Substitute Part Grouping Explanation

Substitute parts for the SEK332M050ST are qualified based on the following mandatory electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Capacitance: 3300 µF (exact match required)
• Voltage Rating: 50 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)

Mechanical Compatibility Criteria:

• Package Type: Radial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.295" (7.50 mm) (exact match required)
• Diameter: 0.709" (18.00 mm) (exact match required)

Regulatory Compliance:

• RoHS3 Compliant (required)
• REACH Unaffected (required)

Two substitute parts meet these criteria: MAL215051332E3 (Vishay Beyschlag/Draloric/BC Components) and ECA-1HHG332 (Panasonic Electronic Components). Both parts maintain identical electrical specifications and mechanical form factors, ensuring direct functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

MAL215051332E3 (Vishay Beyschlag/Draloric/BC Components): This substitute part is qualified for applications requiring extended operational lifetime. The part carries AEC-Q200 automotive qualification, indicating compliance with automotive-grade reliability standards. The rated lifetime of 10000 hours at 105°C exceeds the original SEK332M050ST specification of 2000 hours at 105°C. This part is suitable for applications where enhanced reliability and extended service life are required. Height dimension is 1.673" (42.50 mm), representing a 0.019" (0.50 mm) increase over the original part.

ECA-1HHG332 (Panasonic Electronic Components): This substitute part maintains identical lifetime rating of 2000 hours at 105°C as the original SEK332M050ST. The part is suitable for general-purpose applications with equivalent performance characteristics. Height dimension is 1.476" (37.50 mm), representing a 0.178" (4.50 mm) reduction compared to the original part. This dimensional difference may provide space advantages in compact circuit board layouts.

Both substitute parts maintain full regulatory compliance (ROHS3 and REACH) and are classified as Active products with continuous manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can MAL215051332E3 be used as a direct replacement for SEK332M050ST?

A: Yes. The MAL215051332E3 maintains identical electrical specifications (3300 µF, 50 V, ±20% tolerance) and mechanical form factor (radial, can package, 0.295" lead spacing, 0.709" diameter). The height dimension differs by 0.50 mm (1.673" versus 1.654"), which is within typical PCB layout tolerances for through-hole components. Both parts are ROHS3 compliant and REACH unaffected.

Q: What is the primary difference between the two substitute parts?

A: The MAL215051332E3 offers extended lifetime rating of 10000 hours at 105°C compared to 2000 hours at 105°C for both the original SEK332M050ST and the ECA-1HHG332. The MAL215051332E3 carries AEC-Q200 automotive qualification. The ECA-1HHG332 has a reduced height dimension of 1.476" (37.50 mm) versus 1.654" (42.00 mm) for the original part.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: All three parts share identical lead spacing (0.295" / 7.50 mm) and diameter (0.709" / 18.00 mm), ensuring PCB footprint compatibility. Height variations are: SEK332M050ST at 1.654" (42.00 mm), MAL215051332E3 at 1.673" (42.50 mm), and ECA-1HHG332 at 1.476" (37.50 mm). These differences are within standard through-hole component tolerances and do not affect electrical performance or circuit functionality.

Q: Do all substitute parts meet the same regulatory requirements?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected. The MAL215051332E3 additionally carries AEC-Q200 automotive qualification, which is not required for general-purpose applications but indicates enhanced reliability screening.

Q: Which substitute part should be selected for automotive applications?

A: The MAL215051332E3 is qualified for automotive applications with AEC-Q200 certification and extended 10000-hour lifetime rating at 105°C. This part is suitable for automotive-grade reliability requirements.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided that PCB layout accommodates the height variations noted in the parameter comparison table. The electrical performance and mechanical mounting characteristics are equivalent across all three parts.
