Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MALSECA00BD233FARK is determined by the following critical parameters:

Core Electrical Parameters (Non-Negotiable):

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

Physical Compatibility Parameters:

• Package Type: Radial, Can - SMD (surface mount configuration)
• Diameter: 0.248" (6.30mm) nominal
• Height: Within 0.220" ± tolerance (5.60mm nominal)
• Surface Mount Land Size: 0.260" L × 0.260" W (6.60mm × 6.60mm) or compatible footprint

Performance Parameters (Application-Dependent):

• ESR @ 120 Hz: 6.03 Ohm (reference baseline; higher values acceptable for general purpose applications)
• Ripple Current @ 120 Hz: 65 mA minimum (higher values provide margin)
• Operating Temperature: -40°C ~ 85°C minimum (extended ranges acceptable)
• Lifetime @ Temperature: 2000 Hrs @ 85°C minimum (longer lifetimes acceptable)

Compliance Parameters:

• RoHS3 Compliant (required for regulatory alignment)
• MSL 1 (Unlimited moisture sensitivity acceptable)

Substitute parts meeting all core electrical and physical parameters are classified as direct equivalents. Parts exceeding performance specifications (lower ESR, higher ripple current, extended temperature range, longer lifetime) are classified as upgrades.

Parameter Comparison

Engineering Selection Recommendations

336SML035M (Direct Equivalent): The 336SML035M from Cornell Dubilier / Illinois Capacitor is a direct functional equivalent meeting all core electrical specifications: 33 µF capacitance, ±20% tolerance, 35 V rating, and identical physical dimensions. This part is currently in active production status, ensuring supply chain availability. The ESR of 7.033 Ohm @ 120 Hz is marginally higher than the original 6.03 Ohm but remains within acceptable tolerance for general purpose applications. Ripple current handling is identical at 65 mA @ 120 Hz. This part is suitable for direct replacement in existing designs without circuit modification.

336AXZ035M (Performance Upgrade): The 336AXZ035M offers improved performance characteristics while maintaining physical compatibility. This part matches the original ESR specification at 6.03 Ohm @ 120 Hz and provides extended operating temperature range (-55°C ~ 105°C versus -40°C ~ 85°C). Ripple current capacity is significantly increased to 115 mA @ 120 Hz and 230 mA @ 100 kHz. Lifetime specification is maintained at 2000 Hrs @ 105°C. This part is suitable for applications requiring enhanced thermal performance or higher ripple current handling. Physical dimensions remain compatible with the original footprint.

ATB336M035 (Enhanced Upgrade): The ATB336M035 provides the highest performance specification among available substitutes. ESR is reduced to 5.63 Ohm @ 120 Hz, and ripple current capacity reaches 168 mA @ 120 Hz and 240 mA @ 100 kHz. Lifetime is extended to 3000 Hrs @ 105°C with operating temperature range of -55°C ~ 105°C. The surface mount land size is slightly modified to 0.260" L × 0.280" W (6.60mm × 7.10mm), requiring PCB footprint verification before implementation. This part is suitable for demanding applications with stringent thermal and ripple current requirements.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory alignment and moisture handling compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the 336SML035M be used as a direct drop-in replacement for the MALSECA00BD233FARK?

A: Yes. The 336SML035M meets all core electrical parameters (33 µF, ±20%, 35 V) and physical dimensions (0.248" diameter, 5.50mm height, 0.260" × 0.260" land size). The slightly higher ESR of 7.033 Ohm versus 6.03 Ohm is acceptable for general purpose applications. No circuit modification is required.

Q: What is the difference between the direct equivalent and upgrade parts?

A: The 336SML035M is a direct equivalent matching the original specifications. The 336AXZ035M and ATB336M035 are upgrades offering improved performance: lower ESR, higher ripple current capacity, extended temperature range, and longer lifetime. Upgrades are suitable for applications requiring enhanced performance but may not be necessary for all designs.

Q: Does the ATB336M035 require PCB layout changes?

A: The ATB336M035 has a modified surface mount land size of 0.260" L × 0.280" W (6.60mm × 7.10mm) compared to the original 0.260" L × 0.260" W (6.60mm × 6.60mm). PCB footprint compatibility must be verified before implementation. The physical diameter and height remain compatible.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (336SML035M, 336AXZ035M, ATB336M035) are ROHS3 compliant and maintain MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's regulatory status.

Q: Which substitute part should be selected for high-temperature applications?

A: Both upgrade parts (336AXZ035M and ATB336M035) support extended operating temperature range of -55°C ~ 105°C compared to the original -40°C ~ 85°C. The ATB336M035 provides the longest lifetime specification at 3000 Hrs @ 105°C, making it suitable for sustained high-temperature operation.

Q: What is the ripple current difference between substitute parts?

A: The 336SML035M matches the original at 65 mA @ 120 Hz. The 336AXZ035M provides 115 mA @ 120 Hz. The ATB336M035 offers the highest capacity at 168 mA @ 120 Hz. Selection depends on circuit ripple current requirements at the operating frequency.
