GLBA02A Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The GLBA02A is a snap action switch manufactured by Honeywell Sensing and Productivity Solutions, classified as an SPDT (Single Pole Double Throw) chassis mount switch. This component is rated for 6A AC at 120V and 550mA DC at 125V, featuring a side rotary actuator without lever and plug-in termination. The GLBA02A is currently listed as obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and system continuity in applications where this switch was originally specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GLBA02A is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical areas:

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 (Side Rotary - No Lever), mounting configuration (Chassis Mount), termination method (Plug In), and all actuation characteristics (operating force, position, pretravel, differential travel, and overtravel) must be identical.

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

Only parts meeting all these criteria are classified as direct substitutes capable of replacement without circuit modification or application redesign.

Parameter Comparison

Engineering Selection Recommendations

The GLBB02A is a direct functional equivalent to the GLBA02A. All electrical specifications, mechanical characteristics, environmental ratings, and compliance certifications are identical. The primary distinction is product status: the GLBA02A is obsolete while the GLBB02A is active and currently manufactured.

For applications currently using the GLBA02A, the GLBB02A provides continuity of supply and function. Both components are RoHS compliant and carry MSL 1 rating, indicating no moisture sensitivity constraints during storage or handling. The GLBB02A is available in active inventory (1106 pieces), whereas the GLBA02A stock is limited to existing inventory (970 pieces).

No circuit modifications, connector changes, or application redesign are required when transitioning from GLBA02A to GLBB02A. The components are mechanically and electrically interchangeable within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can GLBB02A directly replace GLBA02A without any modifications?

A: Yes. The GLBB02A is electrically and mechanically identical to the GLBA02A across all specified parameters. No circuit modifications, connector changes, or application redesign are necessary. Direct substitution is supported.

Q: What is the primary reason to consider GLBB02A as an alternative?

A: The GLBA02A is classified as obsolete, creating supply continuity risk. The GLBB02A is an active product from the same manufacturer and series, offering ongoing availability and support.

Q: Are the electrical ratings identical between these two parts?

A: Yes. Both components are rated for 6A AC at 120V and 550mA DC at 125V with SPDT circuit configuration and On-Momentary switch function.

Q: Do the mechanical characteristics match?

A: Yes. Operating force (33gfm), actuator type (Side Rotary - No Lever), mounting (Chassis Mount), termination (Plug In), and all actuation parameters (operating position, pretravel, differential travel, overtravel) are identical.

Q: Are environmental and compliance ratings the same?

A: Yes. Both parts maintain IP67 ingress protection, operate across -25°C to 85°C, support 15,000,000 mechanical cycles, are RoHS compliant, and carry MSL 1 rating.

Q: What is the difference between GLBA02A and GLBB02A?

A: The only difference is product status. GLBA02A is obsolete; GLBB02A is active. All technical specifications are identical.

Q: Is inventory availability a consideration?

A: Yes. GLBB02A has 1106 pieces in active stock, while GLBA02A inventory is limited to existing supply (970 pieces). For long-term applications, GLBB02A ensures sustained availability.
