Substitute Part Grouping Explanation

Substitute parts for the 380LX151M350H032 are classified into two categories based on electrical and mechanical compatibility:

Upgrade Substitutes maintain identical capacitance (150 µF), tolerance (±20%), package type (Radial, Can - Snap-In), lead spacing (10.00 mm), and mounting configuration (Through Hole). These parts differ in voltage rating (400 V, 420 V, or 450 V) and thermal performance specifications. Upgrade substitutes are direct replacements in applications where the circuit can tolerate higher voltage ratings and improved thermal characteristics.

Similar Substitutes match the original part in capacitance, tolerance, package type, lead spacing, and mounting, but operate at the same 350 V voltage rating with different thermal performance or physical height. These parts are functionally equivalent for circuits designed specifically for 350 V operation.

Engineering Selection Recommendations

For Direct Replacement (Same Voltage Rating): The ESMQ351VSN151MP25S (Chemi-Con SMQ series) is a similar substitute operating at 350 V with identical capacitance and tolerance. This part differs in physical height (25.00 mm versus 37.00 mm) and thermal performance (2000 Hrs @ 85°C versus 3000 Hrs @ 85°C). Selection of this part requires verification that the reduced height accommodates PCB layout constraints and that the lower thermal rating meets application lifetime requirements.

For Voltage Upgrade Applications: When circuit design permits higher voltage operation, the following upgrade substitutes are available:

400MXG150MEFCSN22X35 (Rubycon MXG): 400 V rating with extended operating temperature to 105°C. Maintains 3000 Hrs @ 105°C thermal rating.
420VXH150MEFCSN22X35 (Rubycon VXH): 420 V rating with 5000 Hrs @ 105°C thermal performance. Identical physical dimensions to the original part.
450MXG150MEFCSN22X35 (Rubycon MXG): 450 V rating with 3000 Hrs @ 105°C thermal performance. Highest voltage option with standard thermal rating.
450VXH150MEFCSN22X35 (Rubycon VXH): 450 V rating with extended 5000 Hrs @ 105°C thermal performance. Highest voltage and thermal rating combination.
ELXS421VSN151MP35S (Chemi-Con LXS): 420 V rating with 5000 Hrs @ 105°C. Physical height is 37.50 mm (0.50 mm taller than original). RoHS3 compliant.
LGX2G151MELZ35 (Nichicon LGX): 400 V rating with 5000 Hrs @ 105°C thermal performance. Identical physical dimensions to the original part.
LQSW6151MELZ35 (Nichicon LQS): 420 V rating with 3000 Hrs @ 105°C thermal performance. Identical physical dimensions to the original part.

All upgrade substitutes maintain RoHS3 compliance and are Active status products. Selection between upgrade options depends on circuit voltage tolerance, thermal environment, and required operational lifetime.

Frequently Asked Questions (FAQ)

Q: Can the 380LX151M350H032 be replaced with a higher voltage-rated capacitor?

A: Yes. Higher voltage-rated capacitors (400 V, 420 V, or 450 V) are direct mechanical and electrical substitutes provided the circuit design permits operation at the elevated voltage. All upgrade substitutes maintain identical capacitance (150 µF), tolerance (±20%), package type (Radial, Can - Snap-In), lead spacing (10.00 mm), and mounting configuration (Through Hole). The circuit must be designed to tolerate the higher voltage without adverse effects.

Q: What is the difference between the Rubycon MXG and VXH series substitutes?

A: Both series are manufactured by Rubycon and maintain identical physical dimensions and lead spacing. The primary difference is thermal performance: MXG series parts are rated for 3000 Hrs @ 105°C, while VXH series parts are rated for 5000 Hrs @ 105°C. Selection depends on application lifetime requirements and thermal environment.

Q: Are all substitute parts RoHS3 compliant?

A: All upgrade substitutes (400MXG150MEFCSN22X35, 420VXH150MEFCSN22X35, 450MXG150MEFCSN22X35, 450VXH150MEFCSN22X35, ELXS421VSN151MP35S, LGX2G151MELZ35, LQSW6151MELZ35) are RoHS3 compliant. The similar substitute ESMQ351VSN151MP25S is RoHS compliant but not RoHS3 certified.

Q: Does the ELXS421VSN151MP35S fit in the same PCB footprint?

A: The ELXS421VSN151MP35S has a maximum seated height of 37.50 mm compared to 37.00 mm for the original part. This 0.50 mm difference may affect PCB layout in space-constrained applications. Lead spacing (10.00 mm) and diameter (22.00 mm) are identical, ensuring mechanical compatibility with the through-hole footprint.

Q: What is the difference between the original 380LX151M350H032 and the ESMQ351VSN151MP25S?

A: Both parts operate at 350 V with 150 µF capacitance and ±20% tolerance. The ESMQ351VSN151MP25S differs in physical height (25.00 mm versus 37.00 mm) and thermal performance (2000 Hrs @ 85°C versus 3000 Hrs @ 85°C). The reduced height may be advantageous in space-constrained designs, but the lower thermal rating requires verification for application lifetime requirements.

Q: Can I use a 420 V substitute in a circuit designed for 350 V operation?

A: Yes. A 420 V capacitor can be used in a 350 V circuit because the capacitor is rated for higher voltage than the circuit requires. This provides additional safety margin. However, the circuit must be designed to tolerate the capacitor's operating temperature range (-25°C ~ 105°C for upgrade substitutes versus -25°C ~ 85°C for the original part).

Q: Which substitute offers the best thermal performance?

A: The 450VXH150MEFCSN22X35 and 420VXH150MEFCSN22X35 (Rubycon VXH series) and ELXS421VSN151MP35S (Chemi-Con LXS) all offer 5000 Hrs @ 105°C thermal performance, the highest available among the substitutes. The 450VXH150MEFCSN22X35 combines this thermal rating with the highest voltage rating (450 V).

Q: Are there inventory considerations for substitute selection?

A: Inventory levels vary by part number. The 450MXG150MEFCSN22X35 has the highest inventory (1,000,300 Pcs), while other substitutes range from 827 to 3,872 Pcs. Inventory availability should be confirmed with the supplier for production requirements.
