AW-15LPSBW Equivalent & Substitute Parts

Part Overview

The AW-15LPSBW is a piezoelectric buzzer manufactured by PUI Audio, Inc., designed for 24V DC applications with internally driven indicator functionality. This component features a 92mm base mount configuration and operates across a voltage range of 9–28V with pin-selectable operating modes and variable duration settings. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, maintenance, and new design implementations where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

The AW-15SBW qualifies as a functional substitute for the AW-15LPSBW based on the following critical parameters:

Matching Parameters:

• Manufacturer: PUI Audio, Inc. (same manufacturer ensures design continuity)
• Series: AW (same product family)
• Technology: Piezo (identical acoustic technology)
• Driver Circuitry: Indicator, Internally Driven (same control architecture)
• Input Type: DC (identical electrical input)
• Voltage - Rated: 24 V (same nominal operating voltage)
• Voltage Range: 9 ~ 28V (identical operating envelope)
• Frequency: Multiple (same frequency capability)
• Operating Mode: Pin Selectable (same mode selection)
• Duration: Variable (same duration control)
• Mounting Type: Base Mount (same mechanical interface)
• REACH Status: REACH Unaffected (same regulatory compliance)

Allowable Variations:

• Diameter: 3.661" (93.00mm) vs. 3.622" (92.00mm) — 0.039" difference within typical mechanical tolerance
• Height: 2.972" (75.50mm) vs. 2.500" (64.60mm) — increased height acceptable for base-mounted applications with adequate enclosure clearance
• Operating Temperature: -10°C ~ 60°C vs. -25°C ~ 70°C — narrower range suitable for standard industrial environments
• Ingress Protection: IP54 vs. IP65 — reduced protection level acceptable for controlled environments
• Product Status: Active vs. Obsolete — substitute is in active production

Parameter Comparison

Engineering Selection Recommendations

The AW-15SBW is the designated substitute for the obsolete AW-15LPSBW. Selection of this alternative is based on functional equivalence across all critical electrical and control parameters.

Substitution Validity: The AW-15SBW maintains electrical compatibility through identical rated voltage (24V), voltage range (9–28V), input type (DC), and control architecture (internally driven indicator with pin-selectable modes and variable duration). Both components utilize piezoelectric technology within the same AW series from PUI Audio, Inc., ensuring design continuity.

Mechanical Considerations: The substitute exhibits minor dimensional variations: diameter increases by 0.039 inches (1.0mm) and height increases by 12.0mm. These differences are within acceptable tolerances for base-mounted applications provided the enclosure or mounting surface accommodates the increased height. Verification of clearance in the target application is required.

Environmental Compliance: Both components maintain REACH Unaffected status. The substitute is RoHS3 compliant, whereas the main part does not specify RoHS status. The substitute's operating temperature range (-10°C to 60°C) is narrower than the main part (-25°C to 70°C); applications requiring operation below -10°C or above 60°C must be evaluated against actual system requirements.

Protection Rating: The substitute provides IP54 ingress protection compared to IP65 on the main part. IP54 classification remains suitable for dust-protected and water-resistant applications in controlled industrial environments. Applications requiring IP65-level protection must assess whether the reduced rating impacts system reliability.

Product Availability: The AW-15SBW is in active production status with documented inventory availability, ensuring long-term supply continuity compared to the obsolete AW-15LPSBW.

Frequently Asked Questions (FAQ)

Q: Can the AW-15SBW directly replace the AW-15LPSBW in existing designs?

A: Yes, the AW-15SBW provides functional electrical equivalence. Mechanical verification is required to confirm that the increased height (12.0mm) and diameter (1.0mm) do not conflict with enclosure constraints or mounting geometry in your specific application.

Q: What are the key electrical differences between these components?

A: There are no electrical differences. Both components operate at 24V rated voltage with a 9–28V operating range, utilize DC input, employ internally driven indicator circuitry with pin-selectable modes, and support variable duration control.

Q: Does the AW-15SBW meet the same environmental specifications?

A: The AW-15SBW meets REACH compliance equivalent to the AW-15LPSBW. The operating temperature range is narrower (-10°C to 60°C vs. -25°C to 70°C), and ingress protection is reduced (IP54 vs. IP65). Evaluate whether these differences impact your application's environmental requirements.

Q: What is the significance of the AW-15LPSBW being obsolete?

A: Obsolete status indicates the component is no longer manufactured. The AW-15SBW, in active production, provides functional continuity for new designs, maintenance replacements, and system upgrades where the original component is no longer available.

Q: Are there any compliance or certification differences?

A: Both components are REACH Unaffected. The AW-15SBW is explicitly RoHS3 compliant. The main part does not specify RoHS status. For applications requiring RoHS certification, the substitute provides documented compliance.

Q: What is the current consumption of these buzzers?

A: The AW-15LPSBW does not specify current consumption. The AW-15SBW operates at 6–33mA supply current. For power budget calculations, use the 6–33mA specification from the substitute.

Q: How do the sound pressure levels compare?

A: The AW-15LPSBW does not specify SPL. The AW-15SBW produces 84dB at 24V measured at 100cm. For acoustic performance requirements, reference the AW-15SBW specification.
