Engineering Selection Recommendations
Vishay Sprague TR3 Series (TR3D337M010C0100, TR3D337M010C0125, TR3D337M010C0150, TR3E337M010C0060): These molded tantalum capacitors from the same manufacturer maintain ROHS3 compliance and offer improved moisture sensitivity (MSL 1 vs. 2A). The TR3D337M010C0125 provides the highest inventory availability (13,108 pcs) with 125 mOhm ESR and 3.10 mm height, matching the original part's physical footprint. The TR3E337M010C0060 offers the lowest ESR (60 mOhm) but requires 4.32 mm height clearance.
KYOCERA AVX TPSD337K010R0065: This part provides an upgrade path with tighter tolerance (±10% vs. ±20%), matching ESR (65 mOhm), and improved moisture sensitivity (MSL 1). It maintains ROHS3 compliance and the original 3.10 mm height constraint.
KEMET T491 and T494 Series: KEMET molded tantalum capacitors T491D337M010AT, T491X337M010AT, T494D337M010AH, and T494D337M010AT are ROHS3 compliant alternatives with MSL 1 rating. The T494D337M010AT is preferred over T494D337M010AH due to ROHS3 compliance. Both T494 variants offer 150 mOhm ESR with 3.10 mm height. T491 variants provide 500 mOhm ESR; T491D337M010AT maintains 3.10 mm height while T491X337M010AT requires 4.30 mm clearance.
Vishay Sprague 293D337X0010E2TE3: This molded alternative offers improved moisture sensitivity (MSL 1) and ROHS3 compliance but features higher ESR (500 mOhm) and increased height (4.32 mm), requiring PCB layout verification.
Frequently Asked Questions (FAQ)
Q: Can I use a substitute part with different ESR than the original 594D337X0010D2T?
A: Yes. Lower ESR values are acceptable as direct substitutes. The original part specifies 65 mOhm ESR. Substitutes with 60 mOhm, 100 mOhm, 125 mOhm, or 150 mOhm ESR maintain electrical compatibility. Higher ESR values (500 mOhm) are also functionally compatible but may affect circuit performance in applications sensitive to impedance characteristics.
Q: What is the difference between conformal coated and molded tantalum capacitors?
A: Both types meet the same electrical specifications for this application. Conformal coated parts (original 594D337X0010D2T) have a protective coating applied after assembly. Molded parts have the coating integrated during manufacturing. For this 330 µF 10 V application, both types are electrically equivalent and mechanically compatible within the 2917 package.
Q: Does moisture sensitivity level affect substitution eligibility?
A: MSL rating indicates moisture absorption during storage and handling. The original part is MSL 2A (4 weeks shelf life at specified humidity). Substitutes with MSL 1 (unlimited shelf life) are superior alternatives and fully compatible. Lower MSL ratings do not restrict substitution but indicate improved storage characteristics.
Q: Are there height constraints I should consider when selecting a substitute?
A: Yes. The original 594D337X0010D2T has a maximum seated height of 3.10 mm. Most substitutes maintain this height, but 293D337X0010E2TE3 and TR3E337M010C0060 require 4.32 mm clearance. Verify PCB layout and component placement constraints before selecting these alternatives.
Q: Can I substitute a ±10% tolerance part for the original ±20% tolerance specification?
A: Yes. TPSD337K010R0065 offers ±10% tolerance, which is tighter than the original ±20% specification. Tighter tolerance is an upgrade and maintains full compatibility.
Q: Why is T494D337M010AH listed but T494D337M010AT recommended instead?
A: Both parts are electrically and mechanically identical with 150 mOhm ESR and 3.10 mm height. T494D337M010AT is ROHS3 compliant, while T494D337M010AH is RoHS non-compliant. For applications requiring regulatory compliance, T494D337M010AT is the appropriate selection.
Q: What inventory considerations should guide my selection?
A: TR3D337M010C0125 offers the highest availability (13,108 pcs), followed by TPSD337K010R0065 (6,363 pcs). If long-term supply assurance is critical, these options provide the strongest inventory position among qualified substitutes.
