Substitute Part Grouping Explanation

Substitution of the MALSECA00AG310HARK is determined by strict equivalence in the following parameters:

Capacitance value: 100 µF (exact match required)
Voltage rating: 50 V (exact match required)
Tolerance: ±20% (exact match required)
Package type: Radial, Can - SMD (exact match required)
Mounting type: Surface Mount (exact match required)
Physical dimensions: 0.394" diameter × 0.413" height maximum (within tolerance)
Polarization: Polar (exact match required)
RoHS compliance: ROHS3 Compliant (required for regulatory compliance)
MSL rating: 1 (Unlimited) (required for storage and handling)

All substitute parts listed meet these core electrical and mechanical requirements. Variations in ESR, ripple current ratings, lifetime specifications, and operating temperature ranges represent performance enhancements or different application suitability but do not prevent functional substitution.

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance and MSL rating 1, ensuring regulatory compliance and long-term availability. Selection among substitutes should be based on application-specific requirements:

MAL215371101E3 offers improved ESR performance (300 mOhm @ 100 kHz) and extended lifetime (3000 Hrs @ 105°C) within the same Vishay manufacturer family, providing a direct upgrade path for designs requiring enhanced performance margins.

107SML050MD10 from Cornell Dubilier maintains electrical characteristics closely aligned with the original part, with identical ESR and lifetime specifications at 85°C, suitable for direct replacement in existing designs without thermal stress.

107SVL050MGW and ATB107M050 provide extended operating temperature range (-55°C ~ 105°C) and significantly extended lifetime (5000 Hrs @ 105°C), appropriate for applications requiring enhanced reliability or operation in elevated temperature environments.

RVJ-50V101MH10U-R from Elna America offers high ripple current capability (324 mA @ 120 Hz, 486 mA @ 100 kHz) and extended operating temperature range, suitable for high-current bypass and decoupling applications.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for MALSECA00AG310HARK?

A: Yes. All listed parts meet the core electrical and mechanical requirements: 100 µF capacitance, 50 V voltage rating, ±20% tolerance, radial can SMD package, and surface mount configuration. Physical dimensions are within acceptable tolerance for PCB land patterns.

Q: What is the difference between the substitute parts?

A: Substitute parts differ in ESR characteristics, lifetime ratings at elevated temperatures, maximum operating temperature range, and ripple current capacity. These variations represent performance enhancements but do not affect basic functional compatibility.

Q: Does the height difference between 0.413" and 0.417" affect PCB compatibility?

A: The 0.004" (0.10 mm) height difference is within standard PCB assembly tolerances and does not require design modification. Verify clearance in your specific application if height-constrained.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and carry MSL rating 1 (Unlimited), meeting current regulatory requirements and storage standards.

Q: Which substitute part should I choose for a high-temperature application?

A: Parts with extended operating temperature range (-55°C ~ 105°C) and higher lifetime ratings at 105°C are MAL215371101E3, 107SVL050MGW, ATB107M050, and RVJ-50V101MH10U-R. Selection depends on specific ripple current and ESR requirements.
