SH102M035ST Equivalent & Substitute Parts Reference

Part Overview

The SH102M035ST is a 1000 µF, 35 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as Obsolete and is no longer recommended for new designs. The SH series represents legacy technology with a rated lifetime of 2000 hours at 105°C, which is significantly lower than modern alternatives currently in active production.

Due to its obsolete status and limited operational lifetime specification, identifying equivalent substitute parts is essential for design continuity, long-term supply chain reliability, and performance optimization in applications requiring extended service life or higher ripple current handling.

Engineering Selection Recommendations

Primary Recommendation for New Designs:

UPW1V102MHD (Nichicon) is the preferred substitute for new circuit designs. This part is classified as Active product status, ensuring long-term availability and supply chain continuity. It provides a 7000-hour lifetime at 105°C, representing a 3.5× improvement over the original SH102M035ST specification. The UPW series maintains identical electrical parameters (1000 µF, 35 V, ±20% tolerance) and mechanical compatibility (5.00 mm lead spacing, radial through-hole package). Operating temperature range extends to -55°C, providing enhanced low-temperature performance.

Secondary Recommendations:

SEK102M035ST (Cornell Dubilier Electronics) offers a direct upgrade path within the same manufacturer family. This part maintains the original CDE heritage while achieving Active product status. Height reduction to 0.827" (21.00 mm) provides PCB layout advantages in space-constrained applications. Lifetime specification matches the original at 2000 hours, making it suitable for direct replacement in legacy systems requiring minimal design modification.

EEU-EB1V102 (Panasonic) and EKY-350ELL102MK25S (Chemi-Con) both provide 10000-hour lifetime ratings at 105°C, representing the highest reliability tier among available substitutes. These parts are recommended for applications requiring extended operational life or high-reliability certifications. Both maintain Active product status and full ROHS3 compliance.

EEU-FC1V102 (Panasonic) is designated for automotive applications with AEC-Q200 qualification. This part is suitable only for designs requiring automotive-grade components and certifications.

Parts Not Recommended for New Designs:

UHD1V102MHD, UHE1V102MHD, and UPS1V102MHD are classified as Not For New Designs. While these parts remain in inventory and are technically compatible, their product status designation indicates manufacturer discontinuation plans. These parts should be reserved for legacy system maintenance and repair only.

Frequently Asked Questions (FAQ)

Q1: Can the SH102M035ST be directly replaced with any of the listed substitutes?

A: Yes. All listed substitute parts maintain identical capacitance (1000 µF), voltage rating (35 V), tolerance (±20%), lead spacing (5.00 mm), and through-hole radial package configuration. Direct PCB footprint compatibility is guaranteed. Physical dimension variations (diameter and height) are within acceptable can package tolerances and do not affect electrical performance or mechanical fit.

Q2: What is the primary advantage of upgrading from SH102M035ST to UPW1V102MHD?

A: The UPW1V102MHD provides a 7000-hour lifetime at 105°C compared to the original 2000-hour specification, representing a 3.5× improvement in operational life. Additionally, UPW1V102MHD is classified as Active product status, ensuring continued availability and supply chain support. The extended temperature range (-55°C to 105°C) provides enhanced performance in cold-environment applications.

Q3: Are there physical dimension differences between the original and substitute parts?

A: Yes. The original SH102M035ST has a diameter of 0.512" (13.00 mm), while most substitutes use 0.492" (12.50 mm) diameter cans. Height variations range from 0.827" to 1.063" depending on the substitute selected. These dimensional differences remain within standard radial can package tolerances and do not affect PCB footprint compatibility or lead spacing (all maintain 5.00 mm spacing). Verify clearance in applications with tight vertical space constraints.

Q4: Which substitute is recommended for applications requiring the longest operational lifetime?

A: Both EEU-EB1V102 (Panasonic) and EKY-350ELL102MK25S (Chemi-Con) provide 10000-hour lifetime ratings at 105°C, the highest specification among available substitutes. Both parts are Active products with full ROHS3 compliance. Selection between these two depends on preferred manufacturer and specific ripple current requirements for your application.

Q5: Can substitutes rated "Not For New Designs" be used in new circuit designs?

A: Parts classified as Not For New Designs (UHD1V102MHD, UHE1V102MHD, UPS1V102MHD) are technically compatible and electrically equivalent. However, this designation indicates manufacturer discontinuation planning. These parts should be reserved for legacy system maintenance, repair, and field replacement only. For new designs, select from parts with Active product status: UPW1V102MHD, SEK102M035ST, EEU-EB1V102, EEU-FC1V102, EKY-350ELL102MK25S, or EKZE350ELL102MK25S.

Q6: Is the EEU-FC1V102 suitable for non-automotive applications?

A: EEU-FC1V102 is designated for automotive applications with AEC-Q200 qualification. While electrically and mechanically compatible with the SH102M035ST, this part should be selected only when automotive-grade certification is a design requirement. For general-purpose applications, UPW1V102MHD, EEU-EB1V102, or EKY-350ELL102MK25S are more appropriate selections.

Q7: What does "ROHS3 Compliant" mean for these capacitors?

A: ROHS3 Compliant indicates full compliance with the Restriction of Hazardous Substances Directive (RoHS 3), which restricts the use of specific hazardous materials in electrical and electronic equipment. All listed substitute parts, including the original SH102M035ST, meet this environmental and regulatory requirement. This compliance is mandatory for products sold in European Union markets and increasingly required globally.

Q8: Are there ripple current differences between substitutes?

A: Yes. Ripple current ratings vary among substitutes. The original SH102M035ST specifies 995 mA at 120 Hz and 1.393 A at 10 kHz. Substitutes with lower ESR and impedance values (such as EKZE350ELL102MK25S with 18 mOhms impedance) provide higher ripple current handling capability. For applications with high AC ripple current requirements, select substitutes with lower impedance specifications.

Q9: What is the significance of extended operating temperature ranges (-55°C vs. -40°C)?

A: The original SH102M035ST operates from -40°C to 105°C. Several substitutes extend the lower temperature limit to -55°C (SEK102M035ST, EEU-FC1V102, UPS1V102MHD, UPW1V102MHD). This extended range provides performance assurance in cold-environment applications, industrial equipment operating in unheated spaces, or aerospace/defense applications. For standard commercial temperature range applications (-40°C to 105°C), all substitutes are functionally equivalent.

Q10: How should I select between multiple "Active" status substitutes?

A: Selection among active substitutes (UPW1V102MHD, SEK102M035ST, EEU-EB1V102, EEU-FC1V102, EKY-350ELL102MK25S, EKZE350ELL102MK25S) depends on application-specific requirements: (1) Lifetime requirement: Select 10000-hour parts (EEU-EB1V102, EKY-350ELL102MK25S) for extended-life applications; (2) Ripple current: Select lower-impedance parts (EKZE350ELL102MK25S, EEU-FC1V102) for high-ripple applications; (3) Manufacturer preference: CDE (SEK102M035ST), Panasonic (EEU series), Nichicon (UPW1V102MHD), or Chemi-Con (EKY/EKZE series); (4) Physical space: SEK102M035ST offers reduced height (0.827") for compact designs; (5) Automotive certification: EEU-FC1V102 for AEC-Q200 requirement.
