Key Parameters

Substitute Part Grouping Explanation

Substitution of the GLBA02A4J is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom)
• Current rating: 6A AC and 550mA DC
• Voltage rating: 120V AC and 125V DC

Mechanical Compatibility Parameters:

• Actuator type (Side Rotary, Adjustable Rod)
• Mounting type (Chassis Mount)
• Termination style (Plug In)
• Operating force (33gfm)
• Angular specifications: 26° operating position, 26° pretravel, 12° differential travel, 59° overtravel

Environmental & Compliance Parameters:

• Ingress protection (IP67)
• Operating temperature range (-25°C to 85°C)
• Mechanical life (15,000,000 cycles)
• RoHS compliance
• MSL rating (1 - Unlimited)

Only components matching all these parameters across electrical, mechanical, and environmental specifications are considered valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

The GLBC02A4J is a direct functional equivalent to the GLBA02A4J across all electrical, mechanical, and environmental parameters. The primary distinction is product status: GLBA02A4J is obsolete while GLBC02A4J is active.

For applications currently using GLBA02A4J, the GLBC02A4J provides identical performance specifications and is manufactured by the same supplier within the same GLS series. Both components are RoHS compliant and carry MSL 1 rating, indicating no moisture sensitivity constraints during storage and handling.

The GLBC02A4J is the recommended substitute for new procurement and system maintenance where GLBA02A4J components are no longer available. Current inventory of GLBC02A4J (705 pieces) supports immediate component availability.

Frequently Asked Questions (FAQ)

Q: Can GLBC02A4J directly replace GLBA02A4J in existing applications?

A: Yes. The GLBC02A4J is electrically and mechanically identical to GLBA02A4J. All circuit configurations, current and voltage ratings, actuator specifications, mounting requirements, and environmental ratings are equivalent. No circuit redesign or mechanical modification is required.

Q: What is the primary reason for substitution?

A: GLBA02A4J is obsolete. GLBC02A4J is the active equivalent part from Honeywell Sensing and Productivity Solutions, ensuring continued component availability and supply chain continuity.

Q: Are there any compliance or certification differences?

A: No. Both GLBA02A4J and GLBC02A4J are RoHS compliant with identical MSL 1 ratings. Compliance certifications and environmental qualifications are equivalent.

Q: What are the key parameters that define substitution eligibility?

A: Substitution is based on matching: SPDT circuit configuration, On-Mom switch function, 6A AC / 550mA DC current ratings, 120V AC / 125V DC voltage ratings, side rotary adjustable rod actuator, chassis mount configuration, plug-in termination, IP67 ingress protection, 33gfm operating force, 26° operating position, 26° pretravel, 12° differential travel, 59° overtravel, -25°C to 85°C operating temperature, and 15,000,000 cycle mechanical life.

Q: Is inventory availability a factor in component selection?

A: GLBC02A4J has 705 pieces in current stock, supporting immediate procurement. GLBA02A4J inventory (828 pieces) is limited to existing stock only, as the part is obsolete.

Q: Are there any packaging or termination differences?

A: No. Both components use identical plug-in termination style and chassis mount configuration. Packaging specifications are equivalent.
