Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the M3933/30-12N are determined by the following critical parameters:

• Package / Case: SMA In-Line Module (physical and electrical connector compatibility)
• Impedance: 50 Ohms (fundamental RF characteristic)
• Power Rating: 2W (thermal and handling capability)
• Frequency Range: Continuous operation from 0 Hz with upper frequency limit at or above the application requirement
• Attenuation Value: Fixed attenuation within acceptable tolerance for the intended circuit function

The LCAT1006-06 is listed as a parametric equivalent based on these core electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the M3933/30-12N and LCAT1006-06 are active products from established manufacturers. The M3933/30-12N maintains a broader frequency range extending to 32 GHz, while the LCAT1006-06 operates to 18 GHz with a 6 dB attenuation specification compared to the 5.5 dB of the main part. Selection between these components depends on the specific frequency requirements of the application. The M3933/30-12N is ROHS3 compliant; compliance status for the LCAT1006-06 is not provided in the available data. Both components share identical 2W power handling and 50 ohm impedance characteristics, as well as identical SMA in-line module packaging.

Frequently Asked Questions (FAQ)

Q: What makes LCAT1006-06 a substitute for M3933/30-12N?

A: Both components share the same SMA in-line module package format, 50 ohm impedance, and 2W power rating. These parameters define mechanical and electrical compatibility within RF attenuator applications.

Q: Are there differences in attenuation values between the main part and the substitute?

A: Yes. The M3933/30-12N specifies 5.5 dB attenuation while the LCAT1006-06 specifies 6 dB. This difference must be evaluated against the attenuation tolerance requirements of your circuit design.

Q: Does the frequency range difference affect substitution suitability?

A: The M3933/30-12N operates to 32 GHz while LCAT1006-06 operates to 18 GHz. Substitution suitability depends on your application's maximum operating frequency. The LCAT1006-06 is suitable only for applications operating at or below 18 GHz.

Q: What is the packaging format for both parts?

A: Both components are supplied in SMA in-line module configuration, providing identical mechanical integration and connector compatibility.

Q: Are both parts currently available?

A: Both M3933/30-12N and LCAT1006-06 maintain active product status with inventory availability confirmed at the time of this reference.
