Key Parameters

Substitute Part Grouping Explanation

Substitution logic is based on strict parameter matching within the following categories:

Critical Matching Parameters (Non-Negotiable):

• Capacitance: 220 µF
• Tolerance: ±20%
• Lead Spacing: 10.00 mm
• Size / Dimension: 22.00 mm diameter
• Package / Case: Radial, Can - Snap-In
• Mounting Type: Through Hole

Voltage Rating Substitution Rule: Substitute parts must have rated voltage equal to or greater than 350 V. Parts rated at 350 V are direct equivalents. Parts rated at 400 V or 420 V are upgrades and provide enhanced voltage margin.

Performance Parameters (Application-Dependent):

• Operating Temperature Range
• Lifetime @ Temperature
• ESR (Equivalent Series Resistance)
• Ripple Current ratings

Compliance Parameters:

• RoHS Status: ROHS3 Compliant or RoHS Compliant
• REACH Status: REACH Unaffected
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts are grouped into two categories:

Direct Substitutes (350 V Rating):

• 381LQ221M350H032 (CDE)
• LLS2V221MELZ (Nichicon)
• LGN2V221MELZ35 (Nichicon)

Upgrade Substitutes (400 V or Higher Rating):

• B43640E9227M000 (EPCOS - TDK Electronics) - 400 V
• ESMR401VSN221MP35S (Chemi-Con) - 400 V
• ESMR421VSN221MP35S (Chemi-Con) - 420 V

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Same Voltage Rating - 350 V):

The 381LQ221M350H032 from CDE is a direct substitute with identical electrical and mechanical specifications. This part offers improved ESR performance (754 mOhm vs. 900 mOhm) and extended operating temperature range (-25°C to 105°C vs. -25°C to 85°C). Both parts maintain ROHS3 compliance and identical form factor.

The LLS2V221MELZ from Nichicon is a direct substitute with matching 350 V rating and identical mechanical dimensions. This part provides extended lifetime rating (3000 Hrs @ 85°C vs. 2000 Hrs @ 85°C) while maintaining the same operating temperature range as the original part. ROHS3 compliance is maintained.

The LGN2V221MELZ35 from Nichicon is a direct substitute with matching 350 V rating and identical mechanical dimensions. This part offers extended lifetime (3000 Hrs @ 105°C) and expanded operating temperature range (-25°C to 105°C). ROHS3 compliance is maintained.

Upgrade Substitution (Higher Voltage Rating - 400 V or 420 V):

The B43640E9227M000 from EPCOS - TDK Electronics provides a 400 V rated upgrade with superior ESR performance (500 mOhm @ 100Hz) and extended operating temperature range (-40°C to 105°C). Mechanical dimensions remain identical. ROHS3 compliance is maintained.

The ESMR401VSN221MP35S from Chemi-Con provides a 400 V rated upgrade with identical mechanical dimensions. Height is marginally increased (37.50 mm vs. 37.00 mm). RoHS compliance is maintained.

The ESMR421VSN221MP35S from Chemi-Con provides a 420 V rated upgrade with identical mechanical dimensions. Height is marginally increased (37.50 mm vs. 37.00 mm). RoHS compliance is maintained.

Selection Criteria:

• All substitute parts maintain Active product status
• All substitute parts are ROHS3 Compliant or RoHS Compliant
• All substitute parts maintain REACH Unaffected status
• All substitute parts maintain Moisture Sensitivity Level 1 (Unlimited)
• Mechanical compatibility is confirmed for all listed substitutes
• Voltage rating upgrades provide enhanced circuit protection margin

Frequently Asked Questions (FAQ)

Q: Can I use a 400 V or 420 V rated capacitor in place of the 350 V original part?

A: Yes. Higher voltage-rated capacitors are electrically compatible substitutes. The 400 V and 420 V rated parts (B43640E9227M000, ESMR401VSN221MP35S, ESMR421VSN221MP35S) provide enhanced voltage margin and are mechanically identical or compatible with the original 380LQ221M350H032. These are classified as upgrade substitutes.

Q: What is the difference between direct substitutes and upgrade substitutes?

A: Direct substitutes maintain the same 350 V voltage rating as the original part (381LQ221M350H032, LLS2V221MELZ, LGN2V221MELZ35). Upgrade substitutes have higher voltage ratings (400 V or 420 V) and provide additional circuit protection margin while maintaining all other critical parameters.

Q: Are all substitute parts mechanically compatible with the original PCB layout?

A: Yes. All listed substitute parts maintain the critical mechanical parameters: 10.00 mm lead spacing, 22.00 mm diameter, radial can snap-in package, and through-hole mounting type. Two Chemi-Con parts (ESMR401VSN221MP35S, ESMR421VSN221MP35S) have a maximum seated height of 37.50 mm compared to 37.00 mm for the original part. This 0.50 mm difference must be verified against specific PCB clearance requirements.

Q: What does ROHS3 Compliant mean, and are all substitutes compliant?

A: ROHS3 Compliant indicates compliance with the Restriction of Hazardous Substances Directive 3. The original part and most direct substitutes (381LQ221M350H032, LLS2V221MELZ, LGN2V221MELZ35, B43640E9227M000) are ROHS3 Compliant. The Chemi-Con parts (ESMR401VSN221MP35S, ESMR421VSN221MP35S) are RoHS Compliant, which satisfies regulatory requirements.

Q: Which substitute offers the best ESR performance?

A: The B43640E9227M000 from EPCOS - TDK Electronics offers the lowest ESR at 500 mOhm @ 100Hz, compared to 900 mOhm @ 120Hz for the original part. The 381LQ221M350H032 from CDE offers 754 mOhm @ 120Hz. Lower ESR reduces heat generation and improves ripple current handling capability.

Q: Which substitute offers the longest operational lifetime?

A: The LLS2V221MELZ and LGN2V221MELZ35 from Nichicon both offer 3000 Hrs @ 85°C and 3000 Hrs @ 105°C respectively, compared to 2000 Hrs @ 85°C for the original part. Extended lifetime ratings indicate improved reliability for long-term applications.

Q: Can I use these substitutes in high-temperature applications above 85°C?

A: Yes. The 381LQ221M350H032, LGN2V221MELZ35, and B43640E9227M000 support operating temperatures up to 105°C. The B43640E9227M000 extends to -40°C minimum temperature. The original 380LQ221M350H032 and LLS2V221MELZ are limited to 85°C maximum. Application temperature requirements must be verified before selection.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in Bulk packaging with radial, can snap-in configuration suitable for through-hole PCB assembly. Inventory availability varies by part number and manufacturer.
