Engineering Selection Recommendations

For Direct Replacement (Same Electrical and Mechanical Specifications):

Select ECA-1CHG682 (Panasonic) or EEU-HD1C682 (Panasonic) as primary alternatives. Both components are Active product status, ROHS3 compliant, and provide identical electrical performance to the UVZ1C682MHD. EEU-HD1C682 offers the additional advantage of MSL 1 (Unlimited) moisture sensitivity rating.

For Extended Reliability Applications:

UPW1C682MHD (Nichicon, 8000 Hrs @ 105°C) provides the highest lifetime rating among 16 V substitutes. This part requires PCB layout verification due to increased case diameter (0.709" vs. 0.630"). UPJ1C682MHD (Nichicon, 5000 Hrs @ 105°C) offers intermediate reliability enhancement with the same diameter consideration.

For Voltage Margin Applications:

UVY1E682MHD (Nichicon, 25 V) or 25PX6800MEFC16X35.5 (Rubycon, 25 V) provide higher voltage rating while maintaining identical capacitance and tolerance. Both are ROHS3 compliant and Active status. Height verification is required (1.476" vs. 1.457" maximum).

For Active Product Status Requirement:

URZ1C682MHD (Nichicon, Active status) is the only Nichicon substitute with Active product status. This part features reduced lifetime (1000 Hrs @ 105°C) and increased case diameter (0.709"). EKMG160ELL682MLN3S (Chemi-Con, Active status) provides Active status with 1000 Hrs @ 105°C rating and standard 0.630" diameter.

Compliance Verification:

All listed substitutes are ROHS3 compliant and REACH unaffected. Cross-manufacturer substitution (Panasonic, Chemi-Con, Rubycon) is electrically and mechanically valid within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can UVY1C682MHD replace UVZ1C682MHD directly on the PCB?

A: Yes. Both components share identical electrical specifications (6800 µF, 16 V, ±20%, 2000 Hrs @ 105°C) and mechanical parameters (0.630" diameter, 0.295" lead spacing, Through Hole radial package). UVY1C682MHD has a reduced height (1.063" vs. 1.457"), which may provide additional PCB clearance.

Q: What is the difference between UPW1C682MHD and UVZ1C682MHD?

A: Both components have identical electrical specifications (6800 µF, 16 V, ±20%). The primary differences are: UPW1C682MHD has extended lifetime (8000 Hrs @ 105°C vs. 2000 Hrs), increased case diameter (0.709" vs. 0.630"), and higher ripple current ratings (3.128 A @ 120 Hz vs. 1.78 A). PCB layout verification is required for diameter change.

Q: Are Panasonic ECA-1CHG682 and EEU-HD1C682 interchangeable?

A: Both Panasonic parts are electrically equivalent (6800 µF, 16 V, ±20%, 2000 Hrs @ 105°C) with identical lead spacing and case diameter (0.630"). ECA-1CHG682 has height 1.319" while EEU-HD1C682 has height 1.063". Physical clearance must be verified for the specific application. EEU-HD1C682 offers MSL 1 (Unlimited) rating.

Q: Can a 25 V rated capacitor (UVY1E682MHD) replace a 16 V rated capacitor (UVZ1C682MHD)?

A: Yes. Higher voltage ratings are acceptable substitutes in applications designed for 16 V operation. UVY1E682MHD (25 V) and 25PX6800MEFC16X35.5 (25 V) both maintain identical capacitance (6800 µF) and tolerance (±20%). Height verification is required (1.476" vs. 1.457" maximum).

Q: What is the impact of reduced lifetime ratings (URZ1C682MHD at 1000 Hrs)?

A: URZ1C682MHD provides 1000 Hrs @ 105°C lifetime versus 2000 Hrs for UVZ1C682MHD. This represents a 50% reduction in thermal aging life. Selection is appropriate only for applications with lower thermal stress or shorter service life requirements. URZ1C682MHD is the only Nichicon substitute with Active product status.

Q: Does packaging format (Bulk vs. Cut Tape) affect electrical performance?

A: No. EEU-HD1C682B (Cut Tape packaging) and EEU-HD1C682 (Bulk packaging) are electrically and mechanically identical. Packaging format affects supply chain logistics and handling only, not component performance or compatibility.

Q: What are the ripple current implications when selecting substitutes?

A: Ripple current ratings vary among substitutes. UPW1C682MHD provides the highest ripple current capacity (3.128 A @ 120 Hz, 3.68 A @ 100 kHz), while URZ1C682MHD provides the lowest (1.56 A @ 120 Hz, 1.794 A @ 10 kHz). Selection should match application ripple current requirements. Higher ripple current capability provides thermal margin.

Q: Are cross-manufacturer substitutes (Panasonic, Chemi-Con, Rubycon) qualified for use?

A: Yes. All listed cross-manufacturer substitutes meet identical electrical and mechanical parameter requirements. All are ROHS3 compliant and REACH unaffected. Manufacturer qualification and supply chain considerations should be evaluated per organizational procurement standards.
