Key Parameters

Substitute Part Grouping Explanation

Substitution for the UHD1E331MPD1TA is determined by strict equivalence in the following parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Radial, Can (exact match required)
• Lead Spacing: 0.138" (4.60mm) (exact match required)
• Physical Dimensions: 0.315" Dia × 0.650" Height (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lifetime: 3000 Hrs @ 105°C (exact match required)

Substitute parts are grouped into two categories:

Parametric Equivalents (Same Series): Parts within the Nichicon UHD series that share identical electrical and mechanical specifications.

Cross-Manufacturer Upgrades: Parts from Chemi-Con (KZE and LXZ series) that meet all electrical and mechanical parameters while offering enhanced product status or compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Performance): UHD1E331MPD1TD is a parametric equivalent within the Nichicon UHD series, offering identical electrical specifications and mechanical dimensions. Both parts share the same product status classification.

For Extended Temperature Range: UPW1E331MPD6TA extends the operating temperature range to -55°C ~ 105°C while maintaining all other electrical and mechanical parameters. This part is suitable for applications requiring wider temperature operation.

For Active Product Status: EKZE250ETD331MH15D (Chemi-Con KZE series) and ELXZ250ETC331MH15D / ELXZ250EC3331MH15D (Chemi-Con LXZ series) are classified as Active products. The Chemi-Con LXZ series parts carry AEC-Q200 automotive qualification and are suitable for automotive applications requiring active product support.

Packaging Considerations: Cut Tape (CT) packaging is available from Nichicon (UHD and UPW series). Tape & Reel (TR) packaging is available from Chemi-Con LXZ series for high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Can UHD1E331MPD1TD be used as a direct replacement for UHD1E331MPD1TA? A: Yes. Both parts are Nichicon UHD series capacitors with identical capacitance (330 µF), voltage rating (25 V), tolerance (±20%), lifetime (3000 Hrs @ 105°C), impedance (56 mOhms), and physical dimensions. The only difference is the packaging variant designation.

Q: What is the difference between UPW1E331MPD6TA and UHD1E331MPD1TA? A: The UPW series extends the operating temperature range to -55°C ~ 105°C compared to the UHD series range of -40°C ~ 105°C. The UPW part has a higher impedance (85 mOhms vs. 56 mOhms) and lower ripple current rating at 120 Hz (474.5 mA vs. 532 mA). All other parameters remain equivalent.

Q: Are Chemi-Con LXZ series parts (ELXZ250ETC331MH15D, ELXZ250EC3331MH15D) suitable for automotive applications? A: Yes. Both Chemi-Con LXZ series parts carry AEC-Q200 automotive qualification and are classified as Active products. They maintain the required 330 µF capacitance, 25 V voltage rating, and 3000 Hrs @ 105°C lifetime. The extended temperature range (-55°C ~ 105°C) is suitable for automotive environments.

Q: What is the difference between EKZE250ETD331MH15D and the LXZ series parts? A: EKZE250ETD331MH15D (Chemi-Con KZE series) is an Active product with identical electrical specifications to the original UHD1E331MPD1TA, including the same operating temperature range (-40°C ~ 105°C) and impedance (56 mOhms). The LXZ series parts offer extended temperature range (-55°C ~ 105°C) and automotive qualification (AEC-Q200), but with higher impedance (90 mOhms).

Q: Does packaging type affect electrical performance? A: No. Cut Tape (CT) and Tape & Reel (TR) packaging are logistics variants only. Both packaging types contain identical electrical components. Selection depends on production volume and assembly equipment compatibility.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts are RoHS3 compliant and meet the same environmental compliance standards as the original UHD1E331MPD1TA.
