ESMM201VSN221MP20S Equivalent & Substitute Parts

Part Overview

The ESMM201VSN221MP20S is a 220 µF, 200 V aluminum electrolytic capacitor manufactured by Chemi-Con in the SMM series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring through-hole mounting. The component is currently active in production with RoHS compliance and unlimited moisture sensitivity rating. Substitute parts are identified when original inventory is unavailable or when application requirements necessitate alternative performance characteristics within compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESMM201VSN221MP20S is determined by strict equivalence in the following parameters:

Critical Matching Parameters:

• Capacitance: 220 µF (exact match required)
• Voltage Rating: 200 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 10.00 mm (exact match required)
• Physical Dimensions: 22.00 mm diameter, 22.00 mm height (exact match required)
• Mounting Type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

The substitute part LGJ2D221MELZ20 meets all critical matching parameters. Variations in operating temperature range, lifetime rating at different temperatures, ESR specifications, and ripple current ratings do not disqualify substitution when the above parameters are identical. These secondary parameters reflect different design approaches by manufacturers but do not affect mechanical or electrical compatibility in general-purpose applications.

Engineering Selection Recommendations

Primary Selection: ESMM201VSN221MP20S (Chemi-Con SMM Series)

The ESMM201VSN221MP20S is the specified component and should be used when available. It carries RoHS compliance and is actively produced. Current inventory status shows 950 pieces in stock.

Substitute Selection: LGJ2D221MELZ20 (Nichicon LGJ Series)

The LGJ2D221MELZ20 is a direct substitute based on matching all critical electrical and mechanical parameters. Both components are RoHS compliant and carry identical REACH and ECCN classifications. The substitute offers an extended operating temperature range (-40°C to 105°C versus -25°C to 85°C) and higher temperature lifetime rating (3000 hours at 105°C versus 3000 hours at 85°C). Current inventory shows 1023 pieces available.

Selection between these two parts should be based on:

• Availability and lead time requirements
• Application operating temperature environment
• Ripple current specifications for the specific circuit design
• Supplier preference and cost considerations

Both components are suitable for general-purpose applications with identical footprint and electrical ratings.

Frequently Asked Questions (FAQ)

Q: Can LGJ2D221MELZ20 be used as a direct replacement for ESMM201VSN221MP20S on the PCB?

A: Yes. Both components have identical lead spacing (10.00 mm), physical dimensions (22.00 mm diameter and height), and mounting type (through-hole, snap-in). No PCB layout modifications are required.

Q: What are the differences between these two capacitors?

A: The primary differences are manufacturer (Chemi-Con versus Nichicon) and series designation (SMM versus LGJ). The substitute offers a wider operating temperature range and higher temperature lifetime rating. Ripple current specifications differ between the two designs. All critical electrical parameters (capacitance, voltage, tolerance) and mechanical parameters (package, lead spacing, dimensions) are identical.

Q: Are both parts RoHS compliant?

A: Yes. ESMM201VSN221MP20S carries RoHS compliance certification. LGJ2D221MELZ20 carries ROHS3 compliance certification. Both meet regulatory requirements.

Q: Which part should I choose for high-temperature applications?

A: The LGJ2D221MELZ20 is rated for operation up to 105°C, compared to 85°C for the ESMM201VSN221MP20S. If your application requires sustained operation above 85°C, the Nichicon part is the appropriate selection.

Q: Do these capacitors have the same ripple current rating?

A: No. The ESMM201VSN221MP20S has higher ripple current ratings: 1.18 A at 120 Hz and 1.77 A at 100 kHz. The LGJ2D221MELZ20 has lower ripple current ratings: 760 mA at 120 Hz and 1.14 A at 50 kHz. Circuit design requiring specific ripple current handling should reference the appropriate datasheet.

Q: Are both parts available in the same packaging?

A: Yes. Both components are supplied in bulk packaging as radial, can-style snap-in capacitors suitable for through-hole assembly.

Q: What is the moisture sensitivity level for these parts?

A: ESMM201VSN221MP20S has MSL rating of 1 (Unlimited). LGJ2D221MELZ20 has MSL listed as Not Applicable. Both are suitable for standard storage and handling conditions.
