SH222M025ST Equivalent & Substitute Parts Reference

Part Overview

The SH222M025ST is a 2200 µF, 25 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is rated for general-purpose applications with an operating temperature range of -40°C to 105°C and a lifetime specification of 2000 hours at 105°C. The part is currently obsolete, making equivalent substitutes necessary for ongoing system support and new production requirements. Active alternatives from major manufacturers provide extended lifetime ratings and improved performance characteristics while maintaining electrical and mechanical compatibility.

Engineering Selection Recommendations

Direct Substitutes (Preferred for Replacement):

The following parts are direct substitutes with active product status and extended lifetime ratings:

25ZLH2200MEFC16X20 (Rubycon ZLH series): Active status, 10000-hour lifetime at 105°C, reduced height (22.00 mm vs. 25.00 mm original), suitable for space-constrained applications.
25ZLJ2200M16X20 (Rubycon ZLJ series): Active status, 10000-hour lifetime at 105°C, reduced height (22.00 mm), higher ripple current capability at 120 Hz (2.331 A).
EEU-FR1E222S (Panasonic FR-A series): Active status, 10000-hour lifetime at 105°C, reduced height (22.00 mm), bulk packaging, highest ripple current at 120 Hz (2.64 A).
EKZM250EC5222ML20S (Chemi-Con KZM series): Active status, 10000-hour lifetime at 105°C, reduced height (21.50 mm), lowest impedance (15 mOhms).

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different height than the original SH222M025ST?

A: Yes. The substitute parts with reduced heights (21.50 mm to 22.00 mm vs. 25.00 mm original) are mechanically compatible. Verify available vertical clearance in your application. The UPW1E222MHD maintains the original 25.00 mm height if space constraints require height matching.

Q: What is the difference between the Rubycon ZLH and ZLJ series substitutes?

A: Both 25ZLH2200MEFC16X20 and 25ZLJ2200M16X20 are electrically and mechanically equivalent. The ZLJ variant has slightly higher ripple current capability at 120 Hz (2.331 A vs. 2.275 A) and higher impedance (21 mOhms vs. 15 mOhms). Select based on ripple current requirements in your specific circuit.

Q: Why do the Chemi-Con KZM and KZN series have different impedance values?

A: EKZM250EC5222ML20S and EKZM250ELL222ML20S (KZM series) have 15 mOhms impedance, while EKZN250ELL222ML20S (KZN series) has 21 mOhms impedance. Both are electrically and mechanically equivalent substitutes. The impedance difference reflects internal construction variations. Select based on your circuit's ESR sensitivity requirements.

Q: Is the Nichicon UPW1E222MHD suitable as a direct replacement?

A: Yes. The UPW1E222MHD is a direct substitute with active product status. It maintains the original 25.00 mm height and provides an extended operating temperature range (-55°C to 105°C). The 8000-hour lifetime at 105°C is lower than other active substitutes (10000 hours), but exceeds the original 2000-hour specification. Select this part when lower temperature operation is required.

Q: What is the difference between EEU-FR1E222S and EEU-FR1E222SB?

A: Both parts are electrically and mechanically identical. EEU-FR1E222S is supplied in bulk packaging, while EEU-FR1E222SB is supplied in Cut Tape (CT) format. Select EEU-FR1E222SB when automated pick-and-place assembly requires tape-and-reel packaging.

Q: Can I substitute the SH222M025ST with a part having a different voltage rating?

A: No. The voltage rating must match exactly at 25 V. Using a lower voltage rating creates an overstress condition. Using a higher voltage rating (such as 35 V or 50 V) changes the physical dimensions and may not fit the PCB layout.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed in this reference are ROHS3 compliant and suitable for applications requiring regulatory compliance with RoHS Directive 2011/65/EU.

Q: What is the lead spacing tolerance, and does it affect substitution?

A: All parts, including the original SH222M025ST and all substitutes, have a lead spacing of 0.295" (7.50 mm). This dimension is standardized and does not vary among the listed parts. PCB hole patterns are compatible without modification.

Q: Which substitute offers the best performance improvement over the original SH222M025ST?

A: The Panasonic EEU-FR1E222S and Chemi-Con EKZM250ELL222ML20S offer the most significant improvements: 10000-hour lifetime at 105°C (5× the original 2000 hours), reduced height (22.00 mm and 21.50 mm respectively), and active product status ensuring long-term availability. Select based on your specific space and reliability requirements.
