ESMG250ETC331MHB5D Equivalent & Substitute Parts

Part Overview

The ESMG250ETC331MHB5D is a 330 µF, 25 V aluminum electrolytic capacitor manufactured by Chemi-Con in the SMG series. This radial, through-hole component is rated for 2000 hours at 85°C and is designed for general-purpose applications requiring stable capacitance and ripple current handling. The part is currently in active production status with ROHS3 compliance and REACH unaffected certification.

Substitute parts become necessary when the primary manufacturer part experiences supply constraints, extended lead times, or inventory depletion. Equivalent components meeting identical electrical and mechanical specifications ensure design continuity and system reliability without circuit redesign.

Substitute Part Grouping Explanation

Substitution eligibility for the ESMG250ETC331MHB5D is determined by strict equivalence across the following parameters:

Mandatory Matching Parameters:

• Capacitance: 330 µF
• Tolerance: ±20%
• Voltage Rating: 25 V
• Lifetime: 2000 Hrs @ 85°C
• Operating Temperature: -40°C ~ 85°C
• Lead Spacing: 0.138" (3.50mm)
• Size / Dimension: 0.315" Dia (8.00mm)
• Height - Seated (Max): 0.512" (13.00mm)
• Mounting Type: Through Hole
• Package / Case: Radial, Can
• Polarization: Polar

All identified substitute parts meet these electrical and mechanical specifications. Ripple current ratings and packaging format (Tape & Reel vs. Cut Tape) represent secondary considerations that do not affect functional interchangeability in the circuit application.

Engineering Selection Recommendations

Primary Substitute: 860010474012 (Würth Elektronik WCAP-ATG8 Series)

The Würth Elektronik 860010474012 is the preferred substitute for the ESMG250ETC331MHB5D. Both components are in active production status, ensuring long-term availability and supply chain stability. The Würth part maintains identical electrical specifications and mechanical dimensions. Ripple current performance at 120 Hz (451 mA) and 100 kHz (622.38 mA) remains within acceptable operational parameters for general-purpose applications. ROHS3 compliance and REACH unaffected status align with regulatory requirements. The Cut Tape packaging format accommodates both manual and automated assembly processes.

Secondary Substitute: UVK1E331MPD1TD (Nichicon UVK Series)

The Nichicon UVK1E331MPD1TD meets all mandatory electrical and mechanical specifications. However, this component carries a "Not For New Designs" product status designation. This classification indicates that Nichicon has discontinued active development and marketing of this series, though existing inventory remains available. Selection of this part is appropriate only for legacy system maintenance, repair, or replacement applications where design continuity with original components is required. New circuit designs should prioritize the Würth Elektronik substitute or the primary manufacturer part.

Frequently Asked Questions (FAQ)

Q: Can the 860010474012 be directly substituted for the ESMG250ETC331MHB5D without PCB modification?

A: Yes. Both components share identical lead spacing (0.138" / 3.50mm), can diameter (0.315" / 8.00mm), and seated height (0.512" / 13.00mm). Through-hole mounting footprints are mechanically compatible. No PCB redesign is required.

Q: What is the significance of the "Not For New Designs" status on the Nichicon UVK1E331MPD1TD?

A: This designation indicates the manufacturer has transitioned the product to end-of-life status and is not recommending it for new circuit development. The part remains functionally equivalent and suitable for replacement in existing systems. New designs should utilize the Chemi-Con ESMG250ETC331MHB5D or Würth Elektronik 860010474012.

Q: Are there differences in ripple current handling between the three parts?

A: Ripple current ratings vary slightly across manufacturers. The Chemi-Con ESMG250ETC331MHB5D specifies 440 mA @ 120 Hz and 660 mA @ 100 kHz. The Würth Elektronik 860010474012 provides 451 mA @ 120 Hz and 622.38 mA @ 100 kHz. The Nichicon UVK1E331MPD1TD delivers 390 mA @ 120 Hz and 585 mA @ 10 kHz. All values support general-purpose applications within the specified operating parameters.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance?

A: No. Packaging format is a logistics and assembly consideration only. Tape & Reel (TR) and Cut Tape (CT) formats contain identical components with identical electrical characteristics. Selection depends on production volume and assembly equipment compatibility.

Q: Are all three parts compliant with current regulatory standards?

A: Yes. All three components are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations applicable to electronic components.

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

A: Lead spacing is specified as 0.138" (3.50mm) for all three parts. This dimension is the center-to-center distance between the two radial leads. Standard through-hole PCB footprints for 330 µF radial capacitors accommodate this spacing without modification.
