Substitute Part Grouping Explanation

Substitution of the RFS-6V102MI5#5 is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Capacitance: 1000 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 6.3 V minimum (equal or higher voltage acceptable)
• Polarization: Polar (exact match required)
• Lead Spacing: 0.197" (5.00 mm) (exact match required)
• Case Diameter: 0.492" (12.50 mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial, Can (exact match required)

Substitution Categories:

Category 1: Direct Equivalents (Same Voltage Rating - 6.3 V) Parts meeting all primary criteria with identical 6.3 V voltage rating and compatible physical dimensions:

• UFG0J102MPM (Nichicon UFG series)
• UFW0J102MPD (Nichicon UFW series)
• UKW0J102MPD (Nichicon UKW series)

Category 2: Upgraded Substitutes (Higher Voltage Rating) Parts meeting all primary criteria with voltage ratings higher than 6.3 V. These provide enhanced voltage margin and are electrically compatible in circuits designed for 6.3 V operation:

• UFW1V102MHD (Nichicon UFW series, 35 V rating)
• UKW1V102MHD (Nichicon UKW series, 35 V rating)
• UPA1V102MHD (Nichicon UPA series, 35 V rating)
• UHE1E102MHD6 (Nichicon UHE series, 25 V rating)

Category 3: Similar Parts (Different Physical Dimensions) Parts with matching capacitance, tolerance, and polarization but differing in case diameter, height, or lead spacing. These require mechanical re-evaluation:

• EEU-EB1E102 (Panasonic EB-A series, 25 V, 0.866" height)
• EEU-FC1E102 (Panasonic FC series, 25 V, automotive rated)
• EKZE250ELL102MK20S (Chemi-Con KZE series, 25 V, 0.846" height)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Footprint and Voltage):

UFW1V102MHD and UKW1V102MHD are the preferred direct substitutes. Both maintain the exact physical dimensions (0.492" diameter, 0.787" height, 0.197" lead spacing) and are compatible with the original 6.3 V circuit design due to their higher 35 V rating. These parts provide improved reliability with 2000 hours lifetime at 85°C compared to the original 1000 hours. However, both are classified as "Not For New Designs," indicating they are suitable for legacy system support only.

For New Designs with Enhanced Performance:

UPA1V102MHD is the recommended choice for new applications. This Nichicon part maintains identical physical dimensions and electrical specifications (1000 µF, ±20% tolerance) while offering:

• Active product status, ensuring long-term availability
• 35 V rating providing voltage margin above the 6.3 V requirement
• Extended lifetime of 5000 hours at 105°C
• Operating temperature range of -55°C to 105°C
• ROHS3 compliance and REACH affected status

For Applications Requiring Higher Temperature Performance:

UHE1E102MHD6 and EEU-EB1E102 both provide 10000 hours lifetime at 105°C, suitable for demanding thermal environments. Both maintain the 0.492" diameter and 0.197" lead spacing. UHE1E102MHD6 matches the original height exactly (0.787"), while EEU-EB1E102 is slightly taller (0.866"). EEU-EB1E102 is active and recommended for new designs.

For Automotive Applications:

EEU-FC1E102 is the only part in this list with AEC-Q200 automotive qualification. It maintains exact physical dimensions and provides 5000 hours lifetime at 105°C with active product status.

Compliance Considerations:

All substitute parts listed are ROHS3 compliant. The original RFS-6V102MI5#5 is REACH unaffected, while UPA1V102MHD, UHE1E102MHD6, and EEU-FC1E102 are REACH affected. Verify REACH compliance requirements for your specific application before selection.

Frequently Asked Questions (FAQ)

Q: Can I use a 35 V rated capacitor in place of the 6.3 V RFS-6V102MI5#5?

A: Yes. A higher voltage rating is electrically compatible in circuits designed for lower voltage operation. The 35 V parts (UFW1V102MHD, UKW1V102MHD, UPA1V102MHD) will function correctly in a 6.3 V circuit. The higher voltage rating provides additional safety margin and does not negatively affect circuit performance.

Q: What is the difference between "Not For New Designs" and "Active" product status?

A: "Active" status indicates the manufacturer continues production and supports the part for new applications. "Not For New Designs" indicates the part is in production but the manufacturer recommends against using it in new designs, typically due to planned obsolescence or availability concerns. For legacy system repairs, "Not For New Designs" parts are acceptable. For new product development, select "Active" status parts.

Q: Do all substitute parts have the same physical dimensions as the original?

A: No. While most maintain the 0.492" diameter and 0.197" lead spacing, some differ in height. UFW0J102MPD and UKW0J102MPD have smaller case diameters (0.315") and different lead spacing (0.138"), requiring PCB layout changes. EEU-EB1E102 and EKZE250ELL102MK20S have slightly greater heights (0.866" and 0.846" respectively) compared to the original 0.787". Verify mechanical fit before selection.

Q: Which substitute offers the best long-term reliability?

A: UHE1E102MHD6 and EEU-EB1E102 both offer 10000 hours lifetime at 105°C, the highest rating in this list. EEU-EB1E102 is preferred for new designs due to active product status. UPA1V102MHD offers a balanced option with 5000 hours at 105°C and active status.

Q: Are there ripple current differences between the original and substitutes?

A: Yes. The original RFS-6V102MI5#5 is rated for 710 mA ripple current at 120 Hz. Upgraded substitutes with higher voltage ratings typically support higher ripple currents (1.1 A to 1.4 A at 120 Hz). Verify your circuit's ripple current requirements do not exceed the selected substitute's rating.

Q: What does "Impedance" mean in the parameter table?

A: Impedance (measured in milliohms) represents the equivalent series resistance (ESR) at a specific frequency. Lower impedance values indicate better high-frequency performance. Parts with lower impedance (21-29 mOhms) provide superior performance in applications with high-frequency ripple current or noise-sensitive circuits.

Q: Can I substitute a 25 V rated part for the 6.3 V original?

A: Yes. A 25 V rated capacitor is electrically compatible in a 6.3 V circuit. Parts such as UHE1E102MHD6, EEU-EB1E102, EEU-FC1E102, and EKZE250ELL102MK20S all provide this capability with improved reliability characteristics. Verify mechanical fit, as some have different heights.

Q: Which substitute is best for audio applications?

A: The original RFS-6V102MI5#5 is specified for audio applications. UFG0J102MPM, UFW0J102MPD, and UKW0J102MPD are also audio-rated. However, UPA1V102MHD, while rated for general purpose applications, maintains identical electrical specifications and physical dimensions with active product status, making it suitable for audio use in new designs.

Q: Is REACH compliance important for my application?

A: REACH compliance is required for products sold in the European Union. The original part is REACH unaffected. If your product is distributed in the EU, select REACH-compliant alternatives or verify exemptions. UPA1V102MHD and UHE1E102MHD6 are REACH affected, requiring additional documentation. EEU-FC1E102 status should be verified with the manufacturer.
