Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the PB-1820PL-06AQ is determined by the following critical parameters:

• Driver Circuitry: Externally driven transducer configuration
• Technology: Magnetic buzzer type
• Operating Mode: Single tone audio output
• Input Type: DC voltage operation
• Mounting Type: Through hole with PC pin termination
• Sound Pressure Level: Minimum 85dB @ rated voltage, 10cm distance
• Compliance: ROHS3 and REACH status alignment

The substitute part PB-12N23P-05AQ shares the same driver circuitry, technology, operating mode, input type, mounting configuration, and compliance certifications. However, it operates at a different rated voltage (5V versus 6V), resulting in different electrical operating parameters including current draw and voltage range specifications.

Parameter Comparison

Engineering Selection Recommendations

The PB-1820PL-06AQ is obsolete and no longer in active production. The PB-12N23P-05AQS is an active product from the same manufacturer series with identical compliance certifications (ROHS3 Compliant, REACH Unaffected).

Selection of PB-12N23P-05AQS as a substitute requires verification that the circuit design accommodates the 5V rated voltage specification instead of 6V. The substitute part operates within a 4V to 7V range, which overlaps with the original part's 3V to 10V range. The substitute delivers equivalent sound pressure output (85dB @ rated voltage, 10cm) and maintains the same externally driven magnetic transducer architecture.

The substitute part draws 30mA at rated voltage compared to 40mA for the original, and operates across a narrower temperature range (-20°C to 70°C versus -30°C to 70°C). Physical dimensions differ: the substitute is smaller in footprint (12mm diameter versus 18mm x 14mm rectangular) with comparable height specifications.

Frequently Asked Questions (FAQ)

Q: Can PB-12N23P-05AQS directly replace PB-1820PL-06AQ in existing designs?

A: Direct replacement requires circuit design compatibility with 5V operation. If the original design operates at 6V, the substitute will function within its 4V to 7V operating range, but output characteristics will be determined by the actual applied voltage. Both parts share identical driver circuitry, technology, and termination specifications.

Q: What are the physical compatibility considerations?

A: The substitute part has a smaller footprint (12mm diameter circular versus 18mm x 14mm rectangular). PCB layout and mounting hole spacing must accommodate the 12mm diameter configuration. Both parts use through-hole PC pin termination and have comparable seated heights (10.20mm versus 10.70mm).

Q: How do the electrical specifications differ?

A: The main part operates at 6V rated voltage with 40mA supply current. The substitute operates at 5V rated voltage with 30mA supply current. Both deliver 85dB sound pressure level at their respective rated voltages. The substitute's voltage range (4V to 7V) is narrower than the original (3V to 10V).

Q: Are both parts compliant with current regulations?

A: Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the frequency difference between these parts?

A: The main part operates at 2.25kHz while the substitute operates at 2.3kHz. Both are single-tone magnetic transducers with negligible frequency variation.
