227LMB250M2CC Equivalent & Substitute Parts

Part Overview

The 227LMB250M2CC is a 220 µF, 250 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring through-hole mounting. The part is currently active in production with 740 units in stock. Substitute parts are identified when original inventory becomes unavailable, when application requirements demand extended operational lifetime, or when design specifications allow for compatible alternatives meeting or exceeding the original electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution of the 227LMB250M2CC with the LGR2E221MELA25 is based on strict equivalence of the following critical parameters:

Electrical Equivalence:

• Capacitance: 220 µF (identical)
• Voltage Rating: 250 V (identical)
• Tolerance: ±20% (identical)
• Polarization: Polar (identical)

Mechanical Equivalence:

• Package Type: Radial, Can - Snap-In (identical)
• Lead Spacing: 0.394" (10.00mm) (identical)
• Diameter: 0.984" (25.00mm) (identical)
• Height: 1.063" (27.00mm) (identical)
• Mounting Type: Through Hole (identical)

Compliance Equivalence:

• RoHS3 Compliant (both parts)
• REACH Unaffected (both parts)
• ECCN: EAR99 (both parts)
• HTSUS: 8532.22.0040 (both parts)

The substitute part exceeds the original in operational lifetime (10,000 hours at 105°C versus 3,000 hours) and extends the lower operating temperature limit to -40°C. These enhancements do not compromise compatibility or introduce design conflicts.

Parameter Comparison

Engineering Selection Recommendations

Both the 227LMB250M2CC and LGR2E221MELA25 are active production parts with full RoHS3 compliance and REACH unaffected status. Selection between these parts is determined by application requirements and inventory availability.

The 227LMB250M2CC is the primary choice when original part specifications are required and inventory is available.

The LGR2E221MELA25 serves as a direct substitute when the 227LMB250M2CC is unavailable. The Nichicon part provides identical electrical and mechanical compatibility with extended operational lifetime at rated temperature (10,000 hours versus 3,000 hours at 105°C) and expanded lower temperature operating range (-40°C versus -25°C). These characteristics make the substitute suitable for applications requiring enhanced reliability or extended service life without design modification.

Both parts meet identical regulatory and compliance requirements, ensuring no additional certification or qualification burden in applications already approved for either manufacturer's aluminum electrolytic capacitors in this category.

Frequently Asked Questions (FAQ)

Q: Can the LGR2E221MELA25 be used as a direct replacement for the 227LMB250M2CC on existing circuit boards?

A: Yes. Both parts share identical capacitance (220 µF), voltage rating (250 V), tolerance (±20%), package type (radial, can-style snap-in), lead spacing (10.00mm), diameter (25.00mm), and height (27.00mm). Through-hole mounting compatibility is identical. No circuit board redesign or rework is required.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Cornell Dubilier versus Nichicon), operational lifetime at 105°C (3,000 hours versus 10,000 hours), and lower operating temperature limit (-25°C versus -40°C). The Nichicon part provides extended reliability margins. Electrical performance at rated conditions is equivalent.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 227LMB250M2CC and LGR2E221MELA25 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements and supply chain strategy. Both parts are active in production. The LGR2E221MELA25 offers extended operational lifetime, making it suitable for applications requiring maximum reliability or extended service intervals.

Q: Are there any thermal or electrical performance differences that affect circuit operation?

A: Both parts operate within identical voltage and capacitance specifications. The substitute part demonstrates equal or superior ripple current handling at low frequency (1 A at 120 Hz versus 910 mA). No circuit performance degradation occurs with substitution.

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

A: The 227LMB250M2CC has MSL 1 (Unlimited). The LGR2E221MELA25 is not applicable for MSL classification. Both parts are suitable for standard handling and storage without special moisture control requirements.
