CLF0251MP Equivalent & Substitute Parts

Part Overview

The CLF0251MP is an 8 Ohm low profile speaker rated at 100 mW, manufactured by CUI Devices. This component operates across a frequency range of 650 Hz to 5 kHz with a sound pressure level of 70 dBA at 100 mW/500mm. The CLF0251MP is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

The CLS0231MP-1 qualifies as a functional substitute for the CLF0251MP based on the following critical parameters:

Matching Parameters:

• Impedance: 8 Ohms (identical)
• Power - Rated: 100 mW (identical)
• Power - Max: 200 mW (identical)
• Port Location: Top (identical)
• Shape: Round (identical)
• Termination: PC Pins (identical)
• Material - Cone: Polyester, Polyethylene Terephthalate (PET) (identical)
• RoHS Status: ROHS3 Compliant (identical)

Differing Parameters:

• Frequency Range: CLS0231MP-1 operates 384 Hz ~ 20 kHz versus CLF0251MP at 650 Hz ~ 5 kHz
• Efficiency - dBA: CLS0231MP-1 provides 72.00 dBA versus CLF0251MP at 70.00 dBA
• Size / Dimension: CLS0231MP-1 is 0.906" Dia (23.00mm) versus CLF0251MP at 0.984" Dia (25.00mm)
• Height - Seated (Max): CLS0231MP-1 is 0.197" (5.00mm) versus CLF0251MP at 0.220" (5.60mm)
• Material - Magnet: CLS0231MP-1 uses Nd-Fe-B versus CLF0251MP uses Ferrite
• Product Status: CLS0231MP-1 is Active versus CLF0251MP is Obsolete

Parameter Comparison

Engineering Selection Recommendations

The CLS0231MP-1 is the designated substitute for the obsolete CLF0251MP. Both components maintain identical electrical specifications for impedance, rated power, and maximum power ratings, ensuring circuit-level compatibility. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The CLS0231MP-1 offers improved acoustic performance with 72 dBA efficiency compared to 70 dBA for the CLF0251MP. The extended frequency range of 384 Hz to 20 kHz provides broader audio spectrum coverage relative to the CLF0251MP's 650 Hz to 5 kHz range. The CLS0231MP-1 uses neodymium-iron-boron (Nd-Fe-B) magnet technology versus ferrite in the CLF0251MP, contributing to the efficiency improvement.

Physical dimensions differ: the CLS0231MP-1 is slightly smaller at 23.00mm diameter and 5.00mm height compared to 25.00mm diameter and 5.60mm height for the CLF0251MP. Space-constrained applications must account for these dimensional changes. The CLS0231MP-1 is actively manufactured and stocked, providing supply continuity for new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Can the CLS0231MP-1 directly replace the CLF0251MP in existing designs?

A: Electrical compatibility is confirmed through matching impedance (8 Ohms), rated power (100 mW), and maximum power (200 mW) specifications. Physical dimensions differ, requiring verification of mechanical fit within the enclosure. The CLS0231MP-1 is smaller, which may require mounting bracket adjustment.

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

A: The primary differences are frequency response range, acoustic efficiency, magnet material, and physical dimensions. The CLS0231MP-1 covers 384 Hz to 20 kHz versus 650 Hz to 5 kHz for the CLF0251MP, and delivers 72 dBA versus 70 dBA efficiency. The CLS0231MP-1 uses Nd-Fe-B magnets while the CLF0251MP uses ferrite magnets.

Q: Does the CLS0231MP-1 meet the same compliance standards as the CLF0251MP?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8518.29.8000).

Q: What packaging is available for the CLS0231MP-1?

A: The CLS0231MP-1 is supplied in Tray packaging. The CLF0251MP packaging format is not specified in the available data.

Q: Is the CLS0231MP-1 currently in production?

A: Yes. The CLS0231MP-1 is classified as Active product status with 2914 pieces in stock. The CLF0251MP is obsolete with 1117 pieces remaining in inventory.
