ESMH201VNN331MP30S Equivalent & Substitute Parts

Part Overview

The ESMH201VNN331MP30S is a 330 µF, 200 V aluminum electrolytic capacitor manufactured by Chemi-Con in the SMH 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 currently active in production.

Substitute parts are necessary when the original ESMH201VNN331MP30S becomes unavailable, when design requirements demand extended operational lifetime, or when higher voltage ratings are required for enhanced system reliability. Alternative manufacturers offer equivalent capacitance and voltage specifications with varying performance characteristics in ESR, ripple current handling, and thermal endurance.

Substitute Part Grouping Explanation

Substitution eligibility for the ESMH201VNN331MP30S is determined by the following critical parameters:

Primary Matching Criteria:

Capacitance: 330 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: 200 V minimum (equal or higher acceptable)
Package Type: Radial, Can - Snap-In (exact match required)
Lead Spacing: 10.00 mm (exact match required)
Case Diameter: 22.00 mm (exact match required)
Height: 32.00 mm maximum (exact match required)
Mounting Type: Through Hole (exact match required)
Polarization: Polar (exact match required)

Secondary Performance Parameters:

ESR (Equivalent Series Resistance): Lower values indicate improved performance
Lifetime at Temperature: Extended hours indicate superior thermal endurance
Operating Temperature Range: Wider ranges provide greater design flexibility
Ripple Current Capability: Higher values support increased current handling

Substitute parts are grouped into two categories: Direct Substitutes (200 V rated) and Upgrade Substitutes (250 V rated). Direct substitutes maintain the original 200 V specification. Upgrade substitutes provide higher voltage ratings, enabling operation in more demanding electrical environments while maintaining identical physical dimensions and capacitance values.

Engineering Selection Recommendations

Direct Substitutes (200 V Rated):

The LGR2D331MELZ30 (Nichicon LGR series) is the preferred direct substitute for the ESMH201VNN331MP30S. Both parts maintain the 200 V voltage specification and identical physical dimensions. The LGR2D331MELZ30 offers extended operational lifetime of 10,000 hours at 105°C compared to the original 2,000 hours at 85°C, providing superior thermal endurance. The part is currently active in production and ROHS3 compliant.

The B43504A2337M000 (EPCOS - TDK Electronics B43504 series) is a secondary direct substitute. It provides improved ESR performance (390 mOhm @ 100Hz versus 502 mOhm @ 120Hz) and extended lifetime (3,000 hours @ 105°C). However, this part carries a "Not For New Designs" status, limiting its suitability for new development projects.

Upgrade Substitutes (250 V Rated):

The 381LQ331M250H022 (Cornell Dubilier Electronics 381LQ series) is the recommended upgrade substitute. It maintains identical ESR (502 mOhm @ 120Hz) to the original part while providing a 50 V higher voltage rating (250 V). The part supports operation at 105°C maximum temperature and is currently active in production with ROHS3 compliance.

The 250MXG330MEFCSN22X30 (Rubycon MXG series) offers extended lifetime (3,000 hours @ 105°C) with 250 V voltage rating. This part is currently active and ROHS3 compliant, providing enhanced thermal performance for demanding applications.

The LGN2E331MELZ30 (Nichicon LGN series) provides 250 V rating with 3,000-hour lifetime at 105°C. This part is currently active in production and ROHS3 compliant.

The 380LQ331M250H022 (Cornell Dubilier Electronics 380LQ series) offers 250 V rating with higher ESR (603 mOhm @ 120Hz) and is suitable for applications where voltage margin is prioritized over ESR performance.

All substitute parts maintain identical physical dimensions (22.00 mm diameter, 32.00 mm height, 10.00 mm lead spacing), ensuring direct mechanical compatibility with the original ESMH201VNN331MP30S in through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can I use a 250 V rated capacitor in place of a 200 V rated capacitor?

A: Yes. A higher voltage rating provides additional electrical safety margin. The 250 V substitute parts (250MXG330MEFCSN22X30, 380LQ331M250H022, 381LQ331M250H022, LGN2E331MELZ30) are electrically and mechanically compatible with the 200 V ESMH201VNN331MP30S. The circuit will operate normally with no functional degradation.

Q: What is the difference between ESR values listed at different frequencies?

A: ESR (Equivalent Series Resistance) varies with frequency. The ESMH201VNN331MP30S specifies 502 mOhm @ 120Hz, while the B43504A2337M000 specifies 390 mOhm @ 100Hz. Lower ESR values indicate reduced heat generation and improved ripple current handling. ESR measurements at different frequencies are not directly comparable; consult manufacturer datasheets for frequency-specific performance curves.

Q: Why do some substitute parts have higher lifetime ratings?

A: Lifetime ratings (measured in hours at a specified temperature) reflect the capacitor's thermal endurance. The LGR2D331MELZ30 offers 10,000 hours at 105°C versus the original 2,000 hours at 85°C. Extended lifetime indicates superior internal construction and materials, providing longer operational reliability in high-temperature environments.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, meeting environmental and hazardous substance restrictions for electronic components.

Q: What is the significance of "Not For New Designs" status?

A: The B43504A2337M000 carries this designation, indicating that while the part remains available, the manufacturer does not recommend its use in new product development. Existing designs may continue using this part, but new applications should select from actively supported alternatives.

Q: Do all substitute parts have identical physical dimensions?

A: Yes. All substitute parts maintain the same case diameter (22.00 mm), height (32.00 mm maximum), and lead spacing (10.00 mm). They are mechanically interchangeable in through-hole PCB applications without requiring layout modifications.

Q: Which substitute offers the best overall performance?

A: The LGR2D331MELZ30 (Nichicon LGR series) provides the longest operational lifetime (10,000 hours @ 105°C) while maintaining the original 200 V voltage specification. For applications requiring higher voltage margin, the 381LQ331M250H022 (Cornell Dubilier 381LQ series) matches the original ESR while providing 250 V rating and extended temperature capability to 105°C.
