ECO-S2DP331AA Equivalent & Substitute Parts

Part Overview

The ECO-S2DP331AA is a 330 µF, 200 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Panasonic Electronic Components. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The TS-UP series capacitor is rated for 2000 hours at 85°C with an ESR of 553 mOhm at 120 Hz, designed for general-purpose applications requiring through-hole mounting with 10 mm lead spacing.

Substitute Part Grouping Explanation

Substitution for the ECO-S2DP331AA is determined by strict equivalence in the following parameters: capacitance value (330 µF), voltage rating (200 V minimum), tolerance (±20%), package configuration (radial, can snap-in), lead spacing (10 mm), and mounting type (through-hole). All substitute parts must maintain identical physical footprint and electrical ratings to ensure direct board-level compatibility.

The substitute parts are grouped as follows:

Direct Equivalent (Same Voltage Rating): LLS2D331MELY maintains the 200 V rating with improved lifetime specifications and active product status.

Upgrade Option (Higher Voltage Rating): LLS2E331MELY provides 250 V rating with the same 330 µF capacitance, allowing operation in circuits designed for 200 V while providing additional voltage margin.

Alternative with Extended Temperature Range: LGU2D331MELY maintains 200 V rating but extends the operating temperature to 105°C, suitable for applications requiring higher thermal performance.

Engineering Selection Recommendations

LLS2D331MELY is the direct functional equivalent, offering identical electrical specifications at 200 V with improved lifetime (3000 hours vs. 2000 hours at 85°C) and active product status. This part is ROHS3 compliant and recommended for direct replacement in existing designs. Height is reduced to 30 mm, which may provide board layout advantages.

LLS2E331MELY is suitable for applications where voltage margin is required. The 250 V rating provides additional safety margin in circuits designed for 200 V operation while maintaining identical capacitance and footprint. This part is ROHS3 compliant and active.

LGU2D331MELY is appropriate for designs operating in elevated temperature environments up to 105°C. This part maintains 200 V rating and identical physical dimensions while extending thermal performance. ROHS3 compliance is confirmed.

All three substitute parts are manufactured by Nichicon with active product status and current availability, ensuring long-term supply chain stability compared to the obsolete ECO-S2DP331AA.

Frequently Asked Questions (FAQ)

Q: Can LLS2D331MELY be used as a direct replacement for ECO-S2DP331AA?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (200 V), tolerance (±20%), lead spacing (10 mm), and snap-in package configuration. The LLS2D331MELY offers improved lifetime specifications and active product status.

Q: What is the difference between LLS2D331MELY and LLS2E331MELY?

A: The primary difference is voltage rating: LLS2D331MELY is rated 200 V, while LLS2E331MELY is rated 250 V. Both maintain 330 µF capacitance and identical physical footprint. LLS2E331MELY provides additional voltage margin for circuits designed at 200 V.

Q: Is LGU2D331MELY compatible with the original ECO-S2DP331AA footprint?

A: Yes. LGU2D331MELY maintains the same lead spacing (10 mm), diameter (20 mm), and height (35 mm) as the original part. The key difference is extended operating temperature range to 105°C.

Q: Are all substitute parts RoHS compliant?

A: Yes. LLS2D331MELY, LLS2E331MELY, and LGU2D331MELY are all ROHS3 compliant, whereas the original ECO-S2DP331AA is RoHS non-compliant.

Q: What is the height difference between LLS2D331MELY and the original part?

A: LLS2D331MELY has a maximum seated height of 30 mm compared to 35 mm for the ECO-S2DP331AA. This 5 mm reduction may provide board layout benefits in space-constrained applications.

Q: Can I use a 250 V rated capacitor in a 200 V circuit?

A: Yes. LLS2E331MELY rated at 250 V can be used in circuits designed for 200 V operation. Higher voltage ratings provide additional safety margin and do not negatively affect circuit performance.
