Engineering Selection Recommendations

Primary Recommendation: T520D227M006ATE050

The T520D227M006ATE050 is the direct KEMET equivalent with active product status. This part maintains identical electrical and mechanical specifications to the obsolete T520D227M006ASE050. ROHS3 compliance supports modern manufacturing and environmental regulatory requirements. Packaging in Cut Tape (CT) and Digi-Reel® formats provides flexibility for both manual and automated assembly processes. Inventory availability of 1642 units ensures supply continuity.

Secondary Recommendation: TCJD227M006R0050 or TCJD227M006R0050E

KYOCERA AVX TCJD series parts provide cross-manufacturer equivalence with identical electrical performance and 0.122" seated height matching the original specification. Both variants carry ROHS3 compliance and active product status. The TCJD227M006R0050E variant includes extended environmental testing certification. Inventory levels support production requirements.

Alternative for Reduced Height Applications: TCJY227M006R0050E

The TCJY227M006R0050E offers a reduced seated height of 0.079" (2.00 mm) compared to the standard 0.122" (3.10 mm). This variant is suitable for space-constrained PCB designs where vertical clearance is limited. ROHS3 compliance and highest inventory availability (2070 units) support immediate deployment. Electrical specifications remain fully equivalent.

Compliance Consideration:

Applications requiring ROHS3 compliance should prioritize T520D227M006ATE050, T520D227M006ATE0502478, or any KYOCERA AVX TCJ series part. The original T520D227M006ASE050 and T520D227M006AHE050 are non-compliant and suitable only for legacy or non-regulated applications.

Frequently Asked Questions (FAQ)

Q: Can T520D227M006ATE050 directly replace T520D227M006ASE050 in existing designs?

A: Yes. The T520D227M006ATE050 maintains identical electrical specifications (220 µF, 6.3 V, 50 mOhm ESR), mechanical dimensions (2917 package, 0.122" height), and operating characteristics (-55°C to 105°C, 2000 Hrs @ 105°C). The only difference is product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant). No circuit redesign or PCB modification is required.

Q: What is the difference between KEMET T520D and KYOCERA AVX TCJD series parts?

A: Both series provide identical electrical performance and mechanical compatibility. The primary differences are manufacturer, packaging format options, and RoHS compliance status. KEMET T520D parts are available in Cut Tape and Digi-Reel formats. KYOCERA AVX TCJD parts are supplied in Tape & Reel format. All KYOCERA AVX variants carry ROHS3 compliance, while KEMET T520D227M006ATE050 and T520D227M006ATE0502478 are ROHS3 compliant.

Q: Why do TCJY series parts have a lower seated height (0.079") compared to TCJD series (0.122")?

A: The TCJY and TCJD designations indicate different internal construction and lead frame designs within the KYOCERA AVX TCJ polymer capacitor family. Both maintain identical electrical specifications and 2917 package footprint. The height difference reflects manufacturing process variations. Selection depends on available PCB clearance. Electrical performance is equivalent.

Q: Are KEMET T520D227M006ATE050 and T520D227M006ATE0502478 interchangeable?

A: Yes. Both parts are electrically and mechanically identical. The T520D227M006ATE0502478 includes an extended part number suffix (2478) that may reference internal KEMET tracking or customer-specific configuration. Electrical specifications, package dimensions, and performance characteristics are identical. Both carry ROHS3 compliance and active product status.

Q: Which substitute part offers the highest inventory availability?

A: TCJY227M006R0050E from KYOCERA AVX has the highest inventory level at 2070 units. This part provides ROHS3 compliance, active product status, and reduced seated height (0.079"). If standard height (0.122") is required, T520D227M006ATE050 offers 1642 units in stock.

Q: Can I use TCJY227M006R0050 (without "E" suffix) instead of TCJY227M006R0050E?

A: Yes. Both TCJY variants are electrically and mechanically equivalent. The "E" suffix indicates extended environmental testing or certification. Selection between TCJY227M006R0050 and TCJY227M006R0050E depends on application-specific environmental or reliability requirements. Electrical performance and physical compatibility are identical.

Q: What does MSL 3 (168 Hours) mean for PCB assembly?

A: Moisture Sensitivity Level 3 indicates the component requires controlled storage and handling conditions. The 168-hour specification means the part can be exposed to ambient conditions (typically 30°C, 60% relative humidity) for up to 168 hours before soldering. All substitute parts carry identical MSL 3 rating, requiring equivalent moisture control procedures during assembly.

Q: Are there any height restrictions when selecting between substitute parts?

A: Yes. If PCB clearance is limited, TCJY227M006R0050 or TCJY227M006R0050E (0.079" height) are suitable. For standard applications, KEMET T520D series and KYOCERA AVX TCJD series (0.122" height) are appropriate. Verify available vertical clearance on the target PCB before final part selection.
