Substitute Part Grouping Explanation

The AS02708CO-WR-R qualifies as a direct substitute based on matching electrical and mechanical parameters. Substitution criteria are determined by the following parameters:

  • Impedance: 8 Ohms (identical)
  • Power Rating: 1 W rated, 3 W maximum (identical)
  • Frequency Response: 250 Hz ~ 20 kHz (identical)
  • Sound Pressure Level: 80 dBA at 1W/500mm (identical)
  • Port Location: Top (identical)
  • Physical Form Factor: Oval, Rectangular Frame (identical)
  • Termination Type: Solder Eyelet(s) (identical)
  • Dimensions: 27.00mm x 20.00mm (identical)
  • Material Composition: Cloth cone, Nd-Fe-B magnet (identical)
  • Ingress Protection: Water Resistant (identical)

The primary distinction between the main part and substitute is product status and packaging configuration, with the substitute offering active product status and tray packaging.

Engineering Selection Recommendations

The AS02708CO-WR-R is the direct substitute for the obsolete AS02708CO-WR. All electrical and mechanical parameters are identical, ensuring functional equivalence in circuit applications. The substitute part offers the following advantages:

  • Active product status with established supply chain availability (56,374 units in stock versus 687 units for the obsolete part)
  • ROHS3 compliance, meeting current environmental and regulatory requirements
  • Tray packaging suitable for automated assembly processes
  • Marginal height increase of 0.012" (0.30mm) remains within typical PCB assembly tolerances

The height differential of 0.248" versus 0.236" should be evaluated against specific mechanical constraints in the target application. For applications with strict height limitations, this parameter requires verification against design specifications.

Frequently Asked Questions (FAQ)

Q: Are the AS02708CO-WR and AS02708CO-WR-R electrically interchangeable?

A: Yes. Both parts share identical electrical specifications: 8 Ohm impedance, 1 W rated power, 3 W maximum power, 250 Hz to 20 kHz frequency response, and 80 dBA efficiency. Circuit-level performance is equivalent.

Q: What is the significance of the height difference between these parts?

A: The AS02708CO-WR-R has a maximum seated height of 0.248" compared to 0.236" for the AS02708CO-WR, a difference of 0.012" (0.30mm). This minor variation should be evaluated against specific mechanical clearance requirements in the target assembly. Most applications accommodate this tolerance without modification.

Q: Why is the AS02708CO-WR obsolete?

A: The AS02708CO-WR is listed as obsolete product status. The AS02708CO-WR-R represents the active equivalent from the same manufacturer and series, offering continued availability and regulatory compliance.

Q: Does the packaging change affect compatibility?

A: The AS02708CO-WR-R is supplied in tray packaging, suitable for automated pick-and-place assembly. If manual assembly or alternative packaging is required, this should be confirmed with the supplier. The component itself is functionally identical regardless of packaging format.

Q: Are there compliance differences between these parts?

A: The AS02708CO-WR-R is ROHS3 compliant, while the AS02708CO-WR is RoHS non-compliant. Both maintain REACH Unaffected status. For applications subject to RoHS requirements, the AS02708CO-WR-R is the appropriate selection.

Q: Can the AS02708CO-WR-R be used in existing designs without modification?

A: Yes, for applications where the 0.30mm height increase does not create mechanical conflicts. Verify clearance against specific design constraints before implementation.
