GSAC06A1B Equivalent & Substitute Parts Reference

Part Overview

The GSAC06A1B is a DPST-NC (Double Pole Single Throw - Normally Closed) snap-action switch manufactured by Honeywell Sensing and Productivity Solutions. This chassis-mounted switch is rated for 6A AC at 120V and 2.8A DC at 24V, featuring a side rotary roller actuator with IP67 ingress protection. The product is currently obsolete, necessitating identification of functionally equivalent alternatives from active manufacturers to maintain system continuity and support ongoing maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GSAC06A1B is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be DPST-NC
• Switch function must be On-Momentary
• Actuator type must be Side Rotary with Roller
• Mounting type must be Chassis Mount
• Termination style must be Screw Terminal
• Ingress protection must be IP67 or equivalent
• AC voltage rating must support 120V minimum
• DC voltage rating must support 24V minimum

Acceptable Variance Parameters:

• Current ratings may exceed the original specification (higher current capacity is acceptable for direct substitution)
• Operating temperature range may differ if it encompasses the original range
• Mechanical and electrical life specifications may vary

The substitute parts D4B-2A11N and D4B-2A15N, both manufactured by Omron Automation and Safety, meet all primary compatibility criteria. Both are DPST-NC snap-action switches with side rotary roller actuators, chassis mount configuration, screw terminals, and IP67 ingress protection. Both support 120V AC and 30V DC operation, exceeding the original voltage requirements. Current ratings of 10A AC and 6A DC exceed the GSAC06A1B specifications, providing enhanced capacity for the same application envelope.

Parameter Comparison

Engineering Selection Recommendations

Both D4B-2A11N and D4B-2A15N are functionally equivalent substitutes for the obsolete GSAC06A1B based on electrical and mechanical parameter alignment.

D4B-2A11N Selection Criteria:

• Active product status with current manufacturing support
• ROHS3 compliant, meeting current environmental standards
• Standard roller actuator configuration
• Suitable for applications where REACH compliance is not a requirement

D4B-2A15N Selection Criteria:

• Active product status with current manufacturing support
• ROHS3 compliant, meeting current environmental standards
• Stainless steel roller actuator provides enhanced corrosion resistance
• REACH Affected designation indicates compliance with chemical substance regulations
• Recommended for applications requiring extended environmental durability or chemical exposure resistance

Both substitutes provide superior electrical life (500,000 cycles) and mechanical life (10,000,000 cycles) specifications compared to the original part. The higher current ratings (10A AC, 6A DC) ensure compatibility with existing circuit designs while providing operational margin. Operating temperature range of -40°C to 80°C encompasses the majority of the original specification, with a 5°C reduction at the upper limit.

Frequently Asked Questions (FAQ)

Q: Can D4B-2A11N and D4B-2A15N be used interchangeably with GSAC06A1B?

A: Yes. Both Omron parts meet all primary compatibility criteria: DPST-NC circuit configuration, On-Momentary function, side rotary roller actuator, chassis mount, screw terminals, and IP67 ingress protection. Electrical ratings exceed the original specification, ensuring direct functional substitution.

Q: What is the difference between D4B-2A11N and D4B-2A15N?

A: The primary difference is the actuator material. D4B-2A15N features a stainless steel roller, while D4B-2A11N uses a standard roller. D4B-2A15N carries REACH Affected status, indicating compliance with chemical substance regulations. Both parts are electrically and mechanically identical in all other parameters.

Q: Are the voltage and current ratings compatible with the original application?

A: Yes. The substitute parts are rated for 120V AC and 30V DC, exceeding the original 120V AC and 24V DC requirements. Current ratings of 10A AC and 6A DC exceed the original 6A AC and 2.8A DC specifications, providing enhanced capacity without circuit modification.

Q: What is the impact of the 5°C reduction in maximum operating temperature?

A: The substitute parts operate to 80°C maximum, compared to the original 85°C. This 5°C difference is within typical industrial operating margins. Applications requiring operation above 80°C require engineering evaluation against specific system requirements.

Q: Are mechanical and electrical life specifications important for substitution?

A: The substitute parts provide documented electrical life (500,000 cycles) and mechanical life (10,000,000 cycles), whereas the original part specifications do not include these values. These specifications indicate enhanced reliability and predictable maintenance intervals for system planning.

Q: What packaging considerations apply to these substitutes?

A: D4B-2A11N and D4B-2A15N are supplied in Bulk packaging. Verify packaging requirements against procurement specifications. Both parts maintain identical form factor and mounting interface with the original GSAC06A1B.

Q: Are there compliance differences between the substitute parts?

A: Both substitutes are ROHS3 compliant. D4B-2A15N carries REACH Affected status, requiring compliance verification for applications subject to REACH regulations. D4B-2A11N is REACH Unaffected. Select based on regulatory requirements for the end application.
