MALSECA00AG322HARK Equivalent & Substitute Parts

Part Overview

The MALSECA00AG322HARK is a 220 µF, 50 V aluminum electrolytic capacitor in radial, can-style surface mount packaging manufactured by Vishay Beyschlag/Draloric/BC Components. This component belongs to the ECA series and is classified as obsolete. The part is designed for general-purpose applications requiring stable capacitance and moderate ripple current handling at low frequencies.

Due to its obsolete status, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure supply chain availability for new production runs or field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MALSECA00AG322HARK is determined by the following mandatory parameters:

• Capacitance value: 220 µF (exact match required)
• Voltage rating: 50 V (minimum, equal or higher acceptable)
• Tolerance: ±20% (matching tolerance class)
• Package type: Radial, Can - SMD (physical form factor)
• Mounting type: Surface Mount (PCB assembly compatibility)
• Polarization: Polar (electrolytic capacitor type)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

The two substitute parts listed below meet all mandatory substitution criteria. They differ in ESR characteristics, temperature lifetime ratings, and maximum operating temperature, which are secondary parameters that may influence performance in specific thermal or ripple current environments but do not prevent functional substitution.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are classified as active products with current manufacturing status, ensuring long-term supply availability compared to the obsolete MALSECA00AG322HARK.

227SML050M (Direct Substitute): This part provides electrical and thermal characteristics closely aligned with the original component. It maintains the same 2000-hour lifetime rating at 85°C and identical ripple current specification at 120 Hz. The slightly higher ESR (904.3 mOhm vs. 720 mOhm) represents a 25.6% increase but remains within acceptable tolerance for general-purpose applications. The maximum height of 11.00 mm exceeds the original 10.50 mm specification by 0.50 mm, requiring verification of PCB clearance in space-constrained designs. Surface mount land size differs (10.00 mm x 10.00 mm vs. 10.30 mm x 10.30 mm), necessitating PCB layout review.

227SVH050MGE (Upgrade Substitute): This part offers enhanced thermal performance with a maximum operating temperature of 105°C and lifetime rating of 2000 hours at 105°C, compared to 85°C for the original. Higher ripple current capability (375 mA @ 120 Hz vs. 320 mA) provides additional margin in high-ripple environments. The increased ESR (1.06 Ohm) may introduce slightly higher power dissipation in applications with continuous ripple current. Physical height (10.60 mm) and surface mount land size (10.30 mm x 10.30 mm) are compatible with the original design envelope. ROHS3 compliance and MSL rating 1 match the original specifications.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring regulatory and manufacturing process compatibility.

Frequently Asked Questions (FAQ)

Q: Can 227SML050M be used as a direct drop-in replacement for MALSECA00AG322HARK?

A: Electrical substitution is valid based on matching capacitance, voltage rating, tolerance, and package type. However, the increased height (11.00 mm vs. 10.50 mm) and different surface mount land size (10.00 mm x 10.00 mm vs. 10.30 mm x 10.30 mm) require PCB layout verification before implementation.

Q: What is the significance of the ESR difference between the three parts?

A: ESR (Equivalent Series Resistance) affects power dissipation and ripple current handling. The original MALSECA00AG322HARK has the lowest ESR at 720 mOhm. The 227SML050M increases ESR to 904.3 mOhm (25.6% higher), while the 227SVH050MGE reaches 1.06 Ohm (47.2% higher). In applications with high ripple current or thermal constraints, higher ESR may increase component temperature rise. For general-purpose applications, both substitutes remain acceptable.

Q: Is the 227SVH050MGE suitable for high-temperature environments?

A: Yes. The 227SVH050MGE supports operating temperatures up to 105°C with a 2000-hour lifetime rating at that temperature, compared to the original part's 85°C maximum. This makes it suitable for applications requiring extended thermal performance. However, the higher ESR may generate additional heat under ripple current conditions.

Q: Are there PCB layout considerations when switching from MALSECA00AG322HARK to 227SML050M?

A: Yes. The surface mount land size differs: the original uses 10.30 mm x 10.30 mm pads, while the 227SML050M requires 10.00 mm x 10.00 mm pads. Additionally, the 227SML050M is 0.50 mm taller (11.00 mm vs. 10.50 mm), which may affect clearance with adjacent components or solder mask coverage. PCB artwork must be updated accordingly.

Q: Do all three parts meet current regulatory requirements?

A: Yes. All three parts are ROHS3 compliant and carry MSL rating 1 (unlimited moisture sensitivity level), meeting current manufacturing and environmental standards.

Q: Which substitute should be selected for a new design?

A: Selection depends on application requirements. For general-purpose applications with standard thermal conditions, either substitute is acceptable. For designs requiring higher ripple current capability or extended temperature operation, the 227SVH050MGE is preferred. For designs with strict height constraints, the 227SVH050MGE (10.60 mm) is preferable to the 227SML050M (11.00 mm).
