Package Type: Radial, Can (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Diameter: 0.492" (12.50 mm) (exact match required)
Mounting Type: Through Hole (exact match required)

Engineering Selection Recommendations

Parametric Equivalent (Same Series Variant): UVR2W100MHD1CV is a direct variant within the same UVR series with identical electrical specifications and physical dimensions. This part maintains Active product status and is suitable for direct replacement where the original part number is unavailable.

Upgrade Options with Extended Temperature Range: UBT2W100MHD8 extends the operating temperature to 125°C and maintains Active status, suitable for applications requiring enhanced thermal performance. UCS2W100MHD and UCA2W100MHD offer extended lifetime ratings (10000 and 12000 hours respectively) at 105°C, with UCS2W100MHD maintaining Active status. UCY2H100MHD provides both extended temperature range (-40°C to 105°C) and higher voltage rating (500 V) with Active status.

Alternative Manufacturers: 450BXC10MEFC12.5X20 (Rubycon) and 450LLE10MEFC12.5X20 (Rubycon) provide equivalent electrical specifications with extended lifetime ratings (12000 and 20000 hours respectively) and Active product status. ESMG451ELL100MK20S (Chemi-Con) matches the original specifications with Active status. 106CKE450M and 106CKS500MTJG (Cornell Dubilier / Illinois Capacitor) are Active alternatives with specified ESR values.

Compliance Considerations: All listed substitutes maintain ROHS3 compliance. UCY2H100MHD and 106CKS500MTJG carry REACH Affected status, while remaining parts are REACH Unaffected. All parts are classified under ECCN EAR99 and HTSUS 8532.22.0020.

Frequently Asked Questions (FAQ)

Q: Can UVR2W100MHD be replaced with a higher voltage rating capacitor? A: Yes. Capacitors with 500 V or higher ratings (such as UCY2H100MHD or 106CKS500MTJG) are electrically compatible substitutes, as voltage rating is a maximum specification. The 10 µF capacitance, ±20% tolerance, radial can package, and through-hole mounting must remain unchanged.

Q: What is the difference between Upgrade and Direct substitute categories? A: Upgrade substitutes offer enhanced performance characteristics such as extended temperature range, longer lifetime ratings, or higher voltage ratings while maintaining the same base capacitance and package. Direct substitutes from alternative manufacturers match the original electrical and mechanical specifications without performance enhancement.

Q: Are height variations acceptable for board-level substitution? A: Height variations within ±0.020" are acceptable for through-hole mounted components. The UVR2W100MHD height of 0.866" can accommodate substitutes with heights of 0.846" to 0.886". Verify clearance in your specific application before substitution.

Q: Which substitute offers the longest operational lifetime? A: 450LLE10MEFC12.5X20 provides 20000 hours at 105°C, the highest lifetime rating among all listed substitutes. This extended lifetime may be beneficial for applications requiring maximum component reliability.

Q: Is UCA2W100MHD suitable for new designs despite Obsolete status? A: No. Components marked Obsolete should not be selected for new designs. Active alternatives such as UCS2W100MHD or 450LLE10MEFC12.5X20 are recommended for new applications.

Q: What is the impact of different ripple current ratings? A: Ripple current capacity determines the maximum AC current the capacitor can handle without exceeding temperature limits. Substitutes with equal or higher ripple current ratings are compatible. Verify your application's ripple current requirements against the selected substitute's specifications.

Q: Can I use 106CKS500MTJG as a direct replacement for UVR2W100MHD? A: 106CKS500MTJG is electrically compatible with identical capacitance, tolerance, and package specifications. The 500 V rating provides additional voltage margin. However, verify MSL (Moisture Sensitivity Level) requirements for your assembly process, as this part carries MSL 1 classification.
