106SVF050MST Equivalent & Substitute Parts

Part Overview

The 106SVF050MST is a 10 µF, 50 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the SVF series. This radial, through-hole component is designed for bypass and decoupling applications with a rated lifetime of 1000 hours at 85°C. The part is currently in active production status with 935 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life, experiences supply constraints, or when design flexibility requires alternative sourcing options. The 106SVF050MST has documented equivalent alternatives that maintain functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 106SVF050MST is determined by strict alignment of the following critical parameters:

Electrical Parameters:

• Capacitance: 10 µF (exact match required)
• Voltage Rating: 50 V (exact match required)
• Tolerance: ±20% (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Lifetime: 1000 Hrs @ 85°C (exact match required)
• Polarization: Polar (exact match required)

Mechanical Parameters:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 0.098" (2.50mm) (exact match required)
• Size / Dimension: 0.248" Dia (6.30mm) (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)

The substitute part 50MS510MEFC6.3X5 from Rubycon meets all critical electrical and mechanical parameters. Variations in non-critical specifications such as ESR values and ripple current ratings do not disqualify substitution when the core parameters align.

Parameter Comparison

Engineering Selection Recommendations

The 50MS510MEFC6.3X5 from Rubycon qualifies as a direct substitute for the 106SVF050MST based on matching electrical specifications, mechanical dimensions, and regulatory compliance.

Product Status Consideration: The 106SVF050MST maintains active production status, while the 50MS510MEFC6.3X5 is classified as obsolete. Selection of the substitute should be driven by supply availability and procurement requirements rather than performance differences.

Compliance Verification: Both parts are ROHS3 compliant and carry the same ECCN (EAR99) and HTSUS (8532.22.0020) classifications, confirming regulatory equivalence for export and procurement purposes.

Physical Compatibility: The height variation between parts (0.236" versus 0.256" seated height) represents a 0.020" (0.50mm) difference. This variation falls within typical PCB layout tolerances for through-hole radial capacitors and does not constitute a substitution barrier for standard applications.

Electrical Performance: Both parts support identical bypass and decoupling applications within the specified voltage and temperature ranges. The ripple current specifications are measured under different frequency conditions; direct comparison requires application-specific analysis of actual operating frequencies.

Frequently Asked Questions (FAQ)

Q: Can the 50MS510MEFC6.3X5 be used as a direct replacement for the 106SVF050MST on existing PCBs?

A: Yes. Both parts share identical lead spacing (0.098" / 2.50mm), diameter (0.248" / 6.30mm), and mounting type (through-hole radial). The 0.020" height difference does not affect PCB compatibility for standard applications.

Q: What is the significance of the product status difference (Active vs. Obsolete)?

A: Product status indicates manufacturing availability. The 106SVF050MST is currently in production; the 50MS510MEFC6.3X5 is no longer manufactured. Selection should prioritize the active part when supply is available. The obsolete part serves as a substitute only when the primary part is unavailable.

Q: Are the ripple current ratings directly comparable between these parts?

A: No. The 106SVF050MST specifies ripple current at 100 kHz (56.1 mA), while the 50MS510MEFC6.3X5 specifies ripple current at 10 kHz (46.5 mA). These measurements occur under different frequency conditions. Application-specific ripple current requirements must be evaluated against the actual operating frequency of the circuit.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications. They are equivalent for export control and procurement compliance purposes.

Q: What does the ±20% tolerance mean for capacitance?

A: The capacitance value may vary between 8 µF and 12 µF across the production range. Both the 106SVF050MST and 50MS510MEFC6.3X5 share this tolerance specification, ensuring equivalent performance in applications where this tolerance band is acceptable.

Q: Can these parts be used interchangeably in high-frequency applications?

A: Interchangeability in high-frequency applications depends on circuit-specific requirements. The ESR (Equivalent Series Resistance) value of 19.894 Ohm is specified only for the 106SVF050MST. The 50MS510MEFC6.3X5 does not provide ESR data. Applications sensitive to ESR performance require verification of the substitute part's ESR characteristics before deployment.
