Substitute Part Grouping Explanation

Substitutes are organized based on shared electrical and mechanical parameters. The primary substitution criteria are:

Electrical Compatibility: Capacitance (470 µF) and tolerance (±20%) are fixed across all substitutes. Voltage rating is a determining factor—parts rated at 6.3 V provide direct electrical replacement, while parts rated at 25 V or 35 V offer voltage uprating suitable for circuit designs requiring increased voltage margin.

Mechanical Compatibility: Lead spacing (0.197" / 5.00 mm), diameter (0.394" / 10.00 mm), and mounting type (through hole) define the primary mechanical envelope. A subset of substitutes with different physical dimensions (lead spacing 0.098" / 2.50 mm, diameter 0.248" / 6.30 mm) are included for applications where board space is constrained.

Reliability Parameters: Lifetime ratings and operating temperature ranges vary. Parts with extended lifetimes (2000+ hours) or wider temperature ranges (-55°C ~ 105°C) offer enhanced reliability for demanding environments.

Engineering Selection Recommendations

For Direct Mechanical and Electrical Replacement (Same Voltage Rating):

UFG0J471MPM and UKW0J471MED both provide 6.3 V rated performance with identical lead spacing (0.197" / 5.00 mm) and diameter (0.394" / 10.00 mm) to the original part. However, UFG0J471MPM uses a shorter height of 0.551" (14.00 mm) compared to the original 0.787" (20.00 mm), which may offer board space advantages but requires PCB layout verification. Both are obsolete products. UFW0J471MED offers extended lifetime (2000 Hrs @ 85°C) but employs a compact form factor (0.248" Dia / 6.30 mm, 0.433" Height) incompatible with the original footprint.

For Higher Voltage Margin and Extended Reliability:

Parts rated at 25 V or 35 V provide voltage uprating above the original 6.3 V specification. Panasonic EEU-EB1V471 (35 V, 10000 Hrs @ 105°C, Active product status) and EEU-FC1V471 (35 V, 3000 Hrs @ 105°C, Active, AEC-Q200 rated, -55°C ~ 105°C operating range) are actively manufactured. EEU-FC1V471 carries AEC-Q200 automotive qualification and is suitable for temperature-sensitive or mission-critical applications. Both maintain mechanical compatibility (0.197" lead spacing, 0.394" diameter) with the original design envelope. Height differences (0.866" for EEU-EB1V471 and 0.787" for EEU-FC1V471) require board layout validation.

Nichicon UPJ1E471MPD (25 V, 5000 Hrs @ 105°C, Not For New Designs) and Nichicon UHE1V471MPD (35 V, 7000 Hrs @ 105°C, Not For New Designs) provide extended lifetime performance but are not recommended for new design implementations. Vishay Sprague 515D477M035CG6AE3 (35 V, 2000 Hrs @ 85°C) is obsolete and offers no manufacturing advantage over active alternatives.

Compliance Considerations:

All parts listed maintain ROHS3 compliance and EAR99 ECCN classification consistent with the original component. Panasonic EEU-FC1V471 is the only part carrying AEC-Q200 qualification, making it the optimal choice for automotive or safety-critical applications.

Frequently Asked Questions (FAQ)

Q: Can I use a 25 V or 35 V rated capacitor in a circuit designed for 6.3 V?

A: Yes. Higher voltage ratings provide overvoltage protection and are electrically compatible in circuits with 6.3 V maximum operating voltage. The part will function correctly and offer increased voltage margin. Physical dimensions and PCB footprint compatibility must be verified independently.

Q: What is the difference between the Panasonic EEU-EB1V471 and EEU-FC1V471?

A: Both are 470 µF, 35 V parts with identical lead spacing and diameter. EEU-EB1V471 offers superior lifetime (10000 Hrs @ 105°C) but operates to -40°C minimum. EEU-FC1V471 has wider temperature range (-55°C ~ 105°C), carries AEC-Q200 automotive qualification, and 3000 Hrs @ 105°C lifetime. EEU-FC1V471 is preferred for automotive, military, or temperature-extreme applications.

Q: Why are UFW0J471MED and UKW0J471MED listed as substitutes if their physical dimensions differ significantly?

A: These parts share identical electrical specifications (470 µF, 6.3 V, ±20%) and are included for applications where board space permits compact form factor installation. However, the original PCB footprint (lead spacing 0.197" / 5.00 mm, diameter 0.394" / 10.00 mm) is incompatible with these compact variants (lead spacing 0.098" / 2.50 mm, diameter 0.248" / 6.30 mm). Board redesign is required for their use.

Q: What does "Product Status: Active" mean compared to "Obsolete" or "Not For New Designs"?

A: Active status indicates the part is currently manufactured and recommended for new design implementations. Obsolete status indicates discontinuation with no manufacturing resumption expected. Not For New Designs indicates the part remains available but the manufacturer does not recommend it for circuits not yet in production. For long-term supply chain stability, Active parts (Panasonic EEU-EB1V471 and EEU-FC1V471) are preferred.

Q: Are all listed substitutes RoHS compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance consistent with the original RFS-6V471MH5#5 specification.
