UVR2G100MHA Equivalent & Substitute Parts

Part Overview

The UVR2G100MHA is a 10 µF, 400 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete and no longer recommended for new designs. The UVR series represents an older generation of general-purpose capacitors with a 2000-hour lifetime rating at 85°C. Due to its obsolete status, identifying equivalent and substitute parts is necessary for ongoing maintenance, repair, and legacy system support where direct replacement or upgraded alternatives are required.

Substitute Part Grouping Explanation

Substitution of the UVR2G100MHA is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Direct Substitution:

Capacitance: 10 µF (exact match required)
Voltage Rating: 400 V minimum (higher voltage ratings are acceptable)
Tolerance: ±20% (matching or tighter tolerance acceptable)
Package: Radial, Can (identical form factor)
Lead Spacing: 0.197" (5.00 mm) (exact match required for PCB compatibility)
Case Diameter: 0.492" (12.50 mm) (exact match required for mechanical fit)
Height: 0.866" (22.00 mm) (exact match required for clearance)
Mounting Type: Through Hole (identical)
Polarization: Polar (identical)

Parameters Allowing Variation:

Operating Temperature Range: May be extended (e.g., -40°C ~ 105°C acceptable)
Lifetime @ Temperature: May be extended (e.g., 2000 Hrs @ 105°C or 3000 Hrs @ 105°C acceptable)
Ripple Current: May be lower or higher depending on application requirements
RoHS Status: May differ (RoHS3 Compliant acceptable for RoHS non-compliant original)

Substitute parts are grouped into three categories: Direct Manufacturer Equivalents (same series, same electrical performance), Upgrade Parts (enhanced temperature or lifetime ratings), and Similar Parts (different manufacturers with matching core specifications).

Engineering Selection Recommendations

Direct Replacement (Same Electrical Performance): UVR2G100MHD and UVR2G100MHD1AA are direct Nichicon equivalents with identical electrical specifications. UVR2G100MHD is ROHS3 compliant and represents the most straightforward replacement for the obsolete UVR2G100MHA. UVR2G100MHD1AA is active status and maintains the same performance envelope.

Upgraded Alternatives (Enhanced Temperature Rating): UAQ2G100MHD (Nichicon) and 400PX10MEFC12.5X20 (Rubycon) provide extended operating temperature range (-40°C ~ 105°C) and improved lifetime ratings (2000 Hrs @ 105°C). Both are ROHS3 compliant and active status. These are suitable for applications requiring higher temperature stability.

Higher Voltage Alternatives (Vishay Beyschlag/Draloric/BC Components): MAL214267109E3, MAL215257109E3, and MAL215267109E3 offer 450 V rating with extended lifetime ratings (2500–3000 Hrs @ 105°C). These parts are ROHS3 compliant, active status, and carry AEC-Q200 automotive qualification. Selection among these three depends on required lifetime: MAL214267109E3 (2500 Hrs @ 105°C) or MAL215257109E3 and MAL215267109E3 (3000 Hrs @ 105°C).

Alternative Manufacturer (Cornell Dubilier Electronics): SK100M400ST matches the original 400 V rating and 2000-hour lifetime but has slightly larger case dimensions (0.512" diameter, 0.906" height) and narrower operating temperature range (-25°C ~ 85°C). This part is suitable only if PCB layout permits the larger footprint and lower temperature minimum is acceptable.

Frequently Asked Questions (FAQ)

Q: Can I use a 450 V rated capacitor in place of the 400 V UVR2G100MHA? A: Yes. Higher voltage ratings are acceptable substitutes. The 450 V Vishay parts (MAL214267109E3, MAL215257109E3, MAL215267109E3) are direct electrical substitutes with identical capacitance, tolerance, and package dimensions. The higher voltage rating provides additional safety margin.

Q: What is the difference between UVR2G100MHD and UAQ2G100MHD? A: Both are Nichicon 10 µF, 400 V radial capacitors with identical package dimensions. The key difference is operating temperature range and lifetime: UVR2G100MHD operates -40°C ~ 85°C with 2000 Hrs @ 85°C lifetime, while UAQ2G100MHD operates -40°C ~ 105°C with 2000 Hrs @ 105°C lifetime. UAQ2G100MHD is the upgraded alternative for higher temperature applications.

Q: Why does SK100M400ST have different case dimensions? A: SK100M400ST is manufactured by Cornell Dubilier Electronics and follows different dimensional standards. The case diameter is 0.512" (13.00 mm) versus 0.492" (12.50 mm) for the original, and height is 0.906" (23.00 mm) versus 0.866" (22.00 mm). This part is suitable only if PCB layout and mechanical clearance accommodate the larger footprint.

Q: Are all substitute parts RoHS compliant? A: Most substitute parts are ROHS3 compliant. The original UVR2G100MHA is RoHS non-compliant. UVR2G100MHD, UAQ2G100MHD, 400PX10MEFC12.5X20, and all Vishay parts (MAL series) are ROHS3 compliant. SK100M400ST is also ROHS3 compliant. RoHS compliance status should be verified against your application requirements.

Q: Which substitute offers the longest lifetime rating? A: MAL215257109E3 and MAL215267109E3 both offer 3000 Hrs @ 105°C, the longest lifetime among all listed substitutes. These Vishay parts also carry AEC-Q200 automotive qualification and 450 V rating.

Q: Can I use these capacitors interchangeably on the same PCB? A: Interchangeability depends on PCB layout. All substitutes except SK100M400ST share identical lead spacing (0.197", 5.00 mm), case diameter (0.492", 12.50 mm), and height (0.866", 22.00 mm), making them mechanically interchangeable. SK100M400ST requires PCB modification due to larger case dimensions. Electrical performance is equivalent across all listed parts for the specified application parameters.
