Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AS07708PS-2-WR-R is determined by the following critical parameters:

• Impedance: 8 Ohms (electrical compatibility requirement)
• Power Rating: 4 W rated, 8 W maximum (thermal and acoustic performance)
• Frequency Range: 250 Hz ~ 10 kHz (acoustic bandwidth)
• Port Location: Top (mechanical and acoustic design)
• Physical Dimensions: 77.00 mm x 77.00 mm footprint, 28.00 mm maximum seated height (form factor compatibility)
• Termination Type: Solder Eyelet(s) (circuit integration)
• Ingress Protection: Water Resistant (environmental specification)

The AS07708PS-7-WR-R meets all critical substitution criteria, maintaining identical electrical specifications, mechanical dimensions, and environmental ratings while transitioning from Obsolete to Active product status.

Parameter Comparison

Engineering Selection Recommendations

The AS07708PS-7-WR-R is a direct substitute for the AS07708PS-2-WR-R. Both components are manufactured by PUI Audio, Inc. and maintain identical electrical, mechanical, and environmental specifications. The primary distinction is product status: the original part is Obsolete while the substitute is Active.

Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for new designs and legacy system support. The transition from AS07708PS-2-WR-R to AS07708PS-7-WR-R provides access to current manufacturing and supply chain continuity without requiring circuit redesign or acoustic performance adjustment.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical impedance (8 Ohms), power ratings (4 W rated, 8 W maximum), frequency response (250 Hz ~ 10 kHz), physical dimensions (77.00 mm x 77.00 mm, 28.00 mm height), and termination type (Solder Eyelet). No circuit modifications are required.

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

A: The AS07708PS-2-WR-R is classified as Obsolete, while AS07708PS-7-WR-R is Active. All electrical and mechanical specifications are identical. The part number change reflects manufacturing continuity and current product availability.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 and HTSUS 8518.29.8000. Regulatory status is equivalent.

Q: What are the critical parameters for substitution?

A: Impedance (8 Ohms), power rating (4 W), frequency range (250 Hz ~ 10 kHz), port location (Top), physical dimensions (77.00 mm x 77.00 mm), and termination type (Solder Eyelet) must remain constant for functional equivalence.

Q: Is the water resistant rating maintained in the substitute part?

A: Yes. Both AS07708PS-2-WR-R and AS07708PS-7-WR-R feature water resistant ingress protection and identical cone and magnet materials (Paper Coated and Ferrite respectively).
