Substitute Part Grouping Explanation

Substitution eligibility for RF attenuators is determined by strict equivalence across core electrical and mechanical parameters. The AT-1020(40) substitutes are qualified based on the following criteria:

Critical Parameters for Substitution:

• Attenuation Value: 20dB (exact match required)
• Impedance: 50 Ohms (exact match required)
• Power Rating: 10W (exact match required)
• Package/Connector Type: SMA In-Line Module (exact match required)

Frequency Range Consideration: Substitute parts may operate across equal or extended frequency ranges. The AT-1020(40) operates 0 Hz ~ 8 GHz. Substitutes with extended frequency capability (0 Hz ~ 18 GHz) remain functionally equivalent for applications within the 0-8 GHz band.

Compliance Consideration: Both RoHS Compliant and ROHS3 Compliant parts meet regulatory requirements and are interchangeable from a compliance perspective.

Parameter Comparison

Engineering Selection Recommendations

5920_SMA-50-010/19-_NE (Huber+Suhner, Inc.): This substitute provides extended frequency coverage to 18 GHz while maintaining all critical electrical parameters. The part is in Active product status with current inventory availability (778 Pcs). ROHS3 compliance exceeds the original RoHS requirement. This option is suitable for applications requiring future frequency headroom within the same mechanical and electrical envelope.

R415320000 (Radiall USA, Inc.): This substitute matches the AT-1020(40) across all critical parameters including identical frequency range (0 Hz ~ 8 GHz). The part is in Active product status with strong inventory availability (716 Pcs). ROHS3 compliance meets regulatory requirements. This option provides direct functional equivalence with no frequency derating considerations.

Both substitutes are available in bulk packaging and carry identical ECCN and HTSUS classifications where applicable, supporting seamless integration into existing supply chains and regulatory documentation.

Frequently Asked Questions (FAQ)

Q: Can the 5920_SMA-50-010/19-_NE be used as a direct replacement for AT-1020(40)? A: Yes. The extended frequency range (0 Hz ~ 18 GHz) does not compromise performance within the original 0-8 GHz operating band. All electrical parameters—attenuation, impedance, and power rating—are identical. The SMA In-Line Module package ensures mechanical compatibility.

Q: What is the difference between RoHS and ROHS3 compliance? A: Both certifications indicate lead-free and restricted substance compliance. ROHS3 represents a more recent compliance standard. Both are acceptable for applications requiring RoHS compliance.

Q: Are there any frequency limitations when substituting with the Huber+Suhner part? A: No. The Huber+Suhner 5920_SMA-50-010/19-_NE operates across 0 Hz ~ 18 GHz, which encompasses the original 0-8 GHz specification. Applications limited to 8 GHz operation will function identically to the original part.

Q: Which substitute should be selected for new designs? A: Selection depends on application requirements. For applications requiring only 0-8 GHz operation, either substitute is suitable. For systems with potential future frequency expansion or multi-band applications, the Huber+Suhner part with 18 GHz capability provides additional design flexibility.

Q: Are the SMA connectors on all three parts identical? A: Yes. All three parts use SMA In-Line Module packaging, ensuring mechanical and electrical connector compatibility across the main part and both substitutes.
