GLDA03A1B Equivalent & Substitute Parts Reference

Part Overview

The GLDA03A1B is a snap action switch manufactured by Honeywell Sensing and Productivity Solutions, configured as a single-pole double-throw (SPDT) device with momentary-on function. This component is rated for 6A AC at 120V and 550mA DC at 125V, featuring a side rotary roller actuator with chassis mount configuration and screw terminal termination. The part is classified as obsolete, necessitating identification of active equivalent components to maintain supply chain continuity for applications requiring identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete GLDA03A1B is based on strict equivalence across all critical electrical and mechanical parameters. The substitute component must maintain identical specifications in the following categories:

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

Mechanical Parameters: Actuator type (side rotary roller), mounting configuration (chassis mount), termination method (screw terminal), and ingress protection rating (IP67).

Environmental & Compliance Parameters: Operating temperature range (-40°C to 85°C), mechanical life (10,000,000 cycles), RoHS compliance, and MSL rating (1).

The GLCB03A1B meets all substitution criteria as an active product within the same GLS series, offering identical functional and physical characteristics with the distinction of active product status and bulk packaging availability.

Parameter Comparison

Engineering Selection Recommendations

The GLCB03A1B is the direct equivalent substitute for the obsolete GLDA03A1B. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the GLS series and maintain identical electrical specifications, mechanical configurations, and environmental ratings.

The primary distinction is product status: GLDA03A1B is obsolete while GLCB03A1B is active. For new designs, procurement of replacement inventory, or long-term supply chain planning, GLCB03A1B is the appropriate selection. Both parts are RoHS compliant and carry MSL rating 1, indicating no moisture sensitivity restrictions.

Packaging differs between the two parts (standard versus bulk), which may influence procurement decisions based on volume requirements and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Can GLCB03A1B be used as a direct replacement for GLDA03A1B in existing applications?

A: Yes. The GLCB03A1B is electrically and mechanically identical to GLDA03A1B. All circuit configurations, current and voltage ratings, actuator specifications, mounting methods, and environmental operating parameters are equivalent. Direct substitution is appropriate for both repair and new procurement scenarios.

Q: What is the difference between GLDA03A1B and GLCB03A1B?

A: The components are functionally identical. The primary differences are product status (GLDA03A1B is obsolete; GLCB03A1B is active) and packaging format (standard versus bulk). GLCB03A1B offers greater inventory availability and ongoing manufacturer support.

Q: Are there any compatibility concerns with the screw terminal configuration?

A: No. Both parts use identical screw terminal termination. Existing wiring harnesses and connection methods designed for GLDA03A1B are fully compatible with GLCB03A1B without modification.

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

A: Yes. Both GLDA03A1B and GLCB03A1B are RoHS compliant, rated for -40°C to 85°C operation, feature IP67 ingress protection, and carry MSL rating 1 (unlimited moisture sensitivity level). Mechanical life specification is 10,000,000 cycles for both components.

Q: Which part should be selected for new designs?

A: GLCB03A1B should be selected for new designs. As an active product with established supply chain availability, it provides design continuity and long-term component availability. The obsolete status of GLDA03A1B makes it unsuitable for new development.

Q: Is bulk packaging a requirement for substitution?

A: No. Bulk packaging is a procurement option, not a functional requirement. The electrical and mechanical specifications are identical regardless of packaging format. Packaging selection depends on inventory management and volume requirements specific to your application.
