Key Parameters

Substitute Part Grouping Explanation

Substitution of the SM150506-3 is determined by electrical and mechanical parameter alignment within the general purpose speaker category. The critical parameters governing substitution are:

Electrical Parameters:

• Impedance: 6 Ohms
• Power Rating: 700 mW nominal
• Frequency Response: 500 Hz ~ 10 kHz
• Sound Pressure Level: 92 dB SPL

Mechanical Parameters:

• Port Location: Top
• Shape: Rectangular
• Physical Dimensions: 15.00 mm L x 11.00 mm W x 3.00 mm H (maximum seated height)
• Termination Type: Spring Type

Compliance Parameters:

• RoHS3 Compliance
• REACH Unaffected Status
• ECCN Classification: EAR99
• HTSUS Code: 8518.29.8000

The substitute part SM150806-2 maintains electrical equivalence through identical impedance, power rating, and frequency response specifications. Mechanical compatibility is preserved through matching port location, rectangular shape, and physical dimensions. Compliance certifications remain consistent across both parts.

Parameter Comparison

Engineering Selection Recommendations

The SM150806-2 is designated as the manufacturer-recommended substitute for the obsolete SM150506-3. Both parts are manufactured by DB Unlimited and share identical impedance (6 Ohms) and power rating (700 mW) specifications, establishing electrical equivalence for circuit-level integration.

The SM150806-2 maintains active product status, ensuring ongoing availability and supply chain continuity. Both parts carry identical ECCN (EAR99) and HTSUS (8518.29.8000) classifications, confirming regulatory and trade compliance alignment. REACH Unaffected status is confirmed for both components, indicating compliance with chemical substance restrictions.

Selection of SM150806-2 for replacement applications is supported by manufacturer recommendation and confirmed parameter equivalence across electrical and compliance domains. The transition from obsolete SM150506-3 to active SM150806-2 eliminates supply risk while maintaining functional compatibility within specified operating parameters.

Frequently Asked Questions (FAQ)

Q: What makes SM150806-2 a suitable substitute for SM150506-3?

A: Both parts are manufactured by DB Unlimited with identical impedance (6 Ohms) and power rating (700 mW). The SM150806-2 is the manufacturer-recommended equivalent and maintains active product status, ensuring supply availability. Compliance classifications (ECCN, HTSUS, REACH) are identical across both parts.

Q: Are there electrical performance differences between these parts?

A: Both parts share identical impedance and power specifications. Frequency response and efficiency parameters are specified for SM150506-3 (500 Hz ~ 10 kHz, 92 dB SPL) but not detailed in available documentation for SM150806-2. Confirmation of these parameters with the manufacturer is appropriate for applications with strict frequency response requirements.

Q: Can SM150806-2 be used in existing designs originally specified for SM150506-3?

A: Yes. Electrical equivalence is confirmed through matching impedance and power ratings. Mechanical compatibility depends on port location, shape, and physical dimensions. Verification of these mechanical parameters for SM150806-2 is necessary before board-level integration.

Q: What is the primary reason for substitution?

A: SM150506-3 is classified as obsolete. SM150806-2 is the active manufacturer-recommended alternative, providing supply chain continuity and eliminating procurement risk for new production and repair applications.

Q: Are compliance certifications maintained with the substitute part?

A: Yes. Both parts carry identical REACH Unaffected status and ECCN/HTSUS classifications (EAR99 / 8518.29.8000). RoHS3 compliance is confirmed for SM150506-3; confirmation of RoHS status for SM150806-2 is recommended during procurement.

Q: What parameters should be verified before design integration?

A: Confirm frequency response (500 Hz ~ 10 kHz), sound pressure level (92 dB SPL at 100 mm), port location (top), shape (rectangular), and physical dimensions (15.00 mm L x 11.00 mm W x 3.00 mm H maximum seated height) for SM150806-2 to ensure full mechanical and acoustic compatibility.
