ATS2012-3DB-T1 Equivalent & Substitute Parts
Part Overview
The ATS2012-3DB-T1 is a high-frequency chip attenuator manufactured by Susumu, designed for RF applications requiring 3dB 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 full RoHS3 compliance with unlimited moisture sensitivity rating. Substitute parts are identified to address inventory availability, packaging format preferences, or frequency range optimization for specific application requirements.

Substitute Part Grouping Explanation
Substitution eligibility for the ATS2012-3DB-T1 is determined by matching the following critical parameters: attenuation value (3dB), impedance (50 Ohms), power rating (100mW), package format (0805/2012 Metric), RoHS3 compliance, and MSL rating (1). Frequency range represents a secondary consideration; parts with equal or greater frequency capability are functionally equivalent for applications operating within the lower frequency band.
The identified substitute parts maintain all primary electrical and mechanical specifications. Packaging format variations (Tape & Reel versus Cut Tape & Digi-Reel) do not affect electrical performance and reflect distribution channel differences. All substitute parts carry Active product status and identical compliance certifications.

Engineering Selection Recommendations
ATS2012-3DB-T05 (Susumu): This part is a direct parametric equivalent to the ATS2012-3DB-T1, matching all electrical specifications and frequency range (0 Hz ~ 30 GHz). Both components are manufactured by Susumu and packaged in Tape & Reel format. Selection of this substitute is appropriate when inventory of the primary part is unavailable. Current inventory availability is 3057 units.
TFA20C03DBER (Ohmite): This substitute maintains all critical electrical parameters (3dB attenuation, 50-ohm impedance, 100mW power rating) and operates across 0 Hz ~ 20 GHz. The reduced frequency upper limit (20 GHz versus 30 GHz) restricts this part to applications operating below 20 GHz. This part is suitable for mid-frequency RF applications and offers the highest current inventory level at 5129 units.
PAT1220-C-3DB-T5 (Susumu): This substitute matches all electrical specifications but operates across a narrower frequency range (0 Hz ~ 10 GHz). The reduced frequency capability limits this part to low-frequency RF and microwave applications. Packaging is provided in Cut Tape & Digi-Reel format rather than standard Tape & Reel. Current inventory is 2693 units.
All substitute parts carry Active product status, ROHS3 compliance, and REACH Unaffected designation, ensuring regulatory and environmental compatibility with the primary part.
Frequently Asked Questions (FAQ)
Q: Can ATS2012-3DB-T05 be used as a direct replacement for ATS2012-3DB-T1?
A: Yes. Both parts are manufactured by Susumu and share identical electrical specifications: 3dB attenuation, 50-ohm impedance, 100mW power rating, 0 Hz ~ 30 GHz frequency range, and 0805 (2012 Metric) package. The only difference is packaging format (both Tape & Reel), making this a direct parametric equivalent.
Q: What is the frequency limitation of the PAT1220-C-3DB-T5 substitute?
A: The PAT1220-C-3DB-T5 operates across 0 Hz ~ 10 GHz, compared to the primary part's 0 Hz ~ 30 GHz range. This part is suitable only for applications operating below 10 GHz. Applications requiring operation above 10 GHz must use the ATS2012-3DB-T1, ATS2012-3DB-T05, or TFA20C03DBER.
Q: Is the TFA20C03DBER from Ohmite compatible with the ATS2012-3DB-T1?
A: The TFA20C03DBER is electrically compatible for applications operating below 20 GHz. It matches the 3dB attenuation, 50-ohm impedance, 100mW power rating, and 0805 package. However, its frequency range (0 Hz ~ 20 GHz) is narrower than the primary part (0 Hz ~ 30 GHz). Applications requiring operation above 20 GHz must use the ATS2012-3DB-T1 or ATS2012-3DB-T05.
Q: Does packaging format affect electrical performance?
A: No. Packaging format differences (Tape & Reel versus Cut Tape & Digi-Reel) reflect distribution and handling methods only. Electrical performance and component specifications remain identical. Selection between packaging formats depends on assembly process requirements and inventory management practices.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All identified substitute parts (ATS2012-3DB-T05, TFA20C03DBER, and PAT1220-C-3DB-T5) carry ROHS3 compliance and REACH Unaffected designation, matching the primary part's regulatory status.
Q: What is the moisture sensitivity rating for all parts in this group?
A: All parts, including the primary ATS2012-3DB-T1 and all substitutes, carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
