CUI Devices 63S1120 Equivalent & Substitute Parts

Part Overview

The CUI Devices 63S1120 is an internally driven electromechanical buzzer rated for 12V DC operation, designed for panel mount applications with flange termination and wire leads. This component operates at 400Hz with a sound pressure level of 75dB at 12V measured 30cm from the device, consuming 25mA during operation. The 63S1120 is classified as obsolete, necessitating identification of active substitute components that maintain functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 63S1120 is based on the following critical parameters that define functional compatibility:

Electrical Compatibility:

• Rated voltage of 12V DC with acceptable operating range overlap
• Internally driven indicator circuitry requiring no external driver
• DC input type

Mechanical Compatibility:

• Panel mount configuration with flange mounting interface
• Wire lead termination for direct circuit connection
• Physical dimensions permitting installation in existing mounting locations

Operational Compatibility:

• Single tone operating mode
• Sound pressure level sufficient for audible indication
• Current consumption within power supply capability

The CUI Devices CS-3612 qualifies as a substitute based on matching electrical input requirements (12V DC, internally driven), identical mounting configuration (panel mount flange), and compatible termination (wire leads). Both components operate within overlapping voltage ranges and maintain the same functional classification as internally driven indicators.

Parameter Comparison

Engineering Selection Recommendations

The CS-3612 is the designated substitute for the obsolete 63S1120 based on the following engineering criteria:

Product Status: The 63S1120 is obsolete and no longer manufactured. The CS-3612 is active and available in production quantities (2898 pcs in stock versus 890 pcs for the obsolete part).

Regulatory Compliance: Both components maintain RoHS compliance. The CS-3612 carries ROHS3 certification, representing current regulatory alignment. Both components are REACH unaffected and classified under identical HTSUS and ECCN codes.

Electrical Compatibility: Both components operate at 12V DC with internally driven indicator circuitry. The CS-3612 voltage range (8 ~ 16V) encompasses the 63S1120 range (9 ~ 15V), providing equivalent or superior voltage tolerance.

Mechanical Compatibility: Identical panel mount flange configuration and wire lead termination ensure direct installation compatibility in existing designs.

Operational Differences: The CS-3612 operates as a magnetic buzzer versus the electromechanical technology of the 63S1120, producing 82dB SPL compared to 75dB SPL. Current consumption increases from 25mA to 35mA. Operating temperature range expands from -10°C ~ 60°C to -30°C ~ 70°C.

Frequently Asked Questions (FAQ)

Q: Can the CS-3612 directly replace the 63S1120 in existing designs?

A: Yes. Both components share identical electrical input requirements (12V DC, internally driven), mounting configuration (panel mount flange), and termination type (wire leads). No circuit modifications are required.

Q: What are the key differences between these components?

A: The primary differences are technology type (electromechanical versus magnetic), sound output (75dB versus 82dB SPL), current consumption (25mA versus 35mA), and operating temperature range (-10°C ~ 60°C versus -30°C ~ 70°C). The CS-3612 provides higher sound output and broader temperature operation.

Q: Does the increased current consumption of the CS-3612 affect circuit design?

A: The CS-3612 requires 35mA compared to the 63S1120's 25mA. Power supply and current-limiting circuits must accommodate this 10mA increase. Verify that existing power supply capacity and circuit protection devices support the higher current draw.

Q: Are there packaging differences between these parts?

A: The 63S1120 is supplied without specified packaging, while the CS-3612 is supplied in trays. This affects inventory management and component handling but does not impact functional performance.

Q: What is the frequency specification for the CS-3612?

A: The CS-3612 frequency specification is not provided in the available technical data. The 63S1120 operates at 400Hz. Frequency compatibility should be confirmed through CUI Devices technical documentation if frequency-specific requirements exist in the application.
