Parameter Comparison

Engineering Selection Recommendations

The GLAA20K8C is the direct functional equivalent of the GLAC20K8B. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the GLS series and maintain identical electrical, mechanical, and environmental specifications.

Selection Basis:

The GLAA20K8C is classified as an active product, whereas the GLAC20K8B is obsolete. For new designs, system upgrades, or component replacement requiring long-term availability and manufacturer support, the GLAA20K8C is the appropriate selection.

Both parts are RoHS compliant and carry MSL 1 rating, indicating no moisture sensitivity restrictions during storage and handling. Both are rated for identical electrical loads (6A AC at 120V, 550mA DC at 125V) and mechanical performance (15,000,000 cycle life, 10gfm operating force).

The GLAA20K8C is supplied in bulk packaging, whereas the GLAC20K8B was supplied with standard packaging. This difference does not affect functional or electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can GLAA20K8C be used as a direct replacement for GLAC20K8B in existing applications?

A: Yes. The GLAA20K8C maintains identical electrical ratings, mechanical specifications, actuator characteristics, mounting configuration, and environmental performance as the GLAC20K8B. All critical parameters for circuit operation and physical installation are equivalent.

Q: What is the primary reason to transition from GLAC20K8B to GLAA20K8C?

A: The GLAC20K8B is classified as obsolete. The GLAA20K8C is an active product with ongoing manufacturer support, ensuring availability for future procurement and technical support.

Q: Are there any differences in electrical performance between these two parts?

A: No. Both parts are rated for 6A AC at 120V and 550mA DC at 125V. Both feature DPDT circuit configuration with On-Momentary switch function. Electrical performance is identical.

Q: Do these switches have the same mechanical life expectancy?

A: Yes. Both the GLAC20K8B and GLAA20K8C are rated for 15,000,000 mechanical cycles with identical operating force (10gfm) and actuator travel specifications.

Q: Are there packaging differences between GLAC20K8B and GLAA20K8C?

A: The GLAA20K8C is supplied in bulk packaging, while the GLAC20K8B was supplied with standard packaging. This difference affects only procurement and handling procedures, not component functionality or compatibility.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both parts are RoHS compliant, carry MSL 1 rating (unlimited moisture sensitivity), and are rated for operation across -25°C to 85°C. Both provide IP67 ingress protection (dust tight, waterproof).

Q: Can GLAA20K8C be used in applications originally designed for GLAC20K8B without circuit modifications?

A: Yes. The GLAA20K8C is a functional equivalent with identical electrical and mechanical specifications. No circuit modifications are required for direct substitution.
