Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WT-1205 are qualified based on the following critical parameters:

• Rated voltage of 5V with compatible voltage operating range
• Frequency of 2.4kHz for audio tone consistency
• Through-hole mounting with PC pin termination for PCB integration
• 12mm diameter form factor for mechanical fit
• Externally driven transducer configuration
• ROHS3 compliance for regulatory alignment
• Sound pressure level within acceptable operational range (85dB minimum)

The identified substitutes AT-1224-TWT-R and CEM-1206S meet these core criteria while maintaining functional equivalence in the buzzer transducer category.

Parameter Comparison

Engineering Selection Recommendations

All three components—WT-1205, AT-1224-TWT-R, and CEM-1206S—maintain active production status and ROHS3 compliance, ensuring regulatory alignment and supply chain continuity. The WT-1205 delivers the highest sound pressure level at 87dB, while both substitute parts operate at 85dB. Current consumption differs across the three options: WT-1205 requires 50mA, AT-1224-TWT-R requires 40mA, and CEM-1206S requires 45mA. All three share identical 12mm diameter form factors and through-hole PC pin termination, confirming mechanical and electrical compatibility. The substitute parts offer extended operating temperature ranges, with AT-1224-TWT-R supporting -40°C to 70°C and CEM-1206S supporting -30°C to 70°C compared to the WT-1205 range of -20°C to 70°C.

Frequently Asked Questions (FAQ)

Q: Can AT-1224-TWT-R replace WT-1205 in existing designs?

A: Yes. Both components share 5V rated voltage, 2.4kHz frequency, 12mm diameter, through-hole mounting, and PC pin termination. The AT-1224-TWT-R operates at lower current (40mA vs. 50mA) and produces 2dB lower sound pressure level (85dB vs. 87dB). Verify that the 2dB reduction in acoustic output is acceptable for the application.

Q: What are the mechanical differences between these three buzzers?

A: All three components have identical 12mm diameter form factors and through-hole PC pin termination. Height differences are minimal: WT-1205 is 9.80mm, AT-1224-TWT-R is 8.70mm, and CEM-1206S is 10.00mm. These variations fall within typical PCB clearance tolerances.

Q: Which substitute offers the lowest power consumption?

A: AT-1224-TWT-R operates at 40mA, the lowest among the three options. WT-1205 requires 50mA, and CEM-1206S requires 45mA.

Q: Are all three parts ROHS3 compliant?

A: Yes. WT-1205, AT-1224-TWT-R, and CEM-1206S are all ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions.

Q: What is the difference in operating temperature ranges?

A: WT-1205 operates from -20°C to 70°C. AT-1224-TWT-R extends to -40°C to 70°C, and CEM-1206S operates from -30°C to 70°C. Select based on environmental operating conditions.

Q: Can CEM-1206S replace WT-1205?

A: Yes. CEM-1206S meets all core substitution criteria: 5V rated voltage, 2.4kHz frequency, 12mm diameter, through-hole mounting, and PC pin termination. Current consumption is 45mA, and sound pressure level is 85dB, both within acceptable operational parameters.
