LLG2C272MELC40 Equivalent & Substitute Parts

Part Overview

The LLG2C272MELC40 is a 2700 µF, 160 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Nichicon. This component is classified as Active product status and is designed for general purpose applications requiring high capacitance values at elevated voltage ratings. The LLG series operates across a temperature range of -40°C to 85°C with a rated lifetime of 2000 hours at 85°C. Equivalent and substitute parts are identified to provide design flexibility, inventory alternatives, and continuity of supply for applications where the primary part number may be unavailable or where upgraded performance characteristics are acceptable.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LLG2C272MELC40 are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance: 2700 µF (exact match required)
• Voltage Rating: 160 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)

Mechanical Compatibility Criteria:

• Package Type: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Size / Dimension: 1.378" Dia (35.00 mm) (exact match required)
• Height - Seated (Max): 1.654" (42.00 mm) (exact match required)
• Mounting Type: Through Hole (exact match required)

Compliance Criteria:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• REACH Status: REACH Unaffected (minimum requirement)

Substitute parts meeting all electrical and mechanical criteria are classified as direct equivalents. Variations in thermal performance (operating temperature range, lifetime at temperature) and ripple current ratings do not disqualify a part from substitution, provided all primary electrical and mechanical parameters match exactly.

Engineering Selection Recommendations

All three parts listed—LLG2C272MELC40, LGG2C272MELC40, and 380LQ272M160A042—meet the core electrical and mechanical substitution criteria. Selection among these parts is based on the following factors:

LGG2C272MELC40 (Nichicon Upgrade): This part represents an upgraded variant within the Nichicon product family. It maintains identical electrical and mechanical specifications while extending the maximum operating temperature to 105°C and providing a rated lifetime of 2000 hours at 105°C. This part is suitable for applications requiring enhanced thermal performance. Both parts carry Active product status and ROHS3 compliance.

380LQ272M160A042 (Cornell Dubilier Electronics Parametric Equivalent): This part is manufactured by Cornell Dubilier Electronics and provides parametric equivalence with specified ESR of 80 mOhm @ 120 Hz. It maintains identical capacitance, voltage, tolerance, package, and mechanical dimensions. This part is suitable for applications where multi-source qualification is required or where CDE component availability is preferred. All compliance certifications match the primary part.

All three parts are Active status products with ROHS3 compliance and REACH Unaffected status, ensuring regulatory compliance for current manufacturing and deployment.

Frequently Asked Questions (FAQ)

Q: Can LGG2C272MELC40 be used as a direct replacement for LLG2C272MELC40?

A: Yes. Both parts share identical capacitance (2700 µF), voltage rating (160 V), tolerance (±20%), package type (Radial, Can - Snap-In), lead spacing (10.00 mm), physical dimensions (1.378" Dia × 1.654" Height), and mounting type (Through Hole). The LGG variant offers extended operating temperature range (-40°C to 105°C versus -40°C to 85°C) and thermal lifetime rating (2000 Hrs @ 105°C versus 2000 Hrs @ 85°C), making it suitable for higher-temperature applications.

Q: Can 380LQ272M160A042 be used as a direct replacement for LLG2C272MELC40?

A: Yes. The 380LQ272M160A042 meets all electrical and mechanical substitution criteria: 2700 µF capacitance, 160 V voltage rating, ±20% tolerance, identical package type, lead spacing, and physical dimensions. The primary difference is manufacturer (Cornell Dubilier Electronics versus Nichicon) and specified ESR (80 mOhm @ 120 Hz). Both parts are Active status with ROHS3 compliance.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by exact matching of: capacitance value (2700 µF), voltage rating (160 V), tolerance (±20%), package type (Radial, Can - Snap-In), lead spacing (10.00 mm), physical dimensions (1.378" Dia, 1.654" Height maximum), mounting type (Through Hole), and polarization (Polar). Variations in thermal performance, ripple current ratings, and ESR do not disqualify substitution if all primary parameters match.

Q: Are there any compliance or certification differences among these parts?

A: No. All three parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected status, and Active product status. All parts are suitable for current manufacturing and deployment without additional qualification.

Q: What is the difference in ripple current ratings between these parts?

A: Ripple current ratings vary among the three parts. LLG2C272MELC40 and 380LQ272M160A042 both specify 5.45 A @ 120 Hz (low frequency) and higher ripple current at high frequency. LGG2C272MELC40 specifies lower ripple current ratings (3 A @ 120 Hz, 4.5 A @ 50 kHz). These differences reflect design variations between manufacturers and series but do not affect substitutability for applications within the specified electrical and mechanical parameters.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the design does not impose constraints beyond the specified electrical and mechanical parameters. All three parts are mechanically identical (same footprint, lead spacing, and mounting type) and electrically equivalent (same capacitance, voltage, and tolerance). Designs that depend on specific ripple current handling or thermal performance characteristics should be reviewed to confirm compatibility with the selected substitute.
