GF0501M

Speakers Overview

The GF0501M is a general-purpose magnetic speaker manufactured by Same Sky. It features an 8-ohm impedance and a rated power of 250 mW, with a maximum power handling capacity of 500 mW. The unit utilizes a ferrite magnet and a polyester (PET) cone for sound generation. Its frequency response spans from 440 Hz to 5.8 kHz, with a self-resonant frequency of 440 Hz. The speaker delivers an efficiency of 86 dBA at 250 mW/500mm. Physically, it has a circular shape with a 50.00 mm diameter and a maximum installation height of 17.50 mm. Electrical connections are made via solder lug terminals.

Speakers Feature Summary

• Ferrite magnet construction for reliable performance
• Polyester cone material for durability

Speakers Applications

• General purpose audio output devices
• Medical equipment acoustic indicators
• Consumer electronics sound modules

Speakers Procurement Notes

Verify the manufacturer designation as Same Sky, formerly CUI Devices, to ensure accurate sourcing. Confirm RoHS3 compliance status during procurement checks. Ensure the ordering suffix matches the required terminal type and packaging configuration. Cross-reference the DigiKey part number 102-4757-ND or similar distributor codes for availability tracking. Validate that the component meets specific environmental requirements if deployed in regulated industries.

Speakers Selection Notes

Select this component when a compact, top-port speaker is required for general audio applications. The 8-ohm impedance suits standard amplifier outputs without complex matching networks. Consider the 50 mm diameter and 17.50 mm height for enclosure space constraints. The 86 dBA sensitivity provides adequate volume for non-high-fidelity uses. Verify that the operating temperature range meets the system's environmental demands.

Speakers Part Context

This speaker belongs to the GF series of standard audio components from Same Sky. The series offers various sizes and impedances for different acoustic needs. The GF0501M specifically targets applications requiring a balance between size and sound pressure level. It serves as a drop-in replacement for legacy CUI Devices speakers with identical form factors and electrical characteristics.

Speakers Replacement Considerations

Direct substitutes include other 50 mm diameter, 8-ohm, top-port speakers from the same manufacturer series. Verify pinout compatibility and mounting hole alignment when swapping brands. Ensure the replacement maintains the 86 dBA sensitivity to avoid volume discrepancies. Check that the new component supports the same voltage and power ratings to prevent damage.
