SH471M6R3ST Equivalent & Substitute Parts Reference

Part Overview

The SH471M6R3ST is a 470 µF, 6.3 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, indicating that the original manufacturer has discontinued production. The SH series represents legacy technology in general-purpose applications requiring through-hole mounting with radial lead configuration.

Equivalent and substitute parts are necessary due to the obsolete status of the SH471M6R3ST. Active production alternatives from CDE and other manufacturers provide identical or superior electrical performance while maintaining mechanical compatibility with existing PCB designs.

Lead Spacing: 3.50 mm (PCB hole pattern compatibility)
Diameter: 8.00 mm (mechanical envelope)
Mounting Type: Through Hole (assembly process compatibility)
Package Type: Radial, Can (form factor)
Polarization: Polar (circuit function)

Upgradeable Parameters:

Voltage Rating: 6.3 V original; 10 V substitutes are acceptable (higher voltage provides design margin)
Operating Temperature Range: Original -40°C ~ 105°C; substitutes with -55°C ~ 105°C provide extended low-temperature operation
Lifetime @ Temperature: Original 2000 Hrs @ 105°C; longer lifetimes (3000, 5000, 6000 Hrs) represent performance improvements
ESR and Ripple Current: Lower values represent performance improvements

Compliance Requirements:

RoHS3 compliance maintained across all substitutes
REACH status documented where applicable

Substitutes are grouped into three categories: same-series upgrades (CDE SEK series), direct equivalents (Panasonic FC series), and alternative manufacturers (Nichicon UHE, UPW series).

Engineering Selection Recommendations

Primary Recommendation: SEK471M6R3ST

The SEK471M6R3ST is the direct active equivalent from Cornell Dubilier Electronics. It maintains identical electrical specifications (470 µF, 6.3 V, ±20%, 730 mOhm ESR, 2000 Hrs @ 105°C) and mechanical dimensions to the obsolete SH471M6R3ST while extending the operating temperature range to -55°C ~ 105°C. Product status is Active, ensuring long-term availability. This part requires no circuit redesign and provides the lowest risk substitution path.

Secondary Recommendation: SEK471M010ST

The SEK471M010ST provides voltage upgrade to 10 V while maintaining all other specifications. This substitution is valid when circuit design permits higher voltage rating. The improved ESR (620 mOhm vs. 730 mOhm) provides marginal performance benefit. Product status is Active with extended temperature range (-55°C ~ 105°C).

Panasonic FC Series (EEU-FC0J471, EEU-FC1A471)

Panasonic FC series parts are mechanically and electrically compatible. EEU-FC0J471 matches the 6.3 V rating; EEU-FC1A471 provides 10 V upgrade. Both carry AEC-Q200 automotive qualification and are Active products. These parts are suitable for applications requiring automotive-grade reliability.

Panasonic EB-A Series (EEU-EB1A471S)

The EEU-EB1A471S offers extended lifetime (5000 Hrs @ 105°C) at 10 V rating. Height is 12.50 mm (1 mm taller than original), requiring clearance verification. Product status is Active. This part is appropriate for applications with extended operational life requirements.

Nichicon UPW Series (UPW0J471MPD, UPW1A471MPD)

Nichicon UPW series parts provide mechanical compatibility with extended lifetime (3000 Hrs @ 105°C). Product status is Not For New Designs, indicating these parts are in mature phase. UPW0J471MPD maintains 6.3 V rating; UPW1A471MPD provides 10 V upgrade. These parts are suitable for legacy system maintenance and repair.

Nichicon UHE Series (UHE1A471MPD)

The UHE1A471MPD offers the longest lifetime (6000 Hrs @ 105°C) at 10 V rating. Product status is Not For New Designs. This part is appropriate for high-reliability applications requiring extended operational life, subject to REACH compliance verification for specific applications.

Frequently Asked Questions (FAQ)

Q: Can I use a 10 V rated capacitor in place of the 6.3 V original?

A: Yes. A higher voltage rating provides design margin and is electrically compatible. The circuit will function identically. Verify that PCB layout and mechanical clearance accommodate the substitute part.

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

A: Active products are in current production with guaranteed long-term availability. Not For New Designs indicates the manufacturer is phasing out the product but will continue limited production for existing customers. For new designs, select Active status parts. For legacy system repair, Not For New Designs parts are acceptable.

Q: Are all substitute parts mechanically interchangeable?

A: Mechanical interchangeability requires matching lead spacing (3.50 mm), diameter (8.00 mm), and height (11.50 mm maximum). The EEU-EB1A471S has 12.50 mm height and requires clearance verification. All other substitutes maintain 11.50 mm height.

Q: Does ESR (Equivalent Series Resistance) affect circuit function?

A: ESR affects ripple current handling and thermal performance. Lower ESR values represent improved performance. The original SH471M6R3ST has 730 mOhm ESR. Substitutes with lower ESR (such as SEK471M010ST at 620 mOhm) provide marginal improvement. For general-purpose applications, ESR differences within this range do not affect circuit function.

Q: What does RoHS3 compliance mean?

A: RoHS3 (Restriction of Hazardous Substances Directive 3) compliance certifies that the component does not contain restricted substances including lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, or polybrominated diphenyl ethers. All listed substitutes maintain RoHS3 compliance.

Q: Can I substitute a part with longer lifetime (5000 or 6000 Hrs @ 105°C) for the original 2000 Hrs?

A: Yes. Longer lifetime represents improved reliability and is a valid upgrade. The circuit will function identically. Longer lifetime parts do not introduce compatibility issues.

Q: What is the significance of operating temperature range differences?

A: The original SH471M6R3ST operates -40°C ~ 105°C. Substitutes with -55°C ~ 105°C range provide extended low-temperature operation. If your application operates below -40°C, select a substitute with -55°C minimum rating. For applications within -40°C ~ 105°C, both ranges are acceptable.

Q: Are Panasonic and Nichicon parts suitable for automotive applications?

A: Panasonic FC series parts carry AEC-Q200 automotive qualification. Nichicon UPW and UHE series do not list automotive ratings. For automotive applications, select Panasonic FC series (EEU-FC0J471 or EEU-FC1A471).

Q: What does "Impedance: 117 mOhms" mean on some parts?

A: Impedance is the total opposition to AC current flow at a specific frequency (typically 100 kHz). Lower impedance indicates better high-frequency performance. This parameter is provided for parts where ESR is not specified. For general-purpose applications, impedance differences within this range do not affect circuit function.
