Key Parameters

Substitute Part Grouping Explanation

The CMS-16098A-SP qualifies as a substitute for the CMS-16098-30-SP based on the following critical parameters:

Impedance matching: Both parts operate at 8 Ohms, ensuring electrical compatibility in circuits designed for the original component.

Mechanical compatibility: Both speakers share identical rectangular dimensions (16.00mm x 9.00mm) and maximum seated height (3.00mm), allowing direct physical replacement in existing PCB layouts.

Port configuration: Both feature top port location, maintaining acoustic design consistency.

Material composition: Both utilize Nd-Fe-B magnets and PET cone materials, ensuring comparable acoustic performance characteristics.

The CMS-16098A-SP represents an active product with enhanced specifications: rated power increased to 800 mW, efficiency improved to 88.00 dBA, and maximum power capacity maintained at 1 W. The substitute features a spring-type termination instead of solder pads, requiring consideration during integration.

Parameter Comparison

Engineering Selection Recommendations

The CMS-16098A-SP is the designated substitute for the obsolete CMS-16098-30-SP. Selection of this substitute is supported by:

Product status: The CMS-16098A-SP maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete original part.

Compliance: The substitute achieves ROHS3 compliance with REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

Electrical compatibility: Matching 8 Ohm impedance and 1 W maximum power rating ensure direct functional replacement in existing circuit designs.

Mechanical fit: Identical footprint dimensions and height specifications allow direct PCB layout compatibility without redesign.

Performance enhancement: The substitute delivers improved efficiency (88.00 dBA versus 87.50 dBA) and higher rated power (800 mW versus 700 mW), providing performance margin in the target application.

Termination consideration: The transition from solder pads to spring-type termination requires assembly process evaluation to confirm compatibility with existing manufacturing procedures.

Frequently Asked Questions (FAQ)

Q: Can the CMS-16098A-SP directly replace the CMS-16098-30-SP in existing designs?

A: Yes, the CMS-16098A-SP provides direct electrical and mechanical replacement. Both parts share identical impedance (8 Ohms), footprint dimensions (16.00mm x 9.00mm), and maximum seated height (3.00mm). The primary consideration is the termination type change from solder pads to spring type, which may require assembly process adjustment.

Q: What are the key differences between these two speakers?

A: The CMS-16098A-SP offers enhanced specifications: rated power increases from 700 mW to 800 mW, efficiency improves from 87.50 dBA to 88.00 dBA, and frequency range narrows from 400 Hz ~ 20 kHz to 467.5 Hz ~ 10 kHz. The substitute features spring-type termination instead of solder pads and maintains active product status versus obsolete status.

Q: Are there compliance differences between the original and substitute?

A: Yes. The CMS-16098-30-SP carries RoHS Compliant status, while the CMS-16098A-SP achieves ROHS3 Compliant status with REACH unaffected designation. Both parts maintain EAR99 ECCN classification and identical HTSUS codes.

Q: Does the frequency range difference affect substitution suitability?

A: The CMS-16098A-SP operates across a narrower frequency range (467.5 Hz ~ 10 kHz) compared to the original (400 Hz ~ 20 kHz). This difference must be evaluated against specific application frequency requirements to confirm acoustic performance compatibility.

Q: What termination type consideration applies to the substitute?

A: The CMS-16098A-SP uses spring-type termination instead of solder pads. This requires confirmation that existing PCB contact design and assembly processes accommodate spring-type connection methodology.
