current rating (550mA vs. 3A) and lower AC voltage rating (120V vs. 250V) are the primary electrical constraints. Applications requiring 250V AC operation or 3A DC operation cannot use this substitute without circuit redesign.

Q: Are the mechanical interfaces identical between these switches?

A: Yes. Both switches feature roller plunger actuators, chassis mount configurations, and screw terminal connections. Physical mounting and connection points are compatible. Operating force differs (1632gf vs. 1020gf), which may affect actuator response characteristics in force-sensitive applications.

Q: Does the GLDA01C offer any advantages over the original part?

A: The GLDA01C provides superior ingress protection (IP67 vs. IP66), extended operating temperature range (-40°C to 85°C vs. -25°C to 80°C), and active product status with ongoing manufacturer support. These factors enhance long-term availability and environmental performance.

Q: What packaging considerations apply to the GLDA01C?

A: The GLDA01C is supplied in bulk packaging, whereas the original part number does not specify packaging format. Procurement quantities and packaging requirements should be confirmed with the supplier before order placement.
