Substitute Part Grouping Explanation

Substitution for the MALREKB00DC322HG0K is determined by strict equivalence across the following parameters:

Capacitance: 220 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: 50 V (exact match required)
Lifetime: 2000 Hrs @ 105°C (exact match required)
Lead Spacing: 0.197" (5.00mm) (exact match required)
Size / Dimension: 0.394" Dia (10.00mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)
Polarization: Polar (exact match required)

All substitute parts listed below meet these criteria and are therefore electrically and mechanically interchangeable with the original part.

Engineering Selection Recommendations

For new designs and ongoing production, MAL214851221E3, 50PX220MEFC10X12.5, EEU-HD1H221, and EKMQ500ELL221MJC5S are preferred substitutes, as all are classified as Active products with current manufacturing status and full ROHS3 compliance.

MAL214851221E3 is the manufacturer-recommended substitute from Vishay Beyschlag/Draloric/BC Components, maintaining continuity within the same manufacturer ecosystem. This part operates across a narrower low-temperature range (-40°C minimum) compared to the original part (-55°C minimum), which is acceptable for most general-purpose applications.

50PX220MEFC10X12.5 from Rubycon and EKMQ500ELL221MJC5S from Chemi-Con both maintain the full operating temperature range of -55°C to 105°C and are suitable for applications requiring extended low-temperature performance.

EEU-HD1H221 from Panasonic Electronic Components is an active product with full temperature range coverage and represents a cross-manufacturer alternative with established supply availability.

UKA1H221MPD from Nichicon is classified as Not For New Designs and should be used only for legacy system maintenance or repair applications where original part compatibility is required.

Frequently Asked Questions (FAQ)

Q: Can I use MAL214851221E3 as a direct replacement for MALREKB00DC322HG0K?

A: Yes. Both parts share identical capacitance (220 µF), tolerance (±20%), voltage rating (50 V), lifetime (2000 Hrs @ 105°C), lead spacing (5.00mm), and physical dimensions (10.00mm diameter). The operating temperature range of MAL214851221E3 is -40°C to 105°C, which is narrower at the low end compared to the original part's -55°C to 105°C. This difference is acceptable for general-purpose applications operating within standard industrial temperature ranges.

Q: What is the difference between Active and Obsolete product status?

A: Obsolete parts are no longer manufactured and have limited inventory availability. Active parts are in current production with established supply chains. The MALREKB00DC322HG0K is obsolete, making substitution with active alternatives necessary for sustained production.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the compliance status of the original part.

Q: Does the height difference between substitute parts affect compatibility?

A: Height variations among substitute parts (ranging from 14.60mm to 14.50mm) are within acceptable mechanical tolerances for through-hole radial can packages. PCB layout and clearance requirements should be verified during design review, but these differences do not prevent functional substitution.

Q: Which substitute part has the highest ripple current rating?

A: The original MALREKB00DC322HG0K specifies 376 mA @ 120 Hz. Among substitutes, 50PX220MEFC10X12.5 provides 360 mA @ 120 Hz, which is the closest match. EEU-HD1H221 and EKMQ500ELL221MJC5S both specify 300 mA @ 120 Hz. Selection should be based on actual ripple current requirements in the application circuit.

Q: Can I use UKA1H221MPD for new designs?

A: No. UKA1H221MPD is classified as Not For New Designs. This designation indicates the manufacturer recommends against using this part in new product development. It should be reserved for maintenance and repair of existing systems where original part compatibility is required.
