ATS2012-5DB-T1 Equivalent & Substitute Parts

Part Overview

The ATS2012-5DB-T1 is a high-frequency chip attenuator manufactured by Susumu, designed for RF applications requiring 5dB 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 with MSL 1 (unlimited moisture sensitivity level).

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the critical performance parameters. Alternative sources and packaging variants may be required due to inventory availability, supply chain considerations, or specific application frequency requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RF attenuators is determined by matching the following critical parameters:

Primary Matching Criteria:

• Attenuation Value: 5dB (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: Substitutes must support the application frequency requirements. Parts with equal or greater frequency capability are acceptable for applications operating within their specified range.

All identified substitute parts maintain identical attenuation, impedance, power handling, and package specifications. Frequency range variations reflect different design implementations and manufacturing sources while preserving core RF performance characteristics within their respective operational bands.

Engineering Selection Recommendations

ATS2012-5DB-T05 (Susumu)

This part is a direct parametric equivalent to the ATS2012-5DB-T1, manufactured by the same supplier. Both components share identical electrical specifications and frequency capability (0 Hz ~ 30 GHz). Selection between these two Susumu variants is based on packaging tape configuration and inventory availability. Both maintain Active product status and full ROHS3 compliance.

TFA20C05DBER (Ohmite)

This alternative source component provides equivalent attenuation, impedance, and power handling in the same 0805 package format. The frequency range extends to 20 GHz, which is suitable for applications operating below this threshold. This part is manufactured by Ohmite and carries identical RoHS and MSL certifications. Selection is appropriate when Ohmite supply chain access is preferred or when application frequency requirements do not exceed 20 GHz.

PAT1220-C-5DB-T5 (Susumu)

This Susumu variant maintains the same attenuation, impedance, and power specifications in the 0805 package. The frequency range is limited to 10 GHz, restricting its use to applications operating within this bandwidth. This part is suitable only for lower-frequency RF applications and should not be selected for systems requiring operation above 10 GHz.

All substitute parts carry Active product status and maintain full regulatory compliance (ROHS3, REACH Unaffected, EAR99 classification).

Frequently Asked Questions (FAQ)

Q: Can ATS2012-5DB-T05 be used as a direct replacement for ATS2012-5DB-T1?

A: Yes. Both parts are manufactured by Susumu and share identical electrical specifications: 5dB attenuation, 0 Hz ~ 30 GHz frequency range, 50-ohm impedance, 100mW power rating, and 0805 package format. The difference lies in tape packaging configuration. Both maintain Active status and ROHS3 compliance.

Q: What is the frequency limitation of PAT1220-C-5DB-T5?

A: The PAT1220-C-5DB-T5 operates from 0 Hz to 10 GHz. This part is suitable only for applications with maximum operating frequencies at or below 10 GHz. For systems requiring operation above 10 GHz, use ATS2012-5DB-T1, ATS2012-5DB-T05, or TFA20C05DBER.

Q: Is the TFA20C05DBER from Ohmite compatible with the ATS2012-5DB-T1 footprint?

A: Yes. The TFA20C05DBER is packaged in the 0805 (2012 metric) format, identical to the ATS2012-5DB-T1. Both components share the same mechanical footprint and can be used interchangeably from a PCB layout perspective. Electrical specifications (5dB attenuation, 50-ohm impedance, 100mW power) are also equivalent.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching attenuation value (5dB), impedance (50 ohms), power rating (100mW), and package format (0805 metric). Frequency range must meet or exceed the application requirement. All substitutes must maintain ROHS3 compliance and MSL 1 rating.

Q: Can I use TFA20C05DBER in a 30 GHz application?

A: No. The TFA20C05DBER is specified for operation up to 20 GHz. For applications requiring 30 GHz operation, use ATS2012-5DB-T1 or ATS2012-5DB-T05, both rated to 30 GHz.

Q: Are all substitute parts in Active product status?

A: Yes. All listed substitute parts (ATS2012-5DB-T05, PAT1220-C-5DB-T5, and TFA20C05DBER) maintain Active product status, indicating ongoing manufacturing and availability.

Q: What is the moisture sensitivity level for all these parts?

A: All parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. Standard component storage practices apply.
