GLCB01K8B Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The GLCB01K8B is a snap action switch manufactured by Honeywell Sensing and Productivity Solutions, classified as SPDT (Single Pole Double Throw) with On-Momentary function. This component is designed for chassis mount applications with screw terminal connections and operates at 6A AC (120V) or 550mA DC (125V).

The GLCB01K8B carries an Obsolete product status. Locating equivalent substitute parts is necessary to maintain system functionality, ensure design continuity, and support ongoing production or maintenance requirements where this component is specified in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GLCB01K8B is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• Current rating must support minimum 6A AC at 120V
• Current rating must support minimum 550mA DC at 125V

Mechanical Compatibility Requirements:

• Actuator type must be Spring with Cat Whisker mechanism
• Mounting type must be Chassis Mount
• Termination style must be Screw Terminal
• Operating force must be 132gf
• Operating position must be 16°
• Pretravel must be 16°
• Differential travel must be 10°

Environmental & Compliance Requirements:

• Ingress protection must be IP66 or equivalent
• Operating temperature range must encompass -25°C to 85°C
• RoHS compliance status must be maintained
• Mechanical life must meet or exceed 5,000,000 cycles

The substitute part GLCA01K8A meets all specified parameters and is therefore electrically and mechanically interchangeable with the GLCB01K8B.

Engineering Selection Recommendations

Primary Recommendation: GLCA01K8A

The GLCA01K8A is the direct equivalent substitute for the obsolete GLCB01K8B. All electrical, mechanical, and environmental parameters are identical. The GLCA01K8A carries Active product status from Honeywell Sensing and Productivity Solutions, ensuring ongoing availability and support.

Compliance Status: Both parts maintain RoHS compliance and carry MSL 1 (Unlimited) moisture sensitivity classification. The GLCA01K8A additionally carries REACH Unaffected status, providing extended regulatory coverage.

Availability Consideration: The GLCA01K8A is currently in stock with 980 pieces available as new original inventory, compared to the GLCB01K8B which is obsolete. For new designs or replacement applications, the GLCA01K8A should be specified.

Packaging Note: The GLCA01K8A is supplied in Bulk packaging, whereas the GLCB01K8B packaging specification was not provided. Confirm packaging requirements for your procurement process.

Frequently Asked Questions (FAQ)

Q: Can GLCA01K8A directly replace GLCB01K8B in existing designs?

A: Yes. The GLCA01K8A is electrically and mechanically identical to the GLCB01K8B across all specified parameters including circuit configuration, current and voltage ratings, actuator type, mounting configuration, and termination style. Direct substitution is supported without design modification.

Q: Why is the GLCB01K8B listed as Obsolete?

A: The GLCB01K8B has reached end-of-life status with Honeywell Sensing and Productivity Solutions. The GLCA01K8A serves as the active replacement part with identical performance specifications.

Q: Are there any differences in mechanical life or operating characteristics?

A: No. Both parts specify 5,000,000 mechanical life cycles, identical operating force of 132gf, and matching operating position, pretravel, and differential travel parameters. Functional performance is equivalent.

Q: What is the difference between the two part numbers?

A: The GLCA01K8A is the active production equivalent. The GLCB01K8B is the obsolete predecessor. Both are manufactured by Honeywell Sensing and Productivity Solutions within the GLS series. The substitution is based on complete parameter equivalence.

Q: Does packaging differ between these parts?

A: The GLCA01K8A is supplied in Bulk packaging. The GLCB01K8B packaging specification was not documented. Confirm your packaging requirements with your supplier when transitioning to the GLCA01K8A.

Q: Are both parts RoHS compliant?

A: Yes. Both the GLCB01K8B and GLCA01K8A are RoHS compliant. The GLCA01K8A additionally carries REACH Unaffected status.

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

A: Both parts operate across -25°C to 85°C. This range is suitable for industrial and commercial applications within standard environmental conditions.

Q: Can these switches be used in DC applications?

A: Yes. Both parts are rated for 550mA DC at 125V, in addition to their 6A AC rating at 120V. Application selection should be based on your specific circuit requirements.
