Key Parameters

Substitute Part Grouping Explanation

The SMS-1508-2-R qualifies as a direct substitute based on identical electrical and mechanical parameters: 8 Ohm impedance, 300 mW rated power, 500 mW maximum power, 850 Hz to 20 kHz frequency range, 87.00 dBA efficiency, top port location, square shape, and matching 15.00mm x 15.00mm dimensions with 5.00mm maximum seated height. Both parts feature solder pad termination and are classified within the same SMS series. The substitution is valid across all applications where the SMS-1508-2 was specified.

Parameter Comparison

Engineering Selection Recommendations

The SMS-1508-2-R is the appropriate selection for new designs and production applications. The SMS-1508-2 is obsolete and should be replaced in active bill of materials. The SMS-1508-2-R maintains full electrical and mechanical compatibility while offering ROHS3 compliance, addressing regulatory requirements that the original part does not satisfy. Both parts carry identical REACH and ECCN classifications. The SMS-1508-2-R is available in Tape & Reel packaging, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Are SMS-1508-2 and SMS-1508-2-R electrically interchangeable? A: Yes. Both parts share identical impedance (8 Ohms), rated power (300 mW), maximum power (500 mW), frequency range (850 Hz ~ 20 kHz), and efficiency (87.00 dBA). Electrical performance is equivalent across all specified operating parameters.

Q: What is the primary difference between these parts? A: The SMS-1508-2-R is an active product with ROHS3 compliance, while the SMS-1508-2 is obsolete and RoHS non-compliant. The SMS-1508-2-R is supplied in Tape & Reel packaging for automated assembly.

Q: Can SMS-1508-2-R be used as a direct replacement in existing designs? A: Yes. Mechanical dimensions, termination type (solder pads), and all electrical parameters are identical. No circuit modifications are required.

Q: Are there packaging considerations when switching to SMS-1508-2-R? A: The SMS-1508-2-R is supplied in Tape & Reel format, which is standard for automated pick-and-place assembly. If manual assembly is required, verify that your assembly process supports this packaging format.

Q: Do both parts have the same moisture sensitivity rating? A: Yes. Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity precautions are necessary during storage or handling.
