Substitute Part Grouping Explanation

Substitution of the MALSECV00AE233FARK is determined by strict equivalence across the following critical parameters:

• Capacitance value: 33 µF (exact match required)
• Voltage rating: 35 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting type: Surface Mount (exact match required)
• Package style: Radial, Can - SMD (exact match required)
• Physical dimensions: Compatible with 0.315" diameter and maximum height constraints
• Compliance: ROHS3 and REACH status alignment

The substitute part MAL215370339E3 meets all critical electrical and mechanical parameters while offering improved performance characteristics in ESR and lifetime rating.

Parameter Comparison

Engineering Selection Recommendations

MAL215370339E3 is a direct functional substitute for MALSECV00AE233FARK. Both components maintain identical electrical specifications for capacitance, voltage rating, and tolerance. The substitute part carries Last Time Buy status, indicating controlled availability, while the original part is obsolete.

The substitute demonstrates improved performance metrics: reduced ESR (1.2 Ohm @ 100 kHz versus 5.22 Ohm @ 120 Hz), extended lifetime (3000 hours versus 2000 hours at 105°C), and increased ripple current capability (110 mA @ 100 Hz versus 76 mA @ 120 Hz). Physical dimensions remain compatible with existing PCB layouts, with the substitute part featuring a slightly reduced seated height (6.50 mm versus 6.60 mm).

Both components maintain equivalent compliance certifications: ROHS3 compliant, REACH unaffected, and MSL 1 rating. Packaging differs between the original (unspecified) and substitute (Tape & Reel), which affects procurement and assembly processes but not electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can MAL215370339E3 be used as a direct replacement for MALSECV00AE233FARK in existing designs?

A: Yes. Both parts share identical capacitance (33 µF), voltage rating (35 V), tolerance (±20%), polarization, and surface mount package style. Physical dimensions are compatible, with the substitute featuring a marginally smaller seated height that poses no layout constraints.

Q: What are the key differences between these two parts?

A: The substitute part offers improved electrical performance with lower ESR and higher ripple current capability, plus extended operational lifetime at rated temperature. The substitute is available in Tape & Reel packaging, whereas the original part packaging is unspecified. Both maintain identical compliance certifications.

Q: Does the lower ESR of MAL215370339E3 affect circuit behavior?

A: Lower ESR generally reduces impedance and heat generation in the capacitor. For general-purpose applications, this represents an improvement. Circuit-specific performance depends on application requirements and operating conditions.

Q: Are there any physical installation differences?

A: No. Both components use identical surface mount package styles and case dimensions. The substitute part is 0.1 mm shorter in seated height, which does not create installation conflicts.

Q: What is the significance of Last Time Buy status for MAL215370339E3?

A: Last Time Buy indicates the manufacturer has announced controlled availability with a defined cutoff date for new orders. This differs from obsolete status but signals that long-term supply cannot be guaranteed. Procurement planning should account for this status.

Q: Are compliance certifications equivalent?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) ratings. Regulatory and environmental compliance requirements are met by either component.
