GLCB36C Equivalent & Substitute Parts Reference

Part Overview

The GLCB36C is a snap-action switch manufactured by Honeywell Sensing and Productivity Solutions, configured as a DPST-NC (Double Pole Single Throw - Normally Closed) chassis-mount device. This switch is rated for 0.1A at 50V AC/DC with a roller plunger actuator and IP67 ingress protection. The product is currently classified as obsolete, making identification of equivalent substitute parts essential for system maintenance, repair, and component sourcing in legacy applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GLCB36C is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit Configuration: DPST-NC (DB)
• Switch Function: On-Momentary
• Current Rating: 100mA (AC/DC)
• Actuator Type: Roller Plunger
• Mounting Type: Chassis Mount
• Termination Style: Screw Terminal
• Ingress Protection: IP67
• Operating Force: 1632gf
• Operating Position: 1.100" (28.0mm)
• Pretravel: 0.120" (3.0mm)
• Differential Travel: 0.035" (0.9mm)
• Overtravel: 0.118" (3.0mm)
• Operating Temperature Range: -40°C to 85°C
• Mechanical Life: 15,000,000 Cycles

Allowable Variation Parameters:

• Voltage Rating: The substitute part may have higher voltage ratings (50V minimum required)
• Product Status: Active status is acceptable for obsolete parts
• Packaging: Variations in packaging format are acceptable

The GLDB36C qualifies as a substitute because it maintains all mandatory parameters while offering enhanced voltage ratings (120V AC / 125V DC) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The GLDB36C is a direct substitute for the GLCB36C based on the following engineering criteria:

Functional Equivalence: Both parts maintain identical circuit configuration (DPST-NC), switch function (On-Momentary), current handling (100mA AC/DC), mechanical characteristics (roller plunger, 1632gf operating force), and environmental specifications (IP67, -40°C to 85°C operating range).

Electrical Compatibility: The GLDB36C provides higher voltage ratings (120V AC / 125V DC) compared to the GLCB36C (50V AC/DC). This represents an upward-compatible specification, meaning the GLDB36C can be used in any application where the GLCB36C was originally specified, provided the circuit design does not depend on the lower voltage rating.

Product Status Advantage: The GLDB36C holds active product status, ensuring continued availability, technical support, and supply chain reliability. The GLCB36C is classified as obsolete, making the GLDB36C the preferred selection for new designs and ongoing maintenance applications.

Compliance Certification: Both parts are RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting modern environmental and reliability standards.

Frequently Asked Questions (FAQ)

Q: Can the GLDB36C directly replace the GLCB36C in existing applications?

A: Yes. The GLDB36C maintains all critical mechanical and electrical parameters of the GLCB36C. The higher voltage rating of the GLDB36C (120V AC / 125V DC versus 50V AC/DC) is compatible with applications originally designed for the GLCB36C, as long as the circuit does not specifically require the lower voltage threshold.

Q: What is the primary difference between GLCB36C and GLDB36C?

A: The primary difference is the voltage rating. The GLCB36C is rated for 50V AC/DC, while the GLDB36C is rated for 120V AC / 125V DC. All other specifications, including circuit configuration, current rating, mechanical characteristics, and environmental protection, are identical.

Q: Why is the GLCB36C listed as obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The GLDB36C, as an active product in the same GLS series with equivalent functionality and higher voltage capability, serves as the recommended replacement for ongoing applications.

Q: Are there any packaging differences between GLCB36C and GLDB36C?

A: The GLCB36C is listed with standard packaging, while the GLDB36C is supplied in bulk packaging. Both parts use identical screw terminal termination and chassis mount configuration. Packaging format does not affect electrical or mechanical compatibility.

Q: What mechanical specifications must remain identical for substitution?

A: The following mechanical specifications must be identical: actuator type (roller plunger), operating force (1632gf), operating position (1.100" / 28.0mm), pretravel (0.120" / 3.0mm), differential travel (0.035" / 0.9mm), and overtravel (0.118" / 3.0mm). The GLDB36C matches all these specifications exactly.

Q: Is the GLDB36C suitable for applications requiring IP67 ingress protection?

A: Yes. The GLDB36C maintains IP67 rating (dust tight, waterproof), identical to the GLCB36C, making it suitable for sealed and environmentally protected applications.

Q: What is the mechanical life expectancy of the GLDB36C?

A: The GLDB36C is rated for 15,000,000 mechanical cycles, matching the GLCB36C specification. This rating applies to the roller plunger actuator mechanism under normal operating conditions within the specified temperature range (-40°C to 85°C).
