Engineering Selection Recommendations

Primary Selection Criteria:

All listed substitute parts are electrically and mechanically equivalent to SH472M016ST. Selection among active alternatives should be based on the following factors:

1. Lifetime Requirements

Parts with 10000 hours @ 105°C lifetime (Rubycon YXJ, ZLH, ZLJ series; Panasonic EEU-FR1C472; Cornell Dubilier 478KBM016M) provide extended operational life compared to the original 2000-hour specification. These are suitable for applications requiring long-term reliability.

Parts with 2000 hours @ 105°C lifetime (Cornell Dubilier 478CKE016M, 478CKH016M) match the original specification and are appropriate for applications with defined replacement cycles.

The 6000-hour variant (Rubycon 16ZLQ4700MEFC16X20) provides intermediate lifetime performance.

2. Physical Height Constraints

Original SH472M016ST height: 32.00 mm (maximum seated)

Compact alternatives (27.00 mm height): Rubycon YXJ, ZLH, ZLJ series; Panasonic EEU-FR1C472. These are suitable for space-constrained PCB layouts.

Ultra-compact alternative (22.00 mm height): Rubycon 16ZLQ4700MEFC16X20. Use only where vertical space is severely limited and 6000-hour lifetime is acceptable.

Height-matched alternatives (31.50–32.00 mm): Cornell Dubilier 478CKH016M, 478KBM016M. These maintain original form factor for direct replacement without PCB redesign.

3. Impedance / ESR Performance

Lower impedance variants (13–17 mOhms from Rubycon ZLH, ZLJ series; 14 mOhms from Panasonic EEU-FR1C472; 14 mOhms from Rubycon ZLQ) provide superior high-frequency ripple current handling and reduced thermal dissipation.

Original ESR specification (70 mOhm @ 120 Hz) is matched by Cornell Dubilier variants (84.7–85 mOhm @ 120 Hz), which are functionally equivalent for low-frequency applications.

4. Compliance & Availability

All substitute parts are ROHS3 compliant and carry REACH Unaffected status where specified. All are currently in active production with confirmed inventory availability.

5. Manufacturer Continuity

For designs requiring single-source qualification, Cornell Dubilier 478CKE016M, 478CKH016M, or 478KBM016M maintain the original manufacturer lineage while offering active product status.

For designs open to multi-source qualification, Rubycon and Panasonic alternatives provide additional supply chain redundancy.

Frequently Asked Questions (FAQ)

Q: Can SH472M016ST be directly replaced with any of the listed substitutes?

A: Yes. All listed parts maintain identical capacitance (4700 µF), voltage rating (16 V), tolerance (±20%), package type (radial can), mounting type (through hole), lead spacing (7.50 mm), and diameter (16.00 mm). Direct functional equivalence is confirmed for all listed alternatives.

Q: What is the difference between the Rubycon YXJ, ZLH, ZLJ, and ZLQ series?

A: All four series share identical electrical specifications (4700 µF, 16 V, ±20%). Differences are in physical height and impedance performance. YXJ, ZLH, and ZLJ variants are 27.00 mm height with 10000-hour lifetime. ZLQ is 22.00 mm height with 6000-hour lifetime. ZLH series offers the lowest impedance (13 mOhms), followed by ZLJ (17 mOhms) and YXJ (21 mOhms).

Q: Will substituting with a lower-height part require PCB redesign?

A: Compact variants (22.00–27.00 mm) are shorter than the original 32.00 mm. If the PCB layout includes height-dependent traces, component placement, or mechanical constraints, verification is necessary. Height-matched alternatives (Cornell Dubilier 478CKH016M at 31.50 mm or 478KBM016M at 32.00 mm) eliminate this consideration.

Q: What is the advantage of 10000-hour lifetime over 2000-hour lifetime?

A: The 10000-hour specification at 105°C indicates the capacitor maintains specified electrical parameters for five times longer under elevated temperature stress. This extends the operational life of the circuit and reduces maintenance frequency. Selection depends on application duty cycle and replacement cost considerations.

Q: Are the Cornell Dubilier CKE, CKH, and KBM series interchangeable?

A: Yes, electrically and mechanically. 478CKE016M and 478CKH016M both specify 2000-hour lifetime and 84.7 mOhm ESR @ 120 Hz. 478KBM016M specifies 10000-hour lifetime and 85 mOhm ESR @ 120 Hz. Physical heights differ (26.50 mm, 31.50 mm, and 32.00 mm respectively), so PCB fit must be verified.

Q: Can I use the Panasonic EEU-FR1C472 as a direct replacement?

A: Yes. The EEU-FR1C472 matches all core electrical and mechanical specifications. It offers 10000-hour lifetime, 14 mOhm impedance, and 27.00 mm height. Verify that the reduced height (compared to original 32.00 mm) does not conflict with PCB layout constraints.

Q: What does "ROHS3 Compliant" mean for this application?

A: ROHS3 Compliant indicates the capacitor meets Restriction of Hazardous Substances Directive 3 requirements, restricting lead, mercury, cadmium, hexavalent chromium, and specified brominated flame retardants. All listed substitutes carry this certification, ensuring regulatory compliance for commercial and industrial applications.

Q: If I need the exact same height as the original SH472M016ST, which substitute should I use?

A: Cornell Dubilier 478KBM016M matches the original 32.00 mm height exactly. This part also offers 10000-hour lifetime, providing improved reliability while maintaining the original form factor.

Q: What is the difference between impedance and ESR?

A: Equivalent Series Resistance (ESR) is measured at a specific frequency (typically 120 Hz for these parts). Impedance is the total opposition to current flow, including both resistance and reactance components, typically measured at higher frequencies (100 kHz). Lower values in both parameters indicate better high-frequency performance and reduced thermal dissipation.
