A11CSQ12VDC1.5D

Relay Automotive Overview

The A11CSQ12VDC1.5D is a socketable automotive relay manufactured by CIT Relay and Switch, designed for high-current switching applications in vehicle electrical systems. It features a single-pole double-throw (SPDT) contact configuration with a 12VDC non-latching coil. The unit supports a maximum switching current of 30A at up to 75VDC, utilizing silver tin oxide contacts for durability. Key electrical parameters include a coil resistance of approximately 90 Ohms and a coil power consumption of 1.5W. The device operates within a temperature range of -40°C to 125°C and is sealed against environmental factors.

Relay Automotive Feature Summary

• SPDT contact arrangement provides versatile circuit control capabilities
• Sealed construction ensures protection against moisture and contaminants
• Socketable design facilitates easy installation and replacement
• High switching capacity suitable for demanding automotive loads

Relay Automotive Applications

• Automotive lighting circuits
• Vehicle accessory power distribution
• Industrial control panels requiring SPDT switching
• General purpose low-voltage DC circuit isolation

Relay Automotive Procurement Notes

Verify the specific suffix 'D' corresponds to the desired terminal style and mounting configuration as defined by the manufacturer's catalog. Confirm that the required coil voltage matches the system supply exactly to ensure proper actuation. Check for RoHS compliance status if environmental regulations apply to the end product assembly. Ensure the receiving socket is compatible with the quick-connect pin dimensions specified in the official datasheet.

Relay Automotive Selection Notes

Select this model when a normally open and normally closed contact path is required from a single coil activation. The 30A rating suits moderate load applications such as lamps or small motors. Consider the physical dimensions and base-mounting requirements against available panel space. Evaluate the coil current draw against the controlling source capacity to prevent overload during activation.

Relay Automotive Part Context

This component belongs to the A1 series of automotive relays from CIT Relay and Switch. The series is characterized by robust sealing and standardized pin configurations for reliable performance in harsh environments. The A11CSQ12VDC1.5D specifically denotes the SPDT variant with a 12VDC coil and 1.5W power rating, distinguishing it from SPST or higher-power heavy-duty models within the same family.

Relay Automotive Replacement Considerations

Cross-reference part numbers such as 2449-A11CSQ12VDC1.5R for potential equivalents with similar SPDT characteristics. Verify that any substitute maintains the same coil voltage, contact form, and current rating. Ensure mechanical footprint compatibility if direct board or panel replacement is intended without redesigning the housing.
