Substitute Part Grouping Explanation

Substitution for the UPW1V101MPH is determined by strict equivalence across the following critical parameters: capacitance value (100 µF), voltage rating (minimum 35 V), tolerance (±20%), package type (radial, can), mounting type (through hole), physical dimensions (lead spacing, diameter, height), and operating temperature range (-55°C to 105°C). Parts are grouped into three categories based on their relationship to the main part:

Direct Equivalent (Same Voltage Rating): UPW1V101MPD maintains identical electrical specifications and physical form factor, differing only in packaging format and product status.

Upgrade Substitute (Higher Voltage Rating): UPW1H101MPD provides the same capacitance and physical dimensions but with a 50 V voltage rating, allowing operation in circuits requiring higher voltage margin while maintaining backward compatibility in 35 V applications.

Cross-Manufacturer Equivalent: EEU-FC1V101 from Panasonic matches the 100 µF, 35 V specification and physical package, with AEC-Q200 automotive qualification and active product status.

Engineering Selection Recommendations

UPW1V101MPD is the direct equivalent for applications requiring identical electrical and mechanical specifications. This part maintains the same 35 V voltage rating, 100 µF capacitance, and 3000-hour lifetime at 105°C. It is ROHS3 compliant and available in bulk packaging with higher inventory levels than the main part.

UPW1H101MPD serves as an upgrade substitute where circuit design permits higher voltage operation. The 50 V rating provides additional safety margin in 35 V applications while maintaining identical physical form factor and capacitance. The increased impedance (234 mOhms versus 117 mOhms) and reduced ripple current capacity at low frequency should be evaluated for ripple-sensitive applications.

EEU-FC1V101 from Panasonic is suitable for applications requiring active product status and automotive-grade qualification (AEC-Q200). This part matches the electrical and physical specifications of the main part with ROHS3 compliance. The reduced lifetime rating of 2000 hours at 105°C versus 3000 hours should be considered for long-life applications.

Frequently Asked Questions (FAQ)

Q: Can UPW1V101MPD be used as a direct replacement for UPW1V101MPH?

A: Yes. Both parts share identical capacitance (100 µF), voltage rating (35 V), tolerance (±20%), physical dimensions, lead spacing, and operating temperature range. The primary differences are packaging format and product status classification.

Q: Is UPW1H101MPD compatible with circuits designed for 35 V operation?

A: Yes. The 50 V rating of UPW1H101MPD exceeds the 35 V requirement, making it electrically compatible. However, the doubled impedance (234 mOhms versus 117 mOhms) and reduced ripple current at low frequency may affect performance in applications with strict ripple or transient response requirements.

Q: What is the advantage of selecting EEU-FC1V101 over Nichicon alternatives?

A: EEU-FC1V101 holds active product status and AEC-Q200 automotive qualification, ensuring continued availability and suitability for automotive applications. It maintains equivalent electrical specifications and physical form factor with ROHS3 compliance.

Q: Are all substitute parts through-hole mounted with identical lead spacing?

A: Yes. All listed substitutes maintain 0.138" (4.60 mm) lead spacing and through-hole mounting type, ensuring direct PCB compatibility without layout modifications.

Q: How does the lifetime rating difference affect part selection?

A: The main part and direct equivalent (UPW1V101MPD) provide 3000 hours at 105°C, while EEU-FC1V101 provides 2000 hours. For applications requiring extended operational life at elevated temperatures, the Nichicon parts are preferred.
