Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6SEPC470ME is determined by strict equivalence in the following electrical and mechanical parameters:

Electrical Equivalence Requirements:

• Capacitance: 470 µF (exact match)
• Voltage Rating: 6.3 V (exact match)
• Tolerance: ±20% (exact match)
• Type: Aluminum Polymer (exact match)
• Operating Temperature: -55°C to 105°C (exact match)
• Lifetime: 5000 Hrs @ 105°C (exact match)

Mechanical Compatibility Requirements:

• Mounting Type: Through Hole (exact match)
• Package Type: Radial, Can (exact match)
• Lead Spacing: 0.098" (2.50 mm) or 0.138" (4.60 mm) acceptable based on PCB design
• Physical Dimensions: Compatible with board layout constraints

Performance Characteristics:

• ESR values lower than or equal to 20 mOhm are acceptable substitutes
• Ripple current ratings at both 120 Hz and 100 kHz must meet or exceed application requirements

The substitute parts 6SEPC470M and 6SEPC470MW maintain all required electrical specifications while offering improved ESR performance and active product status.

Parameter Comparison

Engineering Selection Recommendations

6SEPC470M Substitution: This part is suitable for applications where PCB layout accommodates the larger 0.315" (8.00 mm) diameter and 0.512" (13.00 mm) height. The 8 mOhm ESR provides superior performance compared to the original 20 mOhm specification, with doubled ripple current capacity at both 120 Hz and 100 kHz. Active product status ensures long-term availability and supply chain continuity. ROHS3 compliance and REACH unaffected status maintain regulatory alignment with the original part.

6SEPC470MW Substitution: This part offers the most direct mechanical compatibility with the 6SEPC470ME, maintaining identical lead spacing (0.098", 2.50 mm) and diameter (0.248", 6.30 mm). The 7 mOhm ESR represents a 65% reduction from the original specification, with proportionally increased ripple current ratings. The intermediate height of 0.354" (9.00 mm) requires verification against PCB clearance constraints. Active product status, ROHS3 compliance, and REACH unaffected designation provide equivalent regulatory standing.

Both substitute parts maintain the full electrical specification envelope of the 6SEPC470ME while offering measurable performance improvements through reduced ESR and enhanced ripple current handling.

Frequently Asked Questions (FAQ)

Q: Can the 6SEPC470M be used as a direct replacement for the 6SEPC470ME?

A: Electrical substitution is complete. Mechanical compatibility requires PCB layout verification. The 6SEPC470M has a larger diameter (0.315" vs. 0.248") and greater height (0.512" vs. 0.276"), with different lead spacing (0.138" vs. 0.098"). Confirm available board space and component clearance before implementation.

Q: What is the primary advantage of the 6SEPC470MW over the original 6SEPC470ME?

A: The 6SEPC470MW reduces ESR from 20 mOhm to 7 mOhm, improving thermal performance and ripple current capacity by approximately 90%. Mechanical dimensions remain nearly identical, with only a modest height increase from 0.276" to 0.354", making it the preferred substitute for space-constrained applications.

Q: Are both substitute parts suitable for high-ripple-current applications?

A: Yes. The 6SEPC470M and 6SEPC470MW both exceed the original ripple current specifications at 120 Hz (285 mA and 280 mA respectively, versus 148.5 mA) and at 100 kHz (5.7 A and 5.6 A respectively, versus 2.97 A). Selection depends on available PCB space and thermal management requirements.

Q: Do the substitute parts maintain compliance with the original part's regulatory certifications?

A: Yes. Both 6SEPC470M and 6SEPC470MW are ROHS3 compliant and REACH unaffected, matching the regulatory status of the 6SEPC470ME. All three parts share identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications.

Q: Why is the 6SEPC470ME classified as obsolete?

A: Obsolescence reflects Panasonic's discontinuation of this specific variant. The active substitute parts 6SEPC470M and 6SEPC470MW provide equivalent or superior performance with assured long-term availability, making them the recommended alternatives for new designs and ongoing production.

Q: What is the impact of different lead spacing on PCB design?

A: Lead spacing determines the distance between through-hole pads on the PCB. The 6SEPC470ME and 6SEPC470MW use 0.098" (2.50 mm) spacing, while the 6SEPC470M uses 0.138" (4.60 mm). Existing PCB layouts designed for 2.50 mm spacing require modification to accommodate the 4.60 mm variant. The 6SEPC470MW eliminates this constraint.
