UVR2F470MHA Equivalent & Substitute Parts

Part Overview

The UVR2F470MHA is a 47 µF, 315 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 The UVR series has been superseded by more advanced alternatives with improved performance characteristics, including higher voltage ratings, extended operating temperature ranges, and longer operational lifetimes. Identifying suitable substitute parts is essential for maintaining design continuity and ensuring long-term component availability.

Substitute Part Grouping Explanation

Substitution for the UVR2F470MHA is determined by the following critical parameters: capacitance value (47 µF), polarization (polar), package type (radial, can), lead spacing (7.50 mm), and physical dimensions (0.630" diameter, maximum height 1.063"). The voltage rating may be equal to or higher than 315 V, as higher-rated capacitors are backward compatible in lower-voltage applications. Operating temperature range and lifetime specifications may be improved without affecting functional compatibility.

Substitute parts are grouped into two categories:

Direct Substitutes (Same Voltage Rating): Parts maintaining 315 V rating with identical or improved performance metrics.

Upgraded Substitutes (Higher Voltage Rating): Parts rated at 350 V, 400 V, or 450 V, offering enhanced reliability and extended operational margins. These are suitable for direct replacement when circuit design permits higher voltage tolerance.

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Characteristics):

UVR2F470MHD is the closest direct substitute, maintaining identical 315 V rating and 2000 Hrs @ 85°C lifetime. This part is ROHS3 compliant and available in bulk packaging, making it suitable for immediate substitution in existing designs. However, it is classified as "Not For New Designs," indicating limited long-term availability.

For New Design Implementation:

EKMG351ELL470ML25S or EKMQ351ELL470ML25S (350 V rating) provide the minimum voltage upgrade while maintaining compact dimensions. Both are ROHS3 compliant and active products with extended operating temperature range (-40°C ~ 105°C).

For applications requiring maximum reliability and extended operational life, UCS2G470MHD (Nichicon, 400 V, 10000 Hrs @ 105°C) or 450BXW47MEFR16X25 (Rubycon, 450 V, 12000 Hrs @ 105°C) are recommended. These parts offer significantly extended lifetime ratings and higher voltage margins.

EGXF401ELL470ML25S (Chemi-Con, 400 V, 3000 Hrs @ 125°C) is suitable for automotive applications requiring AEC-Q200 certification and extended temperature operation to 125°C.

Compliance Considerations:

All recommended substitutes are ROHS3 compliant or RoHS compliant, addressing the non-compliance status of the original UVR2F470MHA. Selection should prioritize active product status to ensure long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a direct replacement?

A: Yes. A capacitor rated at 350 V, 400 V, or 450 V is electrically compatible in an application designed for 315 V operation. The higher voltage rating provides additional safety margin and does not affect circuit functionality. Physical dimensions and lead spacing must remain identical.

Q: What is the difference between UVR2F470MHD and UVR2F470MHA?

A: Both parts are identical in electrical specifications (47 µF, 315 V, ±20%, 2000 Hrs @ 85°C). The primary difference is RoHS compliance: UVR2F470MHA is RoHS non-compliant, while UVR2F470MHD is ROHS3 compliant. UVR2F470MHD is classified as "Not For New Designs," indicating limited future availability.

Q: Why should I consider UCS2G470MHD over UAS2G470MHD?

A: Both parts are 47 µF, 400 V, ROHS3 compliant Nichicon products. UCS2G470MHD offers 10000 Hrs @ 105°C lifetime compared to 2000 Hrs @ 105°C for UAS2G470MHD, providing five times longer operational life. UCS2G470MHD also supports higher ripple current (590 mA @ 120 Hz vs. 290 mA @ 120 Hz), making it suitable for demanding applications.

Q: Are there dimensional differences between substitute parts?

A: Most substitutes maintain the same 0.630" diameter and 7.50 mm lead spacing. However, height varies slightly: UVR2F470MHA and most Rubycon parts are 1.063" maximum height, while Chemi-Con and some Nichicon parts are 1.043" maximum height. This 0.020" difference is typically accommodated in standard PCB layouts.

Q: Which substitute offers the best temperature performance?

A: EGXF401ELL470ML25S (Chemi-Con) supports operation to 125°C with 3000 Hrs lifetime at that temperature, the highest operating temperature among all substitutes. This part is suitable for high-temperature environments and automotive applications requiring AEC-Q200 certification.

Q: What is the significance of "Active" product status?

A: "Active" status indicates the manufacturer actively produces and supports the part, ensuring long-term availability and supply chain stability. Parts classified as "Not For New Designs" or "Obsolete" have limited production and may become unavailable, making them unsuitable for new product development.
