Key Parameters

Substitute Part Grouping Explanation

Substitution of the UFW1C331MPD is determined by strict equivalence in the following parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 0.138" (4.60mm) (exact match required for PCB compatibility)
• Physical Dimensions: 0.315" Dia (8.00mm) and 0.453" Height (exact match required for mechanical fit)

Substitute parts are grouped into three categories based on performance characteristics:

Upgrade Parts offer extended lifetime or expanded operating temperature ranges while maintaining identical electrical and mechanical specifications.

Similar Parts maintain core electrical parameters but differ in physical dimensions, lead spacing, or performance ratings, requiring PCB layout verification.

Parametric Equivalents match all critical electrical and mechanical parameters with identical form factor and footprint.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Form Factor and Footprint):

UKW1C331MPD and UHE1C331MPD are parametric equivalents to UFW1C331MPD with identical lead spacing (0.138" / 4.60mm), physical dimensions (0.315" Dia / 8.00mm), and height (0.453" / 11.50mm). Both parts are ROHS3 compliant. UHE1C331MPD offers extended lifetime (7000 Hrs @ 105°C) and expanded operating temperature range (-40°C ~ 105°C). UPW1C331MPD provides intermediate lifetime (3000 Hrs @ 105°C) with extended low-temperature capability (-55°C ~ 105°C).

For Cross-Manufacturer Compatibility:

EEU-FC1C331 from Panasonic Electronic Components is an active product with identical electrical and mechanical specifications. This part carries AEC-Q200 automotive qualification and is ROHS3 compliant. It provides extended operating temperature range (-55°C ~ 105°C) and 2000 hours lifetime at 105°C.

For Legacy Systems:

UFG1C331MPM is classified as Obsolete and features different lead spacing (0.197" / 5.00mm) and larger physical dimensions (0.394" Dia / 10.00mm, 0.689" Height). This part is not suitable for direct PCB replacement without layout modification.

Frequently Asked Questions (FAQ)

Q: Can UFW1C331MPD be replaced with UKW1C331MPD?

A: Yes. UKW1C331MPD is a parametric equivalent with identical capacitance (330 µF), voltage rating (16 V), tolerance (±20%), lead spacing (0.138" / 4.60mm), and physical dimensions (0.315" Dia / 8.00mm, 0.453" Height). Both are ROHS3 compliant and rated for 2000 hours at 85°C. Direct PCB substitution is possible without layout modification.

Q: What is the difference between UHE1C331MPD and UPW1C331MPD?

A: Both parts maintain identical electrical and mechanical specifications to UFW1C331MPD. UHE1C331MPD offers 7000 hours lifetime at 105°C with operating range -40°C ~ 105°C. UPW1C331MPD provides 3000 hours lifetime at 105°C with extended low-temperature capability (-55°C ~ 105°C). Selection depends on thermal environment and required operational lifespan.

Q: Is EEU-FC1C331 a suitable replacement?

A: Yes. EEU-FC1C331 from Panasonic is an active product with identical capacitance, voltage, tolerance, lead spacing, and physical dimensions. It is ROHS3 compliant and carries AEC-Q200 automotive qualification. Operating temperature range is -55°C ~ 105°C with 2000 hours lifetime at 105°C. Direct PCB substitution is possible.

Q: Why is UFG1C331MPM not recommended as a direct replacement?

A: UFG1C331MPM has different lead spacing (0.197" / 5.00mm versus 0.138" / 4.60mm) and larger physical dimensions (0.394" Dia / 10.00mm versus 0.315" Dia / 8.00mm). PCB layout modification is required for mechanical and electrical fit. Additionally, this part is classified as Obsolete.

Q: What parameters must match for direct PCB substitution?

A: Lead spacing, physical diameter, and seated height must match exactly. For UFW1C331MPD, these are 0.138" (4.60mm) lead spacing, 0.315" Dia (8.00mm), and 0.453" (11.50mm) height. Capacitance, voltage rating, tolerance, and polarization must also be identical. UKW1C331MPD, UHE1C331MPD, UPW1C331MPD, and EEU-FC1C331 meet all these requirements.
