Substitute Part Grouping Explanation

Substitution of the 336AVD050MEL is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Capacitance: 33 µF (exact match required)
• Voltage Rating: 50 V (minimum, no downrating permitted)
• Tolerance: ±20% (electrical tolerance band)
• Polarization: Polar (electrolytic type)
• Mounting Type: Surface Mount (PCB assembly compatibility)
• Package / Case: Radial, Can - SMD (physical form factor)
• Operating Temperature Range: -55°C to 105°C (thermal envelope)

Performance Parameters Evaluated for Substitution:

• ESR @ 120 Hz: Substitute values must not exceed the original specification to maintain circuit performance
• Ripple Current Ratings: Substitute values must meet or exceed the original specification
• Impedance: Lower impedance values indicate improved high-frequency performance
• Lifetime @ 105°C: Extended lifetime ratings provide enhanced reliability margin

The two substitute parts identified (336AXZ050M and ATB336M050) satisfy all mandatory equivalence criteria while offering variations in performance characteristics suitable for different application requirements.

Parameter Comparison

Engineering Selection Recommendations

336AXZ050M Selection Criteria:

The 336AXZ050M is an active product with ROHS3 compliance and identical physical dimensions to the 336AVD050MEL. ESR performance is equivalent (6.029 Ohm vs. 6.03 Ohm @ 120 Hz), and lifetime rating matches at 2000 hours @ 105°C. Ripple current ratings are slightly lower (85 mA @ 120 Hz vs. 92.5 mA; 170 mA @ 100 kHz vs. 185 mA), and impedance is marginally higher (800 mOhms vs. 680 mOhms). This substitute is suitable for applications where the original 336AVD050MEL footprint and performance envelope must be preserved with minimal design modification. The identical land size (0.260" L x 0.260" W) permits direct PCB layout compatibility.

ATB336M050 Selection Criteria:

The ATB336M050 is an active product with ROHS3 compliance and enhanced performance characteristics. ESR is reduced to 4.82 Ohm @ 120 Hz (20% improvement), and lifetime is extended to 5000 hours @ 105°C (2.5x improvement). Ripple current ratings are significantly higher (245 mA @ 120 Hz vs. 92.5 mA; 350 mA @ 100 kHz vs. 185 mA), and impedance is lower (500 mOhms vs. 680 mOhms). Physical dimensions are larger (0.315" Dia vs. 0.248" Dia; 0.413" Height vs. 0.307" Height), requiring PCB layout modification and land size adjustment (0.346" L x 0.335" W vs. 0.260" L x 0.260" W). This substitute is appropriate for designs requiring improved thermal performance, higher ripple current handling, or extended operational lifetime, provided PCB space permits the larger package footprint.

Both substitutes maintain the mandatory electrical specifications (33 µF, 50 V, ±20%, polar, surface mount, radial can SMD) and operating temperature range (-55°C to 105°C). Selection between 336AXZ050M and ATB336M050 depends on PCB layout constraints and application performance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 336AXZ050M be used as a direct replacement for the 336AVD050MEL without PCB modification?

A: Yes. The 336AXZ050M maintains identical physical dimensions (0.248" Dia, 0.307" Height) and surface mount land size (0.260" L x 0.260" W). No PCB layout changes are required for footprint compatibility. Electrical performance is equivalent across capacitance, voltage rating, tolerance, and operating temperature range.

Q: What are the limitations of the 336AXZ050M compared to the original 336AVD050MEL?

A: Ripple current ratings are slightly lower (85 mA @ 120 Hz vs. 92.5 mA; 170 mA @ 100 kHz vs. 185 mA), and impedance is marginally higher (800 mOhms vs. 680 mOhms). Lifetime rating is identical at 2000 hours @ 105°C. These differences are minor and suitable for most general-purpose applications.

Q: When should the ATB336M050 be selected instead of the 336AXZ050M?

A: The ATB336M050 should be selected when applications require higher ripple current handling (245 mA @ 120 Hz, 350 mA @ 100 kHz), lower ESR (4.82 Ohm), extended lifetime (5000 hours @ 105°C), or improved thermal performance. PCB layout must accommodate the larger package (0.315" Dia, 0.413" Height) and modified land size (0.346" L x 0.335" W).

Q: Are both substitute parts RoHS compliant?

A: Yes. Both 336AXZ050M and ATB336M050 are ROHS3 compliant. The original 336AVD050MEL does not specify RoHS status. Both substitutes meet current environmental and regulatory requirements for electronic component manufacturing and assembly.

Q: What is the moisture sensitivity level for these capacitors?

A: All three parts (336AVD050MEL, 336AXZ050M, and ATB336M050) have Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage, handling, or assembly.

Q: Can these capacitors be used interchangeably in bypass and decoupling applications?

A: The 336AXZ050M and ATB336M050 are specified for bypass and decoupling applications. The 336AVD050MEL is specified for general-purpose applications. All three maintain the electrical and thermal specifications required for bypass and decoupling circuits. Selection should be based on ripple current requirements and available PCB space.

Q: What is the difference in impedance between the three parts, and does it matter?

A: The 336AVD050MEL has 680 mOhms impedance, the 336AXZ050M has 800 mOhms, and the ATB336M050 has 500 mOhms. Lower impedance improves high-frequency performance and reduces voltage ripple. The ATB336M050 offers superior impedance characteristics; the 336AXZ050M impedance is slightly higher but remains acceptable for most applications.

Q: Are there any ECCN or HTSUS code differences between the parts?

A: All three parts share identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications, indicating no export control or tariff differences.
