Engineering Selection Recommendations

Direct Replacement (Preferred): TPSA334M035R6000 from KYOCERA AVX is the primary direct equivalent. This part maintains identical electrical specifications including 6Ohm ESR and ±20% tolerance. Active product status and ROHS3 compliance ensure long-term availability and regulatory conformance. This selection is appropriate for applications requiring exact parameter matching to the original 7-1879062-6 specification.

Upgraded Specification: TPSA334K035R6000 from KYOCERA AVX provides improved tolerance performance at ±10% while retaining the 6Ohm ESR specification. This upgrade is suitable for applications where tighter capacitance tolerance enhances circuit performance. Active status and ROHS3 compliance are confirmed.

Functional Alternatives: TAJA334M035RNJ, TAJA334M035SNJ, TAJA334M035Y, and TAJS334M035RNJ from KYOCERA AVX satisfy all primary electrical and mechanical requirements with ESR values of 15Ohm. These parts are appropriate for applications where ESR variation within the 15Ohm range does not impact circuit performance. All maintain active product status and ROHS3 compliance.

293D334X0035A2TE3 from Vishay Sprague (TANTAMOUNT™ series) provides functional equivalence with 13Ohm ESR. This part is suitable for applications tolerant of ESR variation and offers an alternative manufacturer source. Active status and ROHS3 compliance are confirmed.

All substitute parts share identical operating temperature range (-55°C to 125°C), moisture sensitivity level (MSL 1), and mechanical dimensions with the original part.

Frequently Asked Questions (FAQ)

Q: Can TPSA334M035R6000 be used as a direct replacement for 7-1879062-6?

A: Yes. TPSA334M035R6000 matches all critical electrical and mechanical parameters: 0.33 µF capacitance, 35 V rating, ±20% tolerance, 6Ohm ESR, 1206 package, and -55°C to 125°C operating range. The part is active and ROHS3 compliant, making it the preferred direct equivalent.

Q: What is the difference between TPSA334M035R6000 and TPSA334K035R6000?

A: The primary difference is tolerance specification. TPSA334M035R6000 has ±20% tolerance, while TPSA334K035R6000 has ±10% tolerance. Both maintain 6Ohm ESR and all other electrical specifications. The ±10% tolerance part is an upgrade suitable for applications requiring tighter capacitance control.

Q: Why do some substitute parts have higher ESR values (15Ohm versus 6Ohm)?

A: ESR variation occurs across different manufacturer series and construction methods. Parts with 15Ohm ESR (TAJA series) remain functionally equivalent for applications where the circuit design accommodates this ESR range. ESR affects ripple current handling and thermal performance; circuit analysis determines acceptability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All active substitute parts listed (TPSA334M035R6000, TPSA334K035R6000, TAJA334M035RNJ, TAJA334M035SNJ, TAJA334M035Y, TAJS334M035RNJ, and 293D334X0035A2TE3) are ROHS3 compliant. The original 7-1879062-6 is REACH unaffected.

Q: Can I use TAJA334M035Y or TAJA334M035SNJ without packaging specification?

A: These parts are available without specified packaging designation in the provided data. Confirm packaging requirements (Tape & Reel versus bulk) with the supplier before procurement to ensure compatibility with assembly processes.

Q: What is the height difference between TAJS334M035RNJ and other TAJ series parts?

A: TAJS334M035RNJ has a maximum seated height of 0.047" (1.20mm) with manufacturer size code S, while other TAJ series parts have 0.071" (1.80mm) height with size code A. This dimensional difference may affect PCB layout and clearance considerations in space-constrained applications.

Q: Is 293D334X0035A2TE3 from Vishay Sprague interchangeable with KYOCERA AVX parts?

A: Yes, for functional equivalence. The Vishay Sprague 293D334X0035A2TE3 matches all primary specifications (0.33 µF, 35 V, ±20%, 1206 package) with 13Ohm ESR. It provides an alternative manufacturer source while maintaining electrical and mechanical compatibility.

Q: What inventory levels are available for substitute parts?

A: TPSA334M035R6000 has 888 pcs in stock, TPSA334K035R6000 has 924 pcs, 293D334X0035A2TE3 has 4028 pcs, TAJA334M035RNJ has 2956 pcs, TAJA334M035SNJ has 763 pcs, TAJA334M035Y has 776 pcs, and TAJS334M035RNJ has 1168 pcs. The original 7-1879062-6 has 1143 pcs available as new original stock.
