ESMG250ETD331MHB5D Equivalent & Substitute Parts

Part Overview

The ESMG250ETD331MHB5D 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 is unavailable, when alternative packaging formats are required, or when inventory constraints necessitate sourcing from alternative manufacturers while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ESMG250ETD331MHB5D are qualified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters:

Electrical Parameters (Must Match Exactly):

• Capacitance: 330 µF
• Rated Voltage: 25 V
• Tolerance: ±20%
• Lifetime: 2000 Hrs @ 85°C
• Operating Temperature Range: -40°C ~ 85°C
• Polarization: Polar

Mechanical Parameters (Must Match Exactly):

• Lead Spacing: 0.138" (3.50mm)
• Diameter: 0.315" (8.00mm)
• Height (Seated Max): 0.512" (13.00mm)
• Mounting Type: Through Hole
• Package Type: Radial, Can

Regulatory Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Substitute parts may differ in packaging format (Tape & Reel versus Cut Tape) and ripple current specifications at specific frequencies, provided all critical parameters remain equivalent. Manufacturer and series designation changes are acceptable when all parametric requirements are satisfied.

Engineering Selection Recommendations

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

The Würth Elektronik 860010474012 is the preferred substitute for the ESMG250ETD331MHB5D. This part maintains full parametric equivalence across all critical electrical and mechanical specifications. Both parts are in active production status with ROHS3 compliance and REACH unaffected certification. The Würth part demonstrates ripple current performance within acceptable operational parameters (451 mA @ 120 Hz and 622.38 mA @ 100 kHz) and is available in higher inventory quantities (3545 pcs). The packaging format difference (Cut Tape versus Tape & Reel) does not affect electrical or mechanical compatibility in through-hole applications.

Secondary Substitute: UVK1E331MPD1TD (Nichicon UVK Series)

The Nichicon UVK1E331MPD1TD meets all critical parametric requirements and maintains full electrical and mechanical compatibility. However, this part carries a "Not For New Designs" product status designation, indicating that Nichicon has discontinued active development for this series. While the part remains functionally equivalent and is currently in stock (4100 pcs), it should be selected only when the primary substitute is unavailable or when existing designs require continuity with previously qualified components. Ripple current specifications differ at high frequency (585 mA @ 10 kHz versus 660 mA @ 100 kHz for the main part), but this variation remains within acceptable operational ranges for general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the 860010474012 be used as a direct replacement for ESMG250ETD331MHB5D in existing PCB designs?

A: Yes. The 860010474012 maintains identical lead spacing (0.138" / 3.50mm), diameter (0.315" / 8.00mm), and height (0.512" / 13.00mm) specifications. Both parts are through-hole radial can capacitors with identical electrical ratings (330 µF, 25 V, ±20%, 2000 Hrs @ 85°C). No PCB layout modifications are required.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for automated assembly processes. Cut Tape (CT) packaging supplies components on tape segments cut to specified lengths, suitable for manual assembly or smaller production runs. Both packaging formats contain identical components with identical electrical and mechanical specifications. The packaging format does not affect component performance or compatibility.

Q: Why is the Nichicon UVK1E331MPD1TD marked "Not For New Designs"?

A: This designation indicates that Nichicon has transitioned this series to end-of-life status and is no longer actively developing or promoting new applications using this part. However, the component remains functionally equivalent and is suitable for replacement in existing designs or when inventory availability of active-status alternatives is constrained. New product designs should prioritize the Würth Elektronik 860010474012 or the original Chemi-Con ESMG250ETD331MHB5D.

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

A: Ripple current specifications vary slightly between manufacturers. The ESMG250ETD331MHB5D handles 440 mA @ 120 Hz and 660 mA @ 100 kHz. The 860010474012 handles 451 mA @ 120 Hz and 622.38 mA @ 100 kHz. The UVK1E331MPD1TD handles 390 mA @ 120 Hz and 585 mA @ 10 kHz. All three parts are rated for 2000 hours at 85°C and are suitable for general-purpose applications. Ripple current differences reflect manufacturing variations and do not affect substitutability for applications within the specified operating parameters.

Q: Do all three parts meet the same regulatory compliance standards?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected. They carry identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications. Regulatory compliance is equivalent across all substitute options.

Q: What is the operating temperature range for these capacitors?

A: All three parts operate across the identical temperature range of -40°C to 85°C. The 2000-hour lifetime specification applies at the maximum operating temperature of 85°C.
