GLDC07B Equivalent & Substitute Parts Reference

Part Overview

The GLDC07B is a snap action switch manufactured by Honeywell Sensing and Productivity Solutions, configured as a single-pole double-throw (SPDT) device with momentary on-function operation. This chassis-mounted switch is rated for 100mA at 50V AC/DC with IP67 ingress protection, suitable for applications requiring sealed, dust-tight and waterproof switching functionality.

The GLDC07B carries an obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GLDC07B is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom (momentary operation)
• Current rating: 100mA AC/DC
• Voltage rating: 50V AC and 50V DC
• Actuator type: Round pin plunger
• Mounting type: Chassis mount
• Termination style: Screw terminal
• Ingress protection: IP67
• Mechanical life: 15,000,000 cycles minimum
• RoHS compliance status

The GLAC07B meets all mandatory matching parameters and qualifies as a direct substitute. Both parts share identical electrical ratings, mechanical durability specifications, environmental sealing characteristics, and regulatory compliance certifications. Differences in operating position, pretravel, differential travel, overtravel, and operating temperature range do not preclude substitution when these mechanical variations are acceptable within the application's design constraints.

Parameter Comparison

Engineering Selection Recommendations

The GLAC07B is the qualified substitute for the obsolete GLDC07B. Selection of GLAC07B is supported by the following engineering factors:

Product Status: GLAC07B maintains active product status with Honeywell, ensuring ongoing availability, technical support, and supply chain continuity. The GLDC07B is obsolete, making GLAC07B the appropriate forward-looking alternative.

Electrical and Mechanical Equivalence: Both parts share identical electrical ratings (100mA, 50V AC/DC), circuit configuration (SPDT), switch function (On-Mom), and mechanical durability (15,000,000 cycles). Operating force is identical at 1632gf.

Environmental and Regulatory Compliance: Both parts meet IP67 ingress protection requirements, RoHS compliance, and identical export control classifications (EAR99). Moisture sensitivity level is equivalent (MSL 1 - Unlimited).

Mechanical Differences: GLAC07B exhibits a longer operating position (35.0mm versus 18.0mm), slightly reduced pretravel (2.5mm versus 3.0mm), and increased overtravel (4.6mm versus 3.0mm). The operating temperature range for GLAC07B is -25°C to 85°C, compared to -40°C to 85°C for GLDC07B. These differences require evaluation within the specific application context to confirm compatibility with mechanical envelope constraints and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can GLAC07B directly replace GLDC07B in all applications?

A: GLAC07B qualifies as an electrical and mechanical substitute based on matching circuit configuration, current/voltage ratings, actuator type, mounting method, termination style, ingress protection, and mechanical life specifications. However, the differences in operating position (35.0mm versus 18.0mm) and operating temperature minimum (-25°C versus -40°C) must be evaluated against specific application requirements. Applications operating below -25°C or with mechanical envelope constraints related to the 18.0mm operating position require detailed compatibility assessment.

Q: What are the key differences between GLDC07B and GLAC07B?

A: The primary differences are: (1) Product status—GLAC07B is active while GLDC07B is obsolete; (2) Operating position—GLAC07B operates at 35.0mm versus GLDC07B at 18.0mm; (3) Pretravel—GLAC07B at 2.5mm versus GLDC07B at 3.0mm; (4) Overtravel—GLAC07B at 4.6mm versus GLDC07B at 3.0mm; (5) Operating temperature minimum—GLAC07B at -25°C versus GLDC07B at -40°C. All other electrical, mechanical, and compliance parameters are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both GLDC07B and GLAC07B are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8536.50.7000) classifications.

Q: What is the mechanical life expectancy for both parts?

A: Both GLDC07B and GLAC07B are rated for 15,000,000 mechanical cycles, providing equivalent durability and service life.

Q: Does the difference in operating position affect substitution?

A: Operating position difference (35.0mm for GLAC07B versus 18.0mm for GLDC07B) affects the physical travel distance required to actuate the switch. This difference must be evaluated against mechanical envelope constraints, actuator linkage design, and application-specific spatial limitations. If the application accommodates the longer operating position, substitution is feasible from an electrical standpoint.

Q: What is the operating temperature range for each part?

A: GLDC07B operates from -40°C to 85°C. GLAC07B operates from -25°C to 85°C. Applications requiring operation below -25°C must retain GLDC07B or identify alternative solutions, as GLAC07B does not meet the lower temperature requirement.

Q: Are the screw terminal connections identical?

A: Yes. Both parts use screw terminal termination style, ensuring compatible wiring and connection methods.
