Substitute Part Grouping Explanation

Substitution eligibility for the ECO-S2AP332CA is determined by strict equivalence across the following parameters:

Capacitance: 3300 µF (exact match required)
Voltage Rating: 100 V (exact match required)
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)
Operating Temperature Range: -40°C to 85°C (exact match required)

All identified substitute parts meet these core electrical and mechanical parameters. Variations in physical dimensions (diameter and height), ESR characteristics, and ripple current ratings are permissible within the constraints of the snap-in package form factor and lead spacing specification.

Engineering Selection Recommendations

All substitute parts listed maintain active product status with current manufacturer support, contrasting with the obsolete ECO-S2AP332CA. Selection among substitutes should prioritize the following criteria:

Direct Dimensional Match: SLPX332M100C9P3 provides identical physical dimensions (0.984" diameter, 1.969" height) to the original part, minimizing PCB layout modifications and mechanical clearance concerns.

Compliance Status: All substitute parts carry ROHS3 compliance certification, ensuring regulatory alignment for new designs and procurement cycles. The original ECO-S2AP332CA does not specify RoHS status.

Electrical Performance: SLPX332M100E7P3, SLPX332M100H5P3, and SLPX332M100C9P3 offer improved ESR characteristics at 80 mOhm compared to the original 90 mOhm specification, providing enhanced ripple current handling and thermal performance.

Lifetime Consideration: B41231A9338M000 specifies 2000 hours at 85°C, which is lower than the original 3000-hour rating. This part is suitable only for applications where reduced lifetime is acceptable.

Inventory Availability: SLPX332M100E7P3 maintains the highest inventory level (274,082 units), supporting immediate procurement needs.

Frequently Asked Questions (FAQ)

Q: Can SLPX332M100C9P3 be used as a direct replacement for ECO-S2AP332CA?

A: Yes. SLPX332M100C9P3 matches all critical electrical parameters (3300 µF, 100 V, ±20% tolerance, 3000 Hrs @ 85°C) and physical dimensions (0.984" diameter, 1.969" height, 0.394" lead spacing). The part is active with ROHS3 compliance and lower ESR (80 mOhm vs. 90 mOhm).

Q: What is the difference between the 380LX and SLPX series substitutes?

A: Both series meet the core electrical specifications. The 380LX series (380LX332M100J052, 380LX332M100K042) maintains 90 mOhm ESR matching the original part. The SLPX series (SLPX332M100C9P3, SLPX332M100E7P3, SLPX332M100H5P3) offers improved 80 mOhm ESR. Physical dimensions vary across both series to accommodate different package form factors within the snap-in configuration.

Q: Is B41231A9338M000 suitable for all applications?

A: B41231A9338M000 is electrically equivalent but specifies 2000 hours lifetime at 85°C versus the original 3000-hour rating. This part is suitable only for applications where the reduced lifetime specification does not compromise system reliability requirements.

Q: Do all substitute parts require PCB layout changes?

A: SLPX332M100C9P3 requires no layout changes due to identical dimensions and lead spacing. Other substitutes feature different diameters and heights; PCB clearance verification is necessary before implementation.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts carry ROHS3 compliance certification. The original ECO-S2AP332CA does not specify RoHS status.
