16MS547MEFC5X5 Equivalent & Substitute Parts

Part Overview

The 16MS547MEFC5X5 is a 47 µF, 16 V aluminum electrolytic capacitor in radial configuration manufactured by Rubycon. This component is rated for 1000 hours at 85°C and is designed for general-purpose applications requiring through-hole mounting. The part is currently obsolete, making identification of compatible substitutes essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution of the 16MS547MEFC5X5 is determined by strict equivalence across the following parameters:

Capacitance Value: 47 µF (exact match required)
Voltage Rating: 16 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime Rating: 1000 Hrs @ 85°C (exact match required)
Operating Temperature Range: -40°C ~ 85°C (exact match required)
Lead Spacing: 0.079" (2.00mm) (exact match required)
Case Diameter: 0.197" (5.00mm) (exact match required)
Mounting Configuration: Through Hole, Radial (exact match required)
Polarization: Polar (exact match required)

The ECE-A1CKA470 from Panasonic Electronic Components meets all substitution criteria and is classified as a direct equivalent.

Engineering Selection Recommendations

The ECE-A1CKA470 is a direct functional equivalent to the 16MS547MEFC5X5. Both components satisfy identical electrical and mechanical specifications across all critical parameters. The ECE-A1CKA470 offers the additional advantage of active product status with established supply chain availability, whereas the original Rubycon part is obsolete.

Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications requiring environmental compliance certification. The marginal height difference of 0.020" (0.50mm) between the two parts remains within standard PCB layout tolerances for through-hole radial capacitor mounting.

Frequently Asked Questions (FAQ)

Q: Can the ECE-A1CKA470 be used as a direct replacement for the 16MS547MEFC5X5?

A: Yes. The ECE-A1CKA470 meets all electrical and mechanical specifications of the original part, including capacitance, voltage rating, tolerance, lifetime rating, operating temperature range, lead spacing, and case diameter. No circuit modifications are required.

Q: What is the significance of the height difference between the two parts?

A: The ECE-A1CKA470 has a maximum seated height of 0.276" (7.00mm) compared to 0.256" (6.50mm) for the 16MS547MEFC5X5. This 0.020" (0.50mm) difference is within standard PCB design clearance tolerances for through-hole components and does not affect functional compatibility or mounting.

Q: Are there compliance differences between the original and substitute part?

A: No. Both components are ROHS3 compliant and REACH unaffected. Regulatory compliance status is identical.

Q: Why is the original part listed as obsolete?

A: The 16MS547MEFC5X5 from Rubycon's MS5 series has reached end-of-life status. The ECE-A1CKA470 from Panasonic's active KA series provides continued availability for this specification class.

Q: Are ripple current ratings a consideration for substitution?

A: The ECE-A1CKA470 provides ripple current specifications (70 mA @ 120 Hz, 119 mA @ 10 kHz) that were not documented for the original part. These values represent the substitute's performance capability and do not affect compatibility with applications designed for the original component.
