Procurement Notes

Verify the specific ordering suffix and manufacturer part number against official PUI Audio documentation before procurement. Confirm that the 4 Ohm impedance and 2 W power rating align with your circuit design requirements. Ensure compatibility with the specified solder eyelet termination method during assembly planning. Check current RoHS compliance status through the manufacturer's latest datasheet or certification documents.

Selection Notes

Select this component when a rectangular form factor is required for space-constrained designs. The 4 Ohm impedance offers distinct matching characteristics compared to standard 8 Ohm alternatives. Consider the -40 C to +80 C operating range for environments with significant thermal variations. The paper cone material provides specific acoustic damping properties suitable for general voice reproduction tasks.

Part Context

This model belongs to the AS series of speakers from PUI Audio, which focuses on electromagnetic transducers for various electronic devices. The series includes various shapes and sizes, with this specific unit representing the rectangular variant optimized for board-level integration. It serves as a fundamental audio output component in portable and stationary electronic equipment.

Replacement Considerations

Direct substitutes must match the 40x28.5mm rectangular footprint, 4 Ohm impedance, and 2W power rating. Verify that alternative components support solder eyelet termination and operate within the same temperature limits. Cross-reference mechanical drawings to ensure hole patterns and depth constraints are met without modifying the host PCB layout.
