ECA-0JM682B Equivalent & Substitute Parts

Part Overview

The ECA-0JM682B is a 6800 µF, 6.3 V aluminum electrolytic capacitor in radial configuration manufactured by Panasonic Electronic Components. This component is rated for 2000 hours at 85°C and is designed for general-purpose applications requiring high capacitance in a compact through-hole package. The part is ROHS3 compliant and currently in active production status.

Equivalent and substitute parts are necessary when the original part becomes unavailable, when packaging requirements differ, or when enhanced performance characteristics are required for specific application environments.

Substitute Part Grouping Explanation

Substitute parts for the ECA-0JM682B are classified based on electrical and mechanical compatibility. All substitutes maintain identical capacitance (6800 µF), voltage rating (6.3 V), tolerance (±20%), and physical dimensions (lead spacing, case diameter, height). The primary differentiators are manufacturer, series designation, packaging format, product status, and thermal performance characteristics.

Substitution logic is based on the following allowed parameters:

Capacitance value and tolerance
Voltage rating
Physical dimensions and lead spacing
Mounting type (through-hole)
Package configuration (radial, can)
Polarization (polar)
Operating temperature range
Lifetime rating at specified temperature

Engineering Selection Recommendations

Direct Equivalent (Packaging Variant): ECA-0JM682 is the direct equivalent to ECA-0JM682B, differing only in packaging format (bulk versus tape & box). Both are Panasonic M-A series components with identical electrical specifications and active product status. Selection between these depends on procurement and assembly requirements.

Enhanced Thermal Performance: ECA-0JHG682 is an upgrade option from the Panasonic NHG-A series. It maintains identical capacitance, voltage, and physical dimensions while offering extended operating temperature range (-55°C ~ 105°C) and higher temperature lifetime rating (2000 Hrs @ 105°C). This part is ROHS3 compliant and in active production, making it suitable for applications requiring enhanced thermal performance.

Legacy Alternatives: UKW0J682MHD1TO, UVR0J682MHD, and UVK0J682MHD1TO are Nichicon equivalents with matching electrical and mechanical parameters. These parts are marked "Not For New Designs" and should be used only for legacy system maintenance or replacement applications where original component sourcing is critical.

All substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance with the original component.

Frequently Asked Questions (FAQ)

Q: Can ECA-0JM682 be used as a direct replacement for ECA-0JM682B?

A: Yes. Both parts are identical Panasonic M-A series components with the same electrical specifications (6800 µF, 6.3 V, ±20%, 2000 Hrs @ 85°C) and physical dimensions. The only difference is packaging format (bulk versus tape & box). Selection depends on assembly and procurement requirements.

Q: What is the advantage of ECA-0JHG682 over ECA-0JM682B?

A: ECA-0JHG682 extends the operating temperature range to -55°C ~ 105°C and provides 2000 hours lifetime at 105°C instead of 85°C. This makes it suitable for applications in higher temperature environments. Both parts maintain identical capacitance, voltage rating, and physical dimensions.

Q: Why are Nichicon parts marked "Not For New Designs"?

A: Parts designated "Not For New Designs" indicate that the manufacturer has discontinued active development and recommends alternative components for new applications. These parts remain available for legacy system support and replacement purposes.

Q: Are all substitute parts mechanically interchangeable?

A: Yes. All listed substitutes maintain identical lead spacing (0.197" / 5.00 mm), case diameter (0.492" / 12.50 mm), and height (1.063" / 27.00 mm). They are all through-hole radial can packages and are mechanically interchangeable in PCB layouts designed for the original component.

Q: What packaging options are available?

A: ECA-0JM682B is supplied in Tape & Box format. ECA-0JM682 is available in bulk packaging. Nichicon alternatives are available in Cut Tape (UKW0J682MHD1TO, UVK0J682MHD1TO) or bulk (UVR0J682MHD) formats. Packaging selection depends on assembly automation and procurement volume requirements.

Q: Are all parts ROHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance for electronics manufacturing and distribution.
