Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AS01708MR-SC-R is determined by strict equivalence across the following critical parameters:

• Impedance: 8 Ohms (electrical matching requirement)
• Power Rating: 300 mW rated, 500 mW maximum (power handling compatibility)
• Frequency Range: 750 Hz ~ 5 kHz (acoustic performance specification)
• Self Resonant Frequency: 750 Hz (acoustic characteristic)
• Sound Pressure Level: 88 dBA at 100 mW/100 mm (efficiency specification)
• Port Location: Top (mechanical mounting requirement)
• Shape: Round (form factor requirement)
• Diameter: 0.669" (17.00 mm) (dimensional compatibility)
• Termination: Spring Type (electrical connection requirement)
• Cone Material: Polyester/PET (acoustic material specification)
• Magnet Material: Nd-Fe-B (magnetic performance specification)

The AS01708MR-SC-2-R meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The AS01708MR-SC-2-R is the qualified substitute for the obsolete AS01708MR-SC-R. Both components are manufactured by PUI Audio, Inc., and maintain identical electrical, acoustic, and mechanical specifications across all critical parameters.

The substitute part offers the advantage of active product status, ensuring ongoing availability and supply chain continuity. The AS01708MR-SC-2-R carries RoHS3 compliance certification, providing enhanced environmental and regulatory alignment for new designs and procurement cycles.

The seated height differential of 0.40 mm (4.80 mm versus 4.40 mm) represents a minor mechanical variation that does not affect electrical or acoustic performance. This dimension should be verified against specific mechanical mounting constraints in the target application.

Frequently Asked Questions (FAQ)

Q: Can the AS01708MR-SC-2-R be used as a direct replacement for the AS01708MR-SC-R?

A: Yes. Both components share identical impedance (8 Ohms), power ratings (300 mW rated, 500 mW maximum), frequency response (750 Hz ~ 5 kHz), efficiency (88 dBA), port location (top), shape (round), diameter (17.00 mm), and termination type (spring). All critical electrical and acoustic parameters are equivalent.

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

A: The primary differences are product status and packaging. The AS01708MR-SC-R is obsolete with spring termination packaging, while the AS01708MR-SC-2-R is an active product supplied in tray packaging. The AS01708MR-SC-2-R also includes RoHS3 compliance certification. The seated height differs by 0.40 mm, which may require verification against mechanical mounting specifications.

Q: Are there any compliance or regulatory differences?

A: Both parts maintain REACH Unaffected status and EAR99 ECCN classification. The AS01708MR-SC-2-R carries RoHS3 compliance, providing additional environmental regulatory alignment.

Q: Does the height difference affect compatibility?

A: The AS01708MR-SC-2-R has a maximum seated height of 4.40 mm compared to 4.80 mm for the AS01708MR-SC-R. This 0.40 mm reduction should be evaluated against specific mechanical mounting clearances and enclosure constraints in the target application to confirm fit.

Q: What is the inventory status for these parts?

A: The AS01708MR-SC-R has 789 pieces in stock as new original inventory. The AS01708MR-SC-2-R has 1,035 pieces in stock as new original inventory, providing greater supply availability.
