Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original TPSD226K035P0400. Selection between substitutes is determined by application-specific ESR requirements and packaging format availability.

For applications requiring ESR values lower than the original 400 mOhm specification, the TPM series parts (TPMD226K035R0070, TPME226K035R0060, TPME226K035R0100) provide ESR values ranging from 60 to 100 mOhm. These parts operate under Moisture Sensitivity Level 3 (168 hours) versus the original MSL 1 (Unlimited).

For applications requiring ESR values within or near the original specification, TPS series parts (TPSD226K035R0125, TPSD226K035R0200, TPSD226K035R0300, TPSE226K035R0125) maintain MSL 1 classification. The TAJ series alternatives (TAJD226K035RNJ, TAJE226K035RNJ) provide intermediate ESR options at 900 mOhm and 500 mOhm respectively.

Packaging format selection (Tape & Reel versus Cut Tape & Digi-Reel) depends on procurement and assembly process requirements and does not affect electrical performance.

Frequently Asked Questions (FAQ)

Q: Can TPSD226K035R0400 be used as a direct replacement for TPSD226K035P0400?

A: Yes. Both parts share identical electrical specifications (22 µF, 35 V, ±10%, 400 mOhm ESR) and mechanical compatibility (2917 package, surface mount). The difference is packaging format: P0400 uses Tape & Reel while R0400 uses Cut Tape & Digi-Reel format.

Q: What is the significance of ESR variation among substitute parts?

A: ESR affects circuit performance in high-frequency applications and power delivery circuits. Lower ESR values (60–100 mOhm from TPM series) reduce impedance and heat generation. Higher ESR values (300–900 mOhm) are suitable for general-purpose filtering applications. Selection depends on circuit requirements.

Q: Are TPM series parts (TPMD226K035R0070, TPME226K035R0060, TPME226K035R0100) fully compatible with the original part?

A: TPM series parts maintain identical capacitance, voltage rating, tolerance, package, and operating temperature range. The difference is Moisture Sensitivity Level: TPM parts are MSL 3 (168 hours) versus the original MSL 1 (Unlimited). This affects storage and handling requirements but does not impact electrical performance.

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

A: MSL 1 (Unlimited) allows indefinite storage without moisture baking requirements. MSL 3 (168 hours) requires components to be baked before reflow soldering if exposed to moisture for extended periods. Selection depends on storage conditions and manufacturing process capabilities.

Q: Can TAJ series parts (TAJD226K035RNJ, TAJE226K035RNJ) substitute for TPS series parts?

A: Yes, within the electrical and mechanical parameter constraints. Both series maintain 22 µF capacitance, 35 V rating, ±10% tolerance, and 2917 package compatibility. TAJ series parts have higher ESR values (500–900 mOhm) compared to the original 400 mOhm specification.
