Engineering Selection Recommendations

Primary Substitute: T520B336M006ATE070

The T520B336M006ATE070 is the direct functional equivalent of the T520B336M006ASE070. This part maintains identical electrical specifications (33 µF, 6.3 V, 70 mOhm ESR) and mechanical dimensions (1411 package, 0.079" maximum seated height). The T520B336M006ATE070 is classified as active product status and carries ROHS3 compliance certification, addressing the RoHS non-compliance status of the obsolete main part. The primary difference is packaging format: Tape & Reel (TR) versus bulk. This substitute is suitable for production environments requiring automated component handling.

Secondary Substitute: T520T336M006ATE070

The T520T336M006ATE070 maintains all electrical specifications identical to the main part (33 µF, 6.3 V, 70 mOhm ESR) and operates within the same temperature range. This part differs in maximum seated height (0.047" or 1.20 mm versus 0.079" or 2.00 mm) due to manufacturer size code T designation. The T520T336M006ATE070 is active product status with ROHS3 compliance. This substitute is applicable only when reduced component height is compatible with circuit board layout and assembly clearance requirements.

Tertiary Substitutes: T520B336M006ATE0707622 and T520B336M006ATE0708000

Both T520B336M006ATE0707622 and T520B336M006ATE0708000 are parametric equivalents with identical electrical and mechanical specifications to the main part. These parts maintain the 0.079" maximum seated height and all electrical parameters. Both are active product status with ROHS3 compliance. These substitutes are differentiated by internal manufacturing codes and are functionally interchangeable with the main part and T520B336M006ATE070.

Frequently Asked Questions (FAQ)

Q: Can T520B336M006ATE070 be used as a direct replacement for T520B336M006ASE070?

A: Yes. The T520B336M006ATE070 is electrically and mechanically equivalent to the T520B336M006ASE070. Both parts share identical capacitance (33 µF), voltage rating (6.3 V), ESR (70 mOhm @ 100 kHz), package designation (1411), and maximum seated height (0.079"). The primary difference is packaging format: T520B336M006ATE070 is supplied in Tape & Reel format, while T520B336M006ASE070 is supplied in bulk. Both are suitable for surface mount assembly on 1411 (3528 Metric) footprints.

Q: What is the difference between T520B336M006ATE070 and T520T336M006ATE070?

A: Both parts are electrically identical with 33 µF capacitance, 6.3 V rating, and 70 mOhm ESR. The difference is in maximum seated height: T520B336M006ATE070 has a maximum seated height of 0.079" (2.00 mm), while T520T336M006ATE070 has a maximum seated height of 0.047" (1.20 mm). The T520T variant is suitable only when reduced component height is required for circuit board clearance or assembly constraints.

Q: Are T520B336M006ATE0707622 and T520B336M006ATE0708000 interchangeable with T520B336M006ATE070?

A: Yes. T520B336M006ATE0707622 and T520B336M006ATE0708000 are parametric equivalents with identical electrical specifications and mechanical dimensions to T520B336M006ATE070. All three parts share the same capacitance (33 µF), voltage rating (6.3 V), ESR (70 mOhm @ 100 kHz), package (1411), and maximum seated height (0.079"). The suffix codes represent internal manufacturing tracking and do not affect functional performance or compatibility.

Q: Why is the main part T520B336M006ASE070 classified as obsolete?

A: The T520B336M006ASE070 is obsolete and no longer in active production. Active equivalent parts are available within the KEMET KO-CAP® T520 series that provide identical electrical and mechanical performance with current product status and improved compliance certifications (ROHS3).

Q: What is the significance of RoHS compliance for substitute selection?

A: The main part T520B336M006ASE070 is RoHS non-compliant. All substitute parts (T520B336M006ATE070, T520T336M006ATE070, T520B336M006ATE0707622, and T520B336M006ATE0708000) are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the compliant substitutes are required.

Q: Can these parts be used in applications requiring high-reliability or military specifications?

A: The provided specifications do not include military grade or high-reliability certifications. Component selection for military, aerospace, or high-reliability applications requires verification against specific qualification standards beyond the parameters listed in this reference.

Q: What is MSL (Moisture Sensitivity Level) and why is it important?

A: All parts in this substitution group carry MSL 3 (168 Hours) rating. This indicates the maximum time the component can be exposed to ambient conditions (typically 30°C, 85% relative humidity) before requiring baking prior to soldering. MSL 3 components require baking if storage time exceeds 168 hours under these conditions. This specification is identical across all substitute parts.

Q: Are there any differences in operating temperature range between substitute parts?

A: No. All parts in this substitution group operate across the identical temperature range of -55°C to 105°C with a rated lifetime of 2000 hours at 105°C. Operating temperature performance is equivalent across all substitutes.
