Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MALREKB05JS322M00K are classified into three categories based on electrical and mechanical compatibility:

Direct Manufacturer Equivalents maintain identical electrical specifications (220 µF, 160 V, ±20% tolerance) and mechanical dimensions (16.00 mm diameter, 7.50 mm lead spacing, through-hole radial package). These parts are interchangeable without circuit modification.

Upgrade Parts exceed the original specifications in voltage rating or lifetime performance while maintaining the same capacitance, tolerance, mechanical footprint, and lead spacing. These parts provide enhanced reliability and are backward-compatible with the original design.

Parametric Equivalents match the core electrical parameters (220 µF, 160 V, ±20% tolerance) and mechanical form factor but may differ in ESR characteristics or ripple current ratings. These parts are suitable for applications where the specific performance metrics of the original part are not critical constraints.

Substitution eligibility is determined by:

• Capacitance value (220 µF)
• Voltage rating (160 V minimum)
• Tolerance (±20%)
• Lead spacing (0.295" / 7.50 mm)
• Case diameter (0.630" / 16.00 mm)
• Mounting type (Through Hole, Radial)
• Package type (Radial, Can)

Engineering Selection Recommendations

For Direct Replacement: Select B43851F1227M000 (EPCOS - TDK), EKMG161ELL221MLN3S (Chemi-Con), EKMQ161ELL221MLN3S (Chemi-Con), or 160PX220MEFC16X31.5 (Rubycon). These parts maintain 160 V rating and identical mechanical dimensions. All are active products with ROHS3 compliance. B43851F1227M000 offers extended lifetime (3000 Hrs vs. 2000 Hrs) at the same voltage rating.

For Enhanced Reliability: Select EKXJ221ELL221MLN3S (Chemi-Con, 220 V, 12000 Hrs) or UCY2D221MHD (Nichicon, 200 V, 12000 Hrs). Both provide significantly extended operational lifetime and higher voltage ratings while maintaining identical mechanical form factor and lead spacing. These upgrades are suitable for applications requiring improved long-term stability and thermal performance.

Compliance Considerations: All substitute parts are ROHS3 compliant. UCY2D221MHD carries REACH Affected status, while all other substitutes are REACH Unaffected. Verify REACH compliance requirements for your specific application before selection.

Frequently Asked Questions (FAQ)

Q: Can I use a 200 V or 220 V rated capacitor in place of the 160 V original?

A: Yes. Higher voltage-rated capacitors are backward-compatible with lower voltage applications. UCY2D221MHD (200 V) and EKXJ221ELL221MLN3S (220 V) can replace the 160 V MALREKB05JS322M00K without circuit modification. The capacitor will operate safely at voltages below its rating.

Q: What is the difference between direct equivalents and upgrade parts?

A: Direct equivalents (B43851F1227M000, EKMG161ELL221MLN3S, EKMQ161ELL221MLN3S, 160PX220MEFC16X31.5) maintain the original 160 V specification. Upgrade parts (EKXJ221ELL221MLN3S, UCY2D221MHD) provide higher voltage ratings and extended lifetime (12000 Hrs vs. 2000 Hrs), offering improved reliability for demanding applications.

Q: Are all substitute parts mechanically interchangeable?

A: Yes. All substitute parts share identical lead spacing (0.295" / 7.50 mm), case diameter (0.630" / 16.00 mm), and through-hole radial mounting type. Minor height variations (1.299" vs. 1.319") do not affect PCB layout compatibility for standard through-hole designs.

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

A: EKXJ221ELL221MLN3S and UCY2D221MHD both provide 12000-hour lifetime at 105°C, compared to 2000-3000 hours for other options. EKXJ221ELL221MLN3S includes AEC-Q200 automotive qualification, while UCY2D221MHD is rated for general-purpose applications.

Q: Does ESR matter when selecting a substitute?

A: ESR is relevant for ripple current handling and thermal performance. The original part specifies 900 mOhm @ 120 Hz. Substitute parts with unspecified ESR are suitable for general-purpose applications where the original ESR specification was not a critical design constraint.

Q: What is the inventory status of substitute parts?

A: All substitute parts are in active production with confirmed stock availability: B43851F1227M000 (1020 Pcs), EKMG161ELL221MLN3S (1214 Pcs), EKMQ161ELL221MLN3S (1116 Pcs), EKXJ221ELL221MLN3S (909 Pcs), UCY2D221MHD (3400 Pcs), and 160PX220MEFC16X31.5 (975 Pcs).
