Engineering Selection Recommendations

MAL215371228E3 (Vishay Beyschlag/Draloric/BC Components)

The MAL215371228E3 qualifies as an upgrade substitute for the 225SML050MD4. This part maintains all critical electrical and mechanical parameters while offering enhanced performance characteristics. The ESR is significantly reduced to 12 Ohm @ 100kHz compared to 90.429 Ohm @ 120Hz in the original part, resulting in improved high-frequency performance. The operating temperature range extends to -55°C to 105°C, and the lifetime rating extends to 2000 Hrs @ 105°C, providing superior thermal stability. Physical dimensions are compatible with identical land sizes and slightly reduced height (5.30mm vs 5.50mm). The part maintains ROHS3 compliance and MSL Level 1 rating. Product status is Active with substantial inventory availability (5781 Pcs). This substitute is suitable for applications requiring lower impedance characteristics and extended temperature performance.

UWJ1H2R2MCL1GB (Nichicon)

The UWJ1H2R2MCL1GB qualifies as a parametric equivalent substitute for the 225SML050MD4. This part matches all critical electrical and mechanical parameters including capacitance, voltage rating, tolerance, package type, and physical dimensions. Operating temperature range matches the original at -40°C to 85°C, and lifetime rating matches at 2000 Hrs @ 85°C. Ripple current ratings are comparable (13 mA @ 120 Hz and 19.5 mA @ 10 kHz). Physical dimensions are identical. However, this part carries Obsolete product status, indicating discontinued manufacturing. REACH status is listed as Affected, requiring compliance verification for regulated applications. Inventory availability is moderate (3761 Pcs). This substitute is suitable only for applications where original part specifications are strictly required and where product obsolescence does not present supply chain risk.

Frequently Asked Questions (FAQ)

Q: Can the MAL215371228E3 be used as a direct replacement for the 225SML050MD4?

A: Yes. The MAL215371228E3 satisfies all mandatory matching parameters: 2.2 µF capacitance, 50 V voltage rating, ±20% tolerance, polar polarization, radial can SMD package type, surface mount configuration, and identical physical dimensions and land sizes. The part is electrically and mechanically compatible with the original design.

Q: What is the primary advantage of the MAL215371228E3 over the original 225SML050MD4?

A: The MAL215371228E3 provides significantly lower ESR (12 Ohm @ 100kHz versus 90.429 Ohm @ 120Hz), extended operating temperature range (-55°C to 105°C versus -40°C to 85°C), and higher temperature lifetime rating (2000 Hrs @ 105°C versus 2000 Hrs @ 85°C). These characteristics result in improved high-frequency performance and thermal stability.

Q: Why is the UWJ1H2R2MCL1GB listed as Obsolete?

A: The UWJ1H2R2MCL1GB carries Obsolete product status, indicating that Nichicon has discontinued manufacturing this part. While inventory is currently available, future supply cannot be guaranteed. This status should be considered in long-term design planning and supply chain strategy.

Q: Are there any compliance differences between the substitute parts and the original?

A: All three parts maintain ROHS3 compliance and MSL Level 1 rating. The primary compliance difference is that the UWJ1H2R2MCL1GB carries REACH Affected status, while both the original 225SML050MD4 and the MAL215371228E3 carry REACH Unaffected status. Applications subject to REACH regulations should prioritize the MAL215371228E3 or confirm REACH compliance requirements with the UWJ1H2R2MCL1GB.

Q: Do the substitute parts require different PCB footprints?

A: No. All substitute parts maintain identical land sizes of 0.169" L × 0.169" W (4.30mm × 4.30mm), ensuring direct PCB footprint compatibility. The MAL215371228E3 has a slightly reduced height (5.30mm versus 5.50mm), which provides additional clearance margin but does not affect footprint compatibility.

Q: What packaging formats are available for these parts?

A: The original 225SML050MD4 is supplied in Bulk packaging. Both substitute parts, MAL215371228E3 and UWJ1H2R2MCL1GB, are supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations.

Q: How do the ripple current ratings compare?

A: The original 225SML050MD4 provides 15 mA @ 120 Hz and 22.5 mA @ 100 kHz. The MAL215371228E3 provides 10 mA @ 100 Hz. The UWJ1H2R2MCL1GB provides 13 mA @ 120 Hz and 19.5 mA @ 10 kHz. Applications with high ripple current requirements should evaluate specific frequency characteristics against circuit demands.

Q: Is ESR specification critical for my application?

A: ESR becomes critical in applications involving high-frequency switching, power supply filtering, or circuits sensitive to impedance characteristics. The MAL215371228E3 offers substantially lower ESR (12 Ohm @ 100kHz), making it preferable for such applications. The original 225SML050MD4 and UWJ1H2R2MCL1GB are suitable for general purpose applications where ESR is less critical.
