Substitute Part Grouping Explanation

Substitution of the LP272M100H9P3 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Direct Substitution:

• Capacitance: 2700 µF (exact match required)
• Voltage Rating: 100 V (minimum; higher ratings acceptable for upgrade scenarios)
• Tolerance: ±20% (standard tolerance class)
• Polarization: Polar (electrolytic type)
• Package / Case: Radial, Can - Snap-In (mechanical compatibility)
• Mounting Type: Through Hole (PCB interface requirement)
• Lead Spacing: 0.394" (10.00 mm) (footprint compatibility)
• Size / Dimension: 1.378" Dia (35.00 mm) (board space constraint)
• Operating Temperature Range: -40°C to 105°C (functional envelope)

Substitution Categories:

1. Direct Equivalent (LGU2A272MELC): Identical electrical ratings (2700 µF, 100 V) with matching mechanical form factor. Mechanical height differs (37.00 mm vs. 50.00 mm), which may affect board layout but does not prevent substitution in standard applications.

2. Upgrade Substitute (LGU2C272MELC): Elevated voltage rating (160 V vs. 100 V) with identical capacitance and mechanical footprint. Extended lifetime rating (3000 Hrs @ 105°C vs. 1000 Hrs @ 105°C). Mechanical height matches the original part (50.00 mm). This part provides enhanced performance margin and extended operational life.

Parameter Comparison

Engineering Selection Recommendations

LGU2A272MELC (Direct Equivalent): This Nichicon part maintains electrical parity with the LP272M100H9P3 across all critical parameters: 2700 µF capacitance, 100 V voltage rating, ±20% tolerance, and identical mechanical footprint (lead spacing and diameter). The reduced height (37.00 mm vs. 50.00 mm) provides additional board layout flexibility without compromising electrical function. Both parts are ROHS3 compliant and REACH unaffected. The LGU2A272MELC offers extended lifetime (3000 Hrs @ 105°C vs. 1000 Hrs @ 105°C), resulting in improved reliability over the product lifecycle. This part is suitable for direct replacement in applications where the original LP272M100H9P3 is specified.

LGU2C272MELC (Upgrade Substitute): This Nichicon part provides enhanced performance through elevated voltage rating (160 V vs. 100 V) while maintaining identical capacitance (2700 µF) and mechanical compatibility. The mechanical height matches the original part exactly (50.00 mm), ensuring no board layout modifications are required. The LGU2C272MELC delivers the same extended lifetime as the LGU2A272MELC (3000 Hrs @ 105°C). The higher voltage rating provides increased safety margin in applications subject to voltage transients or design margin requirements. Both substitute parts are ROHS3 compliant, REACH unaffected, and classified under the same HTSUS code (8532.22.0040).

Frequently Asked Questions (FAQ)

Q: Can the LGU2A272MELC be used as a direct replacement for the LP272M100H9P3?

A: Yes. The LGU2A272MELC is electrically equivalent with matching capacitance (2700 µF), voltage rating (100 V), tolerance (±20%), and mechanical footprint (lead spacing 10.00 mm, diameter 35.00 mm). The reduced height (37.00 mm vs. 50.00 mm) does not prevent substitution and may provide board layout advantages. Both parts are through-hole mounted, ROHS3 compliant, and operate across the same temperature range (-40°C to 105°C).

Q: What is the primary advantage of the LGU2C272MELC over the LP272M100H9P3?

A: The LGU2C272MELC provides two key advantages: (1) elevated voltage rating of 160 V compared to 100 V, offering increased safety margin against voltage transients, and (2) extended lifetime of 3000 hours at 105°C compared to 1000 hours, improving long-term reliability. The mechanical height (50.00 mm) matches the original part, requiring no board layout modifications.

Q: Are there any mechanical compatibility issues when substituting these parts?

A: The LGU2A272MELC has a reduced height (37.00 mm vs. 50.00 mm) compared to the LP272M100H9P3. This does not affect electrical function or lead spacing (both 10.00 mm) but may require verification of available board clearance above the component. The LGU2C272MELC maintains identical height (50.00 mm) and requires no mechanical verification.

Q: Do all three parts meet the same regulatory and compliance standards?

A: Yes. The LP272M100H9P3, LGU2A272MELC, and LGU2C272MELC are all ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS code 8532.22.0040. All three parts are suitable for applications with equivalent regulatory requirements.

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

A: The LP272M100H9P3 specifies ripple current of 2.32 A at 120 Hz and 2.784 A at 100 kHz. The LGU2A272MELC provides higher ripple current capacity (2.9 A at 120 Hz and 3.335 A at 50 kHz). The LGU2C272MELC delivers the highest ripple current capacity (4 A at 120 Hz and 6 A at 50 kHz), reflecting its higher voltage rating and enhanced thermal performance.

Q: Can the LGU2C272MELC be used in applications originally designed for the LP272M100H9P3?

A: Yes. The LGU2C272MELC is mechanically and electrically compatible with the LP272M100H9P3. The elevated voltage rating (160 V vs. 100 V) does not create incompatibility; it provides additional performance margin. The identical mechanical height (50.00 mm) and lead spacing (10.00 mm) ensure direct board-level compatibility without layout modifications.

Q: What is the moisture sensitivity level (MSL) for these substitute parts?

A: The LGU2A272MELC and LGU2C272MELC are classified as "Not Applicable" for moisture sensitivity level, indicating these parts do not require moisture-controlled storage or handling procedures. The LP272M100H9P3 is classified as MSL 1 (Unlimited), also indicating no moisture sensitivity constraints.
