Key Parameters

Substitute Part Grouping Explanation

The CMS-15116-SP qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

• Impedance: 6 Ohms (identical)
• Power - Rated: 940 mW (identical)
• Power - Max: 1.3 W (identical)
• Port Location: Top (identical)
• Shape: Rectangular (identical)
• Size / Dimension: 0.591" L x 0.433" W / 15.00mm x 11.00mm (identical)
• Material - Cone: Polyester, Polyethylene Terephthalate (PET) (identical)
• Material - Magnet: Nd-Fe-B (identical)

Differing Parameters:

• Frequency Range: 467.5 Hz ~ 15 kHz (vs. 400 Hz ~ 20 kHz)
• Efficiency - dBA: 89.00 (vs. 94.00)
• Height - Seated (Max): 0.118" / 3.00mm (vs. 0.130" / 3.30mm)
• Termination: Spring Type (vs. Solder Pads)
• Product Status: Active (vs. Obsolete)

The substitute maintains electrical and mechanical compatibility through identical impedance, power ratings, footprint dimensions, and magnetic construction. Differences in frequency response, efficiency rating, and termination type must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The CMS-15116-SP is an active production alternative to the obsolete CMS-15116-30-SP. Both components share identical electrical specifications (6 Ohm impedance, 940 mW rated power) and mechanical footprint (15.00mm x 11.00mm). The substitute maintains RoHS compliance through ROHS3 certification, exceeding the original RoHS Compliant status.

Selection between these parts depends on application-specific constraints:

Choose CMS-15116-30-SP when:

• Original design specifications require solder pad termination
• Full frequency response from 400 Hz is mandatory
• 94 dB efficiency rating is a design requirement
• Maximum height of 3.30mm is required

Choose CMS-15116-SP when:

• Spring type termination is acceptable or preferred
• Frequency response of 467.5 Hz to 15 kHz meets application needs
• 89 dB efficiency is sufficient for the application
• Lower profile (3.00mm) provides design advantage
• Active production status and availability are priorities

Frequently Asked Questions (FAQ)

Q: Can CMS-15116-SP directly replace CMS-15116-30-SP in existing designs?

A: Direct replacement is possible only if the application tolerates differences in termination type (spring vs. solder pads), frequency response range (467.5 Hz ~ 15 kHz vs. 400 Hz ~ 20 kHz), and efficiency rating (89 dB vs. 94 dB). Electrical compatibility is confirmed through identical impedance and power ratings.

Q: What is the primary difference between these two parts?

A: The CMS-15116-SP is classified as a low profile variant with spring type termination and reduced height (3.00mm vs. 3.30mm). The original CMS-15116-30-SP uses solder pad termination and delivers higher efficiency (94 dB vs. 89 dB) across a wider frequency range (400 Hz ~ 20 kHz vs. 467.5 Hz ~ 15 kHz).

Q: Are both parts RoHS compliant?

A: Yes. The CMS-15116-30-SP is RoHS Compliant. The CMS-15116-SP meets the more recent ROHS3 Compliant standard, providing enhanced environmental compliance.

Q: Does the frequency range difference affect compatibility?

A: The CMS-15116-SP has a narrower frequency range (467.5 Hz ~ 15 kHz) compared to the original (400 Hz ~ 20 kHz). Applications requiring response below 467.5 Hz or above 15 kHz must retain the original part or evaluate system-level impact.

Q: What termination type should I select?

A: The CMS-15116-30-SP uses solder pads for permanent PCB attachment. The CMS-15116-SP uses spring type termination for removable or flexible mounting. Select based on your assembly and serviceability requirements.

Q: Is the 5 dB efficiency difference significant?

A: The CMS-15116-30-SP delivers 94 dB SPL while the CMS-15116-SP delivers 89 dB SPL at identical power levels (940 mW/100mm). This 5 dB difference represents approximately 68% less acoustic output. Evaluate against application audio requirements.
