Substitute Part Grouping Explanation

Substitution of the 556152M050FR2 is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Capacitance value: 1500 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package / Case: Axial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -40°C to 105°C minimum (equal or wider range acceptable)

Secondary Compatibility Parameters:

• Voltage - Rated: 50 V minimum (equal or higher voltage rating acceptable)
• ESR: Lower or equal values preferred for performance optimization
• Ripple Current: Equal or higher values acceptable
• Lifetime @ Temperature: Equal or higher values acceptable

The substitute part MAL213818152E3 from Vishay Beyschlag/Draloric/BC Components meets all primary substitution criteria with identical capacitance, tolerance, polarization, package type, and mounting configuration. The substitute provides enhanced electrical performance through higher voltage rating (63 V vs. 50 V), lower ESR (100 mOhm vs. 180 mOhm), and extended lifetime (10000 Hrs vs. 4000 Hrs at 105°C).

Engineering Selection Recommendations

Primary Recommendation: MAL213818152E3

The Vishay Beyschlag/Draloric/BC Components MAL213818152E3 is the qualified substitute for the obsolete 556152M050FR2. Selection is based on the following engineering factors:

Electrical Compatibility: All critical electrical parameters align with or exceed the original specification. The 1500 µF capacitance and ±20% tolerance are exact matches. The 63 V voltage rating provides margin above the 50 V requirement, enhancing circuit reliability. The reduced ESR (100 mOhm vs. 180 mOhm) improves transient response and reduces heat generation. Higher ripple current ratings at both low and high frequencies support equivalent or enhanced circuit performance.

Mechanical Compatibility: Both components utilize identical axial, can package configuration with through-hole mounting. Physical dimensions differ (MAL213818152E3 is larger in diameter but shorter in length), requiring verification of PCB layout and mechanical clearance in the target application.

Compliance and Supply Status: The substitute part is ROHS3 compliant, addressing modern regulatory requirements, whereas the original is RoHS non-compliant. The substitute maintains active product status with confirmed inventory availability (912 pcs), ensuring reliable supply for production and field service applications.

Temperature and Lifetime Performance: Operating temperature range is identical (-40°C to 105°C). The substitute provides extended lifetime (10000 Hrs @ 105°C vs. 4000 Hrs), reducing field failure risk in long-term applications.

Frequently Asked Questions (FAQ)

Q1: Can MAL213818152E3 be used as a direct replacement for 556152M050FR2 in all applications?

A: MAL213818152E3 is electrically compatible as a substitute. However, physical dimensions differ: the substitute is 0.827" diameter × 1.496" length versus the original 0.630" diameter × 1.752" length. PCB layout and mechanical clearance must be verified before implementation. If space constraints are critical, physical fit assessment is required.

Q2: What are the key electrical advantages of the substitute part?

A: The MAL213818152E3 provides three measurable electrical improvements: (1) higher voltage rating (63 V vs. 50 V) for increased safety margin, (2) lower ESR (100 mOhm vs. 180 mOhm) for reduced ripple voltage and heat dissipation, and (3) extended lifetime (10000 Hrs vs. 4000 Hrs at 105°C) for improved reliability.

Q3: Are there any compliance differences between the original and substitute?

A: Yes. The original 556152M050FR2 is RoHS non-compliant, while the substitute MAL213818152E3 is ROHS3 compliant. This is advantageous for new designs and systems requiring modern regulatory compliance. Both parts are REACH unaffected and carry EAR99 ECCN classification.

Q4: What is the impact of different physical dimensions on circuit design?

A: The substitute is larger in diameter (0.827" vs. 0.630") but shorter in length (1.496" vs. 1.752"). This may affect PCB routing, component spacing, and mechanical assembly. Verify that the substitute fits within available board space and does not interfere with adjacent components or mechanical structures.

Q5: Is the substitute suitable for automotive applications?

A: The substitute MAL213818152E3 is specified for automotive applications. The original 556152M050FR2 is designated for general-purpose use. If the original application was non-automotive, the substitute's automotive-grade specification provides additional quality assurance without introducing incompatibility.

Q6: How do ripple current ratings compare?

A: At 120 Hz (low frequency), ripple currents are equivalent (1.67 A vs. 1.68 A). At 10 kHz (high frequency), the substitute provides higher capacity (2.352 A vs. 1.92 A), supporting applications with elevated high-frequency ripple current demands.

Q7: What is the lead spacing for these components?

A: Lead spacing information is not provided in the technical specifications for either component. Physical measurement or direct contact with manufacturers is required if lead spacing is a critical design parameter.
