Substitute Part Grouping Explanation

Substitution for the UVR2G470MHA is determined by strict equivalence across the following critical parameters: capacitance (47 µF), voltage rating (400 V), tolerance (±20%), polarization (polar), package type (radial, can), and mounting method (through hole). Lead spacing and physical dimensions must remain compatible with existing PCB layouts.

Substitute parts are grouped into three categories:

Direct Manufacturer Equivalent: UVR2G470MHD maintains identical electrical specifications and physical dimensions as the original part, differing only in product status and RoHS compliance level.

Upgrade Equivalent: UAQ2G470MHD and MAL214267479E3 meet or exceed the core electrical parameters while offering enhanced operational characteristics such as higher temperature ratings or extended lifetime ratings.

Parametric Equivalent: UVR2G470MHD1AA provides identical electrical and mechanical specifications with active product status.

Similar Alternative: SK470M400ST matches the primary electrical specifications and physical form factor while originating from an alternative manufacturer.

Engineering Selection Recommendations

For applications requiring direct electrical and mechanical compatibility with existing designs, UVR2G470MHD or UVR2G470MHD1AA provide equivalent performance. Both parts maintain the original 47 µF capacitance, 400 V voltage rating, and thermal specifications while offering active or improved product status compared to the obsolete UVR2G470MHA.

For new designs or applications where enhanced reliability is required, UAQ2G470MHD is recommended. This part extends the operating temperature range to 105°C and maintains a 2000-hour lifetime at that elevated temperature, providing superior thermal margin. The part carries active product status and ROHS3 compliance.

MAL214267479E3 offers the highest voltage rating at 450 V with extended lifetime of 2500 hours at 105°C, suitable for applications requiring additional voltage headroom or enhanced long-term reliability. This part is manufactured by Vishay Beyschlag/Draloric/BC Components and carries active product status with ROHS3 compliance.

SK470M400ST from Cornell Dubilier Electronics provides an alternative from a different manufacturer with matching core specifications. This part is suitable for applications where multi-source qualification is required, though ripple current ratings are lower than the Nichicon equivalents.

Frequently Asked Questions (FAQ)

Q: Can UVR2G470MHD be used as a direct replacement for UVR2G470MHA?

A: Yes. UVR2G470MHD maintains identical capacitance (47 µF), voltage rating (400 V), tolerance (±20%), operating temperature range (-40°C to 85°C), ripple current specifications, lead spacing (7.50 mm), and package type (radial, can). Physical dimensions and mounting compatibility are preserved.

Q: What is the difference between UVR2G470MHD and UAQ2G470MHD?

A: Both parts share the same capacitance, voltage rating, and tolerance. UAQ2G470MHD extends the operating temperature range to 105°C and maintains its 2000-hour lifetime at that temperature, compared to 85°C for UVR2G470MHD. UAQ2G470MHD ripple current ratings are lower (280 mA @ 120 Hz versus 370 mA). UAQ2G470MHD carries active product status.

Q: Is MAL214267479E3 compatible with the original UVR2G470MHA footprint?

A: Yes. MAL214267479E3 maintains the same lead spacing (7.50 mm), package type (radial, can), and mounting method (through hole). Physical dimensions are nearly identical (height 37.00 mm versus 37.50 mm). The part is manufactured by Vishay Beyschlag/Draloric/BC Components rather than Nichicon.

Q: Why does SK470M400ST have lower ripple current ratings?

A: SK470M400ST from Cornell Dubilier Electronics is rated for 160 mA ripple current at 120 Hz, compared to 370 mA for the Nichicon UVR2G470MHA. This reflects different design characteristics between manufacturers. Applications requiring the full 370 mA ripple current capacity should use Nichicon equivalents.

Q: Can I use UAQ2G470MHD in an application designed for UVR2G470MHA?

A: Yes. UAQ2G470MHD meets all electrical specifications of UVR2G470MHA and provides enhanced temperature performance. The lower ripple current ratings (280 mA @ 120 Hz versus 370 mA) must be evaluated against application requirements. If the application requires the full 370 mA ripple current, UVR2G470MHD or UVR2G470MHD1AA are more appropriate.

Q: What is the significance of product status (Active, Not For New Designs, Obsolete)?

A: Product status indicates manufacturer support and availability. Obsolete parts (UVR2G470MHA) are no longer manufactured. "Not For New Designs" parts (UVR2G470MHD) remain available but are not recommended for new applications. Active parts (UAQ2G470MHD, UVR2G470MHD1AA, MAL214267479E3, SK470M400ST) are currently manufactured and supported for both existing and new designs.

Q: Are all substitute parts ROHS3 compliant?

A: UVR2G470MHD, UAQ2G470MHD, MAL214267479E3, and SK470M400ST are ROHS3 compliant. The original UVR2G470MHA is RoHS non-compliant. UVR2G470MHD1AA RoHS status is not specified in the provided data.
