GLBA02A2A Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The GLBA02A2A is a snap action switch manufactured by Honeywell Sensing and Productivity Solutions, classified as an SPDT (Single Pole Double Throw) chassis mount switch with side rotary adjustable roller actuator. This component is rated for 6A AC at 120V and 550mA DC at 125V, featuring IP67 ingress protection suitable for dust-tight and waterproof applications.

The GLBA02A2A is currently listed as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this switch configuration.

Substitute Part Grouping Explanation

Substitution of the GLBA02A2A is based on electrical and mechanical parameter equivalence within the Honeywell GLS series snap action switch family. The substitute part GLBC02A2B maintains identical specifications across all critical functional parameters:

Substitution Criteria (Matched Parameters):

• Circuit configuration: SPDT
• Switch function: On-Momentary
• Current ratings: 6A AC / 550mA DC
• Voltage ratings: 120V AC / 125V DC
• Actuator type: Side Rotary, Adjustable Roller
• Mounting type: Chassis Mount
• Termination style: Plug In
• Ingress protection: IP67
• Operating temperature range: -25°C to 85°C
• Mechanical life: 15,000,000 Cycles
• RoHS compliance: Compliant

The GLBC02A2B differs from the GLBA02A2A in product status (Active vs. Obsolete), roller material composition (Steel vs. Nylon), and packaging format (Bulk vs. standard). These differences do not affect functional equivalence for electrical and mechanical applications.

Parameter Comparison

Engineering Selection Recommendations

The GLBC02A2B is the direct functional equivalent for the obsolete GLBA02A2A. Selection of the GLBC02A2B is supported by the following engineering factors:

Product Status: The GLBC02A2B maintains Active product status with Honeywell, ensuring ongoing availability, technical support, and supply chain continuity. The GLBA02A2A is classified as Obsolete, creating supply and support limitations.

Compliance and Certification: Both parts maintain identical RoHS compliance status and MSL rating of 1 (Unlimited), confirming equivalent environmental and handling requirements. Both parts carry ECCN classification EAR99, indicating equivalent export control status.

Electrical and Mechanical Equivalence: All functional parameters—circuit configuration, current and voltage ratings, actuator characteristics, mounting specifications, ingress protection rating, operating temperature range, and mechanical life—are identical between the two parts.

Material Consideration: The GLBC02A2B features a steel roller actuator compared to the nylon roller in the GLBA02A2A. Steel roller construction provides enhanced durability and wear resistance in high-cycle applications, representing a material upgrade rather than a functional change.

Frequently Asked Questions (FAQ)

Q: Can GLBC02A2B be used as a direct replacement for GLBA02A2A in existing designs?

A: Yes. The GLBC02A2B is electrically and mechanically equivalent to the GLBA02A2A across all specified parameters. Both parts are SPDT snap action switches with identical current ratings (6A AC / 550mA DC), voltage ratings (120V AC / 125V DC), actuator configuration, mounting type, and ingress protection rating. The parts are functionally interchangeable.

Q: What is the difference between the nylon roller in GLBA02A2A and the steel roller in GLBC02A2B?

A: The roller material differs between the two parts. GLBA02A2A uses a nylon roller, while GLBC02A2B uses a steel roller. Steel provides greater hardness and wear resistance, particularly in applications with frequent actuation cycles or exposure to abrasive conditions. Both materials meet the specified 15,000,000 cycle mechanical life requirement.

Q: Why is GLBA02A2A listed as Obsolete?

A: The GLBA02A2A is classified as Obsolete by Honeywell, indicating that the manufacturer has discontinued active production and support for this part number. The GLBC02A2B represents the current active equivalent within the GLS series product line.

Q: Are there packaging differences between these parts?

A: Yes. The GLBA02A2A is supplied in standard packaging, while the GLBC02A2B is supplied in Bulk packaging. Packaging format does not affect component functionality or electrical performance. Selection between packaging options depends on procurement and inventory management requirements.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both GLBA02A2A and GLBC02A2B are RoHS Compliant and carry MSL rating 1 (Unlimited), confirming equivalent environmental compliance and moisture sensitivity specifications.

Q: What is the operating temperature range for these switches?

A: Both parts operate across the identical temperature range of -25°C to 85°C, ensuring equivalent thermal performance in industrial and commercial applications.

Q: Are the actuator specifications identical between the two parts?

A: Yes. Both parts feature identical side rotary adjustable roller actuators with matching operating force (33gfm), operating position (26°), pretravel (26°), differential travel (12°), and overtravel (59°) specifications.
