Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAJS336M002RNJ is permissible when the following parameters remain constant or are upgraded:

• Capacitance value: 33 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Type: Molded Tantalum (exact match required)
• ESR: 1.5 Ohm (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match or better required)
• Mounting Type: Surface Mount (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Physical Dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm) (exact match required)

The voltage rating may be increased from 2.5 V to higher values (such as 10 V) when circuit design permits, as this represents an upgrade in electrical capability without reducing performance margins. RoHS3 compliance and REACH Unaffected status must be maintained.

Parameter Comparison

Engineering Selection Recommendations

The TLJK336M010R1500 is a direct substitute for the TAJS336M002RNJ based on matching capacitance, tolerance, ESR, operating temperature range, and package specifications. The primary difference is the increased voltage rating of 10 V versus 2.5 V, which provides enhanced electrical margin for applications requiring higher voltage withstand capability.

Both parts maintain Active product status and ROHS3 compliance. The TLJK336M010R1500 features a reduced maximum seated height of 0.039" (1.00mm) compared to 0.047" (1.20mm), which may provide design advantages in space-constrained applications. The Moisture Sensitivity Level increases from MSL 1 to MSL 3, requiring adherence to 168-hour storage and handling protocols during manufacturing.

Selection between these parts depends on circuit voltage requirements and manufacturing process capabilities regarding moisture sensitivity management.

Frequently Asked Questions (FAQ)

Q: Can TLJK336M010R1500 replace TAJS336M002RNJ in all applications?

A: The TLJK336M010R1500 is electrically compatible when the circuit voltage rating permits operation at 10 V. The higher voltage rating does not degrade performance in lower-voltage applications. However, the increased Moisture Sensitivity Level (MSL 3) requires compliance with 168-hour storage and handling protocols.

Q: What is the significance of the voltage rating difference?

A: The TAJS336M002RNJ is rated for 2.5 V maximum operation, while TLJK336M010R1500 is rated for 10 V. The substitute part provides a 4× voltage margin. Substitution is valid only when circuit design permits the use of a higher-rated component.

Q: Are the physical dimensions identical?

A: Both parts use the 1206 (3216 Metric) package with identical length and width (0.126" L x 0.063" W). The seated height differs: TAJS336M002RNJ maximum is 0.047" (1.20mm), while TLJK336M010R1500 maximum is 0.039" (1.00mm). This difference may affect PCB layout in height-constrained designs.

Q: What does Moisture Sensitivity Level (MSL) mean for component handling?

A: MSL 1 (TAJS336M002RNJ) permits unlimited shelf life without moisture absorption concerns. MSL 3 (TLJK336M010R1500) requires components to be used within 168 hours of package opening or stored in controlled humidity conditions. Manufacturing processes must account for this requirement.

Q: Are both parts RoHS3 compliant?

A: Yes, both TAJS336M002RNJ and TLJK336M010R1500 are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory standards.
