Key Parameters

Substitute Part Grouping Explanation

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

• Attenuation Value: Must be 10dB (exact match required)
• Impedance: Must be 50 Ohms (exact match required)
• Package Type: Must be SMA In-Line Module (exact match required)
• Power Rating: Must be ≥10W (equal or greater acceptable)
• Frequency Range: Must cover the operating band; extended range acceptable

The identified substitute parts meet all mandatory matching criteria. The Huber+Suhner part extends the frequency range to 18 GHz, providing broader operational capability while maintaining all other specifications. The Radiall part provides an exact frequency range match with identical electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are qualified replacements based on parametric equivalence and compliance status:

Huber+Suhner 5910_SMA-50-010/19-_NE: This part is recommended for applications requiring extended frequency coverage beyond 8 GHz, up to 18 GHz. It maintains all electrical specifications of the original part while offering broader operational bandwidth. The part carries ROHS3 compliance certification and is in Active product status, ensuring long-term availability and supply chain stability.

Radiall R415310000: This part provides an exact electrical and frequency match to the original AT-1010(40). It is suitable for direct replacement in existing designs without frequency-related considerations. The part is in Active product status with ROHS3 compliance, providing equivalent long-term availability.

Both substitute parts are available in production quantities and carry identical ECCN and HTSUS classifications as the original part, simplifying regulatory and procurement documentation.

Frequently Asked Questions (FAQ)

Q: Can the Huber+Suhner part be used as a direct replacement in systems designed for the AT-1010(40)?

A: Yes. The Huber+Suhner 5910_SMA-50-010/19-_NE meets all mandatory electrical parameters (10dB attenuation, 50-ohm impedance, 10W power rating, SMA in-line package). The extended frequency range to 18 GHz does not create incompatibility; it provides additional operational capability. Physical form factor and connector type are identical.

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

A: The primary difference is frequency range. The Radiall R415310000 matches the original 0-8 GHz specification exactly, while the Huber+Suhner part extends to 18 GHz. Both maintain identical attenuation, impedance, power rating, and package specifications. Selection depends on whether extended frequency coverage is required for the application.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both substitute parts carry ROHS3 compliance certification, meeting current environmental and regulatory requirements. The original AT-1010(40) is RoHS Compliant. All three parts satisfy RoHS requirements for new designs and procurement.

Q: Why is the original AT-1010(40) in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing production. The identified substitute parts from Huber+Suhner and Radiall are in Active status, ensuring continued availability and supply chain support for equivalent functionality.

Q: Can these parts be used interchangeably in the same circuit board design?

A: Yes. All three parts share identical SMA in-line module packaging and electrical specifications (within the stated frequency ranges). No circuit board modifications or design changes are required for substitution.
