Parameter Comparison

Engineering Selection Recommendations

381LX471M200K012 (Cornell Dubilier Electronics)

This substitute part is recommended for new designs and ongoing production. The 381LX series maintains full electrical and mechanical compatibility with the 477LBB200M2DC. The extended operating temperature range (-40°C ~ 105°C) and higher temperature lifetime rating (3000 Hrs @ 105°C) provide enhanced thermal performance compared to the primary part. Both parts are manufactured by Cornell Dubilier, ensuring consistent quality and reliability. The 381LX471M200K012 is actively produced and widely available with 14,383 pieces in stock.

B43504F2477M000 (EPCOS - TDK Electronics)

This substitute part meets all mandatory electrical, mechanical, and compliance requirements. The B43504 series offers lower ESR (270 mOhm @ 100Hz) compared to the primary part (352.74 mOhm @ 120Hz), which may provide performance benefits in applications sensitive to impedance characteristics. However, this part carries a "Not For New Designs" product status, indicating that EPCOS - TDK Electronics is discontinuing this series. The B43504F2477M000 should be used only for replacement or maintenance of existing equipment. Limited inventory (918 pieces) is available.

Product Status Consideration:

For new designs, the 381LX471M200K012 is the preferred substitute. The B43504F2477M000 is suitable only for legacy system support or direct replacement scenarios where the original part is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the 381LX471M200K012 be used as a direct replacement for the 477LBB200M2DC?

A: Yes. Both parts share identical capacitance (470 µF), voltage rating (200 V), tolerance (±20%), physical dimensions (1.181" Dia × 1.063" Height), lead spacing (0.394"), and mounting configuration (radial, can-style snap-in through-hole). Both are ROHS3 compliant with MSL 1 rating. The 381LX series offers extended temperature performance, making it suitable for direct substitution in all applications.

Q: What is the difference between the 477LBB200M2DC and 381LX471M200K012 in terms of thermal performance?

A: The 477LBB200M2DC is rated for 3000 hours at 85°C with an operating temperature range of -40°C to 85°C. The 381LX471M200K012 is rated for 3000 hours at 105°C with an operating temperature range of -40°C to 105°C. The 381LX series provides superior thermal stability and extended operational capability at elevated temperatures.

Q: Why is the B43504F2477M000 marked as "Not For New Designs"?

A: The "Not For New Designs" status indicates that EPCOS - TDK Electronics has discontinued this product line. While the part remains functionally compatible and available in limited quantities, it should not be specified for new product development. Use this part only for replacement or maintenance of existing systems already using the B43504 series.

Q: Are there any differences in ripple current ratings between the substitute parts?

A: Yes. The 477LBB200M2DC supports 2.21 A @ 120 Hz and 3.2487 A @ 10 kHz. The 381LX471M200K012 supports 1.4 A @ 120 Hz and 2 A @ 20 kHz. The B43504F2477M000 supports 1.5 A @ 100 Hz. Applications requiring high ripple current handling should verify that the substitute part meets the specific ripple current requirements at the operating frequency.

Q: Do all three parts have the same physical footprint?

A: Yes. All three parts have identical physical dimensions: 1.181" diameter, 1.063" maximum seated height, and 0.394" lead spacing. They are all packaged as radial, can-style snap-in components with through-hole mounting. PCB layout and mechanical mounting are fully interchangeable.

Q: What is the ESR difference between the primary part and substitutes?

A: The 477LBB200M2DC has an ESR of 352.74 mOhm @ 120Hz. The B43504F2477M000 has an ESR of 270 mOhm @ 100Hz, offering lower impedance. The 381LX471M200K012 does not specify ESR. Applications sensitive to ESR characteristics should evaluate whether the lower impedance of the B43504 series provides performance benefits or whether the unspecified ESR of the 381LX series is acceptable.

Q: Are all parts RoHS3 compliant?

A: Yes. The 477LBB200M2DC, 381LX471M200K012, and B43504F2477M000 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status.
