Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 35TQC10M is determined by strict equivalence across the following parameters:

• Capacitance: 10 µF (exact match required)
• Voltage Rating: 35 V (exact match required)
• ESR: 120 mOhm @ 100 kHz (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Tolerance: ±20% (exact match required)
• Type: Molded Tantalum Polymer (exact match required)

Substitute parts must maintain identical electrical performance and physical footprint compatibility. Variations in operating temperature range, lifetime ratings, or physical height do not disqualify substitution when all primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The 35TQC10M is designated Last Time Buy status, making transition to an active substitute part necessary for ongoing production requirements.

The Panasonic 35TQC10MYF is the manufacturer-recommended direct replacement within the same POSCAP™ TQC series. This part maintains identical electrical specifications and footprint compatibility. The 35TQC10MYF features a reduced seated height of 0.075" (1.90mm) compared to the original 0.079" (2.00mm), which provides improved board-level clearance without affecting electrical performance. Both parts are ROHS3 Compliant and REACH Unaffected.

The KEMET T521V106M035ATE120 is a cross-manufacturer equivalent from the KO-CAP® T521 series. This part matches all critical electrical parameters and package dimensions. The T521V106M035ATE120 extends the operating temperature range to -55°C to 125°C and provides 2000 hours lifetime at 125°C, offering enhanced thermal performance. This part is also ROHS3 Compliant and REACH Unaffected, with Moisture Sensitivity Level (MSL) 3 (168 Hours).

Both substitute parts are currently in active production status with confirmed inventory availability, ensuring reliable long-term supply.

Frequently Asked Questions (FAQ)

Q: Can the 35TQC10MYF be used as a direct replacement for the 35TQC10M?

A: Yes. The 35TQC10MYF is the manufacturer-recommended substitute with identical capacitance (10 µF), voltage rating (35 V), ESR (120 mOhm @ 100 kHz), and package (2917 / 7343 Metric). The reduced seated height of 0.075" (1.90mm) versus 0.079" (2.00mm) does not affect electrical compatibility or PCB footprint placement.

Q: What are the key differences between the Panasonic 35TQC10MYF and KEMET T521V106M035ATE120?

A: Both parts are electrically equivalent with matching capacitance, voltage, ESR, and package specifications. The primary differences are: (1) Manufacturer: Panasonic versus KEMET; (2) Operating temperature range: 35TQC10MYF operates to 105°C, while T521V106M035ATE120 operates to 125°C; (3) Lifetime rating: 35TQC10MYF rated 2000 Hrs @ 105°C, T521V106M035ATE120 rated 2000 Hrs @ 125°C; (4) Moisture Sensitivity: T521V106M035ATE120 specifies MSL 3 (168 Hours).

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. The 35TQC10MYF and T521V106M035ATE120 are both ROHS3 Compliant and REACH Unaffected, matching the compliance status of the original 35TQC10M.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All three parts share identical package dimensions (0.287" L x 0.169" W / 7.30mm x 4.30mm) and the same 2917 (7343 Metric) footprint. The minor height variation (0.075" to 0.079") does not affect PCB layout or assembly compatibility.

Q: Why is the 35TQC10M designated Last Time Buy?

A: Last Time Buy status indicates Panasonic has discontinued production of this part number. The 35TQC10MYF serves as the active production replacement within the same POSCAP™ TQC series, ensuring design continuity with improved availability.
