Tolerance: ±20% (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Mounting Type: Through Hole (exact match required)
Polarization: Polar (exact match required)

Secondary Compatibility Parameters:

ESR @ 120Hz: 90 mOhm (target specification)

Engineering Selection Recommendations

Direct Equivalent (100 V Rating):

The 380LX332M100K042 from Cornell Dubilier Electronics is the primary direct equivalent. It matches all primary substitution criteria with identical electrical specifications and active product status. ROHS3 compliance provides regulatory advantage over the obsolete ECO-S2AP332DA. Height variation of 0.079" (2.00 mm) requires PCB layout verification.

The SLPX332M100C9P3 from Cornell Dubilier Electronics meets all primary criteria with improved ESR specification (80 mOhm versus 90 mOhm). Active product status and ROHS3 compliance support long-term availability. Height of 1.969" (50.00 mm) requires clearance verification in existing designs.

The B41231B9338M000 from EPCOS - TDK Electronics provides 100 V equivalence with active status and ROHS3 compliance. Lifetime specification of 2000 hours at 85°C is reduced compared to the original 3000 hours, requiring thermal analysis for applications with extended operating duration at elevated temperatures.

Lower Voltage Alternatives (80 V and 63 V Ratings):

Parts rated at 80 V and 63 V are suitable only for applications where the circuit design operates at or below these voltage levels. The 80USG3300MEFCSN30X30 and 80MXG3300MEFCSN30X30 from Rubycon provide 80 V operation with active status. The 63VXG3300MEFCSN30X30 offers extended lifetime (5000 hours at 105°C) and wider operating temperature range (-40°C to 105°C) for 63 V applications.

The 35KXF3300MEFC30X20 from Rubycon is suitable only for 35 V circuit designs, offering the most compact form factor at 0.866" (22.00 mm) height.

Not Recommended for New Designs:

The 63MXC3300MEFCSN30X25 from Rubycon carries "Not For New Designs" status and should not be selected for new applications despite meeting electrical criteria.

Frequently Asked Questions (FAQ)

Q: Can I use a lower voltage rated capacitor (80 V or 63 V) as a substitute for the 100 V ECO-S2AP332DA?

A: Lower voltage rated capacitors are suitable only if your circuit design operates at or below that voltage rating. A 100 V circuit cannot use an 80 V or 63 V capacitor. Voltage rating represents the maximum safe operating voltage; exceeding this rating causes capacitor failure.

Q: What is the significance of ESR (Equivalent Series Resistance) in capacitor selection?

A: ESR affects ripple current handling and heat generation. The ECO-S2AP332DA specifies 90 mOhm @ 120Hz. The SLPX332M100C9P3 offers 80 mOhm, providing lower impedance and reduced heat dissipation. Parts with unspecified ESR require verification with the manufacturer if ripple current performance is critical to your application.

Q: Does the height difference between substitute parts affect compatibility?

A: Yes. The ECO-S2AP332DA has a maximum seated height of 1.575" (40.00 mm). Substitute parts range from 0.866" to 2.047" in height. Verify clearance in your PCB layout and enclosure design before selecting a substitute with different height specifications.

Q: What does ROHS3 compliance mean for my application?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances regulations, restricting lead and other hazardous materials. The original ECO-S2AP332DA is REACH Affected but not explicitly ROHS3 compliant. All recommended substitutes are ROHS3 compliant, providing regulatory alignment with current environmental standards.

Q: Can I use the B41231B9338M000 if my application requires 3000 hours lifetime at 85°C?

A: The B41231B9338M000 specifies 2000 hours at 85°C, which is 1000 hours less than the original specification. If your application requires the full 3000-hour lifetime at 85°C, select 380LX332M100K042, 380LX332M100J052, or SLPX332M100C9P3 instead.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All listed substitutes use radial, can snap-in package with through-hole mounting and 0.394" (10.00 mm) lead spacing, matching the original ECO-S2AP332DA package specifications. Physical dimensions vary; verify PCB layout compatibility before procurement.
