Key Parameters

Substitute Part Grouping Explanation

Substitution of the UHV1E331MPD1TA is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Rated voltage: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package type: Radial, Can through-hole configuration (exact match required)
• Physical dimensions: 0.315" diameter, 0.512" maximum height, 0.138" lead spacing (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Lifetime rating: 6000 Hrs @ 105°C (exact match required)

The EKZH250ETD331MHB5D from Chemi-Con meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Chemi-Con substitute carries an "Active" product status, ensuring continued availability and manufacturing support, whereas the original Nichicon part is designated "Not For New Designs."

Both parts are ROHS3 compliant and carry identical ECCN and HTSUS classifications. The substitute part is available in Tape & Box packaging, compared to the original Cut Tape packaging. Compliance certifications and regulatory classifications are equivalent between the two components.

Frequently Asked Questions (FAQ)

Q: Can the EKZH250ETD331MHB5D replace the UHV1E331MPD1TA in existing designs?

A: Yes. The substitute part meets all critical electrical and mechanical parameters. Capacitance, voltage rating, tolerance, operating temperature range, lifetime rating, physical dimensions, and lead spacing are identical. Both components are through-hole mounted with matching footprints.

Q: What is the difference in ripple current ratings between these parts?

A: The UHV1E331MPD1TA is rated for 495 mA at 120 Hz and 990 mA at 100 kHz. The EKZH250ETD331MHB5D is rated for 450 mA at 120 Hz and 900 mA at 100 kHz. Both ratings remain within acceptable operating parameters for general purpose applications. Circuit design should account for the lower ripple current specification of the substitute part.

Q: Are there packaging differences between these parts?

A: The original part is supplied in Cut Tape (CT) packaging. The substitute is supplied in Tape & Box (TB) packaging. Both packaging formats are suitable for through-hole assembly processes. Tape & Box packaging provides additional protection during storage and handling.

Q: What is the impedance difference, and does it affect circuit performance?

A: The UHV1E331MPD1TA has an impedance of 59 mOhms, while the EKZH250ETD331MHB5D has an impedance of 62 mOhms. This 3 mOhm difference is negligible for general purpose applications and does not affect functional compatibility.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both components are ROHS3 compliant. The original part is REACH Affected; the substitute is REACH Unaffected. Both carry identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications.
