107LBA400M2CC Equivalent & Substitute Parts

Part Overview

The 107LBA400M2CC is a 100 µF, 400 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the LBA series. This radial, can-style snap-in capacitor is designed for general-purpose applications with a rated lifetime of 2000 hours at 85°C. The part is ROHS3 compliant and currently active in production with 864 units in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across alternative manufacturers and series. Substitution becomes necessary due to supply constraints, design upgrades for extended lifetime, improved thermal performance, or reduced equivalent series resistance (ESR) characteristics.

Substitute Part Grouping Explanation

Substitute parts for the 107LBA400M2CC are classified into three categories based on substitution criteria:

Category 1: Direct Electrical & Mechanical Equivalents (400V Rating) Parts maintaining 100 µF capacitance, 400 V voltage rating, ±20% tolerance, identical mechanical dimensions (25.00 mm diameter, 27.00 mm height, 10.00 mm lead spacing), through-hole radial snap-in package, and ROHS3 compliance. These parts differ in ESR characteristics, lifetime ratings, and operating temperature ranges but maintain full pin-for-pin and form-factor compatibility.

Category 2: Upgraded Performance Variants (400V Rating) Parts with identical electrical ratings (100 µF, 400 V, ±20%) and mechanical form factors but offering extended lifetime (3000 hours or greater at elevated temperatures), improved ESR performance, or extended operating temperature ranges (-40°C upper limit). These represent direct upgrades suitable for applications requiring enhanced reliability.

Category 3: Higher Voltage Alternatives (450V Rating) Parts rated at 450 V with 100 µF capacitance and ±20% tolerance. These provide voltage margin above the 400 V requirement while maintaining identical mechanical dimensions and snap-in package configuration. Suitable for applications where voltage derating is beneficial.

Engineering Selection Recommendations

For Direct Replacement (Same Electrical & Thermal Profile): The ELH107M400AR1AA (KEMET) maintains identical voltage rating (400 V), capacitance (100 µF), tolerance (±20%), lifetime (2000 Hrs @ 85°C), and operating temperature range (-25°C to 85°C) as the 107LBA400M2CC. This part is ROHS3 compliant and Active in production status, making it suitable for direct substitution in existing designs without thermal or electrical re-qualification.

For Extended Lifetime Applications (400V): The 107LBB400M2CC (Cornell Dubilier LBB series) provides a 50% increase in lifetime (3000 Hrs @ 85°C) while maintaining the same voltage rating and capacitance. Extended operating temperature range (-40°C to 85°C) provides additional thermal margin. This upgrade is recommended for applications requiring enhanced reliability without design modification.

The B43624B9107M000 (EPCOS - TDK) offers the longest lifetime at 400 V rating (8000 Hrs @ 85°C) with significantly reduced ESR (0.780 Ω @ 100Hz). This part is Active in production and ROHS3 compliant, suitable for high-reliability applications.

For Enhanced Thermal Performance (400V): The 380LX101M400J012 (Cornell Dubilier 380LX series) delivers improved ESR performance (1.65 Ω @ 120Hz) with 3000-hour lifetime at 85°C. The B43509B9107M000 (EPCOS - TDK B43509 series) provides superior ESR (0.800 Ω @ 100Hz) with extended temperature capability (-40°C to 105°C) and 3000-hour lifetime at 105°C. Both are Active in production and ROHS3 compliant.

For Voltage Margin Applications (450V): The B43644B5107M000 (EPCOS - TDK B43644 series) provides 450 V rating with 5000-hour lifetime at 105°C and extended temperature range (-40°C to 105°C). The LGN2W101MELA25 (Nichicon LGN series) offers 450 V rating with 3000-hour lifetime at 105°C and -25°C to 105°C operating range. Both maintain identical mechanical form factors and are ROHS3 compliant and Active in production.

Avoid for New Designs: The B43504B9107M000 (EPCOS - TDK B43504 series) is marked "Not For New Designs" and should not be selected for new applications despite offering superior ESR performance.

Frequently Asked Questions (FAQ)

Q: Can the 107LBA400M2CC be replaced with a 450 V rated capacitor? A: Yes. Parts rated at 450 V (B43644B5107M000, LGN2W101MELA25, LKX2W101MESA25) maintain identical mechanical dimensions, lead spacing, and snap-in package configuration. The higher voltage rating provides additional safety margin in 400 V applications. All substitute 450 V parts are ROHS3 compliant and maintain the same 100 µF capacitance and ±20% tolerance.

Q: What is the significance of ESR differences between substitute parts? A: Equivalent Series Resistance (ESR) affects ripple current handling and heat dissipation. Lower ESR values (0.582 Ω to 0.980 Ω) indicate improved high-frequency performance and reduced thermal stress. The original 107LBA400M2CC has ESR of 2.4868 Ω @ 120Hz. Substitute parts with lower ESR (ELH107M400AR1AA at 0.582 Ω, B43509B9107M000 at 0.800 Ω) provide enhanced performance in ripple-current-intensive applications.

Q: Are all substitute parts mechanically compatible with the original 107LBA400M2CC? A: Yes. All listed substitute parts maintain identical mechanical specifications: 25.00 mm case diameter, 27.00 mm maximum seated height, 10.00 mm lead spacing, and radial snap-in package configuration. Through-hole mounting compatibility is preserved across all substitutes.

Q: Which substitute offers the longest operational lifetime? A: The B43624B9107M000 (EPCOS - TDK B43624 series) provides 8000 hours at 85°C, representing a 4x increase over the original 107LBA400M2CC (2000 hours at 85°C). For applications requiring operation at 105°C, the B43644B5107M000 offers 5000 hours at 105°C.

Q: What is the difference between the 107LBB400M2CC and 107LBA400M2CC? A: The 107LBB400M2CC is an upgraded variant from the same manufacturer (Cornell Dubilier) with identical electrical ratings but extended lifetime (3000 Hrs @ 85°C vs. 2000 Hrs @ 85°C) and expanded operating temperature range (-40°C to 85°C vs. -25°C to 85°C). ESR remains identical at 2.4868 Ω @ 120Hz.

Q: Can I use the B43504B9107M000 in new designs? A: No. The B43504B9107M000 is marked "Not For New Designs" by EPCOS - TDK Electronics. Use the B43509B9107M000 (Active status) instead, which offers superior ESR (0.800 Ω @ 100Hz) and identical lifetime/temperature specifications.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, maintaining environmental compliance equivalent to the original 107LBA400M2CC.

Q: Which substitute has the lowest ESR performance? A: The ELH107M400AR1AA (KEMET ELH series) provides the lowest ESR at 0.582 Ω @ 20kHz, followed by the B43509B9107M000 at 0.800 Ω @ 100Hz and B43624B9107M000 at 0.780 Ω @ 100Hz. Lower ESR improves ripple current handling and reduces thermal dissipation.
