ATS2012-1DB-T1 Equivalent & Substitute Parts

Part Overview

The ATS2012-1DB-T1 is a high-frequency chip attenuator manufactured by Susumu, designed for RF applications requiring 1dB attenuation across a broad frequency spectrum. This component operates from 0 Hz to 30 GHz with 50-ohm impedance and 100mW power handling capability in a compact 0805 (2012 Metric) surface-mount package. The part maintains Active product status and carries ROHS3 compliance certification. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ATS2012-1DB-T1 is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Attenuation Value: 1dB (exact match required)
• Impedance: 50 Ohms (exact match required)
• Power Rating: 100mW (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• Product Status: Active (exact match required)

Secondary Consideration:

• Frequency Range: Parts with frequency ranges equal to or exceeding the main part's 0 Hz ~ 30 GHz specification are acceptable substitutes. Parts with reduced frequency ranges (such as 0 Hz ~ 10 GHz or 0 Hz ~ 20 GHz) operate within narrower application windows but maintain full electrical compatibility within their specified frequency limits.

All identified substitute parts meet the primary criteria. Frequency range variations are noted in the parameter comparison table to enable informed selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

Full Parameter Match (Recommended for Direct Substitution):

The ATS2012-1DB-T05 provides identical electrical and mechanical specifications to the ATS2012-1DB-T1, including the full 0 Hz ~ 30 GHz frequency range. Both parts are manufactured by Susumu, carry Active product status, and maintain ROHS3 compliance with unlimited moisture sensitivity rating. This part is suitable for direct substitution without application constraints.

Frequency-Limited Substitutes (Application-Dependent):

The TFA20C01DBER (Ohmite, 0 Hz ~ 20 GHz) and PAT1220-C-1DB-T5 (Susumu, 0 Hz ~ 10 GHz) meet all primary electrical and mechanical criteria but operate within reduced frequency ranges. Both parts maintain Active status and full compliance certifications. Selection of these parts is appropriate when application frequency requirements fall within their specified operating ranges.

All substitute parts carry ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and Active product status, ensuring regulatory and supply chain consistency with the main part.

Frequently Asked Questions (FAQ)

Q: Can ATS2012-1DB-T05 be used as a direct replacement for ATS2012-1DB-T1?

A: Yes. The ATS2012-1DB-T05 matches all electrical and mechanical parameters of the ATS2012-1DB-T1, including attenuation value (1dB), frequency range (0 Hz ~ 30 GHz), impedance (50 Ohms), power rating (100mW), package type (0805 / 2012 Metric), and compliance certifications (ROHS3, MSL 1). Both parts are manufactured by Susumu and maintain Active product status.

Q: What is the difference between the ATS2012-1DB-T1 and TFA20C01DBER?

A: Both parts share identical attenuation (1dB), impedance (50 Ohms), power rating (100mW), package type (0805 / 2012 Metric), and compliance status (ROHS3, MSL 1). The primary difference is the frequency range: ATS2012-1DB-T1 operates from 0 Hz ~ 30 GHz, while TFA20C01DBER operates from 0 Hz ~ 20 GHz. The TFA20C01DBER is manufactured by Ohmite rather than Susumu. Selection depends on whether the application requires operation above 20 GHz.

Q: Is PAT1220-C-1DB-T5 suitable for all applications requiring the ATS2012-1DB-T1?

A: The PAT1220-C-1DB-T5 meets all primary electrical and mechanical specifications (1dB attenuation, 50-ohm impedance, 100mW power, 0805 package, ROHS3 compliance, MSL 1). However, its frequency range is limited to 0 Hz ~ 10 GHz compared to the ATS2012-1DB-T1's 0 Hz ~ 30 GHz range. This part is suitable only for applications operating within the 0 Hz ~ 10 GHz frequency band.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts (ATS2012-1DB-T05, PAT1220-C-1DB-T5, and TFA20C01DBER) are supplied in Tape & Reel (TR) packaging and use the 0805 (2012 Metric) surface-mount package format, matching the ATS2012-1DB-T1 package specification.

Q: Do all substitute parts carry the same compliance certifications?

A: Yes. All substitute parts carry ROHS3 compliance, maintain Moisture Sensitivity Level 1 (Unlimited), and hold Active product status. All parts are REACH Unaffected and classified under ECCN EAR99.
