477CKH016M

Part Overview

The 477CKH016M is a 470 µF, 16 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the CKH series. This radial, through-hole component is rated for general-purpose applications with a 2000-hour lifetime at 105°C and is currently in Active product status. Alternative models are necessary to accommodate varying performance requirements, extended operational lifetimes, higher voltage ratings, and different manufacturing sources while maintaining electrical and mechanical compatibility within the 470 µF, 16-25 V radial can package class.

Substitute Part Grouping Explanation

Substitutes are categorized based on the following substitution criteria:

Direct Substitutes share identical electrical specifications (470 µF, 16 V, ±20% tolerance) and physical dimensions, differing only in ESR characteristics, ripple current ratings, or manufacturing series. These parts are interchangeable with no design modifications required.

Upgrade Substitutes maintain the 470 µF capacitance and ±20% tolerance while offering improved performance through extended lifetime (4000-10000 hours at 105°C versus 2000 hours), reduced ESR, or higher ripple current handling. These include both 16 V and 25 V voltage-rated options. The 25 V parts are electrically and mechanically compatible drop-ins for 16 V applications and provide additional voltage margin in designs operating near rated limits.

Key Substitution Parameters:

Capacitance: 470 µF (exact match required)
Voltage Rating: 16 V minimum; 25 V acceptable as upgrade
Lead Spacing: 0.197" (5.00mm)
Package Diameter: 0.394" (10.00mm)
Height: 0.551" (14.00mm) maximum
Mounting Type: Through Hole
Polarization: Polar
RoHS3 Compliance required

Engineering Selection Recommendations

For New Designs: Specify 477KXM016MLN (Cornell Dubilier, Active status, 4000-hour lifetime) as primary selection for extended operational life with Active product status. Alternatively, specify ESC477M016AH1AA (KEMET, Active status) for applications requiring reduced ESR performance. For designs with voltage headroom, 477CKE025M (Cornell Dubilier, Active), 25YXJ470M10X12.5 (Rubycon, Active), or 25ZLH470MEFC10X12.5 (Rubycon, Active) offer higher voltage ratings and extended lifetimes up to 10000 hours at 105°C while maintaining identical physical footprints.

For Legacy System Maintenance: UPS1C471MPD (Nichicon, not recommended for new designs) maintains electrical compatibility for repair applications but should not be specified for new production. Rubycon YXF, YXH, and ZL series parts (marked Last Time Buy or Not For New Designs) are available for existing inventory requirements but require transition planning to alternative Active-status sources.

Physical Compatibility: All substitute parts maintain standard 0.197" (5.00mm) lead spacing, 0.394" (10.00mm) radial can diameter, and 0.551" (14.00mm) maximum height (except ESC477M016AH1AA at 0.531" height, which is dimensionally suitable). Through-hole PCB mounting requirements remain constant across all listed substitutes.

Frequently Asked Questions (FAQ)

Q: Can I substitute a 25 V rated capacitor for a 16 V application? A: Yes. 477CKE025M, 25YXJ470M10X12.5, and 25ZLH470MEFC10X12.5 are electrically and mechanically compatible direct replacements. The higher voltage rating provides additional design margin and typically extends operational lifetime at rated temperature.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts are ROHS3 Compliant and REACH Unaffected, maintaining compliance with current industry standards.

Q: What is the difference between direct substitutes and upgrade substitutes? A: Direct substitutes (477KXM016MLN, ESC477M016AH1AA, UPS1C471MPD) maintain 16 V voltage ratings and 2000-hour lifetimes at 105°C. Upgrade substitutes offer either extended lifetimes (4000-10000 hours) at 105°C or higher voltage ratings (25 V) with corresponding performance improvements in ripple current handling or ESR characteristics.

Q: Which substitute should I use if the 477CKH016M is unavailable? A: For Active product status with continuous availability, select 477KXM016MLN (4000-hour lifetime upgrade) or 16ZLG470MEFC10X12.5 (Active status, 4000-hour lifetime). Both maintain identical physical footprints and electrical specifications with superior performance characteristics.

Q: Is the KEMET ESC477M016AH1AA compatible with existing PCB designs? A: Yes, with verification. ESC477M016AH1AA has identical lead spacing (0.197" / 5.00mm) and radial can diameter (0.394" / 10.00mm) but measures 0.531" maximum seated height versus 0.551" for Cornell Dubilier and Rubycon parts. This 0.02" difference permits substitution on standard PCBs with no layout modifications required.

Q: Why are some Rubycon parts marked "Last Time Buy"? A: Last Time Buy designation indicates limited remaining inventory and imminent discontinuation. 16YXH470MEFC10X12.5 and 16ZL470MEFC10X12.5 are available for maintenance and repair but should not be selected for new production. Transition to Active-status alternatives such as 16ZLG470MEFC10X12.5 or Cornell Dubilier options.

Q: What does "Not For New Designs" mean for the Nichicon UPS1C471MPD? A: This designation indicates the part is obsolete or nearing end-of-life for new production but remains available for legacy system support. Use only for repair applications where design continuity with existing equipment is required. All new designs should specify Active-status alternatives.
