Engineering Selection Recommendations

For Active System Designs and New Applications:

The following parts are recommended as primary substitutes for the obsolete SH472M025ST:

SEK472M025ST (Cornell Dubilier Electronics) - Direct manufacturer upgrade within the same product family. Maintains identical electrical specifications while extending operating temperature range to -55°C. Active product status ensures long-term availability and supply chain stability.
EKYB250ELL472MM25S and EKZN250ELL472MM25S (Chemi-Con) - Both offer 10,000-hour lifetime at 105°C, representing a five-fold improvement over the original SH series. Compact form factor (26.50 mm height) provides space optimization benefits. Active product status with established supply chains.
EEU-FC1E472 (Panasonic Electronic Components) - AEC-Q200 rated automotive-grade component with 5,000-hour lifetime. Extended operating temperature range (-55°C to 105°C) and active product status. Suitable for applications requiring automotive-grade reliability.
ELXZ250ELL472MM35S (Chemi-Con) - AEC-Q200 rated with 8,000-hour lifetime and extended temperature range. Active product status with automotive-grade qualification.

For Legacy System Maintenance:

UHE1E472MHD6 and UPW1E472MHD (Nichicon) - Both provide extended lifetime (10,000 and 8,000 hours respectively) and are electrically compatible. Classified as "Not For New Designs" but remain available for repair and maintenance of existing systems. UHE1E472MHD6 offers closest height match to original (35.50 mm vs. 36.00 mm).

For Voltage-Margin Applications:

478CKE035M (Cornell Dubilier / Illinois Capacitor) - 35 V rated variant provides additional voltage margin while maintaining identical capacitance and tolerance. Suitable where circuit design permits higher voltage rating. Active product status.

All listed substitutes are ROHS3 compliant and maintain the 7.50 mm lead spacing required for direct PCB compatibility without layout modification.

Frequently Asked Questions (FAQ)

Q: Can I use a 35 V rated capacitor (478CKE035M) in place of the 25 V SH472M025ST?

A: Yes. The 478CKE035M is electrically compatible and provides additional voltage margin. Higher voltage ratings do not create compatibility issues in circuits designed for lower voltages. The 35 V rating simply indicates the component can safely operate at voltages up to 35 V, making it suitable for 25 V applications.

Q: What is the difference between the Chemi-Con KYB and KZN series substitutes?

A: Both EKYB250ELL472MM25S (KYB) and EKZN250ELL472MM25S (KZN) meet identical electrical specifications: 4700 µF, 25 V, ±20% tolerance, 10,000-hour lifetime at 105°C, and 7.50 mm lead spacing. The KZN variant offers slightly higher ripple current capability (3.298 A @ 120 Hz vs. 3.0005 A) and lower impedance (16 mOhms vs. 17 mOhms). Both are directly interchangeable; selection may be based on inventory availability.

Q: Why do some substitutes have different heights despite identical lead spacing?

A: Capacitor height variation results from different internal construction and winding techniques among manufacturers. The 7.50 mm lead spacing determines PCB hole pattern compatibility. Height differences (ranging from 26.50 mm to 36.50 mm) do not affect electrical function or PCB mounting, though clearance above the board should be verified in space-constrained applications.

Q: Are the Nichicon UHE1E472MHD6 and UPW1E472MHD suitable for new designs?

A: Both are classified as "Not For New Designs" by their manufacturers. They remain electrically compatible and available for legacy system maintenance and repair. For new product development, select from active-status alternatives: SEK472M025ST, EKYB250ELL472MM25S, EKZN250ELL472MM25S, EEU-FC1E472, or ELXZ250ELL472MM35S.

Q: What does AEC-Q200 rating mean for capacitor selection?

A: AEC-Q200 is an automotive industry qualification standard indicating the component has undergone rigorous testing for reliability in automotive environments. EEU-FC1E472 and ELXZ250ELL472MM35S carry this certification, making them suitable for automotive applications or systems requiring automotive-grade component reliability.

Q: Can I substitute based on capacitance and voltage alone?

A: No. Lead spacing (7.50 mm), package type (Radial, Can), and mounting method (Through Hole) are equally critical. These parameters determine physical compatibility with the PCB. All listed substitutes maintain these specifications. Verify lead spacing and package type before selection.

Q: What is the significance of lifetime rating differences (2000 vs. 10,000 hours)?

A: Lifetime rating indicates the expected operational duration at maximum rated temperature (105°C) before capacitance degradation reaches specified limits. The SH472M025ST has a 2000-hour rating; substitutes with 5,000, 8,000, or 10,000-hour ratings provide extended service life. Higher lifetime ratings do not affect immediate compatibility but indicate improved long-term reliability.

Q: Are all listed substitutes RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
