Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UPW1E331MPH6 is determined by strict equivalence across the following parameters: capacitance (330 µF), voltage rating (25 V), tolerance (±20%), polarization (polar), mounting type (through hole), and package type (radial, can). Physical dimensions and lead spacing must remain within the specified tolerances to ensure PCB compatibility. Lifetime rating at 105°C and ripple current specifications may vary within acceptable engineering margins for general-purpose applications.

Substitute parts are grouped into three categories:

Direct Equivalent: Identical electrical and mechanical specifications with active product status and improved compliance.

Similar Equivalent: Matching core electrical parameters with variations in physical dimensions, lead spacing, or lifetime ratings that remain functionally compatible.

Upgrade Equivalent: Parts meeting all core parameters with enhanced certifications (AEC-Q200) and automotive-grade reliability suitable for demanding applications.

Parameter Comparison

Engineering Selection Recommendations

UPW1E331MPD6 (Nichicon): Direct replacement for UPW1E331MPH6. Identical electrical and mechanical specifications with active product status and ROHS3 compliance. Recommended as primary substitute for direct PCB compatibility without design modification.

ELXZ250ELL331MH15D (Chemi-Con): Functionally equivalent with identical physical dimensions and lead spacing. Carries AEC-Q200 automotive qualification and active product status. Suitable for applications requiring automotive-grade reliability and compliance certifications.

EEU-FC1E331L (Panasonic Electronic Components): Matches core electrical parameters with identical physical footprint. Carries AEC-Q200 automotive qualification and active product status. Lifetime rating of 2000 hours at 105°C is lower than the original specification; suitable for applications with reduced thermal stress requirements.

UPW1E331MPD (Nichicon): Similar electrical performance with extended 5000-hour lifetime at 105°C. Physical dimensions differ (larger can size and lead spacing); PCB layout modification required. Product status is "Not For New Designs"; use only for legacy system maintenance where footprint accommodation is feasible.

EEU-FC1E331 (Panasonic Electronic Components): Matches electrical specifications with extended 3000-hour lifetime. Physical dimensions differ (larger can size and lead spacing); PCB layout modification required. Active product status with ROHS3 compliance and AEC-Q200 automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can UPW1E331MPD6 be used as a direct drop-in replacement for UPW1E331MPH6?

A: Yes. UPW1E331MPD6 maintains identical capacitance (330 µF), voltage rating (25 V), tolerance (±20%), lifetime (3000 Hrs @ 105°C), physical dimensions (0.315" Dia × 0.591" height), and lead spacing (0.138" / 4.60mm). No PCB modification is required.

Q: What is the difference between parts with 0.138" and 0.197" lead spacing?

A: Lead spacing determines the distance between component pins on the PCB. Parts with 0.138" (4.60mm) spacing fit the original UPW1E331MPH6 footprint. Parts with 0.197" (5.00mm) spacing require PCB layout modification and cannot be used without design changes.

Q: Why does EEU-FC1E331L have a lower lifetime rating (2000 Hrs vs. 3000 Hrs)?

A: Lifetime rating reflects the expected operational duration at maximum rated temperature (105°C). Lower lifetime ratings indicate reduced thermal stress capability. EEU-FC1E331L is suitable for applications where ambient temperatures remain below maximum operating conditions.

Q: Are automotive-qualified parts (AEC-Q200) necessary for general-purpose applications?

A: AEC-Q200 certification indicates enhanced reliability testing and quality standards. For general-purpose applications, automotive-qualified parts provide additional margin but are not mandatory. Selection depends on application reliability requirements and environmental conditions.

Q: Can parts with different physical dimensions be used interchangeably?

A: No. Physical dimensions and lead spacing determine PCB footprint compatibility. Parts with different dimensions (such as UPW1E331MPD or EEU-FC1E331) require PCB layout modification and cannot be used as direct replacements without design changes.

Q: What does "Not For New Designs" product status mean?

A: This status indicates the manufacturer no longer recommends the part for new product development. The part remains available for legacy system support and maintenance. For new designs, select parts with "Active" product status.
