Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ATS-2M2F-03DB5W are identified based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• Attenuation Value: 3dB (exact match required)
• Package / Case: N-Type In-Line Module (connector type and form factor)
• Impedance: 50 Ohms (electrical characteristic)

Secondary Compatibility Factors:

• Frequency Range: Minimum coverage of 0 Hz ~ 6 GHz operational band
• Power Rating: Minimum 5W capability

Substitute parts may exceed the original specifications in frequency range and power rating without affecting compatibility, as these represent enhanced performance margins. The attenuation value, impedance, and connector type are non-negotiable parameters for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

768A-3 (L3 Narda-MITEQ): This substitute provides identical 3dB attenuation in an N-Type in-line module configuration. The part is currently in active production status, ensuring long-term availability. The 768A-3 exceeds the original specification with extended frequency coverage to 11 GHz and increased power handling to 20W. Both parts share identical ECCN and HTSUS classifications. Selection of this substitute is appropriate for applications requiring enhanced performance margins or extended frequency operation within the same mechanical and electrical interface.

53AS105-K03N3 (Rosenberger): This substitute provides parametric equivalence to the ATS-2M2F-03DB5W with matching 3dB attenuation, 50 Ohm impedance, and 5W power rating in an N-Type in-line module. The part is in active production status. The 53AS105-K03N3 extends frequency coverage to 10 GHz and carries RoHS Compliance certification. This substitute maintains electrical and mechanical compatibility while offering improved regulatory compliance status and extended frequency range. Selection of this substitute is appropriate for applications requiring direct parameter matching with enhanced environmental compliance.

Frequently Asked Questions (FAQ)

Q: Can the 768A-3 be used as a direct replacement for the ATS-2M2F-03DB5W?

A: The 768A-3 provides functional substitution based on matching attenuation value (3dB) and N-Type in-line module package. However, impedance specification is not provided for the 768A-3. Verification of 50 Ohm impedance compatibility with your system is required before implementation. The extended frequency range (0 Hz ~ 11 GHz) and increased power rating (20W) represent performance enhancements over the original specification.

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

A: The 53AS105-K03N3 provides parametric equivalence with identical impedance (50 Ohms) and power rating (5W) specifications. The 768A-3 offers enhanced performance with higher power handling (20W) and extended frequency coverage (11 GHz) but does not specify impedance. For applications requiring exact parameter matching, the 53AS105-K03N3 is the more precise equivalent.

Q: Are both substitute parts compatible with existing N-Type connectors?

A: Both substitute parts utilize N-Type in-line module configuration, matching the original ATS-2M2F-03DB5W connector interface. Mechanical and electrical compatibility with existing N-Type connector systems is maintained.

Q: What is the significance of the product status difference?

A: The ATS-2M2F-03DB5W is classified as obsolete, indicating discontinued production. Both substitute parts (768A-3 and 53AS105-K03N3) are in active production status, ensuring continued availability for procurement and long-term supply chain reliability.

Q: Do the substitute parts have different regulatory compliance requirements?

A: All three parts share identical ECCN (EAR99) and HTSUS (8533.21.0090) classifications. The 53AS105-K03N3 carries additional RoHS Compliance certification. No regulatory barriers exist for substitution based on provided compliance data.
