M3933/16-06N RF Attenuator 2dB 50 Ohm SMA In-Line Module

Part Overview

The M3933/16-06N is an RF attenuator designed for microwave signal conditioning applications. This 2dB fixed-loss module operates across the DC to 18 GHz frequency range with 50 Ohm impedance and 2W power handling capability in an SMA in-line configuration. The part is currently in active production status. Alternative part sourcing becomes necessary due to supply availability, inventory levels, or procurement lead time requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M3933/16-06N is determined by exact matching of the following critical electrical and mechanical parameters:

• Attenuation Value: 2dB (fixed, no tolerance variation)
• Frequency Range: 0 Hz ~ 18 GHz minimum operational bandwidth
• Impedance: 50 Ohms (standard RF impedance)
• Power Rating: 2W minimum handling capability
• Package / Case: SMA In-Line Module (connector and form factor)

The AT-102V manufactured by Hirose Electric Co Ltd satisfies all substitution criteria with identical electrical specifications and mechanical configuration.

Engineering Selection Recommendations

Primary Selection: M3933/16-06N is the preferred choice for new designs and ongoing procurement due to active production status and ROHS3 compliance certification.

Alternative Selection: AT-102V serves as a functional equivalent for existing applications requiring immediate component sourcing. However, this part carries Last Time Buy status, indicating limited production window and finite inventory availability. The AT-102V maintains full RoHS compliance and identical electrical-mechanical parameters but should not be selected for applications with extended production timelines.

Frequently Asked Questions (FAQ)

Q: Can AT-102V be used as a direct replacement for M3933/16-06N in existing circuits?

A: Yes. Both parts meet identical attenuation (2dB), frequency range (0 Hz ~ 18 GHz), impedance (50 Ohms), power rating (2W), and SMA in-line package specifications. No circuit redesign or board layout modification is required.

Q: What is the difference in RoHS compliance between these parts?

A: M3933/16-06N carries ROHS3 certification, representing compliance with the latest RoHS 3 directive including additional restricted substance limitations. AT-102V is RoHS compliant, meeting the baseline RoHS standard. Both are suitable for applications requiring RoHS compliance; ROHS3 certification represents an enhanced compliance level.

Q: Does the Last Time Buy status of AT-102V affect its reliability?

A: Last Time Buy status indicates that the manufacturer has announced discontinuation of the product line. This is a production and availability designation, not a reliability indicator. The part's electrical performance and quality remain unchanged. AT-102V is suitable for field replacement and repair applications but should not be selected for high-volume or long-term production programs.

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

A: The main part (M3933/16-06N) ships in Bag packaging, while the substitute (AT-102V) is supplied in Bulk packaging. Both contain SMA in-line module components. Packaging format does not affect functional compatibility; selection between packaging types depends on procurement and assembly logistics requirements.

Q: Can AT-102V be used in new design applications?

A: AT-102V is functionally equivalent and may be used during the design phase; however, production sourcing should transition to M3933/16-06N or alternative sources due to Last Time Buy status limiting long-term availability.
