Engineering Selection Recommendations

For Direct Replacement (400 V Rating):

Select from active-status parts with ROHS3 compliance for new production: 400USG470MEFCSN35X30, 861221386021, LLS2G471MELC, or SLPX471M400H7P3. These parts maintain the 400 V voltage specification and 3000-hour lifetime rating. Verify mechanical fit within your PCB layout, as height variations range from 1.260" to 1.575".

The 380LQ471M400A022 is active and ROHS3 compliant but offers reduced lifetime (2000 hours vs. 3000 hours). Use only where lifetime requirements permit.

The B43501A9477M000 carries "Not For New Designs" status and should not be selected for new production despite superior ESR and lifetime characteristics.

For Enhanced Margin Applications:

The 380LX471M450A452 provides 450 V rating with identical 470 µF capacitance and 3000-hour lifetime. This upgrade option is suitable where system voltage headroom justifies the increased physical height (1.850" vs. 1.772").

Compliance Considerations:

All recommended active-status substitutes carry ROHS3 compliance. The original ECO-S2GP471EA is REACH Affected; verify REACH compliance requirements for your application before final selection.

Frequently Asked Questions (FAQ)

Q: Can I use a 450 V rated capacitor in place of the 400 V ECO-S2GP471EA?

A: Yes. The 380LX471M450A452 is a valid upgrade option. Higher voltage rating provides additional safety margin. Verify that the increased height (1.850" vs. 1.772") fits within your mechanical constraints.

Q: What is the difference between the Rubycon 400USG470MEFC35X30 and 400USG470MEFCSN35X30?

A: Both are 470 µF, 400 V snap-in capacitors with identical electrical specifications. The primary difference is RoHS compliance: 400USG470MEFC35X30 is RoHS non-compliant, while 400USG470MEFCSN35X30 is ROHS3 compliant. For new designs, select the ROHS3 variant.

Q: Why does the B43501A9477M000 show "Not For New Designs" status?

A: This designation indicates the manufacturer has discontinued active support for new applications. Although the part offers superior ESR (140 mOhm) and extended lifetime (10000 hours), it should not be selected for new production. Use only for legacy system maintenance where no alternative exists.

Q: How do I verify physical fit when substituting capacitors with different heights?

A: The ECO-S2GP471EA has a maximum seated height of 1.772" (45.00 mm). Substitute parts range from 1.260" to 1.850" in height. Measure clearance above the component location on your PCB. Taller parts (SLPX471M400H7P3 at 1.575", 380LX471M450A452 at 1.850") require verification of available vertical space. Shorter parts (380LQ471M400A022, 400USG470MEFC35X30, 400USG470MEFCSN35X30 at 1.260") present no height constraint issues.

Q: What does ESR (Equivalent Series Resistance) indicate for capacitor selection?

A: ESR affects ripple current handling and heat dissipation. Lower ESR values indicate better high-frequency performance. The ECO-S2GP471EA specifies 388 mOhm @ 120Hz. Substitutes range from 140 mOhm (B43501A9477M000) to 705 mOhm (ESMM401VSN471MA35S, ESMM401VSN471MA35W). For applications with high ripple current or stringent thermal requirements, prioritize lower ESR values.

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

A: Yes. All listed substitutes maintain the radial, can snap-in package with 0.394" (10.00 mm) lead spacing and through-hole mounting. Packaging format (Bulk, Tray, or unspecified) does not affect electrical or mechanical compatibility.
