TPSD336K035P0300 Equivalent & Substitute Parts

Part Overview

The TPSD336K035P0300 is a 33 µF molded tantalum capacitor rated at 35 V, manufactured by KYOCERA AVX in the TPS series. This surface mount component features a 2917 (7343 Metric) package with 300 mOhm equivalent series resistance and operates across -55°C to 125°C. The part is ROHS3 compliant with MSL 1 (unlimited moisture sensitivity). Substitute parts are identified when electrical parameters (capacitance, voltage rating, tolerance) and mechanical specifications (package, case size, mounting type) remain constant while secondary characteristics such as ESR, series designation, or packaging format may vary.

Substitute Part Grouping Explanation

Substitution validity is determined by matching core electrical specifications: 33 µF capacitance, 35 V voltage rating, and ±10% tolerance. All substitute parts maintain the 2917 (7343 Metric) package footprint and surface mount configuration, ensuring mechanical and electrical compatibility at the board level.

Secondary parameters that may differ between the main part and substitutes include:

Equivalent Series Resistance (ESR): ranges from 50 mOhm to 900 mOhm
Series designation: TPS, TPM, TRM (KYOCERA AVX) or T491 (KEMET)
Packaging format: Tape & Reel (TR), Cut Tape (CT) & Digi-Reel®
Manufacturer Size Code: D or E
Moisture Sensitivity Level: MSL 1 or MSL 3

These variations do not affect functional substitution when the primary electrical and mechanical parameters align.

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and operate within the -55°C to 125°C temperature range. Selection between substitutes depends on application-specific ESR requirements and packaging logistics.

For applications requiring lower ESR performance, TPME336K035R0050 (50 mOhm) and TRME336K035R0050 (50 mOhm, automotive-rated AEC-Q200) provide superior characteristics. TRME336K035R0050 is designated for automotive applications with AEC-Q200 qualification.

For standard general-purpose applications, TPSD336K035R0200 (200 mOhm) and TPSE336K035R0100 (100 mOhm) offer balanced performance. TPSD336K035R0300 and TPSD336K035R0300 are functionally identical, differing only in packaging format (Tape & Reel versus Cut Tape & Digi-Reel®).

KEMET T491 series parts (T491D336K035AT, T491X336K035AT) provide cross-manufacturer alternatives with equivalent electrical specifications and ROHS3 compliance. T491D336K035AT specifies 2000 Hrs @ 125°C lifetime rating.

MSL 3 rated parts (TPME336K035R0065, TPME336K035R0050, TRME336K035R0050) require 168-hour moisture bake conditioning prior to reflow soldering; MSL 1 parts require no such conditioning.

Frequently Asked Questions (FAQ)

Q: Can TPSD336K035P0300 be directly replaced with TPSD336K035R0300?

A: Yes. Both parts are identical in electrical and mechanical specifications (33 µF, 35 V, ±10%, 300 mOhm ESR, 2917 package, MSL 1). The difference is packaging format: TPSD336K035P0300 is supplied in Tape & Reel (TR), while TPSD336K035R0300 is supplied in Cut Tape (CT) & Digi-Reel®. Board-level performance is equivalent.

Q: What is the impact of selecting a substitute with different ESR?

A: ESR affects ripple current handling and thermal performance. Lower ESR (50–100 mOhm) reduces heat generation and improves high-frequency performance. Higher ESR (600–900 mOhm) increases thermal dissipation but remains within the rated operating envelope. Selection depends on circuit requirements for ripple current and thermal margin.

Q: Are KYOCERA AVX and KEMET parts interchangeable?

A: Yes, when electrical and mechanical parameters match. T491D336K035AT and T491X336K035AT (KEMET) are functionally equivalent to KYOCERA AVX TPS series parts at the same capacitance, voltage, and package specifications. Both manufacturers meet ROHS3 compliance and operate across -55°C to 125°C.

Q: What does MSL 3 mean, and does it affect substitution?

A: MSL 3 (Moisture Sensitivity Level 3) requires 168-hour moisture bake conditioning before reflow soldering. MSL 1 parts require no conditioning. If the original design uses MSL 1 parts, MSL 3 substitutes require additional process steps. If the design already accommodates MSL 3 handling, MSL 3 substitutes are directly compatible.

Q: Can I substitute TPME336K035R0050 (50 mOhm) for TPSD336K035P0300 (300 mOhm)?

A: Yes, electrically and mechanically. TPME336K035R0050 provides superior ESR performance (50 mOhm versus 300 mOhm) and is a direct upgrade. However, it is MSL 3 rated, requiring moisture bake conditioning. Verify that manufacturing processes accommodate MSL 3 handling requirements.

Q: Is TRME336K035R0050 suitable for non-automotive applications?

A: TRME336K035R0050 is AEC-Q200 qualified for automotive use but is not restricted to automotive applications. It can be used in general-purpose circuits and offers the same electrical performance as TPME336K035R0050 with automotive-grade reliability certification.

Q: What is the difference between TAJD336K035RNJ and TAJE336K035RNJ?

A: Both are TAJ series parts with identical electrical specifications (33 µF, 35 V, 900 mOhm ESR). TAJD336K035RNJ is supplied in Cut Tape (CT) & Digi-Reel®; TAJE336K035RNJ is supplied in Tape & Reel (TR). Functional performance is identical; selection depends on packaging logistics.
