Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence in the following parameters:

Capacitance: 1000 µF (exact match required)
Voltage Rating: 35 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Operating Temperature Range: -55°C to 105°C minimum (equal or wider range acceptable)

All substitute parts listed meet these core electrical and mechanical parameters. Variations in lifetime rating, impedance, ripple current capability, and physical dimensions (within package constraints) do not disqualify substitution but may affect performance characteristics in specific applications.

Engineering Selection Recommendations

Direct Substitutes (Nichicon Series): UPA1V102MHD1TO and UPW1V102MHD1TO are direct Nichicon alternatives. UPA1V102MHD1TO is Active status with improved 5000-hour lifetime and lower impedance. UPW1V102MHD1TO offers extended 7000-hour lifetime but retains "Not For New Designs" status.

Upgraded Alternatives (Multi-Manufacturer): 860080578021 (Würth Elektronik, WCAP-ATLI) and 860160578032 (Würth Elektronik, WCAP-ATLL) are Active products with superior impedance characteristics. 860080578021 provides 5000-hour lifetime with 19 mOhms impedance; 860160578032 extends to 7000 hours.

Automotive-Qualified Options: EEU-FC1V102B (Panasonic, FC series) and MAL214630102E3 (Vishay, 146 RTI series) carry AEC-Q200 certification, suitable for automotive applications. MAL214630102E3 extends operating temperature to 125°C and offers 5000-hour lifetime at that elevated temperature.

Lower-Performance Alternative: ECA-1VHG102 (Panasonic, NHG-A series) is Active but rated for only 2000 hours at 105°C. Use only where reduced lifetime is acceptable or cost is the primary constraint.

Frequently Asked Questions (FAQ)

Q: Can I use UPA1V102MHD1TO as a direct replacement for UPS1V102MHD1TO? A: Yes. Both parts share identical capacitance (1000 µF), voltage rating (35 V), tolerance (±20%), lead spacing (5.00 mm), and operating temperature range (-55°C to 105°C). UPA1V102MHD1TO is Active status with improved lifetime (5000 hours vs. 3000 hours) and lower impedance (29 mOhms vs. 57 mOhms). Physical height differs (22.00 mm vs. 27.00 mm), which may affect PCB layout in space-constrained designs.

Q: What is the difference between the Würth Elektronik parts 860080578021 and 860160578032? A: Both are equivalent substitutes with identical electrical specifications. The primary difference is lifetime rating: 860080578021 is rated 5000 hours at 105°C with 19 mOhms impedance, while 860160578032 is rated 7000 hours at 105°C with 60 mOhms impedance. Select based on application lifetime requirements and acceptable impedance levels.

Q: Are the Panasonic EEU-FC1V102B and Vishay MAL214630102E3 suitable for automotive applications? A: Yes. Both carry AEC-Q200 certification. EEU-FC1V102B is rated 5000 hours at 105°C. MAL214630102E3 extends to 5000 hours at 125°C with wider operating temperature range (-55°C to 125°C), providing additional thermal margin for high-temperature automotive environments.

Q: Can I use ECA-1VHG102 as a substitute? A: ECA-1VHG102 meets all core electrical and mechanical parameters but is rated only 2000 hours at 105°C compared to the original 3000 hours. Use only in applications where reduced component lifetime is acceptable or where cost optimization justifies the trade-off.

Q: Does lead spacing affect substitution compatibility? A: All listed substitutes maintain 0.197" (5.00 mm) lead spacing, ensuring PCB footprint compatibility. Physical height varies between 0.866" and 1.063", which may require verification in space-constrained designs but does not affect electrical substitution.

Q: What does "Not For New Designs" status mean? A: This designation indicates the manufacturer has superseded the part in their product line. While the component remains functional and available, manufacturers recommend using Active-status alternatives for new designs. For legacy system maintenance and repair, "Not For New Designs" parts remain valid substitutes.
