Substitute Part Grouping Explanation

Substitution for the B41868W5338M is based on the following critical parameters:

Capacitance Value: 3300 µF (exact match required)
Voltage Rating: Minimum 25 V (equal or higher voltage rating acceptable)
Package Dimensions: Lead spacing 0.295" (7.50 mm), case diameter 0.709" (18.00 mm)
Mounting Configuration: Through-hole radial, can package
Polarization: Polar (electrolytic)
Compliance: RoHS3 compliant, automotive-rated

Two substitute parts meet these criteria: B41896C5338M000 from EPCOS - TDK Electronics and MAL214650332E3 from Vishay Beyschlag/Draloric/BC Components. Both maintain identical capacitance, tolerance, lead spacing, and case diameter specifications. The B41896C5338M000 operates at the same 25 V rating, while MAL214650332E3 provides a higher 35 V rating, offering additional voltage margin in the application circuit.

Engineering Selection Recommendations

B41896C5338M000 is the primary substitute from the same manufacturer (EPCOS - TDK Electronics). This part maintains identical electrical specifications at 25 V rating and is actively produced. It carries AEC-Q200 automotive qualification and ROHS3 compliance. The reduced case height (1.319" vs. 1.654") provides improved PCB layout flexibility. Higher ripple current capability (4.6 A vs. 2.325 A) and lower impedance (21 mOhms vs. 28 mOhms) offer enhanced performance margins.

MAL214650332E3 from Vishay Beyschlag/Draloric/BC Components is an alternative substitute with identical capacitance and lead spacing. The 35 V voltage rating provides additional voltage margin compared to the original 25 V specification. This part is actively produced with AEC-Q200 qualification and ROHS3 compliance. Case height (1.378") and impedance (19 mOhms) fall between the original and primary substitute specifications.

Both substitutes are physically compatible with the original B41868W5338M footprint and meet automotive application requirements through active production status and relevant certifications.

Frequently Asked Questions (FAQ)

Q: Can B41896C5338M000 be used as a direct replacement for B41868W5338M?

A: Yes. Both parts share identical capacitance (3300 µF), voltage rating (25 V), tolerance (±20%), lead spacing (0.295"), and case diameter (0.709"). The primary difference is reduced case height (1.319" vs. 1.654"), which improves PCB layout compatibility. Both are through-hole radial, can packages with polar electrolytic construction.

Q: What is the advantage of using MAL214650332E3 over B41896C5338M000?

A: MAL214650332E3 provides a higher voltage rating (35 V vs. 25 V), offering additional voltage margin in the application circuit. It maintains identical capacitance, lead spacing, and case diameter. The impedance is lower (19 mOhms vs. 21 mOhms), providing slightly better high-frequency performance. Both are actively produced with automotive certifications.

Q: Are there height restrictions when substituting these parts?

A: The substitute parts have reduced heights compared to the original B41868W5338M. B41896C5338M000 measures 1.319" (34.60 mm) and MAL214650332E3 measures 1.378" (35.00 mm), versus the original 1.654" (42.00 mm). Verify PCB clearance requirements before selection, as reduced height may affect component placement in confined spaces.

Q: Do the substitute parts meet automotive compliance requirements?

A: Yes. Both B41896C5338M000 and MAL214650332E3 carry AEC-Q200 automotive qualification and ROHS3 compliance, meeting automotive application standards.

Q: What is the difference in ripple current capability?

A: B41896C5338M000 supports 4.6 A ripple current at 100 kHz, compared to 2.325 A for the original B41868W5338M. MAL214650332E3 supports 3.1 A at 100 kHz. Higher ripple current capability provides improved thermal performance under AC stress conditions.

Q: Can these parts be used interchangeably in the same circuit?

A: Yes, provided PCB layout accommodates the reduced heights of the substitute parts. Lead spacing (0.295") and case diameter (0.709") are identical across all three parts, ensuring mechanical compatibility. Electrical parameters (capacitance, tolerance, voltage rating) are equivalent or superior in the substitutes.
