Engineering Selection Recommendations

The PL2G331MND3030Y and 400MXH330MEFCSN30X30 are direct electrical and mechanical equivalents. Both parts are active products with ROHS3 compliance certification. Selection between these parts is determined by availability and supply chain requirements rather than technical performance differences.

The Rubycon 400MXH330MEFCSN30X30 currently maintains higher inventory availability (1339 pieces) compared to the Chinsan PL2G331MND3030Y (822 pieces), making it a viable alternative for procurement planning and production scheduling.

Both parts satisfy identical electrical specifications, thermal ratings, and mechanical mounting requirements for general-purpose aluminum electrolytic capacitor applications in 400 V circuits.

Frequently Asked Questions (FAQ)

Q: Can the 400MXH330MEFCSN30X30 be used as a direct replacement for the PL2G331MND3030Y?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical capacitance (330 µF), voltage rating (400 V), tolerance (±20%), thermal lifetime (2000 Hrs @ 105°C), operating temperature range (-25°C ~ 105°C), and physical dimensions (1.181" diameter, 1.260" height, 0.394" lead spacing). Both are snap-in radial through-hole packages with ROHS3 compliance.

Q: Are there any differences in ripple current ratings between these parts?

A: Minor differences exist in ripple current specifications. The Rubycon 400MXH330MEFCSN30X30 provides 1.55 A @ 120 Hz compared to 1.49 A @ 120 Hz for the Chinsan PL2G331MND3030Y. These variations remain within acceptable operating parameters for general-purpose applications and do not affect substitution eligibility.

Q: Do both parts have identical physical dimensions for PCB mounting?

A: Yes. Both parts have identical lead spacing (0.394" / 10.00 mm), diameter (1.181" / 30.00 mm), and maximum seated height (1.260" / 32.00 mm). They are mechanically interchangeable for through-hole snap-in mounting on PCBs designed for either part.

Q: What compliance certifications apply to both parts?

A: Both the PL2G331MND3030Y and 400MXH330MEFCSN30X30 are ROHS3 compliant. The Rubycon part carries additional REACH Unaffected certification. Both parts are classified under ECCN EAR99 for export purposes.

Q: Are there inventory considerations for selecting between these parts?

A: The Rubycon 400MXH330MEFCSN30X30 has 1339 pieces in stock, while the Chinsan PL2G331MND3030Y has 822 pieces available. For applications requiring immediate availability or larger production volumes, the Rubycon part offers greater stock depth.
