Engineering Selection Recommendations

Direct Equivalent (Same Electrical & Thermal Specifications):

UVR2C470MHD is the direct equivalent with identical electrical performance. It maintains 160 V rating, 47 µF capacitance, and 2000 hours lifetime at 85°C. The primary advantage is ROHS3 compliance. However, this part is classified as "Not For New Designs," indicating limited future availability.

Recommended Upgrade Path (Active Product Status):

For new designs and long-term production continuity, select from active parts:

UBT2C470MHD8 (Nichicon UBT series): Maintains 160 V rating with extended thermal capability (2000 Hrs @ 125°C, -40°C ~ 125°C). Active status ensures ongoing supply. Automotive-grade qualification provides additional reliability margin.
UAQ2D470MHD6 or UAS2D470MHD6 (200 V rating): Both offer 200 V rating with extended operating temperature to 105°C. Active status with ROHS3 compliance. Suitable for applications where voltage margin is acceptable.
UCS2D470MHD (200 V, 10000 Hrs @ 105°C): Extended lifetime (10000 hours) with 200 V rating. Active status. Recommended for applications requiring enhanced reliability and longer service intervals.
UCY2D470MHD3 (200 V, 12000 Hrs @ 105°C): Highest lifetime rating at 200 V (12000 hours @ 105°C). Active status. Optimal for critical applications demanding maximum operational life.
UCS2E470MHD or UCY2E470MHD3 (250 V rating): Highest voltage margin with extended lifetime. Active status. Suitable for applications with voltage stress concerns or future design margin requirements.

All recommended upgrades maintain identical mechanical compatibility (lead spacing, package type, mounting) and electrical parameters (47 µF, ±20% tolerance).

Frequently Asked Questions (FAQ)

Q: Can UVR2C470MHD directly replace UVR2C470MHA?

A: Yes. Both parts share identical electrical specifications (47 µF, 160 V, ±20%, 2000 Hrs @ 85°C) and mechanical dimensions. The primary difference is RoHS3 compliance in the MHD variant. However, MHD is classified "Not For New Designs," limiting long-term availability.

Q: What is the difference between 160 V and 200 V rated substitutes?

A: 200 V rated parts (UAQ2D470MHD6, UAS2D470MHD6, UCS2D470MHD, UCY2D470MHD3) provide higher voltage margin. They are electrically compatible in 160 V applications. Selection depends on circuit voltage stress and design margin requirements. All maintain identical capacitance (47 µF) and tolerance (±20%).

Q: Why do some substitutes have higher lifetime ratings (10000 or 12000 hours)?

A: Extended lifetime ratings (UCS and UCY series) indicate improved internal construction and materials. These parts maintain performance over longer operational periods at elevated temperatures. Selection depends on application duty cycle and required service life.

Q: Are all substitute parts mechanically compatible?

A: Yes. All listed substitutes maintain identical lead spacing (0.197" / 5.00 mm), package type (Radial, Can), and mounting type (Through Hole). Physical dimensions are within acceptable tolerance (0.492" Dia, height 0.846" to 0.866"). Direct PCB replacement is possible without layout modification.

Q: Which substitute is recommended for new designs?

A: UBT2C470MHD8 (automotive-grade, active status, extended temperature range) or UCY2D470MHD3 (highest lifetime, active status, 200 V rating) are preferred for new designs. Both offer active product status, ROHS3 compliance, and long-term supply assurance.

Q: What is the impact of RoHS compliance on substitution?

A: The original UVR2C470MHA is RoHS non-compliant. All recommended substitutes are ROHS3 compliant, meeting current environmental and regulatory requirements. This is mandatory for applications subject to RoHS directives.
