Substitute Part Grouping Explanation

Substitution for the UPM1H331MPD is determined by strict equivalence across the following parameters:

Primary Equivalence Criteria:

Capacitance: 330 µF (exact match required)
Voltage Rating: 50 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)

Secondary Compatibility Parameters:

Operating Temperature Range: -55°C ~ 105°C (exact match required)
Lead Spacing: 0.197" (5.00mm) (exact match required for direct PCB compatibility)
Diameter: 0.394" (10.00mm) (exact match required for mechanical fit)
Height: 1.319" (34.60mm) maximum (substitutes must not exceed this dimension)
Lifetime @ Temperature: 5000 Hrs @ 105°C minimum (equal or greater acceptable)

Substitutes are grouped into two categories:

Direct Substitutes (Identical Footprint): Parts with matching lead spacing (5.00mm), diameter (10.00mm), and height within specification. These include UPJ1H331MPD, UPW1H331MPD, EEU-FC1H331, EEU-FC1H331B, ELXY500ELL331MJ30S, and ELXZ500ELL331MJ25S.

Similar Substitutes (Different Footprint): Parts with matching electrical specifications but different mechanical dimensions. These include UPJ1H331MHD6 and UPM1H331MHD6, which have larger lead spacing (7.50mm) and different can dimensions. These require PCB layout modification and are suitable only when mechanical constraints permit.

Engineering Selection Recommendations

For Direct PCB Compatibility (No Layout Modification Required):

Select from parts with matching lead spacing (5.00mm) and diameter (10.00mm): UPJ1H331MPD, UPW1H331MPD, EEU-FC1H331, EEU-FC1H331B, ELXY500ELL331MJ30S, or ELXZ500ELL331MJ25S. Among these, EEU-FC1H331, EEU-FC1H331B, ELXY500ELL331MJ30S, and ELXZ500ELL331MJ25S carry Active product status and AEC-Q200 automotive qualification, providing the longest supply assurance and compliance continuity.

For Automotive Applications:

Parts with AEC-Q200 rating are UPM1H331MPD, UPM1H331MHD6, EEU-FC1H331, EEU-FC1H331B, ELXY500ELL331MJ30S, ELXY500ELL331MK20S, and ELXZ500ELL331MJ25S. Among active products, EEU-FC1H331, EEU-FC1H331B, ELXY500ELL331MJ30S, ELXY500ELL331MK20S, and ELXZ500ELL331MJ25S are recommended.

For Extended Thermal Life:

ELXY500ELL331MK20S offers 7000 hours at 105°C, exceeding the 5000-hour specification of the main part. This part is Active status with AEC-Q200 rating but has different mechanical dimensions (0.492" diameter, 0.846" height) requiring PCB layout verification.

For Reduced Height Constraint Applications:

UPW1H331MPD (0.787" height) and EEU-FC1H331 (0.787" height) provide the lowest profile among direct footprint substitutes. Both are suitable for space-constrained designs.

For Nichicon-Only Supply Chain Requirements:

UPJ1H331MPD is the closest Nichicon equivalent with identical electrical specifications and compatible footprint, though it lacks AEC-Q200 rating and is marked "Not For New Designs."

Frequently Asked Questions (FAQ)

Q: Can UPJ1H331MPD be used as a direct replacement for UPM1H331MPD?

A: UPJ1H331MPD is electrically equivalent with matching capacitance, voltage, tolerance, and thermal specifications. It has identical lead spacing (5.00mm) and diameter (10.00mm), making it mechanically compatible. However, it is 0.020" shorter (33.00mm vs. 34.60mm) and lacks AEC-Q200 automotive qualification. Verify application requirements before substitution.

Q: What is the difference between EEU-FC1H331 and EEU-FC1H331B?

A: Both parts are electrically and mechanically identical with matching capacitance, voltage, impedance, and ripple current specifications. The primary difference is packaging: EEU-FC1H331 is supplied in Bulk, while EEU-FC1H331B is supplied in Cut Tape (CT). EEU-FC1H331B is 0.079" taller (22.00mm vs. 20.00mm). Both carry Active status and AEC-Q200 rating.

Q: Can parts with 7.50mm lead spacing (UPJ1H331MHD6, UPM1H331MHD6) be used as substitutes?

A: These parts are electrically equivalent but have different mechanical dimensions. Lead spacing is 7.50mm instead of 5.00mm, and the can diameter is 0.630" instead of 0.394". Direct PCB substitution is not possible without layout modification. Use only when PCB design permits the larger footprint.

Q: Why do some substitutes have different heights?

A: Height variation occurs due to different internal construction and manufacturing processes among manufacturers. All listed substitutes meet or exceed the 5000-hour thermal life requirement at 105°C. Verify available PCB clearance before selecting parts with heights exceeding 1.319".

Q: Which substitute offers the best long-term supply assurance?

A: EEU-FC1H331, EEU-FC1H331B, ELXY500ELL331MJ30S, ELXY500ELL331MK20S, and ELXZ500ELL331MJ25S all carry Active product status, indicating ongoing manufacturing and supply availability. These are preferred over "Not For New Designs" parts for new designs and long-term production.

Q: Are all substitutes RoHS3 compliant?

A: All listed substitutes are ROHS3 compliant. All are also REACH affected or unaffected as specified in their individual datasheets. Verify REACH compliance status for your specific supply chain requirements.

Q: What is the significance of impedance differences among substitutes?

A: Impedance values range from 54 mOhms to 90 mOhms across the substitute list. Lower impedance generally indicates better high-frequency performance. For applications sensitive to impedance characteristics, verify the specific impedance requirement before substitution.

Q: Can EEU-FC1H331L be used as a substitute despite its 3000-hour lifetime?

A: EEU-FC1H331L has a 3000-hour thermal life at 105°C, which is lower than the UPM1H331MPD specification of 5000 hours. This part is suitable only for applications with less stringent thermal life requirements. It is not recommended as a direct substitute for the main part.
