Key Parameters

Substitute Part Grouping Explanation

Substitution of the MALREKB00BA322DM0K is determined by strict equivalence in the following parameters: capacitance (220 µF), voltage rating (16 V minimum), tolerance (±20%), package type (radial, can), lead spacing (0.098" / 2.50 mm), case diameter (0.248" / 6.30 mm), mounting type (through hole), and polarization (polar). Height variation within 0.492" ± 0.008" is acceptable for mechanical fit. Lifetime at 105°C of 1000 hours or greater satisfies the thermal performance requirement. Operating temperature range must encompass -55°C to 105°C.

Substitute parts are categorized as follows:

Direct Equivalents maintain identical electrical and mechanical specifications with active product status from established manufacturers.

Upgrade Substitutes provide enhanced performance characteristics such as higher voltage rating (25 V) or extended lifetime (2000 hours), suitable for applications requiring improved reliability margins.

Parametric Equivalents meet all critical electrical and mechanical parameters with minor variations in ripple current or height within acceptable tolerances.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring direct replacement with active product status and identical specifications, select ECA-1CHG221 (Panasonic NHG-A series, bulk packaging) or EKMG160ELL221MF11D (Chemi-Con KMG series). Both parts maintain 220 µF capacitance, 16 V rating, ±20% tolerance, and 1000-hour lifetime at 105°C with through-hole radial can packaging.

For applications where packaging format is critical, ECA-1CHG221I provides identical electrical specifications in cut tape format for automated assembly processes.

For applications requiring enhanced reliability margins, EKMQ250ELL221MF11D (Chemi-Con KMQ series) offers 25 V rating while maintaining 220 µF capacitance and identical physical dimensions, providing voltage derating capability.

For applications with extended thermal cycling requirements, UKA1C221MED (Nichicon UKA series) provides 2000-hour lifetime at 105°C, though this part is obsolete and availability is limited.

All recommended substitutes are ROHS3 compliant and REACH unaffected, matching the environmental compliance profile of the original part.

Frequently Asked Questions (FAQ)

Q: Can ECA-1CHG221 directly replace MALREKB00BA322DM0K in existing PCB designs?

A: Yes. Both parts share identical capacitance (220 µF), voltage rating (16 V), tolerance (±20%), lead spacing (0.098" / 2.50 mm), case diameter (0.248" / 6.30 mm), and through-hole radial can package. The height difference of 0.012" (0.480" vs 0.492") is within acceptable mechanical tolerance for standard PCB layouts.

Q: What is the difference between ECA-1CHG221 and ECA-1CHG221I?

A: Both parts are electrically and mechanically identical. The primary difference is packaging format: ECA-1CHG221 is supplied in bulk, while ECA-1CHG221I is supplied in cut tape format. Selection depends on assembly process requirements.

Q: Why is EKMQ250ELL221MF11D listed as an upgrade substitute?

A: EKMQ250ELL221MF11D maintains the same capacitance (220 µF), tolerance (±20%), physical dimensions, and lead spacing as the original part, but provides a higher voltage rating of 25 V instead of 16 V. This allows operation in circuits with higher voltage transients or provides additional safety margin in existing 16 V applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the environmental compliance requirements of the original MALREKB00BA322DM0K.

Q: What is the significance of ripple current differences among substitute parts?

A: Ripple current ratings indicate the maximum AC current the capacitor can handle at specified frequency without exceeding temperature limits. Differences among substitutes (180–220 mA @ 120 Hz) reflect design variations between manufacturers. Selection should ensure the application's ripple current requirement does not exceed the substitute part's rating.

Q: Can obsolete substitute parts like UKA1C221MED or UVY1C221MED be used?

A: Obsolete parts may be used if inventory is available and application requirements permit. However, for new designs or long-term production, active-status parts such as ECA-1CHG221, EKMG160ELL221MF11D, or 16PX220MEFC6.3X11 are recommended to ensure supply chain continuity.
