LLS1H272MELZ Equivalent & Substitute Parts

Part Overview

The LLS1H272MELZ is a 2700 µF, 50 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 stable capacitance and reliable performance across industrial temperature ranges. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design requirements necessitate alternative thermal or performance characteristics within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLS1H272MELZ is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Capacitance value (2700 µF), tolerance (±20%), and rated voltage (50 V) must be identical
• Mechanical Compatibility: Package type (Radial, Can - Snap-In), lead spacing (10.00 mm), physical dimensions (22.00 mm diameter, 32.00 mm height maximum), and through-hole mounting must match exactly
• Polarization: Polar configuration must be maintained
• Compliance: RoHS3 compliance status must be equivalent or superior

The LGU1H272MELZ qualifies as a direct substitute based on these parameters. While the LGU series demonstrates enhanced thermal performance (3000 Hrs @ 105°C versus 3000 Hrs @ 85°C) and extended operating temperature range (-40°C ~ 105°C versus -40°C ~ 85°C), all mechanical and primary electrical specifications remain identical, enabling direct board-level substitution.

Parameter Comparison

Engineering Selection Recommendations

Both LLS1H272MELZ and LGU1H272MELZ are Active product status components manufactured by Nichicon and maintain ROHS3 compliance. Selection between these parts should be based on application thermal requirements:

• LLS1H272MELZ: Select for applications operating within -40°C to 85°C temperature range where standard thermal performance is sufficient
• LGU1H272MELZ: Select for applications requiring extended thermal performance, higher ambient temperatures up to 105°C, or designs prioritizing component longevity in elevated temperature environments

Both parts are electrically and mechanically interchangeable at the board level. No circuit modifications or PCB layout changes are required when substituting between these part numbers.

Frequently Asked Questions (FAQ)

Q: Can LGU1H272MELZ be used as a direct replacement for LLS1H272MELZ?

A: Yes. Both parts share identical capacitance (2700 µF), voltage rating (50 V), tolerance (±20%), package type (Radial, Can - Snap-In), and physical dimensions. No board modifications are required.

Q: What is the primary difference between these substitute parts?

A: The LGU series provides enhanced thermal performance with a maximum operating temperature of 105°C and 3000-hour lifetime rating at 105°C, compared to the LLS series rated to 85°C. The LGU series also exhibits lower ripple current specifications.

Q: Are there any mechanical compatibility concerns when substituting?

A: No. Both parts maintain identical lead spacing (10.00 mm), case diameter (22.00 mm), and maximum seated height (32.00 mm). Through-hole mounting compatibility is preserved.

Q: Do both parts meet the same compliance standards?

A: Yes. Both LLS1H272MELZ and LGU1H272MELZ are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements.

Q: Which part should be selected for high-temperature applications?

A: The LGU1H272MELZ is specified for applications requiring sustained operation at temperatures approaching 105°C. The LLS1H272MELZ is suitable for applications within the -40°C to 85°C range.
