Substitute Part Grouping Explanation

Substitution for the MALREKB00JS422H00K is determined by strict equivalence across the following parameters:

Capacitance: 2200 µF (exact match required)
Voltage Rating: 50 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can (exact match required)
Lead Spacing: 0.295" (7.50mm) (exact match required)
Case Diameter: 0.630" (16.00mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Polarization: Polar (exact match required)

All substitute parts listed meet these core electrical and mechanical parameters. Differences in lifetime ratings, ripple current specifications, and ESR values do not disqualify parts from substitution, as these represent performance enhancements or variations within the same functional category.

Engineering Selection Recommendations

All listed substitute parts are electrically and mechanically equivalent to the MALREKB00JS422H00K and are suitable for direct replacement in through-hole applications requiring 2200 µF, 50 V aluminum electrolytic capacitors.

MAL214851222E3 is the manufacturer-recommended substitute from Vishay Beyschlag/Draloric/BC Components, offering extended lifetime (3000 hours at 105°C) while maintaining ROHS3 compliance and active product status.

EKMQ500EC3222MLN3S and EKMQ500ELL222MLN3S are active Chemi-Con alternatives with identical electrical specifications and ROHS3 compliance. These parts feature slightly reduced seated height (1.299" versus 1.319") but maintain all critical mechanical parameters.

ECA-1HHG222, ECA-1HHG222C, and EEU-HD1H222 are active Panasonic alternatives with full ROHS3 compliance. ECA-1HHG222C carries AEC-Q200 automotive qualification. All three maintain the original seated height of 1.319" and are suitable for general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for MALREKB00JS422H00K?

A: Yes. All listed parts meet the core electrical and mechanical specifications: 2200 µF capacitance, 50 V voltage rating, ±20% tolerance, radial can package, 0.295" lead spacing, 0.630" case diameter, and through-hole mounting. Physical board layout compatibility is confirmed.

Q: What is the difference between the Vishay, Chemi-Con, and Panasonic alternatives?

A: All three manufacturers provide equivalent parts meeting the same electrical and mechanical parameters. Differences exist in lifetime ratings, ripple current specifications, and series designations. MAL214851222E3 offers extended 3000-hour lifetime. Chemi-Con parts feature slightly reduced height. Panasonic parts maintain original dimensions, with ECA-1HHG222C offering automotive-grade qualification.

Q: Does the height difference in Chemi-Con parts affect compatibility?

A: The Chemi-Con parts (EKMQ500EC3222MLN3S and EKMQ500ELL222MLN3S) have a maximum seated height of 1.299" compared to 1.319" for the original part. This 0.020" reduction does not affect through-hole mounting compatibility and may provide clearance benefits in space-constrained designs.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification, matching the original MALREKB00JS422H00K specification.

Q: Why is the original part marked as obsolete?

A: The MALREKB00JS422H00K from the EKB series is classified as obsolete. All active substitute parts provide equivalent or enhanced performance characteristics and are recommended for new designs and ongoing production requirements.

Q: Which substitute offers the best long-term reliability?

A: MAL214851222E3 provides extended lifetime rating of 3000 hours at 105°C, compared to 2000 hours for the original part and most alternatives. This represents a 50% increase in rated operational life under maximum temperature conditions.
