B41550E4100Q000 Equivalent & Substitute Parts

Part Overview

The B41550E4100Q000 is a 100000 µF, 16 V aluminum electrolytic capacitor with radial, can-style screw terminals manufactured by EPCOS - TDK Electronics. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

The part is designed for general-purpose applications requiring high capacitance values in a chassis-mount configuration. Its 20000-hour lifetime rating at 105°C and 10 mOhm ESR at 100 Hz define its performance envelope for power supply filtering, energy storage, and ripple current applications.

Substitute Part Grouping Explanation

Substitution of the B41550E4100Q000 is determined by the following critical parameters:

Capacitance Value: Must be 100000 µF (exact match required)
Voltage Rating: Substitute must equal or exceed 16 V
Package Configuration: Radial, can-style screw terminals with matching lead spacing (28.50 mm)
Mounting Type: Chassis mount configuration
Polarization: Polar (aluminum electrolytic)
Compliance: RoHS3 compliance maintained

The MAL210126104E3 from Vishay Beyschlag/Draloric/BC Components satisfies these substitution criteria. While it features a higher voltage rating (25 V) and improved ESR characteristics (7 mOhm), these represent performance enhancements rather than deviations from the functional requirements.

Engineering Selection Recommendations

The MAL210126104E3 is a direct functional substitute for the B41550E4100Q000. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

The substitute part offers improved electrical performance through lower ESR and impedance values, which reduce heat generation and improve transient response in power supply applications. The higher voltage rating (25 V versus 16 V) provides additional design margin without affecting circuit compatibility in 16 V applications.

Physical dimensions show minor variations: the substitute has a slightly larger diameter (65.00 mm versus 64.30 mm) and greater height (110.70 mm versus 106.70 mm). These differences remain within typical mechanical tolerances for chassis-mount screw terminal capacitors and do not preclude direct substitution in standard mounting configurations.

The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete original component.

Frequently Asked Questions (FAQ)

Q: Can the MAL210126104E3 be used as a direct replacement for the B41550E4100Q000?

A: Yes. Both components share identical capacitance (100000 µF), matching lead spacing (28.50 mm), identical package configuration (radial, can-style screw terminals), and equivalent mounting type (chassis mount). The substitute's higher voltage rating (25 V) is compatible with 16 V circuit applications.

Q: What are the physical dimension differences between these parts?

A: The MAL210126104E3 has a case diameter of 65.00 mm (versus 64.30 mm) and height of 110.70 mm (versus 106.70 mm). These variations are typical for aluminum electrolytic capacitors from different manufacturers and generally do not affect mounting compatibility in standard chassis configurations.

Q: How do the electrical performance characteristics compare?

A: The substitute part demonstrates superior electrical performance with lower ESR (7 mOhm versus 10 mOhm) and impedance (6 mOhms versus 9 mOhms). Ripple current capacity is marginally higher (19.6 A versus 19 A). These improvements reduce power dissipation and enhance circuit stability.

Q: Are there temperature rating differences to consider?

A: The original part is rated for -55°C to 105°C operation with 20000-hour lifetime at 105°C. The substitute operates from -40°C to 85°C with 15000-hour lifetime at 85°C. Applications requiring operation below -40°C or sustained exposure above 85°C should retain the original component specification.

Q: Do both parts meet current compliance standards?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement and use.

Q: What is the significance of the product status difference?

A: The original B41550E4100Q000 is obsolete, indicating discontinued manufacturing and limited availability. The MAL210126104E3 is in active production, ensuring reliable long-term supply and consistent quality control.
