Equivalent & Substitute Parts for SH102M025ST

Part Overview

The SH102M025ST is a 1000 µF, 25 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, indicating it is no longer in active production. The SH series represents legacy technology in the general-purpose capacitor category.

Due to the obsolete status of SH102M025ST, identifying equivalent and substitute parts is necessary for ongoing maintenance, repair, and redesign applications. Substitute components must maintain electrical and mechanical compatibility while meeting current manufacturing standards and compliance requirements.

Engineering Selection Recommendations

Direct Replacement (Highest Compatibility):

108CKE025M (Cornell Dubilier / Illinois Capacitor, CKE Series) is the most direct substitute. It maintains identical electrical specifications (1000 µF, ±20%, 25 V) and mechanical compatibility (5.00 mm lead spacing, radial through-hole package). The component is in active production status with ROHS3 compliance. Physical dimensions are slightly smaller (10.00 mm diameter, 17.50 mm height), which provides improved board space efficiency while maintaining electrical performance. ESR specification (232.1 mOhm @ 120 Hz) is marginally higher than the original but within acceptable tolerance for general-purpose applications.

Upgraded Alternatives (Enhanced Performance):

EEU-EB1E102 (Panasonic, EB-A Series) offers extended lifetime (10000 Hrs @ 105°C versus 2000 Hrs) with active product status. Electrical parameters match the original specification. Physical dimensions are slightly larger (12.50 mm diameter, 22.00 mm height), requiring verification of available board space. This option is suitable for applications requiring extended operational life.

EEU-FC1E102 (Panasonic, FC Series) provides automotive-grade qualification (AEC-Q200) with 5000 Hrs lifetime and extended operating temperature range (-55°C to 105°C). This component is appropriate for automotive or harsh environment applications. Physical dimensions (12.50 mm diameter, 20.00 mm height) are compatible with standard through-hole spacing.

EKZE250ELL102MK20S (Chemi-Con, KZE Series) offers superior ripple current handling (2.36 A @ 100 kHz) and low impedance (21 mOhms) with 5000 Hrs lifetime. This option is suitable for high-ripple-current applications. Physical dimensions (12.50 mm diameter, 21.50 mm height) require board space verification.

Alternative with Voltage Margin:

UPA1V102MHD (Nichicon, UPA Series) provides 35 V voltage rating, offering additional voltage margin over the original 25 V specification. This component is in active production with 5000 Hrs lifetime and extended operating temperature range (-55°C to 105°C). Physical dimensions match standard through-hole compatibility (12.50 mm diameter, 20.00 mm height). The higher voltage rating provides design flexibility for applications with potential voltage transients.

Legacy Alternative (Not Recommended for New Designs):

UHE1E102MHD6 (Nichicon, UHE Series) is marked "Not For New Designs" and should be avoided for new applications. While it offers 10000 Hrs lifetime and meets all critical electrical and mechanical parameters, its obsolescence status makes it unsuitable for long-term supply chain planning.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher voltage rating than the original SH102M025ST?

A: Yes. A substitute with equal or higher voltage rating is acceptable. UPA1V102MHD (35 V) can replace SH102M025ST (25 V) because the higher voltage rating provides additional safety margin. The capacitance, tolerance, and physical form factor remain identical.

Q: What is the significance of the different physical dimensions among substitute parts?

A: Physical dimensions (diameter and height) determine whether a substitute part fits within the available PCB space. 108CKE025M is smaller (10.00 mm diameter, 17.50 mm height) than the original (13.00 mm diameter, 20.00 mm height), providing space savings. Larger alternatives like EEU-EB1E102 (22.00 mm height) require verification that board clearance is available. Lead spacing (5.00 mm) remains constant across all substitutes, ensuring PCB footprint compatibility.

Q: Why do some substitute parts have unspecified ESR values?

A: ESR (Equivalent Series Resistance) is a performance characteristic that varies by manufacturer and series design. When ESR is not specified in the provided data, it indicates the manufacturer has not published this parameter for the specific part number. This does not indicate inferior performance; it reflects different documentation practices. For applications where ESR is critical, contact the manufacturer for detailed specifications.

Q: Is RoHS3 compliance mandatory for substitution?

A: All listed substitute parts are ROHS3 compliant, matching the original SH102M025ST. RoHS3 compliance is a regulatory requirement for components used in most modern applications and should be verified for your specific market and application requirements.

Q: What does "Not For New Designs" mean for UHE1E102MHD6?

A: This designation indicates the manufacturer (Nichicon) has classified this part as obsolete or end-of-life for new product development. While the component may still be available in inventory, it should not be selected for new designs due to uncertain long-term supply availability. For new applications, select from parts with "Active" product status.

Q: Can I substitute SH102M025ST with a capacitor rated for a lower voltage?

A: No. A substitute must have equal or higher voltage rating than the original. Using a lower-rated voltage capacitor creates risk of component failure and circuit malfunction. All listed substitutes maintain the 25 V minimum rating or exceed it.

Q: How do I determine if a substitute part fits my PCB layout?

A: Verify three parameters: (1) Lead spacing must be 5.00 mm to match the original PCB footprint; (2) Diameter must fit within available radial space; (3) Height must not exceed available vertical clearance. All listed substitutes maintain 5.00 mm lead spacing. Compare the diameter and height specifications against your PCB design constraints.

Q: What is the difference between "Bypass" and "Decoupling" applications listed for 108CKE025M?

A: Both terms describe similar functional uses in power supply filtering. Bypass capacitors filter high-frequency noise from power lines, while decoupling capacitors suppress voltage transients near integrated circuits. The 108CKE025M is suitable for both applications. The original SH102M025ST lists "General Purpose," which encompasses these functions.
