Nichicon UPW2F101MHD Equivalent & Substitute Parts

Part Overview

The Nichicon UPW2F101MHD is a 100 µF, 315 V aluminum electrolytic capacitor in radial, can package configuration designed for general purpose applications. This part operates across a temperature range of -40°C to 105°C with a rated lifetime of 8000 hours at 105°C. The UPW2F101MHD carries an obsolete product status, making identification of functionally equivalent alternatives necessary for ongoing system support and new design considerations.

Substitute Part Grouping Explanation

Substitution eligibility for the UPW2F101MHD is determined by the following core parameters: capacitance value (100 µF), tolerance (±20%), voltage rating (minimum 315 V), polarization (polar), mounting type (through hole), and package configuration (radial, can). Physical dimensions including lead spacing (7.50 mm), case diameter (18.00 mm), and height must remain compatible with the original PCB layout.

Two substitute parts meet these criteria:

UCS2V101MHD (Manufacturer Recommended): Matches all core electrical parameters with identical capacitance, tolerance, and lead spacing. Voltage rating of 350 V exceeds the original 315 V requirement. Physical dimensions remain compatible with 0.295" lead spacing and 0.709" case diameter, though height is reduced to 1.043" (26.50 mm). Product status is active.

UVZ2F101MHD (Similar Alternative): Maintains identical capacitance, tolerance, voltage rating (315 V), and lead spacing. Physical dimensions are compatible with matching case diameter and lead spacing. Height is 1.457" (37.00 mm). Product status is not for new designs.

Engineering Selection Recommendations

For New Designs: The UCS2V101MHD is the recommended substitute. It carries active product status, ensuring long-term availability and supply chain stability. The higher voltage rating (350 V) provides additional design margin beyond the original 315 V specification. Extended lifetime rating of 10000 hours at 105°C improves system reliability. Height reduction to 1.043" (26.50 mm) may provide PCB layout advantages in space-constrained applications while maintaining full electrical and mechanical compatibility through identical lead spacing and case diameter.

For Legacy System Support: The UVZ2F101MHD provides dimensional and electrical compatibility with the original UPW2F101MHD, maintaining the same 315 V voltage rating and 100 µF capacitance. However, the product status of "not for new designs" and reduced lifetime rating of 2000 hours at 105°C indicate this part is suitable only for direct replacement in existing systems where supply of the original part is unavailable. The height of 1.457" (37.00 mm) closely matches the original 1.575" (40.00 mm), minimizing PCB layout modifications.

All substitute parts maintain ROHS3 compliance and are electrically and mechanically compatible with the original UPW2F101MHD within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can the UCS2V101MHD be used as a direct replacement for the UPW2F101MHD?

A: Yes. The UCS2V101MHD maintains identical capacitance (100 µF), tolerance (±20%), and lead spacing (7.50 mm). The higher voltage rating (350 V vs. 315 V) is compatible with circuits designed for 315 V operation. The reduced height (1.043" vs. 1.575") requires verification that PCB clearance is available, but the matching case diameter and lead spacing ensure mechanical fit.

Q: What is the primary difference between the UCS2V101MHD and UVZ2F101MHD?

A: The UCS2V101MHD has an active product status with a 10000-hour lifetime rating at 105°C, making it suitable for new designs. The UVZ2F101MHD carries a "not for new designs" status with a 2000-hour lifetime rating, positioning it as a legacy support option only.

Q: Are there any height restrictions when using the UCS2V101MHD?

A: The UCS2V101MHD height of 1.043" (26.50 mm) is shorter than the original UPW2F101MHD at 1.575" (40.00 mm). Verify that the PCB layout and surrounding components provide adequate clearance. The reduced height may eliminate clearance issues in some applications.

Q: Do all substitute parts maintain the same electrical performance?

A: All substitute parts share the same capacitance value (100 µF) and tolerance (±20%). The UCS2V101MHD provides higher voltage rating (350 V) and extended lifetime (10000 Hrs @ 105°C). The UVZ2F101MHD matches the original voltage rating (315 V) but has reduced lifetime (2000 Hrs @ 105°C).

Q: Are the substitute parts RoHS compliant?

A: Yes. Both UCS2V101MHD and UVZ2F101MHD are ROHS3 compliant, matching the compliance status of the original UPW2F101MHD.
