AW-10CSW Equivalent & Substitute Parts

Part Overview

The AW-10CSW is a piezo buzzer manufactured by PUI Audio, Inc., designed as an internally driven indicator with a 24V rated voltage and base mount configuration. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing system design and maintenance applications. The AW-10CSW operates across a voltage range of 9–28V with variable duration and pin-selectable operating modes, delivering 18mA supply current with IP33 ingress protection suitable for industrial and commercial applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AW-10CSW is determined by strict alignment of the following critical parameters:

Mandatory Matching Criteria:

• Manufacturer: PUI Audio, Inc. (same manufacturer, AW series)
• Technology: Piezo (internally driven indicator)
• Input Type: DC
• Voltage - Rated: 24 V
• Voltage Range: 9–28V (compatible operating envelope)
• Frequency: Multiple
• Operating Mode: Pin Selectable
• Duration: Variable
• Operating Temperature: −25°C to 70°C

Allowable Variations:

• Mounting Type: Base Mount (AW-10CSW) vs. Panel Mount with Flange (substitute) — both are mechanical interfaces within the same product family
• Current - Supply: 18mA (AW-10CSW) vs. 8–35mA (substitute) — substitute range encompasses the original specification
• Ingress Protection: IP33 (AW-10CSW) vs. IP65 (substitute) — substitute provides enhanced protection
• Sound Pressure Level: Not specified for AW-10CSW; substitute provides 88dB @ 24V, 100cm
• Product Status: Obsolete (AW-10CSW) vs. Active (substitute) — substitute maintains active production status

The AW-10FW qualifies as a direct substitute based on identical electrical specifications, compatible voltage envelope, and equivalent piezo technology within the same manufacturer series.

Parameter Comparison

Engineering Selection Recommendations

The AW-10FW is the qualified substitute for the obsolete AW-10CSW based on electrical and functional equivalence within the PUI Audio AW series. Both components share identical rated voltage (24V), voltage operating range (9–28V), piezo technology, internally driven indicator circuitry, pin-selectable operating modes, and variable duration capability. Both maintain compliance with REACH regulations and operate across the same temperature envelope (−25°C to 70°C).

The primary design consideration is the mechanical interface: the AW-10CSW uses base mount configuration, while the AW-10FW employs panel mount with flange and wire leads. System integration must account for this mounting topology change. The AW-10FW provides enhanced ingress protection (IP65 vs. IP33) and specified sound output (88dB @ 24V, 100cm), representing functional improvements over the original specification. The AW-10FW's current range (8–35mA) encompasses the AW-10CSW's 18mA specification, ensuring compatibility with existing power supply designs.

Frequently Asked Questions (FAQ)

Q: Can the AW-10FW directly replace the AW-10CSW without circuit modification?

A: Electrical substitution is direct due to identical voltage ratings, operating ranges, and DC input specifications. Mechanical integration requires accommodation of the different mounting interface: base mount (AW-10CSW) versus panel mount with flange (AW-10FW). Wire lead termination on the AW-10FW must be integrated into the existing connection scheme.

Q: What is the impact of the current specification difference (18mA vs. 8–35mA)?

A: The AW-10FW's current range encompasses the AW-10CSW's 18mA operating point. Power supply designs rated for 18mA operation remain valid. The broader range on the AW-10FW reflects manufacturing tolerance and operational flexibility without requiring circuit redesign.

Q: Does the enhanced ingress protection (IP65 vs. IP33) affect system compatibility?

A: No. IP65 (dust tight, water resistant) is a superset of IP33 (limited dust and water spray protection). The AW-10FW provides superior environmental protection suitable for the same or more demanding applications.

Q: Are there termination compatibility considerations?

A: The AW-10CSW termination is not specified in the available data. The AW-10FW uses wire leads, which are standard for piezo buzzer integration. Verify existing connection methodology and adapt as required for the wire lead interface.

Q: Is the size difference (86mm base vs. 52.5mm flange) a limiting factor?

A: Mechanical footprint differs significantly. The AW-10FW's smaller diameter (52.5mm) and comparable height (44.6mm vs. 42.5mm) may reduce mounting space requirements. Panel mount configuration requires different mechanical design than base mount. Evaluate enclosure and panel specifications for compatibility.

Q: Are both parts compliant with current regulatory standards?

A: Both the AW-10CSW and AW-10FW maintain REACH Unaffected status. The AW-10FW carries active product status, ensuring ongoing availability and compliance maintenance. The AW-10CSW's obsolete status limits future support and regulatory updates.
