ATS2012-0DB-T1 Equivalent & Substitute Parts

Part Overview

The ATS2012-0DB-T1 is a high-frequency chip attenuator manufactured by Susumu, designed for RF applications requiring 0 dB attenuation across a broad frequency spectrum. This component operates from 0 Hz to 30 GHz with 50-ohm impedance and 100 mW 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 when equivalent electrical specifications and mechanical compatibility are maintained across the same package form factor and core performance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ATS2012-0DB-T1 is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Attenuation Value: 0 dB (exact match required)
• Impedance: 50 Ohms (exact match required)
• Power Rating: 100 mW (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• RoHS Status: ROHS3 Compliant (compliance requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Secondary Consideration:

• Frequency Range: Substitutes must support the operating frequency requirements of the application. Parts with equal or greater frequency capability are functionally equivalent within their specified range.

All identified substitute parts meet these criteria. Frequency range variations among substitutes reflect different upper-frequency limits while maintaining full compatibility within their respective operational bands.

Parameter Comparison

Engineering Selection Recommendations

ATS2012-0DB-T05 (Susumu)

This part is a direct parametric equivalent to the ATS2012-0DB-T1, sharing identical electrical specifications and frequency range. Both components are manufactured by Susumu within the same ATS series. Selection between these two parts is based on packaging tape configuration and inventory availability. Both maintain Active product status and full RoHS3 compliance.

PAT1220-C-0DB-T5 (Susumu)

This substitute operates within a reduced frequency range of 0 Hz to 10 GHz compared to the primary part's 30 GHz capability. All other electrical parameters and mechanical specifications remain equivalent. This part is suitable for applications operating exclusively within the 0 to 10 GHz band. Product status is Active with full RoHS3 compliance.

TFA20C00DBER (Ohmite)

This substitute from Ohmite operates within a frequency range of 0 Hz to 20 GHz, providing intermediate frequency coverage between the PAT1220-C-0DB-T5 and the primary ATS2012-0DB-T1. All electrical parameters and mechanical specifications are equivalent. Product status is Active with full RoHS3 compliance. This part represents cross-manufacturer substitution while maintaining all core performance criteria.

Frequently Asked Questions (FAQ)

Q: Can ATS2012-0DB-T05 be used as a direct replacement for ATS2012-0DB-T1?

A: Yes. Both parts share identical attenuation value, frequency range, impedance, power rating, package form factor, and compliance certifications. The difference lies in tape packaging configuration. Electrical and mechanical compatibility is complete.

Q: What is the frequency limitation when using PAT1220-C-0DB-T5?

A: The PAT1220-C-0DB-T5 operates from 0 Hz to 10 GHz. Applications requiring operation above 10 GHz must use either the ATS2012-0DB-T1, ATS2012-0DB-T05, or TFA20C00DBER.

Q: Is TFA20C00DBER from a different manufacturer compatible with the ATS2012-0DB-T1?

A: Yes. Despite different manufacturers (Ohmite versus Susumu), the TFA20C00DBER meets all electrical and mechanical substitution criteria. It operates from 0 Hz to 20 GHz with identical impedance, power rating, and package specifications. Cross-manufacturer substitution is valid based on parameter equivalence.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 Compliant status with Moisture Sensitivity Level 1 (Unlimited), matching the primary part's compliance profile.

Q: What determines whether a part can substitute for the ATS2012-0DB-T1?

A: Substitution requires exact matching of attenuation value (0 dB), impedance (50 Ohms), power rating (100 mW), package form factor (0805 / 2012 Metric), and compliance certifications (ROHS3, MSL 1). Frequency range must meet or exceed the application requirement. All identified substitutes satisfy these criteria within their specified frequency bands.

Q: Can PAT1220-C-0DB-T5 be used in a 30 GHz application?

A: No. The PAT1220-C-0DB-T5 is specified only to 10 GHz. Applications requiring 30 GHz operation must use ATS2012-0DB-T1, ATS2012-0DB-T05, or TFA20C00DBER.
