Key Parameters

Substitute Part Grouping Explanation

Substitution of the AS07708PS-2-R is determined by strict equivalence across the following critical parameters:

• Impedance: 8 Ohms (electrical interface requirement)
• Power Rating: 4 W rated / 8 W maximum (power handling capacity)
• Frequency Range: 250 Hz ~ 10 kHz (acoustic performance specification)
• Self Resonant Frequency: 250 Hz (acoustic characteristic)
• Efficiency: 90 dB SPL at 1W/500mm (acoustic output specification)
• Port Location: Top (mechanical and acoustic design)
• Physical Dimensions: 77.00mm x 77.00mm x 27.00mm maximum height (form factor and mounting)
• Termination Type: Solder Eyelet(s) (electrical connection method)
• Material Composition: Paper cone, Ferrite magnet (acoustic and mechanical properties)

The AS07708PS-7-R meets all these critical parameters and is designated as the manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The AS07708PS-7-R is the direct equivalent substitute for the obsolete AS07708PS-2-R. Both parts are manufactured by PUI Audio, Inc., and maintain identical electrical, acoustic, and mechanical specifications across all critical parameters. The AS07708PS-7-R carries Active product status, ensuring continued availability and supply chain reliability. Both parts maintain ROHS3 compliance and are classified as REACH Unaffected, meeting current environmental and regulatory requirements. The AS07708PS-7-R is supplied in Tray packaging, which may differ from the original part's packaging configuration but does not affect functional compatibility or performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the AS07708PS-7-R be used as a direct replacement for the AS07708PS-2-R?

A: Yes. The AS07708PS-7-R is the manufacturer-recommended substitute and maintains identical specifications across impedance, power rating, frequency response, efficiency, physical dimensions, and termination type. No circuit modifications or design changes are required.

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

A: The primary difference is product status. The AS07708PS-2-R is obsolete, while the AS07708PS-7-R is active. Both parts are electrically and mechanically equivalent. The AS07708PS-7-R is supplied in Tray packaging.

Q: Are there any compatibility concerns when substituting the AS07708PS-7-R?

A: No compatibility concerns exist. Both parts share identical impedance (8 Ohms), power handling (4 W rated), frequency response (250 Hz ~ 10 kHz), acoustic efficiency (90 dB SPL), physical dimensions (77mm x 77mm x 27mm), and termination method (Solder Eyelet). The parts are form-fit-function equivalent.

Q: Does the packaging difference affect performance?

A: No. Packaging type (Tray for the AS07708PS-7-R) does not affect electrical or acoustic performance. Packaging differences relate only to handling, storage, and logistics considerations.

Q: Are both parts RoHS compliant?

A: Yes. Both the AS07708PS-2-R and AS07708PS-7-R are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.
