Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MALSECL00AD233FARK is determined by strict equivalence across the following parameters:

Core Electrical Requirements:

• Capacitance: 33 µF (exact match required)
• Voltage Rating: 35 V (minimum, equal or higher acceptable)
• Tolerance: ±20% (matching tolerance band)
• Polarization: Polar (electrolytic type)

Performance Characteristics:

• ESR and impedance values must support the same ripple current handling and frequency response
• Lifetime rating at 105°C must meet or exceed 2000 hours
• Operating temperature range must encompass -40°C to 105°C minimum

Physical & Mechanical Compatibility:

• Package Type: Radial, Can - SMD (surface mount configuration)
• Diameter: 6.30 mm (0.248")
• Height: Must not exceed available board clearance; substitute heights within ±0.050" are acceptable
• Surface Mount Land Size: 6.60 mm x 6.60 mm footprint compatibility required

Regulatory & Environmental:

• RoHS3 Compliance mandatory
• MSL 1 (Unlimited moisture sensitivity) required
• REACH Unaffected status required

The two substitute parts listed below meet all core electrical and mechanical requirements while offering improved performance characteristics in active production status.

Parameter Comparison

Engineering Selection Recommendations

336AXZ035M (Direct Equivalent): This part provides direct functional equivalence to the MALSECL00AD233FARK with active production status. The AXZ series maintains identical capacitance, voltage rating, and tolerance specifications. Physical dimensions are compatible with identical diameter and reduced height (5.60 mm vs. 6.10 mm), providing improved board clearance. The extended operating temperature range (-55°C to 105°C) exceeds the original specification. This part is suitable for direct substitution in applications where the original component is no longer available.

ATB336M035 (Upgrade Alternative): The ATB series represents an enhanced alternative with extended lifetime rating of 3000 hours at 105°C, compared to 2000 hours for the original part. This provides 50% greater thermal endurance. The ATB336M035 maintains all core electrical parameters while offering improved ripple current handling at 120 Hz (168 mA vs. 135.7 mA). Height remains compatible at 5.70 mm. The surface mount land size is slightly wider (7.10 mm vs. 6.60 mm), requiring verification of PCB layout compatibility. This part is recommended for applications requiring extended operational life or higher ripple current capacity.

Both substitute parts carry ROHS3 compliance, MSL 1 rating, and REACH Unaffected status, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can the 336AXZ035M be used as a direct drop-in replacement for the MALSECL00AD233FARK?

A: Yes. Both parts share identical capacitance (33 µF), voltage rating (35 V), tolerance (±20%), and surface mount package configuration. The 336AXZ035M has a reduced height (5.60 mm vs. 6.10 mm), which improves board clearance compatibility. The identical surface mount land size (6.60 mm x 6.60 mm) ensures PCB footprint compatibility.

Q: What is the difference between the 336AXZ035M and ATB336M035?

A: Both are functionally equivalent to the original part. The primary differences are: (1) ATB336M035 offers extended lifetime of 3000 hours at 105°C versus 2000 hours for the AXZ series; (2) ATB336M035 provides higher ripple current capacity at 120 Hz (168 mA vs. 115 mA); (3) ATB336M035 has a slightly wider surface mount land size (7.10 mm vs. 6.60 mm width), requiring PCB layout verification.

Q: Are there any height restrictions when substituting these parts?

A: The original MALSECL00AD233FARK has a seated height of 6.10 mm. Both substitute parts are shorter (336AXZ035M at 5.60 mm, ATB336M035 at 5.70 mm), providing improved clearance. Height reduction of 0.40-0.50 mm is within acceptable mechanical tolerances for surface mount applications and does not create compatibility issues.

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

A: Yes. Both 336AXZ035M and ATB336M035 are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and have REACH Unaffected status, matching the original component's regulatory profile.

Q: What is the impact of the wider surface mount land size on the ATB336M035?

A: The ATB336M035 has a surface mount land size of 6.60 mm x 7.10 mm (width increased by 0.50 mm compared to 6.60 mm x 6.60 mm). This requires verification that the PCB layout provides sufficient space for the wider footprint. If board space is constrained, the 336AXZ035M with standard 6.60 mm x 6.60 mm land size is the preferred alternative.

Q: Which substitute part should be selected for new designs?

A: For new designs requiring extended operational life or higher ripple current capacity, the ATB336M035 is recommended, provided PCB layout accommodates the 7.10 mm width. For applications with standard performance requirements and space constraints, the 336AXZ035M provides direct equivalence with improved height characteristics.
