GLDA07C Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The GLDA07C is a snap action switch manufactured by Honeywell Sensing and Productivity Solutions, classified as an SPDT (Single Pole Double Throw) chassis mount switch with a roller plunger actuator. This component is rated for 100mA at 50V AC/DC operation and features IP67 ingress protection suitable for dust-tight and waterproof applications.

The GLDA07C is currently listed as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Parameter Comparison

Engineering Selection Recommendations

The GLAB07C is a direct functional substitute for the GLDA07C based on electrical and mechanical parameter equivalence. Both components share identical circuit configuration, current and voltage ratings, actuator type, mounting methodology, and termination style.

For New Designs: The GLAB07C is the recommended selection due to its active product status, ensuring long-term availability and supply chain continuity. This component maintains full compliance with RoHS requirements and carries an unlimited MSL rating.

For Legacy System Support: The GLAB07C provides functional equivalence for systems currently utilizing the GLDA07C. The mechanical parameter variations (operating position, pretravel, and overtravel) fall within acceptable tolerances for chassis-mounted snap action switch applications. The GLAB07C's operating temperature range of -25°C to 85°C covers the majority of industrial and commercial applications; systems requiring operation below -25°C should be evaluated for temperature-specific requirements.

Compliance Considerations: Both components are RoHS compliant and carry identical MSL ratings, eliminating compliance-related substitution barriers. No additional qualification or testing is required from a regulatory standpoint.

Frequently Asked Questions (FAQ)

Q: Can the GLAB07C be used as a direct replacement for the GLDA07C in existing assemblies?

A: Yes. The GLAB07C meets all mandatory electrical and mechanical specifications for the GLDA07C. Both components feature identical SPDT circuit configuration, 100mA current rating at 50V, roller plunger actuation, chassis mount configuration, and screw terminal termination. Mechanical parameter variations are within acceptable tolerances for snap action switch applications.

Q: What are the key differences between GLDA07C and GLAB07C?

A: The primary differences are product status and mechanical positioning parameters. The GLDA07C is obsolete; the GLAB07C is active. Operating position differs (28.0mm versus 48.0mm), pretravel varies (3.0mm versus 2.5mm), and overtravel differs (3.0mm versus 4.6mm). Operating temperature range for GLAB07C is -25°C to 85°C compared to -40°C to 85°C for GLDA07C.

Q: Are there any compliance or certification differences between these parts?

A: No. Both components are RoHS compliant and carry identical MSL ratings of 1 (Unlimited). No additional certifications or compliance barriers exist between the two parts.

Q: Which part should be selected for new product designs?

A: The GLAB07C should be selected for new designs. As an active product from Honeywell Sensing and Productivity Solutions, it ensures supply chain availability and long-term support. The GLDA07C is obsolete and should not be specified for new applications.

Q: Does the operating temperature range difference affect substitution suitability?

A: The GLAB07C's operating temperature range of -25°C to 85°C is suitable for most industrial and commercial applications. Applications requiring operation below -25°C should be evaluated separately. For systems currently operating within the -25°C to 85°C range, the GLAB07C provides full functional equivalence.

Q: Are the mechanical positioning differences significant for chassis mount applications?

A: The mechanical parameter variations between GLDA07C and GLAB07C (operating position, pretravel, and overtravel) are design variations within the GLS series. For chassis mount snap action switch applications, these variations are accommodated within standard mechanical tolerances and do not affect functional substitution suitability.
