PB-2317 Equivalent & Substitute Parts

Part Overview

The PB-2317 is a piezoelectric buzzer manufactured by Soberton Inc., designed as an externally driven transducer for 12V DC applications. It operates at 3.7kHz with a sound pressure level of 90dB at 12V measured at 30cm, drawing 8mA of supply current. The component features a 23mm flange-mounted design with wire lead termination for panel integration.

The PB-2317 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality and ensure continued availability for new production runs, repairs, and field replacements where the original component is no longer procurable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PB-2317 is based on the following critical parameters that must align for functional compatibility:

Electrical Parameters:

• Rated voltage: 12V DC
• Voltage operating range: 3 ~ 16V
• Supply current: 8mA
• Frequency: 3.7kHz
• Technology: Piezo

Mechanical Parameters:

• Mounting type: Panel Mount, Flange
• Diameter: 23mm (0.906")
• Termination: Wire Leads
• Port location: Top

Environmental Parameters:

• Operating temperature range: -20°C ~ 60°C
• RoHS3 compliance

The substitute part AI-2337-TF-LW115-R from PUI Audio, Inc. meets all critical electrical, mechanical, and environmental parameters. The primary functional difference is the driver circuitry classification (internally driven versus externally driven) and the measured sound pressure level specification (100dB @ 12V, 10cm versus 90dB @ 12V, 30cm). Both components operate at identical rated voltage, frequency, and current consumption, with compatible physical form factors and mounting interfaces.

Parameter Comparison

Engineering Selection Recommendations

The AI-2337-TF-LW115-R is the identified substitute for the obsolete PB-2317. Both components are ROHS3 compliant and operate within identical electrical specifications: 12V rated voltage, 3 ~ 16V operating range, 8mA supply current, and 3.7kHz frequency. Both feature compatible 23mm flange-mounted panel designs with wire lead termination and identical operating temperature ranges of -20°C to 60°C.

The AI-2337-TF-LW115-R is currently in active production status with substantial inventory availability (12,415 pcs), ensuring procurement reliability. The component maintains mechanical compatibility with the original PB-2317 mounting interface, with a maximum seated height of 0.689" (17.50mm) compared to 0.669" (17.00mm) for the original part—a difference of 0.020" that remains within typical panel mount tolerances.

The substitute part is suitable for direct replacement in applications where the PB-2317 is no longer available, provided the system design accommodates the internally driven indicator configuration and the measured sound pressure level specification of 100dB @ 12V, 10cm.

Frequently Asked Questions (FAQ)

Q: Can the AI-2337-TF-LW115-R directly replace the PB-2317 in existing designs?

A: Yes, the AI-2337-TF-LW115-R meets all critical electrical and mechanical parameters for substitution. Both components operate at 12V rated voltage, 8mA supply current, and 3.7kHz frequency. The 23mm flange-mounted form factor and wire lead termination are identical. The maximum seated height difference of 0.020" is typically accommodated within standard panel mount tolerances.

Q: What is the difference between externally driven and internally driven driver circuitry?

A: The PB-2317 is classified as an externally driven transducer, while the AI-2337-TF-LW115-R is an internally driven indicator. This classification reflects the internal circuit architecture. Both components operate at the same rated voltage and frequency, and both are compatible with 12V DC power supplies.

Q: How do the sound pressure level specifications compare?

A: The PB-2317 produces 90dB @ 12V measured at 30cm, while the AI-2337-TF-LW115-R produces 100dB @ 12V measured at 10cm. The different measurement distances make direct comparison complex; however, both components are suitable for audible alarm and indicator applications in standard industrial and consumer electronics environments.

Q: Are there packaging considerations for the substitute part?

A: The AI-2337-TF-LW115-R is supplied in tray packaging, whereas the original PB-2317 packaging specification is not detailed. Tray packaging is standard for piezoelectric buzzer components and is compatible with automated assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes, both the PB-2317 and AI-2337-TF-LW115-R are ROHS3 compliant. Both components are classified under ECCN EAR99 and HTSUS 8531.80.9041. The AI-2337-TF-LW115-R additionally carries REACH Unaffected status.

Q: What is the operating temperature range for both components?

A: Both the PB-2317 and AI-2337-TF-LW115-R operate across an identical temperature range of -20°C to 60°C, ensuring compatibility in standard industrial and consumer applications.
