Key Parameters

Substitute Part Grouping Explanation

Substitute parts are qualified based on the following critical parameters that must remain consistent for direct compatibility:

• Voltage Rating: 5V nominal operation with 1~30V tolerance range
• Frequency: 4kHz nominal output frequency
• Technology: Piezo transducer type
• Driver Circuitry: Externally driven configuration
• Input Type: Peak-Peak signal input
• Mounting Type: Through Hole with PC Pin termination
• Compliance: ROHS3 Compliant status

The TP124005-2 qualifies as a direct substitute based on these parameters. Dimensional variations and sound pressure level differences remain within acceptable tolerances for this component category, with the substitute maintaining equivalent electrical functionality and interface compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TP124005-2 is the qualified substitute for the TP124005-1. Both parts maintain ROHS3 compliance and identical electrical specifications across voltage rating, frequency, current consumption, and signal input type. The TP124005-2 offers the additional advantage of Active product status, ensuring long-term procurement availability and manufacturing support.

Dimensional differences (diameter reduction from 12.80mm to 12.20mm; height reduction from 7.80mm to 7.50mm) are compatible with standard through-hole footprints. The TP124005-2 provides a 5dB reduction in sound pressure level (75dB versus 80dB at 5V, 10cm), which must be evaluated against application acoustic requirements. The extended operating temperature range of the TP124005-2 (-20°C to 70°C versus -20°C to 60°C) provides improved thermal performance margins.

Frequently Asked Questions (FAQ)

Q: Can TP124005-2 directly replace TP124005-1 on existing PCBs? A: Yes. Both parts use identical Through Hole PC Pin termination and maintain compatible dimensional tolerances for standard footprint placement. Minor dimensional differences do not affect mounting or electrical connectivity.

Q: What is the significance of the 5dB sound pressure level difference? A: The TP124005-2 produces 75dB at 5V measured at 10cm, compared to 80dB for the TP124005-1. Applications requiring the original 80dB output specification must evaluate whether this reduction meets system acoustic requirements.

Q: Are both parts equally suitable for temperature-sensitive applications? A: The TP124005-2 operates to 70°C maximum, compared to 60°C for the TP124005-1. For applications requiring operation at or above 60°C, the TP124005-2 provides superior thermal margin. For applications limited to 60°C or below, both parts are functionally equivalent.

Q: Why is TP124005-1 marked Obsolete if TP124005-2 is available? A: TP124005-1 is no longer manufactured. TP124005-2 is the current Active production equivalent and serves as the recommended replacement for new designs and ongoing procurement.

Q: Do both parts require identical driving circuits? A: Yes. Both parts are externally driven piezo transducers with Peak-Peak signal input and identical voltage specifications (5V rated, 1~30V operating range). Existing drive circuits for TP124005-1 are directly compatible with TP124005-2.
