GSAC07A1B Equivalent & Substitute Parts Reference

Part Overview

The GSAC07A1B is a rotary side switch manufactured by Honeywell Sensing and Productivity Solutions, designed for chassis mount applications with screw terminal connections. This switch operates across a temperature range of -25°C to 80°C and delivers 25,000 electrical cycles with 1,000,000 mechanical cycles. The component maintains Active product status and carries RoHS Compliant certification with MSL Level 1 rating.

Substitute parts are identified to provide alternative sourcing options when the primary GSAC07A1B component is unavailable or when design requirements permit equivalent functionality. All substitute components share critical mechanical and environmental specifications including chassis mount configuration, screw terminal termination, IP67 ingress protection rating, and compatible operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for GSAC07A1B are qualified based on the following critical parameters that determine functional equivalence:

Mechanical Compatibility:

• Chassis mount configuration
• Screw terminal termination style
• IP67 ingress protection rating

Environmental Specifications:

• Operating temperature range compatibility
• Moisture sensitivity level (MSL 1)
• RoHS compliance status

Electrical Characteristics:

• Side rotary actuator type
• Roller actuator design
• Snap action switch mechanism

The four substitute parts (D4B-2115N, D4B-2511N, D4B-2515N, D4B-4111N) all originate from Omron Automation and Safety's D4B-N series and satisfy these core substitution criteria. Each substitute maintains IP67 protection, operates within compatible temperature ranges (-40°C to 80°C), features screw terminal connections, and utilizes chassis mount configurations identical to the main part.

Differences in circuit configuration (SPDT versus DPST), current ratings, and cycle life ratings do not preclude substitution when application requirements align with the specific electrical characteristics of each substitute model.

Parameter Comparison

Engineering Selection Recommendations

Product Status Alignment: All substitute parts maintain Active product status, ensuring continued availability and manufacturer support equivalent to the GSAC07A1B.

Compliance Certification: All substitute components carry ROHS3 Compliant certification, meeting or exceeding the RoHS Compliant status of the main part. All parts are classified under ECCN EAR99 with identical HTSUS coding (8536.50.7000), confirming regulatory equivalence for export and procurement purposes.

Moisture Sensitivity: All substitute parts carry MSL Level 1 (Unlimited) rating, matching the main part's moisture sensitivity classification and eliminating special handling requirements during storage and assembly.

Temperature Operating Range: Substitute parts operate across -40°C to 80°C, which encompasses the GSAC07A1B operating range of -25°C to 80°C. This extended lower temperature capability provides additional operational margin in cold environment applications.

Mechanical and Environmental Protection: All substitute parts maintain IP67 ingress protection rating and chassis mount configuration with screw terminal termination, ensuring direct mechanical and electrical compatibility with existing PCB layouts and enclosure designs.

Frequently Asked Questions (FAQ)

Q: Can D4B-2115N directly replace GSAC07A1B in all applications?

A: D4B-2115N shares critical mechanical specifications (chassis mount, screw terminal, IP67 protection) with GSAC07A1B. However, D4B-2115N features SPDT circuit configuration with 10A AC / 6A DC current rating and 500,000 electrical cycles, whereas GSAC07A1B specifications for circuit type and current rating are not provided. Substitution is valid when application electrical requirements align with D4B-2115N specifications.

Q: What is the difference between D4B-2511N and D4B-2515N?

A: Both D4B-2511N and D4B-2515N feature identical DPST-NO/NC circuit configuration, current ratings (10A AC / 6A DC), and mechanical specifications. D4B-2515N includes stainless steel roller feature, while D4B-2511N does not specify this feature. Both parts maintain equivalent electrical life (500,000 cycles) and mechanical life (10,000,000 cycles). Selection between these parts depends on corrosion resistance requirements in the application environment.

Q: Are there packaging differences between GSAC07A1B and substitute parts?

A: All parts are supplied in Bulk packaging. Current inventory levels vary: GSAC07A1B (10,100 pcs), D4B-2115N (1,176 pcs), D4B-2511N (679 pcs), D4B-2515N (711 pcs), D4B-4111N (1,027 pcs). Packaging format remains consistent across all parts.

Q: What are the key mechanical differences in actuator design?

A: GSAC07A1B specifies side rotary actuator type. All substitute parts feature side rotary actuator with roller design. Substitute parts provide documented operating force (960gf), release force (150gf), operating position (21°), pretravel (21°), and overtravel (50°) specifications. These mechanical parameters are not specified for GSAC07A1B.

Q: Do substitute parts require different PCB layout considerations?

A: All substitute parts maintain identical mounting type (chassis mount) and termination style (screw terminal) as GSAC07A1B. No PCB layout modifications are required for mechanical compatibility. Electrical circuit routing may require adjustment based on the specific circuit configuration (SPDT or DPST) selected for substitution.

Q: What is the temperature operating margin for substitute parts?

A: GSAC07A1B operates from -25°C to 80°C. All substitute parts operate from -40°C to 80°C, providing an additional 15°C margin at the lower temperature limit. This extended range accommodates applications requiring operation in colder environments without component derating.

Q: Are all substitute parts RoHS compliant?

A: Yes. GSAC07A1B carries RoHS Compliant certification. All substitute parts carry ROHS3 Compliant certification, which represents an updated compliance standard. Both certifications satisfy RoHS directive requirements for procurement and assembly in regulated markets.
