Substitute Part Grouping Explanation

Substitution eligibility for the ECS-T0JD107R is determined by the following criteria:

Primary Compatibility Requirements:

• Capacitance value: 100 µF (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C to 125°C minimum (equal or wider range acceptable)
• Type: Molded Tantalum (exact match required)

Secondary Compatibility Factors:

• Voltage Rating: Must equal or exceed 6.3 V
• Tolerance: ±20% or tighter acceptable
• Physical dimensions must accommodate the specified package footprint

The substitute parts identified below meet all primary compatibility requirements and maintain functional equivalence within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

F931A107MNC (KYOCERA AVX): This substitute provides a 10 V voltage rating, exceeding the 6.3 V requirement of the main part. It maintains identical capacitance, tolerance, and package specifications. The part is active and ROHS3 compliant. Height clearance increases from 2.80mm to 3.00mm, requiring verification against PCB layout constraints. MSL rating of 3 indicates moisture sensitivity requiring controlled storage conditions.

TAJD107K016RNJ (KYOCERA AVX): This substitute offers a 16 V voltage rating with improved ±10% tolerance compared to the ±20% specification of the main part. It is active and ROHS3 compliant with MSL rating of 1, providing superior moisture handling characteristics. Height increases to 3.10mm, necessitating clearance verification. This part provides the highest voltage margin and tightest tolerance among available substitutes.

293D107X06R3D2TE3 (Vishay Sprague): This substitute matches the exact voltage rating of 6.3 V and maintains ±20% tolerance. It is active and ROHS3 compliant with MSL rating of 1. Height increases to 3.10mm. ESR specification of 700mOhm is provided, compared to the unspecified ESR of the main part. This option provides the closest electrical match to the original specification.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute with a higher voltage rating than the original 6.3 V specification?

A: Yes. Tantalum capacitors with higher voltage ratings are functionally compatible in circuits designed for lower voltages. The higher voltage rating provides additional safety margin and does not degrade performance in the application. TAJD107K016RNJ (16 V) and F931A107MNC (10 V) are both suitable for this purpose.

Q: What is the significance of the height difference between the main part and substitutes?

A: The main part has a seated height of 2.80mm, while substitutes range from 3.00mm to 3.10mm. This difference must be verified against PCB layout constraints, including component clearance to adjacent parts, solder mask design, and assembly equipment capabilities. Height verification is required before design release.

Q: Does the tolerance difference between ±20% and ±10% affect circuit performance?

A: Tolerance affects the acceptable range of capacitance values at delivery. TAJD107K016RNJ with ±10% tolerance provides tighter capacitance control compared to the ±20% specification of the main part and other substitutes. Selection depends on circuit requirements for capacitance accuracy.

Q: What does MSL rating mean for component handling?

A: MSL (Moisture Sensitivity Level) indicates the maximum time a component can be exposed to ambient conditions before requiring baking. MSL 1 (unlimited) allows indefinite storage without moisture control. MSL 3 (168 hours) requires controlled storage and baking before reflow soldering. F931A107MNC requires more stringent moisture management compared to other substitutes.

Q: Are all substitutes RoHS compliant?

A: Yes. All three substitute parts are ROHS3 compliant. The original ECS-T0JD107R is RoHS non-compliant. Substitution provides compliance improvement for new designs or manufacturing transitions.

Q: Which substitute provides the best overall compatibility?

A: 293D107X06R3D2TE3 matches the exact voltage rating of 6.3 V and maintains identical tolerance specifications. TAJD107K016RNJ offers superior tolerance and voltage margin with unlimited MSL rating. F931A107MNC provides intermediate voltage rating with active product status. Selection depends on specific circuit requirements and design constraints.
