AS04008PO-2 Equivalent & Substitute Parts

Part Overview

The AS04008PO-2 is an 8 Ohm general purpose speaker rated at 1 W with a frequency range of 450 Hz to 20 kHz, delivering 84 dBA sound pressure level. This component features a top port configuration with a round, rectangular frame and paper cone construction. The part is currently listed as obsolete, making identification of suitable substitutes essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AS04008PO-2 is determined by strict equivalence across the following critical parameters:

• Impedance: 8 Ohms (electrical matching requirement)
• Power Rating: 1 W rated, 2 W maximum (power handling compatibility)
• Frequency Response: 450 Hz ~ 20 kHz (acoustic performance specification)
• Self Resonant Frequency: 450 Hz (acoustic characteristic)
• Sound Pressure Level: 84 dBA at 1W/500mm (efficiency specification)
• Port Location: Top (mechanical and acoustic design constraint)
• Dimensions: 1.575" L x 1.114" W, 0.472" max height (form factor requirement)
• Termination: Solder Eyelet(s) (electrical connection compatibility)

The AS04008PO-2-R meets all substitution criteria while differing only in frame shape (oval versus round) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The AS04008PO-2-R is the direct substitute for the obsolete AS04008PO-2. Both components maintain identical electrical and acoustic specifications across impedance, power rating, frequency response, and efficiency parameters. The primary distinction is product status: AS04008PO-2-R is active and currently in production with 3865 units in stock, whereas AS04008PO-2 is obsolete with limited remaining inventory.

An additional compliance advantage exists with AS04008PO-2-R: it meets ROHS3 requirements, whereas the original AS04008PO-2 is RoHS non-compliant. For applications subject to RoHS regulations, AS04008PO-2-R is the required selection.

The frame shape difference (oval versus round) does not affect electrical or acoustic performance and is a mechanical design variation only. Both configurations maintain identical dimensions and mounting footprint.

Frequently Asked Questions (FAQ)

Q: Can AS04008PO-2-R be used as a direct replacement for AS04008PO-2?

A: Yes. Both parts are electrically and acoustically equivalent across all specified parameters: 8 Ohm impedance, 1 W rated power, 450 Hz ~ 20 kHz frequency range, 84 dBA efficiency, and identical physical dimensions. The frame shape difference (oval versus round) is a mechanical variation that does not affect performance.

Q: What is the significance of the product status difference?

A: AS04008PO-2 is obsolete with limited remaining inventory (1160 units). AS04008PO-2-R is active in production with substantially higher availability (3865 units). For new designs or ongoing production, AS04008PO-2-R is the recommended selection.

Q: Does the RoHS compliance difference matter?

A: Yes, if your application or market requires RoHS compliance. AS04008PO-2-R is ROHS3 compliant, while AS04008PO-2 is RoHS non-compliant. For regulated applications, AS04008PO-2-R is mandatory.

Q: Are the packaging differences significant?

A: AS04008PO-2-R is supplied in Tray packaging, while AS04008PO-2 packaging is unspecified. This affects handling and storage but does not impact component performance or compatibility.

Q: Will the oval frame shape affect my circuit design?

A: No. The frame shape is a mechanical design variation. Both round and oval configurations maintain the same electrical termination (Solder Eyelet(s)), dimensions (1.575" L x 1.114" W, 0.472" max height), and acoustic performance. Substitution is valid from an electrical and acoustic standpoint.
