ECO-S2EB471BA Equivalent & Substitute Parts

Part Overview

The ECO-S2EB471BA is a 470 µF, 250 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Panasonic Electronic Components. This part operates across -40°C to 105°C with a rated lifetime of 3000 hours at 105°C and is classified as obsolete. Due to its obsolete status, equivalent substitute parts from active manufacturers are necessary for ongoing production and maintenance applications requiring 470 µF capacitance at 250 V rated voltage with through-hole snap-in mounting.

Substitute Part Grouping Explanation

Substitute parts are grouped into two categories based on electrical and mechanical compatibility with the ECO-S2EB471BA:

Direct Substitutes (250 V Rated): Parts meeting all critical parameters—470 µF capacitance, 250 V voltage rating, ±20% tolerance, through-hole snap-in package, 10.00 mm lead spacing, and 22.00 mm case diameter. These parts are electrically and mechanically interchangeable. Product status and compliance certifications vary among manufacturers.

Similar Substitutes (Lower Voltage Ratings): Parts with 470 µF capacitance and ±20% tolerance in identical package configuration but rated at 160 V, 180 V, or 200 V. These are suitable only for applications where the circuit voltage does not exceed the substitute part's rated voltage. Height variations exist within this group.

The following parameters determine substitution eligibility:

Capacitance: 470 µF (fixed)
Tolerance: ±20% (fixed)
Package: Radial, Can - Snap-In (fixed)
Lead Spacing: 0.394" / 10.00 mm (fixed)
Case Diameter: 0.866" / 22.00 mm (fixed)
Mounting: Through Hole (fixed)
Voltage Rating: 250 V (direct) or lower (similar)

Engineering Selection Recommendations

For Direct Replacement (250 V Applications):

Select from active manufacturer parts: 381LX471M250H052 (Cornell Dubilier), B43254E2477M (EPCOS - TDK), B43508E2477M000 (EPCOS - TDK), LGN2E471MELZ40 (Nichicon), or LGW2E471MELZ40 (Nichicon). All direct substitutes are ROHS3 compliant and rated for 3000 hours at 105°C. Height variations range from 1.575" to 2.047", requiring verification of available PCB clearance. The B43508E2477M000 and LGN2E471MELZ40 offer the most compact height at 1.654" (42.00 mm).

For Lower Voltage Applications (160 V, 180 V, or 200 V):

Use similar substitutes only when circuit voltage does not exceed the part's rated voltage. The 200 V rated parts (200HXG470MEFCSN22X35 and 200HXC470MEFCSN22X40) maintain 3000-hour lifetime at 105°C, except 200HXC470MEFCSN22X40 which is rated for 2000 hours. The 200MXC470MEFC22X35 is RoHS non-compliant and should be avoided in new designs requiring RoHS certification.

Compliance Considerations:

All recommended direct substitutes carry ROHS3 compliance. For applications requiring REACH compliance, verify individual part certifications with manufacturers, as REACH status varies among suppliers.

Frequently Asked Questions (FAQ)

Q: Can I use a 200 V rated capacitor in place of the 250 V ECO-S2EB471BA?

A: No. The ECO-S2EB471BA is rated for 250 V operation. Using a 200 V rated part in a 250 V circuit exceeds the capacitor's voltage rating and creates reliability and safety risks. Use only 250 V rated direct substitutes for this application.

Q: What is the significance of height differences among substitute parts?

A: Height variations range from 1.575" to 2.047" across available substitutes. Verify PCB layout clearance before selection. Taller parts (such as 381LX471M250H052 at 2.047") may not fit in space-constrained designs, while shorter parts (such as LGW2E471MELZ40 at 1.575") offer better fit in compact layouts.

Q: Are all substitute parts RoHS compliant?

A: Most direct substitutes are ROHS3 compliant. The 200MXC470MEFC22X35 is RoHS non-compliant and should not be used in applications requiring RoHS certification. Verify compliance requirements for your specific application.

Q: What is the difference between direct and similar substitutes?

A: Direct substitutes match the 250 V voltage rating and are electrically interchangeable. Similar substitutes have lower voltage ratings (160 V, 180 V, or 200 V) and are suitable only for applications operating below their rated voltage. Do not use similar substitutes in 250 V circuits.

Q: Does capacitance tolerance affect substitution?

A: All listed substitutes maintain ±20% tolerance, matching the original part. Tolerance is not a differentiating factor for substitution eligibility.

Q: Why is the ECO-S2EB471BA obsolete?

A: Panasonic has discontinued this part. Active manufacturer alternatives from Cornell Dubilier, EPCOS - TDK, and Nichicon provide equivalent performance and are recommended for new designs and ongoing production.
