Substitute Part Grouping Explanation

Substitution eligibility for the ECO-S2WB471EA is determined by strict adherence to the following parameters:

Capacitance: 470 µF (exact match required)
Voltage Rating: 450 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Lead Spacing: 0.394" (10.00mm) (exact match required)
Diameter: 1.378" (35.00mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Operating Temperature Range: -25°C to 105°C minimum (equal or wider range acceptable)
Polarization: Polar (exact match required)

All substitute parts listed meet these core electrical and mechanical parameters. Variations in height, ESR, ripple current ratings, lifetime at temperature, and compliance certifications do not disqualify a part from substitution eligibility, provided the above parameters are satisfied.

Engineering Selection Recommendations

Active Production Alternatives: For new designs and ongoing production, select from parts with Active product status. The Rubycon MXG, MXK, VXG, and VXH series, along with Chemi-Con KMS series parts, are all actively manufactured and available in high inventory quantities.

RoHS Compliance Consideration: If RoHS3 compliance is required for your application, the following parts satisfy this requirement: 381LX471M450A052 (Cornell Dubilier), 450MXG470MEFCSN35X40, 450MXK470MEFC35X35, 450VXG470MEFCSN35X45, 450VXH470MEFCSN35X40 (Rubycon), B43508B5477M000 (EPCOS - TDK), EKMS451VSN471MA40S, and EKMS451VSN471MA45S (Chemi-Con).

Extended Lifetime Options: Parts rated for 5000 Hrs @ 105°C provide longer operational life compared to the original 3000 Hrs specification. These include 450VXG470MEFC35X45, 450VXG470MEFCSN35X45, and 450VXH470MEFCSN35X40 from Rubycon.

Height Constraints: If PCB layout space is limited, the 450MXK470MEFC35X35 (1.457" height) and 450VXH470MEFCSN35X40 (1.654" height) offer the most compact form factors. For applications with less restrictive height requirements, all listed substitutes are mechanically compatible.

Avoid for New Designs: B43508B5477M000 carries a "Not For New Designs" status and should be used only for legacy system maintenance or repair applications.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different height than the original ECO-S2WB471EA?

A: Yes. All listed substitute parts maintain the same 0.394" (10.00mm) lead spacing and 1.378" (35.00mm) diameter, ensuring mechanical compatibility with the original PCB footprint. Height variations do not affect electrical performance or mounting compatibility for through-hole snap-in applications.

Q: What is the difference between 3000 Hrs and 5000 Hrs lifetime ratings?

A: Lifetime rating indicates the expected operational duration at maximum rated temperature (105°C) before capacitance degradation reaches specified limits. A 5000 Hrs rating provides extended service life compared to 3000 Hrs. Both ratings are acceptable substitutes for the original part; selection depends on application longevity requirements.

Q: Are all substitute parts pin-compatible with the ECO-S2WB471EA?

A: Yes. All substitute parts are radial, can-style snap-in capacitors with 0.394" (10.00mm) lead spacing and polar polarity. They are directly compatible with PCB footprints designed for the original part.

Q: Which substitute offers the best availability?

A: The 450MXG470MEFCSN35X40 from Rubycon has the highest inventory (500,300 pcs), followed by 450VXG470MEFCSN35X45 and 450VXH470MEFCSN35X40 (273,882 pcs each).

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS3 compliance is a manufacturing and material standard that does not alter the electrical specifications (capacitance, voltage rating, tolerance, or ripple current) of the capacitor.

Q: Can I substitute the ECO-S2WB471EA with a part rated for a lower voltage?

A: No. Voltage rating must match exactly at 450 V. Using a lower-rated capacitor creates risk of dielectric breakdown and component failure.
