Engineering Selection Recommendations

Active Product Status Priority: UCS2W100MHD1TO (Nichicon), 450BXC10MEFCG412.5X20 (Rubycon), ECA-2WHG100B (Panasonic), EEU-EB2W100B (Panasonic), and ECA-2WM100B (Panasonic) are all Active products suitable for new designs, whereas the original UVR2W100MHD1TO is Not For New Designs.

Extended Lifetime Options: UCS2W100MHD1TO and 450BXC10MEFCG412.5X20 provide 10000 and 12000 hour lifetimes respectively at elevated temperatures (105°C), compared to the original 2000 hour rating at 85°C.

Voltage Margin: UCY2H100MHD1TO offers 500 V rating, providing additional voltage margin over the 450 V requirement.

Compliance: All substitute parts are ROHS3 compliant and maintain the same mechanical footprint compatibility with the original part.

Parametric Match: ECA-2WM100B provides an exact parametric match with identical lifetime (2000 Hrs @ 85°C) and operating temperature range (-25°C to 85°C) while maintaining Active product status.

Frequently Asked Questions (FAQ)

Q: Can UCY2H100MHD1TO be used as a direct replacement for UVR2W100MHD1TO?

A: Yes. UCY2H100MHD1TO meets all substitution criteria with matching capacitance (10 µF), tolerance (±20%), lead spacing (5.00 mm), diameter (12.50 mm), and mounting type (Through Hole). The 500 V rating exceeds the 450 V requirement. Height differs by 0.020" (0.50 mm), which does not affect PCB compatibility for through-hole applications.

Q: What is the difference between UCA2W100MHD1TO and UCS2W100MHD1TO?

A: Both are Nichicon 10 µF, 450 V radial capacitors with identical mechanical dimensions. UCA2W100MHD1TO is Not For New Designs with 12000 hour lifetime at 105°C. UCS2W100MHD1TO is Active with 10000 hour lifetime at 105°C. UCS2W100MHD1TO is recommended for new designs.

Q: Are all substitute parts mechanically compatible with the original footprint?

A: All substitute parts maintain the same lead spacing (5.00 mm) and diameter (12.50 mm). Height variations range from 0.846" to 0.866" (21.50 mm to 22.00 mm). These minor height differences do not affect PCB layout compatibility for radial through-hole mounting.

Q: Which substitute offers the best reliability for extended operation?

A: 450BXC10MEFCG412.5X20 (Rubycon) and UCA2W100MHD1TO (Nichicon) both provide 12000 hour lifetime ratings at 105°C. 450BXC10MEFCG412.5X20 is Active product status, making it suitable for new designs.

Q: Is ECA-2WM100B a suitable replacement if operating temperature does not exceed 85°C?

A: Yes. ECA-2WM100B matches the original UVR2W100MHD1TO in lifetime (2000 Hrs @ 85°C) and operating temperature range (-25°C to 85°C) while maintaining Active product status and full mechanical compatibility.

Q: What packaging options are available for these substitutes?

A: Most substitutes are supplied in Cut Tape (CT) packaging. ECA-2WHG100B is supplied in Tape & Box (TB) packaging. Packaging selection does not affect electrical or mechanical performance.
