Substitute Part Grouping Explanation

Substitute parts for the AT-106V are classified based on strict alignment with the following critical parameters:

Primary Substitution Criteria:

Attenuation Value: 6dB (exact match required)
Frequency Range: 0 Hz ~ 18 GHz (minimum coverage)
Impedance: 50 Ohms (exact match required)
Package / Case: SMA In-Line Module (exact match required)
Power Rating: 2W (where specified)

Grouping Logic:

Group 1: Full Parametric Equivalents (All parameters match AT-106V)

32AS102-K06S3 (Rosenberger): Matches all electrical and mechanical parameters; Active product status
LCAT1006-06 (L-com): Matches all electrical and mechanical parameters; Active product status
M3933/16-02S (Cinch Connectivity Solutions Midwest Microwave): Matches all electrical and mechanical parameters; Active product status

Group 2: Frequency-Limited Substitutes (6dB, 50 Ohm, SMA, but 0 Hz ~ 12.4 GHz)

M3933/14-02N (Cinch Connectivity Solutions Midwest Microwave): Reduced frequency range; power rating not specified
M3933/14-02S (Cinch Connectivity Solutions Midwest Microwave): Reduced frequency range; power rating not specified

Group 3: Attenuation Variance Substitutes (6.5dB instead of 6dB)

M3933/16-23N (Cinch Connectivity Solutions Midwest Microwave): 6.5dB attenuation; matches frequency, impedance, power, and package
M3933/16-23S (Cinch Connectivity Solutions Midwest Microwave): 6.5dB attenuation; matches frequency, impedance, power, and package

Group 4: Military-Grade Equivalent (Full frequency coverage, unspecified power)

M3933/16-02N (Cinch Connectivity Solutions Midwest Microwave): MIL-DTL-M3933 qualified; 0 Hz ~ 18 GHz; power rating not specified

Engineering Selection Recommendations

For Direct Replacement (Full Parametric Match):

32AS102-K06S3 and LCAT1006-06 are the primary substitutes, both offering identical electrical specifications (6dB, 0 Hz ~ 18 GHz, 2W, 50 Ohm, SMA In-Line Module) with Active product status. Both manufacturers maintain current production and inventory availability. 32AS102-K06S3 maintains RoHS compliance matching the AT-106V. LCAT1006-06 provides equivalent performance with 998 units in stock.

M3933/16-02S (Cinch Connectivity Solutions Midwest Microwave) provides full parametric equivalence with 902 units available and Active status, though RoHS non-compliance should be evaluated against system requirements.

For Frequency-Limited Applications (DC to 12.4 GHz):

M3933/14-02N and M3933/14-02S are suitable only for applications not exceeding 12.4 GHz. Both maintain 6dB attenuation and 50 Ohm impedance with SMA In-Line Module packaging. Power rating is not specified for these parts.

For Military Applications:

M3933/16-02N carries MIL-DTL-M3933 qualification with full 0 Hz ~ 18 GHz frequency coverage and 6dB attenuation. Power rating is not specified. This part is suitable for military-grade system requirements.

For Attenuation Tolerance Applications:

M3933/16-23N and M3933/16-23S provide 6.5dB attenuation (0.5dB variance from AT-106V specification) across the full 0 Hz ~ 18 GHz range with 2W power handling. These parts are applicable only where 6.5dB attenuation is acceptable within system design margins.
