Equivalent & Substitute Parts for 107LBA400M2BD

Part Overview

The 107LBA400M2BD 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 rated for 2000 hours at 85°C and is designed for general-purpose applications requiring through-hole mounting. The part is currently active in production.

Substitute parts are necessary when the original part becomes unavailable, when design requirements demand extended operational lifetime, higher temperature ratings, or improved electrical characteristics such as lower equivalent series resistance (ESR) or higher ripple current handling capability.

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Performance):

The 107LBB400M2BD from Cornell Dubilier / Illinois Capacitor serves as the primary direct substitute. It maintains identical capacitance, voltage, tolerance, and ESR specifications while offering extended lifetime (3000 hours at 85°C versus 2000 hours) and expanded operating temperature range (-40°C to 85°C). This part is active in production and ROHS3 compliant.

For Applications Requiring Extended Lifetime:

The 400VXG100MEFCSN22X30 (Rubycon VXG series) is recommended for designs requiring extended operational life. This part delivers 5000 hours at 105°C while maintaining 400 V rating and identical mechanical dimensions. It is active in production and ROHS3 compliant.

The ELXM401VSN101MP30S (Chemi-Con LXM series) offers the highest lifetime rating at 7000 hours at 105°C with 400 V rating. This part is active in production and RoHS compliant.

For Applications Requiring Higher Voltage Rating:

The 381LX101M450H022 (Cornell Dubilier Electronics 381LX series) provides 450 V rating with 3000 hours at 105°C. This part is active in production and ROHS3 compliant.

Parts Not Recommended for New Designs:

The B43501A9107M000 (EPCOS - TDK Electronics B43501 series) and 400MXC100MEFCSN22X30 (Rubycon MXC series) are marked "Not For New Designs" and should be avoided in new product development despite their technical compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use a 450 V rated capacitor in place of the 107LBA400M2BD (400 V)?

A: Yes. A higher voltage rating is electrically compatible and provides additional safety margin. Parts such as 381LX101M450H022, B43508A5107M000, B43644A5107M000, and LGN2W101MELZ30 are all rated 450 V and are mechanically and electrically compatible substitutes.

Q: What is the significance of ESR (Equivalent Series Resistance) in selecting a substitute?

A: ESR affects ripple current handling, heat generation, and frequency response. Lower ESR values indicate better high-frequency performance. The original 107LBA400M2BD has ESR of 2.4868 Ω @ 120 Hz. Substitutes with lower ESR values (such as B43501A9107M000 at 660 mΩ or B43644A5107M000 at 970 mΩ) provide improved performance in applications with significant AC ripple current.

Q: Are all substitute parts mechanically identical to the 107LBA400M2BD?

A: Yes. All listed substitute parts maintain the same mechanical specifications: 0.866" diameter (22.00mm), 1.260" maximum height (32.00mm), 0.394" lead spacing (10.00mm), radial snap-in package, and through-hole mounting. They are direct mechanical replacements.

Q: What does "Not For New Designs" mean?

A: This designation indicates that the manufacturer has discontinued or is phasing out the part for new applications. While the part may still be available and functionally compatible, it should not be selected for new product designs. Use active-status alternatives instead.

Q: Can I use a capacitor with ±10% tolerance instead of ±20%?

A: Yes. A tighter tolerance (±10%) is more stringent than the original ±20% specification and is fully compatible. However, tighter tolerance parts may have different pricing and availability.

Q: What is the difference between lifetime ratings at 85°C versus 105°C?

A: Lifetime ratings specify the expected operational duration at a given temperature. A part rated 3000 hours at 105°C will have a longer actual lifetime at lower operating temperatures. If your application operates at 85°C or below, a part rated at 105°C will exceed the original 2000-hour specification at your actual operating temperature.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts are either ROHS3 compliant or RoHS compliant. The original 107LBA400M2BD is ROHS3 compliant. Compliance status is maintained across all recommended substitutes.

Q: Can I mix different substitute parts in the same circuit board?

A: Yes, provided all parts meet the circuit's electrical requirements (capacitance, voltage, tolerance, ripple current). However, for consistency and simplified inventory management, using a single substitute part number across a design is recommended.
