Substitute Part Grouping Explanation

Substitution of the AS05708PR-2-R is determined by the following critical parameters:

  • Impedance Match: 8 Ohms (electrical compatibility requirement)
  • Physical Compatibility: Round shape, 57.00mm diameter, top port location
  • Power Rating Compatibility: Rated power between 500 mW and 1.5 W (operational envelope overlap)
  • Frequency Response Overlap: Minimum frequency range compatibility within system bandwidth requirements
  • Termination Type: Solder connection capability

The PSR-57N08A01-AQ meets these substitution criteria through matching impedance, identical physical dimensions, compatible power ratings, and solder termination capability.

Engineering Selection Recommendations

The PSR-57N08A01-AQ is an active product with current manufacturing support and ROHS3 compliance, providing supply chain continuity for the obsolete AS05708PR-2-R. Both components share identical impedance and physical mounting dimensions, enabling direct mechanical and electrical substitution in most applications.

The PSR-57N08A01-AQ operates at a lower rated power (500 mW versus 1 W) and narrower frequency range (600 Hz ~ 4 kHz versus 350 Hz ~ 8 kHz). Applications requiring the full frequency response or maximum power rating of the original part must evaluate whether the substitute's operational envelope meets system requirements.

The substitute features a lower seated height (8.40mm versus 13.00mm), which may provide design flexibility in space-constrained applications. Termination differs from eyelet to solder pad configuration, requiring PCB layout adjustment.

Frequently Asked Questions (FAQ)

Q: Can the PSR-57N08A01-AQ directly replace the AS05708PR-2-R in existing designs?

A: Electrical substitution is possible due to matching 8 Ohm impedance and compatible power ratings. Mechanical substitution requires verification of PCB layout compatibility, as termination changes from solder eyelets to solder pads and seated height differs by 4.6mm.

Q: What are the frequency response implications of substitution?

A: The substitute operates across 600 Hz ~ 4 kHz versus the original 350 Hz ~ 8 kHz. Applications requiring response below 600 Hz or above 4 kHz must evaluate whether system performance remains acceptable within the substitute's bandwidth.

Q: How do power ratings affect substitution suitability?

A: The substitute is rated at 500 mW continuous versus 1 W for the original part. Both components share a 1 W maximum power overlap. Applications operating continuously above 500 mW must remain within the 1 W maximum specification of the substitute.

Q: Are there compliance differences between these components?

A: The PSR-57N08A01-AQ carries ROHS3 compliance certification. Both components maintain REACH Unaffected status. New designs should prioritize the substitute for regulatory compliance alignment.

Q: What termination changes are required for substitution?

A: The original part uses solder eyelets while the substitute uses solder pads. PCB design modifications are necessary to accommodate the different termination footprint.
