URZ2G680MRD Equivalent & Substitute Parts

Part Overview

The URZ2G680MRD is a 68 µF, 400 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This part is classified as obsolete, with a rated lifetime of 1000 hours at 105°C. Due to its obsolete status and limited operational lifespan compared to modern alternatives, equivalent substitute parts with extended lifetime ratings and active product status are available from both Nichicon and alternative manufacturers. Substitutes maintain the core electrical specifications while offering improved reliability and longer service life.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the URZ2G680MRD are selected based on strict electrical and mechanical compatibility criteria. All substitutes maintain the following core parameters:

• Capacitance: 68 µF (exact match)
• Voltage Rating: 400 V (exact match)
• Tolerance: ±20% (exact match)
• Polarization: Polar (exact match)
• Mounting Type: Through Hole (exact match)
• Package Type: Radial, Can (exact match)
• Operating Temperature Range: -40°C ~ 105°C (exact match)
• RoHS3 Compliance: All substitutes maintain compliance

Substitutes are grouped by manufacturer series and lifetime rating. Mechanical dimensions (lead spacing, diameter, height) vary among substitutes but remain within through-hole radial can package specifications. All substitute parts are either Active or Not For New Designs status, providing improved availability and extended operational lifespan compared to the obsolete URZ2G680MRD.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute parts should be based on the following criteria:

For Active Product Status Priority: UCY2G680MHD, UCY2G680MHD3, UAQ2G680MHD, UAQ2G680MHD6, and EKXG401ELL680MM25S are all classified as Active, ensuring continued availability and manufacturing support. These parts are preferred over UVY2G680MHD, which is marked Not For New Designs.

For Extended Lifetime: UCY2G680MHD and UCY2G680MHD3 offer 12000 hours at 105°C, providing a 12-fold improvement over the original URZ2G680MRD. EKXG401ELL680MM25S provides 10000 hours at 105°C. These extended lifetimes are suitable for applications requiring long-term reliability.

For Intermediate Lifetime: UAQ2G680MHD and UAQ2G680MHD6 provide 2000 hours at 105°C, a 2-fold improvement over the original part, with Active status and established supply chains.

For Mechanical Fit: UCY2G680MHD3 offers the most compact height (1.043") among high-lifetime alternatives, suitable for space-constrained applications. EKXG401ELL680MM25S provides the lowest profile (0.984") among all substitutes.

For Cross-Manufacturer Compatibility: EKXG401ELL680MM25S from Chemi-Con maintains full electrical equivalence and offers Active status with extended lifetime, providing supply chain diversification.

All substitute parts maintain ROHS3 compliance. UCY series parts are REACH Affected; all others are REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can URZ2G680MRD be directly replaced with any of these substitutes?

A: Yes, all listed substitutes maintain identical electrical specifications (68 µF, 400 V, ±20% tolerance) and through-hole radial can packaging. Direct electrical substitution is valid. Mechanical fit depends on PCB layout and lead spacing requirements.

Q: What is the primary reason to substitute the URZ2G680MRD?

A: The URZ2G680MRD is obsolete with only 1000 hours lifetime at 105°C. All substitutes offer either Active status or extended operational lifespan, ensuring long-term availability and improved reliability.

Q: Which substitute offers the best long-term reliability?

A: UCY2G680MHD and UCY2G680MHD3 provide 12000 hours at 105°C, the highest lifetime rating among all options. EKXG401ELL680MM25S from Chemi-Con offers 10000 hours at 105°C with Active status.

Q: Are there mechanical dimension differences I need to consider?

A: Yes. Lead spacing varies from 0.197" (5.00mm) to 0.394" (10.00mm). Height ranges from 0.984" to 1.654". Verify PCB footprint compatibility before selection. UCY2G680MHD3 and EKXG401ELL680MM25S offer compact heights suitable for space-constrained designs.

Q: What is the difference between Active and Not For New Designs status?

A: Active parts are in full production with guaranteed availability. Not For New Designs (UVY2G680MHD) indicates the manufacturer is phasing out the product; it may still be available but is not recommended for new circuit designs.

Q: Can I use EKXG401ELL680MM25S from Chemi-Con as a substitute?

A: Yes. EKXG401ELL680MM25S maintains all core electrical specifications, is ROHS3 compliant, and offers 10000 hours lifetime at 105°C with Active status. It provides cross-manufacturer supply chain flexibility.

Q: Which substitute has the highest ripple current rating?

A: UCY2G680MHD3 provides 735 mA at 120 Hz and 1.47 A at 100 kHz, the highest ripple current capacity among all substitutes, suitable for high-current applications.
