Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 6.3MS522MEFC4X5 are grouped based on the following criteria:

Direct Equivalents (Same Electrical & Mechanical Specifications):

• Capacitance: 22 µF
• Voltage Rating: 6.3 V
• Tolerance: ±20%
• Lifetime: 1000 Hrs @ 85°C
• Package: Radial, Can
• Lead Spacing: 0.059" (1.50mm)
• Size: 0.157" Dia (4.00mm)
• Mounting: Through Hole

Direct equivalent parts maintain identical electrical performance and physical form factor, ensuring drop-in compatibility.

Upgrade Parts (Enhanced Specifications):

• Voltage Rating: 10 V or 16 V (higher voltage rating with same capacitance and package)
• Lifetime: 2000 Hrs @ 85°C (extended lifetime with same voltage rating)
• Operating Temperature: Extended range (-55°C ~ 105°C)

Upgrade parts provide enhanced performance characteristics while maintaining mechanical compatibility and the same 22 µF capacitance value.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Specifications): ECE-A0JKS220 (Panasonic) and UML0J220MDD (Nichicon) are active production parts that provide direct electrical equivalence to the obsolete 6.3MS522MEFC4X5. Both maintain 22 µF capacitance, 6.3 V rating, ±20% tolerance, and 1000 hour lifetime at 85°C. Both are ROHS3 compliant. ECE-A0JKS220 has a reduced height of 0.197" (5.00mm) compared to the original 0.256" (6.50mm), while UML0J220MDD maintains a height of 0.236" (6.00mm), closer to the original specification.

For Enhanced Lifetime (Same Voltage Rating): UMR0J220MCD2 (Nichicon) provides the same 6.3 V rating and 22 µF capacitance as the original part but extends the lifetime to 2000 hours at 85°C. This part is suitable for applications requiring extended operational life while maintaining the original voltage specification.

For Higher Voltage Rating (Upgrade): ECE-A1AKA220 and ECE-A1CKA220 (Panasonic) offer 10 V and 16 V ratings respectively, both with 22 µF capacitance. These parts are suitable for circuits where higher voltage margin is required. Both are active production parts with ROHS3 compliance.

For Extended Temperature Range (Upgrade): EEA-GA1A220 (Panasonic) provides a 10 V rating with extended operating temperature range of -55°C ~ 105°C and extended lifetime of 1000 hours at 105°C. This part is suitable for applications requiring operation at elevated temperatures or wider temperature extremes.

All substitute parts are ROHS3 compliant and maintain through-hole radial can package configuration with 0.059" (1.50mm) lead spacing.

Frequently Asked Questions (FAQ)

Q: Can ECE-A0JKS220 be used as a direct replacement for 6.3MS522MEFC4X5? A: Yes. ECE-A0JKS220 matches the electrical specifications (22 µF, 6.3 V, ±20%, 1000 Hrs @ 85°C) and package type (radial, can, through-hole). The reduced height of 0.197" (5.00mm) versus the original 0.256" (6.50mm) must be verified for PCB layout compatibility.

Q: What is the difference between direct equivalents and upgrade parts? A: Direct equivalents maintain identical electrical and mechanical specifications as the original part. Upgrade parts enhance one or more parameters (voltage rating, lifetime, or temperature range) while maintaining the same capacitance value and package form factor.

Q: Can a 10 V rated capacitor replace a 6.3 V rated capacitor? A: Yes, from an electrical standpoint. A higher voltage rating provides additional safety margin in the circuit. However, physical dimensions may differ; verify PCB layout compatibility before substitution.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of the original 6.3MS522MEFC4X5.

Q: What is the significance of the 2000 hour lifetime in UMR0J220MCD2? A: UMR0J220MCD2 is rated for 2000 hours at 85°C, double the 1000 hour rating of the original part. This extended lifetime is beneficial for applications requiring longer operational life or higher reliability margins.

Q: Does lead spacing differ among substitute parts? A: No. All substitute parts maintain the same lead spacing of 0.059" (1.50mm), ensuring PCB footprint compatibility.

Q: Which substitute part has the smallest physical height? A: ECE-A0JKS220 has the smallest height at 0.197" (5.00mm), compared to the original 0.256" (6.50mm). This reduced height may provide layout advantages in space-constrained applications.
