Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AT-1110(40) are qualified based on the following critical parameters that determine functional equivalence:

• Attenuation Value: 10dB (exact match required)
• Impedance: 50 Ohms (exact match required)
• Power Rating: 10W (exact match required)
• Package Type: SMA In-Line Module (exact match required)
• Frequency Range: Minimum coverage of 0 Hz ~ 8 GHz

Two substitute parts meet these criteria. The Huber+Suhner 5910_SMA-50-010/19-_NE provides extended frequency coverage to 18 GHz while maintaining all core electrical parameters. The Radiall R415310000 provides identical frequency range and electrical specifications to the original part.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are qualified alternatives to the AT-1110(40) based on matching electrical and mechanical parameters.

The Radiall R415310000 provides direct specification equivalence with identical frequency range (0 Hz ~ 8 GHz) and is currently in Active product status with ROHS3 compliance certification.

The Huber+Suhner 5910_SMA-50-010/19-_NE maintains all core electrical parameters while offering extended frequency coverage to 18 GHz. This part is also in Active product status with ROHS3 compliance certification. The extended frequency range provides additional operational margin for applications requiring higher frequency performance.

Both parts carry ECCN EAR99 classification and are suitable for direct substitution in applications currently using the AT-1110(40).

Frequently Asked Questions (FAQ)

Q: Can the Huber+Suhner 5910_SMA-50-010/19-_NE be used as a direct replacement for the AT-1110(40)?

A: Yes. Both parts share identical attenuation value (10dB), impedance (50 Ohms), power rating (10W), and SMA in-line module package. The Huber+Suhner part provides extended frequency coverage to 18 GHz, which exceeds the original part's 8 GHz specification.

Q: What is the difference between the two substitute parts?

A: The primary difference is frequency range. The Radiall R415310000 matches the original AT-1110(40) frequency specification of 0 Hz ~ 8 GHz. The Huber+Suhner 5910_SMA-50-010/19-_NE extends to 18 GHz. All other electrical and mechanical parameters are identical.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the Radiall R415310000 and Huber+Suhner 5910_SMA-50-010/19-_NE carry ROHS3 compliance certification, meeting current environmental standards.

Q: Can I use these parts interchangeably in my existing designs?

A: Yes, provided your application operates within the specified frequency range of the selected substitute. Both parts maintain the same SMA connector interface and mechanical form factor as the original AT-1110(40).

Q: Why is the AT-1110(40) marked as Last Time Buy?

A: Last Time Buy status indicates this part is being discontinued by the manufacturer. Identifying and qualifying substitute parts ensures continuity for ongoing production and system support.
