SH471M100ST Equivalent & Substitute Parts Reference

Part Overview

The SH471M100ST is a 470 µF, 100 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, indicating discontinued production and limited availability for new procurement. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 2000 hours at 105°C, suitable for general-purpose applications requiring stable capacitance and moderate ripple current handling.

Due to obsolete status and finite inventory, equivalent substitute parts with matching or superior electrical and mechanical characteristics are necessary to ensure design continuity and long-term supply chain reliability.

Substitute Part Grouping Explanation

Substitution eligibility for the SH471M100ST is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Capacitance: 470 µF (exact)
Voltage Rating: 100 V (minimum)
Tolerance: ±20% (or tighter)
Package Type: Radial, Can
Mounting Type: Through Hole
Lead Spacing: 7.50 mm
Physical Dimensions: Compatible with 16.00 mm diameter and ≤32.00 mm height

Acceptable Variation Parameters:

ESR: Equal or lower values indicate improved performance
Lifetime @ Temperature: Equal or greater values indicate extended reliability
Operating Temperature Range: Equal or wider range indicates broader applicability
Ripple Current: Equal or higher values indicate enhanced current handling

All three substitute parts meet these mandatory criteria and are therefore electrically and mechanically compatible with the original SH471M100ST.

Engineering Selection Recommendations

SEK471M100ST (Cornell Dubilier Electronics)

The SEK471M100ST is the primary recommended substitute. It maintains identical electrical specifications to the original SH471M100ST while offering active product status, ensuring continued availability and manufacturing support. The extended operating temperature range (-55°C to 105°C) provides broader environmental compatibility. This part is suitable for direct replacement in existing designs without circuit modification.

EGPD101ELL471ML30H (Chemi-Con)

The EGPD101ELL471ML30H is recommended for applications requiring enhanced thermal performance and automotive-grade reliability. This part features AEC-Q200 certification, superior ESR characteristics (41 mOhm @ 100kHz), and extended lifetime rating at elevated temperature (2000 Hrs @ 135°C). The significantly higher ripple current capability (3.44 A @ 100kHz) accommodates demanding power supply applications. Physical height is marginally reduced (31.50 mm vs. 32.00 mm), ensuring PCB layout compatibility.

UPW2A471MHD (Nichicon)

The UPW2A471MHD offers extended operational lifetime (8000 Hrs @ 105°C) and is suitable for applications where long-term reliability is prioritized. However, this part carries "Not For New Designs" status, limiting its applicability to legacy system maintenance and repair scenarios. The extended temperature range (-55°C to 105°C) and improved ripple current handling (1.31 A @ 100kHz) provide performance advantages despite discontinued new design support.

Frequently Asked Questions (FAQ)

Q: Can the SEK471M100ST directly replace the SH471M100ST without PCB modification?

A: Yes. The SEK471M100ST maintains identical lead spacing (7.50 mm), diameter (16.00 mm), and maximum height (32.00 mm). No PCB layout changes are required for direct substitution.

Q: What is the primary advantage of the EGPD101ELL471ML30H over other substitutes?

A: The EGPD101ELL471ML30H provides automotive-grade AEC-Q200 certification, significantly lower ESR (41 mOhm @ 100kHz), and superior ripple current capacity (3.44 A @ 100kHz). These characteristics make it optimal for high-current power supply applications and automotive environments.

Q: Why is the UPW2A471MHD marked "Not For New Designs"?

A: This designation indicates that Nichicon has discontinued active promotion and development support for this part series. While existing inventory remains available for legacy applications, new product designs should prioritize the SEK471M100ST or EGPD101ELL471ML30H.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All three substitute parts carry ROHS3 Compliant certification, matching the environmental compliance status of the original SH471M100ST.

Q: What is the difference between ESR specifications at different frequencies?

A: ESR varies with frequency due to internal impedance characteristics. The EGPD101ELL471ML30H specifies ESR at 100kHz (41 mOhm), while the original and SEK specify at 120Hz (280 mOhm). Lower ESR at higher frequencies indicates superior performance in switching power supply applications.

Q: Can these parts be used interchangeably in all applications?

A: Yes, within the scope of the specified electrical and mechanical parameters. All parts meet the mandatory criteria: 470 µF capacitance, 100 V rating, ±20% tolerance, radial can package, and 7.50 mm lead spacing. Application-specific requirements (temperature extremes, ripple current demands, automotive certification) may favor one substitute over others.

Q: What inventory levels are available for each substitute?

A: SEK471M100ST: 1006 pieces; EGPD101ELL471ML30H: 1315 pieces; UPW2A471MHD: 4456 pieces. The UPW2A471MHD offers the highest immediate availability.
