Substitute Part Grouping Explanation

Substitution for the 6.3MS747MEFC4X7 is determined by strict equivalence across the following parameters:

• Capacitance value: 47 µF (exact match required)
• Rated voltage: 6.3 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)
• Polarization: Polar (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial, Can (exact match required)
• Lead spacing: 0.059" (1.50mm) (exact match required)
• Physical dimensions: 0.157" Dia (4.00mm) (exact match required)

The ECE-A0JKA470 from Panasonic Electronic Components meets all these criteria and qualifies as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The ECE-A0JKA470 is the qualified equivalent substitute for the 6.3MS747MEFC4X7. Both components are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for equivalent applications. The substitute part is currently in active production status, ensuring long-term availability compared to the obsolete original part.

The ECE-A0JKA470 has a reduced seated height of 0.276" (7.00mm) compared to the original 0.315" (8.00mm), which may provide a minor advantage in space-constrained PCB layouts. Ripple current specifications are within acceptable operational ranges for both low-frequency and high-frequency applications.

Frequently Asked Questions (FAQ)

Q: Can the ECE-A0JKA470 be used as a direct replacement for the 6.3MS747MEFC4X7?

A: Yes. Both components share identical electrical specifications (47 µF, 6.3 V, ±20% tolerance, 1000 Hrs @ 85°C) and mechanical compatibility (through-hole mounting, radial can package, 0.059" lead spacing, 0.157" diameter). The substitute meets all substitution criteria.

Q: What is the difference in height between these two parts?

A: The ECE-A0JKA470 has a maximum seated height of 0.276" (7.00mm), while the 6.3MS747MEFC4X7 measures 0.315" (8.00mm). This 0.039" (1.00mm) difference may be relevant for applications with tight vertical clearance constraints.

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

A: No. Both parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory standards.

Q: Why is the original part obsolete?

A: The 6.3MS747MEFC4X7 is listed as obsolete by the manufacturer. The ECE-A0JKA470 is in active production status, providing assured long-term availability for equivalent applications.

Q: Do ripple current ratings differ between these parts?

A: Ripple current specifications vary slightly. At 120 Hz, the ECE-A0JKA470 provides 46 mA compared to 50 mA for the original. At 10 kHz, the substitute provides 78.2 mA compared to 75 mA for the original. Both ratings remain within acceptable operational parameters for general-purpose applications.
