Substitute Part Grouping Explanation

Substitution of the AS01808AO-3-SC-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) must be maintained
  • Mechanical Compatibility: Port location (top), shape (rectangular), and physical dimensions (18.00mm x 13.00mm) must be identical
  • Interface Compatibility: Termination type (spring type) must match for direct installation

The AS01808AO-SC18-WP-R meets all these criteria and is classified as a direct substitute. This part maintains identical electrical and acoustic specifications while offering improved product status (active vs. obsolete) and enhanced environmental protection (IP65 rating).

Engineering Selection Recommendations

The AS01808AO-SC18-WP-R is the direct substitute for the obsolete AS01808AO-3-SC-R. Both components are manufactured by PUI Audio, Inc. and maintain identical electrical, acoustic, and mechanical specifications across all critical parameters.

The substitute part offers the following advantages:

  • Active Product Status: The AS01808AO-SC18-WP-R is currently in active production, ensuring long-term availability and supply chain stability
  • Enhanced Environmental Protection: IP65 rating provides dust-tight and water-resistant performance, extending operational reliability in challenging environments
  • Regulatory Compliance: ROHS3 compliance and REACH unaffected status meet current environmental and safety standards
  • Reduced Height: The seated height is 0.008" (0.20mm) lower, providing improved mechanical fit in space-constrained applications

No functional or electrical compromise occurs with this substitution. The component is suitable for direct replacement in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the AS01808AO-SC18-WP-R be used as a direct replacement for the AS01808AO-3-SC-R?

A: Yes. Both components share identical impedance (8 Ohms), rated power (1 W), maximum power (1.2 W), frequency range (420 Hz ~ 14 kHz), port location (top), shape (rectangular), dimensions (18.00mm x 13.00mm), and spring-type termination. No circuit modifications or mechanical redesign is required.

Q: What is the difference in height between these two parts?

A: The AS01808AO-3-SC-R has a maximum seated height of 0.106" (2.70mm), while the AS01808AO-SC18-WP-R measures 0.098" (2.50mm). This 0.008" (0.20mm) reduction may provide improved fit in applications with tight vertical clearance constraints.

Q: Does the IP65 rating on the substitute part affect compatibility?

A: No. The IP65 rating (dust-tight, water-resistant) on the AS01808AO-SC18-WP-R is an enhancement that does not affect electrical or acoustic compatibility. It provides additional environmental protection without changing the component's core functionality.

Q: Are there packaging differences between these parts?

A: The AS01808AO-3-SC-R packaging is not specified in the available data. The AS01808AO-SC18-WP-R is supplied in tray packaging. Confirm packaging requirements with your procurement process.

Q: Is the substitute part RoHS compliant?

A: Yes. The AS01808AO-SC18-WP-R is ROHS3 compliant and REACH unaffected, meeting current environmental regulations. RoHS status for the original part is not specified.

Q: Why is the original part listed as obsolete?

A: The AS01808AO-3-SC-R is obsolete, meaning it is no longer in active production. The AS01808AO-SC18-WP-R is the active equivalent and should be used for new designs and ongoing production support.
