Substitute Part Grouping Explanation

Substitution eligibility for the 827KXM063M is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Capacitance: 820 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 63 V (exact match required)
• Polarization: Polar (exact match required)
• Package Type: Radial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.295" (7.50 mm) (exact match required)
• Physical Diameter: 0.630" (16.00 mm) (exact match required)
• Operating Temperature Range: -55°C to 105°C (exact match required)
• Compliance: ROHS3 Compliant (exact match required)

Performance Parameters (Allowable Variation):

• ESR (Equivalent Series Resistance): Lower values are acceptable
• Lifetime @ Temperature: Equal or greater values are acceptable
• Ripple Current Ratings: Equal or greater values are acceptable
• Impedance: Lower values are acceptable

The substitute parts UPW1J821MHD and UPJ1J821MHD meet all mandatory equivalence criteria and are therefore qualified as direct substitutes for the 827KXM063M.

Parameter Comparison

Engineering Selection Recommendations

827KXM063M (Cornell Dubilier / Illinois Capacitor)

The 827KXM063M is the primary reference component with Active product status. This part is suitable for new designs and ongoing production. With 870 pieces in stock, it provides immediate availability for current applications.

UPW1J821MHD (Nichicon)

The UPW1J821MHD is a direct substitute with superior performance characteristics. It offers 8000 hours lifetime at 105°C compared to the 5000-hour rating of the main part, representing a 60% improvement in thermal endurance. Ripple current ratings are higher across both frequency bands (2.003 A @ 120 Hz and 2.67 A @ 100 kHz), and impedance is lower at 43 mOhms. However, this part carries "Not For New Designs" status, limiting its use to legacy system support or replacement applications. Inventory availability is strong at 1575 pieces.

UPJ1J821MHD (Nichicon)

The UPJ1J821MHD is a parametric equivalent with matching 5000-hour lifetime at 105°C. It provides improved ripple current performance (1.88 A @ 120 Hz and 2.22 A @ 100 kHz) and lower impedance (40 mOhms) relative to the main part. Like UPW1J821MHD, this part is designated "Not For New Designs." Inventory of 1080 pieces supports substitution requirements. The physical height is identical to the main part at 1.457" (37.00 mm), ensuring direct mechanical compatibility.

All three parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for both new and legacy applications.

Frequently Asked Questions (FAQ)

Q: Can UPW1J821MHD or UPJ1J821MHD be used as direct replacements for 827KXM063M on existing circuit boards?

A: Yes. Both Nichicon parts meet all mandatory electrical and mechanical parameters. Lead spacing (0.295" / 7.50 mm), physical diameter (0.630" / 16.00 mm), and mounting type (through-hole radial) are identical. The substitute parts will fit existing PCB layouts without modification.

Q: What is the difference between UPW1J821MHD and UPJ1J821MHD?

A: Both parts share identical capacitance, voltage, tolerance, and physical dimensions. The primary differences are: (1) UPW1J821MHD offers 8000-hour lifetime at 105°C versus 5000 hours for UPJ1J821MHD; (2) UPW1J821MHD has slightly higher ripple current ratings; (3) UPW1J821MHD has lower impedance (43 mOhms vs. 40 mOhms). Both are designated "Not For New Designs."

Q: Why are UPW1J821MHD and UPJ1J821MHD marked "Not For New Designs"?

A: This designation indicates that while these parts remain available and fully functional, the manufacturers recommend using alternative current-generation products for new design initiatives. These parts are suitable for replacement, repair, and legacy system support where the specific part number is already established in production.

Q: Are there any height differences between these three capacitors?

A: The 827KXM063M and UPJ1J821MHD both have a maximum seated height of 1.457" (37.00 mm). The UPW1J821MHD has a lower profile at 1.240" (31.50 mm). This 0.217" (5.50 mm) difference may be relevant for applications with height constraints, though all three fit the same lead spacing and diameter specifications.

Q: Do all three parts meet current compliance standards?

A: Yes. All three capacitors are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for both new and legacy applications.

Q: Which substitute part offers the best performance improvement?

A: UPW1J821MHD provides the most significant performance gains: 60% longer thermal life (8000 vs. 5000 hours), higher ripple current capacity, and lower impedance. However, its "Not For New Designs" status restricts its use to replacement and legacy applications.
