AS01808AO-SC-WP-R Equivalent & Substitute Parts

Part Overview

The AS01808AO-SC-WP-R is an 8 Ohm general purpose speaker rated at 1 W with a top rectangular port configuration, manufactured by PUI Audio, Inc. as part of the Slim Line Micro series. This speaker delivers 94 dB sound pressure level (SPL) at 1W/100mm across a frequency range of 420 Hz to 14 kHz, with IP65 ingress protection for dust and water resistance. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system support and component replacement in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AS01808AO-SC-WP-R is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Impedance (8 Ohms), rated power (1 W), and maximum power (1.2 W) must match exactly
• Acoustic Performance: Frequency range (420 Hz ~ 14 kHz) and efficiency (94 dB SPL at 1W/100mm) must be identical
• Mechanical Compatibility: Port location (top), shape (rectangular), and physical dimensions (18.00mm L x 13.00mm W, 2.50mm max height) must align with PCB layout and enclosure constraints
• Environmental Specifications: IP65 ingress protection rating and spring-type termination must be maintained
• Material Specifications: Polyester/PET cone material and Nd-Fe-B magnet composition ensure consistent acoustic and thermal characteristics

The AS01808AO-SC18-WP-R meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The AS01808AO-SC18-WP-R is the appropriate substitute for the obsolete AS01808AO-SC-WP-R. Both components are electrically and mechanically identical across all specified parameters. The substitute part offers the additional advantage of active product status, ensuring continued availability and supply chain reliability. The AS01808AO-SC18-WP-R carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for new designs and production runs. Packaging differs (tray for the substitute versus unspecified for the main part), but this does not affect functional compatibility or performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the AS01808AO-SC18-WP-R be used as a direct replacement for the AS01808AO-SC-WP-R?

A: Yes. Both parts are electrically and mechanically equivalent. All critical parameters—impedance, power rating, frequency response, efficiency, port location, dimensions, and termination type—are identical. The substitute is the active production equivalent.

Q: What is the difference between these two part numbers?

A: The primary difference is product status. The AS01808AO-SC-WP-R is obsolete, while the AS01808AO-SC18-WP-R is active. The substitute also includes ROHS3 compliance and REACH unaffected certification. Packaging differs (tray for the substitute), but electrical and acoustic performance are identical.

Q: Are there any compatibility concerns with PCB layout or mechanical mounting?

A: No. Both parts share identical dimensions (18.00mm L x 13.00mm W, 2.50mm max height), rectangular shape, top port location, and spring-type termination. Direct PCB substitution is possible without layout modifications.

Q: Does the substitute part meet environmental and regulatory requirements?

A: Yes. The AS01808AO-SC18-WP-R is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: What is the impedance and power rating for both parts?

A: Both parts are rated at 8 Ohms impedance with 1 W nominal power and 1.2 W maximum power handling. Frequency response spans 420 Hz to 14 kHz with 94 dB SPL efficiency at 1W/100mm.
