Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RF attenuators is determined by the following critical parameters:

• Attenuation Value: Must match exactly at 6dB
• Impedance: Must match exactly at 50 Ohms
• Package Type: Must be SMA In-Line Module for mechanical and electrical compatibility
• Power Rating: Must meet or exceed 10W requirement
• Frequency Range: Must encompass or exceed the 0 Hz ~ 8 GHz operating band

The substitute part 5906_SMA-50-010/19-_NE satisfies all mandatory substitution criteria. Its extended frequency range (0 Hz ~ 18 GHz) provides broader operational capability while maintaining identical attenuation, impedance, power handling, and package specifications.

Parameter Comparison

Engineering Selection Recommendations

The 5906_SMA-50-010/19-_NE from Huber+Suhner is a direct functional substitute for the AT-1006(40). Selection rationale is based on:

• Compliance: Both parts meet RoHS requirements; the substitute carries ROHS3 certification, representing current regulatory compliance standards
• Product Status: The substitute maintains Active status, ensuring ongoing availability and supply chain stability
• Electrical Equivalence: Identical attenuation (6dB), impedance (50 Ohms), and power rating (10W) guarantee electrical interchangeability
• Mechanical Compatibility: Both use SMA In-Line Module packaging, enabling direct mechanical substitution
• Performance Enhancement: The extended frequency range (18 GHz vs. 8 GHz) provides operational margin for applications within the original 8 GHz specification

Frequently Asked Questions (FAQ)

Q: Can the 5906_SMA-50-010/19-_NE be used as a direct replacement for AT-1006(40)?

A: Yes. Both parts provide identical 6dB attenuation at 50 Ohm impedance with 10W power handling in SMA In-Line Module configuration. The substitute's extended frequency range does not affect compatibility within the original 0-8 GHz operating band.

Q: What is the significance of the extended frequency range in the substitute part?

A: The 5906_SMA-50-010/19-_NE operates to 18 GHz versus the AT-1006(40)'s 8 GHz limit. This provides operational margin and future flexibility for applications that may require higher frequency capability, while maintaining full compatibility at the original 8 GHz specification.

Q: Are there mechanical differences between these SMA In-Line Module packages?

A: Both parts use identical SMA In-Line Module packaging. No mechanical modifications or adapter components are required for substitution.

Q: How do the RoHS certifications compare?

A: The AT-1006(40) carries RoHS Compliant status, while the 5906_SMA-50-010/19-_NE carries ROHS3 Compliant status. ROHS3 represents the current regulatory standard and is fully backward compatible with RoHS requirements.

Q: What is the inventory status for the substitute part?

A: The 5906_SMA-50-010/19-_NE has 995 pieces in stock with Active product status, ensuring reliable supply availability compared to the AT-1006(40)'s Last Time Buy status.
