M3933/16-06S RF Attenuator Equivalent & Substitute Parts

Part Overview

The M3933/16-06S is an RF attenuator module manufactured by Amphenol SV Microwave, currently in Active product status. This component provides 2dB attenuation across a frequency range of 0 Hz to 18 GHz with 50-ohm impedance and 2-watt power handling capability in an SMA in-line module configuration. Alternative models may be required for supply chain continuity, procurement optimization, or when original stock becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of RF attenuator modules is determined by strict equivalence of the following parameters: attenuation value (2dB), frequency range (0 Hz ~ 18 GHz), impedance (50 Ohms), power rating (2W), and package type (SMA In-Line Module). Parts meeting all these specifications are electrically and mechanically interchangeable. Manufacturer variation and product status are secondary considerations that do not affect electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The M3933/16-06S maintains Active product status with ROHS3 compliance, ensuring continued supplier support and long-term availability. The AT-102V alternative meets identical electrical and mechanical specifications but carries Last Time Buy status, indicating limited future availability. Selection between these parts should be based on supply chain requirements and long-term product roadmap considerations. Both components satisfy identical RF attenuation, frequency response, impedance, and power handling specifications required for direct electrical substitution.

Frequently Asked Questions (FAQ)

What determines if AT-102V can substitute for M3933/16-06S? Electrical and mechanical interchangeability is confirmed when attenuation value, frequency range, impedance, power rating, and SMA package type are identical. Both parts meet these criteria.

Are there compatibility concerns between the two part numbers? No compatibility concerns exist for electrical applications. Both components provide 2dB attenuation, operate across 0 Hz to 18 GHz, maintain 50-ohm impedance, and handle 2-watt power in SMA in-line module form factor.

What is the significance of different product status designations? M3933/16-06S (Active status) has ongoing production and supplier support. AT-102V (Last Time Buy status) indicates this part will no longer be manufactured after a specified date. Selection should account for procurement timeline and inventory planning.

Do RoHS compliance differences affect substitution? Both parts are RoHS compliant (M3933/16-06S is ROHS3 compliant; AT-102V is RoHS compliant). This does not prevent substitution but reflects different compliance certifications from each manufacturer.
