EEU-HD1C682 Equivalent & Substitute Parts

Part Overview

The EEU-HD1C682 is a 6800 µF, 16 V aluminum electrolytic capacitor in radial, can package manufactured by Panasonic Electronic Components. This capacitor is rated for 2000 hours at 105°C and is designed for general-purpose applications requiring stable capacitance and ripple current handling. The part is currently Active in product status and fully compliant with RoHS3 and REACH regulations.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements allow for equivalent electrical and mechanical specifications. Panasonic offers direct packaging variants, while Nichicon provides parametrically equivalent alternatives that maintain the same core electrical performance within specified tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEU-HD1C682 is determined by strict equivalence across the following parameters:

• Capacitance: 6800 µF (exact match required)
• Voltage Rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime: 2000 Hrs @ 105°C (exact match required)
• Operating Temperature: -55°C to 105°C (exact match required)
• Polarization: Polar (exact match required)
• Lead Spacing: 7.50 mm (exact match required)
• Diameter: 16.00 mm (exact match required)
• Height: 27.00 mm maximum (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial, Can (exact match required)

Substitutes are grouped into two categories:

Direct Manufacturer Substitutes: Parts from Panasonic Electronic Components with identical electrical and mechanical specifications but different packaging formats (Bulk vs. Cut Tape).

Parametric Equivalents: Parts from alternative manufacturers (Nichicon) that meet all core electrical and mechanical parameters while maintaining functional compatibility in the application circuit.

Engineering Selection Recommendations

Primary Selection: EEU-HD1C682 (Panasonic, Bulk Packaging)

The EEU-HD1C682 is the recommended primary choice for new designs. It maintains Active product status, ensuring long-term availability and manufacturer support. This part is suitable for applications requiring standard bulk component procurement.

Secondary Selection: EEU-HD1C682B (Panasonic, Cut Tape Packaging)

The EEU-HD1C682B is a direct equivalent from Panasonic with identical electrical and mechanical specifications. The only difference is packaging format (Cut Tape vs. Bulk). This part is appropriate when automated assembly processes or tape-and-reel handling is required. Product status remains Active, maintaining design continuity.

Tertiary Selection: UVY1C682MHD (Nichicon, Bulk Packaging)

The UVY1C682MHD is a parametric equivalent from Nichicon that meets all core electrical and mechanical requirements. However, this part carries a "Not For New Designs" product status designation. Selection of this part should be limited to legacy system maintenance, repair operations, or situations where supply of Panasonic alternatives is unavailable. The ripple current specifications differ slightly (1.6 A @ 120 Hz vs. 1.78 A), which may be relevant in high-ripple-current applications.

All three parts are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can EEU-HD1C682B be used as a direct replacement for EEU-HD1C682?

A: Yes. Both parts are manufactured by Panasonic with identical electrical and mechanical specifications. The only difference is packaging format: EEU-HD1C682 is supplied in Bulk, while EEU-HD1C682B is supplied in Cut Tape (CT). Selection depends on procurement and assembly requirements, not circuit performance.

Q: Is the Nichicon UVY1C682MHD suitable for new product designs?

A: No. The UVY1C682MHD carries a "Not For New Designs" product status. It should be used only for legacy system support or repair applications. For new designs, select either the EEU-HD1C682 or EEU-HD1C682B from Panasonic.

Q: What is the significance of the ripple current difference between EEU-HD1C682 and UVY1C682MHD?

A: The EEU-HD1C682 specifies 1.78 A @ 120 Hz and 2.047 A @ 100 kHz. The UVY1C682MHD specifies 1.6 A @ 120 Hz and 1.84 A @ 10 kHz. In applications with high ripple current demands, particularly at high frequencies, the Panasonic part provides higher current handling capability. Verify ripple current requirements against the application circuit before selecting the Nichicon alternative.

Q: Are all three parts RoHS3 compliant?

A: Yes. All three parts—EEU-HD1C682, EEU-HD1C682B, and UVY1C682MHD—are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging supplies components loose in a container, suitable for manual assembly or small-volume procurement. Cut Tape (CT) packaging supplies components on adhesive tape in reels, optimized for automated pick-and-place assembly equipment. Both formats contain identical components; packaging selection depends on assembly process requirements.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes, provided the PCB footprint accommodates the specified lead spacing (7.50 mm) and component height (27.00 mm maximum). All three parts share identical mechanical dimensions and mounting type (Through Hole, Radial, Can), ensuring mechanical and electrical compatibility in the same circuit board layout.
