GLLA01D Snap Action Switch Equivalent & Substitute Parts

Part Overview

The GLLA01D is a snap action switch manufactured by Honeywell Sensing and Productivity Solutions. This SPDT (Single Pole Double Throw) switch is rated for 10A at 300V AC and 250V DC, featuring a lever/roller actuator with chassis mount configuration and screw terminal termination. The device is IP66 rated for dust-tight and water-resistant operation across an operating temperature range of -10°C to 80°C with 5,000,000 mechanical life cycles. The GLLA01D maintains Active product status with RoHS compliance and MSL Level 1 rating.

Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, enabling component interchangeability in specific circuit configurations and environmental conditions.

Substitute Part Grouping Explanation

Substitute parts for the GLLA01D are identified from the Omron D4N series based on the following substitution criteria:

Mechanical Compatibility Parameters:

• Actuator type: Lever with roller configuration
• Mounting type: Chassis mount
• Termination style: Screw terminal
• Operating force and release force within acceptable range for similar applications

Electrical Compatibility Parameters:

• Voltage rating: 240V AC / 250V DC (within or equal to GLLA01D ratings for DC; lower AC rating requires application verification)
• Current rating: 3A AC / 270mA DC (lower than GLLA01D; suitable for lower-current applications)
• Circuit configuration: DPST-NO/NC (functionally different from SPDT; substitution valid only where dual-pole operation is acceptable)

Environmental & Compliance Parameters:

• Ingress protection: IP67 (exceeds GLLA01D IP66 requirement)
• Operating temperature: -30°C to 70°C (overlaps GLLA01D range; lower upper limit requires application verification)
• Mechanical life: 15,000,000 cycles (exceeds GLLA01D specification)
• RoHS compliance: ROHS3 or equivalent
• MSL rating: 1 (Unlimited)

The D4N series substitutes (D4N-1162, D4N-2A62, D4N-4162, D4N-4A62) are functionally equivalent for applications requiring lower current ratings and dual-pole switching capability.

Parameter Comparison

Engineering Selection Recommendations

GLLA01D Primary Application: The GLLA01D is suitable for applications requiring single-pole double-throw switching at 10A current capacity with 300V AC rating. The device maintains Active product status with full RoHS compliance and unlimited moisture sensitivity level, supporting long-term component availability and regulatory compliance in industrial control systems.

D4N Series Substitution Criteria:

All D4N series substitutes (D4N-1162, D4N-2A62, D4N-4162, D4N-4A62) are suitable for applications where:

• Current requirements do not exceed 3A AC or 270mA DC
• Dual-pole switching (DPST-NO/NC) functionality is acceptable or required
• Operating temperature range of -30°C to 70°C is compatible with application requirements
• Enhanced ingress protection (IP67) is beneficial or required

Compliance Considerations:

• D4N-1162, D4N-4162, and D4N-4A62 carry ROHS3 compliance certification
• D4N-2A62 lists RoHS status as not applicable; verify compliance requirements for specific applications
• All D4N variants maintain MSL Level 1 rating consistent with GLLA01D

Frequently Asked Questions (FAQ)

Q: Can D4N series switches directly replace GLLA01D in all applications?

A: No. D4N substitutes are suitable only for applications where current requirements do not exceed 3A AC or 270mA DC. The GLLA01D supports 10A current capacity; D4N switches cannot be used in higher-current circuits. Additionally, D4N switches provide DPST-NO/NC (dual-pole) functionality rather than SPDT (single-pole) configuration; circuit design must accommodate this difference.

Q: What is the impact of the lower AC voltage rating on D4N switches?

A: D4N switches are rated for 240V AC compared to GLLA01D's 300V AC rating. For applications operating at 240V AC or below, D4N switches are suitable. Applications requiring 300V AC operation must use GLLA01D or equivalent 300V-rated components.

Q: Are there temperature range limitations when substituting D4N for GLLA01D?

A: Yes. D4N switches operate from -30°C to 70°C, while GLLA01D operates from -10°C to 80°C. Applications requiring operation above 70°C must use GLLA01D. Applications within the -30°C to 70°C range can use D4N switches.

Q: What are the mechanical life differences between GLLA01D and D4N switches?

A: GLLA01D provides 5,000,000 mechanical life cycles. D4N switches provide 15,000,000 mechanical life cycles, exceeding GLLA01D specification. For applications with extended cycle requirements, D4N switches offer enhanced durability.

Q: How do operating force and release force differ between GLLA01D and D4N switches?

A: GLLA01D requires 816gf operating force and 153gf release force. D4N switches require 510gf operating force and 82gf release force. Applications with specific actuator force requirements must verify compatibility with the lower force specifications of D4N switches.

Q: Are all D4N variants electrically identical?

A: D4N-1162, D4N-2A62, D4N-4162, and D4N-4A62 share identical electrical ratings (3A AC, 270mA DC, 240V AC, 250V DC). Differences exist in RoHS compliance status and differential travel specification. D4N-2A62 and D4N-4A62 do not specify differential travel values. Verify compliance documentation for specific regulatory requirements.

Q: What is the significance of IP67 rating on D4N switches compared to IP66 on GLLA01D?

A: IP67 (dust-tight, waterproof) provides enhanced protection compared to IP66 (dust-tight, water-resistant). D4N switches can be used in applications requiring GLLA01D's IP66 rating; the higher IP67 rating is compatible with IP66 requirements. Applications requiring only IP66 protection can use either component.

Q: Can GLLA01D be substituted for D4N switches in existing designs?

A: GLLA01D cannot substitute for D4N switches in applications designed for DPST-NO/NC dual-pole functionality. GLLA01D provides SPDT single-pole configuration. Additionally, GLLA01D's higher operating force (816gf vs. 510gf) may not be compatible with actuator mechanisms designed for D4N switches.
