ATS2012-4DB-T1 Equivalent & Substitute Parts

Part Overview

The ATS2012-4DB-T1 is a high frequency chip attenuator manufactured by Susumu, designed for RF applications requiring fixed 4dB 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 for design flexibility, inventory optimization, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ATS2012-4DB-T1 is determined by the following critical parameters:

Primary Matching Criteria:

• Attenuation Value: 4dB (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 (compliance requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (handling requirement)

Secondary Consideration:

• Frequency Range: The main part operates 0 Hz ~ 30 GHz. Substitute parts with equal or greater frequency coverage are functionally equivalent. Parts with reduced frequency range (0 Hz ~ 10 GHz or 0 Hz ~ 20 GHz) remain substitutable for applications operating within their specified limits.

All identified substitute parts meet the primary matching criteria. Frequency range variations are noted in the parameter comparison table to enable application-specific selection.

Frequently Asked Questions (FAQ)

Q: Can ATS2012-4DB-T05 be used as a direct replacement for ATS2012-4DB-T1?

A: Yes. The ATS2012-4DB-T05 is a parametric equivalent with identical attenuation (4dB), frequency range (0 Hz ~ 30 GHz), impedance (50 Ohms), power rating (100mW), package (0805), and compliance certifications. Both parts are manufactured by Susumu and carry Active product status.

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

A: All three substitutes match the primary electrical specifications (4dB, 50 Ohm, 100mW, 0805 package). The key difference is frequency range: ATS2012-4DB-T05 covers 0 Hz ~ 30 GHz (matching the main part), TFA20C04DBER covers 0 Hz ~ 20 GHz, and PAT1220-C-4DB-T5 covers 0 Hz ~ 10 GHz. Selection depends on the application's maximum operating frequency requirement.

Q: Can I use PAT1220-C-4DB-T5 or TFA20C04DBER if my application operates above their specified frequency ranges?

A: No. Component performance is specified only within the stated frequency range. Using a part outside its specified frequency range may result in performance degradation or failure. Select a substitute part whose frequency range encompasses your application's operating band.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification, matching the main part's regulatory status.

Q: What is the Moisture Sensitivity Level (MSL) for all these parts?

A: All parts, including the main part and all substitutes, carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which substitute part has the best inventory availability?

A: PAT1220-C-4DB-T5 has the highest inventory with 19322 Pcs in stock, followed by TFA20C04DBER with 5305 Pcs, and ATS2012-4DB-T05 with 2687 Pcs. Inventory levels support supply chain planning and lead time optimization.

Q: Can I mix different substitute parts in the same design?

A: Yes, provided all parts operate within the frequency range requirements of your specific application. All substitutes share identical attenuation, impedance, power rating, and package specifications, ensuring functional compatibility within their respective frequency bands.

Q: Is there a performance difference between Susumu and Ohmite parts?

A: Both manufacturers' parts meet the specified electrical parameters (4dB attenuation, 50 Ohm impedance, 100mW power) and compliance requirements. Selection between manufacturers is based on frequency range requirements, inventory availability, and supply chain preferences.
