SH471M025ST Equivalent & Substitute Parts Reference

Part Overview

The SH471M025ST is a 470 µF, 25 V aluminum electrolytic capacitor in radial can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, with 718 units currently in stock. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 2000 hours at 105°C and an equivalent series resistance (ESR) of 450 mOhm at 120 Hz.

Due to its obsolete status, direct replacement with active production equivalents is necessary for new designs and long-term supply chain continuity. Substitute parts must maintain electrical compatibility across capacitance, voltage rating, tolerance, and mechanical dimensions while meeting or exceeding performance specifications.

Engineering Selection Recommendations

Primary Recommendation for Active Production:

SEK471M025ST (Cornell Dubilier Electronics) is the direct upgrade path from the obsolete SH471M025ST. Both components are manufactured by the same supplier, share identical electrical specifications (470 µF, 25 V, ±20%, 2000 Hrs @ 105°C), and maintain the same mechanical footprint. The SEK series extends the operating temperature range to -55°C to 105°C, providing enhanced thermal performance. Product status is Active with 1268 units in stock.

Secondary Recommendations for Extended Lifetime Applications:

When application requirements demand extended operational lifetime beyond 2000 hours at 105°C, the following active production alternatives provide superior reliability:

25YXJ470MCE10X12.5 or 25YXJ470M10X12.5 (Rubycon YXJ Series): 10000-hour lifetime at 105°C. Height reduced to 14.00 mm. 10734 units available. Suitable for applications requiring maximum reliability over extended service periods.
EEU-EB1E471 (Panasonic EB-A Series): 10000-hour lifetime at 105°C. Height 17.00 mm. 10269 units available. Panasonic active production status ensures long-term supply continuity.
EKY-250ELL471MJ16S (Chemi-Con KY Series): 7000-hour lifetime at 105°C. Height 17.50 mm. 5434 units available. Intermediate lifetime option with high ripple current capability (1.21 A @ 100 kHz).
EKZE250ELL471MJ16S (Chemi-Con KZE Series): 4000-hour lifetime at 105°C. Height 17.50 mm. 61340 units in stock (highest inventory). Lowest impedance (38 mOhms) among active alternatives.

Automotive Applications:

EEU-FC1E471 (Panasonic FC Series) carries AEC-Q200 automotive qualification. 3000-hour lifetime at 105°C. 873 units available. Suitable for automotive-grade applications requiring formal qualification documentation.

Obsolete Status Alternatives:

517D477M025CD6AE3 (Vishay Sprague 517D Series) maintains identical 2000-hour lifetime and 16.00 mm height but carries obsolete product status. Use only when existing inventory must be depleted or when new design qualification is not required.

Not For New Designs Status:

UHD1E471MPD6 and UHE1E471MPD6 (Nichicon UHD and UHE Series) carry "Not For New Designs" status. These parts are available in high inventory (9502 and 164986 units respectively) but should not be selected for new product development. Use only for legacy system maintenance or repair applications.

Frequently Asked Questions (FAQ)

Q1: Can I use a substitute part with a different height than the original SH471M025ST?

A: Height variation is permissible within the constraints of your PCB layout and mechanical assembly. The SH471M025ST has a maximum seated height of 16.00 mm. Substitute parts range from 14.00 mm (Rubycon YXJ series) to 17.50 mm (Chemi-Con KY and KZE series). Verify clearance in your specific application before selection. All alternatives maintain the identical 10.00 mm diameter and 5.00 mm lead spacing.

Q2: What is the difference between "Active," "Not For New Designs," and "Obsolete" product status?

A: Active status indicates the manufacturer currently produces the part and commits to long-term supply. "Not For New Designs" status means the manufacturer no longer recommends the part for new applications but may continue limited production for legacy support. Obsolete status indicates the manufacturer has discontinued production. For new designs, select only Active status parts. For legacy system maintenance, "Not For New Designs" parts are acceptable if inventory is available.

Q3: Why do some substitute parts have significantly longer lifetimes (10000 hours vs. 2000 hours)?

A: Lifetime rating reflects the expected operational duration at maximum rated temperature (105°C) before capacitance degradation exceeds the tolerance specification. Extended lifetime results from improved internal construction, superior electrolyte formulations, and enhanced thermal management. Selection depends on application requirements. General-purpose applications may not require extended lifetime, while critical infrastructure or aerospace applications typically demand maximum reliability.

Q4: What does ESR (Equivalent Series Resistance) mean, and why does it vary among substitutes?

A: ESR represents the internal resistance of the capacitor at a specified frequency (typically 120 Hz or 10 kHz). Lower ESR reduces heat generation and improves high-frequency performance. The original SH471M025ST specifies 450 mOhm at 120 Hz. Substitute parts with lower impedance values (such as EKZE250ELL471MJ16S at 38 mOhms) provide superior performance in ripple current applications. For general-purpose circuits, ESR variation within the specified range does not affect functionality.

Q5: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 Compliant status, matching the original SH471M025ST. This ensures compatibility with environmental regulations and procurement requirements across all major markets.

Q6: Can I substitute a part with a wider operating temperature range?

A: Yes. The original SH471M025ST operates from -40°C to 105°C. Substitute parts with extended ranges (such as -55°C to 105°C) are fully compatible and provide additional margin for extreme environmental conditions. Wider temperature ranges do not introduce compatibility issues in applications designed for the original temperature specification.

Q7: What is the difference between ripple current at 120 Hz and 100 kHz?

A: Ripple current rating specifies the maximum AC current the capacitor can withstand at a given frequency without exceeding temperature limits. Low-frequency ripple current (120 Hz) is relevant for power supply filtering in 50/60 Hz AC systems. High-frequency ripple current (100 kHz) is critical for switching power supplies and high-frequency converter applications. The original SH471M025ST supports 470 mA @ 120 Hz and 564 mA @ 10 kHz. Substitute parts with higher ripple current ratings provide additional design margin.

Q8: Why is inventory quantity listed for each part?

A: Inventory availability directly impacts procurement timeline and cost. Parts with high inventory (such as EKZE250ELL471MJ16S with 61340 units) offer immediate availability and stable pricing. Parts with limited inventory (such as 25YXJ470MCE10X12.5 with 817 units) may require longer lead times or price negotiation. Verify current inventory status with your supplier before final selection.

Q9: What does "Bulk" packaging mean?

A: Bulk packaging indicates the parts are supplied in standard industrial quantities (typically 1000-unit reels or tape-and-reel format) rather than individual component packaging. This is standard for through-hole radial capacitors and does not affect electrical or mechanical compatibility.

Q10: Should I select the substitute with the longest lifetime for all applications?

A: Lifetime selection should match application requirements. Extended lifetime (10000 hours) is beneficial for critical infrastructure, aerospace, or long-service-life consumer products. General-purpose applications may not justify the cost premium of extended-lifetime parts. The original SH471M025ST specifies 2000 hours, indicating this lifetime is sufficient for the intended application class. Select substitute parts with equal or greater lifetime to maintain or improve reliability margins.
