ATS2012-8DB-T1 Equivalent & Substitute Parts

Part Overview

The ATS2012-8DB-T1 is a high-frequency chip attenuator manufactured by Susumu, classified as an RF attenuator with 8dB attenuation across a 0 Hz to 30 GHz frequency range. This component operates at 50 Ohms impedance with 100mW power handling capability in a 0805 (2012 Metric) surface-mount package. The part maintains Active product status and carries ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified to support procurement flexibility, inventory optimization, and supply chain continuity when the primary part becomes unavailable or when design requirements permit operation within alternative frequency specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RF attenuators is determined by matching critical electrical and mechanical parameters: attenuation value, impedance, power rating, package form factor, and frequency range capability. All substitute parts listed maintain identical attenuation (8dB), impedance (50 Ohms), power handling (100mW), and package specification (0805 / 2012 Metric) as the primary part.

Frequency range variations exist among substitutes and represent the primary technical distinction. The ATS2012-8DB-T1 operates across 0 Hz to 30 GHz, establishing the maximum frequency capability. Substitute parts with equal or greater frequency range capability are fully interchangeable. Substitute parts with reduced frequency range (0 Hz to 10 GHz or 0 Hz to 20 GHz) are suitable only for applications operating within their specified frequency limits.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and Active product status, ensuring regulatory and environmental consistency with the primary part.

Parameter Comparison

Engineering Selection Recommendations

ATS2012-8DB-T1 (Primary Part): Select this part for applications requiring full 30 GHz frequency coverage. This part provides the broadest frequency capability among the three options and is suitable for millimeter-wave and high-frequency RF systems operating across the complete 0 Hz to 30 GHz spectrum.

TFA20C08DBER (Ohmite): This substitute provides 20 GHz maximum frequency capability, suitable for applications operating within the 0 Hz to 20 GHz range. This part offers intermediate frequency coverage and represents a viable alternative when the full 30 GHz range is not required. Ohmite manufacturing provides an alternative supplier source while maintaining identical electrical specifications and package form factor.

PAT1220-C-8DB-T5 (Susumu): This substitute provides 10 GHz maximum frequency capability, suitable for applications operating within the 0 Hz to 10 GHz range. This part is appropriate for lower-frequency RF and microwave applications that do not require extended frequency coverage. Susumu manufacturing maintains supplier continuity with the primary part.

All three parts maintain identical compliance certifications, power handling, impedance, and package specifications. Selection between parts depends solely on application frequency requirements and supplier availability.

Frequently Asked Questions (FAQ)

Q: Can PAT1220-C-8DB-T5 be used in place of ATS2012-8DB-T1?

A: PAT1220-C-8DB-T5 is suitable only for applications operating within 0 Hz to 10 GHz. If your application requires operation above 10 GHz, this substitute is not appropriate. For applications limited to 10 GHz or below, this part is electrically and mechanically compatible.

Q: Can TFA20C08DBER be used in place of ATS2012-8DB-T1?

A: TFA20C08DBER is suitable for applications operating within 0 Hz to 20 GHz. If your application requires operation above 20 GHz, this substitute is not appropriate. For applications limited to 20 GHz or below, this part is electrically and mechanically compatible.

Q: Are all three parts physically identical?

A: All three parts use the 0805 (2012 Metric) surface-mount package and are physically identical in form factor, footprint, and mounting requirements. They are directly interchangeable from a PCB layout and assembly perspective.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and maintain Active product status. Regulatory and environmental compliance is consistent across all options.

Q: What is the primary difference between these parts?

A: The primary difference is maximum frequency capability. ATS2012-8DB-T1 operates to 30 GHz, TFA20C08DBER to 20 GHz, and PAT1220-C-8DB-T5 to 10 GHz. All other electrical parameters (attenuation, impedance, power rating) and physical specifications are identical.

Q: Can I use a lower-frequency part in a higher-frequency application?

A: No. A part specified for 10 GHz maximum frequency cannot be used in applications requiring operation above 10 GHz. Frequency range specifications represent the upper operating limit of the component.

Q: Are there any packaging differences between these parts?

A: All three parts are supplied in Tape & Reel (TR) packaging format. Packaging format is identical across all options.
