Key Parameters

Substitute Part Grouping Explanation

Substitution of the GLAB01K8B is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters: Circuit configuration (SPDT), switch function (On-Momentary), current ratings (6A AC / 550mA DC), and voltage ratings (120V AC / 125V DC) must be exactly matched.

Mechanical Parameters: Actuator type (Spring, Cat Whisker), mounting configuration (Chassis Mount), and termination style (Screw Terminal) must be identical.

Environmental & Durability: Ingress protection rating (IP67), operating temperature range (-25°C to 85°C), and mechanical life (15,000,000 cycles) must be preserved.

Compliance: RoHS compliance status must be maintained.

The GLAA01K8B qualifies as a direct substitute based on complete parameter alignment across all specified categories.

Frequently Asked Questions (FAQ)

Q: Can the GLAA01K8B directly replace the GLAB01K8B in existing applications?

A: Yes. The GLAA01K8B is a direct equivalent substitute. All electrical parameters (6A AC at 120V, 550mA DC at 125V), mechanical specifications (SPDT, On-Momentary, Spring Cat Whisker actuator), mounting configuration (Chassis Mount with Screw Terminal), and environmental ratings (IP67, -25°C to 85°C) are identical.

Q: What is the primary reason for substitution?

A: The GLAB01K8B is classified as obsolete. The GLAA01K8B provides an active, currently manufactured alternative with identical specifications, ensuring long-term supply chain continuity.

Q: Are there packaging differences between these parts?

A: The GLAB01K8B packaging specification is listed as "-" (not specified), while the GLAA01K8B is supplied in bulk packaging. Packaging format does not affect electrical or mechanical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the GLAB01K8B and GLAA01K8B are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8536.50.9055) classifications.

Q: What mechanical life expectancy should be anticipated?

A: Both parts are rated for 15,000,000 mechanical cycles, providing equivalent durability and operational lifespan.

Q: Is the actuator mechanism identical?

A: Yes. Both parts utilize a Spring and Cat Whisker actuator type with identical operating characteristics (18° operating position, 18° pretravel, 8° differential travel, 10gfm operating force).
