AS04008PR Equivalent & Substitute Parts

Part Overview

The AS04008PR is an 8 Ohm general purpose speaker manufactured by PUI Audio, Inc., rated for 500 mW continuous power with a frequency range of 700 Hz to 4.8 kHz. This speaker features a top-mounted round port, paper cone, and neodymium-iron-boron magnet construction, delivering 94 dB SPL at rated power. The AS04008PR is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The AS04008PR-R qualifies as a direct substitute based on matching electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Impedance: 8 Ohms (identical)
• Power rating: 500 mW continuous, 800 mW maximum (identical)
• Frequency range: 700 Hz ~ 4.8 kHz (identical)
• Efficiency: 94 dB SPL (identical)
• Port location: Top (identical)
• Shape: Round (identical)
• Diameter: 1.575" (40.00mm) (identical)
• Termination: Solder pads (identical)

The AS04008PR-R maintains full electrical and mechanical compatibility with the original part, differing only in product status (active vs. obsolete) and packaging configuration (tray vs. loose).

Parameter Comparison

Engineering Selection Recommendations

The AS04008PR-R is the direct equivalent for the obsolete AS04008PR. Selection of the AS04008PR-R is appropriate for new designs and component replenishment due to its active product status and ROHS3 compliance. The height difference of 0.012" (0.30mm) between the two parts is within typical mechanical tolerances for speaker mounting applications and does not affect electrical performance or functional compatibility.

For applications requiring RoHS non-compliant components, the original AS04008PR remains available in existing inventory. For new procurement and designs subject to RoHS regulations, the AS04008PR-R is the required selection.

Frequently Asked Questions (FAQ)

Q: Can the AS04008PR-R replace the AS04008PR in existing designs?

A: Yes. The AS04008PR-R is electrically and mechanically identical to the AS04008PR. All electrical parameters, impedance, power ratings, frequency response, and efficiency specifications match exactly. The minor height difference of 0.012" (0.30mm) is within standard mechanical tolerances for speaker mounting.

Q: What is the difference between the AS04008PR and AS04008PR-R?

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), packaging format (loose vs. tray), and seated height (0.256" vs. 0.268"). Electrical and acoustic performance are identical.

Q: Which part should be used for new designs?

A: The AS04008PR-R should be used for new designs. It is an active product with current manufacturing support and ROHS3 compliance, making it suitable for modern procurement and regulatory requirements.

Q: Are there any impedance or power rating differences between these parts?

A: No. Both parts are rated at 8 Ohms impedance, 500 mW continuous power, and 800 mW maximum power. Frequency response and efficiency specifications are identical.

Q: Does the packaging difference affect component performance?

A: No. Packaging format (tray vs. loose) affects handling and storage only. It does not impact electrical performance, acoustic characteristics, or functional compatibility in the application.
