Other Companies EOL Piezo Buzzer Cross Reference Table (July Updated Version)

For those having trouble with Murata Manufacturing's piezo buzzer, sounder, and piezo elements EOL.

At Same Sky, we continuously manufacture and sell magnetic buzzers and piezo buzzers. Among these, we have received numerous inquiries regarding the EOL (end-of-life) piezo buzzers produced by Murata Manufacturing, so we have listed our products that are believed to be as close as possible.

• Sound Parts

The Same Sky three-wire piezo element utilizes a feedback terminal, allowing it to sound at a single frequency with a simple circuit.

The Same Sky piezo element comes in 2-wire and 3-wire models, with the 3-wire type utilizing a feedback terminal, allowing it to operate at a single frequency with a simple circuit. We have added a feedback-type piezo element that can achieve efficient high sound pressure at the resonant frequency, with a minimum size of Φ12mm x 0.13mm and a resonant frequency range of 2kHz to 4.9kHz.

Expansion of buzzer product lineup / CMI, CMT, CPT series

Same Sky offers buzzers (indicators) with built-in drive circuits and non-built-in buzzers (transducers), each featuring new products that excel in cost performance. The indicators include pin types of Φ9 x 5.5mm, Φ12 x 7.5mm, and Φ12 x 9.5mm, while the transducers include SMT types ranging from 5 x 5 x 2mm to 12 x 12 x 3mm.

• Sound Parts

Piezoelectric element (diaphragm) capable of achieving sound generation functionality with a minimum volume, with diameters ranging from φ15 mm to φ44 mm.

A new product with a diameter of φ12mm, the smallest to date, has been added to our lineup of piezo elements that are easy to incorporate into various products with a thickness of less than 1mm. In addition to this, we also offer sizes φ15mm, φ20mm, φ27mm, and φ35mm, each available with or without lead wires, allowing you to add sound functionality to your application in minimal space.

A new series of buzzers with LED has been launched. These are panel-mounted buzzers with pins available in red, blue, yellow, and green.

The lineup of CUI's buzzers has introduced the 4 series with LED options. Each series offers red, blue, yellow, and green color options, and for the Φ13.8 size, a 1.2Hz pulse (intermittent sound) output type is also available. Furthermore, the Φ32.8 series is IP68 rated for dust and water resistance.

The smallest buzzer and piezo sounder from CUI are newly introduced. They are ultra-compact SMT types that enable alarm functions in a compact form.

CUI Devices offers a lineup of buzzers, including the "Indicator" with a built-in drive circuit and the "Transducer" (Sounder) with an external drive circuit. We have released the smallest and thinnest Indicator to date, the "CMI-8536-82-SMT-TR," and the smallest piezo-type Transducer, the "CPT-7502-65-SMT-TR." Both models are surface mount types, making them easy to incorporate into portable and wearable applications due to their ability to sound in minimal space.

1.9mm thinnest piezo sounder new products CPT-9019A-SMT-TR, CPT-9019B-SMT-TR

A new model with a sound pressure of 72dB has been added to CUI's piezo buzzer (transducer with external drive circuit) in the smallest size of 9mm x 9mm. It is only 1.9mm thick, making it ideal for portable and wearable applications. It achieves a sound pressure of 72dB, which is more than double the previous 65dB for the same size, and the operating temperature has also been improved to -40℃ to +85℃, allowing for compatibility with a wider range of applications.

Recent introduction of magnetic buzzer products that have been frequently inquired about. Ideal for consideration of replacement from other companies due to widely used sizes and pin pitches.

We will introduce some of the magnetic buzzer products that have been frequently inquired about recently. We offer buzzer indicators that have a built-in drive circuit and sound when a DC voltage is applied, as well as transducers (sounders) that require an external drive circuit and can be used at your preferred frequency. These products come in widely used sizes and pin pitches, and their drive voltages make them suitable for consideration as replacements from other companies. At CUI, we continue to develop our product offerings while maintaining a sustainable supply of products through the establishment of a production system with a moderate MOQ, and we will strive to continue supporting our customers' development and production. Built-in circuit, pin type: CMI-1295-0585T 5V 85dB 2,300Hz φ12 x 9.5 CMI-1295-1285T 12V 85dB 2,300Hz φ12 x 9.5 CMI-1614-0685T 6V 85dB 2,200Hz φ16 x 14 CMI-1614-1285T 12V 85dB 2,200Hz φ16 x 14

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If you require a detailed technical explanation, please contact us.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.
