AS03608MR-3-R Equivalent & Substitute Parts

Part Overview

The AS03608MR-3-R is an 8 Ohm general purpose speaker manufactured by PUI Audio, Inc., rated for 500 mW power handling with a top-mounted round port configuration. This component operates across a 650 Hz to 7 kHz frequency range and delivers 83 dBA sound pressure level at 1W/1M testing conditions. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations where this speaker specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

The AS03608MR-4-R qualifies as a direct substitute for the AS03608MR-3-R based on the following critical parameters:

Matching Parameters:

• Impedance: 8 Ohms (identical)
• Port Location: Top (identical)
• Shape: Round (identical)
• Size / Dimension: 1.417" Dia (36.00mm) (identical)
• Material - Cone: Polyester, Polyethylene Terephthalate (PET) (identical)
• Material - Magnet: N35 (identical)
• Termination: Solder Pads (identical)
• Technology: Magnetic (identical)
• Type: General Purpose (identical)

Allowable Parameter Variations:

• Power - Rated: 800 mW (increased from 500 mW)
• Power - Max: 1 W (increased from 700 mW)
• Frequency Range: 450 Hz ~ 20 kHz (expanded from 650 Hz ~ 7 kHz)
• Frequency - Self Resonant: 450 Hz (decreased from 650 Hz)
• Efficiency - dBA: 85.00 (increased from 83.00)
• Height - Seated (Max): 0.169" (4.30mm) (decreased from 0.193" (4.90mm))

The AS03608MR-4-R maintains identical mechanical form factor and electrical interface while providing enhanced power handling capability and extended frequency response, making it suitable for applications requiring the AS03608MR-3-R specification.

Parameter Comparison

Engineering Selection Recommendations

The AS03608MR-4-R is the active production equivalent for the obsolete AS03608MR-3-R. Selection of the AS03608MR-4-R is appropriate for applications where the AS03608MR-3-R specification is required, as it maintains identical mechanical mounting, electrical interface, and core acoustic characteristics while offering improved performance margins.

The AS03608MR-4-R carries ROHS3 compliance certification, whereas the AS03608MR-3-R status is not specified. Both parts maintain REACH Unaffected status and EAR99 export classification. The reduced seated height of the AS03608MR-4-R (0.169" versus 0.193") must be evaluated against mechanical enclosure constraints in applications with tight vertical clearance requirements.

Frequently Asked Questions (FAQ)

Q: Can the AS03608MR-4-R directly replace the AS03608MR-3-R in existing designs?

A: Yes. The AS03608MR-4-R maintains identical impedance (8 Ohms), mechanical form factor (1.417" diameter round), port location (top), and solder pad termination. The 0.024" reduction in seated height must be verified against enclosure specifications.

Q: What are the key differences between these two speaker models?

A: The AS03608MR-4-R provides 60% higher rated power handling (800 mW versus 500 mW), extended frequency response (450 Hz to 20 kHz versus 650 Hz to 7 kHz), and 2 dBA higher efficiency. The AS03608MR-3-R is obsolete; the AS03608MR-4-R is in active production.

Q: Are there impedance or electrical interface compatibility concerns?

A: No. Both parts are 8 Ohm speakers with identical solder pad termination. Electrical interface is fully compatible.

Q: Does the frequency response difference affect substitution suitability?

A: The AS03608MR-4-R extends frequency response in both directions (lower self-resonant frequency at 450 Hz and upper range to 20 kHz). Applications designed for the 650 Hz to 7 kHz range of the AS03608MR-3-R operate within the AS03608MR-4-R's frequency capability.

Q: What compliance certifications apply to each part?

A: The AS03608MR-4-R is ROHS3 compliant. Both parts are REACH Unaffected and classified as EAR99 for export purposes.

Q: Are packaging differences relevant to component selection?

A: The AS03608MR-3-R packaging is listed as dash (-). The AS03608MR-4-R is supplied in bulk packaging. Verify packaging requirements for procurement and handling procedures.
