EKMM401VSN101MP30S Equivalent & Substitute Parts

Part Overview

The EKMM401VSN101MP30S is a 100 µF, 400 V aluminum electrolytic capacitor manufactured by Chemi-Con in the KMM series. This radial, can-style snap-in component is rated for 3000 hours at 105°C and is designed for general-purpose applications requiring high-voltage energy storage and filtering. The part is currently in active production status with 1108 units available in inventory.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design flexibility permits selection from qualified alternatives that meet identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the EKMM401VSN101MP30S is determined by strict equivalence across the following critical parameters:

Capacitance value: 100 µF (exact match required)
Voltage rating: 400 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime rating: 3000 Hrs @ 105°C (exact match required)
Operating temperature range: -25°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)
Package configuration: Radial, Can - Snap-In (exact match required)
Lead spacing: 0.394" (10.00 mm) (exact match required)
Physical dimensions: 0.866" Dia × 1.260" Height (exact match required)
Mounting type: Through Hole (exact match required)

The substitute part 400MXC100MEFCSN22X30 (Rubycon MXC series) meets all specified electrical and mechanical parameters and is therefore classified as a parametric equivalent.

Engineering Selection Recommendations

The EKMM401VSN101MP30S (Chemi-Con KMM series) is the primary selection for new designs due to its active product status. This part maintains full manufacturer support and is recommended for applications requiring long-term supply continuity.

The 400MXC100MEFCSN22X30 (Rubycon MXC series) is classified as "Not For New Designs" and should be used only when the primary part is unavailable or when existing designs require component replacement. This substitute meets all electrical and mechanical specifications and is suitable for legacy system maintenance and repair applications.

Both parts are RoHS3 compliant and carry identical electrical performance characteristics within the specified parameter set.

Frequently Asked Questions (FAQ)

Q: Can the 400MXC100MEFCSN22X30 be used as a direct replacement for the EKMM401VSN101MP30S?

A: Yes. Both parts are parametric equivalents with identical capacitance (100 µF), voltage rating (400 V), tolerance (±20%), lifetime rating (3000 Hrs @ 105°C), operating temperature range (-25°C ~ 105°C), and physical dimensions (0.866" Dia × 1.260" Height). The snap-in radial package and 10.00 mm lead spacing are identical, permitting direct PCB mounting without modification.

Q: Why is the Rubycon part marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and support for the MXC series. While the part remains functionally equivalent and available in inventory, new designs should specify the active EKMM401VSN101MP30S to ensure long-term supply availability and manufacturer technical support.

Q: Are there differences in ripple current performance between these parts?

A: The EKMM401VSN101MP30S specifies 1.001 A @ 50 kHz, while the 400MXC100MEFCSN22X30 specifies 980 mA @ 10 kHz. Both parts meet the 700 mA @ 120 Hz specification. The frequency and magnitude differences reflect manufacturer test conditions and do not affect substitution eligibility for applications within the specified parameter envelope.

Q: What is the lead spacing and how does it affect PCB compatibility?

A: Both parts feature 0.394" (10.00 mm) lead spacing, which is the standard pitch for this capacitor class. PCB footprints designed for either part are directly compatible with the other.

Q: Are both parts RoHS compliant?

A: Yes. The 400MXC100MEFCSN22X30 is explicitly RoHS3 compliant. Both parts carry the same HTSUS classification (8532.22.0040) and ECCN designation (EAR99).
