Engineering Selection Recommendations

For Direct Replacement (Same Specifications):

UVR2W010MPD (Nichicon): Direct equivalent with ROHS3 compliance. Suitable for applications requiring Nichicon series continuity. Product status is "Not For New Designs," limiting use to legacy system maintenance.
ECA-2WM010 (Panasonic): Active product with ROHS3 compliance and identical electrical specifications. Slightly reduced height (0.492" vs 0.512") provides improved PCB layout flexibility. Recommended for new designs requiring direct electrical equivalence.
SK010M450ST (Cornell Dubilier): Active product with ROHS3 compliance. Increased height (0.531") requires PCB layout verification. Suitable where CDE component qualification is required.
105CKS450M (Cornell Dubilier / Illinois Capacitor): Active product with ROHS3 compliance and matching height profile. Suitable for applications with established Illinois Capacitor specifications.

For Enhanced Performance (Upgrade Options):

450BXC1MEFC8X11.5 (Rubycon): Upgrade option with extended lifetime (8000 Hrs @ 105°C vs 2000 Hrs @ 85°C) and higher operating temperature range (-25°C to 105°C). ROHS3 compliant. Increased height (0.531") requires PCB layout verification. Recommended for applications requiring improved thermal performance and extended service life.
ECA-2WHG010 (Panasonic): Upgrade option with extended operating temperature range (-25°C to 105°C) and higher temperature lifetime rating (2000 Hrs @ 105°C). ROHS3 compliant. Reduced height (0.492") provides PCB layout advantages. Recommended for applications with elevated ambient temperature requirements.

All substitute parts maintain ROHS3 compliance, addressing the non-compliance status of the original UVR2W010MPA.

Frequently Asked Questions (FAQ)

Q: Can UVR2W010MPA be replaced with any of these substitute parts? A: Yes, all listed parts meet the core electrical and mechanical parameters: 1 µF capacitance, 450 V rating, ±20% tolerance, polar configuration, radial can package, through-hole mounting, 0.138" lead spacing, and 0.315" case diameter. Physical height variations require PCB layout verification.

Q: What is the difference between direct equivalents and upgrade substitutes? A: Direct equivalents maintain identical lifetime and operating temperature specifications (2000 Hrs @ 85°C, -25°C to 85°C). Upgrade substitutes offer extended lifetime ratings or higher operating temperature ranges, providing improved performance for demanding applications.

Q: Does height variation affect compatibility? A: Height differences range from 0.492" to 0.531" compared to the original 0.512". While all parts fit the same lead spacing and case diameter, PCB layout and clearance requirements must be verified for each application.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed carry ROHS3 compliance, addressing the non-compliance status of the obsolete UVR2W010MPA.

Q: Which substitute is recommended for new designs? A: ECA-2WM010 (Panasonic) is recommended for new designs. It is an active product with ROHS3 compliance, identical electrical specifications, and reduced height that improves PCB layout flexibility.

Q: Which substitute offers the best thermal performance? A: 450BXC1MEFC8X11.5 (Rubycon) offers the best thermal performance with 8000 hours lifetime at 105°C and an operating range to 105°C, compared to 2000 hours at 85°C for the original part.

Q: Can I use ECA-2WHG010 in high-temperature applications? A: Yes. ECA-2WHG010 supports operating temperatures to 105°C with a 2000-hour lifetime rating at that temperature, making it suitable for elevated ambient temperature environments.

Q: What should I verify before implementing a substitute? A: Verify PCB layout clearance for height variations, confirm lead spacing compatibility (all parts use 0.138" spacing), and validate ripple current and ESR specifications for your specific circuit requirements.
