Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Matching Parameters:

• Capacitance: 1 µF (exact match required)
• Voltage Rating: 50 V (exact match required)
• Package / Case: 1411 (3528 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Type: Molded Tantalum (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Secondary Allowable Variations:

• Tolerance: ±20% or tighter (±10% acceptable as upgrade)
• ESR (Equivalent Series Resistance): 6.0 Ohm to 7.0 Ohm (within acceptable range)
• Manufacturer: Vishay Sprague, KEMET, KYOCERA AVX (qualified manufacturers)
• RoHS Status: ROHS3 Compliant (mandatory)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All identified substitutes meet these criteria and are suitable for direct replacement in applications requiring the 293D105X0050B2TE3.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and full ROHS3 compliance, ensuring regulatory and supply chain continuity. Selection between substitutes is based on the following factors:

293D105X9050B2TE3 (Vishay Sprague Upgrade): This part offers improved tolerance specification at ±10% compared to the ±20% of the main part, while maintaining identical electrical and mechanical characteristics. It is suitable for applications requiring tighter capacitance tolerance within the same manufacturer ecosystem.

T491B105M050AT (KEMET): This part provides equivalent electrical performance with a lower ESR specification of 6.0 Ohm and documented lifetime rating of 2000 Hrs @ 125°C. It is suitable for applications where ESR performance or thermal lifetime data is a selection criterion.

TAJB105M050RNJ (KYOCERA AVX): This part maintains all critical electrical and mechanical parameters with an ESR specification of 7.0 Ohm. It is suitable for applications requiring multi-source qualification or KYOCERA AVX supply chain preference.

Frequently Asked Questions (FAQ)

Q: Can the 293D105X9050B2TE3 be used as a direct replacement for the 293D105X0050B2TE3?

A: Yes. The 293D105X9050B2TE3 is a direct substitute with identical capacitance, voltage rating, package, and operating temperature range. The ±10% tolerance is tighter than the ±20% specification of the main part and does not affect interchangeability.

Q: Are the KEMET T491B105M050AT and KYOCERA AVX TAJB105M050RNJ suitable for the same application?

A: Yes. Both parts match the critical electrical specifications (1 µF, 50 V, ±20% tolerance) and mechanical package (1411 / 3528 Metric) of the main part. Minor variations in ESR (6.0 Ohm vs. 7.0 Ohm) fall within acceptable operating ranges for general-purpose tantalum capacitor applications.

Q: What is the significance of the 1411 (3528 Metric) package designation?

A: The 1411 package code refers to the physical dimensions 3.50mm x 2.80mm, which is the industry-standard surface mount footprint for this capacitance and voltage class. All substitute parts use this identical package, ensuring PCB layout compatibility without redesign.

Q: Does tolerance affect the choice of substitute?

A: Tolerance affects circuit performance only in applications with strict capacitance requirements. The ±10% tolerance of the 293D105X9050B2TE3 is superior to the ±20% tolerance of the main part and other substitutes. For general-purpose applications, all tolerance grades are functionally equivalent.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant certification, matching the compliance status of the main part and ensuring regulatory alignment for end-use applications.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions and does not require special handling, storage, or reflow precautions. All substitute parts share this specification.
