Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP272M100H7P3 is determined by strict alignment of the following critical parameters:

Electrical Parameters:

• Capacitance value: 2700 µF (exact match required)
• Voltage rating: 100 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)

Mechanical Parameters:

• Package type: Radial, Can - Snap-In (exact match required)
• Lead spacing: 0.394" (10.00 mm) (exact match required)
• Diameter: 1.378" (35.00 mm) (exact match required)
• Mounting type: Through Hole (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)

Substitute parts must satisfy all electrical, mechanical, and compliance criteria to ensure direct interchangeability without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

The LGU2A272MELC manufactured by Nichicon qualifies as a direct substitute for the LP272M100H7P3 based on alignment of all critical electrical, mechanical, and compliance parameters.

Electrical Compatibility: Both parts share identical capacitance (2700 µF), voltage rating (100 V), tolerance (±20%), and polarization (Polar). Operating temperature ranges are identical (-40°C ~ 105°C).

Mechanical Compatibility: Lead spacing (0.394" / 10.00 mm), diameter (1.378" / 35.00 mm), and mounting type (Through Hole, Radial Can Snap-In) are identical. The LGU2A272MELC exhibits a reduced seated height of 1.457" (37.00 mm) compared to 1.575" (40.00 mm) for the LP272M100H7P3, which provides additional clearance in space-constrained applications.

Performance Characteristics: The LGU2A272MELC demonstrates superior ripple current handling (2.9 A @ 120 Hz versus 2.32 A) and extended thermal lifetime (3000 Hrs @ 105°C versus 1000 Hrs), indicating enhanced reliability margins in high-temperature and high-ripple-current environments.

Compliance Status: Both parts maintain ROHS3 compliance, REACH Unaffected status, and identical ECCN (EAR99) and HTSUS (8532.22.0040) classifications, ensuring regulatory equivalence for procurement and supply chain purposes.

Product Status: Both components carry Active product status, confirming ongoing manufacturer support and availability.

Frequently Asked Questions (FAQ)

Q: Can the LGU2A272MELC replace the LP272M100H7P3 in existing circuit designs without modification?

A: Yes. Both parts meet identical electrical specifications (2700 µF, 100 V, ±20% tolerance) and mechanical requirements (lead spacing, diameter, snap-in package). The reduced height of the LGU2A272MELC (37.00 mm versus 40.00 mm) provides additional board clearance and does not create compatibility issues.

Q: What is the significance of the different lifetime ratings (1000 Hrs versus 3000 Hrs @ 105°C)?

A: The LGU2A272MELC provides a 3× longer thermal lifetime at 105°C, indicating superior capacitor construction and electrolyte formulation. This extended rating does not affect substitution eligibility but represents an enhanced reliability margin in applications subject to sustained elevated temperatures.

Q: Are the ripple current specifications interchangeable?

A: The LGU2A272MELC supports higher ripple current capacity (2.9 A @ 120 Hz) compared to the LP272M100H7P3 (2.32 A @ 120 Hz). This superior performance ensures the substitute part can handle equivalent or greater ripple current demands without thermal stress, making it suitable for direct replacement in all applications where the original part was specified.

Q: Do both parts require identical PCB footprints?

A: Yes. Lead spacing (0.394" / 10.00 mm) and diameter (1.378" / 35.00 mm) are identical, ensuring both parts use the same PCB footprint and snap-in mounting holes. No board redesign is required.

Q: Are there any regulatory or compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH Unaffected, and share identical ECCN (EAR99) and HTSUS (8532.22.0040) classifications. Procurement, supply chain, and regulatory documentation remain equivalent.

Q: What is the impact of the unspecified ESR value for the LGU2A272MELC?

A: The ESR specification for the LGU2A272MELC is not provided in the available technical data. The LP272M100H7P3 specifies 92 mOhm @ 120 Hz. For applications where ESR is a critical design parameter, direct measurement or manufacturer consultation of the LGU2A272MELC datasheet is required to confirm compatibility with specific circuit requirements.
