Substitute Part Grouping Explanation

Substitution for the MALIEYN07LA433J42K is determined by strict equivalence across the following critical parameters:

• Capacitance value: 3300 µF (exact match required)
• Voltage rating: 63 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can - Snap-In (exact match required)
• Physical dimensions: 0.866" Dia (22.00mm) and 1.457" (37.00mm) height (exact match required)
• Mounting type: Through Hole (exact match required)
• Operating temperature range: -40°C ~ 85°C (exact match required)
• Polarization: Polar (exact match required)
• Regulatory compliance: ROHS3 Compliant (exact match required)

The LLS1J332MELZ from Nichicon meets all these criteria and qualifies as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The LLS1J332MELZ is the qualified equivalent substitute for the MALIEYN07LA433J42K. Selection of this substitute is supported by the following factors:

• Both parts maintain identical electrical specifications: 3300 µF capacitance, 63 V voltage rating, and ±20% tolerance.
• Physical dimensions and mounting characteristics are identical, ensuring direct PCB compatibility without layout modifications.
• Both parts comply with ROHS3 and REACH regulatory requirements, maintaining environmental and safety standards.
• The LLS1J332MELZ carries active product status, ensuring ongoing availability and supply chain continuity, whereas the original part is obsolete.
• Lead spacing of 0.394" (10.00mm) on the substitute part is compatible with standard through-hole PCB designs.

Frequently Asked Questions (FAQ)

Q: Can the LLS1J332MELZ be used as a direct replacement for the MALIEYN07LA433J42K without PCB modifications?

A: Yes. Both parts share identical physical dimensions (0.866" diameter, 1.457" height), lead spacing, and mounting type. Direct substitution on existing PCBs is possible without layout changes.

Q: Are there differences in electrical performance between these parts?

A: Both parts meet the same capacitance (3300 µF), voltage rating (63 V), and tolerance (±20%) specifications. The LLS1J332MELZ offers extended lifetime (3000 Hrs @ 85°C versus 2000 Hrs @ 85°C for the original), providing improved reliability.

Q: What is the significance of the obsolete status of the MALIEYN07LA433J42K?

A: Obsolete status indicates the part is no longer manufactured. The LLS1J332MELZ, with active product status, ensures continued availability for replacement and new production requirements.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the MALIEYN07LA433J42K and LLS1J332MELZ are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the lead spacing specification, and why is it important?

A: The LLS1J332MELZ has a lead spacing of 0.394" (10.00mm). This specification ensures compatibility with standard through-hole PCB pad layouts and snap-in mounting fixtures designed for radial capacitors in this form factor.
