Key Parameters

Substitute Part Grouping Explanation

Substitution of aluminum electrolytic capacitors is determined by strict equivalence across the following parameters:

Primary Substitution Criteria:

• Capacitance value (100 µF)
• Voltage rating (450 V)
• Tolerance (±20%)
• Package configuration (Radial, Can - Snap-In)
• Mounting type (Through Hole)
• Physical dimensions (Lead spacing, case diameter, height)
• Polarization (Polar)

Secondary Compatibility Factors:

• Operating temperature range (minimum -25°C, maximum 105°C)
• RoHS3 compliance
• REACH compliance status

The substitute parts listed below meet all primary substitution criteria and maintain compatibility with the mechanical and electrical requirements of the 107LMB450M2CC. Differences in ESR (Equivalent Series Resistance), lifetime ratings, and ripple current specifications do not preclude substitution but represent performance variations within the general-purpose application category.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed—107LMB450M2CC, B43644B5107M000, and LGN2W101MELA25—are active production components with full RoHS3 and REACH compliance. Selection among these parts is based on availability and application-specific performance requirements.

107LMB450M2CC (Cornell Dubilier / Illinois Capacitor): Primary part with 998 units in stock. Suitable for standard general-purpose applications within the specified operating temperature range.

B43644B5107M000 (EPCOS - TDK Electronics): Upgrade substitute with extended lower operating temperature limit (-40°C versus -25°C). Offers improved ESR performance (980 mOhm @ 100 Hz) and extended lifetime rating (5000 hours @ 105°C versus 3000 hours). 906 units in stock. Recommended where enhanced thermal performance or extended service life is required.

LGN2W101MELA25 (Nichicon): Parametric equivalent with 2402 units in stock. Maintains identical electrical and mechanical specifications to the primary part. Highest inventory availability. Suitable for direct substitution in general-purpose applications.

All three parts are mechanically and electrically interchangeable within the specified parameters and may be selected based on procurement priority, inventory availability, and application performance requirements.

Frequently Asked Questions (FAQ)

Q: Can B43644B5107M000 be used as a direct replacement for 107LMB450M2CC?

A: Yes. Both parts share identical capacitance (100 µF), voltage rating (450 V), tolerance (±20%), package configuration (Radial, Can - Snap-In), and physical dimensions (lead spacing, case diameter, height). The B43644B5107M000 features an extended lower operating temperature limit (-40°C) and improved ESR characteristics, making it a compatible upgrade substitute.

Q: What is the difference between an upgrade substitute and a parametric equivalent?

A: An upgrade substitute (B43644B5107M000) meets all primary substitution criteria and offers enhanced performance characteristics such as lower ESR or extended lifetime ratings. A parametric equivalent (LGN2W101MELA25) meets all primary substitution criteria with performance characteristics equivalent to the original part. Both are fully interchangeable.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts share identical lead spacing (0.394" / 10.00 mm), case diameter (0.984" / 25.00 mm), and maximum seated height (1.063" / 27.00 mm). They are mechanically interchangeable in through-hole PCB applications.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected. They meet identical regulatory and environmental compliance requirements.

Q: What is the significance of the operating temperature range difference in B43644B5107M000?

A: The B43644B5107M000 operates from -40°C to 105°C, compared to -25°C to 105°C for the 107LMB450M2CC and LGN2W101MELA25. This extended lower temperature limit allows operation in colder environments. For applications operating within the -25°C to 105°C range, all three parts are equivalent.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All three parts have identical lead spacing (10.00 mm) and case diameter (25.00 mm), allowing direct substitution on PCBs designed for the 107LMB450M2CC without layout modifications.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements and inventory availability. For standard general-purpose applications, any of the three parts is suitable. The B43644B5107M000 is recommended where extended temperature range or improved ESR performance is beneficial. The LGN2W101MELA25 offers the highest inventory availability.
