Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B41858C8227M is determined by the following critical parameters:

• Capacitance value: 220 µF (exact match required)
• Voltage rating: 63 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can through-hole (exact match required)
• Physical dimensions: 0.394" diameter, 22.00mm height, 5.00mm lead spacing (exact match required)
• Operating temperature range: -55°C to 105°C (exact match required)
• Polarization: Polar (exact match required)

All substitute parts listed meet these core electrical and mechanical parameters. Differences in ESR, ripple current ratings, lifetime specifications, and product status are secondary considerations that do not affect basic substitutability but may influence application suitability.

Parameter Comparison

Engineering Selection Recommendations

B41888C8227M is a direct equivalent from the same manufacturer (EPCOS - TDK Electronics) with active product status. It maintains identical electrical specifications and physical dimensions while offering extended lifetime (7000 hours at 105°C versus 5000 hours) and AEC-Q200 automotive qualification. This part is the preferred substitute for applications requiring continued support from the original manufacturer.

MAL215058221E3 and MAL215068221E3 are functionally equivalent alternatives from Vishay Beyschlag/Draloric/BC Components. Both parts are active, ROHS3 compliant, and carry AEC-Q200 automotive ratings. They provide 6000-hour lifetime at 105°C and identical physical dimensions and electrical ratings. These parts are suitable for applications where cross-manufacturer substitution is acceptable.

Selection between substitute options should be based on supply chain availability, procurement lead times, and existing qualification status within the target application.

Frequently Asked Questions (FAQ)

Q: Can B41888C8227M be used as a direct replacement for B41858C8227M?

A: Yes. Both parts share identical capacitance (220 µF), voltage rating (63 V), tolerance (±20%), physical dimensions, lead spacing, and operating temperature range. B41888C8227M is active and carries AEC-Q200 qualification, making it the preferred EPCOS equivalent.

Q: Are the Vishay parts (MAL215058221E3 and MAL215068221E3) compatible with the original B41858C8227M?

A: Yes. Both Vishay parts meet all critical electrical and mechanical parameters: 220 µF capacitance, 63 V rating, ±20% tolerance, identical case size, lead spacing, and operating temperature range. Cross-manufacturer substitution is electrically and mechanically valid.

Q: What is the difference between MAL215058221E3 and MAL215068221E3?

A: Both parts are functionally identical in all provided specifications. They share the same capacitance, voltage, tolerance, lifetime, impedance, and physical dimensions. Selection between them should be based on inventory availability and procurement considerations.

Q: Does the extended lifetime of B41888C8227M (7000 hours) affect compatibility?

A: No. Extended lifetime is a performance enhancement that does not affect electrical or mechanical compatibility. The part remains a direct substitute with identical core specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. B41858C8227M, B41888C8227M, MAL215058221E3, and MAL215068221E3 are all ROHS3 compliant.

Q: Do the substitute parts carry automotive qualification?

A: B41888C8227M, MAL215058221E3, and MAL215068221E3 all carry AEC-Q200 automotive qualification. The original B41858C8227M does not specify AEC-Q200 rating in the provided data.
