Engineering Selection Recommendations

Direct Equivalent Selection (Preferred for Drop-In Replacement):

The EPCOS - TDK Electronics B43508 series (B43508A9227M000, B43508A9227M002, B43508A9227M62, B43508A9227M67, B43508A9227M7, B43508A9227M80, B43508A9227M82, B43508A9227M87) provides direct electrical equivalence with improved performance characteristics. These parts maintain identical capacitance, voltage rating, tolerance, and mechanical dimensions while offering reduced ESR (560 mOhm @ 100 Hz versus 829 mOhm @ 120 Hz) and extended lifetime (3000 hours @ 105°C versus 2000 hours). All variants are ROHS3 compliant and carry active product status with substantial inventory availability.

The Cornell Dubilier Electronics 381LQ221M400H452 offers identical electrical specifications to the original part with matching ESR and lifetime ratings. This part is ROHS3 compliant and active. Note that the seated height is 1.850" (47.00 mm), which exceeds the original 1.654" (42.00 mm). Verify mechanical clearance in the application before selection.

Upgrade Substitute (Higher Voltage Margin):

The Rubycon 420MXH220MEFCSN22X40 provides a 420 V rated voltage, offering a 20 V margin above the original 400 V specification. This part maintains identical capacitance, tolerance, and mechanical dimensions. The higher ripple current capability (1.37 A @ 120 Hz) supports applications with increased current demands. ROHS3 compliance and active product status are confirmed. This selection is appropriate when enhanced voltage margin and ripple current handling are beneficial to system reliability.

Compliance Considerations:

All recommended substitutes are ROHS3 compliant. The original EET-HC2G221BF carries REACH Affected status, while all active substitutes are REACH Unaffected. All parts share identical ECCN (EAR99) and HTSUS (8532.22.0040) classifications.

Frequently Asked Questions (FAQ)

Q: Can the Cornell Dubilier 381LQ221M400H452 be used as a direct replacement despite the increased height?

A: The 381LQ221M400H452 has a seated height of 1.850" (47.00 mm) compared to the original 1.654" (42.00 mm). Electrical compatibility is confirmed, but mechanical clearance in the PCB layout and surrounding components must be verified before implementation.

Q: What is the advantage of selecting EPCOS B43508 variants over the original part?

A: The B43508 series delivers lower ESR (560 mOhm @ 100 Hz versus 829 mOhm @ 120 Hz), extended lifetime (3000 hours @ 105°C versus 2000 hours), and wider operating temperature range (-40°C to 105°C versus -25°C to 105°C). These improvements enhance thermal performance and system reliability without changing electrical or mechanical compatibility.

Q: When should the Rubycon 420MXH220MEFCSN22X40 upgrade be selected?

A: Select this part when the application benefits from higher voltage margin (420 V versus 400 V) or requires increased ripple current handling (1.37 A @ 120 Hz). The upgrade maintains identical mechanical fit and capacitance while providing enhanced performance headroom.

Q: Are all substitute parts through-hole mounted with identical lead spacing?

A: Yes. All recommended substitutes maintain 0.394" (10.00 mm) lead spacing and through-hole mounting type, ensuring PCB footprint compatibility with the original EET-HC2G221BF design.

Q: What is the inventory status of these substitutes?

A: All recommended parts carry active product status with confirmed new original stock availability: 381LQ221M400H452 (3323 pcs), B43508 variants (729-1128 pcs per variant), and 420MXH220MEFCSN22X40 (700 pcs).

Q: Do all substitutes meet RoHS compliance requirements?

A: All active substitute parts are ROHS3 compliant. The original EET-HC2G221BF does not specify RoHS status. Verify RoHS requirements for your specific application before final part selection.
