Substitute Part Grouping Explanation

Substitution eligibility for the UPW1V331MPD1TD is determined by strict matching of the following electrical and mechanical parameters:

Capacitance value: 330 µF (exact match required)
Voltage rating: 35 V (exact match required)
Tolerance: ±20% (exact match required)
Package configuration: Radial, Can (exact match required)
Mounting type: Through Hole (exact match required)
Lead spacing: 0.197" (5.00 mm) (exact match required)
Physical dimensions: 0.394" diameter × 0.689" height (exact match required)
Operating temperature range: -55°C to 105°C (exact match required)

All three substitute parts meet these core substitution criteria. Secondary parameters such as lifetime rating, ripple current specifications, impedance, and product status are provided for engineering evaluation but do not disqualify substitution based on the primary electrical and mechanical requirements.

Engineering Selection Recommendations

All three substitute parts are electrically and mechanically compatible with the UPW1V331MPD1TD based on core parameter matching. Selection among these alternatives should be based on the following considerations:

860160575024 (Würth Elektronik WCAP-ATLL): This part offers an extended lifetime rating of 6000 hours at 105°C compared to the original 5000 hours, providing improved reliability margin. Product status is Active, ensuring continued availability. RoHS3 compliance is maintained.

ELXZ350ETD331MJ16S (Chemi-Con LXZ): This part carries AEC-Q200 automotive qualification and is designated for automotive applications. It maintains the same impedance (68 mOhms) and lifetime rating (5000 Hrs @ 105°C) as the original part. Product status is Active with RoHS3 compliance.

860080575015 (Würth Elektronik WCAP-ATLI): This part offers the lowest impedance (38 mOhms) and highest ripple current capability (1.4 A @ 100 kHz) among the substitutes. Product status is Active with RoHS3 compliance. This option provides enhanced performance headroom for ripple current-sensitive applications.

All substitute parts maintain ROHS3 compliance and REACH Unaffected status consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can these substitute parts be used as direct replacements for the UPW1V331MPD1TD?

A: Yes. All three substitute parts match the core electrical parameters (330 µF, 35 V, ±20% tolerance) and mechanical specifications (radial can package, 5.00 mm lead spacing, 10.00 mm diameter, 17.50 mm height, through-hole mounting). They are electrically and mechanically interchangeable.

Q: What is the difference between the three substitute options?

A: The primary differences are lifetime rating, ripple current capability, impedance, and product applications. The Würth 860160575024 offers extended lifetime (6000 Hrs). The Chemi-Con ELXZ350ETD331MJ16S includes automotive qualification (AEC-Q200). The Würth 860080575015 provides the lowest impedance and highest ripple current rating.

Q: Are all substitutes RoHS compliant?

A: Yes. All three substitute parts are ROHS3 Compliant, matching the compliance status of the original UPW1V331MPD1TD.

Q: Why is the original part marked "Not For New Designs"?

A: This designation indicates that Nichicon has discontinued this part number from its active product line. Substitute parts with Active status are recommended for new applications, while the original part remains available for legacy system support and repair.

Q: Do the differences in impedance and ripple current affect substitution suitability?

A: Impedance and ripple current are secondary performance parameters. All substitutes meet the minimum electrical requirements for direct replacement. Applications with specific ripple current or impedance constraints should select the substitute that best matches those requirements.

Q: Are there any packaging or lead configuration differences?

A: No. All parts use identical radial can packaging with 5.00 mm lead spacing and matching physical dimensions, ensuring compatibility with existing PCB layouts and through-hole mounting.
