Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AT-1106(40) are identified based on the following critical parameters that must remain constant or compatible:

• Attenuation Value: 6dB (exact match required)
• Impedance: 50 Ohms (exact match required)
• Power Rating: 10W (exact match required)
• Package / Case: SMA In-Line Module (exact match required)
• Frequency Range: Must encompass or exceed the original 0 Hz ~ 8 GHz specification

The substitute part 5906_SMA-50-010/19-_NE from Huber+Suhner, Inc. meets all critical substitution criteria with identical attenuation, impedance, power rating, and package type. The extended frequency range (0 Hz ~ 18 GHz) provides additional operational bandwidth beyond the original specification, maintaining full backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 5906_SMA-50-010/19-_NE is a direct functional substitute for the AT-1106(40). Both parts maintain identical electrical specifications for attenuation (6dB), impedance (50 Ohms), and power handling (10W), with matching SMA in-line module packaging. The substitute part offers extended frequency coverage (18 GHz vs. 8 GHz), providing enhanced operational range without compromising performance within the original specification band.

The substitute part carries ROHS3 compliance, meeting current regulatory requirements. With active product status, the 5906_SMA-50-010/19-_NE ensures ongoing availability and supply chain stability compared to the Last Time Buy status of the original part.

Frequently Asked Questions (FAQ)

Q: Can the 5906_SMA-50-010/19-_NE replace the AT-1106(40) in existing designs?

A: Yes. Both parts share identical attenuation (6dB), impedance (50 Ohms), power rating (10W), and SMA in-line module packaging. The substitute part's extended frequency range (18 GHz) is fully compatible with applications designed for 0 Hz ~ 8 GHz operation.

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

A: The 5906_SMA-50-010/19-_NE operates across 0 Hz ~ 18 GHz, exceeding the original 0 Hz ~ 8 GHz specification. This extended range provides additional operational bandwidth while maintaining identical performance within the original frequency band.

Q: Are there mechanical compatibility concerns between these parts?

A: No. Both parts use identical SMA in-line module packaging, ensuring direct mechanical and electrical compatibility in circuit board layouts and connector interfaces.

Q: Why is the original part classified as Last Time Buy?

A: Last Time Buy status indicates end-of-life designation by the manufacturer. The 5906_SMA-50-010/19-_NE, with active product status, provides a viable alternative for continued supply and future design iterations.

Q: What compliance differences exist between the two parts?

A: The AT-1106(40) is RoHS Compliant, while the 5906_SMA-50-010/19-_NE is ROHS3 Compliant. ROHS3 represents current regulatory compliance standards and is fully compatible with RoHS-compliant applications.
