GLDC01A2A Snap Action Switch - Equivalent & Substitute Parts
Part Overview
The GLDC01A2A is a snap action switch manufactured by Honeywell Sensing and Productivity Solutions, classified as a Single Pole Double Throw (SPDT) chassis mount switch. This component is rated for 6A AC at 120V and 550mA DC at 125V, featuring a side rotary adjustable roller actuator with IP67 ingress protection. The GLDC01A2A is currently listed as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs requiring this switch topology.

Engineering Selection Recommendations
The GLDA01A2A is the qualified substitute for the obsolete GLDC01A2A. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the GLS series and maintain identical electrical, mechanical, and environmental specifications.
Selection Basis:
The GLDA01A2A provides functional continuity for applications currently using the GLDC01A2A. The substitute maintains:
- Identical SPDT circuit topology and on-momentary switch function
- Equivalent current and voltage ratings for AC and DC operation
- Matching mechanical interface (chassis mount with screw terminals)
- Identical actuator configuration (side rotary adjustable roller)
- Equivalent environmental protection (IP67 rating)
- Identical operating temperature range and mechanical life cycle rating
- RoHS compliance certification
The primary distinction is product status: GLDA01A2A is currently active in production, whereas GLDC01A2A is obsolete. This substitution ensures continued availability and supply chain continuity for equivalent switch functionality.
Frequently Asked Questions (FAQ)
Q: Can GLDA01A2A directly replace GLDC01A2A in existing applications?
A: Yes. The GLDA01A2A is electrically and mechanically equivalent to the GLDC01A2A across all specified parameters. Both components share identical circuit configuration, current/voltage ratings, actuator type, mounting interface, and termination style. Direct substitution is supported without circuit modification.
Q: What is the difference between GLDC01A2A and GLDA01A2A?
A: The components are functionally identical. The primary difference is product status: GLDC01A2A is obsolete, while GLDA01A2A is active in production. Both are manufactured by Honeywell Sensing and Productivity Solutions within the GLS series.
Q: Are there packaging differences between these parts?
A: The GLDC01A2A is supplied in standard packaging, while GLDA01A2A is supplied in bulk packaging. This distinction does not affect component functionality or electrical/mechanical performance.
Q: Does GLDA01A2A meet the same compliance requirements?
A: Yes. Both GLDC01A2A and GLDA01A2A are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8536.50.7000) classifications.
Q: What are the critical parameters for substitution compatibility?
A: Substitution compatibility is determined by: SPDT circuit configuration, 6A AC current rating, 120V AC voltage rating, 550mA DC at 125V, side rotary adjustable roller actuator, chassis mount interface, screw terminal termination, IP67 ingress protection, -40°C to 85°C operating temperature, and 10,000,000 cycle mechanical life.
