ECO-S2DB152DA Equivalent & Substitute Parts

Part Overview

The ECO-S2DB152DA is a 1500 µF, 200 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components in the TS-HB series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring high capacitance at elevated voltage ratings. The part is currently obsolete, making equivalent substitutes necessary for ongoing system support and new designs. Substitute parts must maintain the same electrical specifications (capacitance, voltage rating, tolerance) and physical form factor (radial snap-in package, 10 mm lead spacing, 30 mm diameter can) to ensure direct compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

• Electrical Match: Capacitance (1500 µF), voltage rating (200 V), and tolerance (±20%) must be identical
• Physical Form Factor: Package type must be radial, can-style snap-in with 10 mm lead spacing and 30 mm diameter
• Thermal Specifications: Operating temperature range (-40°C to 105°C) and lifetime rating (3000 Hrs @ 105°C) must be met or exceeded
• Mounting Configuration: Through-hole radial mounting only; no surface-mount variants

All substitute parts listed below meet these core requirements. Variations in ESR (Equivalent Series Resistance), ripple current ratings, and can height are secondary parameters that do not prevent substitution but may affect performance in ripple-current-sensitive applications.

Engineering Selection Recommendations

All substitute parts listed are active products with ROHS3 compliance, ensuring regulatory alignment for new designs and ongoing production. The ECO-S2DB152DA is obsolete; direct replacement with an active equivalent is required.

Primary Recommendation: LGU2D152MELB (Nichicon) matches the original can height (1.969" / 50.00 mm) and maintains identical thermal specifications (3000 Hrs @ 105°C). This part provides the closest physical and electrical compatibility with the original design.

Alternative Selections:

• B43508A2158M000 (EPCOS - TDK Electronics): Offers the lowest ESR (75 mOhm @ 100 Hz), beneficial for applications with high ripple current requirements. Shorter can height (1.850" / 47.00 mm) may require PCB layout verification.
• LGN2D152MELB40 (Nichicon): Compact form factor (1.654" / 42.00 mm height) with high ripple current capability (2.8 A @ 120 Hz, 4.2 A @ 50 kHz). Suitable for space-constrained designs.
• LGW2D152MELB45 (Nichicon): Enhanced ripple current performance (4.62 A @ 120 Hz, 6.93 A @ 50 kHz) for demanding applications.

Consideration for MAL209432152E3: This part has a reduced lifetime rating (2000 Hrs @ 105°C versus 3000 Hrs for other substitutes) and a narrower operating temperature range (-25°C to 105°C). Use only if application constraints permit.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different can height? A: Yes. All listed substitutes maintain the same 10 mm lead spacing and 30 mm diameter, ensuring electrical compatibility. Can height variations (ranging from 1.654" to 2.047") do not affect electrical function but require PCB layout verification to confirm mechanical clearance in your specific application.

Q: What is the significance of ESR differences among substitutes? A: ESR (Equivalent Series Resistance) affects ripple current handling and heat dissipation. Lower ESR values (such as B43508A2158M000 at 75 mOhm) are advantageous in high-ripple-current applications. The original ECO-S2DB152DA has 155 mOhm ESR; substitutes with lower ESR provide improved performance in this regard.

Q: Are all substitutes RoHS compliant? A: Yes. All active substitute parts listed are ROHS3 compliant, meeting current regulatory requirements for electronic components in most markets.

Q: Does the lifetime rating difference matter? A: The original ECO-S2DB152DA and most substitutes are rated for 3000 Hrs @ 105°C. MAL209432152E3 is rated for 2000 Hrs @ 105°C. For applications requiring extended operational life at elevated temperatures, select a substitute with the 3000 Hrs rating.

Q: Can I substitute based on ripple current ratings alone? A: No. Ripple current is a secondary parameter. Primary substitution criteria are capacitance (1500 µF), voltage rating (200 V), tolerance (±20%), and physical form factor (radial snap-in, 10 mm lead spacing, 30 mm diameter). Ripple current ratings should be evaluated after confirming electrical and mechanical compatibility.

Q: What is the operating temperature range for all substitutes? A: Most substitutes operate from -40°C to 105°C, matching the original part. MAL209432152E3 has a narrower range (-25°C to 105°C). Confirm your application's temperature requirements before selection.
