Substitute Part Grouping Explanation
Substitute parts are organized into three categories based on substitution logic:
Direct Equivalents (Same Voltage, Same Lifetime Temperature):
- ECA-2VHG100 (Panasonic): Identical electrical specifications with automotive-grade AEC-Q200 rating and extended operating temperature to 105°C. Suitable for direct replacement in applications requiring higher temperature margin.
- UCS2V100MPD (Nichicon): Matches 350 V rating with extended lifetime (8000 Hrs @ 105°C) and wider operating temperature (-40°C to 105°C). Physical dimensions vary slightly in height (21.50 mm vs 22.00 mm).
Voltage Upgrades (Higher Voltage Rating):
- ECA-2GM100B (Panasonic): 400 V rated, same series family, identical physical footprint and lifetime at 85°C.
- EEU-EE2G100 (Panasonic): 400 V rated with extended lifetime (8000 Hrs @ 105°C) and higher ripple current capability.
- EEU-EE2W100U (Panasonic): 450 V rated with extended lifetime (8000 Hrs @ 105°C).
- 106CKE400M (Cornell Dubilier): 400 V rated, different manufacturer, specified ESR value (33.16 Ohm @ 120 Hz).
- 106CKE450MLU (Cornell Dubilier): 450 V rated with same ESR specification.
- 106CKS450MLU (Cornell Dubilier): 450 V rated, different series with MSL rating.
- 400BXC10MEFC10X20 (Rubycon): 400 V rated with extended lifetime (10000 Hrs @ 105°C).
- 450BXC10MEFC10X20 (Rubycon): 450 V rated with extended lifetime (10000 Hrs @ 105°C).
Substitution is permitted when circuit design allows higher voltage rating. All substitute parts maintain identical capacitance (10 µF), tolerance (±20%), polarization (Polar), and through-hole radial can package with 5.00 mm lead spacing.

Engineering Selection Recommendations
For Direct Replacement (Same Electrical Performance): ECA-2VHG100 is the primary direct substitute, offering identical 350 V rating with automotive-grade AEC-Q200 certification and extended operating temperature to 105°C. UCS2V100MPD provides equivalent 350 V performance with extended lifetime (8000 Hrs @ 105°C) and wider temperature range (-40°C to 105°C), though physical height is 0.020" shorter.
For Voltage Margin Enhancement: When circuit design permits higher voltage rating, ECA-2GM100B (400 V) or EEU-EE2G100 (400 V with 8000 Hrs @ 105°C) provide direct footprint compatibility. For maximum voltage headroom, EEU-EE2W100U (450 V) or Rubycon 450BXC10MEFC10X20 (450 V with 10000 Hrs @ 105°C) are suitable.
For Extended Lifetime Requirements: EEU-EE2G100 and EEU-EE2W100U (Panasonic EE series) offer 8000 hours at 105°C. Rubycon BXC series (400BXC10MEFC10X20 and 450BXC10MEFC10X20) provide maximum lifetime rating of 10000 hours at 105°C.
For Automotive Applications: ECA-2VHG100 carries AEC-Q200 rating and is specified for automotive use.
All substitute parts maintain ROHS3 compliance and through-hole radial can package configuration with 5.00 mm lead spacing.
Frequently Asked Questions (FAQ)
Q: Can ECA-2VHG100 replace ECA-2VM100 in all applications? A: Yes. ECA-2VHG100 is electrically equivalent at 350 V, 10 µF with identical tolerance and polarization. It offers extended operating temperature (105°C vs 85°C) and automotive-grade certification. Physical dimensions are identical.
Q: What is the difference between direct equivalents and voltage upgrades? A: Direct equivalents maintain the same 350 V rating as ECA-2VM100. Voltage upgrades (400 V or 450 V) provide higher voltage margin and are suitable only when circuit design allows higher voltage rating. All maintain identical capacitance and tolerance.
Q: Are there physical compatibility concerns with substitute parts? A: Most substitutes maintain identical 10.00 mm diameter and 22.00 mm height. UCS2V100MPD, 106CKE400M, 106CKE450MLU, and 106CKS450MLU have 21.50 mm height (0.020" shorter). All maintain 5.00 mm lead spacing for PCB compatibility.
Q: Which substitute offers the longest operational lifetime? A: Rubycon BXC series (400BXC10MEFC10X20 and 450BXC10MEFC10X20) provide 10000 hours at 105°C. Panasonic EE series (EEU-EE2G100 and EEU-EE2W100U) provide 8000 hours at 105°C.
Q: What is the significance of ripple current ratings? A: Ripple current capacity determines the maximum AC current the capacitor can handle without exceeding temperature limits. Higher ripple current ratings indicate better performance in high-frequency switching applications. Panasonic EE series and Nichicon UCS series show higher ripple current capability than the original ECA-2VM100.
Q: Are all substitutes RoHS compliant? A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of ECA-2VM100.
Q: Can I use a 450 V rated capacitor in place of a 350 V rated capacitor? A: Yes, when circuit design permits. Higher voltage rating provides additional safety margin. However, verify that the application does not require the specific electrical characteristics of the original 350 V part.
