Substitute Part Grouping Explanation

Substitution for the EET-HC2W221BA is determined by strict equivalence across the following electrical and mechanical parameters:

Capacitance: 220 µF (exact match required)
Voltage Rating: 450 V (exact match required)
Tolerance: ±20% (exact match required)
Package Configuration: Radial, Can - Snap-In (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Case Diameter: 0.866" (22.00 mm) (exact match required)
Height - Seated (Max): 2.047" (52.00 mm) or 2.055" (52.20 mm) (within tolerance)
Mounting Type: Through Hole (exact match required)

All substitute parts listed meet these criteria. Direct substitutes from EPCOS - TDK Electronics (B43508 series) maintain identical electrical specifications with improved performance characteristics. The Rubycon MXG series represents an upgrade option with enhanced ripple current handling.

Engineering Selection Recommendations

EPCOS - TDK Electronics B43508A5227M Series (Direct Substitutes)

The B43508A5227M series provides direct electrical and mechanical equivalence to the EET-HC2W221BA. These parts are active products with ROHS3 compliance and offer improved performance metrics: reduced ESR (560 mOhm vs. 829 mOhm), extended lifetime (3000 hours vs. 2000 hours at 105°C), and wider operating temperature range (-40°C to 105°C). Multiple packaging variants are available (B43508A5227M000, B43508A5227M2, B43508A5227M60, B43508A5227M62, B43508A5227M67, B43508A5227M7, B43508A5227M80, B43508A5227M82, B43508A5227M87), all meeting identical electrical specifications. Selection among variants depends on procurement source and lead time requirements.

Rubycon 450MXG220MEFCSN22X50 (Upgrade Option)

The Rubycon MXG series represents an upgrade path with enhanced ripple current capability (1.49 A @ 120 Hz vs. 900 mA for the original part) and extended lifetime (3000 hours at 105°C). This part maintains identical mechanical dimensions and electrical ratings while providing superior performance headroom for applications requiring higher ripple current handling. ROHS3 compliance is confirmed.

Frequently Asked Questions (FAQ)

Q: Can the B43508A5227M series be used as a direct replacement for the EET-HC2W221BA?

A: Yes. The B43508A5227M series maintains identical capacitance (220 µF), voltage rating (450 V), tolerance (±20%), package configuration (radial, can - snap-in), lead spacing (0.394" / 10.00 mm), case diameter (0.866" / 22.00 mm), and mounting type (through hole). Physical dimensions are compatible within tolerance. All variants in this series are electrically equivalent.

Q: What is the difference between the various B43508A5227M part numbers?

A: All B43508A5227M variants (M000, M2, M60, M62, M67, M7, M80, M82, M87) share identical electrical specifications and physical dimensions. The suffix designations reflect different manufacturing dates or packaging configurations from EPCOS - TDK Electronics. Selection should be based on availability and procurement requirements.

Q: Does the Rubycon 450MXG220MEFCSN22X50 fit in the same PCB footprint?

A: Yes. The Rubycon part maintains the same lead spacing (0.394" / 10.00 mm), case diameter (0.866" / 22.00 mm), and height (2.047" / 52.00 mm). It is mechanically compatible with the original EET-HC2W221BA footprint.

Q: What are the compliance differences between substitute options?

A: Both the EPCOS B43508A5227M series and Rubycon 450MXG220MEFCSN22X50 are ROHS3 compliant and REACH unaffected. The original EET-HC2W221BA compliance status is not specified in available documentation.

Q: Are there performance advantages to using the Rubycon upgrade part?

A: The Rubycon 450MXG220MEFCSN22X50 provides higher ripple current capacity (1.49 A @ 120 Hz vs. 900 mA for the original) and extended thermal lifetime (3000 hours at 105°C). These characteristics make it suitable for applications with elevated ripple current demands while maintaining all other electrical and mechanical equivalence.

Q: What is the temperature operating range for each substitute?

A: The EPCOS B43508A5227M series operates from -40°C to 105°C, providing a wider low-temperature range than the original EET-HC2W221BA (-25°C to 105°C). The Rubycon part matches the original range (-25°C to 105°C).
