Key Parameters

Substitute Part Grouping Explanation

Substitution of the AS04008PR-WR is determined by strict equivalence across all electrical and mechanical parameters. The substitute part AS04008PR-WR-R maintains identical specifications for impedance (8 Ohms), rated power (500 mW), maximum power (800 mW), frequency range (700 Hz ~ 4.8 kHz), self-resonant frequency (700 Hz), efficiency rating (94.00 dBA at 500mW/100mm), port location (top), shape (round), physical dimensions (1.575" diameter, 0.256" maximum seated height), cone material (paper coated), magnet material (Nd-Fe-B), ingress protection (water resistant), and termination method (solder pads).

The primary distinction between these parts is product status and packaging configuration, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The AS04008PR-WR-R is the direct substitute for the obsolete AS04008PR-WR. Both parts are manufactured by PUI Audio, Inc., and provide identical electrical and mechanical performance across all specified parameters. The AS04008PR-WR-R is currently in active production status with confirmed inventory availability, whereas the AS04008PR-WR is obsolete.

The AS04008PR-WR-R offers improved regulatory compliance, meeting ROHS3 requirements compared to the non-compliant status of the original part. Both parts maintain REACH Unaffected status and EAR99 export classification. The substitute part is supplied in Tray packaging, providing standard handling and storage configuration for production environments.

Frequently Asked Questions (FAQ)

Q: Can AS04008PR-WR-R be used as a direct replacement for AS04008PR-WR?

A: Yes. The AS04008PR-WR-R provides identical electrical performance (8 Ohm impedance, 500 mW rated power, 700 Hz ~ 4.8 kHz frequency range, 94 dBA efficiency) and mechanical specifications (40mm diameter, 6.5mm maximum height, top port, round shape, solder pad termination). Both parts use identical cone and magnet materials with water resistant ingress protection.

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

A: The AS04008PR-WR is obsolete with no active production, while AS04008PR-WR-R is in active production status. Additionally, AS04008PR-WR-R meets ROHS3 compliance requirements, whereas the original part is RoHS non-compliant. Packaging differs, with AS04008PR-WR-R supplied in Tray configuration.

Q: Are there any compatibility concerns when substituting AS04008PR-WR with AS04008PR-WR-R?

A: No compatibility concerns exist. Electrical impedance, power ratings, frequency response, efficiency, physical dimensions, and termination method are identical. The parts are mechanically and electrically interchangeable in all applications.

Q: What is the inventory status of the substitute part?

A: AS04008PR-WR-R has 4189 pieces available as new original stock. The original AS04008PR-WR has 1042 pieces remaining in inventory but is no longer in active production.

Q: Does the packaging change affect circuit board assembly?

A: No. Both parts use identical solder pad termination and physical dimensions. The Tray packaging of AS04008PR-WR-R is a standard production format that does not affect component performance or assembly compatibility.
